Section 3.

Plato’s account of the soul is partly mythical or figurative, and

partly literal. Not that either he or we can draw a line between

them, or say, ‘This is poetry, this is philosophy’; for the

transition from the one to the other is imperceptible. Neither

must we expect to find in him absolute consistency. He is apt to

pass from one level or stage of thought to another without always

making it apparent that he is changing his ground. In such

passages we have to interpret his meaning by the general spirit

of his writings. To reconcile his inconsistencies would be

contrary to the first principles of criticism and fatal to any

true understanding of him.

There is a further difficulty in explaining this part of the

Timaeus—the natural order of thought is inverted. We begin with

the most abstract, and proceed from the abstract to the concrete.

We are searching into things which are upon the utmost limit of

human intelligence, and then of a sudden we fall rather heavily

to the earth. There are no intermediate steps which lead from one

to the other. But the abstract is a vacant form to us until

brought into relation with man and nature. God and the world are

mere names, like the Being of the Eleatics, unless some human

qualities are added on to them. Yet the negation has a kind of

unknown meaning to us. The priority of God and of the world,

which he is imagined to have created, to all other existences,

gives a solemn awe to them. And as in other systems of theology

and philosophy, that of which we know least has the greatest

interest to us.

There is no use in attempting to define or explain the first God

in the Platonic system, who has sometimes been thought to answer

to God the Father; or the world, in whom the Fathers of the

Church seemed to recognize ‘the firstborn of every creature.’ Nor

need we discuss at length how far Plato agrees in the later

Jewish idea of creation, according to which God made the world

out of nothing. For his original conception of matter as

something which has no qualities is really a negation. Moreover

in the Hebrew Scriptures the creation of the world is described,

even more explicitly than in the Timaeus, not as a single act,

but as a work or process which occupied six days. There is a

chaos in both, and it would be untrue to say that the Greek, any

more than the Hebrew, had any definite belief in the eternal

existence of matter. The beginning of things vanished into the

distance. The real creation began, not with matter, but with

ideas. According to Plato in the Timaeus, God took of the same

and the other, of the divided and undivided, of the finite and

infinite, and made essence, and out of the three combined created

the soul of the world. To the soul he added a body formed out of

the four elements. The general meaning of these words is that God

imparted determinations of thought, or, as we might say, gave law

and variety to the material universe. The elements are moving in

a disorderly manner before the work of creation begins; and there

is an eternal pattern of the world, which, like the ‘idea of

good,’ is not the Creator himself, but not separable from him.

The pattern too, though eternal, is a creation, a world of

thought prior to the world of sense, which may be compared to the

wisdom of God in the book of Ecclesiasticus, or to the ‘God in

the form of a globe’ of the old Eleatic philosophers. The

visible, which already exists, is fashioned in the likeness of

this eternal pattern. On the other hand, there is no truth of

which Plato is more firmly convinced than of the priority of the

soul to the body, both in the universe and in man. So

inconsistent are the forms in which he describes the works which

no tongue can utter—his language, as he himself says, partaking

of his own uncertainty about the things of which he is speaking.

We may remark in passing, that the Platonic compared with the

Jewish description of the process of creation has less of freedom

or spontaneity. The Creator in Plato is still subject to a

remnant of necessity which he cannot wholly overcome. When his

work is accomplished he remains in his own nature. Plato is more

sensible than the Hebrew prophet of the existence of evil, which

he seeks to put as far as possible out of the way of God. And he

can only suppose this to be accomplished by God retiring into

himself and committing the lesser works of creation to inferior

powers. (Compare, however, Laws for another solution of the

difficulty.)

Nor can we attach any intelligible meaning to his words when he

speaks of the visible being in the image of the invisible. For

how can that which is divided be like that which is undivided? Or

that which is changing be the copy of that which is unchanging?

All the old difficulties about the ideas come back upon us in an

altered form. We can imagine two worlds, one of which is the mere

double of the other, or one of which is an imperfect copy of the

other, or one of which is the vanishing ideal of the other; but

we cannot imagine an intellectual world which has no qualities—‘a

thing in itself’—a point which has no parts or magnitude, which

is nowhere, and nothing. This cannot be the archetype according

to which God made the world, and is in reality, whether in Plato

or in Kant, a mere negative residuum of human thought.

