With Thales we, properly speaking, first begin the history of Philosophy. The life of Thales occurred at the time when the Ionic towns were under the dominion of Crœsus. Through his overthrow (Ol. 58, 1; 548 B.C.), an appearance of freedom was produced, yet the most of these towns were conquered by the Persians, and Thales survived the catastrophe only a few years. He was born at Miletus; his family is, by Diogenes (I. 22, 37), stated to be the Phœnician one of Thelides, and the date of his birth, according to the best calculation, is placed in the first year of the 35th Olympiad (640 B.C.), but according to Meiners it was a couple of Olympiads later (38th Olympiad, 629 B.C.). Thales lived as a statesman partly with Crœsus and partly in Miletus. Herodotus quotes him several times, and tells (I. 75) that, according to the narratives of the Greeks, when Crœsus went to battle against Cyrus and had difficulty in passing over the river Halys, Thales, who accompanied the army, diverted the river by a trench, which he made in the form of a crescent behind the camp, so that it could then be forded. Diogenes (I. 25) says further of him as regards his relations to his country, that he restrained the men of Miletus from allying themselves with Crœsus when he went against Cyrus, and that hence, after the conquest of Crœsus, when the other Ionic States were subdued by the Persians, the inhabitants of Miletus alone remained undisturbed.
Diogenes records, moreover (I. 23), that he soon withdrew his attention from the affairs of the State and devoted himself entirely to science.
Voyages to Phœnicia are recorded of him, which, however, rest on vague tradition; but that he was in Egypt in his old age seems undoubted.[19] There he was said to have learned geometry, but this would appear not to have been much, judging from the anecdote, which Diogenes (I. 24, 27) retails from a certain Hieronymus. It was to the effect that Thales taught the Egyptians to measure the height of their pyramids by shadow—by taking the relation borne by the height of a man to his shadow. The terms of the proportion are: as the shadow of a man is to the height of a man, so is the shadow of a pyramid to its height. If this were something new to the Egyptians, they must have been very far back in the theory of geometry. Herodotus tells (I. 74), moreover, that Thales foretold an eclipse of the sun that happened exactly on the day of the battle between the Medians and Lydians, and that he ascribed the rising of the Nile to the contrary Etesian winds, which drove back the waters.[20] We have some further isolated instances of, and anecdotes about his astronomical knowledge and works.[21] “In gazing at and making observations on the stars, he fell into a ditch, and the people mocked him as one who had knowledge of heavenly objects and yet could not see what lay at his own feet.” The people laugh at such things, and boast that philosophers cannot tell them about such matters; but they do not understand that philosophers laugh at them, for they do not fall into a ditch just because they lie in one for all time, and because they cannot see what exists above them. He also showed, according to Diogenes (I. 26), that a wise man, if he wishes, can easily acquire riches. It is more important that he fixed that the year, as solar year, should have 365 days. The anecdote of the golden tripod to be given to the wisest man, is recorded by Diogenes (I. 27-33); and it carries with it considerable weight, because he combines all the different versions of the story. The tripod was given to Thales or to Bias; Thales gave it to some one else, and thus it went through a circle until it again came to Thales; the latter, or else Solon, decided that Apollo was wisest, and sent it to Didyma or to Delphi. Thales died, according to Diogenes (I. 38), aged seventy-eight or ninety, in the 58th Olympiad; according to Tennemann (vol. i. p. 414), it was in Olympiad 59, 2 (543 B.C.), when Pythagoras came to Crotona. Diogenes relates that he died at one of the games, overcome by heat and thirst.
We have no writings by Thales, and we do not know whether he was in the habit of writing. Diogenes Laertius (I. 23, 34, 35) speaks of two hundred verses on astronomy, and some maxims, such as “It is not the many words that have most meaning.”
As to his philosophy, he is universally recognized as the first natural philosopher, but all one knows of him is little, and yet we seem to know the most of what there is. For since we find that the further philosophic progress of which his speculative idea was capable, and the understanding of his propositions, which they alone could have, make their first appearance and form particular epochs with the philosophers succeeding him, who may be recognized thereby, this development ascribed to Thales never took place with him at all. Thus if it is the case that a number of his other reflections have been lost, they cannot have had any particular speculative value; and his philosophy does not show itself to be an imperfect system from want of information about it, but because the first philosophy cannot be a system.
