Philosophy, Science, and Common Sense

Wilfrid Sellars recognized a conflict between what he called “the scientific image” of our place in the world, and “the manifest image.” Sellars sought, somehow, to join these views together in spite of their apparent conflict. This chapter argues that we should endorse features of the manifest image only to the extent that they are part of the scientific image. It presents a case study in epistemology, showing how these issues play out in discussion of doxastic deliberation. The manifest image of such deliberation is flatly in conflict with the best current scientific theorizing about the nature of deliberative processes. The only reasonable response to such conflict, the chapter argues, is to embrace the scientific account and reject our first-personal view of deliberation as illusory. This case study is suggestive of a broader conclusion about the relationship between the scientific and the manifest image.
