Abstract: Induction has given way to Infere nce to the Best Explanation (IBE) in the epistemology hospitable to realism, or to metaphysics in general. Both Dretske and Armstrong provide severe critiques of traditional notions of Induction, and offer new foundations for inductive methods. This chapter and the next argue that neither Induction nor IBE qualifies as a rational strategy for change of opinion.
