Loosely put, colour constancy for example occurs when you experience a partly shadowed wall to be uniformly coloured, or experience your favourite shirt to be the same colour both with and without sunglasses on. Controversy ensues when one seeks to interpret ‘experience’ in these contexts, for evidence of a constant colour may be indicative a constant colour in the objective world, a judgement that a constant colour would be present were things thus and so, et cetera. My primary aim is (...) to articulate a viable conception of Present Constancy, of what occurs when a constant colour is present in experience, despite the additional presence of some experienced colour variation (e.g., correlating to a change in illumination). My proposed conception involves experienced colour layering – experiencing one opaque colour through another transparent one – and in particular requires one of those experienced layers to remain constant while the other changes. The aim is not to propose this layering conception of colour constancy as the correct interpretation of all constancy cases, but rather to develop the conception enough to demonstrate how it could and plausibly should be applied to various cases, and the virtues it has over rivals. Its virtues include a seamless application to constancy cases involving variations in filters (e.g., sunglasses) and illuminants; its ability to accommodate experiences of partial colours and error-free interpretations of difficult cases; and its broad theoretical-neutrality, allowing it to be incorporated into numerous perceptual epistemologies and ontologies. If layered constancy is prevalent, as I suspect it is, then our experiential access to colours is critically nuanced: we have been plunged into a world of colour without being told that we will rarely, if ever, look to a location and experience just one of them.

A dual referent approach to colour theory maintains that colour names have two intended, equally legitimate referents. For example, one might argue that ‘red’ refers both to red appearances or qualia, and also to the way red objects reflect light, the spectral surface reflectance properties of red things. I argue that normal cases of perceptual relativity can be used to support a dual referent approach, yielding an understanding of colour whose natural extension includes abnormal cases of perceptual relativity. This contrasts (...) with Peacocke’s multi-referent view, according to which such abnormal cases force us to introduce a wholly distinct kind of colour experience. I also argue that the two uses of colour names, arising from their two referents, have different extensions, even in normal perceptual circumstances, a consequence which conflicts with the heart of Rosenthal’s dual referent view.

I defend indirect perceptual realism against two recent and related charges to it offered by A. D. Smith and P. Snowdon, both stemming from demonstrative reference involving indirect perception. The needed aspects of the theory of demonstratives are not terribly new, but their connection to these objections has not been discussed. The groundwork for my solution emerges from considering normal cases of indirect perception (e.g., seeing something depicted on a television) and examining the role this indirectness plays in demonstrative assertions. (...) I argue that indirectness routinely if not typically plays a justificatory role in such judgements, and not a semantic one, and that the same can be said of such judgements when considered within the indirect realist framework. The denial of this, on my analysis, is essential to the criticisms of Snowdon and Smith. The discussion is extended to include scenarios involving the sorts of misconceptions Smith employs. (shrink)

Colour Relationalism asserts that colours are non-intrinsic or inherently relational properties of objects, properties that depend not only on a target object but in addition on some relation that object bears to other objects. The most powerful argument for Relationalism infers the inherently relational character of colour from cases in which one’s experience of a colour contextually depends on one’s experience of other colours. Experienced colour layering—say looking at grass through a tinted window and experiencing opaque green through transparent grey—demands (...) a contextual interdependency of one’s experience of one of these colours on one’s experience of the other. However, most if not all colour ontologies, and core perceptual experiential mechanisms like acquaintance and representation, can accommodate colour layering. It follows that experienced colour layering is consistent with colours being non-relational—this contextual interdependency of colours does not entail the constitutive dependency of one colour on the other. I utilize colour layering to examine the inference from the contextual to the constitutive interdependency of colours as it is employed in a well-known argument for Relationalism. I conclude that our justification for Relationalism is far weaker than Relationalists suggest. I first introduce readers to colour layering, then to Relationalism, and following this focus on the intersection of these topics. (shrink)

This essay is an introduction to the Routledge Handbook of Philosophy of Colour. Why has the examination of many different aspects of colour been a prominent feature in philosophy, to such an extent that the topic is worthy of a handbook? Here are two related answers. First, colours are exceedingly familiar, seemingly simple features that become enigmatic under scrutiny, and they are difficult to capture in any familiar-sounding, unsophisticated theory. Second, through colour one can confront various problems that span the (...) breadth of philosophy, including problems pertaining to perception, the mind-body relation, the nature of science, scepticism, vagueness, meta-ethics, and aesthetics. In this introduction we elaborate and guide the reader to the essays in the rest of this volume. (shrink)

Indirect realists maintain that our perceptions of the external world are mediated by our 'perceptions' of subjective intermediaries such as sensations. Multiple reference occurs when a word or an instance of it has more than one reference. I argue that, because indirect realists hold that speakers typically and unknowingly directly perceive something subjective and indirectly perceive something objective, the phenomenon of multiple reference is an important resource for their view. In particular, a challenge that A. D. Smith has recently put (...) forward for indirect realists can be overcome by appreciating how multiple reference is likely to arise when a projectivist variety of indirect realism is interpreted by speakers adhering to a naïve direct realism.

