(γ) As to the real moments in which this ideal realizes itself, Aristotle further says, “He does not speak of them as four”—equivalents in juxtaposition—“but on the contrary as two; fire he puts by itself on the one side, and the three others, earth, air, and water, on the other.” What would be most interesting is the determination of their relationship.
(δ) In what deals with the relationship of the two ideal moments, friendship and strife, and of the four real elements, there is thus nothing rational, for Empedocles, according to Aristotle (Met. XII. 10), did not properly separate, but co-ordinated them, so that we often see them in proximity and counted as having equal value; but it is self-evident that Empedocles also separated these two sides, the real and the ideal, and expressed thought as their relation.
(ε) Aristotle says with justice (De gen. et corr. I. 1) that “Empedocles contradicts both himself and appearances. For at one time he maintains that none of the elements springs out of the other, but all else comes from them; and, at another time, he makes them into a whole through friendship, and again destroys this unity through strife. Thus through particular differences and qualities, one becomes water, the other fire, &c. Now if the particular differences are taken away (and they can be taken away since they have arisen), it is evident that water arises from earth, and the reverse. The All was not yet fire, earth, water, and air, when these were still one, so that it is not clear whether he made the one or the many to be, properly speaking, real existence.” Because the elements become one, their special character, that through which water is water, is nothing in itself, that is, they are passing into something different; but this contradicts the statement that they are the absolute elements, or that they are implicit. He considers actual things as an intermingling of elements, but in regard to their first origin, he thinks that everything springs from one through friendship and strife. This customary absence of thought is in the nature of synthetic conceptions; it now upholds unity, then multiplicity, and does not bring both thoughts together; as sublated, one is also not one.[78]
[F. Anaxagoras.]
With Anaxagoras[79] a light, if still a weak one, begins to dawn, because the understanding is now recognized as the principle. Aristotle says of Anaxagoras (Met. I. 3): “But he who said that reason (νοῦς), in what lives as also in nature, is the origin of the world and of all order, is like a sober man as compared with those who came before and spoke at random (εἰκῆ).” As Aristotle says, hitherto philosophers may “be compared to the fencers who fence in an unscientific way. Just as the latter often make good thrusts in their struggle, though not by any skill, these philosophers seem to speak without any knowledge of what they say.” Now if Anaxagoras, as a sober man amongst drunkards, was the first to reach this consciousness—for he says that pure thought is the actually existent universal and true—he yet, to a considerable extent, still thrusts into space.
The connection of his philosophy with what precedes is as follows: In Heraclitus’ Idea as motion, all moments are absolutely vanishing. Empedocles represents the gathering together of this motion into a unity, but into a synthetic unity; and with Leucippus and Democritus it is the same. With Empedocles, however, the moments of this unity are the existent elements of fire, water, &c., and with the others, pure abstractions, implicit being, thoughts. But in this way universality is directly asserted, for the opposing elements have no longer any sensuous support. We have had Being, Becoming, the One, as principles; they are universal thoughts and not sensuous, nor are they figures of the imagination; the content and its parts are, however, taken from what is sensuous, and they are thoughts in some sort of a determination. Anaxagoras now says that it is not gods, sensuous principles, elements, or thoughts—which really are determinations of reflection—but that it is the Universal, Thought itself, in and for itself, without opposition, all embracing, which is the substance or the principle. The unity as universal, returns from the opposition into itself, while in the synthesis of Empedocles, what is opposed is still apart from it and independent, and Thought is not Being. Here, however, Thought as pure, free process in itself, is the self-determining universal, and is not distinguished from conscious thought. In Anaxagoras quite new ground is thus opened up.
Anaxagoras concludes this period, and after him a fresh one begins. In accordance with the favourite idea of there being a genealogical descent of principles from the teacher to the taught, because he was an Ionian, he is often represented as perpetuating the Ionic school, and as an Ionic philosopher: Hermotimus of Clazomenæ, too, was his teacher. To support this theory Diogenes Laertius (II. 6) makes him a disciple of Anaximenes, whose birth is, however, placed in Ol. 55-58, or about sixty years earlier than that of Anaxagoras.
Aristotle says (Met. I. 3) that Anaxagoras first began by these determinations to express absolute reality as understanding. Aristotle and others after him, such as Sextus (adv. Math. IX. 7), mention the bare fact that Hermotimus gave rise to this conception, but it was clearly due to Anaxagoras. Little is gained if such a fact were true, since we learn no more about the philosophy of Hermotimus; it cannot have been much. Others have made numerous historical researches respecting this Hermotimus. The name we have already mentioned amongst those of whom it is said that Pythagoras existed in them before he lived as Pythagoras. We also have a story of Hermotimus to the effect that he possessed the peculiar gift of being able to make his soul quit his body. But this did him bad service in the end, since his wife, with whom he had a dispute, and who besides knew very well how matters stood, showed to their acquaintances this soul-deserted body as dead, and it was burnt before the soul reinstated itself—which soul must have been astonished.[80] It is not worth while to investigate what lies at the ground of these ancient stories, i.e. into how we should regard the matter: we may think of it as implying a state of ecstasy.
We must consider the life of Anaxagoras before his philosophy. Anaxagoras, according to Diogenes (II. 7), born in Ol. 70 (500 B.C.), comes earlier than Democritus, and in age also precedes Empedocles, yet, on the whole, he was contemporaneous with these, as also with Parmenides; he was as old as Zeno, and lived somewhat earlier than Socrates, but still they were acquainted with one another. His native town was Clazomenæ, in Lydia, not very far from Colophon and Ephesus, and situated on an isthmus by which a great peninsula is connected with the mainland. His life is shortly summed up in the statement that he devoted himself to the study of the sciences, withdrew from public affairs; according to Valerius Maximus (VIII. 7, extr. 6) he made numerous journeys, and finally, according to Tennemann (Vol. I. pp. 300, 415), in the forty-fifth year of his age, in the 81st Olympiad (456 B.C.), and at a propitious time, he came to Athens.
With him we thus find Philosophy in Greece proper, where so far there had been none, and coming, indeed, as far as Athens; hitherto either Asia Minor or Italy had been the seat of Philosophy, though, when the inhabitants of Asia Minor fell under Persian rule, with their loss of freedom, it expired amongst them. Anaxagoras, himself a native of Asia Minor, lived in the important period between the war of the Medes and the age of Pericles, principally in Athens, which had now reached the zenith of its greatness, for it was both the head of Grecian power, and the seat and centre of the arts and sciences. Athens, after the Persian wars, brought the greater part of the Greek islands into subjection, as also a number of maritime towns in Thrace, and even further into the Black Sea. As the greatest artists collected in Athens, so also did the most noted philosophers and sophists live there—a circle of luminaries in the arts and sciences such as we have in Æschylus, Sophocles, Aristophanes, Thucydides, Diogenes of Apollonia, Protagoras, Anaxagoras, and others from Asia Minor. Pericles then ruled the State, and raised it to that height of splendour which may be called the golden age in Athenian life; Anaxagoras, although living in the most flourishing time of Athenian life, touches on its decay, or rather reaches the first threatening of that decay, which ended in a total extermination of this beautiful life.
