This volume of translations unites three shorter works by Arthur Schopenhauer that expand on themes from his book The World as Will and Representation. In On the Fourfold Root he takes the principle of sufficient reason, which states that nothing is without a reason why it is, and shows how it covers different forms of explanation or ground that previous philosophers have tended to confuse. Schopenhauer regarded this study, which he first wrote as his doctoral dissertation, as an essential preliminary (...) to The World as Will. On Will in Nature examines contemporary scientific findings in search of corroboration of his thesis that processes in nature are all a species of striving towards ends; and On Vision and Colours defends an anti-Newtonian account of colour perception influenced by Goethe's famous colour theory.

This paper argues for two major revisions in the way philosophers standardly think of vision science and vision theories more generally. The first concerns mental representations and the second supervenience. The central result is that the way is cleared for an externalist theory of perception. The framework for such a theory has what are called Aristotelian representations as elements in processes the well-functioning of which is the principal object of a theory of vision.

Wilber's most timely, accessible, and practical work to date. Here is a concise, comprehensive overview of Wilber's revolutionary thought and its application in today's world. Wilber has long been hailed as one of the most important thinkers of our time, but--until now--his work has seemed inaccessible to the general reader who lacks a background in consciousness studies or evolutionary theory. Integral Vision will allow a general audience to fully understand what all the excitement has been about. In clear, (...) non-technical language, Wilber presents complex, cutting-edge theories and models that integrate the realms of body, mind, soul, and spirit. He then demonstrates how these theories and models can be applied to real world problems. Finally, Wilber discusses daily practices that readers take up in order to apply this integrative vision to their own, everyday lives. Wilber begins by presenting a leading model of human evolution, a model called "spiral dynamics." He then goes on to summarize his ground-breaking "all-level, all-quadrant" model for integrating the seemingly contradictory realms of science and religion--the "all-level, all-quadrant" model has already been adopted by leading thinkers in a variety of fields. In a chapter entitle "The Real World," Wilber shows how these rather abstract theories and models are being applied to real-world issues such as politics, medicine, business, education, and the environment. Wilber goes on to present a collection of maps of the Kosmos. These are broader models that can integrate the various worldviews that have been developed around the world throughout the ages. The final chapter of the book, "One Taste," proposes that readers take up an "integral transformative practice" such as meditation to help them to apply and develop this integral vision in their personal, everyday lives.

This essay attempts to develop a psychologically informed semantics of perception reports, whose predictions match with the linguistic data. As suggested by the quotation from Miller and Johnson-Laird, we take a hallmark of perception to be its fallible nature; the resulting semantics thus necessarily differs from situation semantics. On the psychological side, our main inspiration is Marr's (1982) theory of vision, which can easily accomodate fallible perception. In Marr's theory, vision is a multi-layered process. The different (...) layers have filters of different gradation, which makes vision at each of them approximate. On the logical side, our task is therefore twofold - to formalise the layers and the ways in which they may refine each other, and. (shrink)