The claim that perceptual illusions can motivate the existence of sense-data is both familiar and controversial. My aim is to carve out a subclass of illusions that are up to the task, and a subclass that are not. It follows that when we engage the former we are not simply incorrectly perceiving the world outside ourselves, we are directly perceiving a subjective entity: one’s grip on the external world has been marginalized – not fully lost, but once-removed. However, admitting that (...) various illusions do not give evi¬dence for sense-data considerably limits the power of the argument from illusion (Section 6) and brings out its distinctness from the argument from perceptual relativity (Section 7). To reach these conclusions we will examine the role of ambiguity in perception (Section 3), its connection to illusion (Section 4), and the link reference has to every element of this dis¬course (Sections 2 and 5).

Intentionalism debates seek to uncover the relationship between the qualitative aspects of experience—phenomenal character—and the intentionality of the mind. They have been at or near center stage in the philosophy of mind for more than two decades, and in my view need to be reexamined. There are two core distinct intentionalism debates that are rarely distinguished (Sect. 1). Additionally, the characterization of spectrum inversion as involving inverted qualities and constant intentional content is mistaken (Sect. 3). These confusions can be witnessed (...) from an often-ignored and lonely perspective, that of the sense-datum theorist, and in particular of the projectivist (Sect. 2). In my view we have been so wary of sense-datum theory in recent years that we have failed to see that, even if false, it may permit perspectives on intentionalism issues difficult to occupy from other views.

We perceive the objective world through a subjective perceptual veil. Various perceived properties, particularly “secondary qualities” like colours and tastes, are mind-dependent. Although mind-dependent, our knowledge of many facts about the perceptual veil is immediate and secure. These are well-known facets of sense-datum theory. My aim is to carve out a conception of sense-datum theory that does not require the immediate and secure knowledge of a wealth of facts about experienced sense-data (§1). Such a theory is of value on its (...) own, given well-known challenges to epistemic foundationalism. Beyond this such a theory helps demonstrate how sense-datum theory can accommodate challenging perceptual phenomena like shape and size constancies (§3). These ideas are bridged by the roots of perceptual ambiguity (§2). In brief, tapering acquaintance knowledge creates space for perceptual representation to resolve the ambiguities in presented objects seemingly inherent in scenarios involving perceptual constancies. Thus, I offer a two-factor (acquaintance-representation) sense-datum theory to meet the challenge posed by constancies. Following Smith (2002), from whom this challenge is drawn, my focus is on shape and size constancies. Other constancies, notably colour constancy, are treated elsewhere (Brown 2014). (shrink)

I outline five issues in philosophy of colour that deserve greater attention and provide skeletal frameworks for how future work on these topics could be carried out. The issues are: colour and metaphilosophy, colour and artistic practice, colour and virtual/augmented reality, colour and imagination, and colour and the predictive mind. Some of these issues have been a focus of important recent works. Thus, colour conjoined with each of metaphilosophy, artistic practice and imagination have all been examined in at least a (...) few recent publications – see below for references. It is clear, however, that these recent works are signals that there is much still to be done. By contrast, while at present there is a great deal of interest in the predictive mind, the intersection of colour and the predictive mind is vastly underexplored. This is despite the fact that the philosophy and science of colour are rather developed disciplines. Finally, while there have been some very important recent works on virtual and augmented reality, the significance of colour for these studies has yet to be examined. It is my hope that after reading this article readers are convinced not only that the philosophy of colour has a rich, recent history, but also a very bright future. (shrink)

This is a review of Athanassios Raftopoulos "Cognition and perception: How do psychology and neuroscience inform philosophy?" (MIT Press, 2009). Raftopoulos defends the modularity of vision, i.e. early vision not penetrable by other processes. He maintains that early vision forms and outputs a kind of nonconceptual content to subsequent stages of vision and cognition. The work is heavily informed by visual neuroscience and embedded in familiar debates about scientific realism. It is also an important contribution to the now-popular debates about (...) the cognitive penetration of perception. (shrink)

This paper extends Jean-Luc Nancy’s engagement with St. Anselm. Specifically, while Nancy is primarily concerned with Anselm’s Proslogion, this paper brings Nancy’s deconstructive protocols to bear on Anselm’s Cur Deus Homo. Of particular interest is Nancy’s treatment of the semiological association of economics and metaphysics. Ultimately, the “supplemental logic” developed here allows us to read Anselm’s dependence on the category of debt in the context of prayer. Finally, by stressing Nancy’s reception of French literary theory and poststructuralism, this paper offers (...) an intervention into the burgeoning theological reception of Nancy, which generally sees him as a basically anti-Christian philosopher of Heideggerian, not Derridean, immanence.

