This paper discusses the semantic theory presented in Robert Brandom’s Making It Explicit . I argue that it is best understood as a special version of dynamic semantics, so that these semantics by themselves offer an interesting theoretical alternative to more standard truth-conditional theories. This reorientation also has implications for more foundational issues. I argue that it gives us the resources for a renewed argument for the normativity of meaning. The paper ends by critically assessing the view in both its development and motivations.

This paper discusses free-choice like effects in generics. Just as Jane may drink coffee or tea can be used to convey Jane may drink coffee and Jane may drink tea (she is “free to choose”), some generics with disjunctive predicates can be used to convey conjunctions of simpler generics: elephants live in Africa or Asia can be used to convey elephants live in Africa and elephants live in Asia. Investigating these logically slightly more complex generics and especially the free-choice like effects throws light on both the semantics of generics and the interaction between world knowledge and the interpretive options generics offer. This paper presents a package of semantic and pragmatic hypotheses to account for the data, including why the effect is absent in the superficially logically similar elephants live in Africa or give birth to live young.

This paper investigates the interaction between semantic theories for cp-laws (roughly, laws that hold “all things equal”) and metaphysical theories of kinds in the special sciences. Its central conclusion is that cp-laws concerning kinds behave differently from cp-laws concerning non-kinds: “ravens are black” which concerns the kind corvus corax, behaves differently from from “albino ravens are white” which concerns the non-kind grouping of albino ravens. I argue that this difference is in the first instance logical: the two sorts of cp-laws give rise to different inferential patterns. I draw two further conclusions. The difference in logical behavior poses a severe problem for extant semantic theories of cp-laws, and: we cannot elucidate the distinction between kinds and non-kinds by suggesting that only kinds can appear in laws.

Theories of explanation seek to tell us what distinctively explanatory information is. The most ambitious ones, such as the DN-account, seek to tell us what an explanation is, tout court. Less ambitious ones, such as causal theories, restrict themselves to a particular domain of inquiry. The least ambitious theories constitute outright skepticism, holding that there is no reasonably unified phenomenon to give an account of. On these views, it is impossible to give any theories of explanation at all. I argue that both the less ambitious and outright skeptical varieties are committed to a certain context-sensitivity of our explanatory discourse. And though this discourse is almost certainly context-sensitive in some respects, it does not exhibit the context-sensitivity less than fully ambitious theories are committed to. Therefore, all accounts that seek to restrict themselves in scope, including causal accounts of explanation, fail.

I contrast two approaches to the interpretation of generics such as ‘ravens are black:’ majority-based views, on which they are about what is the case most of the time, and inquiry-based views, on which they are about a feature we focus on in inquiry. I argue that majority-based views face far more systematic counterexamples than has previously been supposed. They cannot account for generics about kinds with multiple characteristic properties, such as ‘elephants live in Africa and Asia.’ I then go on to sketch an inquiry-based view.

Intentionalism is the claim that the phenomenological properties of a perceptual experience supervene on its intentional properties. The paper presents a counterexample to this claim, one that concerns visual grouping phenomenology. I argue that this example is superior to superficially similar examples involving grouping phenomenology offered by Peacocke (1983), because the standard intentionalist responses to Peacocke’s examples cannot be extended to mine. If Intentionalism fails, it is impossible to reduce the phenomenology of an experience to its content.

The paper discusses comparative generic sentences As are F-er than Bs—girls do better than boys in grade school, for example—which pose severe problems for extant accounts. In their stead, the paper proposes reconceiving the LF of generic sentences as more closely akin to that of sentences containing non-generic plurals, paradigmatically plural definite descriptions. Given this one crucial change, several otherwise puzzling features of comparative generics are immediately explicable, including their relatively weak truth conditions and some of the logical relations they enter into.

Ceteris Paribus (cp-)laws may be said to hold only “other things equal,” signaling that their truth is compatible with a range of exceptions. This paper provides a new semantic account for some of the sentences used to state cp-laws. Its core approach is to relate these laws to natural language on the one hand — by arguing that cp-laws are most naturally expressed with generics — and to natural kinds on the other — by arguing that the semantics of generics in the context of the special sciences are best spelled out by appeal to natural kinds. The paper then goes on to draw on these semantics in order to illuminate several problems raised by cp-laws, some familiar, some new.
