Let us live so we do not regret years of inertia and ignorance, so when we die we can say all of our energy was dedicated to the noble liberation of the human mind and spirit, beginning with my own.
There is only one thing about which I shall have no regrets when my life ends. I have savored to the full all the small, daily joys. The bright sunshine on the breakfast table; the smell of the air at dusk; the sound of the clock ticking; the light rains that start gently after midnight; the hour when the family come home; Sunday-evening tea before the fire! I have never missed one moment of beauty, not even taken it for granted. Spring, summer, autumn, or winter. I wish I had failed as little in other ways.
I know, that since life is our most precious gift, and as far as we can be absolutely certain, it's given to us to live but once, let us so live we will not regret years of useless virtue, and inertia, and timidity, and ignorance, and in our last moments we can say: 'All my life, all my conscious energies, have been dedicated to the most noble cause in the world, the liberation of the human mind and spirit - beginning with my own'.
Unconsciously we all have a standard by which we measure other men, and if we examine closely we find that this standard is a very simple one, and is this: we admire them, we envy them, for great qualities we ourselves lack. Hero worship consists in just that. Our heroes are men who do things which we recognize, with regret, and sometimes with a secret shame, that we cannot do. We find not much in ourselves to admire, we are always privately wanting to be like somebody else. If everybody was satisfied with himself, there would be no heroes.
There is a longing for a return to a time without the need for choices, free of the regret at the inevitable loss that all choice (however wonderful) has entailed.
It is a matter for considerable regret that Fermat, who cultivated the theory of numbers with so much success, did not leave us with the proofs of the theorems he discovered. In truth, Messrs Euler and Lagrange, who have not disdained this kind of research, have proved most of these theorems, and have even substituted extensive theories for the isolated propositions of Fermat. But there are several proofs which have resisted their efforts.
Yet you shall not deplore having known blindness, nor regret having been deaf. For in that day you shall know the hidden purposes in all things. And you shall bless darkness as you would bless light.
The only time you really live fully is from thirty to sixty. The young are slaves to dreams; the old servants of regrets. Only the middle-aged have all their five senses in the keeping of their wits.
