CHAPTER VII.

MATTER AND ITS RELATION TO SPIRIT.

Locke's account of innate ideas and of sensation is only preparatory

to a discussion of the ideas got by sensation. His explanation of the

mode of knowledge leads up to an explanation of the things known. He

remains true to his fundamental idea that before we come to conclusions

about any matters we must "examine our own ability." He deals first

with ideas got by the senses, whether by some one or by their conjoint

action. Of these the ideas of solidity, of extension, and of duration

are of most concern to us. They form as near an approach to a general

philosophy of nature as may be found anywhere in Locke. They are, too,

the germ from which grew the ideas of matter, of space, and of time,

which, however more comprehensive in scope and more amply worked out

in detail, characterize succeeding British thought, and which are

reproduced to-day by Mr. Spencer.

"The idea of solidity we receive by our touch." "The ideas we get

by more than one sense are of space or extension, figure, rest,

and motion." These sentences contain the brief statement of the chief

contention of the sensational school. Locke certainly was not conscious

when he wrote them that they were the expression of ideas which should

resolve the world of matter and of space into a dissolving series of

accidentally associated sensations; but such was none the less the

case. When he writes, "If any one asks me what solidity is, I send him

to his senses to inform him," he is preparing the way for Berkeley,

and for a denial of all reality beyond the feelings of the individual

mind. When he says that "we get the idea of space both by sight and

touch," this statement, although appearing truistic, is none the less

the source of the contention of Hume that even geometry contains

no necessary or universal elements, but is an account of sensible

appearances, relative, as are all matters of sensation.

Locke's ideas may be synopsized as follows: It is a sufficient account

of solidity to say that it is got by touch and that it arises from

the resistance found in bodies to the entrance of any other body. "It

is that which hinders the approach of two bodies when they are moved

towards one another." If not identical with matter, it is at all events

its most essential property. "This of all others seems the idea most

intimately connected with and essential to body, so as nowhere else

to be found or imagined, but only in matter." It is, moreover, the

source of the other properties of matter. "Upon the solidity of bodies

depend their mutual impulse, resistance, and protrusion." Solidity,

again, "is so inseparable an idea from body that upon that depends its

filling of space, its contact, impulse, and communication of motion

upon impulse." It is to be distinguished, therefore, from hardness, for

hardness is relative and derived, various bodies having various degrees

of it; while solidity consists in utter exclusion of other bodies from

the space possessed by any one, so that the hardest body has no more

solidity than the softest.

The close connection between solidity and matter makes it not only

possible, but necessary, to distinguish between matter and extension as

against the Cartesians, who had identified them. In particular Locke

notes three differences between these notions. Extension includes

neither solidity nor resistance; its parts are inseparable from one

another both really and mentally, and are immovable; while matter has

solidity, its parts are mutually separable, and may be moved _in_

space. From this distinction between space and matter it follows,

according to Locke, that there is such a thing as a vacuum, or that

space is not necessarily a plenum of matter. Matter is that which fills

space; but it is entirely indifferent to space whether or not it is

filled. Space is occupied by matter, but there is no essential relation

between them. Solidity is the essence of matter; emptiness is the

characteristic of space. "The idea of space is as distinct from that

of solidity as it is from that of scarlet color. It is true, solidity

cannot exist without extension, neither can scarlet color exist without

extension; but this hinders not that they are _distinct ideas_."

Thus there is fixed for us the idea of space as well as of matter. It

is a distinct idea; that is, absolute or independent in itself,

having no intrinsic connection with phenomena _in_ space. Yet it is

got through the senses. How that can be a matter of sensation which is

not only not material, but has no connection in itself with matter,

Locke does not explain. He thinks it sufficient to say that we see

distance between bodies of different color just as plainly as we see

the colors. Space is, therefore, a purely immediate idea, containing

no more organic relation to intelligence than it has to objects. We

get the notion of time as we do that of space, excepting that it is

the observation of internal states and not of external objects which

furnishes the material of the idea. Time has two elements,--succession

and duration. "Observing what passes in the mind, how of our ideas

there in train some constantly vanish, and others begin to appear,

we come by the idea of succession, and by observing a distance in

the parts of this succession we get the idea of duration." Whether,

however, time is something essentially empty, having no relation to the

events which fill it, as space is essentially empty, without necessary

connection with the objects which fill it, is a question Locke does not

consider. In fact, the gist of his ideas upon this point is as follows:

there is actually an objective space or pure emptiness; employing our

senses, we get the idea of this space. There is actually an objective

time; employing reflection, we perceive it. There is not the slightest

attempt to form a philosophy of them, or to show their function in the

construction of an intelligible world, except in the one point of the

absolute independence of matter and space.

