Analytic philosopher and logician. He inherited the philosophy of the Greeks (the stoics, sophists and Aristotle) and the Brits (Ockham, Locke, Hobbes and Hume). He was a pupil of Russell. His main idea was that language underpins everything. The logical structure of human language is identical to the ontological structure of the world, since it’s only language that really describes everything around us. He argued that nothing outside of logic and material facts makes any sense. Whilst religion, ethics and aesthetics might help society function, they are essentially mystical concepts and can’t be used as the basis for any ontological idea.
