All three authors agree that 'This glass is brittle' entails 'If it were suitably struck, it would break'. They also agree that such a statement, if true, requires a state of affairs whose existence makes it true (its truthmaker). They disagree as to its nature. For Place, it is an intentional state which "points towards" a possibly-never-to-exist future and a counterfactual past. In accordance with the conceptualist theory of universals and the picture theory of meaning which he outlines, such states are construed as properties of particulars. They provide Hume's "invisible glue" which sticks cause to effect.

I argue the case for a rehabilitation of the "picture theory" of the meaning of sentences expounded by Wittgenstein (1921/1971) in the Tractatus, but abandoned by him in moving from his earlier to his later philosophy. This rehabilitation requires the replacement of 'facts' as the objects which sentences depict by 'situations' (Barwise and Perry 1983) and the recognition that the situation depicted by a sentence is an "intentional object" (Brentano 1871/1995). It also implies a different view of the way his sense (Sinn)/reference (Bedeutung) distinction should be applied to the meaning of sentences from that maintained by Frege (1892/1960) himself. Such a theory opens the door to a thorough-going empiricist theory of the acquisition of both concepts and sentence structure.