It cannot be said that Leibniz criticises the minor points of Locke

in such a way as to throw much light upon them, or that he very

fully expresses his own ideas about them. He contents himself with

declaring that while the senses may give instances of space, time,

and matter, and may suggest to intelligence the stimuli upon which

intelligence realizes these notions from itself, they cannot be the

source of these notions themselves; finding the evidence of this in the

sciences of geometry, arithmetic, and pure physics. For these sciences

deal with the notions of space, time, and matter, giving necessary

and demonstrative ideas concerning them, which the senses can never

legitimate. He further denies the supposed absoluteness or independence

of space, matter, and motion. Admitting, indeed, the distinction

between extension and matter, he denies that this distinction suffices

to prove the existence, or even the possibility, of a vacuum, and ends

with a general reference to his doctrine of pre-established harmony,

as serving to explain these matters more fully and more accurately.

Leibniz has, however, a complete philosophy of nature. In his other

writing, he explains the ideas of matter and force in their dependence

upon his metaphysic, or doctrine of spiritual entelechies. The task

does not at first sight appear an easy one. The reality, according to

Leibniz, is purely spiritual, does not exist in space nor time, and

is a principle of activity following its own law,--that of reflecting

the universe of spiritual relations. How from this world of ideal,

unextended, and non-temporal dynamic realities we are to pass over to

a material world of extension, with its static existence in space,

and transitory passage in time, is a question challenging the whole

Leibnizian system. It is a question, however, for which Leibniz himself

has provided an answer. We may not regard it as adequate; we may think

that he has not truly derived the material world from his spiritual

principles: but at all events he asked himself the question, and gave

an answer. We shall investigate this answer by arranging what Leibniz

has said under the heads of: matter as a metaphysical principle; matter

as a physical phenomenon; and the relation of phenomena to absolute

reality, or of the physical to the metaphysical. In connection with the

second head, particularly, we shall find it necessary to discuss what

Leibniz has said about space, time, and motion.

Wolff, who put the ideas of Leibniz into systematic shape, did it at

the expense of almost all their significance. He took away the air

of paradox, of remoteness, that characterized Leibniz's thought, and

gave it a popular form. But its depth and suggestiveness vanished in

the process. Unfortunately, Wolff's presentations of the philosophy

of Leibniz have been followed by others, to whom it seemed a dull

task to follow out the intricacies of a thought nowhere systematically

expressed. This has been especially the case as concerns the Leibnizian

doctrine of matter. A superficial interpretation of certain passages

in Leibniz has led to an almost universal misunderstanding about

it. Leibniz frequently says that since matter is composite or complex,

it follows that there must be something simple as its basis, and this

simple something is the monad. The misinterpretation just spoken of

consists in supposing that Leibniz meant that matter as composite

is made up of monads as simple; that the monad and matter are facts

of the same order, the latter being only an aggregate, or continued

collection of the former. It interpreted the conception of Leibniz in

strict analogy with the atomic theory of Lucretius, excepting that it

granted that the former taught that the ultimate atom, the component

of all complex forms of matter, has position only, not extension,

its essence consisting in its exercise of force, not in its mere space

occupancy. The monad was thus considered to be _in_ space, or at least

conditioned by space relations, as is a mathematical point, although

not itself spatial in the sense of being extended. Monad and matter

were thus represented as facts of the same kind or genus, having their

difference only in their relative isolation or aggregation.

But Leibniz repudiated this idea, and that not only by the spirit

of his teaching, but in express words. Monads "are not ingredients

or constituents of matter," he says, "but only _conditions_

of it." "Monads can no more be said to be parts of bodies, or to

come in contact with them, or to compose them, than can souls or

mathematical points." "Monads _per se_ have _no_ situation relative

to one another." An increase in the number of created monads, he says

again, if such a thing could be supposed, would no more increase the

amount of matter in existence, than mathematical points added to a

line would increase its length. And again: "There is no nearness or

remoteness among monads; to say that they are gathered in a point or

are scattered in space, is to employ mental fictions, _in trying to

imagine what can only be thought_." The italicized words give the clew

to the whole discussion. To make monads of the same order as corporeal

phenomena, is to make them sensible, or capable of being imaged,

or conditioned by space and time,--three phrases which are strictly

correlative. But the monads can only be thought,--that is, their

qualities are ideal, not sensible; they can be realized only by reason,

not projected in forms having spatial outline and temporal habitation,

that is, in images. Monads and material things, in other words, are

facts of two distinct orders; they are related as the rational or

spiritual and the physical or sensible. Matter is no more composed of

monads than it is of thoughts or of logical principles. As Leibniz says

over and over again: Matter, space, time, motion are only phenomena,

although phenomena _bene fundata_,--phenomena, that is, having their

rational basis and condition. The monads, on the other hand, are not

appearances, they are realities.

