Please answer the following questions that are in bold down below:

1.If the foundations of a house are poorly made, or are set on unstable ground, what might happen to that house? So by analogy for Descartes, if the foundations of our beliefs are doubtful, what might happen to our whole house of beliefs?

2.As mentioned in my notes, our author compares Descartes worries that there might be an Evil Genius to the plot of that vastly overrated movie The Matrix. Here is the point of the comparison, which helps to illuminate what Descartes means by this Evil Genius: how can you, or I, or anyone be sure that their mind is not being manipulated by someone or something they are quite unaware of? If you cant be sure, then for Descartes, everything you believe might be false. Except, of course, for that one certainty he claims he discovers, that he exists. So you can imagine someone in a Matrix-like situation who could do what Descartes did, arrive at the certainty of his own existence. But here is a question for you: what good, in that situation, would that do for him?
