Abstract
This paper is an application of Max Weber’s thesis about the “elective affinity” between Protestant religious impulses and the rise of capitalism, and rationalization of benevolence. Exploring the history of organized philanthropy in the United States, using the life and work of John D. Rockefeller, the paper presents the power of the religious motive in Rockefeller’s commitment to philanthropy, especially towards support for scientific university based research in medicine. Presenting historical evidence, the paper argues against those who see U.S. philanthropists as giving out of guilt or for selfish motivation, and those who critique philanthropic foundations as producers and reproducers of cultural hegemony.
