Descartes refers to "the long-standing opinion that there is an omnipotent God who made me the kind of creature that I am" and suggests that this God may have "brought it ...
The Dream Argument questions Aristotelian epistemology, while the Evil Demon Argument does away with it altogether.

The " five minute hypothesis ", most notably proposed by Bertrand Russell , suggests that we cannot prove that the world was not created five minutes ago (along with false memories and false evidence suggesting that it was ...
