After all, I quite naturally want to live in order to fulfill my whole capacity for living, and not in order to fulfill my reasoning capacity alone, which is no more than some one-twentieth of my capacity for living. What does reason know? It knows only what it has managed to learn (and it may never learn anything else; that isn't very reassuring, but why not admit it?), while human nature acts as a complete entity, with all that is in it, consciously or unconsciously; and though it may be wrong, it's nevertheless alive.
Fyodor DostoevskyBut it is possible, it is possible: the old grief, by a great mystery of human life, gradually passes into quiet, tender joy; instead of young, ebullient blood comes a mild, serene old age: I bless the sun's rising each day and my heart sings to it as before, but now I love its setting even more, its long slanting rays, and with them quiet, mild, tender memories, dear images from the whole of a long and blessed life--and over all is God's truth, moving, reconciling, all-forgiving!
Fyodor Dostoevsky