There is another aspect of the same difficulty which appears to

have no satisfactory solution. In what relation does the

archetype stand to the Creator himself? For the idea or pattern

of the world is not the thought of God, but a separate,

self-existent nature, of which creation is the copy. We can only

reply, (1) that to the mind of Plato subject and object were not

yet distinguished; (2) that he supposes the process of creation

to take place in accordance with his own theory of ideas; and as

we cannot give a consistent account of the one, neither can we of

the other. He means (3) to say that the creation of the world is

not a material process of working with legs and arms, but ideal

and intellectual; according to his own fine expression, ‘the

thought of God made the God that was to be.’ He means (4) to draw

an absolute distinction between the invisible or unchangeable

which is or is the place of mind or being, and the world of sense

or becoming which is visible and changing. He means (5) that the

idea of the world is prior to the world, just as the other ideas

are prior to sensible objects; and like them may be regarded as

eternal and self-existent, and also, like the IDEA of good, may

be viewed apart from the divine mind.

There are several other questions which we might ask and which

can receive no answer, or at least only an answer of the same

kind as the preceding. How can matter be conceived to exist

without form? Or, how can the essences or forms of things be

distinguished from the eternal ideas, or essence itself from the

soul? Or, how could there have been motion in the chaos when as

yet time was not? Or, how did chaos come into existence, if not

by the will of the Creator? Or, how could there have been a time

when the world was not, if time was not? Or, how could the

Creator have taken portions of an indivisible same? Or, how could

space or anything else have been eternal when time is only

created? Or, how could the surfaces of geometrical figures have

formed solids? We must reply again that we cannot follow Plato in

all his inconsistencies, but that the gaps of thought are

probably more apparent to us than to him. He would, perhaps, have

said that ‘the first things are known only to God and to him of

men whom God loves.’ How often have the gaps in Theology been

concealed from the eye of faith! And we may say that only by an

effort of metaphysical imagination can we hope to understand

Plato from his own point of view; we must not ask for

consistency. Everywhere we find traces of the Platonic theory of

knowledge expressed in an objective form, which by us has to be

translated into the subjective, before we can attach any meaning

to it. And this theory is exhibited in so many different points

of view, that we cannot with any certainty interpret one dialogue

by another; e.g. the Timaeus by the Parmenides or Phaedrus or

Philebus.

The soul of the world may also be conceived as the

personification of the numbers and figures in which the heavenly

bodies move. Imagine these as in a Pythagorean dream, stripped of

qualitative difference and reduced to mathematical abstractions.

They too conform to the principle of the same, and may be

compared with the modern conception of laws of nature. They are

in space, but not in time, and they are the makers of time. They

are represented as constantly thinking of the same; for thought

in the view of Plato is equivalent to truth or law, and need not

imply a human consciousness, a conception which is familiar

enough to us, but has no place, hardly even a name, in ancient

Greek philosophy. To this principle of the same is opposed the

principle of the other—the principle of irregularity and

disorder, of necessity and chance, which is only partially

impressed by mathematical laws and figures. (We may observe by

the way, that the principle of the other, which is the principle

of plurality and variation in the Timaeus, has nothing in common

with the ‘other’ of the Sophist, which is the principle of

determination.) The element of the same dominates to a certain

extent over the other—the fixed stars keep the ‘wanderers’ of the

inner circle in their courses, and a similar principle of

fixedness or order appears to regulate the bodily constitution of

man. But there still remains a rebellious seed of evil derived

from the original chaos, which is the source of disorder in the

world, and of vice and disease in man.

