In Mind and World McDowell describes Gareth Evans’s ‘master thought’ as follows:
Frege’s notion of sense, which Frege introduces in terms of modes of presentation, can accommodate the sorts of connection between thinkers and particular objects that have been recognized to make trouble for the generalized Theory of Descriptions. 106.
A consequence of this ‘master thought,’ as McDowell reads Evans, is that ‘the right gloss on “conceptual” is not “predicative” but “belonging to the realm of Fregean sense”.’ I agree that this point is extremely important. In the appendix to Mind and World, McDowell offers clarification that draws out the importance I see in the implications of Evans’s ‘master thought’. McDowell there argues that ‘The realm of sense (Sinn) contains thoughts in the sense of what can be thought (thinkables) as opposed to acts or episodes of thinking.’ Up to this point the Fregean theory of sense is much in line with Husserl’s theory of the noema. The noema as Husserl understands it, including the perceptual noema as I argue in The Problem of Difference, is not to be confused with ‘acts or episodes of thinking,’ including perceptual acts, nor is it to be confused with the objects that are thought about, the objects that consciousness is consciousness of to stick with the Husserlian way of putting it. Deleuze himself will stress this Husserlian theory of sense, noting how the noema is neutral with respect to subjective acts on the one hand and states of affairs in the world on the other; moreover, as Deleuze will go on to point out, it is precisely the noema that makes possible the relationship between subjective acts and the world, it is what puts them into relationship with one another, or as Deleuze will also put it: it is the relationship that is external to the terms. Graham Harman has rightly stressed this aspect of Husserl’s thought, and in his hands he extends Husserl’s understanding of the noema as a noematic correlate or object in order to explain how withdrawn objects can come into communication with one another – they do so by way of another object, e.g., the noema. McDowell’s reading of Evans’s ‘master thought’ is much in line with this Husserlian point; however, as McDowell goes on the problematic reading of Frege occurs when sense is taken to be an object, and here McDowell would break sharply from the Husserlian account, as does Deleuze for whom sense is not an object but an event (more on this below). For McDowell ‘objects belong in the realm of reference (Bedeutung), not the realm of sense,’ for it is only in the realm of sense where, on McDowell’s Fregean view, ‘thought and reality meet.’
