"The law of heredity teaches that mental and morphological impressions are transmitted to the offspring from the sexes. In the same way intuitions arise from the gestation of thought, the continuity of which is transmitted by the same means, and for which we are indebted not only to our parents, but to all our progenitors. He who possesses genius can emit coruscations from the gestation of thought which are the evolutionary flashings of a spiritual essence." ["Origin, Purpose and Destiny of Man," by Wm. Thornton].