We must listen to Aristotle as regards these ancient philosophers, for he speaks most sympathetically of them. In the passage of most importance (Metaph. I. 3), he says: “Since it is clear that we must acquire the science of first causes (_ἐξ ἀρχῆς αἰτίν_), seeing that we say that a person knows a thing when he becomes acquainted with its cause, there are, we must recollect, four causes—Being and Form first (for the ‘why’ is finally led back to the Notion, but yet the first ‘why’ is a cause and principle); matter and substratum, second; the cause whence comes the beginning of movement, third; and fourth the cause which is opposed to this, the aim in view and the good (for that is the end of every origination). Hence we would make mention of those who have undertaken the investigation of Being before us, and have speculated regarding the Truth, for they openly advance certain principles and first causes. If we take them under our consideration, it will be of this advantage, so far as our present investigation goes, that we shall either find other kinds of causes or be enabled to have so much the more confidence in those just named. Most of the earliest philosophers have placed the principles of everything in something in the form of matter (_ἐν ὕλης εἴδει_), for, that from which everything existent comes, and out of which it takes its origin as its first source, and into which it finally sinks, as substance (_οὐσία_), ever remains the same and only changes in its particular qualities (_πάθεσι_); and this is called the element (_στοιχεῖον_) and this the principle of all that exists” (the absolute prius). “On this account they maintain that nothing arises or passes away, because the same nature always remains. For instance, we say that, absolutely speaking, Socrates neither originates if he becomes beautiful or musical, nor does he pass away if he loses these qualities, because the subject (_τὸ ὑποκείμενον_), Socrates, remains the same. And so it is with all else. For there must be one nature, or more than one, from which all else arises, because it maintains its existence” (_σωζομένης ἐκείνης_), that means that in its change there is no reality or truth. “All do not coincide as to the number of this principle or as to its description (_εἶδος_); Thales, the founder of this philosophy,” (which recognizes something material as the principle and substance of all that is), “says that it is water. Hence he likewise asserts the earth to be founded on water.” Water is thus the _ὑποκείμενον_, the first ground, and, according to Seneca’s statement (Quæst. Nat. vi. 6), it seems to him to be not so much the inside of the earth, as what encloses it which is the universal existence; for “Thales considered that the whole earth has water as its support (_subjecto humore_), and that it swims thereon.”
We might first of all expect some explanation of the application of these principles, as, for example, how it is to be proved that water is the universal substance, and in what way particular forms are deduced from it. But as to this we must say that of Thales in particular, we know nothing more than his principle, which is that water is the god over all. No more do we know anything further of Anaximander, Anaximenes and Diogenes than their principles. Aristotle brings forward a conjecture as to how Thales derived everything directly out of water, “Perhaps (_ἴσως_) the conclusions of Thales have been brought about from the reflection that it was evident that all nourishment is moist, and warmth itself comes out of moisture and thereby life continues. But that from which anything generates is the principle of all things. This was one reason for holding this theory, and another reason is contained in the fact that all germs are moist in character, and water is the principle of what is moist.” It is necessary to remark that the circumstances introduced by Aristotle with a “perhaps” which are supposed to have brought about the conclusions of Thales, making water the absolute essence of everything, are not adduced as the grounds acknowledged by Thales. And furthermore, they can hardly be called grounds, for what Aristotle does is rather to establish, as we would say from actuality, that the latter corresponds to the universal idea of water. His successors, as for instance Pseudo-Plutarch (De plac. phil. I. 3), have taken Thales’ assertion as positive and not hypothetical; Tiedmann (_Geist der spec. Phil._ vol. I. p. 36) remarks with great reason that Plutarch omits the “perhaps.” For Plutarch says, “Thales suggests (_στοχάζεται_) that everything takes its origin from water and resolves itself into the same, because as the germs of all that live have moisture as the principle of life, all else might likewise (_εἰκός_) take its principle from moisture; for all plants draw their nourishment, and thus bear fruit, from water, and if they are without it, fade away; and even the fires of sun, and stars and world are fed through the evaporation of water.” Aristotle is contented with simply showing in regard to moisture that, at least, it is everywhere to be found. Since Plutarch gives more definite grounds for holding that water is the simple essence of things, we must see whether things, in so far as they are simple essence, are water, (_α_) The germ of the animal, of moist nature, is undoubtedly the animal as the simple actual, or as the essence of its actuality, or undeveloped actuality.
(_β_) If, with plants, water may be regarded as for their nourishment, nourishment is still only the being of a thing as formless substance that first becomes individualized by individuality, and thus succeeds in obtaining form. (_γ_) To make sun, moon and the whole world arise through evaporation, like the food of plants, certainly approximates to the idea of the ancients, who did not allow the sun and moon to have obtained independence as we do.
“There are also some,” continues Aristotle, “who hold that all the ancients who, at the first and long before the present generation, made theology their study, understood Nature thus. They made Oceanus and Tethys the producers of all origination (_τῆς γενέσεως_), and water, which by the poets is called Styx, the oath of the gods. For what is most ancient is most revered, and the oath is that most held in reverence.” This old tradition has within it speculative significance. If anything cannot be proved or is devoid of objective form, such as we have in respect of payment in a discharge, or in witnesses who have seen the transaction, the oath, the confirmation of myself as object, expresses the fact that my assurance is absolute truth. Now since, by way of confirmation, men swear by what is best, by what is absolutely certain, and the gods swore by the subterranean water, it follows that the essence of pure thought, the inmost being, the reality in which consciousness finds its truth, is water; I, so to speak, express this clear certainty of myself as object, as God.
