Specimens of his apophthegms may be found in Diogenes Laertius and the florilegium of Stobaeus, while there are traces of his influence in Seneca.
Many anecdotes, amusing rather than instructive, are related of him, which have been handed down by Diogenes Laertius and other writers.
The stories of the Stoics, who sought to refute the views of Epicurus by an appeal to his alleged antecedents and habits, were no doubt in the main, as Diogenes Laertius says, the stories of maniacs.
Aristotle'S Life This account is practically repeated by Diogenes Laertius in his Life of Aristotle, on the authority of the Chronicles of Apollodorus, who lived in the 2nd century B.C. Starting then from this tradition, near enough to the time, we can confidently divide Aristotle's career into four periods: his youth under his parents till his eighteenth year; his philosophical education under Plato at Athens till his thirty-eighth year; his travels in the Greek world till his fiftieth year; and his philosophical teaching in the Lyceum till his departure to Chalcis and his death in his sixtythird year.
Besides Truth, and the book Of the Gods which caused his condemnation at Athens, Diogenes Laertius attributes to him treatises on political, ethical, educational and rhetorical subjects.
We learn much more about the Stoic system from the scanty fragments of the first founders, 4 or even from the epitomes of Diogenes Laertius and Stobaeus, than from these writers.
The tradition which assigns the first employment of the Greek word 4aAoa041a to Pythagoras has hardly any claim to be regarded as authentic; and the somewhat self-conscious modesty to which Diogenes Laertius attributes the choice of the designation is, in all probability, a piece of etymology crystallized into narrative.
A smaller compilation, chiefly from Diogenes Laertius and Suidas, with a similar title, is the work of an unknown author of the 11th or 12th century.
