Most Famous Rationalism Philosophers

Rationalism is the philosophical view that reason is the chief source and test of knowledge. Its leading early modern proponents, Descartes, Spinoza, and Leibniz, held that the mind possesses innate ideas or principles from which substantive truths about reality can be derived. Rationalists typically grant mathematics a privileged status as a model of certain knowledge. The position contrasts with empiricism, which traces knowledge to sense experience. The seventeenth-century rationalist program shaped both modern philosophy and the foundations of mathematical physics.
