বাঙালির সামাজিক পরিচয় ও বিবর্তন

Abstract

‘‘The Law of social evolution is the law of all evolution. Whether it be in the development of the Earth, in the development of life upon its surface, in the development of society, of Government, of Manufactures, of commerce, of Language, Literature, science, Art, this same advance from the single to the complex through successive differentiations, holds uniformly.’’^১
