We might think that appearances give a prima facie justification for belief. This is the foundation for Phenomenal Conservatism in epistemology. McCain and Moretti adapt this view by integrating it with the view that epistemic justification is a matter of explanatory relations between one's evidence and propositions supported by that evidence.
Appearance and Explanation: Phenomenal Explanation in Epistemology offers an engaging epistemological search for a complete theory of epistemic justification. The book is organized in three parts. The first explores what Michael Huemer characterized as phenomenal conservativism, the theory that one ought to believe that things are as they appear in absence of reason to think otherwise...Parts 2 and 3 explore McCain and Moretti's theory of phenomenal explanation, which builds on phenomenal conservativism in an attempt to construct a complete theory of epistemic justification. Part 2 provides a clear exploration of the theory, and part 3 defends the theory from criticism. Although technical and rigorous, this book is clear and accessible throughout.
