CHAPTER IX

JOSEPH IBN ZADDIK

Little is known of the life of Joseph ben Jacob ibn Zaddik. He lived in

Cordova; he was appointed _Dayyan_, or Judge of the Jewish community of

that city in 1138; and he died in 1149. He is praised as a Talmudic

scholar by his countryman Moses ibn Ezra, and as a poet by Abraham ibn

Daud and Harizi, though we have no Talmudic composition from his pen,

and but few poems, whether liturgical or otherwise.[162] His fame rests

on his philosophical work, and it is this phase of his career in which

we are interested here. "Olam Katon" or "Microcosm" is the Hebrew name

of the philosophical treatise which he wrote in Arabic, but which we no

longer possess in the original, being indebted for our knowledge of it

to a Hebrew translation of unknown authorship.[163] Maimonides knew

Joseph ibn Zaddik favorably, but he was not familiar with the

"Microcosm." In a letter to Samuel Ibn Tibbon, the translator of his

"Guide of the Perplexed," Maimonides tells us that though he has not

seen the "Olam Katon" of Ibn Zaddik, he knows that its tendency is the

same as that of the Brothers of Purity (_cf._ above, p. 60).[164] This

signifies that its trend of thought is Neo-Platonic, which combines

Aristotelian physics with Platonic and Plotinian metaphysics, ethics and

psychology.

An examination of the book itself confirms Maimonides's judgment. In

accordance with the trend of the times there is noticeable in Ibn Zaddik

an increase of Aristotelian influence, though of a turbid kind; a

decided decrease, if not a complete abandonment, of the ideas of the

Kalam, and a strong saturation of Neo-Platonic doctrine and point of

view. It was the fashion to set the Kalam over against the philosophers

to the disadvantage of the former, as being deficient in logical

knowledge and prejudiced by theological prepossessions. This is attested

by the attitude towards the Mutakallimun of Judah Halevi, Maimonides,

Averroes. And Ibn Zaddik forms no exception to the rule. The

circumstance that it was most likely from Karaite writings, which found

their way into Spain, that Ibn Zaddik gained his knowledge of Kalamistic

ideas, was not exactly calculated to prepossess him, a Rabbanite, in

their favor. And thus while we see him in the manner of Saadia and Bahya

follow the good old method, credited by Maimonides to the Mutakallimun,

of starting his metaphysics with proofs of the world's creation, and

basing the existence of God, his unity, incorporeality and other

attributes on the creation of the world as a foundation, he turns into

an uncompromising opponent of these much despised apologetes when he

comes to discuss the nature of God's attributes, of the divine will, and

of the nature of evil. And in all these cases the target of his attack

seems to be their Karaite representative Joseph al-Basir, whose

acquaintance we made before (p. 48 ff.).

He laid under contribution his predecessors and contemporaries, Saadia,

Bahya, Pseudo-Bahya, Gabirol; and his sympathies clearly lay with the

general point of view represented by the last, and his Mohammedan

sources; though he was enough of an eclectic to refuse to follow

Gabirol, or the Brethren of Purity and the other Neo-Platonic writings,

in all the details of their doctrine; and there is evidence of an

attempt on his part to tone down the extremes of Neo-Platonic tendency

and create a kind of level in which Aristotelianism and Platonism meet

by compromising. Thus he believes with Gabirol that all things corporeal

as well as spiritual are composed of matter and form;[165] but when it

comes to defining what the matter of spiritual things may be, he tells

us that we may speak of the genus as the matter of the species--a

doctrine which is not so Neo-Platonic after all. For we do not have to

go beyond Aristotle to hear that in the definition of an object, which

represents its _intelligible_ (opposed to sensible) essence, the genus

is like the matter, the difference like the form. Of the universal and

prime matter underlying all created things outside of God, of which

Gabirol says that it is the immediate emanation of God's essence and

constitutes with universal form the Universal Intelligence, Ibn Zaddik

knows nothing. Nor do we find any outspoken scheme of emanation, such as

we see in Plotinus or with a slight modification in the cyclopoedia of

the Brethren of Purity, or as it is presupposed in the "Fons Vitæ" of

Gabirol. Ibn Zaddik does refer to the doctrine of the divine Will, which

plays such an important rôle in the philosophy of Gabirol and of the

Pseudo-Empedoclean writings, which are supposed to have been Gabirol's

source.[166] But here, too, the negative side of Ibn Zaddik's doctrine

is developed at length, while the positive side is barely alluded to in

a hint. He takes pains to show the absurdity of the view that the divine

will is a momentary entity created from time to time to make possible

the coming into being of the things and processes of our world--a view

held by the Mutakallimun as represented by their spokesman al-Basir, but

when it comes to explaining his own view of the nature of the divine

will, and whether it is identical with God or not, he suddenly becomes

reticent, refers us to the writings of Empedocles, and intimates that

the matter is involved in mystery, and it is not safe to talk about it

too plainly and openly. Evidently Ibn Zaddik was not ready to go all the

length of Gabirol's emanationism and Neo-Platonic mysticism.

The Aristotelian ideas, of which there are many in the "Microcosm," are

probably not derived from a study of Aristotle's works, but from

secondary sources. This we may safely infer from the way in which he

uses or interprets them. An Aristotelian definition is a highly

technical proposition in which every word counts, and requires a

definition in turn to be understood. In the Aristotelian context the

reader sees the methodical derivation of the concept; and the several

technical terms making up the definition are made clear by illustrative

examples. Aside from the context the proposition is obscure even in the

original Greek. Now conceive an Arabic translation of an Aristotelian

definition taken out of its context, and you do not wonder that it is

misunderstood; particularly when the interpreter's point of view is

taken from a school of thought at variance with that of Aristotle. This

is exactly what happens to Ibn Zaddik. He quotes approvingly Aristotle's

definition of the soul, and proceeds to interpret it in a manner not

intended by the author of the "De Anima."[167] If he had read the

context he could not have misunderstood the definition as he did.

