Letters 49.11

You are mistaken if you think that only on an ocean voyage there is a very slight space between life and death. No, the distance between is just as narrow everywhere. It is not everywhere that death shows himself so near at hand; yet everywhere he is as near at hand.

Rid me of these shadowy terrors; then you will more easily deliver to me the instruction for which I have prepared myself. At our birth nature made us teachable, and gave us reason, not perfect, but capable of being perfected.

Seneca, Letters to Lucilius 49.11, translated by Richard Mott Gummere
