Abstract
This paper explores a fundamental issue in epistemology, namely, that the world is completely different in general from the way our sensory impacts and our internal makeup lead us to believe (Stroud 1994). Three hypotheses are considered: first, that there is something like an independent external reality; second, that the epistemic relationship occurring between this reality and the knowing subject is somehow such as not to allow the latter to know the intrinsic nature of the former; and finally, that the human knower has a spontaneous desire to know what the intrinsic nature of external reality is.
