 CP2 claims that we are not justified in denying the skeptical hypothesis—in other words, that we are not justified in believing that we are not being deceived. What arguments can be given for CP2? It is tempting to suggest something like this: The skeptical scenarios are developed in such a way that it is assumed that we could not tell that we were being deceived. For example, we are asked to consider that there is an Evil Genius “so powerful” that it could (1) make me believe that there were hands when there were none and (2) make it such that I could not detect the illusion. But the skeptic must be very careful here. She cannot require that in order for S to know (or be justified in believing) something, say x, that if x were false, she would not still believe x. We have just seen (while examining Nozick’s account of knowledge) that this requirement is arguably too strong. So the mere fact that there could be skeptical scenarios in which S still believes that she is not in such a scenario cannot provide the skeptic with a basis for thinking that she fails to know that she is not (actually) in a skeptical scenario. But even more importantly, were that a requirement of knowledge (or justification), then we have seen that closure would fail and, consequently, the basis for the first premise in the CP-style argument for Cartesian Skepticism would be  forfeited.[12]
