This chapter looks at David Hume's problem of induction and Reichenbach's pragmatic way of living with the problem of induction. This problem arises because it seems impossible to gain a non-circular justification for induction. A very different way of living with the problem of induction is offered by Hans Reichenbach. Reichenbach agrees with Hume that there is no justification for induction. The problem for the epistemic internalist is to explain how philosophers’ widespread induction-based beliefs are justified given that there are no noncircular grounds available in support of these beliefs. Reichenbach's idea is that induction is rational because if philosophers don't employ induction they are guaranteed to end up with very few true beliefs about the world, while if they do use induction then they at least have the chance to form lots of true beliefs about the world through their inductive inferences.
