Seneca · On philosophy and riches
Letters 17.4
It is easy to fill a few stomachs, when they are well trained and crave nothing else but to be filled. Hunger costs but little; squeamishness costs much. Poverty is contented with fulfilling pressing needs.
Why, then, should you reject Philosophy as a comrade?
Seneca, Letters to Lucilius 17.4, translated by Richard Mott Gummere
