CAFNtoon: Cogito Ergo Sum


by Peter Ellerton

“I have convinced myself that there is absolutely nothing in the world, no sky, no earth, no minds, no bodies. Does it now follow that I too do not exist? No: if I convinced myself of something then I certainly existed. But there is a deceiver of supreme power and cunning who is deliberately and constantly deceiving me. In that case I too undoubtedly exist, if he is deceiving me; and let him deceive me as much as he can, he will never bring it about that I am nothing so long as I think that I am something. So after considering everything very thoroughly, I must finally conclude that this proposition, I amI exist, is necessarily true whenever it is put forward by me or conceived in my mind.” (Med. 2, AT 7:25)

Nugget: Kant’s Rational Empiricism


Kant’s Rational Empiricism: His R.E. is the combination of Rationalism of Rene Descartes and Empiricism of John Locke and David Hume. Kant argues true knowledge is more than simply a blank tablet, as Descartes suggest it as tabula rasa, that received information from our external sense experience. It also processes the data that is received from our sense experience and classifies them accordingly to their categories in the mind which he believes to be innate and inherent.