But what did Plato mean by essence, (Greek), which is the

intermediate nature compounded of the Same and the Other, and out

of which, together with these two, the soul of the world is

created? It is difficult to explain a process of thought so

strange and unaccustomed to us, in which modern distinctions run

into one another and are lost sight of. First, let us consider

once more the meaning of the Same and the Other. The Same is the

unchanging and indivisible, the heaven of the fixed stars,

partaking of the divine nature, which, having law in itself,

gives law to all besides and is the element of order and

permanence in man and on the earth. It is the rational principle,

mind regarded as a work, as creation—not as the creator. The old

tradition of Parmenides and of the Eleatic Being, the foundation

of so much in the philosophy of Greece and of the world, was

lingering in Plato’s mind. The Other is the variable or changing

element, the residuum of disorder or chaos, which cannot be

reduced to order, nor altogether banished, the source of evil,

seen in the errors of man and also in the wanderings of the

planets, a necessity which protrudes through nature. Of this too

there was a shadow in the Eleatic philosophy in the realm of

opinion, which, like a mist, seemed to darken the purity of truth

in itself.—So far the words of Plato may perhaps find an

intelligible meaning. But when he goes on to speak of the Essence

which is compounded out of both, the track becomes fainter and we

can only follow him with hesitating steps. But still we find a

trace reappearing of the teaching of Anaxagoras: ‘All was

confusion, and then mind came and arranged things.’ We have

already remarked that Plato was not acquainted with the modern

distinction of subject and object, and therefore he sometimes

confuses mind and the things of mind—(Greek) and (Greek). By

(Greek) he clearly means some conception of the intelligible and

the intelligent; it belongs to the class of (Greek). Matter,

being, the Same, the eternal,—for any of these terms, being

almost vacant of meaning, is equally suitable to express

indefinite existence,—are compared or united with the Other or

Diverse, and out of the union or comparison is elicited the idea

of intelligence, the ‘One in many,’ brighter than any Promethean

fire (Phil.), which co-existing with them and so forming a new

existence, is or becomes the intelligible world...So we may

perhaps venture to paraphrase or interpret or put into other

words the parable in which Plato has wrapped up his conception of

the creation of the world. The explanation may help to fill up

with figures of speech the void of knowledge.

The entire compound was divided by the Creator in certain

proportions and reunited; it was then cut into two strips, which

were bent into an inner circle and an outer, both moving with an

uniform motion around a centre, the outer circle containing the

fixed, the inner the wandering stars. The soul of the world was

diffused everywhere from the centre to the circumference. To this

God gave a body, consisting at first of fire and earth, and

afterwards receiving an addition of air and water; because solid

bodies, like the world, are always connected by two middle terms

and not by one. The world was made in the form of a globe, and

all the material elements were exhausted in the work of creation.

The proportions in which the soul of the world as well as the

human soul is divided answer to a series of numbers 1, 2, 3, 4,

9, 8, 27, composed of the two Pythagorean progressions 1, 2, 4, 8

and 1, 3, 9, 27, of which the number 1 represents a point, 2 and

3 lines, 4 and 8, 9 and 27 the squares and cubes respectively of

2 and 3. This series, of which the intervals are afterwards

filled up, probably represents (1) the diatonic scale according

to the Pythagoreans and Plato; (2) the order and distances of the

heavenly bodies; and (3) may possibly contain an allusion to the

music of the spheres, which is referred to in the myth at the end

of the Republic. The meaning of the words that ‘solid bodies are

always connected by two middle terms’ or mean proportionals has

been much disputed. The most received explanation is that of

Martin, who supposes that Plato is only speaking of surfaces and

solids compounded of prime numbers (i.e. of numbers not made up

of two factors, or, in other words, only measurable by unity).

The square of any such number represents a surface, the cube a

solid. The squares of any two such numbers (e.g. 2 squared, 3

squared = 4, 9), have always a single mean proportional (e.g. 4

and 9 have the single mean 6), whereas the cubes of primes (e.g.

3 cubed and 5 cubed) have always two mean proportionals (e.g.

27:45:75:125). But to this explanation of Martin’s it may be

objected, (1) that Plato nowhere says that his proportion is to

be limited to prime numbers; (2) that the limitation of surfaces

to squares is also not to be found in his words; nor (3) is there

any evidence to show that the distinction of prime from other

numbers was known to him. What Plato chiefly intends to express

is that a solid requires a stronger bond than a surface; and that

the double bond which is given by two means is stronger than the

single bond given by one. Having reflected on the singular

numerical phenomena of the existence of one mean proportional

between two square numbers are rather perhaps only between the

two lowest squares; and of two mean proportionals between two

cubes, perhaps again confining his attention to the two lowest

cubes, he finds in the latter symbol an expression of the

relation of the elements, as in the former an image of the

combination of two surfaces. Between fire and earth, the two

extremes, he remarks that there are introduced, not one, but two

elements, air and water, which are compared to the two mean

proportionals between two cube numbers. The vagueness of his

language does not allow us to determine whether anything more

than this was intended by him.