As a complement to his version of Euclid’s Optics, the Portuguese mathematician Francisco the Melo (1490-1536) wrote a short treatise on the principles of vision that also included a summary description of the components of the eye. Combining arguments of geometric and anatomical nature, that text helps us to understand some of the conflicting ideas of the Renaissance period, before Kepler, but it also invites us to reread the contributions of a number of authors from the Middle Ages, with (...) a particular focus on Alhacen and Witelo. Although Melo's theory of vision cannot be classified as exactly groundbreaking, it presents many interesting and singular peculiarities. In particular the way in which Melo justifies the existence of rays emitted by the eye while incorporating, at the same time, some elements of the intromission theories, and the clear steps he gives to single out the perpendicular ray in the mechanism behind a faithful and distinct vision.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 265 concluding chapter (pp. 150-52), Dr. Clair deals with "Comment lire l'oeuvre du P. Thomassin," providing much guidance to anyone who wishes to avail himself of the rich resources in Thomassin's writings. From the point of view of the history of philosophy, the most interesting aspects of Thomassin's thought seem to be (1) his "Cartesianism," that is, the extent to which he early imbibed Descartes' new ideas, (...) and played a role in the fusion of the views of Augustine, B6rulle, and Descartes that developed in the Oratory, (2) his attempt to find a viable theory of the nature of Grace somewhere between Arnauld and Malebranche, and (3) his efforts to formulate a philosophy of history within an Augustinian theology; a philosophy of history that would make historical research and understanding of genuine philosophical and religious value to man. Dr. Clair's too brief discussions indicate that Thomassin was definitely influenced by reading Descartes, but also that Thomassin was much too eclectic to be a Cartesian. With regard to the problem of Grace, where the Cartesian Arnauld fought with the semi-Cartesian Malebranche, Thomassin tried deftly to maintain an Augustinian position that was not quite as rigid as that of the Jansenists, nor as moderate as that of Malebranche (though Arnauld tried to use Thomassin's erudition and authority in his battles with Malebranche). Unfortunately Dr. Clair does not try to evaluate whether Thomassin really found a coherent and theologically acceptable middle-ground between the two antagonists. On the subject of the philosophy of history, Thomassin's views seem most interesting (at least to this reviewer). The short text that Dr. Clair includes on the difference of history from science reveals Thomassin trying to show that the investigation and comprehension of temporal particulars can have significant value for man's understanding of man and that there can be genuine certainty about past facts. Thomassin was writing in the period when modern historical method and outlook were born, when historical study changed from chronicles and ammunition in theological and political disputes to a basic way of understanding human nature. Those concerned with the role of Bayle, Hume, Gibbon, and Vico in developing an historical methodology and a rationale for art historical approach to human problems might well profit from considering Thomassin's writings in this area, and the influence they had on modern historiography and philosophies of history. Dr. Clair's short work certainly helps in filling a lacuna in our picture of the seventeenth century. It also makes one wish he had done more, and had provided a "complete" study of Thomassin's thought and influence. That, perhaps, is one of the major purposes of this new series, in that it will lead scholars to looking into the more hidden portions of the period, and will lead them to filling out in more detail and depth the history of the rise and fall of modern philosophy. It is to be hoped that future volumes in this series will continue to whet our appetites for further investigations, and will transform more of the names we run across into figures about whom we have some information and from whom we can still learn something.

George Berkeley argues that vision is a language of God, that the immediate objects of vision are arbitrary signs for tactile objects and that there is no necessary connection between what we see and what we touch. Thomas Reid, on the other hand, aims to establish a geometrical connection between visible and tactile figures. Consequently, although Reid and Berkeley's theories of vision share important elements, Reid explicitly rejects Berkeley's idea that visible figures are merely arbitrary signs for (...) tangible bodies. But is he right in doing so? I show that many passages in Berkeley's work on vision suggest that he acknowledges a geometrical connection between visibles and tangibles. So the opposition between the arbitrariness Berkeley defends and a geometrical connection cannot be as universal as Reid thinks. This paper seeks to offer a plausible reading of Berkeley's theory of vision in this regard and an explanation of why Reid interprets Berkeley differently. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A THEORY OF BASIC GOODS: STRUCTURE AND HIERARCHY* I. FTEN, PERHAPS ALWAYS, moral theory emerges from particular problems. Just how is obscure. The logic of discovery is elusive; and it is harder to explain how we have come to see matters rightly than to recognize that we do, in fact, see them rightly. What counts as a theory, moreover, calls for explication as much as does (...) a theory's emergence. When we have in mind a theory that shapes our social vision, there is a progression from a central set of propositions, keyed to a range of paradigm cases and seen as a logical structure, to a " way of thinking " widely enough embraced to have political significance, at least for a given oommunity. In this essay I want to explore some fundamental questions raised by Germain Grisez's theory of natural law ethics.1 These questions are chiefly conceptual. But neither they nor Grisez's theory should be seen in a vacuum. Rather, I would begin by suggesting that the importance of his work, its emergence in some Catholic circles, is linked with two specific moral and political problems. The first is abortion; the second is the superpowers' policy of nuclear deterrence. *I thank David Blake, Robert Gordh, Carroll Kearley, Gary Mar. Martin Woods, and Linda Zagzebski for their comments on an earlier version of this essay. 1 For the theory's fullest presentation, see Germain Grisez, The Way of the Lord Jesus, vol. one, Ohristian Moral Principles, with the help of Joseph M. Boyle, Jr., Basil Cole, O.P., John Finnis, John A. Geinzer, Robert G. Kennedy, Patrick Lee, William E. May, and Russell Shaw (Chicago: Franciscan Herald Press, 1983). Especially critical are chapters two through twelve. 221 JAMES G. HANINK As a point of chronology, Grisez's early study of rubortion was the context for one of the first formulations of his natural law ethics.2 But why should this have been so? And why should abortion so engage Catholic thinkers, some of whom had felt a distance from explicitly Catholic positions, that Grisez's work should become pivotal? Answers to such questions must be tentative, but they include the following considerations. In a brief period, no more than a decade, legal abortion in the West became entrenched social policy.8 It was a policy, too, supported by dominant intellectual forces. But the new policy, defended in terms of individual freedom and a right to privacy, struck many Catholicsand non-Catholics-as vicious and tragic. It was vicious in that it made expendable the weakest and most vulnerable human beings. Human rights somehow became restricted to the strong and self-sufficient. The policy was tragic in its denial of human community. We are not, however much radical individualism supposes, merely a collection of separate egos. l/Ve are, rather, a community tied to a past and pledged to a future, so pledged, in part, by the children we bear and nurture.4 For in hearing and nurturing children we carry on the love of parents who have done as much for us; and we carry ourselves into a future where we hope our own love will be thus extended. But abortion, and surely unrestricted abortion, betrays this community of trust. Still, a policy so vicious and tragic can make us look for a fresh moral vision. And, of course, to the extent that we have contributed to,a climate in which abortion could become entrenched -either by our failures to support women in need or 2 Germain Grisez, Abortion: The Myths, the Realities, and the Arguments (New York and Cleveland: Corpus Books, 1970). a A milepost, of course, was the United States Supreme Court decision, Roe v. Wade, in 1973.

