later on called materialism, which makes the corporeal alone to be the substantial, admitting nothing to have reality excepting what can be laid hold of by the hand, such as rocks and oaks. “Let us,” says Plato, in the second place, “proceed to the other, to the friends of Ideas.” Their belief is that the substantial is incorporeal, intellectual, and they separate from it the region of Becoming, of change, into which the sensuous falls, while the universal is for itself. These represent Ideas as immovable, and neither active nor passive. Plato asserts, as against this, that movement, life, soul, and thought, cannot be denied to true Being (παντελῶς ὄντι), and that the holy reason (ἄγιον νοῦν) can be nowhere, and in nothing that is unmoved.[36] Plato thus has a clear consciousness of having got further than Parmenides when he says:— “Keep your mind from this way of inquiry, For never will you show that non-being is.”
Plato says that Being in anyone partakes both of Being and non-being; but what thus participates is different both from Being and non-being as such.[37] This dialectic combats two things in particular; and in the first place it is antagonistic to the common dialectic in the ordinary sense, of which we have already spoken. Examples of this false dialectic to which Plato often comes back, are specially frequent amongst the Sophists; yet he did not show sufficiently clearly how they are distinguished from the purely dialectical knowledge which is in the Notion. For example, Plato expressed his dissent when Protagoras and others said that no determination is absolutely certain—that bitter is not objective, for what to one person is bitter, to another is sweet. Similarly, large and small, more and less, &c., are relative, because the large will be, in other circumstances, small, and the small will be great. That is to say, the unity of opposites is present to us in everything we know, but the common way of looking at things, in which the rational does not come to consciousness, always holds the opposites asunder, as though they were simply opposed in a determinate way. As in each thing we demonstrate unity, so do we also show its multiplicity, for it has many parts and qualities. In the Parmenides, Plato, as we saw above (p. 58), objected to this unity of opposites, because it must thereby be said that something is one in quite another respect from that in which it is many. We thus do not here bring these thoughts together, for the conception and the words merely go backwards and forwards from the one to the other; if this passing to and fro is performed with consciousness, it is the empty dialectic which does not really unite the opposites. Of this Plato says, “If anyone thinks he has made a wonderful discovery in ascertaining that he can drag thoughts this way and that, from one determination to another, he may be told that he has done nothing worthy of praise; for in so doing there is nothing excellent or difficult.” The dialectic that annuls a determination because it reveals in it some defect, and then goes on to establish another, is thus wrong. “The point of difficulty, and what we ought to aim at, is to show that what is the other is the same, and what is the same, is another, and likewise in the same regard and from the same point of view to show that the one has in them come into existence if the other determination is revealed within them. But to show that somehow the same is another, and the other also the same, that the great is also small” (_e.g._ Protagoras’s die), “and the like also unlike, and to delight in thus always proving opposites, is no true inquiry (ἔλενχος), but simply proves that he who uses such arguments is a neophyte,” in thought, “who has just begun to investigate truth. To separate all existences from one another is the crude attempt of an uncultured and unphilosophical mind. To cause everything to fall asunder means the perfect annihilation of all thought, for thought is the union of ideas.”[38] Thus Plato expressly speaks against the dialectic of showing how anything may be refuted from some point of view or another. We see that Plato, in respect of content, expresses nothing excepting what is called indifference in difference, the difference of absolute opposites and their unity. To this speculative knowledge he opposes the ordinary way of thinking, which is positive as well as negative; the former, not bringing the thoughts together, allows first one and then the other to have value in their separation; the latter is, indeed, conscious of a unity, though it is of a superficial, differentiating unity in which the two moments are separate, as standing in different aspects.