Leaving the further explanation of details, which the reader will

find discussed at length in Boeckh and Martin, we may now return

to the main argument: Why did God make the world? Like man, he

must have a purpose; and his purpose is the diffusion of that

goodness or good which he himself is. The term ‘goodness’ is not

to be understood in this passage as meaning benevolence or love,

in the Christian sense of the term, but rather law, order,

harmony, like the idea of good in the Republic. The ancient

mythologers, and even the Hebrew prophets, had spoken of the

jealousy of God; and the Greek had imagined that there was a

Nemesis always attending the prosperity of mortals. But Plato

delights to think of God as the author of order in his works,

who, like a father, lives over again in his children, and can

never have too much of good or friendship among his creatures.

Only, as there is a certain remnant of evil inherent in matter

which he cannot get rid of, he detaches himself from them and

leaves them to themselves, that he may be guiltless of their

faults and sufferings.

Between the ideal and the sensible Plato interposes the two

natures of time and space. Time is conceived by him to be only

the shadow or image of eternity which ever is and never has been

or will be, but is described in a figure only as past or future.

This is one of the great thoughts of early philosophy, which are

still as difficult to our minds as they were to the early

thinkers; or perhaps more difficult, because we more distinctly

see the consequences which are involved in such an hypothesis.

All the objections which may be urged against Kant’s doctrine of

the ideality of space and time at once press upon us. If time is

unreal, then all which is contained in time is unreal—the

succession of human thoughts as well as the flux of sensations;

there is no connecting link between (Greek) and (Greek). Yet, on

the other hand, we are conscious that knowledge is independent of

time, that truth is not a thing of yesterday or tomorrow, but an

‘eternal now.’ To the ‘spectator of all time and all existence’

the universe remains at rest. The truths of geometry and

arithmetic in all their combinations are always the same. The

generations of men, like the leaves of the forest, come and go,

but the mathematical laws by which the world is governed remain,

and seem as if they could never change. The ever-present image of

space is transferred to time—succession is conceived as

extension. (We remark that Plato does away with the above and

below in space, as he has done away with the absolute existence

of past and future.) The course of time, unless regularly marked

by divisions of number, partakes of the indefiniteness of the

Heraclitean flux. By such reflections we may conceive the Greek

to have attained the metaphysical conception of eternity, which

to the Hebrew was gained by meditation on the Divine Being. No

one saw that this objective was really a subjective, and involved

the subjectivity of all knowledge. ‘Non in tempore sed cum

tempore finxit Deus mundum,’ says St. Augustine, repeating a

thought derived from the Timaeus, but apparently unconscious of

the results to which his doctrine would have led.

The contradictions involved in the conception of time or motion,

like the infinitesimal in space, were a source of perplexity to

the mind of the Greek, who was driven to find a point of view

above or beyond them. They had sprung up in the decline of the

Eleatic philosophy and were very familiar to Plato, as we gather

from the Parmenides. The consciousness of them had led the great

Eleatic philosopher to describe the nature of God or Being under

negatives. He sings of ‘Being unbegotten and imperishable,

unmoved and never-ending, which never was nor will be, but always

is, one and continuous, which cannot spring from any other; for

it cannot be said or imagined not to be.’ The idea of eternity

was for a great part a negation. There are regions of speculation

in which the negative is hardly separable from the positive, and

even seems to pass into it. Not only Buddhism, but Greek as well

as Christian philosophy, show that it is quite possible that the

human mind should retain an enthusiasm for mere negations. In

different ages and countries there have been forms of light in

which nothing could be discerned and which have nevertheless

exercised a life-giving and illumining power. For the higher

intelligence of man seems to require, not only something above

sense, but above knowledge, which can only be described as Mind

or Being or Truth or God or the unchangeable and eternal element,

in the expression of which all predicates fail and fall short.

Eternity or the eternal is not merely the unlimited in time but

the truest of all Being, the most real of all realities, the most

certain of all knowledge, which we nevertheless only see through

a glass darkly. The passionate earnestness of Parmenides

contrasts with the vacuity of the thought which he is revolving

in his mind.

