About Richard Avenarius
Richard Ludwig Heinrich Avenarius (born Richard Habermann; 19 November 1843 – 18 August 1896) was a French-born German-Swiss philosopher. He formulated the radical positivist doctrine of "empirical criticism" or empirio-criticism. Avenarius believed that scientific philosophy must be concerned with purely descriptive definitions of experience, which must be free of both metaphysics and materialism. Avenarius' principal works are the famously difficult Kritik der reinen Erfahrung (Critique of Pure Experience, 1888–1890) and Der menschliche Weltbegriff (The Human Concept of the World.
