Abstract

Here I will explore through a literature review three important but different ways in which skepticism has been developed. The first is that of the Gettier problem and its potentially skeptical implications for knowledge. The second is Agrippa’s Trilemma, in which the non-skeptic ostensibly struggles to develop a satisfactory account of epistemic justification. Third and lastly, there are brain-in-a-vat scenarios, as one attempts to meet the skeptic’s challenge of having knowledge of the external world. I conclude that the above are important challenges while still maintaining that the non-skeptic has formulated responses worth our consideration.
