Further, a second point with Epicurus is the contemplation of death, the negative of existence, of self-consciousness in man; he requires us to have a true conception of death, because otherwise it disturbs our tranquillity. He accordingly says: “Accustom thyself then to the thought that death concerns us not; for all good and evil is a matter of sensation, but death is a deprivation (στέρησις) of sensation. Therefore the true reflection that death is no concern of ours, makes our mortal life one of enjoyment, since this thought does not add an endless length of days, but does away with the longing after immortality. For nothing in life has terrors for him who has once truly recognized the fact that not to live is not a matter of dread. Thus it is a vain thing to fear death, not because its presence but because the anticipation of it brings us pain. For how can the anticipation of a thing pain us when its reality does not? There is therefore in death nothing to trouble us. For when we are in life, death is not there, and when death is there, we are not. Therefore death does not concern either the living or the dead.” This is quite correct, if we look at the immediate; it is a thought full of meaning, and drives away fear. Mere privation, which death is, is not to be confounded with the feeling of being alive, which is positive; and there is no reason for worrying oneself about it. “But the future in general is neither ours, nor is it not ours; hence we must not count upon it as something that will come to pass, nor yet despair of it, as if it would not come to pass.”[166] It is no concern of ours either that it is or that it is not; and it need not therefore cause us uneasiness. This the right way in which to regard the future also.
