    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.