Reid maintained that the perceptions that we obtain from the senses of smell, taste, hearing, and touch are ‘suggested’ by corresponding sensations. However, he made an exception for the sense of vision. According to Reid, our perceptions of the real figure, position, and magnitude of bodies are suggested by their visible appearances, which are not sensations but objects of perception in their own right. These visible appearances have figure, position, and magnitude, as well as ‘colour,’ and the standard view (...) among Reid scholars has been that Reid maintained that our perceptions of visible figure, position, and magnitude are also not suggested by any sensation. They are instead suggested by the material impression on the retina. Gideon Yaffe challenges the standard interpretation. According to Yaffe, Reid believed that our perceptions of visible figure are suggested by corresponding sensations, by sensations of colour. We defend the standard interpretation of Reid. According to Reid, there is no “local sign” in our sensations of colour. The same colour sensation can be associated with different positions on the visual field, and different colour sensations can be associated to the same position on the visual field. According to Reid, we only have evidence for a correlation between the image on the retina and the perception of visible figure. (shrink)

This paper examines Henry Giroux’s critical pedagogy, and explores the interconnections among education, democracy, and hope. Whereas critical pedagogy rejects foundationalism, it still requires a normative foundation to criticise oppressive situations and pose a vision of the future. Giroux rejects foundationalism and regards oppressive force such as neoliberalism as an enemy of both hope and democracy. He regards hope as an act of imagination, something to be cultivated, which can be regarded as a medium of mobilisation. This seems inconsistent (...) with the tenets of critical pedagogy, as mobilisation is often thought to suppress individual human agency, which Giroux and other critical pedagogues have emphasised heavily. This paper solves this inconsistency via the radical democracy advocated by Ernesto Laclau and Chantal Mouffe and Gramscian insights regarding hegemony and education, and redefines the role of hope in Giroux's theory. Giroux’s framing of hope moves us towards certain normative claims and mobilises people to desire democracy as a normative foundation for society. (shrink)

In Section 38 of the Theory of Vision Vindicated, George Berkeley claims that he had used the method of analysis throughout the Theory of Vision. What does that mean? I first show that "analysis" denoted a fairly well-defined method in the early modern period: it was regularly described as a method of discovery. Then I show that the discussion of distance perception in the Theory of Vision exemplifies the method of analysis and may be (...) seen as a modification of a non-geometrical account of distance vision in Rene Descartes' Optics.

This paper considers the implications of David Marr's computational theory of vision for the issues of individualism and methodological solipsism. A recent argument that the theory is nonindividualistic is shown to be similar to Gibson's arguments for "direct perception." The paper argues that a complete analysis of Marr's theory must take into account Marr's rejection of Gibson's approach, and that such an analysis shows Marr's theory to be consistent with methodological solipsism as a research strategy.

By "transparency" with respect to Berkeley's theory of signs, I mean the notion that because of the often close association between signs and what they signify, we mistakenly think we sense what is signified by the sense that accesses the sign.

