A critical review of the theory of cultural relativism by M. J. Herskovits, who made an attempt to formulate an objective criterion to estimate phenomena of foreign cultures, is presented.

However it was of special importance in fighting against ethnocentrism, thus stimulating research in- values at intercultural aspect.