The second point against which Plato argues is the dialectic of the Eleatics, and their assertion, which in its nature resembles that of the Sophists, that only Being is, and non-being is not. To the Sophists this means, as Plato puts it: Since the negative is not, but only Being is, there is nothing false; everything existent, everything which is for us, is thus necessarily true, and what is not, we do not know or feel. Plato reproaches the Sophists for thus doing away with the difference between true and false.[39] Having arrived at this stage in the knowledge of the dialectic (and the whole matter is merely a difference of stages) the Sophists could allow what they promise—that everything that the individual, according to his belief, makes his end and interest, is affirmative and right. Hence it cannot be said that such and such an act is wrong, wicked, a crime; for this would be to say that the maxim of the action is wrong. No more can it be said that such and such opinion is deceptive, for in the opinion of the Sophists the proposition implies that what I feel or represent to myself, in as far as it is mine, is an affirmative content, and thus true and right. The proposition in itself seems quite abstract and innocent, but we first notice what is involved in such abstractions when we see them in concrete form. According to this innocent proposition there would be no wickedness and no crime. The Platonic dialectic is essentially different from this kind of dialectic.
What is further present to the mind of Plato is that the Idea, the absolute universal, good, true, and beautiful, is to be taken for itself. The myth, which I have already quoted (p. 27 _et seq._), indeed goes to prove that we must not consider a good action, a noble man—not the subject of which these determinations are predicated. For that which appears in such conceptions or perceptions as predicate, must be taken for itself, and this is the absolute truth. This tallies with the nature of the dialectic which has been described. An action, taken in accordance with the empirical conception, may be called right; in another aspect, quite opposite determinations may be shown to be in it. But the good and true must be taken on their own account without such individualities, without this empirical and concrete character; and the good and true thus taken alone, constitute that which is. The soul which, according to the divine drama, is found in matter, rejoices in a beautiful and just object; but the only actual truth is in absolute virtue, justice, and beauty. It is thus the universal for itself which is further determined in the Platonic dialectic; of this several forms appear, but these forms are themselves still very general and abstract. Plato’s highest form is the identity of Being and non-being. The true is that which is, but this Being is not without negation. Plato’s object is thus to show that non-being is an essential determination in Being, and that the simple, self-identical, partakes of other-being. This unity of Being and non-being is also found in the Sophists; but this alone is not the end of the matter. For in further investigation Plato comes to the conclusion that non-being, further determined, is the essence of the ‘other’: “Ideas mingle, and Being and the other (θάτερον) go through everything and through one another; the other, because it participates (μετασχόν) in Being, certainly _is_ through this indwelling Being, but it is not identical with that of which it partakes, being something different, and being other than Being, it is clearly non-being. But since Being likewise partakes of other-being, it also is different from other Ideas, and is not any one of them; so that there are thousands of ways in which it is not, and as regards all else, whether looked at individually or collectively, it in many respects is, and in many respects is not.”[40] Plato thus maintains that the other, as the negative, non-identical, is likewise in one and the same respect the self-identical; there are not different sides which are in mutual opposition.
These are the principal points in Plato’s peculiar dialectic. The fact that the Idea of the divine, eternal, beautiful, is absolute existence, is the beginning of the elevation of consciousness into the spiritual, and into the consciousness that the universal is true. It may be enough for the ordinary idea to be animated and satisfied by the conception of the beautiful and good, but thinking knowledge demands the determination of this eternal and divine. And this determination is really only free determination which certainly does not prevent universality—a limitation (for every determination is limitation) which likewise leaves the universal in its infinitude free and independent. Freedom exists only in a return into itself; the undistinguished is the lifeless; the active, living, concrete universal is hence what inwardly distinguishes itself, but yet remains free in so doing. Now this determinateness consists in the one being identical with itself in the other, in the many, in what is distinguished. This constitutes the only truth, and the only interest for knowledge in what is called Platonic philosophy, and if this is not known, the main point of it is not known. While in the example already often quoted (pp. 58, 64),[41] in which Socrates is both one and many, the two thoughts are made to fall asunder, it is left to speculative thought alone to bring the thoughts together, and this union of what is different, of Being and non-being, of one and many, &c., which takes place without a mere transition from one to another, constitutes the inmost reality and true greatness of Platonic philosophy. This determination is the esoteric element in Platonic philosophy, and the other is the exoteric; the distinction is doubtless an unwarranted one, indicating, as it seems to do, that Plato could have two such philosophies—one for the world, for the people, and the other, the inward, reserved for the initiated. But the esoteric is the speculative, which, even though written and printed, is yet, without being any secret, hidden from those who have not sufficient interest in it to exert themselves. To this esoteric portion pertain the two dialogues hitherto considered, along with which the Philebus may in the third place be taken.
