Unlike most mammals Homo sapiens cannot be called either a gregarious or an individual animal. Man lives in collectives that are regarded, depending on the point of view, sometimes as a socium, sometimes as an ethnos. Or rather each human being is simultaneously a member of a society and a representative of an ethnic national group, but these two concepts are incommensurable and lie on different planes, like length and weight, for example, or a degree of heat and an electrical charge.
