One of the more interesting philosophical debates in the seventeenth century concerned the nature and explanation of qualities. In order to understand these debates, it is important to place them in their proper historical-philosophical context. This book chapter starts with theoretical background in the work of Aristotle and the atomists, and then moves on to survey various theories of motion and rest, light, color, and sound, as well as the distinction between primary and secondary qualities, as represented in the work (...) of such figures as Berkeley, Boyle, Charleton, Cordemoy, Descartes, Desgabets, Galileo, Gassendi, Hobbes, Locke, Malebranche, Newton, Régis, Rohault, and Sennert.

In 1995, in my book, Ten Problems of Consciousness, I proposed a version of the theory of phenomenal consciousness now known as representationalism. The present book, in part, consists of a further development of that theory along with replies to common objections. It is also concerned with two prominent challenges for any reductive theory of consciousness: the explanatory gap and the knowledge argument. In addition, it connects representationalism with two more general issues: the nature of color and the location of (...) the phylogenetic dividing line between those creatures that are phenomenally conscious and those that are not.

I argue that any account of perceptual experience should satisfy the following two desiderata. First, it should account for the particularity of perceptual experience, that is, it should account for the mind-independent object of an experience making a difference to individuating the experience. Second, it should explain the possibility that perceptual relations to distinct environments could yield subjectively indistinguishable experiences. Relational views of perceptual experience can easily satisfy the first but not the second desideratum. Representational views can easily satisfy the (...) second but not the first desideratum. I argue that to satisfy both desiderata perceptual experience is best conceived of as fundamentally both relational and representational. I develop a view of perceptual experience that synthesizes the virtues of relationalism and representationalism, by arguing that perceptual content is constituted by potentially gappy de re modes of presentation.

In her first book, Marleen Rozemond explicates Descartes's aim to provide a metaphysics that would accommodate mechanistic science and supplant scholasticism.

I argue that Descartes treated the action of body on mind differently from the action of mind on body, as was common in the period. Descartes explicitly denied that there is a problem for interaction but his descriptions of interaction seem to suggest that he thought there was a problem. I argue that these descriptions are motivated by a different issue, the seemingly arbitrary connections between particular physical states and the particular mental states they produce. Within scholasticism there was already (...) a (yet different) problem concerning action of body on mind. I offer a comparison between Descartes and the scholastics. (shrink)

Recent exciting work on Cavendish’s natural philosophy highlights the important role of motion in her system. But what is motion, according to Cavendish? I argue that motion, for Cavendish, is what I call ‘compositional motion’: for a body to be in motion is just for it to divide from some matter and join with other matter. So when Cavendish claims to reduce all natural change to motion, she is really reducing all natural change to mereological change. Cavendish also uses ‘motion’ (...) to name the power that matter has to set itself in compositional motion. That power is not reducible to local motion. If motion is not local motion and if motive power is not a function of actual motion, then despite her polemics, Cavendish does not reduce natural change to local motion. Instead, she offers a unique and exciting account of natural change. (shrink)

The empress of Margaret Cavendish’s The Blazing World dismisses pure mathematicians as a waste of her time, and declares of the applied mathematicians that “there [is] neither Truth nor Justice in their Profession”. In Cavendish’s theoretical work, she defends the Empress’ judgments. In this paper, I discuss Cavendish’s arguments against pure and applied mathematics. In Sect. 3, I develop an interpretation of some relevant parts of Cavendish’s metaphysics and epistemology, focusing on her anti-abstractionism and what I call her ’assimilation’ view (...) of knowledge. In Sects. 4 and 5, I use this to develop Cavendish’s critiques of pure and applied mathematics, respectively. These critiques center on the claims that mathematics purports to describe non-beings, that nature is infinitely and irreducibly complex, and, perhaps most originally, that mathematical thinking deforms the subject of representation, not just the object.

This paper provides a systematic reconstruction of Cavendish's general epistemology and a characterization of the fundamental role of that theory in her natural philosophy. After reviewing the outlines of her natural philosophy, I describe her treatment of 'exterior knowledge', i.e. of perception in general and of sense perception in particular. I then describe her treatment of 'interior knowledge', i.e. of self-knowledge and 'conception'. I conclude by drawing out some implications of this reconstruction for our developing understanding of Cavendish's natural philosophy.

