A Peircean Approach to Programs for Routine Expansion of Belief.

This paper engages with Isaac Levi's approach to justifying changes in our states of full belief and offers a Peircean criticism of his strategy for resolving conflicts between the results of what inquirers deem to be the most reliable programs for a given situation and the settled beliefs about which we have no doubts. In the first section, I discuss the central features of Levi's theory of justifying changes to our state of full belief. In the second section, I present a Peircean approach to evaluating the reliability of these programs for routine expansion of belief, and I argue that there is a conflict between Levi's approach to situations where an inquirer has expanded her beliefs into inconsistency and Peirce's criticisms of non-scientific methods for settling opinion. The third section presents two potential objections to the Peircean approach, objections that emphasize the importance of our concern to avoid error, and in the fourth section, I propose an original supplement to the Peircean approach that better addresses that concern. Ultimately, my aim is to develop and defend a Peircean approach that is in opposition to Levi's views about when it is appropriate to question the reliability of our programs for routine expansion of belief but that also addresses his legitimate worries about underemphasizing our concern to avoid error.
