Seneca · On the natural fear of death

Letters 82.8

This strength of heart, however, will come from constant study, provided that you practise, not with the tongue but with the soul, and provided that you prepare yourself to meet death. To enable yourself to meet death, you may expect no encouragement or cheer from those who try to make you believe, by means of their hair-splitting logic, that death is no evil. For I take pleasure, excellent Lucilius, in poking fun at the absurdities of the Greeks, of which, to my continual surprise, I have not yet succeeded in ridding myself.
