Hungarian-Jewish born sociologist Karl Mannheim (March 27, 1893, Budapest, Hungary–January 9, 1947, London, United Kingdom) was one of the founders of the discipline known as the sociology of knowledge. His “Ideology and Utopia” has endured as a classic of social science. Mannheim’s contributions to the understanding of generations as social, political, intellectual phenomena are utterly timely. The transmission of cultural constructs, memories, and significant reference points (what Mannheim called “the accumulated cultural heritage”) is the guarantee that humanity can overcome oblivion and amnesia. Each generation has its differentia specifica, yet none is totally devoid of visible or invisible links to the previous ones.