_c._ In the Philebus Plato investigates the nature of pleasure; and the opposition of the infinite and finite, or of the unlimited (ἄπειρον) and limiting (πέρας), is there more especially dealt with. In keeping this before us, it would scarcely occur to us that through the metaphysical knowledge of the nature of the infinite and undetermined, what concerns enjoyment is likewise determined; but these pure thoughts are the substantial through which everything, however concrete or seemingly remote, is decided. When Plato treats of pleasure and wisdom as contrasted, it is the opposition of finite and infinite. By pleasure we certainly represent to ourselves the immediately individual, the sensuous; but pleasure is the indeterminate in respect that it is the merely elementary, like fire and water, and not the self-determining. Only the Idea is the self-determinate, or self-identity. To our reflection the infinite appears to be what is best and highest, limitation being inferior to it; and ancient philosophers so determined it. By Plato, however, it is, on the other hand, shown that the limited is the true, as the self-determining, while the unlimited is still abstract; it certainly can be determined in many different ways, but when thus determined it is only the individual. The infinite is the formless; free form as activity is the finite, which finds in the infinite the material for self-realization. Plato thus characterizes enjoyment dependent on the senses as the unlimited which does not determine itself; reason alone is the active determination. But the infinite is what in itself passes over to the finite; thus the perfect good, according to Plato, is neither to be sought for in happiness or reason, but in a life of both combined. But wisdom, as limit, is the true cause from which what is excellent arises.[42] As that which posits measure and end, it is what absolutely determines the end—the immanent determination with which and in which freedom likewise brings itself into existence.
Plato further considers the fact that the true is the identity of opposites, thus. The infinite, as the indeterminate, is capable of a more or less, it may be more intensive or not; thus colder and warmer, drier and moister, quicker and slower, &c., are all such. What is limited is the equal, the double, and every other measure; by this means the opposite ceases to be unlike and becomes uniform and harmonious. Through the unity of these opposites, such as cold and warm, dry and moist, health arises; similarly the harmony of music takes its origin from the limitation of high tones and deep, of quicker and slower movement, and, generally speaking, everything beautiful and perfect arises through the union of opposites. Health, happiness, beauty, &c., would thus appear to be begotten, in as far as the opposites are allied thereto, but they are likewise an intermingling of the same. The ancients make copious use of intermingling, participation, &c., instead of individuality; but for us these are indefinite and inadequate expressions. But Plato says that the third, which is thus begotten, pre-supposes the cause or that from which it is formed; this is more excellent than those through whose instrumentality that third arose. Hence Plato has four determinations; first the unlimited, the undetermined; secondly the limited, measure, proportion, to which pertains wisdom; the third is what is mingled from both, what has only arisen; the fourth is cause. This is in itself nothing else than the unity of differences, subjectivity, power and supremacy over opposites, that which is able to sustain the opposites in itself; but it is only the spiritual which has this power and which sustains opposition, the highest contradiction in itself. Weak corporeality passes away as soon as ‘another’ comes into it. The cause he speaks of is divine reason, which governs the world; the beauty of the world which is present in air, fire, water, and in all that lives, is produced thereby.[43] Thus the absolute is what in one unity is finite and infinite.
