In his recent paper ‘Analyticity: An Unfinished Business in Possible-World Semantics’ (Rabinowicz 2006), Wlodek Rabinowicz takes on the task of providing a satisfactory definition of analyticity in the framework of possible-worlds semantics. As usual, what Wlodek proposes is technically well-motivated and very elegant. Moreover, his proposal does deliver an interesting analytic/synthetic distinction when applied to sentences with natural kind terms. However, the longer we thought and talked about it, the more questions we had, questions of both philosophical and technical nature. Hence the idea of this little paper – for how better to honor a philosopher than by trying very hard to criticize him? After quickly running over some background in possible worlds semantics and setting out Wlodek's proposal against that background, we shall bring up and discuss our questions in sections 3 – 5. In the final section, we shall also make a stab at a different solution to the problem, making use of our own earlier idea of relational modality.

Peter Pagin Is the principle of semantic compositionality compatible with the principle of semantic holism? The question is of interest, since both principles have a lot that speaks for them, and since they do seem to be in conflict. The view that natural languages have compositional structure is almost unavoidable, since linguistic communication by means of new combinations of words would be virtually incomprehensible otherwise. And holism too seems generally plausible, since the meaning of an expression is directly connected with the way that expression interacts with other.

In Michael Dummett’s manifestability challenge to truth conditional semantics, it is argued that the meaning of sentence cannot be its truth conditions, for then a speaker’s knowledge of the meaning would not in all cases be manifestable. In those cases, the speaker would not know how to find out whether the truth conditions are satisfied or not. By contrast, knowledge of what counts as a proof of a sentence would pass the manifestability test, since a speaker is supposed always to be capable of deciding whether or not a given object is a proof of a given sentence. There is a problem for the positive part, however, for there is no guarantee that a compositional proof-theoretic semantics in all cases provides knowledge sufficient for recognizing any proof of a provable sentence for which the meaning is given. In those cases, the speaker need not know how to find out whether a given object is a proof of the sentence. Hence, if knowledge of meaning is required to be manifestable, there is no guarantee in general is compositionally specifiable.

In earlier work (Glüer, K. and P. Pagin. 2006. Proper names and relational modality. Linguistics & Philosophy 29: 507–35; Glüer, K. and P. Pagin. 2008. Relational modality. Journal of Logic, Language and Information 17: 307–22), we developed a semantics for (metaphysical) modal operators that accommodates Kripkean intuitions about proper names in modal contexts even if names are not rigid designators. Graeme Forbes (2011. The problem of factives for sense theories. Analysis 71: 654–62.) criticizes our proposal. He argues that our semantics predicts readings for certain natural language sentences which these simply do not have. These sentences contain mixed contexts involving factive attitude verbs. We argue that the readings our semantics predicts do indeed exist, even if it might take a little work to bring them out. Moreover, denying their existence would have some rather unattractive consequences