David Marr's theory of vision has been widely cited by philosophers and psychologists. I have three projects in this paper. First, I try to offer a perspicuous characterization of Marr's theory. Next, I consider the implications of Marr's work for some currently popular philosophies of psychology, specifically, the "hegemony of neurophysiology view", the theories of Jerry Fodor, Daniel Dennett, and Stephen Stich, and the view that perception is permeated by belief. In the last section, I consider what (...) the phenomenon of vision must be like for Marr's project to succeed. (shrink)

This essay, published shortly before the 2020 U.S. presidential election (mired in controversy over a potential judicial appointment to the Supreme Court), celebrates Daniel Callahan's prescient book Abortion: Law, Choice and Morality. Nothing could be timelier. Callahan's central question was the “moral and social” struggle requisite for coherent policies and laws regulating abortion. He rejected “one‐value” positions and strove to develop an expansive middle ground. He decried emotion untutored by reason, crude polemics, and bludgeoning: his recipe for a “noxious brew.” (...) Callahan's way of thinking preceded the development of a critical health humanities, the advent of moral foundations theory in psychology, and the philosophical concept of a moral imagination. Each of these inheres in his rigorous approach to the abortion problem. His honesty and humility led to a sea change in his position on abortion. Fifty years later, much can still be learned from Callahan's arguments—about abortion and other bioethics issues—most importantly, in how we address wider social issues in these polarized times.

Vision has dominated philosophical thinking about perceptual experience and the nature of its objects. Color has long been the focus of debates about the metaphysics of sensible qualities, and philosophers have struggled to articulate the conditions on the visual experience of mind-independent objects. With few notable exceptions, "visuocentrism" has shaped our understanding of the nature and functions of perception, and of our conception of its objects. The predominant line of thought from the early modern era to the present is (...) that, in the philosophically interesting respects, as things are with vision, so they are with hearing, touch, olfaction, and the rest. A closely related line of thought has been particularly strong in the case of the secondary qualities. (shrink)

I consider the geometrical structure of the apparent visual field. Although the optics of vision is well understood, the nature of visual awareness remains largely in the dark. A famous attempt at a formal description of the apparent visual field was by Helmholtz, in the late nineteenth century. It purportedly explains the phenomenon of the subjective curvatures often reported when viewing objectively straight lines of great extent. I consider the general problem, and suggest an alternative formal account. On phenomenological (...) grounds the very existence of a coherent geometry may be doubted. Yet, although seemingly an academic question, the issue has very real consequences. The two models I consider here may approximately apply to certain visual modes. The nature of such visual modes is discussed. (shrink)

Berkeley's Theory of Vision, or Visual Language Showing The Immediate Presence and Providence of A Deity, Vindicated And Explained was published in 1733, occasioned by an anonymous letter of the previous year to the London Daily Post Boy .

No one has ever identified the author whose criticisms led Berkeley (...) to his Theory of Vision Vindicated . Circumstantial evidence presented here suggests that the author was Catherine Trotter Cockburn. Part of the evidence is the brilliance of her interpretation of Locke, whose position is defended in the letter against Berkeley. (shrink)

The sensorimotor theory of vision is the best attempt yet to explain visual consciousness without implying a Cartesian theatre. I suggest three experiments which might test the theory.

William Storm reinterprets the concept of the tragic as both a fundamental human condition and an aesthetic process in dramatic art. He proposes an original theoretical relation between a generative and consistent tragic ground and complex characterization patterns. For Storm, it is the dismemberment of character, not the death, that is the signature mark of tragic drama. Basing his theory in the sparagmos, the dismembering rite associated with Dionysus, Storm identifies a rending tendency that transcends the ancient Greek setting (...) and can be recognized transhistorically. The dramatic character in any era who suffers the tragic fate must do so in the manner of the ancient god of theater: the depicted self is torn apart, figuratively if not literally, psychologically if not physically. Storm argues that a newly objectified concept of the tragic can prove more useful critically and diagnostically than the traditional and more subjective tragic "vision." Further, he develops a theory of the tragic field, a model for the connective and cumulative activity that brings about the distinctive Dionysian effect upon character. His theory is supported with case studies from Agamemnon and Iphigenia in Aulis, King Lear, and The Seagull. Storm's examination of the dramatic form of tragedy and the existential questions it raises is sensitive to both their universal relevance and their historical particularity. (shrink)

