Abstract

Inductive logics purport to specify, for any given hypothesis and any given evidence statement, whether and, if so, to what extent the evidence statement should bear on our confidence that the hypothesis is true. If we agree that there can only be one true answer to questions of this sort, then the project of inductive logic faces a serious difficulty, namely that the many different systems that have been proposed in the literature rarely reach an unanimous verdict. In this paper I investigate the possibility of settling empirically the question which of all the extant inductive logics is the correct one, or, if the correct inductive logic should still await formulation, which of the extant inductive logics is the least incorrect. My main point will be that the fact that empirical investigation of inductive logics necessarily requires the use of some inductive logic at the metalevel does not render the whole project futile. I also discuss and eventually dismiss some well-known Bayesian arguments to the effect that the debate about the correct inductive logic can be settled on a priori grounds and has in fact been settled in favour of Bayesianism
