The proposition of Thales, that water is the Absolute, or as the ancients say, the principle, is the beginning of Philosophy, because with it the consciousness is arrived at that essence, truth, that which is alone in and for itself, are one. A departure from what is in our sensuous perception here takes place; man recedes from this immediate existence. We must be able to forget that we are accustomed to a rich concrete world of thought; with us the very child learns, “There is one God in Heaven, invisible.” Such determinations are not yet present here; the world of Thought must first be formed and there is as yet no pure unity. Man has nature before him as water, air, stars, the arch of the heavens; and the horizon of his ideas is limited to this. The imagination has, indeed, its gods, but its content still is natural; the Greeks had considered sun, mountains, earth, sea, rivers, &c., as independent powers, revered them as gods, and elevated them by the imagination to activity, movement, consciousness and will. What there is besides, like the conceptions of Homer, for instance, is something in which thought could not find satisfaction; it produces mere images of the imagination, endlessly endowed with animation and form, but destitute of simple unity. It must undoubtedly be said that in this unconsciousness of an intellectual world, one must acknowledge that there is a great robustness of mind evinced in not granting this plenitude of existence to the natural world, but in reducing it to a simple substance, which, as the ever enduring principle, neither originates nor disappears, while the gods have a Theogony and are manifold and changing. This wild, endlessly varied imagination of Homer is set at rest by the proposition that existence is water; this conflict of an endless quantity of principles, all these ideas that a particular object is an independent truth, a self-sufficient power over others existing in its own right, are taken away, and it is shown likewise that there is only one universal, the universal self-existent, the simple unimaginative perception, the thought that is one and one alone.
This universal stands in direct relationship to the particular and to the existence of the world as manifested. The first thing implied in what has been said, is that the particular existence has no independence, is not true in and for itself, but is only an accidental modification. But the affirmative point of view is that all other things proceed from the one, that the one remains thereby the substance from which all other things proceed, and it is only through a determination which is accidental and external that the particular existence has its being. It is similarly the case that all particular existence is transient, that is, it loses the form of particular and again becomes the universal, water. The simple proposition of Thales therefore, is Philosophy, because in it water, though sensuous, is not looked at in its particularity as opposed to other natural things, but as Thought in which everything is resolved and comprehended. Thus we approach the divorce of the absolute from the finite; but it is not to be thought that the unity stands above, and that down here we have the finite world. This idea is often found in the common conception of God—where permanence is attributed to the world and where men often represent two kinds of actuality to themselves, a sensuous and a supersensuous world of equal standing. The philosophic point of view is that the one is alone the truly actual, and here we must take actual in its higher significance, because we call everything actual in common life. The second circumstance to be remembered is that with the ancient philosophers, the principle has a definite and, at first, a physical form. To us this does not appear to be philosophic but only physical; in this case, however, matter has philosophic significance. Thales’ theory is thus a natural philosophy, because this universal essence is determined as real; consequently the Absolute is determined as the unity of thought and Being.
2. Now if we have this undifferentiated principle predominating, the question arises as to the determination of this first principle. The transition from universal to particular at once becomes essential, and it begins with the determination of activity; the necessity for such arises here. That which is to be a veritable principle must not have a one-sided, particular form, but in it the difference must itself be absolute, while other principles are only special kinds of forms. The fact that the Absolute is what determines itself is already more concrete; we have the activity and the higher self-consciousness of the spiritual principle, by which the form has worked itself into being absolute form, the totality of form. Since it is most profound, this comes latest; what has first to be done is merely to look at things as determined.
Form is lacking to water as conceived by Thales. How is this accorded to it? The method is stated (and stated by Aristotle, but not directly of Thales), in which particular forms have arisen out of water; it is said to be through a process of condensation and rarefaction (πυκνότητι καὶ μανότητι), or, as it may be better put, through greater or less intensity. Tennemann (vol. I. p. 59) in reference to this, cites from Aristotle, De gen. et corrupt. I. 1, where there is no mention of condensation and rarefaction as regards Thales, and further, De cælo, III. 5, where it is only said that those who uphold water or air, or something finer than water or coarser than air, define difference as density and rarity, but nothing is said of its being Thales who gave expression to this distinction. Tiedmann (vol. I. p. 38) quotes yet other authorities; it was, however, later on, that this distinction was first ascribed to Thales.[22] Thus much is made out, that for the first time in this natural philosophy as in the modern, that which is essential in form is really the quantitative difference in its existence. This merely quantitative difference, however, which, as the increasing and decreasing density of water, constitutes its only form-determination, is an external expression of the absolute difference; it is an unessential distinction set up through another and is not the inner difference of the Notion in itself; it is therefore not worth while to spend more time over it.
Difference as regards the Notion has no physical significance, but differences or the simple duality of form in the sides of its opposition, must be comprehended as universally in the Notion. On this account a sensuous interpretation must not be given to the material, that is to particular determinations, as when it is definitely said that rare water is air, rare air, fiery ether, thick water, mud, which then becomes earth; according to this, air would be the rarefaction of the first water, ether the rarefaction of air, and earth and mud the sediment of water. As sensuous difference or change, the division here appears as something manifested for consciousness; the moderns have experimented in making thicker and thinner what to the senses is the same.