It is a live possibility that certain of our experiences reliably misrepresent the world around us. I argue that tracking theories of mental representation have difficulty allowing for this possibility, and that this is a major consideration against them.

My aim … is to show that the celestial machine is likened not to a kind of divine living being but rather to a clockwork. I consider the human body to be a machine … Although it may exaggerate to say that Descartes fathered the mechanization of biology, it is true that his Treatise of Man provided the first systematic development of the idea that a complete understanding of all the phenomena of life, including all abilities and behaviour of animals, (...) can be achieved by viewing living things as machines. To make this out, Decartes had to learn to think about living things in a new way. My first aim here is to identify the fundamental conceptual innovations at work in Descartes’ attempt to extend the new mechanics to include biology. My second aim is to locate the point at which Descartes’ mechanical imagination runs out. This requires study of Descartes’ scientific work on sense. (shrink)

The notion of representation figures centrally both in Descartes’ scientific theorizing about sense in humans and in his conceptual speculations about the nature of human cognition.Descartes’ philosophical innovation in the Dioptrics is the claim that sensing in humans is a kind of representing rather than a kind of resembling. This provides the cornerstone for his attack on traditional theories of sense, and it underwrites his own position that sensing is a kind of thinking, ascribable to the rational soul rather than (...) to any Aristotelean sensitive soul.

Commentators have argued that along with adopting a mechanical view of nature, Descartes developed two innovative views concerning sensation: sensation occurs without the involvement of an entity resembling the sensation, and sensations represent features of objects but without resembling them. When Descartes is interpreted as making both of these claims, it appears that in removing resemblance from the causal process of sensation, Descartes preserves the notion that sensations represent features of objects and that he does this by introducing a new (...) conception of representation — one not requiring resemblance.It is important to recognize that the two claims are distinct. The first claim, that the physical process of sensation does not involve something resembling the qualitative content of the sensation, does not in and of itself entail anything about the representational nature of the sensation. Or rather, what it does entail is that if sensations do represent their causes in objects, then it cannot be by presenting those causes to the mind as they exist in objects. (shrink)

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)

We argue that relationalism entails an unacceptable claim about the content of visual experience: that ordinary ‘red’ objects look like they look like they look like they’re red, etc.

According to Margaret Cavendish the entire natural world is essentially rational such that everything thinks in some way or another. In this paper, I examine why Cavendish would believe that the natural world is ubiquitously rational, arguing against the usual account, which holds that she does so in order to account for the orderly production of very complex phenomena (e.g. living beings) given the limits of the mechanical philosophy. Rather, I argue, she attributes ubiquitous rationality to the natural world in (...) order to ground a theory of the ubiquitous freedom of nature, which in turn accounts for both the world's orderly and disorderly behavior.

Are colors relational or non-relational properties of their bearers? Is red a property that is instantiated by all and only the objects with a certain intrinsic (/non-relational) nature? Or does an object with a particular intrinsic (/non-relational) nature count as red only in virtue of standing in certain relations - for example, only when it looks a certain way to a certain perceiver, or only in certain circumstances of observation? In this paper I shall argue for the view that color (...) properties are relational (henceforth, relationalism), and against the view that colors are not relational (henceforth, anti- or non-relationalism).

The target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically types of reflectance. This is probably a minority opinion, at least among color scientists. Textbooks frequently claim that physical objects are not colored, and that the colors are "subjective" or "in (...) the mind." The article has two other purposes: first, to introduce an interdisciplinary audience to some distinctively philosophical tools that are useful in tackling the problem of color realism and, second, to clarify the various positions and central arguments in the debate.

Scholarly interest in Margaret Cavendish's philosophical views has steadily increased over the past decade, but her epistemology has received little attention, and no consensus has emerged; Cavendish has been characterized as a skeptic, as a rationalist, as presenting an alternative epistemology to both rationalism and empiricism, and even as presenting no clear theory of knowledge at all. This paper concludes that Cavendish was only a modest skeptic, for she believed that humans can achieve knowledge through sensitive and rational perception as (...) well as through self-knowledge and can form probable opinions through reasoning.

