Michael Huemer: Skepticism and Direct Realism | WSB #31

March 13, 2018

Do we have any reason to doubt appearances? And does perception show us intermediary mental representations or real objects themselves?

Michael Huemer's first book, Skepticism and the Veil of Perception, tackles both these questions at once. Huemer is a direct realist: he thinks that when we perceive, we're perceiving reality directly. This contradicts the common philosophical position ("indirect realism") that our perception is of mental objects which are images or representations of real objects to which we have no direct access. The usual challenges against direct realism involve an appeal to illusion and hallucination, though Huemer argues that these are less problematic than is often suggested. Huemer also argues that a direct realism (along with a correct general approach to epistemology) helps refute the famous skeptical arguments: the infinite regress of justification (the "Agrippan trilemma"), the "problem of the criterion", the famous brain in the vat, and Hume's argument against the possibility of induction.
