Letters 44.3

Socrates was no aristocrat. Cleanthes worked at a well and served as a hired man watering a garden. Philosophy did not find Plato already a nobleman; it made him one. Why then should you despair of becoming able to rank with men like these? They are all your ancestors, if you conduct yourself in a manner worthy of them; and you will do so if you convince yourself at the outset that no man outdoes you in real nobility.