The dispute between realists about color and anti-realists is actually a dispute about the nature of color properties. The disputants do not disagree over what material objects are like. Rather, they disagree over whether any of the uncontroversial facts about material objects--their powers to cause visual experiences, their dispositions to reflect incident light, their atomic makeup, and so on--amount to their having colors. The disagreement is thus about which properties colors are and, in particular, whether colors are any of the (...) properties in a particular set that is acknowledged on both sides to exhaust the properties of material objects. In a previous paper we discussed at length one attempt to identify colors with particular properties of material objects--namely, with their dispositions to cause visual experiences. Here we shall discuss a different and perhaps more influential version of realism, which says that the colors of material objects are microphysical properties of their surfaces. We shall call this theory physicalism about color (physicalism, for short). In order to evaluate this theory, however, we shall first have to clarify some methodological issues. Our hope is that we can bring some further clarity to the question of color realism, whether or not we succeed in our critique of the physicalists' answer. (shrink)

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

The paper tries to rebut an objection to materialism. Anti-Materialists have argued that mental processes do not appear to be mere physical processes in the brain, And that secondary qualities such as sounds do not appear to be mere vibrations in the air. So materialists must admit that introspection and perception involve at least the illusion of the falsity of materialism. Using the headless woman illusion as a model, It is shown how the illusion is generated, And that it is (...) exactly what we ought to expect even if materialism is true. (shrink)

Locke’s argument for the primary-secondary quality distinction is compared with Descartes’s argument (in the Principles of Philosophy) for the distinction between mechanical modifications and sensible qualities. I argue that following Descartes, Locke’s argument for the primary-secondary quality distinction is an essentially a priori argument, based on our conception of substance, and the constraints on intelligible bodily interaction that this conception of substance sets.

Many of Margaret Cavendish’s criticisms of Thomas Hobbes in the Philosophical Letters (1664) relate to the disorder and damage that she holds would result if Hobbesian pressure were the cause of visual perception. In this paper, I argue that her “two men” thought experiment in Letter IV is aimed at a different goal: to show the explanatory potency of her account. First, I connect Cavendish’s view of visual perception as “patterning” to the “two men” thought experiment in Letter IV. Second, (...) I provide a potential reply on Hobbes’s behalf that appeals to physiological differences between perceivers’ sense organs, drawing upon Hobbes’s optics in De homine. Third, I argue that such a reply would misunderstand Cavendish’s objective of showing the limited explanatory resources available in understanding visual perception as pressing when compared to her view of visual perception as patterning.

In On the Genealogy of Color , Zed Adams challenges widely held philosophical views about the nature of color, exploring the relevance of the history of color science for contemporary debates in color realism/anti-realism and philosophy of mind. Adams argues that the two sides of the contemporary debate on the problem of color realism, Cartesian anti-realism and Oxford realism, are both predicated on an assumption that the concept of color perception is ahistorical and unrevisable. Adams takes issue with this premise (...) and traces the development of theories of color in order to undermine this assumption and open up the conversation about our perception of color. This book makes a significant contribution to recent debates on philosophical methodology by demonstrating the efficacy of using the genealogical method to explore philosophical concepts, and will appeal to philosophers of perception, philosophers of mind, and metaphysicians.

In The Subjective View,' I defended (unoriginally) a dispositional theory of color and drew out some consequences of that theory. The dispositional theory (DT) maintains, roughly speaking, that for an object to instantiate a color property is for it to have a disposition to cause experiences as of an object having that property in normal perceivers in normal conditions. This theory has notable merits in capturing (assuming one wants them captured) the subjectivity and relativity of ascriptions of color, while allowing (...) that it is external ob- jects themselves that are colored. It makes colors both sense depen- dent and object qualifying.2 But it runs into prima facie problems in giving a plausible account of the phenomenology of color percep- tion, as I ruefully observed in my earlier book (op. cit., pp. 132-37).
