“Once more what evil lust of life is this which constrains us with such force to be so mightily troubled in doubts and dangers? A sure term of life is fixed for mortals, and death cannot be shunned, but meet it we must. Moreover we are ever engaged, ever involved in the same pursuits, and no new pleasure is struck out by living on; but whilst what we crave is wanting, it seems to transcend all the rest; then when it has been gotten, we crave something else, and ever does the same thirst of life possess us, as we gape for it open-mouthed.” (de rerum natura)
