This document provides an overview of sociologist Max Weber's key ideas. It summarizes Weber's focus on the relationship between culture/worldviews and economics, and his argument that secular capitalism has religious and cultural origins, as outlined in his book The Protestant Ethic and the Spirit of Capitalism. Specifically, Weber argued that Protestant beliefs like Calvinism encouraged the values of hard work, asceticism, and profit accumulation that helped give rise to the spirit of modern capitalism.
