The "Transcendental Deduction" in Kant's Critique of Pure Reason is one of the great mirrors of philosophy. By that I mean that there seems to be no steady and unchanging image to be found in that text; each philosopher who approaches it finds in it a reflection of his or her own deepest concerns. Jay Rosenberg's new book, "Accessing Kant: A Relaxed Introduction to the Critique of Pure Reason" is no exception. Rosenberg lays out a different approach to the central argument of the first Critique from those found in other commentaries. I want to bring out some of the central features of that approach, some of its history, and, finally, raise some questions about how closely his approach might come to Kant's own intentions.

I argue that John McDowell’s attempt to refute Wilfrid Sellars’s two-component analysis of perceptual experience and substitute for it a conception according to which perceptual experience is the “conceptual shaping of sensory consciousness” fails. McDowell does not recognize the subtle dialectic in Sellars’s thought between transcendental and empirical considerations in favor of a substantive conception of sense impressions, and McDowell’s own proposal seems to empty the notion of sensory consciousness of any real significance.

Sellars was committed to the irreducibility of the semantic, the intentional, and the normative. Nevertheless, he was also committed to naturalism, which is prima facie at odds with his other theses. This paper argues that Sellars maintained his naturalism by being linguistically pluralistic but ontologically monistic. There are irreducibly distinct forms of discourse, because there is an array of distinguishable functions that language and thought perform, but we are not ontologically committed to the array of apparently non-natural entities or relations mentioned in the metalanguage. However, there is an underlying relation between language and world presupposed by all empirically meaningful language. In his early work Sellars sought to describe this relation in linguistic terms as a form of 'pure description', but inadequacies in that notion drove him towards the naturalistic relation between language and world that he came to call 'picturing'

This paper investigates Sellars's complex attitude towards idealism. It distinguishes between the epistemologically-based arguments that led many empiricists to idealism and a different set of more purely metaphysical arguments that came to dominate in German Idealism. Sellars resolutely rejects all of the epistemological arguments for idealism, but shows much greater sympathy with the metaphysical arguments. It is then argued that Sellars introduced his notion of picturing to avoid falling into such an idealism.

Sellars claims completeness for both the “manifest” and the “scientific images” in a way that tempts one to assume that they are independent of each other, while, in fact, they must share at least one common element: the language of individual and community intentions. I argue that this significantly muddies the waters concerning his claim of ontological primacy for the scientific image, though not in favor of the ontological primacy of the manifest image. The lesson I draw is that we need to reassess the aims of ontology.

In the following dialogue between TT - a foundationalist - and WdeV - a Sellarsian, we offer our differing assessments of the principle for observational knowledge proposed in Wilfrid Sellars's 'Empiricism and the Philosophy of Mind'. Sellars writes: 'For a Konstatierung "This is green" to "express observational knowledge", not only must it be a symptom or sign of the presence of a green object in standard conditions, but the perceiver must know that tokens of "This is green" are symptoms of the presence of green objects in conditions which are standard for visual perception.' In the ensuing dialogue, TT argues that it sets the bar too high when knowledge about perceptual conditions is required for ordinary observational knowledge - that young children, for example, are implausibly excluded as knowers given Sellars's principle. WdeV defends Sellars's metaknowledge requirement against these charges. Results from developmental psychology are surveyed for what they show about the actual capabilities of young children. The implications of these results for the success of Sellars's principle are debated.

Robert B. Brandom’s From Empiricism to Expressivism ranges widely over fundamental issues in metaphysics, with occasional forays into epistemology as well. The centerpiece is what Brandom calls ‘the Kant-Sellars thesis about modality’. This is ‘[t]he claim that in being able to use ordinary empirical descriptive vocabulary, one already knows how to do everything that one needs to know how to do, in principle, to use alethic modal vocabulary – in particular subjunctive conditionals’. Despite claiming descent from Sellars, Brandom defends here a version of modal realism and tries hard to limit Sellarsian nominalism, all in the service of elaborating Brandom’s own version of pragmatism. The range of issues Brandom addresses defies adequate consideration in a critical notice, so I confine myself here to a single issue: What is..

The Metaphysics of Mind is metaphysics in the logical-reconstruction-of-language mode. Tye claims the assertions of ordinary folk psychology are frequently true and attacks the idea that there are any mental events, but he is not, on the whole, concerned with what kinds of theories are best able to handle the empirical evidence we have. Rather, Tye’s central focus is an argument that the ontological commitments of psychological discourse in general are very minimal: just “persons and other sentient creatures together with sets built up out of such entities”.
