Who was pitirim sorokin?

Pitirim Sorokin (1889–1968) was a prominent Russian-American sociologist known for his extensive work on social theory, cultural change, and the study of altruism.

Here are a few key points about his life and work:

• Early Life and Exile: Born in Russia, he was involved in revolutionary politics and was imprisoned by both the Tsarist and Bolshevik regimes. He was eventually exiled by the Soviet government in 1922, moving first to Czechoslovakia and then to the United States.
• Academic Career: He settled at Harvard University, where he founded the Department of Sociology in 1930 and served as its first chairman.
• Sociological Contributions: He is perhaps best known for his massive, four-volume work, Social and Cultural Dynamics, in which he analyzed the cyclical nature of civilizations, arguing that cultures oscillate between "sensate" (materialistic) and "ideational" (spiritual/intellectual) states.
• Focus on Altruism: Later in his career, he became deeply interested in the study of "creative altruism" and love, establishing the Harvard Research Center in Creative Altruism in 1949. He believed that the systematic study of unselfish love was essential for the survival of modern society.

His work is often characterized by a broad, historical scope that sought to identify long-term patterns in human society rather than just immediate social issues.