Space is said by Plato to be the ‘containing vessel or nurse of

generation.’ Reflecting on the simplest kinds of external

objects, which to the ancients were the four elements, he was led

to a more general notion of a substance, more or less like

themselves, out of which they were fashioned. He would not have

them too precisely distinguished. Thus seems to have arisen the

first dim perception of (Greek) or matter, which has played so

great a part in the metaphysical philosophy of Aristotle and his

followers. But besides the material out of which the elements are

made, there is also a space in which they are contained. There

arises thus a second nature which the senses are incapable of

discerning and which can hardly be referred to the intelligible

class. For it is and it is not, it is nowhere when filled, it is

nothing when empty. Hence it is said to be discerned by a kind of

spurious or analogous reason, partaking so feebly of existence as

to be hardly perceivable, yet always reappearing as the

containing mother or nurse of all things. It had not that sort of

consistency to Plato which has been given to it in modern times

by geometry and metaphysics. Neither of the Greek words by which

it is described are so purely abstract as the English word

‘space’ or the Latin ‘spatium.’ Neither Plato nor any other Greek

would have spoken of (Greek) or (Greek) in the same manner as we

speak of ‘time’ and ‘space.’

Yet space is also of a very permanent or even eternal nature; and

Plato seems more willing to admit of the unreality of time than

of the unreality of space; because, as he says, all things must

necessarily exist in space. We, on the other hand, are disposed

to fancy that even if space were annihilated time might still

survive. He admits indeed that our knowledge of space is of a

dreamy kind, and is given by a spurious reason without the help

of sense. (Compare the hypotheses and images of Rep.) It is true

that it does not attain to the clearness of ideas. But like them

it seems to remain, even if all the objects contained in it are

supposed to have vanished away. Hence it was natural for Plato to

conceive of it as eternal. We must remember further that in his

attempt to realize either space or matter the two abstract ideas

of weight and extension, which are familiar to us, had never

passed before his mind.

Thus far God, working according to an eternal pattern, out of his

goodness has created the same, the other, and the essence

(compare the three principles of the Philebus—the finite, the

infinite, and the union of the two), and out of them has formed

the outer circle of the fixed stars and the inner circle of the

planets, divided according to certain musical intervals; he has

also created time, the moving image of eternity, and space,

existing by a sort of necessity and hardly distinguishable from

matter. The matter out of which the world is formed is not

absolutely void, but retains in the chaos certain germs or traces

of the elements. These Plato, like Empedocles, supposed to be

four in number—fire, air, earth, and water. They were at first

mixed together; but already in the chaos, before God fashioned

them by form and number, the greater masses of the elements had

an appointed place. Into the confusion (Greek) which preceded

Plato does not attempt further to penetrate. They are called

elements, but they are so far from being elements (Greek) or

letters in the higher sense that they are not even syllables or

first compounds. The real elements are two triangles, the

rectangular isosceles which has but one form, and the most

beautiful of the many forms of scalene, which is half of an

equilateral triangle. By the combination of these triangles which

exist in an infinite variety of sizes, the surfaces of the four

elements are constructed.

That there were only five regular solids was already known to the

ancients, and out of the surfaces which he has formed Plato

proceeds to generate the four first of the five. He perhaps

forgets that he is only putting together surfaces and has not

provided for their transformation into solids. The first solid is

a regular pyramid, of which the base and sides are formed by four

equilateral or twenty-four scalene triangles. Each of the four

solid angles in this figure is a little larger than the largest

of obtuse angles. The second solid is composed of the same

triangles, which unite as eight equilateral triangles, and make

one solid angle out of four plane angles—six of these angles form

a regular octahedron. The third solid is a regular icosahedron,

having twenty triangular equilateral bases, and therefore 120

rectangular scalene triangles. The fourth regular solid, or cube,

is formed by the combination of four isosceles triangles into one

square and of six squares into a cube. The fifth regular solid,

or dodecahedron, cannot be formed by a combination of either of

these triangles, but each of its faces may be regarded as

composed of thirty triangles of another kind. Probably Plato

notices this as the only remaining regular polyhedron, which from

its approximation to a globe, and possibly because, as Plutarch

remarks, it is composed of 12 x 30 = 360 scalene triangles

(Platon. Quaest.), representing thus the signs and degrees of the

Zodiac, as well as the months and days of the year, God may be

said to have ‘used in the delineation of the universe.’ According

to Plato earth was composed of cubes, fire of regular pyramids,

air of regular octahedrons, water of regular icosahedrons. The

stability of the last three increases with the number of their

sides.

