In the Penguin Books Great Ideas series, Seneca On the Shortness of Life translated by C.D.N. Costa.
You should rather suppose that those are involved in worthwhile duties who wish to have daily as their closest friends Zeno, Pythagoras, Democritus and all the other high priests of liberal studies, and Aristotle and Theophrastus.

They are at home to all mortals by night and by day.
The cover design supplies an additional message: Life is Long If You Know How to Use It.
And so for day 2437
