What did descartes invent?

Answer 1

Rene Descartes was an inventor but far from that he was a philosopher. He devised the theory Cogito Ergo Sum which translates from Latin into English as I think, therefore I am. This statement which he himself conjured up and is his most notable achievement has been designated to proving certainty. Descartes believes that through skepticism certainty can be produced. He states that nothing in the universe can be proven beyond doubt; however he also states that doubt is none other than thought and that thought is none other than the mind. SO therefore the only thing that can be proven beyond doubt is the mind. Along with this he came up with the notion that if we as imperfect beings were created by some outside force, then that outside force has to be designed as a perfect entity. Thus it was the perfectibility of an outside force-namely God- that placed this imperfect knowledge within us. He is considered the father of modern philosophy mainly because he was the first individual who indicated that certainty exists in our world. He contributed in the area of optics as well as physics. He created the Cartesian coordinate system(which is still in use today); he founded analytical geometry alongside a colleague of his. He was one of the earliest dualists, indivudals who believed mind was separate from matter. He influenced future scholars and philosophers such as Kant, Locke, and Hobbes. Overall he was an overachiever, a brilliant mind, who brought many things to the world during the time of the enlightenment.
René Descartes was a French philosopher, mathematician, and writer who spent most of his adult life in the Dutch Republic. He has been dubbed the 'Father of Modern Philosophy', and much subsequent Western philosophy is a response to his writings, which are studied closely to this day. In particular, his Meditations on First Philosophy continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system - allowing algebraic equations to be expressed as geometric shapes, in a 2D coordinate system - was named after him. He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution.
