Ralph Cudworth (1617–1688) is a member of the group of philosophers and theologians commonly called ‘the Cambridge Platonists’. Although not part of the canon of great early modern philosophers, Cudworth’s work is of more than merely passing interest. Cudworth was an influential philosopher in the early modern period both for his criticisms of contemporaries like Hobbes, Descartes, and Spinoza, and for his own distinctive philosophical views. This entry focusses on Cudworth’s views on mind and body, considering both his criticisms of contemporaries’ theories of mind and body, and outlining his alternative form of dualism in which plastic nature plays a central role

It is widely held by philosophers not only that there is a causal condition on perception but also that the causal condition is a conceptual truth about perception. One influential line of argument for this claim is based on intuitive responses to a style of thought experiment popularized by Grice. Given the significance of these thought experiments to the literature, it is important to see whether the folk in fact respond to these cases in the way that philosophers assume they should. We test folk intuitions regarding the causal theory of perception by asking our participants to what extent they agree that they would ‘see’ an object in various Gricean scenarios. We find that the intuitions of the folk do not strongly support the causal condition; they at most strongly support a ‘no blocker’ condition. We argue that this is problematic for the claim that the causal condition is a conceptual truth.

According to naïve realist (or primitivist) theories of colour, colours are sui generis mind-independent properties. The question that I consider in this paper is the relationship of naïve realism to what Mark Johnston calls Revelation, the thesis that the essential nature of colour is fully revealed in a standard visual experience. In the first part of the paper, I argue that if naïve realism is true, then Revelation is false. In the second part of the paper, I defend naïve realism against a number of objections

Inter-species variation in colour perception poses a serious problem for the view that colours are mind-independent properties. Given that colour perception varies so drastically across species, which species perceives colours as they really are? In this paper, I argue that all do. Specifically, I argue that members of different species perceive properties that are determinates of different, mutually compatible, determinables. This is an instance of a general selectionist strategy for dealing with cases of perceptual variation. According to selectionist views, objects simultaneously instantiate a plurality of colours, all of them genuinely mind-independent, and subjects select from amongst this plurality which colours they perceive. I contrast selectionist views with relationalist views that deny the mind-independence of colour, and consider some general objections to this strategy

What is the relationship between being coloured and looking coloured? According to Alva Noë, to be coloured is to manifest a pattern of apparent colours as the perceptual conditions vary. I argue that Noë’s ‘phenomenal objectivism’ faces similar objections to attempts by traditional dispositionalist theories of colour to account for being coloured in terms of looking coloured. Instead, I suggest that to be coloured is to look coloured in a ‘non-perspectival’ sense, where non-perspectival looks transcend specific perceptual conditions.
