Comments on appearance and explanation

So as I understand it, the fundamental goal of Kevin McCain and Luca Moretti’s Appearance and Explanation is to offer a unified account of epistemic justification, one that incorporates insights of both phenomenal conservatism and explanationism. One might suppose that one gets the best of both views by employing the phenomenal conservative’s views about the role of appearance in order to get the initial data that needs explaining, while one appeals to explanationism to expand one’s justified beliefs beyond the data provided by appearance. But if I understand the authors, their view may be more complicated than this. While McCain and Moretti defend many views with which I agree in Appearance and Explanation, I’ll focus here on questions and objections. The first concerns the role of appearance in giving one an explanandum. The second concerns the role of appearance in reaching justified beliefs about whether a proposed explanation is better than alternatives.
