dationalism, idealism, and pallibalism all fit together to prove that Neo can not be certain of the matrix, but only himself. Also it further explains how it is rational for him to believe that the matrix exists through his perception of the matrix and the knowledge he obtains when he is there. The growth of knowledge in Neo’s mind is possible what is his deception. The more he perceives could possible be more he is deceived. What we know about reality is all in our minds and if we can only be certain of ourselves and our own existence then the reality that we perceive and conceive does exist. So the answer is yes, Neo can know that he is in the matrix, but this does not necessarily mean the matrix exists. As far as Neo knows the matrix does exist and that he will return to what he thought was his reality later, knowing that there is more than just his world....
