Abstract
For the past several years I have worked out what has become “the logic of species”Logiclogic of species by taking up the issue of the logic of social beingThe Logic of Social Being. My reasons for undertaking this are, in short, two: the practical and the logical. In the first case, I have come to believe that the ethnic unity and coercive power of the state, which have arisen together quite recently in various countries, include an element that can hardly be comprehended from the standpoint that tries to consider society as nothing but the reciprocal relation of individuals.
