On the basis of impossibility results on probability, belief revision, and conditionals, it is argued that conditional beliefs differ from beliefs in conditionals qua mental states. Once this is established, it will be pointed out in what sense conditional beliefs are still conditional, even though they may lack conditional contents, and why it is permissible to still regard them as beliefs, although they are not beliefs in conditionals. Along the way, the main logical, dispositional, representational, and normative properties of conditional beliefs are studied, and it is explained how the failure of not distinguishing conditional beliefs from beliefs in conditionals can lead philosophical and empirical theories astray.

In this paper we address a long standing issue concerning imperative subjects: What explains their semantic association with the addressee? We do so by working at the intersection of syntax and semantics and by taking into account data from two other clause types, exhortatives and promissives. These types are minimally different from imperatives and yet have not been examined in the same light. We will show that, by adding these missing pieces to the puzzle, we obtain a clearer picture of the syntax and semantics of this class of clauses, labelled JUSSIVES. We claim that the jussives update the conversational context in the same way, differing only in a single parameter, namely which conversational participant they relate to. Syntax plays a crucial role in the identification of this participant.

This paper argues that ‘that’-clauses are not singular terms (without denying that their semantical values are propositions). In its first part, three arguments are presented to support the thesis, two of which are defended against recent criticism. The two good arguments are based on the observation that substitution of ‘the proposition that p’ for ‘that p’ may result in ungrammaticality. The second part of the paper is devoted to a refutation of the main argument for the claim that ‘that’-clauses are singular terms, namely that this claim is needed in order to account for the possibility of quantification into ‘that’-clause position. It is shown that not all quantification in natural languages is quantification into the position of singular terms, but that there is also so-called ‘non-nominal quantification’. A formal analysis of non-nominal quantification is given, and it is argued that quantification into ‘that’-clause position can be treated as another kind non-nominal quantification.

In (1), the talking event described in the matrix clause is elaborated on in the following adjunct: the arguing about the data and the theories makes up the content of the talking referred to in the matrix clause. In (2), on the other hand, the events (or sub-events of a single complex event) described are in a causeconsequence relation, a result of the action described in the matrix clause being that the porcelain vase breaks. These two examples illustrate a central issue for the interpretation of -ing adjuncts: the relation holding between the event described in the adjunct and the event described in the matrix clause is not always the same – in fact, as we’ll see, there is quite a range of possibilities. So the question is: how is the particular relation arrived at?

Conditionals are central to inference. Before people can draw inferences about a natural language conditional, they must interpret its meaning. We investigated interpretation of uncertain conditionals using a probabilistic truth table task, focussing on (i) conditional event, (ii) material conditional, and (iii) conjunction interpretations. The order of object (shape) and feature (color) in each conditional’s antecedent and consequent was varied between participants. The conditional event was the dominant interpretation, followed by conjunction, and took longer to process than conjunction (mean difference 500 ms). Material conditional responses were rare. The proportion of conditional event responses increased from around 40% at the beginning of the task to nearly 80% at the end, with 55% of participants showing a qualitative shift of interpretation. Shifts to the conditional event occurred later in the feature-object order than in the object-feature order. We discuss the results in terms of insight and suggest implications for theories of interpretation.

It has been argued that Psychological Externalism is irrelevant to psychology. The grounds for this are that PE fails to individuate intentional states in accord with causal power, and that psychology is primarily interested in the causal roles of psychological states. It is also claimed that one can individuate psychological states via their syntactic structure in some internal "language of thought". This syntactic structure is an internal feature of psychological states and thus provides a key to their causal powers. I argue that in fact any syntactic structure deserving the name will require an external individuation no less than the semantic features of psychological states.

This essay continues my investigation of `syntactic semantics': the theory that, pace Searle's Chinese-Room Argument, syntax does suffice for semantics (in particular, for the semantics needed for a computational cognitive theory of natural-language understanding). Here, I argue that syntactic semantics (which is internal and first-person) is what has been called a conceptual-role semantics: The meaning of any expression is the role that it plays in the complete system of expressions. Such a `narrow', conceptual-role semantics is the appropriate sort of semantics to account (from an `internal', or first-person perspective) for how a cognitive agent understands language. Some have argued for the primacy of external, or `wide', semantics, while others have argued for a two-factor analysis. But, although two factors can be specified–-one internal and first-person, the other only specifiable in an external, third-person way–-only the internal, first-person one is needed for understanding how someone understands. A truth-conditional semantics can still be provided, but only from a third-person perspective.

When philosophers and linguists theorize about the nature of conditionals, they tend to make a number of assumptions about the linguistic structure of these sentences. For example, they almost invariably assume that conditionals have “antecedents” and “consequents” and that these have the structure of independent clauses. With a few exceptions, they assume that conditionals are categorized according to whether they are in the “indicative” or the “subjunctive” “mood”. However, rarely do they formulate criteria for identifying these moods, or for distinguishing between indicative and subjunctive conditionals.Through an analysis of the coordinated verb tense structures of the clauses of English conditionals, I challenge these and other related assumptions and show that the one relatively well-developed attempt to provide criteria for distinguishing between indicative and subjunctive conditionals---that of Gibbard (1980)---fails in its task. I then offer an alternative account of the linguistic structure of conditional constructions. To represent their structure I use first-order predicate logic with added devices to indicate deictic and anaphoric reference.