Unlike his predecessors, Ibn Zaddik did not confine himself to a special

topic in philosophy or to the metaphysical aspects of Judaism. Isaac

Israeli and Gabirol discuss special questions in Physics and Metaphysics

without bringing them into relation with Judaism or the text of the

Bible. Saadia takes cognizance of philosophical doctrine solely with a

view to establishing and rationalizing Jewish dogma, and only in so far

as it may thus be utilized. Bahya and Abraham bar Hiyya confine their

philosophical outlook within still narrower limits, having Jewish ethics

as their primary concern. All of the latter make a feature of Biblical

interpretation, which lends to their work the Jewish stamp and to their

style the element of homeliness and variety. To this they owe in a

measure their popularity, which, however, cannot be said for Abraham bar

Hiyya, whose "Hegyon ha-Nefesh" was not printed until the second half of

last century. The "Microcosm" of Ibn Zaddik is the first compendium of

science, philosophy and theology in Jewish literature. And yet it is a

small book; for Ibn Zaddik does not enter into lengthy discussions, nor

does he adorn his style with rhetorical flourishes or copious quotations

from Bible and Talmud. The "Olam Katon" is clearly meant for beginners,

who require a summary and compendious view of so much of physics,

psychology, metaphysics and ethics as will give them an idea of the

position of man in the world, and his duties, theoretical and practical,

in this life, that he may fulfil his destiny for which he was created.

It is very possible that Ibn Zaddik modelled his work on the

Encyclopædia of the Brethren of Purity, leaving out all that he regarded

as unessential or objectional and abridging the rest.

Accordingly, the "Microcosm" is divided into four parts. The first part

treats of what is called in the Aristotelian classification of the

sciences Physics, _i. e._, the principles and constitution of the

corporeal world and its processes. The second treats of man, including

anthropology and psychology. The third is devoted to a discussion of the

existence, unity, incorporeality and other attributes of God, based upon

the doctrine of the creation of the world. This bears the stamp of the

Kalam, and is indebted to the writings of Saadia, Bahya and Joseph

al-Basir. It covers the topics usually treated by the Mutakallimun in

the division of their works, known by the name of "Bab al Tauhid,"

treatise on Unity. The fourth part corresponds to the "Bab al Adi" of

the Kalam, _i. e._, the second division of Kalamistic works devoted to

theodicy, or vindication of God's justice in his dealings with mankind.

Hence it includes theological questions of an ethical nature, like

freedom of the will, reasons for divine worship, the nature of reward

and punishment, and so on.

The book was written, Ibn Zaddik tells us, in answer to the question of

a pupil concerning the meaning of such terms as "perfection" and

"permanent good," used by philosophers. They are not of this world these

men say, and yet every man of intelligence should seek them. This is a

very difficult subject, made more so by the small number of persons

engaged in its study. Particularly in our own generation is this true,

that the value of knowledge and investigation is not recognized. People

are Jews in name only, and men only in outward appearance. Former ages

were much superior in this regard.

Two fundamental requisites are necessary for the knowledge of our

subject. They are the knowledge of God, and performance of his will. For

this purpose we must understand the works of the philosophers. But these

in turn require a knowledge of the preliminary sciences of arithmetic,

geometry, music, astronomy, and logic. This takes a long time and is

likely to weary the student, especially the beginner. I have therefore

made it my purpose to show how a man can know himself, for from a

knowledge of self he will come to a knowledge of all. Man is called

"Microcosm," a world in miniature, because he has in him represented all

the elements of the universe. His body resembles the corporeal world;

his rational soul the spiritual world. Hence the importance of knowing

himself, and hence the definition of philosophy as a man's _knowledge of

himself_. Philosophy is the science of sciences and the end thereof,

because it is the path to a knowledge of the Creator.[168]

Here we see at the outset Ibn Zaddik's Neo-Platonic tendency to make a

short cut to knowledge through the study of man instead of the painful

and laborious mastery of the preliminary sciences. And so it was that

the Neo-Platonists added little to Aristotle's study of nature,

concentrating their attention upon the intelligible or spiritual world.

The first thing we must do then is to show that the human body is

similar to the corporeal world. This will require an analysis of the

structure of the latter. But before examining the _objects_ of

knowledge, we must say a word about the process of knowing. Man

perceives things in two ways--through sense and through intellect. His

senses give him the accidents of things, the shell or husk, so to speak.

He perceives color through sight, sound through hearing, odor through

smell, and so on. It takes reason to penetrate to the essence of an

object. Take as an example a book. The sense of sight perceives its

color, and through the color its form. This is then apprehended by the

power of imagination or representation. The latter in turn hands it over

to the cogitative power of the rational soul, from the reflection of

which results the spiritual reality of the object, which is its

knowledge. So we see that the reason knows the essence and reality of a

thing, whereas the senses know only its husk and its accidents. This

same thing is stated by the philosopher in another form. The senses, he

says, know only the particular, the universal can be known by the

intellect only. This is because the soul is fine and penetrating, while

the body is gross, and can reach the surface only.

We may also classify knowledge from another point of view as necessary

(or immediate), and demonstrated (or mediate). Necessary knowledge is

that which no sane man can deny. Such knowledge may be of the senses, as

the sight of the sun or the sound of thunder; or it may be of the

reason, such as that the whole is greater than its parts. We may then

enumerate four kinds of things known directly without the help of other

knowledge, (1) The percepts of the senses. (2) Truths generally admitted

by reason of their self-evidence. (3) Traditional truths, _i. e._,

truths handed down by a reliable and wise man, or by a community worthy

of credence. (4) First principles or axioms. These four can be easily

reduced to two; for traditional truths ultimately go back to the

testimony of the senses; while first principles or axioms are included

in self-evident propositions. We thus have two kinds of necessary or

immediate knowledge, the data of sense, and self-evident propositions.

The latter kind is superior to the former, because man shares sense

knowledge with the lower animals; whereas rational propositions are

peculiar to him alone.

Demonstrated knowledge is built upon necessary knowledge, and is derived

from it by means of logical inference.[169]

We may now proceed to discuss the principles of the corporeal world.

