 It was, after all, a Greek living less than two and a half millennia ago within such a sedentary, hierarchically organised population structure, who could have had no conception of the prehistory of the beings he called anthrôpoi, whose thoughts on their “nature” have been decisive for the history of philosophical reflection on the subject. It seems highly likely that, without the influence of Aristotle, discussions of “human nature” would not be structured as they are until today.
