Some philosophers of mind have argued for considering consciousness as a further fundamental feature of reality in addition to its physical properties. Hence most of them are property dualists. But some of them are panpsychists. In the present paper it will be argued that being a real property dualist essentially entails being a panpsychist. Even if panpsychism deals rather elegantly with certain problems of the puzzle of consciousness, there’s no way around the composition problem. Adhering to the fundamentality claim of the mind, it will be shown that only a radical revision of metaphysics will allow the panpsychist to avoid these troubles, and hence that a panpsychist must adopt Leibnizian idealism

Frank Jackson argued, in an astronomically frequently cited paper on 'Epiphenomenal qualia '[Jackson 1982 that materialism must be mistaken. His argument is called the knowledge argument. Over the years since he published that paper, he gradually came to the conviction that the conclusion of the knowledge argument must be mistaken. Yet he long remained totally unconvinced by any of the very numerous published attempts to explain where his knowledge argument had gone astray. Eventually, Jackson did publish a diagnosis of the reasons why, he now thinks, his knowledge argument against materialism fails to prove the falsity of materialism [Jackson 2005. He argues that you can block the knowledge argument against materialism - but only if you tie yourself to a dubious doctrine called representationalism. We argue that the knowledge argument fails as a refutation of either representational or nonrepresentational materialism. It does, however, furnish both materialists and dualists with a successful argument for the existence of distinctively first-person modes of acquaintance with mental states. Jackson's argument does not refute materialism: but it does bring to the surface significant features of thought and experience, which many dualists have sensed, and most materialists have missed.

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this paper is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness.

John Locke’s foundational place in the history of British empiricism and liberal political thought is well established. So, in what sense can Locke be considered a modern European philosopher? Identity and Difference argues for reassessing this canonical figure. Closely examining the "treatise on identity" added to the second edition of An Essay Concerning Human Understanding, Étienne Balibar demonstrates Locke’s role in the formation of two concepts central to the metaphysics of the subject—consciousness and the self—and the complex philosophical, legal, moral and political nature of his terms. With an accompanying essay by Stella Sandford, situating Balibar’s reading of Locke in the history of the reception of the Essay and within Balibar’s other writings on "the subject," Identity and Difference rethinks a crucial moment in the history of Western philosophy.

Although the index is one of the best known features of Peirce's theory of signs there is little appreciation of Peirce's theory of the index amongst contemporary philosophers of language. Amongst Peirce scholars, the value placed on Peirce's account is greater, but is largely based on Thomas Goudge's paper, "Peirce's Index" (Goudge, 1965). Despite marking a crucial milestone in our comprehension of Peirce's theory, our understanding of indices and indexical reference has grown markedly over the last forty years. Time has now come, then, to develop the work that Goudge began and to provide a full analysis of Peirce's account that makes its value to the philosophy of language clear. I undertake this enterprise here.

In this short text, a distinguished philosopher turns his attention to one of the oldest and most fundamental philosophical problems of all: How it is that we are able to sort and classify different things as being of the same natural class? Professor Armstrong carefully sets out six major theories—ancient, modern, and contemporary—and assesses the strengths and weaknesses of each. Recognizing that there are no final victories or defeats in metaphysics, Armstrong nonetheless defends a traditional account of universals as the most satisfactory theory we have.This study is written for advanced students, but as Armstrong goes considerably beyond his earlier work on this topic, it will interest professional scholars as well. Carefully plotted and clearly written, Universals is both a paradigm of exposition and a case study on the value of careful analysis of fundamental issues in philosophy

I develop an account of scientific representations building on Charles S. Peirce's rich, and still underexplored, notion of iconicity. Iconic representations occupy a central place in Peirce's philosophy, in his innovative approach to logic and in his practice as a scientist. Starting from a discussion of Peirce's approach to diagrams, I claim that Peirce's own representations are in line with his formulation of iconicity, and that they are more broadly connected to the pragmatist philosophy he developed in parallel with his scientific work. I then defend the contemporary relevance of Peirce's approach to iconic representations, and specifically argue that Peirce offers a useful ‘third way’ between what Mauricio Suárez has recently described as the ‘analytical’ and ‘practical’ inquiries into the concept of representation. As a philosophically minded scientist and an experimentally inclined philosopher, Peirce never divorced the practice of representing from questions about what counts as a representation...

A Naive Realist Theory of Colour defends the view that colours are mind-independent properties of things in the environment, that are distinct from properties identified by the physical sciences. This view stands in contrast to the long-standing and wide-spread view amongst philosophers and scientists that colours don't really exist - or at any rate, that if they do exist, then they are radically different from the way that they appear. It is argued that a naive realist theory of colour best explains how colours appear to perceiving subjects, and that this view is not undermined either by reflecting on variations in colour perception between perceivers and across perceptual conditions, or by our modern scientific understanding of the world. A Naive Realist Theory of Colour also illustrates how our understanding of what colours are has far-reaching implications for wider questions about the nature of perceptual experience, the relationship between mind and world, the problem of consciousness, the apparent tension between common sense and scientific representations of the world, and even the very nature and possibility of philosophical inquiry.

It is difficult to find agreement on what constitutes perceiving.at Rovereto, Italy. The term is used in a wide array of domains ranging from psychology to physiology to aesthetics, and over time it has also acquired diverse connotations within various disciplines. Current perceptual science, however, even when it deals with qualitative aspects of experience, for example phenomena of lightness and colour, almost exclusively explains them in terms of primary qualities or stimuli quantitatively understood. The fact that science treats qualitative experiences in terms of stimuli is important, because almost nothing of phenomenal perception as such is quantitative in nature. The paper argues for a qualitative science of perceiving, its methodology, its laws, and its possible developments
