25 Rene Descartes Quotes (About Life, Self, Math…)

René Descartes was a world-renowned French philosopher, scientist, writer, and mathematician who is widely considered as the Father of Analytical Geometry, as well as the Father of Modern Philosophy. He is also recognized as one of the most celebrated intellectual figures of the Dutch Golden Age.

His theories, works, and writings are still being applied to this day, and a lot of principles in Western philosophy have come as a result of his writings. Descartes’ influence in mathematics is relatively clear—after all, his work in mathematics helped establish the Cartesian coordinate system which allowed algebraic equations to be expressed as geometric shapes.

His most significant philosophical statement is “I think, therefore I am.” He also set his views apart from those of his predecessors and refused to accept the authority of former philosophers. His books and writings especially the “Meditations on First Philosophy” is still considered as a bible in most Philosophy departments in numerous universities.

Here’s a list of some of the most notable quotes by René Descartes that explores his thoughts and views regarding life, mathematics, philosophy, and more.