Matter is the foundation and principle of a thing. All things, natural

as well as artificial, are composed of matter and form. Wood is the

common matter of chair and bed. Their forms are different. So the common

matter of the four elements is the prime matter endowed with the form of

corporeality, _i. e._, with the capacity of filling place. This form of

corporeality makes the prime matter corporeal substance. Matter is

relative to form, form is relative to matter.

Spiritual things also have matter and form. In corporeal artificial

things like ring or bracelet, the matter is gold, the form is the form

of ring or bracelet, the efficient cause is the art of the goldsmith,

the final cause or purpose is the adornment. In spiritual things we may

compare genus to matter, species to form, specific difference to

efficient cause, the individual to the final cause.

Everything exists either by itself (_per se_) or in something else.

Matter exists by itself, form exists in something else, in matter.

Matter is potentially substance; after it assumes a form it becomes

actual substance. In reality there is no matter without form, but in

thought we can remove the form and leave the matter.

Substance may be described as that which bears opposite and changing

qualities. No substance can be the opposite of another substance through

its substantiality, but through its accidents; for opposition resides in

quality. Matter receiving form is substance. Absolute substance is

simple and spiritual, for it cannot be perceived through the five

senses. When the philosophers say that all body is substance, and that

the individual is a substance, they use substance in contradistinction

to accident, meaning that the individual exists by itself, and needs not

another for its existence, unlike accidents, which must have something

to exist in.

This absolute substance, which is simple and spiritual, seems to be

identical with Gabirol's "substantia quæ sustinet decem prædicamenta,"

the substance which supports the ten categories. Gabirol means by it

that which remains of a corporeal substance when we take away from it

everything that qualifies it as being here or there, of a particular

nature or size, in a given relation, and so on.

The expression corporeal world includes the celestial spheres and all

which is under them. To be sure, the body of the sphere is different

from the other bodies in matter and form and qualities. It consists of a

fifth nature, different from the four elements. It is not cold, or it

would move downward like earth and water. It is not warm, or it would

move upward like air and fire. It is not wet, for it would then roll

like the waves of the sea. Nor is it dry, for it would condense and not

move at all. Not being any one of these qualities, which constitute our

four elements, the sphere is not a composite of them either; for the

simple is prior to the composite, and we cannot regard the elements of

the sublunar world as prior and superior to the spheres.

The sphere is neither light nor heavy. For light and heavy are relative

terms. An object is heavy when out of its natural place, light when in

its natural place. Thus a stone is heavy when it is away from the earth,

which is its natural place, but is light when it comes to rest where it

belongs. The sphere is never out of its place or in its place, as it

moves constantly in a circle. Hence it is neither light nor heavy.

Ibn Zaddik's definition of light and heavy as being relative, and

dependent on the relation of the object to its natural place is

peculiar, and would lead him to say that fire and air are also heavy

when out of their natural place, which is outside of, and above earth

and water. But this does not seem in consonance with the Aristotelian

use of these terms. According to Aristotle an object is heavy if its

tendency is to move to the centre of the world; it is light if it moves

away from the centre to the circumference. Hence earth and water are

heavy, fire and air are light. The natural place of a body or element is

that to which it has a tendency to move, or in which it has a tendency

to rest, when left to itself. Hence a body will always move to its

natural place when away from it and under no restriction; and its

heaviness or lightness does not change with its position.

To continue, the sphere moves in a circle, the most perfect of all

motions, having neither beginning nor end. It is more perfect than all

bodies, and the knowledge of God is not hidden from it as it is hidden

from us. Whatever moves in a circle must move around a body at rest; for

if it moves around another moving body, this second body must have

another body around which it moves, and this third body another, and so

on _ad infinitum_, which is impossible. Hence the sphere moves around a

body at rest. This is the earth.

The four elements of the sublunar world are, fire, air, water, earth. In

their purity these elements have neither color nor taste, nor odor nor

any other sensible property. For the elements are simple bodies, whereas

the sensible qualities are the result of the composition of the

elements. If air had color, we should see it as we see all colored

things; and all other things would appear to us in the color of air, as

is the case when we look through a colored glass. The same argument

applies to water.

The elements change into each other. We see water changing under the

effect of heat into vapor, and the vapor condenses again under the

influence of cold and changes back to water, namely, rain. Air changes

into fire when flint strikes iron. Fire cannot exist here unless it has

something to take hold of; otherwise it changes into air. Earth and

water change into each other very slowly, because earth is hard to

change.

The basis of the four elements is a substance filling place as a result

of its assuming the form of corporeality, _i. e._, extension in three

directions. Filling place, it moves; moving, it becomes warm. When its

motion is completed, it necessarily comes to rest and becomes cold. Heat

and cold are the active powers, wet and dry are the passive qualities,

wet being associated with heat, dry with cold. The mixture of these

qualities with the corporeal basis results in the four elements.

The three natures, mineral, plant, animal are composed of the four

elements. When a seed is put in the ground it cannot grow without water,

and sunshine and air. These form its food, and food is assimilated to

the thing fed. Our bodies are composed of the four elements, because

they are nourished by plants. The general process of the sublunar world

is that of genesis and dissolution. The genesis of one thing is the

dissolution of another. The dissolution of the egg is the genesis of the

chicken; the dissolution of the chicken is the genesis of the four

elements; for in the living being the elements are potential, and they

become actual when the animal dies. This continuous process of genesis

and dissolution proves that this world is not permanent, for the basis

of its processes is change.[170]

The human body corresponds to the corporeal world, and is similar to it

in its nature and matter. Man's body is subject to genesis and decay

like other objects. It is composed of the elements and returns to them.

