These are six meditations by the French philosopher Rene Descartes, best known for his conclusion "Cogito, ergro sum" "I Think, therefore I exist". They are called meditations because he clearly describes his deep reasoning on each topic. Each topic has objections made by Thomas Hobbs and Descartes' responses. The six topics are [i]Of Things Doubtful.[/i]; [i]Of the Nature of Mans Mind, and that ’tis easier Proved to Be then our Body[/i]. ; [i]Of God, and that there Is a God.[/i] [i]Of Truth and Falsehood.[/i]; [i] Of the Essence of Things Material, and herein again of God, and that He does Exist.[/i]; . [i]Of Corporeal Beings and their Existence, as also of the Real Difference between Mind and Body[/i]. (Summary by phil chenevert)[/quote]
