He has said further (and in this, according to Theophrastus, he agrees with Anaxagoras), “In the infinite the like separates itself from the unlike and allies itself to the like; thus what in the whole was gold becomes gold, what was earth, earth, &c., so that properly nothing originates, seeing that it was already there.”[27] These, however, are poor determinations, which only show the necessity of the transition from the undetermined to the determined; for this still takes place here in an unsatisfying way. As to the further question of how the infinite determines the opposite in its separation, it seems that the theory of the quantitative distinction of condensation and rarefaction was held by Anaximander as well as by Thales. Those who come later designate the process of separation from the Infinite as development. Anaximander supposes man to develop from a fish, which abandoned water for the land.[28] Development comes also into prominence in recent times, but as a mere succession in time—a formula in the use of which men often imagine that they are saying something brilliant; but there is no real necessity, no thought, and above all, no Notion contained in it. But in later records the idea of warmth, as being the disintegration of form, and that of cold, is ascribed to Anaximander by Stobæus (Eclog. Phys. c. 24, p. 500); this Aristotle (Metaphys. I. 5) first ascribed to Parmenides. Eusebius (De præp. Evang. I. 8), out of a lost work of Plutarch, gives us something from Anaximander’s Cosmogony which is dark, and which, indeed, Eusebius himself did not rightly understand. Its sense is approximately this: “Out of the Infinite, infinite heavenly spheres and infinite worlds have been set apart; but they carry within them their own destruction, because they only are through constant dividing off.” That is, since the Infinite is the principle, separation is the positing of a difference, i.e. of a determination or something finite. “The earth has the form of a cylinder, the height of which is the third part of the breadth. Both of the eternally productive principles of warmth and cold separate themselves in the creation of this earth, and a fiery sphere is formed round the air encircling the earth, like the bark around a tree. As this broke up, and the pieces were compressed into circles, sun, moon, and stars were formed.” Hence Anaximander, according to Stobæus (Ecl. Phys. 25, p. 510), likewise called the stars “wheel-shaped with fire-filled wrappings of air.” This Cosmogony is as good as the geological hypothesis of the earth-crust which burst open, or as Buffon’s explosion of the sun, which beginning, on the other hand, with the sun, makes the planets to be stones projected from it. While the ancients confined the stars to our atmosphere, and made the sun first proceed from the earth, we make the sun to be the substance and birthplace of the earth, and separate the stars entirely from any further connection