When Plato speaks thus of the beautiful and good, these are concrete ideas, or rather there is only one idea. But we are still far from these concrete ideas when we begin with such abstractions as Being, non-being, unity, and multiplicity. If Plato, however, has not succeeded in bringing these abstract thoughts through further development and concretion, to beauty, truth, and morality, there at least lies in the knowledge of those abstract determinations, the criterion by which the concrete is determined, as also its sources. This transition to the concrete is made in the Philebus, since the principle of feeling and of pleasure is there considered. The ancient philosophers knew very well what they had of concrete in those abstract thoughts. In the atomic principle of multiplicity we thus find the source of a construction of the state, for the ultimate thought-determination of such state-principles is the logical. The ancients in their pure Philosophy had not the same end in view as we—they had not the end of a metaphysical sequence placed before them like a problem. We, on the other hand, have something concrete before us, and desire to reduce it to settled order. With Plato Philosophy offers the path which the individual must follow in order to attain to any knowledge, but, generally speaking, Plato places absolute and explicit happiness, the blessed life itself, in the contemplation during life of the divine objects named above.[44] This contemplative life seems aimless, for the reason that all its interests have disappeared. But to live in freedom in the kingdom of thought had become the absolute end to the ancients, and they knew that freedom existed only in thought.
2. PHILOSOPHY OF NATURE.
With Plato Philosophy likewise commenced to devote more attention to the understanding of what is further determined, and in this way the matter of knowledge began to fall into divisions. In the Timæus the Idea thus makes its appearance as expressed in its concrete determinateness, and the Platonic Philosophy of Nature hence teaches us to have a better knowledge of the reality of the world; we cannot, however, enter into details, and if we did, they have little interest. It is more especially where Plato treats of physiology that his statements in no way correspond with what we now know, although we cannot fail to wonder at the brilliant glimpses of the truth there found, which have been only too much misconceived by the moderns. Plato derived a great deal from the Pythagoreans; how much is theirs, however, cannot be satisfactorily determined. We remarked before (p. 14) that the Timæus is really the fuller version of a Pythagorean treatise; other would-be wise persons have indeed said that the treatise is only an abstract made by a Pythagorean of the larger work of Plato, but the first theory is the more probable. The Timæus has in all times been esteemed the most difficult and obscure of the Platonic dialogues. This difficulty is due in part to the apparent mingling of conceiving knowledge and ordinary perception already mentioned (p. 20), just as we shall presently find an intermingling of Pythagorean numbers; and it is due still more to the philosophic nature of the matter in hand, of which Plato was as yet unconscious. The second difficulty lies in the arrangement of the whole, for what at once strikes one is that Plato repeatedly breaks off the thread of his argument, often appearing to turn back and begin again from the beginning.[45] This moved critics such as August Wolff and others, who could not understand it philosophically, to take the Timæus to be an accumulation of fragments put together, or else to be several works which had only been loosely strung together into one, or into the Platonic portion of which much that is foreign had been introduced. Wolff accordingly thought it was evident from this that the dialogue, like Homer’s poems, had been, in its first form, spoken and not written. But although the connection seems unmethodical, and Plato himself makes what maybe called copious excuses for the confusion, we shall find how the whole matter really falls into natural divisions, and we shall also find the deep inward reason which makes necessary the frequent return to what apparently is the beginning.
An exposition of the reality of nature or of the becoming of the world is introduced by Plato in the following way: “God is the Good,” this stands also at the head of the Platonic Ideas in the verbally delivered discourses (_supra_, p. 11); “goodness, however, has no jealousy of anything, and being free from jealousy, God desired to make all things like Himself.”[46] God here is still without determination, and a name which has no meaning for thought; nevertheless, where Plato in the Timæus again begins from the beginning, he is found to have a more definite idea of God. That God is devoid of envy undoubtedly is a great, beautiful, true, and childlike thought. With the ancients, on the contrary, we find in Nemesis, Dike, Fate, Jealousy, the one determination of the gods: moved by this they cast down the great and bring it low, and suffer not what is excellent and elevated to exist. The later high-minded philosophers controverted this doctrine. For in the mere idea of the Nemesis no moral determination is as yet implied, because punishment there is only the humiliation of what oversteps limits, but these limits are not yet presented as moral, and punishment is thus not yet a recognition of the moral as distinguished from the immoral. Plato’s thought is thus much higher than that of most of our moderns, who, in saying that God is a hidden God who has not revealed Himself to us and of whom we can know nothing, ascribe jealousy to God. For why should He not reveal Himself to us if we earnestly seek the knowledge of Him? A light loses nothing by another’s being kindled therefrom, and hence there was in Athens a punishment imposed on those who did not permit this to be done. If the knowledge of God were kept from us in order that we should know only the finite and not attain to the infinite, God would be a jealous God, or God would then become an empty name. Such talk means no more than that we wish to neglect what is higher and divine, and seek after our own petty interests and opinions. This humility is sin—the sin against the Holy Ghost.