It has in it the nature of minerals, plants and animals. It has the

power of growth, sustenance and reproduction like plants. Man is like

animal in having motion and sensation. He has the spirited power and the

appetitive like other animals. His body is perfect because it has

resemblances to all kinds of plants and animals. His body as a whole

resembles great trees, his hair is like grass and shrubs. Animals have

various qualities according to the relation of the animal soul to the

body. Thus the lion has strength, the lamb meekness, the fox shrewdness,

and so on. Mankind includes all of these qualities. In the same way

various animals have various instincts resembling arts, such as the

weaving of the spider, the building of the bird and the bee, and so on.

They also subsist on various foods. Man alone combines all arts and all

kinds of food.

The human body has three dimensions like inanimate bodies. It is also

similar to the bodies of plants and animals, and at the same time is

distinguished alone among animals by its erect position. This is due to

the fact that man's nature is proportionate, and his body is purer and

finer than other bodies. Thus we see when oil is pure, its flame rises

in a straight line; when the oil is impure the flame is not straight.

Another thing proving that man's nature is superior to that of other

animals is that the latter live in that element which is akin to their

constitution--fish in water, birds in air, quadrupeds on land. Man alone

can inhabit all three. Another reason for man's erect position is that

he is a plant originating in heaven. Hence his head, which is the root,

faces heaven.[171]

Man has three souls, a plant soul, an animal soul and a rational soul.

He must have a plant soul to account for the fact that man grows like

other plants and dies like them. For if he can grow without a plant

soul, plants can do the same. And if this too is granted, then there is

no reason why mountains and stones should not grow also. Again, if man

can grow without a plant soul, he can live without an animal soul, and

know without a rational soul, which is absurd.

The faculty of the vegetative soul is the appetitive power, whose seat

is in the liver. Its subordinate powers are those of nutrition and

growth. Through it man feels the need of food and other natural desires.

He has this in common with the lower animals. It is the first power that

appears in man while he is still in his mother's womb. First comes the

power which forms the combined seed of the male and the female into a

human being in its proper form and nature. In doing this it requires the

assistance of the "growing" power, which begins its activity as soon as

the first member is formed, and continues until the period of youth is

completed. This power in turn needs the assistance of the nourishing

power, which accompanies the other two from the beginning of their

activity to the end of the person's life. All this constitutes the plant

soul, and it must not be supposed that these powers are separated from

one another, and that one is in one place and another in another place.

_They are all spiritual powers derived from the universal powers in the

upper world._

When the form of the being is complete, the animal soul makes its

appearance. This soul is carried in the spirit of the animal or man,

which is found in the pure blood of the arteries. There are two

membranes in every artery, making two passages, one for blood and the

other for the spirit or wind. The seat of the animal soul is in the

heart, and it is borne in the pure red blood. This is why we see in the

heart two receptacles; in one is spirit, in the other, blood. Hence

after death we find congealed blood in the one, while the other is

empty. Death happens on account of the defective "mixture" of the heart.

This means that the four humors of which the body is composed, namely,

blood, yellow and black gall and phlegm, lose the proper proportionality

in their composition, and one or other of them predominates. An animal

does not die unless the mixture of the heart is injured, or the heart is

wounded seriously. Death is also caused by disease or injury of the

brain. For the brain is the origin of the nerves which control the

voluntary activities by means of contraction and expansion. If the chest

does not contract, the warm air does not come out; if it does not

expand, the cold air does not come in; and if the air does not come in

or out, the heart loses its proportionality, and the animal dies. The

functions of the animal soul are sensation and motion. This motion may

be active as well as passive. The active motions are those of the

arteries, and the expansion and contraction of the chest which results

in respiration. The passive motions give rise to the emotions of anger,

fear, shame, joy, sorrow.

Anger is the motion of the spirit within the body toward the outside,

together with the blood and the humors. This is found in animals also.

Fear is the entrance of the soul within, leaving the surface of the

body, and causing the extremities to become cold. Shame is a motion

inward, and forthwith again outward. Sorrow is caused in the same way as

fear, except that fear is sudden, while sorrow is gradual. This is why

fear sometimes kills when the body is weak. Joy is motion outward. Joy

may kill too, when it is very great, and the person is weak and without

control. Joy is of the nature of pleasure, except that pleasure is

gradual, while joy is sudden.

Pain is that feeling we have when we are taken out of our natural state

and put into an unnatural. Pleasure is felt when we are restored to the

natural. Take, for example, the heat of the sun. When a person is

exposed to it, the sun takes him out of his natural state. Heat is then

painful, and pleasure is produced by the thing which restores him to his

natural state; in this case a cold spring and a drink of cold water.

Similarly a person walking in the snow and cold air feels pain by reason

of the cold taking him out of his natural state. Heat then gives him

pleasure by restoring him. The same thing applies to hunger and thirst,

sleeping and waking, and other things which give us pleasure and pain.

Without pain there is no pleasure, and the pleasure varies in accordance

with the antecedent pain.

Life is the effect of the animal soul. The disappearance of the effect

does not necessarily involve the disappearance of the cause, as the

disappearance of the smoke does not require the cessation of the fire.

Death means simply the separation of the soul, not the destruction

thereof. It does not follow because the human soul remains after the

death of the body, that the soul of the ox and the ass continues

likewise, for the two souls are different. Animals were created for the

sake of man, whereas man exists for his own sake. Moreover, man's life

is ultimately derived from his rational soul. For if the animal soul of

man were the ultimate source of life, the rational soul too would be

dependent for its life upon the former, and hence would be inferior to

it, which is absurd. It remains then that the _rational soul gives

existence to the animal soul in man_.

Sleep is the rest of the senses, as death is their entire cessation. The

purpose of sleep is to give the brain rest so that the "spirit" of the

soul should not be dissolved and the "mixture" of the body injured

suddenly and cause death. The heart rests continually between

contraction and expansion, hence it needs no special rest at night.

