It is widely recognized that Goodman's grue example demonstrates that the rules for induction, unlike those for deduction, cannot be purely syntactic. Ways in which Goodman's proof generalizes, however, are not widely recognized. Gruesome considerations demonstrate that neither theories of simplicity nor theories of empirical confirmation can be purely syntactic. Moreover, the grue paradox can be seen as an instance of a much more general phenomenon. All empirical investigations require semantic constraints, since purely structural constraints are inadequate. Both Russell's theory of empirical knowledge and Putnam's model-theoretic argument against metaphysical realism illustrate the inadequacy of purely structural constraints

Many liberal societies are deeply committed to freedom of speech. This commitment is so entrenched that when it seems to come into conflict with other commitments (e.g., gender equality), it is often argued that the commitment to speech must trump the other commitments. In this paper, we argue that a proper understanding of our commitment to free speech requires being clear about what should count as speech for these purposes. On the approach we defend, should get a special, technical sense, different from its ordinary sense. We offer a partial characterization of this technical sense. Finally, we argue that if certain theorists (e.g., MacKinnon) are right about what (some) pornography does, then it should fall outside the scope of the free-speech principle. If so, then contrary to first appearances, pornography may not be a case in which our commitments to freedom and gender equality come into conflict.

I here present two different models of oppressive speech. My interest is not in how speech can cause oppression, but in how speech can actually be an act of oppression. As we shall see, a particular type of speech act, the exercitive, enacts permissibility facts. Since oppressive speech enacts permissibility facts that oppress, speech must be exercitive in order for it to be an act of oppression. In what follows, I distinguish between two sorts of exercitive speech acts (the standard exercitive and the covert exercitive) and I argue that each such exercitive affords a distinct model of oppressive speech.
