William Hamilton

William Hamilton was a Scottish philosopher and logician in the 19th century, best known for his work on metaphysics and the philosophy of mind. He advocated for "common sense philosophy," emphasizing that common beliefs and perceptions should guide our understanding of reality. Hamilton also contributed to the study of logic, particularly in formal reasoning. His ideas influenced later thinkers, including the development of modern psychology and epistemology. Notably, he introduced the concept of "the principle of sufficient reason," suggesting that everything must have a reason or explanation behind it. His work remains significant in philosophy today.