The chapter revolves around Tyler Burge's interpretation of David Marr's theory of vision, and the chapter's arguments against such construal. Burge asserts that through evolution, our sensory systems have become adapted to our current environment, and can be assumed to be “successful” in that we are able to generate veridical perceptions of the same. According to Burge, this ascribes a “success-orientation” to Marr's theory. This chapter argues that Marr's own assumption of success in his work is merely (...) a methodological dictate necessary to solve or understand the initial query and purpose of the study. In the same way that artificial intelligence is developed, one has to make intelligent choices on which types of human cognitive abilities should the project be patterned after. Thus, Marr's employment of this practice does not automatically warrant the assumption of veridical perception in his work. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"Magic Buffalo" and Berkeley's Theory ofVision: Learning in Society David M. Levy Introduction Berkeley's Theory of Vision contains the remarkable claim that the perception ofdistance is learned by experience. This thesis is rooted in Berkeley's doctrine that the physical basic of optical perception is angular. An impression of angle? impacts upon the optic nerve. The interpretative problem confronting an individual is that of reconstructing two pieces (...) ofinformation, distance d and magnitude m, from one datum T. Let the ratio ofm/d form arctan T. How do we come to distinguish between the pair m1,d1 and the pair m2,d2 when m^d 1 = m2/d2? How do we distinguish big objects at a distance from small objects up close? The evidence Berkeley provides for this thesis is of a funny sort. He gives examples that we do, in fact, distinguish large distant objects from small near objects. Since the arctan of the pair m1, d 1 is by hypothesisthe sameas thatofthepairm2, d2thenrecognizingdistance must be alearned abihty. We cannotextractd and m from? alone. The proper interpretation ofBerkeley's philosophy ofscience is a matter of considerable debate.1 Nonetheless, as a working theorist of visual perception he is afairly simple-minded falsificationist. Here is what he says: find a person born blind who comes by surgery to see. If that person can distinguish at a glance big distant objects from small near objects, 111 amend my theory.2 The literature on Berkeley's Theory ofVision can be fairly said to bifurcate between those who "see" the argument and those who don't. Berkeley's most important eighteenth century disciple, Adam Smith, extended Berkeley's teaching to encompass the remarkable claim that we learn to perceive our economic interest (Levy 1992a, 1992b). The negative reaction to Berkeley's theory starts in 1842 with Samuel Bailey who pronounced himself mystified by the very claim that we learn to perceive distance. The debate between Bailey and John Stuart Mill, a debate which has twentieth century counterparts, has all the characteristics ofpeople talking past each other. Volume XLX Number 1 223 DAVID M. LEVY The missing social dimension The problem, as I see it, with Berkeley's proposed critical test—stipulating his own doctrine—is that a blind person would grow up in a sighted community. Perhaps, if he grew up in a blind community, and most of the community became sighted at the same time he did, all the community might be able to perceive distance. The problem with Berkeley's test is that ifhe himself is correct about the importance ofheuristics in making the visual distinctions, the fate of one individual is somewhat beside the point. One individual surely cannot create the necessary heuristics. This learning requires some evolutionary social process. Thus, while Berkeley's thesis requires some claim about some verybasicsocial epistemology(Fuller 1988), his proposed test, asking about a blind person growing up in a community silently presumed to be sighted, does not take into account the social dimension oflearning. Having said this, it is easy to think ofa better test for Berkeley's theoryofvision. Let us find an entire community where life takes place without the visual perception of great distance. Take any individual from this community and ask Berkeleian questions. Now, we know the answer becausejust such a dialogue was reported thirtyyears ago. One society which fulfils the test criterion is that ofthe BaMbuti people who lived their life in a very dense African forest. The American anthropologist Colin Turnbull took his friend from the BaMbuti, Kenge, to the top of a hill. Here is TurnbuH's famous report: Then he saw the buffalo, still grazing lazily several miles away, far downbelow. He turned to me and said, "Whatinsects are those?" At first I hardly understood; then I realized that in the forest the range of vision is so limited that there is no great need to make an automatic allowance for distance when judging size. Out here in the plains, however, Kenge was looking for the first time Over apparently unending miles of unfamiliar grasslands, with not a tree worth the name to give him any basis for comparison. The same thing happened later on... (shrink)

Schopenhauer is famous for his pessimism. Many people are surprised to learn that he articulated an important theory of laughter. While this theory has been scrutinised by aestheticians exploring the nature of humour, little has been written on the role of laughter in Schopenhauer’s pessimistic vision of the world. Admittedly, this latter topic is only a minor theme in Schopenhauer’s work: yet I contend that what he has to say illuminates the human predicament.
