“In the writings of a recluse one always hears something of the echo of the wilderness, something of the murmuring tones and timid vigilance of solitude; in his strongest words, even in his cry itself, there sounds a new and more dangerous kind of silence, of concealment. He who has sat day and night, from year's end to year's end, alone with his soul in familiar discord and discourse, he who has become a cave-bear, or a treasure-seeker, or a treasure-guardian and dragon in his cave—it may be a labyrinth, but can also be a gold-mine—his ideas themselves eventually acquire a twilight-colour of their own, and an odour, as much of the depth as of the mould, something uncommunicative and repulsive, which blows chilly upon every passer-by.”
