“It is when we try to grapple with another man's intimate need that we perceive how incomprehensible, wavering and misty are the beings that share with us the sight of the stars and the warmth of the sun. It is as if loneliness were a hard and absolute condition of existence; the envelope of flesh and blood on which our eyes are fixed melts before the outstretched hand, and there remains only the capricious, unconsolable and elusive spirit that no eye can follow, no hand can grasp.”
