Showing results for "The Principles" in History

By calling everything into doubt, Descartes laid the foundations of modern philosophy. With the celebrated words "I think therefore I am," his compelling argument swept aside ancient and medieval traditions. He deduced that human beings consist of minds and bodies; that these are totally distinct "substances"; that God exists and that He ensures we can trust the evidence of our senses.

With his feet firmly on the ground, he challenged the speculative ideas of David Hume and George Berkeley who regarded ideas in the mind as a basis for the external world. Instead, the pugnacious but lively Reid took a much more ‘common sense’ view in basing his ideas of reality on sensus communis. Starting from a Ciceronian, stoical platform, he developed his views on more rational attitudes towards reality - ‘direct realism’.
