To-day we feel for such a thing nothing but the deepest abhorrence, and never would admit it still slumbered in our souls. Nevertheless, just as truly as the idea of the sexual assault is there, so are these things there too; which we should contemplate still more closely,—not through moral eye-glasses, with horror, but with interest as a natural science, since these things are venerable relics of past culture periods. We have, even to-day, a clause in our penal code against sodomy. But that which was once so strong as to give rise to a worship among a highly developed people has probably not wholly disappeared from the human soul during the course of a few generations. We may not forget that since the symposium of Plato, in which homo-sexuality faces us on the same level with the so-called “normal sexuality,” only eighty generations have passed. And what are eighty generations? They shrink to an imperceptible period of time when compared with the space of time which separates us from the homo-Neandertalensis or Heidelbergensis. I might call to mind, in this connection, some choice thoughts of the great historian Guglielmo Ferrero:[48] “It is a very common belief that the further man is separated from the present by time, the more does he differ from us in his thoughts and feelings; that the psychology of humanity changes from century to century, like fashions of literature. Therefore, no sooner do we find in past history an institution, a custom, a law or a belief a little different from those with which we are familiar, than we immediately search for some complex meanings, which frequently resolve themselves into phrases of doubtful significance. “Indeed, man does not change so quickly; his psychology at bottom remains the same, and even if his culture varies much from one epoch to another, it does not change the functioning of his mind. The fundamental laws of the mind remain the same, at least during the short historical period of which we have knowledge, and all phenomena, even the most strange, must be capable of explanation by those common laws of the mind which we can recognize in ourselves.”
