Seneca · On the trials of travel
Letters 57.7
Do you suppose that I am now referring to the Stoics, who hold that the soul of a man crushed by a great weight cannot abide, and is scattered forthwith, because it has not had a free opportunity to depart? That is not what I am doing; those who think thus are, in my opinion, wrong.
Seneca, Letters to Lucilius 57.7, translated by Richard Mott Gummere
