The meaning of philosophy to me is not only in its principles, but also in the happy isolation of its great expounders. They were seldom of the world, even when like Plato and Leibnitz they moved in its courts and drawing-rooms. To the tumult of life they were deaf, and they were blind to its distraction and perplexing diversities. Sitting alone, but not in darkness, they learned to find everything in themselves, and failing to find it even there, they still trusted in meeting the truth face to face when they should leave the earth behind and become partakers in the wisdom of God. The great mystics lived alone, deaf and blind, but dwelling with God.
I understand how it was possible for Spinoza to find deep and sustained happiness when he was excommunicated, poor, despised and suspected alike by Jew and Christian; not that the kind world of men ever treated me so, but that his isolation from the universe of sensuous joys is somewhat analogous to mine. He loved the good for its own sake. Like many great spirits he accepted his place in the world, and confided himself childlike to a higher power, believing that it worked through his hands and predominated in his being. He trusted implicitly, and that is what I do. Deep, solemn optimism, it seems to me, should spring from this firm belief in the presence of God in the individual; not a remote, unapproachable governor of the universe, but a God who is very near every one of us, who is present not only in earth, sea and sky, but also in every pure and noble impulse of our hearts, "the source and centre of all minds, their only point of rest."
Thus from philosophy I learn that we see only shadows and know only in part, and that all things change; but the mind, the unconquerable mind, compasses all truth, embraces the universe as it is, converts the shadows to realities and makes tumultuous changes seem but moments in an eternal silence, or short lines in the infinite theme of perfection, and the evil but "a halt on the way to good." Though with my hand I grasp only a small part of the universe, with my spirit I see the whole, and in my thought I can compass the beneficent laws by which it is governed. The confidence and trust which these conceptions inspire teach me to rest safe in my life as in a fate, and protect me from spectral doubts and fears. Verily, blessed are ye that have not seen, and yet have believed.
