What happened
Rene Descartes, born in 1596, published the Meditations on First Philosophy in Latin in 1641, with six sets of objections from other thinkers and his own replies included in the same volume. Descartes's method was to treat as false any belief that admitted even the slightest doubt, stripping away sensory belief, mathematical belief, and even the belief that he had a body, until he reached one claim that survived the doubt itself: that the very act of thinking proved his own existence, summarized in the phrase cogito, ergo sum, I think, therefore I am. From that foundation Descartes argued that mind and body are really distinct substances, the mind essentially a thinking thing and the body essentially an extended, divisible thing, a position that created what is still called the mind-body problem.
Why it matters
The Meditations relocated the starting point of philosophy from external authority, whether Aristotle or scripture, to the individual thinker's own certainty, making Descartes a founding figure of modern rationalism and setting the mind-body relationship as a central problem that later philosophy of mind has never fully closed.
How we know
The Meditations survives complete in its original 1641 Latin edition alongside the objections and replies exchanged with contemporary critics including Hobbes and Arnauld, giving historians a documented record of how Descartes's contemporaries responded to the argument as it was published.
