Pierre de Fermat
The phrase you are referring to is actually "Cogito, ergo sum," which translates to "I think, therefore I am." This famous philosophical statement was made by René Descartes, a French philosopher and mathematician, rather than a mathematician in the conventional sense. Descartes is widely recognized for his contributions to philosophy, mathematics, and the development of Cartesian coordinates.
