Seneca · On philosophers and kings
Letters 73.10
Our philosopher will therefore acknowledge that he owes a large debt to the ruler who makes it possible, by his management and foresight, for him to enjoy rich leisure, control of his own time, and a tranquillity uninterrupted by public employments.
Shepherd! a god this leisure gave to me, For he shall be my god eternally.
Seneca, Letters to Lucilius 73.10, translated by Richard Mott Gummere
