But that Xenophanes shows it to be neither limited nor infinite is clear from the very words quoted,—Alexander says that he regarded it as limited and spherical because it is homogeneous throughout; and he holds that it perceives all things, saying (Frag. 3) ‘But without effort he sets in motion all things by mind and thought.’[52] Theophrast. Fr. 5 a; Galen, in Hipp. _d. n. h._ xv. 35 K.; _Dox._ 481. Several of the commentators have made false statements about Xenophanes, as for instance Sabinos, who uses almost these very words: ‘I say that man is not air, as Anaximenes taught, nor water, as Thales taught, nor earth, as Xenophanes says in some book;’ but no such opinion is found to be expressed by Xenophanes anywhere. And it is clear from Sabinos’s own words that he made a false statement intentionally and did not fall into error through ignorance. Else he would certainly have mentioned by name the book in which Xenophanes expressed this opinion. On the contrary he wrote ‘as Xenophanes says in some book.’ Theophrastos would have recorded this opinion of Xenophanes in his abridgment of the opinions of the physicists, if it were really true. And if you are interested in the investigation of these things, you can read the books of Theophrastos in which he made this abridgment of the opinions of the physicists. Hipp. _Philos._ i. 14; _Dox._ 565. Xenophanes of Kolophon, son of Orthomenes, lived to the time of Cyrus. He was the first to say that all things are incomprehensible, in the following verses: (Frag. 14) ‘For even if one chances for the most part to say what is true, still he would not know; but every one thinks he knows.’[53] And he says that nothing comes into being, nor is anything destroyed, nor moved; and that the universe is one and is not subject to change. And he says that god is eternal and one, homogeneous throughout, limited, spherical, with power of sense-perception in all parts. The sun is formed each day from small fiery particles which are gathered together; the earth is infinite, and is not surrounded by air or by sky; an infinite number of suns and moons exist, and all things come from earth. The sea, he said, is salt because so many things flow together and become mixed in it; but Metrodoros assigns as the reason for its saltness that it has filtered through the earth.[54] And Xenophanes believes that once the earth was mingled with the sea, but in the course of time it became freed from moisture; and his proofs are such as these: that shells are found in the midst of the land and among the mountains, that in the quarries of Syracuse the imprints of a fish and of seals had been found, and in Paros the imprint of an anchovy at some depth in the stone, and in Melite shallow impressions of all sorts of sea products. He says that these imprints were made when everything long ago was covered with mud, and then the imprint dried in the mud. Farther he says that all men will be destroyed when the earth
