"[1] This essay has been described as "the most systematic and fully developed" and even "the seminal theoretical treatment of generations as a sociological phenomenon".
[2] 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.
[2][6] A key point, however, is that this major historical event has to occur, and has to involve the individuals in their young age (thus shaping their lives, as later experiences will tend to receive meaning from those early experiences); a mere chronological contemporaneity is not enough to produce a common generational consciousness.
[2] Mannheim's theory of generations has been applied to explain how important historical, cultural, and political events of the late 1950s and the early 1960s educated youth of the inequalities in American society, such as their involvement along with other generations in the Civil Rights Movement, and have given rise to a belief that those inequalities need to be changed by individual and collective action.
[6] On the other hand, the generation which came of age in the later part of the 1960s and 1970s was much less engaged in social movement activity, because - according to the theory of generations - the events of that era were more conducive to a political orientation stressing individual fulfillment instead of participation in such social movements questioning the status quo.