Plato continues: “God found the visible” (παραλαβών)—a mythical expression proceeding from the necessity of beginning with an immediate, which, however, as it presents itself, cannot in any way be allowed—“not at rest, but moving in an irregular and disorderly manner; and out of disorder he brought order, considering that this was far better than the other.” From this it appears as if Plato had considered that God was only the δημιοῦργος, _i.e._ the disposer of matter, and that this, being eternal and independent, was found by Him as chaos; but in view of what has been said, this is false. These are not the philosophic doctrines which Plato seriously held, for he speaks here only after the manner of the ordinary conception, and such expressions have hence no philosophic content. It is only the introduction of the subject, bringing us, as it does, to determinations such as matter. Plato then comes in course of his progress to further determinations, and in these we first have the Notion; we must hold to what is speculative in Plato, and not to the first-mentioned ordinary conception. Likewise, when he says that God esteemed order to be the best, the mode of expression is naïve. Nowadays we should ask that God should first be proved; and just as little should we allow the visible to be established without much further ado. What is proved by Plato from this more naïve method of expression is, in the first place, the true determination of the Idea, which only appears later on. It is further said: “God reflecting that of what is visible, the unintelligent (ἀνόητον) could not be fairer than the intelligent (νοῦς), and that intelligence could not exist in anything devoid of soul, for these reasons put intelligence in the soul, and the soul in the body, and so united them that the world became a living and intelligent system, an animal.” We have reality and intelligence, and the soul as the bond connecting the two extremes, without which intelligence could not have part in the visible body; we saw the true reality comprehended by Plato in a similar way in the Phædrus (_supra_, p. 39). “There is, however, only one such animal, for were there two or more, these would be only parts of the one, and only one.”[47] Plato now first proceeds to the determination of the Idea of corporeal existence: “Because the world was to become corporeal, visible and tangible, and since without fire nothing can be seen, and without solidity, without earth, nothing can be touched, God in the beginning made fire and earth.” In this childlike way Plato introduces these extremes, solidity and life. “But two things cannot be united without a third, there must be a bond between them, uniting both”—one of Plato’s simple methods of expression. “The fairest bond, however, is that which most completely fuses itself and that which is bound by it.” That is a profound saying, in which the Notion is contained; the bond is the subjective and individual, the power which dominates the other, which makes itself identical with it. “Proportion” (ἀναλογία) is best adapted to effect such a fusion; that is, whenever of three numbers or magnitudes or powers, that which is the mean is to the last term what the first term is to the mean, and again when the mean is to the first term as the last term is to the mean (a: b = b: c) “then the mean having become the first and last, and the first and last both having become means, all things will necessarily come to be the same; but having come to be the same, everything will be one.”[48] This is excellent, we have still preserved this in our Philosophy; it is the distinction which is no distinction. This diremption from which Plato proceeds, is the conclusion which we know from logic; it appears in the form of the ordinary syllogism, in which, however, the whole rationality of the Idea is, at least externally, contained. The distinctions are the extremes, and the mean is the identity which in a supreme degree makes them one; the conclusion is thus speculative, and in the extremes unites itself with itself, because all the terms pass through all the different positions. It is hence a mistake to disparage the conclusion and not to recognize it as the highest and absolute form; in respect of the conclusions arrived at by the understanding, on the contrary, we should be right in rejecting it. This last has no such mean; each of the differences is there recognized as different in its own independent form, as having a character different from that of the other. This, in the Platonic philosophy, is abrogated, and the speculative element in it constitutes the proper and true form of conclusion, in which the extremes neither remain in independence as regards themselves, nor as regards the mean. In the conclusion of the understanding, on the contrary, the unity which is constituted is only the unity of essentially different contents which remain such; for