On Longevity

May 4, 2025

And what difference does it make how soon you depart from a place which you must depart from sooner or later? We should strive, not to live long, but to live rightly; for to achieve long life you have need of Fate only, but for right living you need the soul.
A life is really long if it is a full life; but fulness is not attained until the soul has rendered to itself its proper Good, that is, until it has assumed control over itself. What benefit does this older man derive from the eighty years he has spent in idleness?
A person like him has not lived; he has merely tarried awhile in life. Nor has he died late in life; he has simply been a long time dying. He has lived eighty years, has he? That depends upon the date from which you reckon his death! Your other friend, however, departed in the bloom of his manhood. But he had fulfilled all the duties of a good citizen, a good friend, a good son; in no respect had he fallen short. His age may have been incomplete, but his life was complete. The other man has lived eighty years, has he?
Nay, he has existed eighty years, unless perchance you mean by “he has lived” what we mean when we say that a tree “lives.”

And yet I would not on that account decline for myself a few additional years; although, if my life’s space be shortened, I shall not say that I have lacked aught that is essential to a happy life. For I have not planned to live up to the very last day that my greedy hopes had promised me; nay, I have looked upon every day as if it were my last.
Age ranks among the external things. How long I am to exist is not mine to decide, but how long I shall go on existing in my present way is in my own control. This is the only thing you have the right to require of me,—that I shall cease to measure out an inglorious age as it were in darkness, and devote myself to living instead of being carried along past life.

~ Seneca, Letter 93
