Rae Langton and Jennifer Hornsby have argued that pornography might create a climate whereby a woman’s ability to refuse sex is literally silenced or removed. Their central argument is that a failure of ‘uptake’ of the woman’s intention means that the illocutionary speech act of refusal has not taken place. In this paper, I challenge the claims from the Austinian philosophy of language which feature in this argument. I argue that uptake is not in general required for illocution, nor is it required for refusal in particular. I conclude with remarks on the relationship between illocutionary and perlocutionary speech-acts.

In Bird 2001 I argued that a law that might seem to many to be contingent is in fact necessary. In short the argument is this. Given the existence of salt and water, Coulomb’s law of electrostatic attraction is sufficient to make the former dissolve in the latter. So any possible world in which salt failed to dissolve in water would be one in which Coulomb’s law is false. However, it is also the case that the existence of salt depends on Coulomb’s law. If Coulomb’s law is false then salt cannot exist. So there is no possible world in which salt exists and in which it does not dissolve in water.

In this paper I argue that it is not a priori that all the laws of nature are contingent. I assume that the fundamental laws are contingent and show that some non-trivial, a posteriori, non-basic laws may nonetheless be necessary in the sense of having no counterinstances in any possible world. I consider a law LS (such as 'salt dissolves in water') that concerns a substance S. Kripke's arguments concerning constitution show that the existence of S requires that a certain deeper level law or variants thereof hold. At the same time, that law and its variants may each entail the truth of LS. Thus the existence of S entails LS. Consequently there is no world in which S exists and fails to obey LS. I consider the conditions concerning the fundamental laws that would make this phenomenon ubiquitous. I conclude with some consequences for metaphysics.

Kuhn's incommensurability thesis seems to challenge scientific realism. One response to that challenge is to focus on the continuity of reference. The casual theory of reference in particular seems to offer the possibility of continuity of reference that woud provide a basis for the sort of comparability between theories that the realist requires. In "Dubbing and Redubbing: the vulnerability of rigid designation" Kuhn attacks the causal theory and the essentialism to which is is related. Kuhn's view is defended by Rupert Read and Wes Sharrock. In this paper I examine the arguments presented by Kaul, Read and Sharrock and show that they provide no reason to doubt either the causal theory or essentialism.
