Alyosha emerged from the dream transformed. Something burned in his heart, something suddenly filled him almost painfully, tears of rapture nearly burst from his soul. ...Over him the heavenly dome, full of quiet, shining stars, hung boundlessly. From the zenith to the horizon the still-dim Milky Way stretched its double strand. Night, fresh and quiet, almost unstirring, enveloped the earth. The silence of the earth seemed to merge with the silence of heavens, the mystery of the earth touched the mystery of the stars. ...Alyosha felt clearly and almost tangibly something as firm and immovable as the heavenly vault descend into his soul. ...Never in his life would he forget that moment.
~ from THE BROTHERS KARAMAZOV by Fyodor Dostoevsky
This is essentially the argument for the soul: it holds reality together, it is my offscreen director, my presiding intelligence. I can think, talk, work, love, and dream, all because of the soul, yet the soul doesn't do any of these things. It is me... Everything that makes the difference between life and death must cross into this world via the soul... Soul is a connection between the world of the five senses and a world of inconceivable things like eternity, infinity, omniscience, grace, and every other quality unmanifest.