Having freed our minds from the supposition that it is in any way

possible to form an image or picture of the monad; having realized that

it is wholly false to suppose that monads occupy position in space,

and then by their continuity fill it, and make extended matter,--we

must attempt to frame a correct theory of the nature of matter and

its relation to the monad. We shall do this only as we realize that

"matter," so far as it has any reality, or so far as it has any real

_fundamentum_, must be something ideal, or, in Leibniz's language,

"metaphysical." As he says over and over again, the only realities

are the substances or spiritual units of activity, to which the name

"monad" is given. In the inquiry, then, after such reality as matter

may have, we must betake ourselves to this unit of living energy.

Although every monad is active, it is not entirely active. There is,

as we have already seen, an infinite scale of substances; and since

substance is equivalent to activity, this is saying that there is an

infinite scale of activities. God alone is _purus actus_, absolute

energy, untouched by passivity or receptivity. Every other being has

the element of incompleteness, of inadequacy; it does not completely

represent the universe. In this passivity consists its finitude, so

that Leibniz says that not even God himself could deprive monads of it,

for this would be to make them equal to himself. In this passivity,

incompleteness, or finitude, consists what we call matter. Leibniz says

that he can understand what Plato meant when he called matter something

essentially imperfect and transitory. Every finite monad is a union of

two principles,--those of activity and of passivity. "I do not admit,"

says Leibniz, "that there are souls existing simply by themselves,

or that there are created spirits detached from all body. God alone is

above all matter, since he is its author; creatures freed from matter

would be at the same time detached from the universal connection

of things, and, as it were, deserters from the general order." And

again, "Beings have a nature which is both active and passive;

_that is_, material and immaterial." And again, he says that every

created monad requires both an entelechy, or principle of activity,

and matter. "Matter is essential to any entelechy, and can never be

separated from it, since matter _completes_ it." In short, the term

"monad" is equivalent to the term "entelechy" only when applied

to God. In every other monad, the entelechy, or energy, is but one

factor. "Matter, or primitive passive power, completes the entelechy,

or primitive active power, so that it becomes a perfect substance, or

monad." On the other hand, of course, matter, as the passive principle,

is a mere potentiality or abstraction, considered in itself. It is

real only in its union with the active principle. Matter, he says,

"cannot exist without immaterial substances." "To every particular

portion of matter belongs a particular _form_; that is, a soul,

a spirit." To this element of matter, considered as an abstraction,

in its distinction from soul, Leibniz, following the scholastics, and

ultimately Aristotle, gives the name, "first" or "bare" matter. The

same influence is seen in the fact that he opposes this element of

matter to "form," or the active principle.

Our starting-point, therefore, for the consideration of matter

is the statement that it is receptivity, the capacity for being

affected, which always constitutes matter. But what is meant by

"receptivity"? To answer this question we must return to what was said

about the two activities of the monad,--representation, or perception,

and appetition,--and to the difference between confused and distinct

ideas. The monad has appetition so far as it determines itself

from within to change, so far as it follows an internal principle

of energy. It is representative so far as it is determined from

without, so far as it receives impressions from the universe. Yet

we have learned to know that in one sense everything occurs from

the spontaneity of the monad itself; it receives no influence or

influxus from without; everything comes from its own depths, or is

appetition. But, on the other hand, all that which so comes forth is

only a mirroring or copying of the universe. The whole content of the

appetition is representation. Although the monad works spontaneously,

it is none the less determined in its activities to produce only

reflections or images of the world. In this way appetition and

representation appear to be identical. The monad is determined from

within, indeed, but it is determined to exactly the same results as if

wholly determined from without. What light, then, can be thrown from

this distinction upon the nature of matter?

