Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is necessarily involved in the (...) perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding.

One crucial premise in the argument from illusion is the Phenomenal Principle. It states that if there sensibly appears to be something that possesses a sensible quality, then there is something of which the subject is aware that has that sensible quality. The principle thus enables the inference from a mere appearance to an existence (usually a mental one). In the argument from appearance, a similar move is taken by some philosophers—they infer a content from a mere appearance. There are (...) two kinds of defences for the Phenomenal Principle in the literature, namely, the epistemological one (e.g. H.H. Price) and the semantic one (e.g. Frank Jackson). I argue that neither consolidates the Phenomenal Principle. I particularly demonstrate that the appearance verb in premise 1 of the argument from illusion is not used in the phenomenal sense as it is used in the Phenomenal Principle, which renders the argument essentially invalid. To avoid invalidity, the proponents either give up the phenomenal use, which makes the argument unable to serve its original purpose, i.e. inferring an unusual existence, or they insist on the phenomenal use in all premises of the argument, which will trivialise the argument. I also demonstrate that a similar objection applies to the argument from appearance. (shrink)

I interpret the anti-idealist manoeuverings of the second half of Moore's 'The refutation of idealism', material as widely cited for its discussion of 'transparency' and 'diaphanousness' as it is deeply obscure. The centerpiece of these manoeuverings is a phenomenological argument for a relational view of perceptual phenomenal character, on which, roughly, 'that which makes the sensation of blue a mental fact' is a non-intentional relation of conscious awareness, a view close to the opposite of the most characteristic contemporary view going (...) under the transparency rubric. The discussion of transparency and diaphanousness is a sidelight, its principal purpose to shore up the main line of argumentation against criticism; in those passages all Moore argues is that the relation of conscious awareness is not transparent, while acknowledging that it can seem to be.

The term ‘realism’ and its contrasting terms have various related senses, although often they occlude as much as they illuminate, especially if ontological and epistemological issues and their tenable combinations are insufficiently clarified. For example, in 1807 the infamous ‘idealist’ Hegel argued cogently that any tenable philosophical theory of knowledge must take the natural and social sciences into very close consideration, which he himself did. Here I argue that Hegel ably and insightfully defends Newton’s causal realism about gravitational force, in (...) part by exposing a fatal equivocation in the traditional concept of substance, by criticizing some still-standard empiricist misconceptions of force, by emphasizing the role of explanatory integration in Newtonian mechanics, and by using his powerful semantics of singular, specifically cognitive reference to justify fallibilism regarding empirical justification, together with the semantic core of Newton’s Rule Four of (experimental) Philosophy—in a way that highlights a key fallacy in many arguments against realism, both in epistemology and within philosophy of science.

In current histories, C.I. Lewis is credited for bringing the strict concept of qualia – concerned solely with sensory states – into contemporary philosophy. It is this strict notion which is then credited with bringing in worries about inverted spectra, philosophical zombies, and the idea that we can individuate the senses introspectively. In this paper, I argue that this is a mistaken reading of Lewis and the history of qualia. I argue that the strict notion of qualia stems from the (...) work of Johannes Müller in the mid-nineteenth century and his work on individuating the senses. The structuralist psychologists who followed in his wake, in turn, developed an account where the qualitative character of experience played no causal role. I also show that Lewis adamantly rejects this strict concept of qualia. He instead endorses a pragmatic conception of qualia derived from William James in which evaluative states – such as the painfulness of pain – play an essential, causal role in the life of the organism. The upshot is that Lewis positions himself against the strict conception of qualia, arguing it is phenomenologically false and philosophically wrong-headed. (shrink)
