In lower states of human love these spiritual elements are undoubtedly wanting. Amongst primitive men the manifestations of sexuality can have differed in no wise from those of the animals most nearly related to them. Their love was still a pure animal instinct. The Asiatic myth which divided the earliest periods of human history in this way, asserting that the inhabitants of paradise loved for thousands of years merely by means of glances, later by a kiss, by simple physical contact, until ultimately they underwent a “fall” through adopting the debased methods of common animal sexual indulgence--this infantile mythology would be accurate enough if one inverted the series of stages in the evolution of love. This view is confirmed by the fact that, according to the most recent investigation into the history of primitive man, it is extremely probable that to palæolithic man of the earlier diluvial period the idea of the spiritual was still completely unknown--that palæolithic man was, in fact, purely a creature of impulse--an opinion already maintained by Darwin in his work on the “Descent of Man.” In the sexual instinct, above all, every dualistic division into physical and spiritual was entirely foreign to primitive man. The more primitive the state of civilization, the less is the idea “love” known, a fact first established by Lubbock. Even at the present day, in regard to this matter, there is a notable difference between the upper and the lower classes in a European civilized community. For example, Elard Hugo Meyer, in his excellent “Deutsche Volkskunde” (“German Folk-lore,” p. 152; Strasburg, 1898), states that from Eastern Friesland to the Alps amongst the common people the word “love,” to us so indispensable and so exalted, is entirely unknown; in its place words expressing rather the sensual side of the impulse are employed.
