"Just as native material life is an adaptation—not obvious or easily got but carefully worked out with the experience of thousands of years—to the conditions of river and forest, wearing the loincloth, as I have tried to show in passing, is a small part of a psychological adaptation in human life, in which male sexuality is neither repressed or vilified, but asserted, and at the same time humanized. It would be a pity if this as other human achievements were allowed to be lost to the world."
I think there is a message for us here in this text.
