Vitae philosophorum

Hermippus in his work On the Sages reckons seventeen, from which number different people make different selections of seven. They are: Solon, Thales, Pittacus, Bias, Chilon, Myson, Cleobulus, Periander, Anacharsis,

Here follow the extant letters of Thales.

Thales to Pherecydes

I hear that you intend to be the first Ionian to expound theology to the Greeks. And perhaps it was a wise decision to make the book common property without taking advice, instead of entrusting it to any particular persons whatsoever, a course which has no advantages. However, if it would give you any pleasure, I am quite willing to discuss the subject of your book with you; and if you bid me come to Syros I will do so. For surely Solon of Athens and I would scarcely be sane if, after having sailed to Crete to pursue our inquiries there, and to Egypt to confer with the priests and astronomers, we hesitated to come to you. For Solon too will come, with your permission.

You, however, are so fond of home that you seldom visit Ionia and have no longing to see strangers, but, as I hope, apply yourself to one thing, namely writing, while we, who never write anything, travel all over Hellas and Asia.

Thales to Solon

If you leave Athens, it seems to me that you could most conveniently set up your abode at Miletus, which is an Athenian colony; for there you incur no risk. If you are vexed at the thought that we are governed by a tyrant, hating as you do all absolute rulers, you would at least enjoy the society of your friends. Bias wrote inviting you to Priene; and if you prefer the town of Priene for a residence, I myself will come and live with you.
