Continental Rationalism

'Continental Rationalism'\ is a philosophical creed that human reason is the source of knowledge. It originated with Rene Descartes and spread during the 17th and 18th centuries, primarily in continental Europe. In contrast, its contemporary rival, the British Empiricists held that all knowledge comes to us through experience or through our senses. At issue is the fundamental source of human knowledge, and what the proper techniques are for verifying what we think we know. (See Epistemology.)

Rationalists argued that starting with intuitively-understood basic principles, like axioms of geometry, one could deductively derive what was true. Descartes, with his mathematical background, was naturally drawn toward this method, and famously claimed to derive his own existence from pure reason (cogito, ergo sum). On the heels of his work came continental philosophers such as Spinoza and Leibniz who sought to enlarge and refine the fundamental theory of rationalism.

Immanuel Kant started as a rationalist, but after being exposed to David Hume's works which "awoke [him] from [his] dogmatic slumbers", Kant arguably synthesized the rationalist and empiricist traditions.

Rationalism may also be used to refer to a philosophy that human behaviour and values should be based primarily on rationality, as opposed to emotion or dogma.