Waking is the activity of the senses and the exercise of their functions

to satisfy the desires of the body. The motions of the soul in the

waking state are in the interest of the needs of the body. During sleep

the soul looks out for itself, for its better world, being then free

from the business of the body. If it is pure and bright, and the body

is free from the remnant of food, and the thought is not depressed by

sorrow and grief--then the soul is aroused in its desire for the future,

and beholds wonderful things.[172]

No one can deny that man has a rational soul because speech is an

attribute which man has above all other animals. The soul is not a

corporeal thing, for if it were it would have to occupy place like body,

and would have color and form and other qualities like body. Moreover,

it would require something else to give it life like body. In other

words, the soul would require another soul, and that soul another soul,

and so on _ad infinitum_, which is impossible. Hence the soul is not a

corporeal thing.

Nor can we say that the soul is _in_ the body. For if it were, it would

itself be body; since only body can fill the empty place in another

body, as water fills a jar.

The soul is a substance and not an accident. An accident is a quality

which makes its appearance in something else, and has no permanence. If

then the rational soul is an accident of the body, it has no permanence,

and man is sometimes rational and sometimes not. This is absurd, for in

that case there could be no purpose in giving him commandments and

statutes.

There are inseparable accidents to be sure, like the color of the

Ethiopian's skin. But in that case we know the color is an accident

despite its inseparability, from the fact that in other things color is

an accident and may be removed. This will not apply to the reason. For

we do not find anything in which reason is a removable accident. The

moment you remove reason, you remove man, for reason is essential to

man. The fact that as a result of an injury a man may lose his reason is

no argument against us, for this happens only when an injury is

inflicted on the brain, which is the reason's instrument. This accounts

for the fact, too, that men in good health if given henbane to drink

lose their reason, because the drink affects the brain. On the other

hand, we see that those afflicted with a certain disease of the

intestines, which causes their death, are more rational and brighter at

the time of death than ever before, showing that the soul cannot be an

accident depending upon the "mixture" of the body.

To regard the soul as an accident, while the body is a substance, would

make the soul inferior to the body. This is absurd. For we have the

body in common with the beasts; whereas it is in virtue of the reason

that we are given commandments, and reward and punishment in the world

to come.

If the soul is neither a corporeal thing nor an accident of body, it

must be a spiritual substance. And the best definition of the soul is

that of Aristotle, who says it is _a substance giving perfection to a

natural organic body, which has life potentially_. Every phrase in this

definition tells. "Substance" excludes the view that the soul is an

accident. "Giving perfection" signifies that the soul is that which

makes man perfect, bringing him to the next world, and being the purpose

not merely of his creation and the composition of his body, but of the

creation of matter as well. "Natural organic body" indicates that the

body is an organon, or instrument in the function of the soul, the

latter using the body to carry out its own purposes. The rational soul

is like a king; the animal soul is like an official before the king,

rebuking the appetitive soul.

In the discussion of the last paragraph we have a good example of the

uncritical attitude of Ibn Zaddik toward the various schools of

philosophical thought, particularly those represented by Plato and

Aristotle. This attitude is typical of the middle ages, which appealed

to authority in philosophy as well as in theology, and hence developed a

harmonistic attitude in the presence of conflicting authorities. Aided

by their defective knowledge of the complete systems of the ancient

Greek philosophers, by the difficulties and obscurities incident to

translations from an alien tongue, and by the spurious writings

circulating in the name of an ancient Greek philosopher, the precise

demarcation of schools and tendencies became more and more confused, and

it was possible to prove that Plato and Aristotle were in entire

agreement. Thus Ibn Zaddik has no scruple in combining (unconsciously,

to be sure) Platonic and Neo-Platonic psychology with the Aristotelian

definition representing quite a different point of view. The one is

anthropological dualism, regarding the soul as a distinct entity which

comes to the body from without. The other is a biological monism, in

which the soul is the reality of the body, the essence of its

functioning, which makes the potentially living body an actually living

body. We cannot enter here into a criticism of the elements of the

Aristotelian definition of the soul as rendered and interpreted by Ibn

Zaddik, but will merely say that it misses completely the meaning of

Aristotle, and shows that Ibn Zaddik did not take it from the "De Anima"

of Aristotle, but found it without its context in some Arabic work.

To return from our digression, the three souls, Ibn Zaddik tells us, are

spiritual powers; every one of them is a substance by itself of benefit

to the body. The rational soul gets the name soul primarily, and the

others get it from the rational soul. The _Intellect_ is called soul

because the rational soul and the Intellect have a common matter. And

hence when the soul is perfected it becomes intellect. This is why the

rational soul is called potential intellect. The only difference between

them is one of degree and excellence. The world of Intellect is

superior, and its matter is the pure light, Intellect in which there is

no ignorance, because it comes from God without any intermediate agency.

Here we see just a touch of the Neo-Platonic doctrine of emanation, of

which the Universal Intellect is the first. But it is considerably toned

down and not continued down the series as in Plotinus or the Brethren of

Purity.

The accidents of the soul are spiritual like the soul itself. They are,

knowledge, kindness, goodness, justice, and other similar qualities.

Ignorance, wrong, evil, and so on, are not the opposites of those

mentioned above, and were not created with the soul like the others.

They are merely the absence of the positive qualities mentioned before,

as darkness is the absence of light. God did not create any defect, nor

did he desire it. Evil is simply the result of the incapacity of a given

thing to receive a particular good. If all things were capable of

receiving goods equally, all things would be one thing, and the Creator

and his creatures would be likewise one. This was not God's purpose.

There is a tacit opposition to the Mutakallimun in Ibn Zaddik's

arguments against the view that the soul is an accident, as well as in

his statement in the preceding paragraph that the bad qualities and evil

generally are not opposites of the good qualities and good respectively,

but that they are merely privations, absences, and hence not created by

God. This is a Neo-Platonic doctrine. Pseudo-Bahya, we have seen (p. 108

f.), and Abraham bar Hiyya (p. 123 f.) adopt the Kalamistic view in the

latter point, and solve the problem of evil differently.

The function of the rational soul is knowledge. The rational soul

investigates the unknown and comprehends it. It derives general rules,

makes premises and infers one thing from another. Man alone has this

privilege. It is in virtue of the rational soul that we have been given

commandments and prohibitions, and become liable to reward and

punishment. Brute animals have no commandments, because they have no

reason. The soul has reason only potentially, and man makes it actual by

study. If the reason were actual originally in the soul, there would be

no difference between the soul's condition in its own world and in this

one; and the purpose of man, which is that he may learn in order to

choose the right way and win salvation, would have no meaning.

