Abstract:
This chapter tackles the problem of finding data-derived indicators to measure the quality of peace, versus a definition of peace simply as the absence of war. Conceptually, peace is seen as an equilibrium condition where resort to violence is minimal and where the highest quality of peace exists when the idea of armed violence approaches the unthinkable. The author draws upon the early work of Quincy Wright and Kenneth Boulding and progresses from there, establishing first their definitions of and conditions for peace. To put his theories to work, he introduces two proxy indicators: black market currency exchanges and bond market prices. Specifically, he examines and compares the premiums attached to the black market values of currencies in less stable economies and relates them to factors that promote destabilization of the equilibrium. Similarly, he compares the strip spreads on sovereign bonds as an indicator of government stability and instability.

Abstract:
The Quality of Life: Aristotle Revised presents a philosophical theory about the constituents of human well-being. It begins with Aristotle’s thoughts about this topic, but often modifies and sometimes rejects them. The principal idea is that what Aristotle calls “external goods” (wealth, reputation, power) have at most an indirect bearing on the quality of our lives. A good internal life—the way in which we experience the world—is what well-being consists in. Pleasure is one aspect of this experience, but only a small part of it. Far more valuable is the quality of our emotional, intellectual, social, and perceptual experiences. These aspects of our existence make it potentially richer and deeper than the quality of life available to many other animals. A good human life is immeasurably better than that of a simple creature that feels only the pleasures of nourishment. Even if it felt pleasure for millions of years, human life would be superior. Contemporary discussions of well-being often appeal to a thought experiment devised by Robert Nozick, which holds that we should not attach ourselves to an “experience machine”—a device that manipulates our brains and gives us any illusory experiences of our choosing. This is thought to show that one’s interior life has little or no value on its own; that we must live in “the real world” to live well. In fact, however, this thought experiment supports the opposite conclusion: the quality of our lives consists in the quality of our experiences.

Abstract:
The property which perceptual experiences of a given phenomenal kind enable the subject to track is not always identical with the property objects appear to have (in a phenomenally manifest manner) in the kind of experience at issue. Tracked properties and apparent properties come apart in colour perception but they are identical in the perception of three-dimensional shape. In order to defend these claims, this chapter proposes a criterion for the identity of tracked property and apparent property in a given experience. The view developed leads to an account of the traditional distinction between primary and secondary qualities. In order to capture what it is to instantiate a given secondary quality, one must specify the phenomenal kind of perceptual experience an instantiation of the property would render veridical.

Abstract:
This chapter suggests that, when considering the philosophical problem of other minds, we distinguish between "thick" and "thin" versions of it. While traditional approaches take the problem to be a thick one, more recent work can be seen as addressing only a thin variant. Dretske, while acknowledging the thick problem, proposes a perceptual model of our knowledge of other minds which addresses only the thin version. The chapter proposes that, in the place of the thick problem, we consider the quality of our interactions with others. Following Wittgenstein, it suggests that where individuals share a nature their interactions exhibit a quality that it calls "depth." Where that nature is not, or is only partially, shared, there one might expect to find the quality of the interaction between persons disturbed. The chapter suggests that this disturbance might explain the impaired quality of interaction between autistic and non-autistic individuals.

Abstract:
Chapter 6 exploits the thesis that perception is constitutively a matter of employing perceptual capacities to address the problem of consciousness. Orthodox views analyze consciousness in terms of sensory awareness of some entities. The relevant entities have been understood to be (1) strange particulars, such as sense-data, qualia, or intentional objects, (2) abstract entities, such as properties, or (3) mind-independent particulars in our environment, such as objects, property-instances, and events. There are problems with all three versions of the orthodox view. Chapter 6 breaks with this orthodoxy. It argues that perceptual consciousness is constituted by a mental activity, namely the mental activity of employing perceptual capacities. I call this view mental activism. Insofar as employing perceptual capacities constitutes representational content, mental activism is a form of representationalism, one on which a substantive explanation is given why and how consciousness is grounded in representational content.

Abstract:
This chapter presents a general theory of color perception that focuses on something close to what Wilfred Sellars called “the sensory core”, something well-described in a passage from H. H. Price’s Perception. It develops the implications of that theory for (i) the distinctive epistemology of perception, which in the best case involves something better than mere knowledge, (ii) the nature of ganzfelds, film color, highlights, lightened and darkened color, auras, after-images, color hallucinations and the like, (iii) the account of when things are predicatively colored, and (iv) the nature of the category of quality. The chapter argues that as a consequence of understanding the sensory core we should reject the two most influential views in the philosophical theory of perception. Our most basic perceptual experiences are not adequately modeled as attitudes directed upon propositions. Nor are they adequately modeled as directed upon facts, understood as items in our perceived environment.

