William Of Ockham
William of Ockham was a 14th-century English philosopher and theologian, best known for his principle of parsimony, often referred to as Ockham's Razor. This principle suggests that the simplest explanation, or the one that makes the fewest assumptions, is usually the correct one. Ockham's ideas significantly influenced the development of medieval philosophy and scientific reasoning.
Ockham was a member of the Franciscan Order and engaged in debates about the nature of universals, which are concepts that can apply to multiple instances. His work laid the groundwork for later thinkers, including Rene Descartes and David Hume, and he is often regarded as a precursor to modern empiricism.
