Theory of generations

Theory of generations (or sociology of generations) is a theory posed by Karl Mannheim in his 1928 essay, "Das Problem der Generationen," and translated into English in 1952 as "The Problem of Generations." This essay has been described as "the most systematic and fully developed" and even "the seminal theoretical treatment of generations as a sociological phenomenon". According to Mannheim, people are significantly influenced by the socio-historical environment (in particular, notable events that involve them actively) of their youth; giving rise, on the basis of shared experience, to social cohorts that in their turn influence events that shape future generations. Because of the historical context in which Mannheim wrote, some critics contend that the theory of generations centers on Western ideas and lacks a broader cultural understanding. Others argue that the theory of generations should be global in scope, due to the increasingly globalized nature of contemporary society.