The existence of many individual souls, all of which have the soul

character in common, shows that there is a universal soul by virtue of

which all the particular souls exist. This division of the universal

soul into many individual souls is not really a division of the former

in its essence, which remains one and indivisible. It is the bodies

which receive the influence of the universal soul, as vessels in the sun

receive its light according to their purity. Hence the existence of

justice and evil, righteousness and wrong. This does not, however, mean

to say that the reception of these qualities is independent of a man's

choice. Man is free to choose, and hence he deserves praise and blame,

reward and punishment.

The rational soul is destined for the spiritual world, which is a pure

and perfect world, made by God directly without an intermediate agency.

It is not subject to change or defect or need. God alone created this

spiritual world to show his goodness and power, and not because he

needed it. The world is not like God, though God is its cause. It is not

eternal _a parte ante_, having been made out of nothing by God; but it

will continue to exist forever, for it cannot be more perfect than it

is. It is simple and spiritual. This applies also to the heavenly

spheres and their stars.

Man is obliged to reason and investigate, as all nations do according to

the measure of their capacities. No animal reasons because it has not

the requisite faculty. But if man should neglect to exercise the power

given him, he would lose the benefit coming therefrom and the purpose of

his existence. There would then be no difference between him and the

beast.

The first requisite for study and investigation is to deaden the animal

desires. Then with the reason as a guide and his body as a model, man

acquires the knowledge of the corporeal world. From his rational soul he

comes to the knowledge of the existence of a spiritual world. Finally he

will learn to know the Creator, who is the only real existent, for

nothing can be said truly to exist, which at one time did not exist, or

which at some time will cease to exist. When a man neglects this

privilege which is his of using his reason, he forfeits the name man,

and descends below the station of the beast, for the latter never falls

below its animal nature.

It is very important to study the knowledge of God, for it is the

highest knowledge and the cause of human perfection. The prophets are

full of recommendations in this regard. Jeremiah says (31, 33), "They

shall all know me, from the least of them even unto their greatest."

Amos (5, 6) bids us "Seek for the Lord and you shall live." Hosea

likewise (6, 3) recommends that "We may feel it, and strive to know the

Lord."[173]

The first loss a man suffers who does not study and investigate is that

he does not understand the real existence of God, and imagines he is

worshipping a body. Some think God is light. But this is as bad as to

regard him body. For light is an accident in a shining body, as is

proved by the fact that the air receives the light of the sun, and later

it receives the shadow and becomes dark. And yet these people are not

the worst by any means, for there are others who do not trouble to

concentrate their minds on God, and occupy their thoughts solely with

the business and the pleasures of this world. These people we do not

discuss at all. We are arguing against those who imagine they are wise

men and students of the Kalam. In fact they are ignorant persons, and do

not know what logic is and how it is to be used.

Before giving our own views of the nature and existence of God, we must

refute the objectionable doctrines of these people. Joseph al-Basir in a

work of his called "Mansuri" casts it up to the Rabbanites that in

believing that God descends and ascends they are not true worshippers of

God. But he forgets that his own doctrines are no better. Anyone who

believes that God created with a newly created will and rejects by means

of a newly created rejection has never truly served God or known him.

Just as objectionable is their view that God is living but not with life

residing in a subject, powerful but not with power, and so on. We shall

take up each of these in turn.

The Mutakallimun refuse to believe that God's will is eternal, for fear

of having a second eternal beside God. And so they say that whenever God

wills, he creates a will for the purpose, and whenever he rejects

anything he creates a "rejection" with which the objectionable thing is

rejected. But this leads them to a worse predicament than the one from

which they wish to escape, as we shall see. If God cannot create

anything without having a will as the instrument in creating, and for

this reason must first create a will for the purpose--how did he create

this will? He must have had another will to create this will, and a

third will to create the second, and so on _ad infinitum_, which is

absurd. If he created the first will without the help of another will,

why not create the things he wanted outright without any will? Besides,

in making God will at a given time after a state of not willing, they

introduce change in God.

As for the other dictum, that God is "living but not with life,"

"powerful but not with power," "knowing but not with knowledge," and so

on; what do they mean by this circumlocution? If they say "living" to

indicate that he is not dead, and add "but not with life," so as to

prevent a comparison of him with other living things, why not say also,

"He is body, but not like other bodies"? If the objection to calling him

body is that body is composite, and what is composite must have been

composed by someone and is not eternal, the same objection applies to

"living." For "living" implies "breathing" and "possessed of sensation,"

hence also composite and created. If they reply, we mean life peculiar

to him, we say why not also body peculiar to him? You see these people

entangle themselves in their own sophisms, because they do not know what

demonstration means.[174]

Having disposed of the errors of the Mutakallimun, we must now present

our own method of investigation into the nature of God. To know a thing,

we investigate its four causes--material, formal, efficient and final.

What has no cause but is the cause of all things, cannot be known in

this way. Still it is not altogether unknowable for this reason. Its

essence cannot be known, but it may be known through its activities, or

rather effects, which suggest attributes. We cannot therefore know

concerning God _what_ he is, nor _how_ he is, nor _on account of what_,

nor _of what kind_, nor _where_, nor _when_. For these can apply only to

a created thing having a cause. But we can ask concerning him, _whether_

he is; and this can best be known from his deeds.

We observe the things of the world and find that they are all composed

of substance and accident, as we saw before (p. 131). These are

correlative, and one cannot exist without the other. Hence neither

precedes the other. But accident is "new" (_i. e._, not eternal), hence

so is substance. That accident is new is proved from the fact that rest

succeeds motion and motion succeeds rest, hence accidents constantly

come and go and are newly created.

