The French Liar

The French philosopher René Descartes (1596-1650) is generally presented as one of the founders of modern Western philosophy and science, the man who made reason the principle of the search for truth, and who formulated the cogito, ‘I think, therefore I am.’ His assertion of mind-body dualism has given rise to a great number of objections over time, from those of 17th-century theologians to those of 20th-century feminists. In France, even though the decision of the 1792-95 National Convention to transfer Descartes’s remains to the Pantheon in Paris was not followed through, the philosopher is nonetheless regarded as ‘un grand homme’, a national hero, and being labelled ‘Cartesian’ is still today a compliment that emphasises one’s common sense, good judgment and methodical use of reason.
