Extract

The nature of analogies, and their legitimacy in argumentation and inference, is a disputed subject. This essay is intended to shed some light on the tangle of issues that it involves. After discussing in section one the different functions of analogy, in particular in explanation and in science, we present in section two a prima facie defense of analogical argument against those who repudiate it entirely and in section three an account of its logical structure. Section four argues that analogical inference does not collapse, as some of its critics contend, into standard induction, and section five attempts to explicate more precisely the warrant for analogical inference. We conclude in section six by suggesting a typology for arguments from analogy.

O., The Web of Belief (2nd ed.; New York: Random House, 1978), 9091.Google Scholar On Quine's view both induction and analogy produce hypotheses which still need to be evaluated and confirmed, but this does not entail that such inferences carry no epistemic warrant in and of themselves. The nature and extent of that warrant in the case of analogical inference is the subject of this paper. Accordingly, Herbert Feigl (“Other Minds and the Egocentric Predicament”, Journal of Philosophy, November 6, 1958, 979) is mistaken to denigrate analogical arguments for whose conclusions direct evidence is not available. (These are precisely the interesting and important cases.) On the one hand, if the conclusion has been directly established, one hardly needs an analogy. On the other hand, prior to its conclusion being checked, the argument is no stronger as an analogical inference than, ceteris paribiis. one whose conclusion cannot be directly confirmed (or disconfirmed).