Full text
Abstract:
This chapter provides an overview of the debate about the phenomenal presence of features in perceptual experience. First, it delineates the theme of the volume by characterizing phenomenal presence and drawing four important related distinctions: (i) between the phenomenal presence of features pertaining to the objects of experience and features pertaining to the experiences themselves; (ii) between sensory and non-sensory phenomenal presence in perceptual experience; (iii) between the phenomenal presence of features of objects that are in view and of objects that are out of sight; and (iv) between qualitative and categorical features of perceptual experiences. Then, the chapter contrasts the debate about phenomenal presence with the closely related debates about intrinsic qualia, cognitive phenomenology, and higher-level perception. Finally, it provides detailed descriptions of the content of the contributions to the volume and highlights their main claims and their philosophical significance for the debate about phenomenal presence and beyond.

Abstract:
Projectivism asserts that we project subjective aspects of perception into what we experience as the world outside ourselves. It is minimally familiar from various phantom pains, afterimages, and hallucinations. Views like sense-datum theory arguably assert a more global, Strong Projectivism: all perceptual experiences involve and only involve direct awareness of projected elements. Strong Projectivism is an underappreciated variety of intentionalism. It straightforwardly explains the transparency of experience, and phenomena qualia theorists offer to avoid intentionalism, including blurry vision and spectrum inversion. Finally, projectivism illuminates residual qualia-friendly cases involving imagination and emotion. Although some cases may provide instances of non-projected, non-intentional aspects of experience, most do not. Thus, the notion of phenomenal presence drawn from projectivism does justice to a great many of the forces at play in debates surrounding qualia and intentionalism. We should bound toward Strong Projectivism.

Abstract:
Following an initiative of the early 1990s, the majority of United Kingdom cathedrals now have girl as well as boy cathedral choristers, often alternating in the singing of the daily services. One of the original political challenges in this musico-cultural initiative was whether or not it was possible for girl choristers to attain the same vocal quality as their male counterparts. Empirical studies, however, suggest that there is considerable overlap between the psycho-acoustic vocal features of girls’ and boys’ singing, such that it is often difficult perceptually to distinguish between the two, particularly for the relatively naïve listener. Moreover, the music repertoire usually reaches across gender. The chapter provides an overview of these recent developments and explores how the musical director can best shape the vocal products of their choristers, while being sensitive to particular vocal production issues that relate to the development of girls’ voices.

Full text
Abstract:
Sensuous imaginative content presents a problem for unitary accounts of phenomenal character (or content) such as relationism, representationalism, or qualia theory. Four features of imaginative content are at the heart of the issue: its perspectival nature, the similarity with corresponding perceptual experiences, the multiple use thesis, and its non-presentational character. This chapter rejects appeals to the dependency thesis to account for these features and explains how a representationalist approach can be developed to accommodate them. The author defends the multiple use thesis against Kathleen Stock’s objections but separates the putative non-presentational character of imaginative content into two elements. Loss of presentation is accounted for by the reduced representations involved in imagination and lack of potential response-dependent representational properties. Absence of commitment to reality is accounted for by representational properties characterized in terms of the absence of a certain kind of aetiology.

Abstract:
Communication requires interdependent functioning of large portions of the brain, and damage to any of these systems can disrupt effective and appropriate communication. Damage to the right hemisphere or basal ganglia can result in difficulty using or understanding prosodic contours in speech. Prosody includes pitch, loudness, rate, and voice quality, and is used to convey emotional connotation or linguistic intent. A disorder in the comprehension or production of prosody is known as aprosodia; affective aprosodia is a specific deficit affecting emotional or affective prosodic contours. The right hemisphere has been shown to play a critical role in processing emotional prosody and aprosodia syndromes resulting from damage to right hemisphere areas have been proposed. These include an expressive aprosodia resulting from anterior damage and a receptive aprosodia resulting from more posterior damage. Assessment and diagnosis of aprosodia in clinical settings are often perceptually based; however, acoustic analyses of means and ranges of frequency, intensity, and rate provide an instrumented analysis of prosody production. The treatment of aprosodia following stroke has received scant attention in comparison to other disorders of communication, although a few studies investigating cognitive–linguistic and imitative treatments have reported some positive results.