here a subject, a determination, is, through the mean, simply bound up with another, or “some conception is joined to some other conception.” In a rational conclusion, however, the main point of its speculative content is the identity of the extremes which are joined to one another; in this it is involved that the subject presented in the mean is a content which does not join itself with another, but only through the other and in the other with itself. In other words, this constitutes the essential nature of God, who, when made subject, is the fact that He begot His Son, the world; but in this reality which appears as another, He still remains identical with Himself, does away with the separation implied in the Fall, and, in the other, merely unites Himself to Himself and thus becomes Spirit. When the immediate is elevated over the mediate and it is then said that God’s actions are immediate, there is, indeed, good ground for the assertion; but the concrete fact is that God is a conclusion which, by differentiating itself, unites itself to itself, and, through the abrogation of the mediation, reinstates its own immediacy. In the Platonic philosophy we thus have what is best and highest; the thoughts are, indeed, merely pure thoughts, but they contain everything in themselves; for all concrete forms depend on thought-determinations alone. The Fathers thus found in Plato the Trinity which they wished to comprehend and prove in thought: with Plato the truth really has the same determination as the Trinity. But these forms have been neglected for two thousand years since Plato’s time, for they have not passed into the Christian religion as thoughts; indeed they were considered to be ideas which had entered in through error, until quite recent times, when men began to understand that the Notion is contained in these determinations, and that nature and spirit can thus be comprehended through their means.
Plato continues: “Since what is solid requires two means, because it not only has breadth but also depth, God has placed air and water between fire and earth; and indeed He gave to them the same proportion, so that fire is related to air as air to water, and as air is to water, so is water to earth.”[49] Thus we have, properly speaking, four methods of representing space, inasmuch as the point is, through line and surface, closely bound up with the solid body. The sundered mean here discovered, again indicates an important thought of logical profundity; and the number four which here appears, is in nature a fundamental number. For as being the different which is turned towards the two extremes, the mean must be separated in itself. In the conclusion in which God is the One, the second (the mediating), the Son; the third, the Spirit; the mean indeed is simple. But the cause why that which in the rational conclusion is merely three-fold, passes in nature to the four-fold, rests in what is natural, because what in thought is immediately the one, becomes separate in Nature. But in order that in Nature the opposition should exist as opposition, it must itself be a twofold, and thus, when we count, we have four. This also takes place in the conception of God, for when we apply it to the world, we have nature as mean and the existent spirit as the way of return for nature: when the return is made, this is the absolute Spirit. This living process, this separation and unifying of differences, is the living God.
Plato says further: “Through this unity the visible and tangible world has been made. And it comes to pass by God’s having given to it these elements entire and unseparated, that it is perfect, and unaffected by age and disease. For old age and disease only arise from a body’s being worked upon by a superabundance of such elements from without. But here this is not so, for the world contains those elements entirely in itself, and nothing can come to it from without. The world is spherical in form,” (as it was to Parmenides and the Pythagoreans) “as being most perfect, and as containing all others in itself; it is perfectly smooth, since for it there is nothing outside, and it requires no limbs.” Finitude consists in this, that a distinction as regards something else is an externality to some other object. In the Idea we certainly have determination, limitation, difference, other-being, but it is at the same time dissolved, contained, gathered together, in the one. Thus it is a difference through which no finitude arises, seeing that it likewise is sublated. Finitude is thus in the infinite itself, and this is, indeed, a great thought. “God gave the world the most appropriate motion of all the seven, being that which harmonizes best with mind and consciousness, motion in a circle; the other six He took away from it and liberated it from their variations”[50] (movements backwards and forwards). This is only a popular way of putting it.
