Frank Jackson's criticisms have helped me recognize some of the weaknesses in my proposed vindication of induction. The core of the argument I offered was that induction is the only method of predicting which is based in a nonarbitrary way on the facts. I still believe that this is so and that because of this property induction is the only reasonable way of predicting. However I now recognize defects in the argument by which I attempted to establish that the uniqueness of this property to induction constitutes its justification.
