viii. The Hyperborean and the Polarean Epoch

One must imagine the perceptual world of these ancestors of man to have been a quite general and indefinite one. Only two of the types of perception of today had already become separated: the sense of hearing and the sense of touch. Because of the changes that had taken place in the body as well as in the physical environment, the entire human form was no longer capable of being, in a manner of speaking, an “ear.” A special part of the body remained capable of reverberating to delicate vibrations. It furnished the material from which our organ of hearing gradually developed. However, approximately the whole remainder of the body continued to be the organ of touch.
