We cannot escape death, but death, rightly understood is no evil.

Context

“There is therefore no ground for the fear that we may incur the anger of the gods, or that we may suffer in Hades after death. Though subject to the powers of nature, which can be studied scientifically, we yet have free will, and are, within limits, the masters of our fate. We cannot escape death, but death, rightly understood is no evil. If we live prudently, according to the maxims of Epicurus, we shall probably achieve a measure of freedom from pain. This is a moderate gospel, but to a man impressed with human misery it sufficed to inspire enthusiasm.” source
