Letters 6.7

Meanwhile, I owe you my little daily contribution; you shall be told what pleased me to-day in the writings of Hecato; it is these words: “What progress, you ask, have I made? I have begun to be a friend to myself.” That was indeed a great benefit; such a person can never be alone. You may be sure that such a man is a friend to all mankind. Farewell.

Seneca, Letters to Lucilius 6.7, translated by Richard Mott Gummere
