a dry psyche is most skilled

“The stuff of the psyche is a smoke-like substance of fine particles that give rise to all other things, particles of less mass than any other sustance and constantly in motion: only movement can know movement. . . . The psyche rises as a mist from things that are wet. . . . A dry psyche is most skilled in intelligence and is brightest in virtue. . . . A drunk man, staggering and mindless, must be led home by his son, so wet is his psyche.”