Change has consequently a double sense; one with reference to existence and another with reference to the Notion. When change is considered by the ancients, it is usually supposed to have to do with a change in what exists, and thus, for instance, inquiry would be made as to whether water can be changed through chemical action, such as heat, distillation, &c., into earth; finite chemistry is confined to this. But what is meant in all ancient philosophies is change as regards the Notion. That is to say, water does not become converted into air or space and time in retorts, &c. But in every philosophic idea, this transition of one quality into another takes place, i.e. this inward connection is shown in the Notion, according to which no one thing can subsist independently and without the other, for the life of nature has its subsistence in the fact that one thing is necessarily related to the other. We certainly are accustomed to believe that if water were taken away, it would indeed fare badly with plants and animals, but that stones would still remain; or that of colours, blue could be abstracted without harming in the least yellow or red. As regards merely empirical existence, it may easily be shown that each quality exists on its own account, but in the Notion they only are, through one another, and by virtue of an inward necessity. We certainly see this also in living matter, where things happen in another way, for here the Notion comes into existence; thus if, for example, we abstract the heart, the lungs and all else collapse. And in the same way all nature exists only in the unity of all its parts, just as the brain can exist only in unity with the other organs.
3. If the form is, however, only expressed in both its sides as condensation and rarefaction, it is not in and for itself, for to be this it must be grasped as the absolute Notion, and as an endlessly forming unity. What is said on this point by Aristotle (De Anima, I. 2, also 5) is this: “Thales seems, according to what is said of him, to consider the soul as something having movement, for he says of the loadstone that it has a soul, since it moves the iron.” Diogenes Laertius (I. 24) adds amber to this, from which we see that even Thales knew about electricity, although another explanation of it is that ἤλεκτρον was besides a metal. Aldobrandini says of this passage in Diogenes, that it is a stone which is so hostile to poison that when touched by such it immediately hisses. The above remark by Aristotle is perverted by Diogenes to such an extent that he says: “Thales has likewise ascribed a soul to what is lifeless.” However, this is not the question, for the point is how he thought of absolute form, and whether he expressed the Idea generally as soul so that absolute essence should be the unity of simple essence and form.
Diogenes certainly says further of Thales (I. 27), “The world is animated and full of demons,” and Plutarch (De plac. phil. I. 7) says, “He called God the Intelligence (νοῦς) of the world.” But all the ancients, and particularly Aristotle, ascribe this expression unanimously to Anaxagoras as the one who first said that the νοῦς is the principle of things. Thus it does not conduce to the further determination of form according to Thales, to find in Cicero (De Nat. Deor. I. 10) this passage: “Thales says that water is the beginning of everything, but God is the Mind which forms all that is, out of water.” Thales may certainly have spoken of God, but Cicero has added the statement that he comprehended him as the νοῦς which formed everything out of water. Tiedmann (vol. I. p. 42) declares the passage to be possibly corrupt, since Cicero later on (c. 11) says of Anaxagoras that “he first maintained the order of things to have been brought about through the infinite power of Mind.” However, the Epicurean, in whose mouth these words are put, speaks “with confidence only fearing that he should appear to have any doubts” (c. 8) both previously and subsequently of other philosophers rather foolishly, so that this description is given merely as a jest. Aristotle understands historic accuracy better, and therefore we must follow him. But to those who make it their business to find everywhere the conception of the creation of the world by God, that passage in Cicero is a great source of delight, and it is a much disputed point whether Thales is to be counted amongst those who accepted the existence of a God. The Theism of Thales is maintained by Plouquet, whilst others would have him to be an atheist or polytheist, because he says that everything is full of demons. However, this question as to whether Thales believed in God does not concern us here, for acceptation, faith, popular religion are not in question; we only have to do with the philosophic determination of absolute existence. And if Thales did speak of God as constituting everything out of this same water, that would not give us any further information about this existence; we should have spoken unphilosophically of Thales because we should have used an empty word without inquiring about its speculative significance. Similarly the word world-soul is useless, because its being is not thereby expressed.
Thus all these further, as also later, assertions do not justify us in maintaining that Thales comprehended form in the absolute in a definite manner; on the contrary, the rest of the history of philosophical development refutes this view. We see that form certainly seems to be shown forth in existence, but as yet this unity is no further developed. The idea that the magnet has a soul is indeed always better than saying that it has the power of attraction; for power is a quality which is considered as a predicate separable from matter, while soul is movement in unison with matter in its essence. An idea such as this of Thales stands isolated, however, and has no further relation to his absolute thought. Thus, in fact, the philosophy of Thales is comprised in the following simple elements: (a) It has constituted an abstraction in order to comprehend nature in a simple sensuous essence. (b) It has brought forth the Notion of ground or principle; that is, it has defined water to be the infinite Notion, the simple essence of thought, without determining it further as the difference of quantity. That is the limited significance of this principle of Thales.