None, unless we follow Leibniz somewhat farther. If we do, we shall

see that the soul is regarded as appetitive, or self-active, so far

as it has clear and distinct ideas. If the monad reaches distinct

consciousness, it has knowledge of self,--that is, of the nature of

pure spirit,--or, what again is equivalent to this, of the nature

of reality as it universally is. Such knowledge is knowledge of God,

of substance, of unity, of pure activity, and of all the innate ideas

which elevate the confused perceptions of sense into science. Distinct

consciousness is therefore equivalent to self-activity, and this to

recognition of God and the universal. But if knowledge is confused,

it is not possible to see it in its relations to self; it cannot

be analyzed; the rational or ideal element in it is concealed from

view. In confused ideas, therefore, the soul appears to be passive;

being passive, to be determined from without. This determination from

without is equivalent to that which is opposed to spirit or reason, and

hence appears as matter. Such is in outline the Leibnizian philosophy.

It thus is clear that merely stating that matter is passivity

in the monad is not the ultimate way of stating its nature. For

passivity means in reality nothing but confused representations,--representations,

that is, whose significance is not perceived. The true significance

of every representation is found in its relation to the

ego, or pure self-activity, which, through its dependent

relation upon God, the absolute self-activity and ego, produces

the representation from its own ideal being. So far as the

soul does not have distinct recognition of relation of all

representations to self, it feels them as coming from without; as

foreign to spirit; in short, as matter. Leibniz thus employs exactly

the same language about confused ideas that he does about passivity,

or matter. It is not possible that the monad should have distinct

consciousness of itself as a mirror of the whole universe, he says,

"for in that case every entelechy would be God." Again, "the soul would

be God if it could enter at once and with distinctness into everything

occurring within it." But it is necessary "that we should have

passions which consist in confused ideas, in which there is something

involuntary and unknown, and which represent the body and constitute

our imperfection." Again, he speaks of matter as "the _mixture_

(_mélange_) of the effects of the infinite environing us." In that

expression is summed up his whole theory of matter. It is a mixture;

it is, that is to say, confused, aggregated, irresolvable into simple

ideas. But it is a mixture of "effects of the infinite about us;"

that is, it takes its rise in the true, the real, the spiritual. It

only fails to represent this as it actually is. Matter, in short, is a

phenomenon dependent upon inability to realize the entire spiritual

character of reality. It is spirit apprehended in a confused,

hesitating, and passive manner.

It is none the less a necessary phenomenon, for it is involved in the

idea of a continuous gradation of monads, in the distinction between

the infinite and the finite, or, as Leibniz often prefers to put it,

between the "creator" and the "created." There is involved everywhere

in the idea of Leibniz the conception of subordination; of a hierarchy

of forms, each of which receives the law of its action from the

next higher, and gives the law to the next lower. We have previously

considered the element of passivity or receptivity as relating only

to the monad which manifests it. It is evident, however, that what

is passive in one, implies something active in another. What one

receives, is what another gives. The reciprocal influence of monads

upon one another, therefore, as harmonious members of one system,

requires matter. More strictly speaking, this reciprocal influence

_is_ matter. To take away all receptivity, all passivity, from monads

would be to isolate them from all relations with others; it would

be to deprive them of all power of affecting or being affected by

others. That is what Leibniz meant by the expression already quoted,

that if monads had not matter as an element in them, "they would be,

as it were, deserters from the general order." The note of unity, of

organic connection, which we found to be the essence of the Leibnizian

philosophy, absolutely requires, therefore, matter, or passivity.

It must be remembered that this reciprocal influence is ideal. As

Leibniz remarks, "When it is said that one monad is affected by

another, this is to be understood concerning its _representation_ of

the other. For the Author of things has so accommodated them to one

another that one is said to suffer (or receive from the other) when

its relative value gives way to that of the other." Or again, "the

modifications of one monad are the ideal causes of the modifications

of another monad, so far as there appear in one the reasons on account

of which God brought about in the beginning certain modifications in

another." And most definitely of all: "A creature is called active so

far as it has perfection; passive in so far as it is imperfect. One

creature is more perfect than another so far as there is found in

it that which serves to _render the reason_, _a priori_, for that

occurring in the other; and it is in this way that it acts upon the

other."

We are thus introduced, from a new point of view and in a more concrete

way, to the conception of pre-established harmony. The activity of one,

the energy which gives the law to the other and makes it subordinate in

the hierarchy of monads, is conceived necessarily as spirit, as soul;

that which receives, which is rendered subordinate by the activity

of the other, is body. The pre-established harmony is the fact that

they are so related that one can receive the law of its activity from

the other. Leibniz is without doubt partially responsible for the

ordinary misconception of his views upon this point by reason of the

illustration which he was accustomed to use; namely, of two clocks so

constructed that without any subsequent regulation each always kept

perfect time with the other,--as much so as if there were some actual

physical connection between them. This seems to put soul and body,

spirit and matter, as two co-ordinate substances, on the same level,

with such natural opposition between them that some external harmony

must arrange some unity of action. In causing this common idea of

his theory of pre-established harmony, Leibniz has paid the penalty

for attempting to do what he often reproves in others,--imagining or

presenting in sensible form what can only be thought. But his other

explanations show clearly enough that the pre-established harmony

expresses, not a relation between two parallel substances, but a

condition of dependence of lower forms of activity upon the higher for

the law of their existence and activity,--in modern terms, it expresses

the fact that phenomena are conditioned upon noumena; that material

facts get their significance and share of reality through their

relation to spirit.

