86:5.1
The nonmaterial part of man has been variously termed ghost, spirit, shade, phantom, specter, and latterly soul. The soul was early man’s dream double; it was in every way exactly like the mortal himself except that it was not responsive to touch. The belief in dream doubles led directly to the notion that all things animate and inanimate had souls as well as men. This concept tended long to perpetuate the nature-spirit beliefs; the Eskimos still conceive that everything in nature has a spirit.
