Paul Boghossian has pointed out a ’circularity problem’ for dispositionalist theories of meaning: as a result of the holistic character of belief fixation, one cannot identify someone’s meaning such and such with facts of the form S is disposed to utter P under conditions C, without C involving the semantic and intentional notions that such a theory was to explain. Alex Miller has recently suggested an ’ultra‐sophisticated dispositionalism’ (modelled on David Lewis’s well known version of functionlism) and has argued that this version of dispositionalism escapes Boghossian’s ’circularity problem’. Miller argues, nonetheless, that another of Boghossian’s criticisms of dispositionalism, ’the infinity problem’ still applies to this ’ultra‐sophisticated dispositionalism’: C will still draw upon a potential infinity of mediating background clusters of belief. The present paper argues that the feature that ’the infinity problem’ presents as problematic is a feature of a host of familiar explanations. Our fundamental difficulty in this area is not our inability to understand how a more general model can be applied to a particular domain (the intentional understood as dispositional) but our failure to understand that general model itself (dispositional explanation).

The paper presents an interpretation of the thinking behind the early Wittgenstein's "general form of the proposition." It argues that a central role is played by the assumption that all domains of discourse are governed by the same laws of logic. The interpretation is presented partly through a comparison with ideas presented recently by Michael Potter and Peter Sullivan; the paper argues that the above assumption explains more of the key characteristics of the "general form of the proposition" than Potter and Sullivan suppose, including, in particular, its claim that the bases from which all other propositions are derived must be elementary propositions.
