Abstract

One widely recognized difference between laws and accidental generalizations lies in the ability of the former versus the inability of the latter to support certain sorts of related subjunctive conditionals. Nelson Goodman's theory of projectibility is here evaluated on the basis of its implications for the relative acceptability of conflicting subjunctive conditionals or counterfactuals. It is argued that the theory's extensionalistic character precludes its dealing adequately with cases of a certain type in which the difference between two counterfactuals, one acceptable and the other unacceptable, is clearly related to a difference in nomological status between their indicative counterparts.