1. The closer consideration of this principle in its bearings would have no interest. For since the whole philosophy of Thales lies in the fact that water is this principle, the only point of interest can be to ask how far that principle is important and speculative. Thales comprehends essence as devoid of form. While the sensuous certitude of each thing in its individuality is not questioned, this objective actuality is now to be raised into the Notion that reflects itself into itself and is itself to be set forth as Notion; in commencement this is seen in the world’s being manifested as water, or as a simple universal. Fluid is, in its Notion, life, and hence it is water itself, spiritually expressed; in the so-called grounds or reasons, on the contrary, water has the form of existent universal. We certainly grant this universal activity of water, and for that reason call it an element, a physical universal power; but while we find it thus to be the universal of activity, we also find it to be this actual, not everywhere, but in proximity to other elements—earth, air and fire. Water thus has not got a sensuous universality, but a speculative one merely; to be speculative universality, however, would necessitate its being Notion and having what is sensuous removed. Here we have the strife between sensuous universality and universality of the Notion. The real essence of nature has to be defined, that is, nature has to be expressed as the simple essence of thought. Now simple essence, the Notion of the universal, is that which is devoid of form, but this water as it is, comes into the determination of form, and is thus, in relation to others, a particular existence just like everything that is natural. Yet as regards the other elements, water is determined as formless and simple, while the earth is that which has points, air is the element of all change, and fire evidently changes into itself. Now if the need of unity impels us to recognize for separate things a universal, water, although it has the drawback of being a particular thing, can easily be utilized as the One, both on account of its neutrality, and because it is more material than air.
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.
2. _Anaximander._ 2. _Anaximander._ Anaximander was also of Miletus, and he was a friend of Thales. “The latter,” says Cicero (Acad. Quaest. IV. 37), “could not convince him that everything consisted of water.” Anaximander’s father was called Praxiades; the date of his birth is not quite certain; according to Tennemann (vol. I. p. 413), it is put in Olympiad 42, 3 (610 B.C.), while Diogenes Laertius (II. I, 2) says, taking his information from Apollodorus, an Athenian, that in Ol. 58, 2 (547 B.C.), he was sixty-four years old, and that he died soon after, that is to say about the date of Thales’ death. And taking for granted that he died in his ninetieth year, Thales must have been nearly twenty-eight years older than Anaximander. It is related of Anaximander that he lived in Samos with the tyrant Polycrates, where were Pythagoras and Anacreon also. Themistius, according to Brucker (Pt. I. p. 478), says of him that he first put his philosophic thoughts into writing, but this is also recorded of others, as for example, of Pherecydes, who was older than he. Anaximander is said to have written about nature, the fixed stars, the sphere, besides other matters; he further produced something like a map, showing the boundary (_πρίμετρον_) of land and sea; he also made other mathematical inventions, such as a sun-dial that he put up in Lacedæmon, and instruments by which the course of the sun was shown, and the equinox determined; a chart of the heavens was likewise made by him.
His philosophical reflections are not comprehensive, and do not extend as far as to determination. Diogenes says in the passage quoted before: “He adduced the Infinite” (_τὸ ἄπειρον_, the undetermined), “as principle and element; he neither determined it as air or water or any such thing.” There are, however, few attributes of this Infinite given. (_α_.) “It is the principle of all becoming and passing away; at long intervals infinite worlds or gods rise out of it, and again they pass away into the same.” This has quite an oriental tone. “He gives as a reason that the principle is to be determined as the Infinite, the fact that it does not need material for continuous origination. It contains everything in itself and rules over all: it is divine, immortal, and never passes away.”[23] (_β_.) Out of the one, Anaximander separates the opposites which are contained in it, as do Empedocles and Anaxagoras; thus everything in this medley is certainly there, but undetermined.[24] That is, everything is really contained therein in possibility (_δυνάμει_), “so that,” says Aristotle (Metaphys. XI. 2), “it is not only that everything arises accidentally out of what is not, but everything also arises from what is, although it is from incipient being which is not yet in actuality.” Diogenes Laertius adds (II. 1): “The parts of the Infinite change, but it itself is unchangeable.” (_γ_.) Lastly, it is said that the infinitude is in size and not in number, and Anaximander differs thus from Anaxagoras, Empedocles and the other atomists, who maintain the absolute discretion of the infinite, while Anaximander upholds its absolute continuity.[25] Aristotle (Metaphys. I. 8) speaks also of a principle which is neither water nor air, but is “thicker than air and thinner than water.” Many have connected this idea with Anaximander, and it is possible that it belongs to him.