The essays in this volume concern the points of intersection between analytic philosophy and the philosophy of the exact sciences. More precisely, it concern connections between knowledge in mathematics and the exact sciences, on the one hand, and the conceptual foundations of knowledge in general. Its guiding idea is that, in contemporary philosophy of science, there are profound problems of theoretical interpretation-- problems that transcend both the methodological concerns of general philosophy of science, and the technical concerns of philosophers of (...) particular sciences. A fruitful approach to these problems combines the study of scientific detail with the kind of conceptual analysis that is characteristic of the modern analytic tradition. Such an approach is shared by these contributors: some primarily known as analytic philosophers, some as philosophers of science, but all deeply aware that the problems of analysis and interpretation link these fields together.

From David Hume's famous puzzle about 'the missing shade of blue' to current research into the science of colour, the topic of colour is an incredibly fertile region of study and debate, cutting across philosophy of mind, epistemology, metaphysics and aesthetics as well as psychology. Debates about the nature of our experience of colour and the nature of colour itself are central to contemporary discussion and argument in philosophy of mind and psychology, and philosophy of perception. This outstanding Handbook contains (...) twenty-nine specially commissioned contributions by leading philosophers and examines the most important aspects of philosophy of colour. It is organised into six parts: The Importance of Colour to Philosophy The Science and Spaces of Colour Colour Phenomena Colour Ontology Colour Experience and Epistemology Language, Categories and Thought. The Routledge Handbook of Philosophy of Colour is essential reading for students and researchers in philosophy of mind and psychology, epistemology, metaphysics and aesthetics, as well as for those interested in conceptual issues in the psychology of colour.

Many business and government institutions appear to have failed in meeting society’s expectations of them. Continuing scandals and failures, as well as an increasingly obvious lack of responsibility to customers, have caused communities to question the probity and operation of these organisations. Consequently, “social licence to operate” is becoming an increasingly common process and one which demands a change in management philosophy and behaviour in our institutions. Improving the quality of responsible management practice is a critical element in this new (...) management philosophy, and which demands an intense focus on including ethical considerations in the core management competence of decision-making. We draw on a combined 100-plus years of international consulting experience, “C“ and senior executive work experience, and academic research to present a practical framework for responsible management practice which, we believe, can also form the foundation for the required organisational cultural transformation required of many existing organisations.

ABSTRACT This article reinscribes a question asked by J. Hillis Miller nearly a decade ago: How can Derrida's political thought help us today? It answers this question by reading Derrida's treatment of the relationship between citationality and event, especially as this relationship is articulated in 9/11 and in autoimmune responses to 9/11—which continue to plague “us” today. In short, the citational structure of 9/11 demands that our responses to this trauma be “kept open” to the future and to the democracy (...) to come. Desires for nationalisms and walls are so many attempts to close off this openness, this future: desires to deny the citational structure of the event. (shrink)

This paper supports the burgeoning movement that looks to find affinities between Hans urs von Balthasar's theology and various liberation theologies. It does so by offering a “recontextualization” of Balthasar's thought. Specifically, it provocatively looks to recontextualize Balthasar as a theologian of the street. The argument proceeds in three stages: First, the meaning of “context,” and so the possibility of recontextualization, is discussed. While the term has become commonplace in contemporary “contextual theologies,”, the most rigorous analysis of context is found (...) not in theology, but in literary theory. Second, the particular locale of this particular recontextualization is discussed: the street. As sign, the street is ideologically and metonymically overdetermined. Here, Derrida, Goizueta, and Maeseneer are given as examples of thinkers who think with or from the street, who are contextualized by the street. Finally, the paper turns to specific instances in Balthasar's text that demonstrate his street contextualization: namely, his criticism of Rahner's martyrless Christianity and his discussion of the saints, particularly Joan of Arc. This section rejects those claims, epitomized by Murphy, that Balthasar's name signs a totally conservative context, and so completes my project of freeing space for the aforementioned liberatory movement to continue blossoming.