Now if substance and accident are both new there must be something that

brought them into being unless they bring themselves into being. But the

latter is impossible, for the agent must either exist when it brings

itself into being, or not. If it exists it is already there; if it does

not exist, it is nothing, and nothing cannot do anything. Hence there

must be a being that brought the world into existence. This is God.

God is one, for the cause of the many must be the one. If the cause of

the many is the many, then the cause of the second many is a third many,

and so on _ad infinitum_; hence we must stop with the one. God is to the

world as unity is to number. Unity is the basis of number without being

included in number, and it embraces number on all sides. It is the

foundation of number; for if you remove unity, you remove number; but

the removal of number does not remove unity. The one surrounds number on

all sides; for the beginning of number is the one, and it is also the

middle of number and the end thereof. For number is nothing but an

aggregate of ones. Besides, number is composed of odds and evens, and

one is the cause of odd as well as even.

If there were two eternal beings, they would either coincide in all

respects, and they would be one and not two. Or they would differ. In

the latter case, the world is either the work of both or of one only.

If of both, they are not omnipotent, and hence not eternal. If of one

only, then the other does not count, since he is not eternal, and there

is only one.

By saying God is one we do not mean that he comes under the category of

quantity, for quantity is an accident residing in a substance, and all

substance is "new." What we mean is that the essence of God is true

unity, not numerical unity. For numerical unity is also in a sense

multiplicity, and is capable of multiplication and division. God's unity

is alone separate and one in all respects.

God is not like any of his creatures. For if he were, he would be

possessed of quality, since it is in virtue of quality that a thing is

said to be like another, and quality is an accident contained in a

substance.

God is self-sufficient and not in need of anything. For if he needed

anything at all, it would be first of all the one who created him and

made him an existent thing. But this is absurd, since God is eternal. We

might suppose that he needs the world, which he created for some

purpose, as we sometimes make things to assist us. But this, too, is

impossible. For if he were dependent upon the world for anything, he

could not create it. It is different with us. We do not create things;

we only modify matter already existing.

Again, if God created the world for his own benefit, then either he was

always in need of the world, or the need arose at the time of creating.

If he was always in need of the world, it would have existed with him

from eternity, but we have already proved that the world is not eternal.

If the need arose in him at the time of creation, as heat arises in a

body after cold, or motion after rest, then he is like created things,

and is himself "new" and not eternal. To say the need was always there,

and yet he did not create it until the time he did would be to ascribe

inability to God of creating the world before he did, which is absurd.

For one who is unable at any given time, cannot create at all. It

remains then that he does not need anything, and that he created the

world by reason of his goodness and generosity and nothing else.

The question of God's will is difficult. The problem is this. If God's

will is eternal and unchanging, and he created the world with his will,

the world is eternal. If we say, as we must, that he created the world

after a condition of non-creation, we introduce a change in God, a

something newly created in him, namely, the will to create, which did

not exist before. This is a dilemma. My own view is that since God's

creating activity is his essence, and his essence is infinite and

eternal, we cannot say he created _after_ a condition of non-creation,

or that he willed _after_ a condition of non-willing, or that he was

formerly not able. And yet we do not mean that the world is eternal. It

was created a definite length of time before our time. The solution of

the problem is that time itself was created with the world; for time is

the measure of motion of the celestial sphere, and if there are no

spheres there is no time, and no before and after. Hence it does not

follow because the world is not eternal that _before_ its creation God

did not create. There is no _before_ when the world is not.

We objected to the view of the Mutakallimun (p. 142), who speak of God

creating a will on the ground that if he can create a will directly he

can create the world instead. Our opinion is therefore that God's will

is eternal and not newly created, for the latter view introduces

creation in God. There is still the difficulty of the precise relation

of the will to God. If it is different from God we have two eternals,

and if it is the same as God in all respects, he changes when he

creates. My answer is, it is not different from God in any sense, and

there is no changing attribute in God. But there is a subtle mystery in

this matter, which it is not proper to reveal, and this is not the place

to explain it. The interested reader is referred to the book of

Empedocles and other works of the wise men treating of this subject

(_cf._ above, p. 64).

God created the world out of nothing, and not out of a pre-existent

matter. For if the matter of the world is eternal like God, there is no

more reason for supposing that God formed a world out of it than that it

formed a world out of God.

The world is perfect. For we have repeatedly shown that its creation is

due entirely to God's goodness. If then it were not perfect, this would

argue in God either ignorance or niggardliness or weakness.[175]

Most of the ancients avoided giving God attributes for fear of making

him the bearer of qualities, which would introduce plurality and

composition in his essence. The proper view, however, is this. As God's

essence is different from all other essences, so are his attributes

different from all other attributes. His attributes are not different

from him; his knowledge and his truth and his power are his essence. The

way man arrives at the divine attributes is this. Men have examined his

works and learned from them God's existence. They then reflected on this

existent and found that he was not weak; so they called him strong. They

found his works perfect, and they called him wise. They perceived that

he was self-sufficient, without need of anything, and hence without any

motives for doing wrong. Hence they called him righteous. And so on with

the other attributes. All this they did in order that people may learn

from him and imitate his ways. But we must not forget that all these

expressions of God's attributes are figurative. No one must suppose that

if we do not say he has life, it means he is dead. What we mean is that

we cannot apply the term living to God literally, in the sense in which

we apply it to other living things. When the Bible does speak of God as

alive and living, the meaning is that he exists forever. The philosopher

is right when he says that it is more proper to apply negative

attributes to God than positive.[176]

Taking a glance at Ibn Zaddik's theology just discussed in its essential

outlines, we notice that while he opposes vigorously certain aspects of

Kalamistic thought, as he found them in al-Basir, the Karaite, his own

method and doctrine are not far removed from the Kalam. His proof of the

creation of the world from its composite character (substance and

accident) is the same as one of Saadia, which Maimonides cites as a

Kalamistic proof. We have already spoken of the fact that the method of

basing one's theology upon the creation of the world is one that is

distinctive of the Kalam, as Maimonides himself tells us. And this

method is common to Saadia, Bahya and Ibn Zaddik. In his discussion of

the attributes Ibn Zaddik offers little if anything that is new. His

attitude is that in the literal and positive sense no attribute can be

applied to God. We can speak of God negatively without running the risk

of misunderstanding. But the moment we say anything positive we do

become thus liable to comparing God with other things; and such

circumlocutions as the Kalamistic "Living without life," and so on, do

not help matters, for they are contradictory, and take away with one

hand what they give with the other. The Biblical expressions must be

taken figuratively; and the most important point to remember is that

God's essence cannot be known at all. The manner in which we arrive at

the divine attributes is by transferring them from God's effects in

nature to his own essence. All this we have already found in Bahya much

better expressed, and Bahya is also without doubt the source of Ibn

Zaddik's discussion of God's unity.

