Chapter III: Sleep And Death

The picture we have thus been painting of a world imperceptible to the outer senses may seem less incredible if one will look with open mind at well-known aspects of the animal creation.

Even if man had no organs to perceive this outer form, he would still have to recognize the wolf's existence if the cravings, though invisible, made themselves felt in their effect—if there were on the prowl a power invisible to human eye, yet by whose agency all that the visible wolf is doing were being done.
