LIFE OF DIOGENES, OF APOLLONIA.
I. Diogenes was a native of Apollonia, and the son of Apollothemis, a natural philosopher of high reputation; and he was, as Antisthenes reports, a pupil of Anaximenes. He was also a contemporary of Anaxagoras, and Demetrius Phalereus says, in his Defence of Socrates, that he was very unpopular at Athens, and even in some danger of his life.
II. The following were his principal doctrines; that the air was an element; that the worlds were infinite, and that the vacuum also was infinite; that the air, as it was condensed, and as it was rarified, was the productive cause of the worlds; that nothing can be produced out of nothing;[130] and that nothing can be destroyed so as to become nothing; that the earth is round, firmly planted in the middle of the universe, having acquired its situation from the circumvolutions of the hot principle around it, and its consistency from the cold.
The first words of his treatise are:—
“It appears to me that he who begins any treatise ought to lay down principles about which there can be no dispute, and that his exposition of them ought to be simple and dignified.”
LIFE OF ANAXARCHUS.
I. Anaxarchus was a native of Abdera. He was a pupil of Diogenes, of Smyrna; but, as some say, of Metrodorus, of Chios; who said that he was not even sure that he knew nothing; and Metrodorus was a pupil of Nessus, of Chios; though others assert that he was a disciple of Democritus.
II. Anaxarchus too enjoyed the intimacy of Alexander, and flourished about the hundred and tenth olympiad. He had for an enemy Nicocreon, the tyrant of Cyprus. And on one occasion, when Alexander, at a banquet, asked him what he thought of the entertainment, he is said to have replied, “O king, everything is provided very sumptuously; and the only thing wanting is to have the head of some satrap served up;” hinting at Nicocreon. And Nicocreon did not forget his grudge against him for this; but after the death of the king, when Anaxarchus, who was making a voyage, was driven against his will into Cyprus, he took him and put him in a mortar, and commanded him to be pounded to death with iron pestles. And then they say that he, disregarding this punishment, uttered that celebrated saying, “Beat the bag of Anaxarchus, but you will not beat Anaxarchus himself.” And then, when Nicocreon commanded that his tongue should be cut out, it is said that he bit it off, and spit it at him. And we have written an epigram upon him in the following terms:—
Beat more and more; you’re beating but a bag;
