David Armstrong

David Armstrong was an influential philosopher known for his work in metaphysics, particularly regarding universals and particulars. He argued for "realism" about universals, meaning he believed that properties like "redness" exist beyond individual objects. Armstrong also supported physicalism, the idea that everything is ultimately physical, influencing debates on mind and body. His functionalism approach in the philosophy of mind suggested that mental states can be understood in terms of their functions rather than their physical makeup. This perspective paved the way for modern discussions about the relationship between mind, body, and the nature of reality.
