Induction and deduction are foundational to human rationality because it is impossible for a human to stop using them. Indeed what it means to be humanly rational is that one uses these reasoning systems. There is no sense in trying to discover any justification for these two reasoning systems because even if we discovered that one of them ought not to be used, then we could not stop using them. If we cannot stop using them even if we ought to, then it is futile, indeed a waste of time, to examine if we ought not to use them.
