The body is unable to sense anything without the soul, as is the soul without the body. Therefore, when the soul leaves the body, no awareness remains. There cannot, according to Epicurus, be any afterlife. Death is a complete stop. This he regards as reason not to worry at all about dying: "death is nothing to us, for good and evil imply sentience, and death is the privation of all sentience." Life can only be enjoyable if one ceases to yearn for immortality, and renounces the fear of an endless afterlife in one or other torment: "either because of the myths, or because we are in dread of the mere insensibility of death, as if it had to do with us." When dying is simply ceasing to perceive, to feel, to be, there is nothing in it to dread.
Death, therefore, the most awful of evils, is nothing to us, seeing that, when we are, death is not come, and, when death is come, we are not.
Therefore, learning to live well is not different from learning to die well - the only reasonable way to prepare for the latter is to make the former, in itself and for itself, the fullest.

Transhumanism is so stupid.
