 Mill rightly notes that upon observing that x1, x2, x3, … xn are P, human beings are disposed to form the belief that some relevantly similar xn+1 is P. Upon seeing ten swans, all white, for instance, we tend to believe that an eleventh unseen swan is also white. But, Mill holds, such inferences are not something we are merely disposed to believe, but something we have reason to believe—inferences of this general form are warranted. The question arises, of course, how it is that we can be warranted in believing the results of induction prior to their confirmation or disconfirmation—how it comes to be that we can be justified in believing an inductively suggested conclusion.
