kartéziuszi

Kartéziuszi refers to anything related to René Descartes, a prominent 17th-century French philosopher, mathematician, and scientist. His work is foundational to modern philosophy, particularly in the areas of epistemology and metaphysics. A key concept associated with him is Cartesian doubt, a systematic process of doubting everything that can be doubted to arrive at certain knowledge. This led to his famous statement, "Cogito, ergo sum" (I think, therefore I am), which he considered an indubitable truth.

Descartes is also known for Cartesian dualism, the idea that the mind (res cogitans) and the body (res extensa) are distinct substances. This distinction has had a profound impact on subsequent philosophical and scientific thought. In mathematics, his name is linked to the Cartesian coordinate system, which uses perpendicular axes to represent points in space algebraically. This invention revolutionized geometry by allowing algebraic methods to be applied to geometric problems, bridging the gap between these two fields. His rationalist approach emphasized reason as the primary source of knowledge, contrasting with empiricism. The term "kartéziuszi" encompasses his philosophical method, his metaphysical theories, and his mathematical contributions.
