Discover Descartes' method of doubt: the radical skepticism that challenged dogmatism and changed philosophy forever. Learn how questioning everything led to "I think, therefore I am" and why this 17th-century method remains essential for critical thinking in our age of misinformation and fake news.

Join us as we explore Descartes's philosophical revolution which is listed amongst the likes of Newton and Copernicus. Descartes, a Rationalist, sought to rebuild knowledge on the foundation of reason alone, famously using his method of Cartesian Doubt to discard uncertain beliefs making him an extremist Socratic reincarnation. We delve into his Meditations 6, particularly his exploration of the mind-body problem, where he argued for the distinct, yet interacting, substances of mind (res cogitans) and body (res extensa). We also look at criticisms of Descartes’ Dualism by figures like Princess Elizabeth and Gilbert Ryle, who mockingly called it the “Dogma of the Ghost in the Machine.”
