Gaunilo of Marmoutiers's Criticisms

A Level: AQA • Edexcel • OCR • WJEC

A detailed investigation into Gaunilo of Marmoutiers's famous criticisms of the ontological argument, including how they work, and why they're convincing. This lesson provides a brief biography of Gaunilo of Marmoutiers, and covers the text of In Behalf of the Fool. This includes discussion of the analogy of the lost island, and how it's used to reduce the ontological argument for the existence of God to absurdity.
