This paper is an attempt at a vindication of induction. The point of departure is that induction requires a justification and that the only kind of justification possible is a vindication. However traditional vindications of induction have rested on unjustified assumptions about the aim of induction. This vindication takes the end pursued in induction simply to be correct prediction. It is argued that induction is the only reasonable way of pursuing this end because induction is the only objective method of (...) predicting. While objectivity is not a necessary condition for successful predicting, it is a sufficient condition for the possession of a property that is, in turn, a necessary condition for correct predicting; and further there could be no reason to expect any non-objective method to possess this necessary condition for success. Induction is the only objective method of predicting for it alone uses facts which must be identified by any predicting method based on rules; and it alone uses these facts according to a relationship that must hold between facts and any meaningful empirical statement. Any alternative to induction must assume that the factual regularities that have been detected will alter in the future and the way they are expected to alter must be arbitrary. It is further claimed that this vindication is proof against the criticisms that have been advanced against practicalist justifications of induction. (shrink)

J. J. Katz in “The Problem of Induction and its Solution” argues that not only a validation but also a vindication of induction is impossible. In the course of his argument a number of interesting issues arise about what is actually required for a satisfactory vindication. The aim of those who have sought to provide a vindication for induction has been to show that it is the most satisfactory means for forming expectations about the future; they have accepted the impossibility (...) of showing that induction must, or will probably, lead to true predictions. Feigl gives a general characterisation of vindication as an “argument concerning means with respect to ends” and contrasts it to validation which is a justification of a knowledge claim by establishing it as true or probably true. We cannot validate the rules of induction but we can give a vindication of the adoption of these rules. Katz accepts Feigl's distinction in general terms but proposes some modifications to meet certain defects which he believes to be present in the latter's account. Katz distinguishes two senses of vindication, an “expediency vindication” which “establishes a justificandum as a suitable means,” while a “preferability vindication” “establishes the justificandum as the preferable means for achieving the end.” An expediency vindication shows that the proposed means is a sufficient condition for achieving the end in view, but it need not establish this means as necessary to achieve this end. A preferability vindication will establish the means as necessary to achieve this end in the best way. He then proceeds as follows: “an argument which demonstrates that a justificandum is a necessary condition—but only a necessary condition—for achieving the relevant end is not a real vindication.” He holds that the vindication of a certain means must show at least that it will achieve the end sought, and preferably that it is the best way of achieving this end.

In this paper, I try to articulate and clarify the role of the epistemic authority of experts in Kuhn’s explanation for the transition process between rival paradigms in the scientific revolutionary period. If science progresses, that process should contribute to the attainment of the cognitive aim of science, namely, the articulation of paradigms increasingly successful at the resolution of problems. It is hard to see that process as rational and as attaining the cognitive aim of science without the consideration of (...) epistemic authority.The mistake of Kuhn was to emphasize and clarify insufficiently the role of the epistemic authority of experts; his critics failed for ignoring it altogether.
