I have not been able to do more than touch upon the principal features of this book, the fame of whose brilliant author has long spread beyond the boundaries of his own native country. Emil Lucka was born in Vienna in 1877, and has already achieved a number of remarkably fine books, most of which have been translated into Russian, French, and other foreign languages. He is as yet unknown in England, this being the first of his works to appear in English. ELLIE SCHLEUSSNER. FOOTNOTE: [1] _cf._ Hartland's "Primitive Paternity" and Frazer's "Golden Bough." THE EVOLUTION OF LOVE THE FIRST STAGE: THE SEXUAL INSTINCT To the generations slowly rising from the dark abyss of time to the twilight of the Middle Ages, the satisfaction of the sexual instinct offered fewer difficulties than the gratification of any other need or desire. With every unpremeditated and cursory indulgence the craving disappeared from consciousness and left the individual free to give his mind to the acquisition of the necessities of life which were far more difficult to obtain. Primitive, prehistoric man lived in the moment. When there was plenty of food he gorged to repletion, heedless of the starvation which might be his fate to-morrow or the day after. His thought had neither breadth nor continuity. It never occurred to him that there might be a connection between an abrupt and quickly forgotten embrace and the birth of a child by a woman of the tribe after what appeared to be an immeasurable lapse of time. He suspected witchcraft in the phenomena of pregnancy and childbirth (to this day the aborigines of Central and Northern Australia do not realise the connection between generation and birth). As a rule it was remembered that a certain woman had given birth to a certain child by the fact of her having carried it about and fed it at her breast. Occasionally it was forgotten to which mother a child belonged; perhaps the mother had died; perhaps the child had strayed beyond the boundaries of the community and the mother had failed to recognise it on its return. But it was clear beyond all doubt that every child had a "mother." The conception of "father" had not yet been formed. Experience had taught our primitive ancestors two undeniable facts, namely "that women gave birth to children" and "that every child had a mother."
