In 1914, when Freud wrote a preface to the third edition of the Three Essays on Sexuality, he baldly stated that the human “... disposition is ultimately the precipitate of earlier experience of the species. Carrying inside them the cumulative weight of evolution, the child is driven by archaic, perverse impulses. In civilized societies, these forces were hidden and rendered unconscious. But under the veneer of progress, there lay a primal sexual force that was vital to life itself.” For years afterward, Freud would look to children, savages, and primitives, arguing that they all lived free from repression. In these beings, one could circumvent the problems of knowing what was normally forgotten and impossible to appre- hend with interior observation. In them it was possible to grasp the mystery of the unconscious. This position was plausible only because Freud and many of his readers, following the famed biologist Ernst Haeckel, believed that all human history lay somewhere in our minds (2008, pp. 117–118).