We may sum up what has been said about matter as an element in the

monad, or as a metaphysical principle, as follows: The existence of

matter is not only not opposed to the fundamental ideas of Leibniz, but

is a necessary deduction from them. It is a necessity of the principle

of continuity; for this requires an infinity of monads, alike indeed

in the universal law of their being, but unlike, each to each, in

the specific coloring or manifestation of this law. The principle of

organic unity requires that there be as many real beings as possible

participating in and contributing to it. It is necessary, again, in

order that there may be reciprocal influence or connection among the

monads. Were it not for the material element in the monad, each would

be a God; if each were thus infinite and absolute, there would be

so many principles wholly independent and isolated. The principle of

harmony would be violated. So much for the necessity of the material

factor. As to its nature, it is a principle of passivity; that is, of

ideal receptivity, of conformity to a law apparently not self-imposed,

but externally laid down. This makes matter equivalent to a phenomenon;

that is to say, to the having of confused, imperfect, inadequate

ideas. To say that matter is correlative to confused ideas is to say

that there is no recognition of its relation to self or to spirit. As

Leibniz sometimes puts it, since there is an infinity of beings in

the universe, each one of which exercises an ideal influence upon

every other one of the series, it is impossible that this other one

should realize their full meaning; they appear only as confused ideas,

or as matter. To use language which Leibniz indeed does not employ,

but which seems to convey his thought, the spirit, not seeing them as

they really are, does not _find_ itself in them. But matter is thus not

only the confused manifestation or phenomenon of spirit, it is also its

potentiality. Passivity is always relative. It does not mean complete

lack of activity; that, as Leibniz says, is nothingness, and matter

is not a form of nothingness. Leibniz even speaks of it as passive

_power_. That is to say, there is an undeveloped or incomplete activity

in what appears as matter, and this may be,--if we admit an infinity

of time,--must be developed. When developed it manifests itself as it

really is, as spirit. Confused ideas, as Leibniz takes pains to state,

are not a genus of ideas antithetical to distinct; they differ only in

degree or grade. They are on their way to become distinct, or else they

are distinct ideas which have fallen back into an "involved" state of

being. Matter, therefore, is not absolutely opposed to spirit,--on the

one hand because it is the manifestation, the phenomenon, of spirit;

on the other, because it is the potentiality of spirit, capable of

sometime realizing the whole activity implied in it, but now latent.

Thus it is that Leibniz says that everything is "full" of souls or

monads. What appears to be lifeless is in reality like a pond full of

fishes, like a drop of water full of infusoria. Everything is organic

down to the last element. More truly, there is no last element. There

is a true infinity of organic beings wrapped up in the slightest speck

of apparently lifeless matter. These illustrations, like many others

which Leibniz uses, are apt to suggest that erroneous conception of the

relation of monads to spirit which we were obliged, in Leibniz's name,

to correct at the outset,--the idea, namely, that matter is composed,

in a spatial or mechanical way, of monads. But after the foregoing

explanations we can see that what Leibniz means when he says that

every portion of matter is full of entelechies or souls, like a garden

full of plants, is that there is an absolute continuity of spiritual

principles, each having its ideal relation with every other. There

is no point of matter which does not represent in a confused way the

entire universe. It is therefore as infinite in its activities as

the universe. In idea also it is capable of representing in distinct

consciousness, or as a development of its own self-activity, each of

these infinite activities.

In a word, every created or finite being may be regarded as matter or

as spirit, according as it is accounted for by its external relations,

as the reasons for what happen in it are to be found elsewhere than in

its own explicit activity, or according as it shows clearly in itself

the reasons for its own modifications, and also accounts for changes

occurring in other beings. The externally conditioned is matter;

the internally conditioned, the self-explanatory, is self-active, or

spirit. Since all external relations are finally dependent on organic;

since the ultimate source of all explanation must be that which is

its own reason; since the ultimate source of all activity must be that

which is self-active,--the final reason or source of matter is spirit.
