         Fechner affords a conspicuous instance of the
         idealistic tendency to mysterize nature in his
         panpsychicism, or that form of noumenal idealism which
         holds that the universe is a vast communion of spirits,
         souls of men, of animals, of plants, of earth and other
         planets, of the sun, all embraced as different members
         in the soul of the world.                --Encyc. Brit.