We must now review briefly the practical part of Ibn Zaddik's philosophy

as it is found in the fourth part of the "Microcosm." In the manner of

Bahya he points out the importance of divine service and obedience to

the commandments of God, viewing man's duties to his maker as an

expression of gratitude, which everyone owes to his benefactor. Like

Bahya he compares God's benefactions with those of one man to another to

show the infinite superiority of the former, and the greater duty which

follows therefrom.

The commandments which God gave us like the act of our creation are for

our own good, that we may enjoy true happiness in the world to come. As

it would not be proper to reward a person for what he has not done, God

gave man commandments. The righteous as well as the wicked are free to

determine their own conduct, hence reward and punishment are just.

Like Saadia and Bahya before him, Ibn Zaddik makes use of the

distinction (or rather takes it for granted) between rational and

traditional commandments; pointing out that the latter also have a cause

and explanation in the mind of God even though we may not know it. In

some cases we can see the explanation ourselves. Take for instance the

observance of the Sabbath. Its rational signification is two-fold. It

teaches us that the world was created, and hence has a Creator whom we

worship. And in the second place the Sabbath symbolizes the future

world. As one has nothing to eat on the Sabbath day unless he has

prepared food the day before, so the enjoyment of the future world

depends upon spiritual preparation in this world.

In his conduct a man must imitate God's actions by doing good and mercy

and kindness. Without the knowledge of God a person's good deeds are of

no account and no better than the work of idolaters. In fact it is not

possible to do good deeds without a knowledge of God, for he is the

source of all good, and there is no true good without him. When a fool

is seen with good qualities such as mercy and benevolence, they are due

to the weakness of his animal soul, the spirited part of his nature.

Similarly if this fool abstains from pleasures, it is because of the

weakness of his appetitive soul.

Thus we see that knowledge comes first in importance; for knowledge

leads to practice, and practice brings reward in the world to come. As

the purpose of man's creation is that he may enjoy the future life,

wisdom or knowledge is the first requisite to this great end.

The four principal qualities constituting goodness or virtue are (1)

knowledge of God's attributes; (2) righteousness or justice; (3) hope;

(4) humility. All other good qualities are derived from these. Jeremiah

names some of them when he says (9, 23), "I am the Lord who exercise

kindness, justice and righteousness on the earth; for in these things I

delight, saith the Lord." Similarly Zephaniah (2, 3) bids us, "Seek ye

the Lord, all ye meek of the earth, who have fulfilled his ordinances;

seek righteousness, seek meekness."

The four qualities of wisdom or knowledge, righteousness, hope and

humility are without doubt modified descendants of the four Platonic

virtues, wisdom, courage, temperance and justice, which we still find in

their original form and in their Platonic derivation and psychological

origin in Pseudo-Bahya (_cf._ above p. 111).

Reward and punishment of the real kind, Ibn Zaddik thinks, are not in

this world but in the next. In this way he accounts for the fact of the

prosperity of the wicked and the sufferings of the righteous. Another

proof that this world cannot be the place of final reward and punishment

is that pleasure in this world is not a real good, but only a temporary

respite from disease. Pain and pleasure are correlative, as we saw

before (p. 136). In fact pleasure is not a good at all; for if it were,

then the greater the pleasure, the greater the good, which is not true.

Reward in the next world is not a corporeal pleasure at all.

The evil which happens to the righteous in this world is often a natural

occurrence without reference to reward and punishment, and may be

compared to the natural pleasures which men derive from the sense of

sight and the other senses, and which have nothing to do with reward and

punishment. Sometimes, too, this evil is inflicted upon the good man to

forgive his sins. Real reward and punishment are in the future life,

and as that life is spiritual, the reward as well as the punishment is

timeless.

The Mutakallimun think that animals and little children are also

rewarded in the next world for ill treatment, suffering and death which

are inflicted upon them in this world. So we find in Joseph al Basir's

Mansuri. But this is absurd. If the killing of animals is a wrong, God

would not have commanded us to do it, any more than he ordered us to

kill human beings in order that he may reward them later. Moreover, we

should then deserve punishment for killing animals if that is wrong, and

there would follow the absurdity that God commanded us to do that for

which we deserve punishment. Besides, if the animals deserve reward and

punishment, they should have been given commandments and laws like

ourselves. If this was not done because animals are not rational, reward

and punishment are equally out of place for the same reason.

When the soul leaves the body in death, if she exercised her reason in

the pursuit of knowledge, she will continue her existence forever in the

upper world. This is her happiness, her reward and her paradise, namely,

to cleave to her own world, and to shine with the true light emanating

from God directly. This is the end of the human soul. But if she did not

exercise her reason and did not pursue right conduct, she will not be

able to return to the spiritual world, for she will have lost her own

spirituality. She will be similar to the body, desiring this world and

its pleasures. Her fate will be to revolve forever with the sphere in

the world of fire, without being able to return to her world. Thus she

will be forever in pain, and homeless.

When the Messiah comes, the pious men of our nation, the Prophets, the

Patriarchs and those who died for the sanctification of the name, _i. e._,

the martyrs, will be brought back to life in the body, and will

never die again. There will be no eating and drinking, but they will

live like Moses on the mountain basking in the divine light. The wicked

will also be joined to their bodies and burned with fire.[177]
