I cannot allow of the way in which we settle for ourselves the duration of our life. I see that the sages contract it very much in comparison of the common opinion: "what," said the younger Cato to those who would stay his hand from killing himself, "am I now of an age to be reproached that I go out of the world too soon?" And yet he was but eight-and-forty years old. He thought that to be a mature and advanced age, considering how few arrive unto it. And such as, soothing their thoughts with I know not what course of nature, promise to themselves some years beyond it, could they be privileged from the infinite number of accidents to which we are by a natural subjection exposed, they might have some reason so to do. What am idle conceit is it to expect to die of a decay of strength, which is the effect of extremest age, and to propose to ourselves no shorter lease of life than that, considering it is a kind of death of all others the most rare and very seldom seen? We call that only a natural death; as if it were contrary to nature to see a man break his neck with a fall, be drowned in shipwreck, be snatched away with a pleurisy or the plague, and as if our ordinary condition did not expose us to these inconveniences. Let us no longer flatter ourselves with these fine words; we ought rather, peradventure, to call that natural which is general, common, and universal.
To die of old age is a death rare, extraordinary, and singular, and, therefore, so much less natural than the others; 'tis the last and extremest sort of dying: and the more remote, the less to be hoped for.
It is, indeed, the bourn beyond which we are not to pass, and which the law of nature has set as a limit, not to be exceeded; but it is, withal, a privilege she is rarely seen to give us to last till then. 'Tis a lease she only signs by particular favour, and it may be to one only in the space of two or three ages, and then with a pass to boot, to carry him through all the traverses and difficulties she has strewed in the way of this long career. And therefore my opinion is, that when once forty years we should consider it as an age to which very few arrive. For seeing that men do not usually proceed so far, it is a sign that we are pretty well advanced; and since we have exceeded the ordinary bounds, which is the just measure of life, we ought not to expect to go much further; having escaped so many precipices of death, whereinto we have seen so many other men fall, we should acknowledge that so extraordinary a fortune as that which has hitherto rescued us from those eminent perils, and kept us alive beyond the ordinary term of living, is not like to continue long.
'Tis a fault in our very laws to maintain this error: these say that a man is not capable of managing his own estate till he be five-and-twenty years old, whereas he will have much ado to manage his life so long.
