In this article the author is going to prove that all the data of recent decades obtained in the field of neurophysiology, linguistics, logic, semiotics and anthropology prove that the idea of a unite Human Nature, which was postulated by the Enlightenment, is not a fiction or even "abstraction", but a perfectly recognizable (though nondescript) reality. All humans are the same, and human nature does not depend on culture. However, the paper addresses not so much the data as their consequences. The universal Human Nature implies the existence of uniform standards of thinking and behavior (ethics), unaffiliated with historical experience, traditions, and beliefs. These standards are available to everyone. But they are unevenly implemented in various cultures due to various historical circumstances.
Justification of human nature. Universalism and cultural diversity from the point of view of modern science