The elements are supposed to pass into one another, but we must

remember that these transformations are not the transformations

of real solids, but of imaginary geometrical figures; in other

words, we are composing and decomposing the faces of substances

and not the substances themselves—it is a house of cards which we

are pulling to pieces and putting together again (compare however

Laws). Yet perhaps Plato may regard these sides or faces as only

the forms which are impressed on pre-existent matter. It is

remarkable that he should speak of each of these solids as a

possible world in itself, though upon the whole he inclines to

the opinion that they form one world and not five. To suppose

that there is an infinite number of worlds, as Democritus

(Hippolyt. Ref. Haer. I.) had said, would be, as he satirically

observes, ‘the characteristic of a very indefinite and ignorant

mind.’

The twenty triangular faces of an icosahedron form the faces or

sides of two regular octahedrons and of a regular pyramid (20 = 8

x 2 + 4); and therefore, according to Plato, a particle of water

when decomposed is supposed to give two particles of air and one

of fire. So because an octahedron gives the sides of two pyramids

(8 = 4 x 2), a particle of air is resolved into two particles of

fire.

The transformation is effected by the superior power or number of

the conquering elements. The manner of the change is (1) a

separation of portions of the elements from the masses in which

they are collected; (2) a resolution of them into their original

triangles; and (3) a reunion of them in new forms. Plato himself

proposes the question, Why does motion continue at all when the

elements are settled in their places? He answers that although

the force of attraction is continually drawing similar elements

to the same spot, still the revolution of the universe exercises

a condensing power, and thrusts them again out of their natural

places. Thus want of uniformity, the condition of motion, is

produced. In all such disturbances of matter there is an

alternative for the weaker element: it may escape to its kindred,

or take the form of the stronger—becoming denser, if it be

denser, or rarer if rarer. This is true of fire, air, and water,

which, being composed of similar triangles, are interchangeable;

earth, however, which has triangles peculiar to itself, is

capable of dissolution, but not of change. Of the interchangeable

elements, fire, the rarest, can only become a denser, and water,

the densest, only a rarer: but air may become a denser or a

rarer. No single particle of the elements is visible, but only

the aggregates of them are seen. The subordinate species depend,

not upon differences of form in the original triangles, but upon

differences of size. The obvious physical phenomena from which

Plato has gathered his views of the relations of the elements

seem to be the effect of fire upon air, water, and earth, and the

effect of water upon earth. The particles are supposed by him to

be in a perpetual process of circulation caused by inequality.

This process of circulation does not admit of a vacuum, as he

tells us in his strange account of respiration.

Of the phenomena of light and heavy he speaks afterwards, when

treating of sensation, but they may be more conveniently

considered by us in this place. They are not, he says, to be

explained by ‘above’ and ‘below,’ which in the universal globe

have no existence, but by the attraction of similars towards the

great masses of similar substances; fire to fire, air to air,

water to water, earth to earth. Plato’s doctrine of attraction

implies not only (1) the attraction of similar elements to one

another, but also (2) of smaller bodies to larger ones. Had he

confined himself to the latter he would have arrived, though,

perhaps, without any further result or any sense of the greatness

of the discovery, at the modern doctrine of gravitation. He does

not observe that water has an equal tendency towards both water

and earth. So easily did the most obvious facts which were

inconsistent with his theories escape him.

The general physical doctrines of the Timaeus may be summed up as

follows: (1) Plato supposes the greater masses of the elements to

have been already settled in their places at the creation: (2)

they are four in number, and are formed of rectangular triangles

variously combined into regular solid figures: (3) three of them,

fire, air, and water, admit of transformation into one another;

the fourth, earth, cannot be similarly transformed: (4) different

sizes of the same triangles form the lesser species of each

element: (5) there is an attraction of like to like—smaller

masses of the same kind being drawn towards greater: (6) there is

no void, but the particles of matter are ever pushing one another

round and round (Greek). Like the atomists, Plato attributes the

differences between the elements to differences in geometrical

figures. But he does not explain the process by which surfaces

become solids; and he characteristically ridicules Democritus for

not seeing that the worlds are finite and not infinite.
