Recent advances in molecular biology and microanatomy have supported homologies of body parts between vertebrates and extant invertebrate chordates, thus providing insights into the body plan of the proximate ancestor of the vertebrates. For example, this ancestor probably had a relatively complex brain and a precursor of definitive neural crest. Additional insights into early vertebrate evolution have come from recent discoveries of Lower Cambrian soft body fossils of Haikouichthys and Myllokunmingia (almost certainly vertebrates, possibly related to modern lampreys) and Yunnanozoon (...) and Haikouella (evidently stem-group vertebrates). The earliest vertebrates had an unequivocally marine origin, probably evolved mineralised pharyngeal denticles before the dermal skeleton, and evidently utilised elastic recoil of the visceral arch skeleton for suction feeding. Moreover, the new data emphasise that the advent of definitive neural crest was supremely important for the evolutionary origin of the vertebrates.

Hagfishes have long held a key place in discussions of early vertebrate evolution. Frustratingly, one basis for such discussions—namely hagfish embryology—is very incompletely known, because the embryos of these animals are notoriously difficult to obtain.1,2 Fortunately, a recent publication on a Far Eastern hagfish3 describes a workable procedure for obtaining embryos and then uses this precious material to show that the hagfish neural crest arises by cell delamination as in other vertebrates—and not by epithelial outpouchings from the wall of the (...) neural tube as previously claimed.4 Importantly, because hagfish embryos should now be available on a regular basis, the way is open for additional morphological and developmental genetic investigations to help evaluate existing evolutionary scenarios and perhaps suggest new ones.

In this posthumously published novel, Layers, Nathaniel Branden exhibits his talent as not only a philosopher and psychotherapist, but also a writer of fiction. The plot primarily involves the story of Nicholas Holland, a published author and leading therapist, as he interacts with Andrew Berringer, to whom he has come for therapy.

Scholarship on Quintus Smyrnaeus has long moved past the point where he is considered nothing more than an ‘artificial imitator of a bygone age’. Rather, scholars generally recognize the dynamism of Quintus’ relation to Homer, as can be seen in the subtitles of two volumes on Quintus published in the past few years:Engaging Homer in Late AntiquityandTransforming Homer in Second Sophistic Epic. Even in passages that are clearly modelled on passages in Homer, Quintus is no longer seen as slavishly imitating (...) but as creatively rereading and re-imagining his works. Calum Maciver, perhaps Quintus’ most vocal champion, sums this approach up nicely, arguing that ‘Quintus imitates, manipulates, comments on, differs from, in sum reads, Homer’, and describing the epic as ‘a demanding text with intricate possibilities for interpretation’. And Maciver is hardly alone in this; various studies in recent years have shown that Quintus’ use of Homer reflects his own values and preoccupations, and those of his society. (shrink)

Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In _Humanity's End,_ Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines (...) the proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve "longevity escape velocity"; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.

In the first in-depth philosophical study of the subject, Nicholas Gier examines the published and unpublished writings of Ludwig Wittgenstein, to show the striking parallels between Wittgenstein and phenomenology. Between 1929 and 1933, the philosopher proposed programs that bore a detailed resemblance to dominant themes in the phenomenology of Husserl and some “life-world” phenomenologists. This sound, thoroughly readable study examines how and why he eventually moved away from it.

Our understanding of communication and its evolution has advanced significantly through the study of simple models involving interacting senders and receivers of signals. Many theorists have thought that the resources of mathematical information theory are all that are needed to capture the meaning or content that is being communicated in these systems. However, the way theorists routinely talk about the models implicitly draws on a conception of content that is richer than bare informational content, especially in contexts where false content (...) is important. This article shows that this concept can be made precise by defining a notion of functional content that captures the degree to which different states of the world are involved in stabilizing senders’ and receivers’ use of a signal at equilibrium. A series of case studies is used to contrast functional content with informational content, and to illustrate the explanatory role and limitations of this definition of functional content. _1_ Introduction _2_ Modelling Framework _3_ Two Kinds of Content _3.1_ Informational content _3.2_ Functional content _4_ Cases _4.1_ Case 1: Simplest case _4.2_ Case 2: Partial pooling _4.3_ Case 3: Bottleneck _4.4_ Case 4: Partial common interest _4.5_ Case 5: Deception _4.6_ Case 6: A further problem arising from divergent interests _5_ Discussion Appendix.

Nicholas Rescher presents a critical reaction against two currently influential tendencies of thought. On the one hand, he rejects the facile relativism that pervades contemporary social and academic life. On the other hand, he opposes the rationalism inherent in neo-contractarian theory--both in the idealized communicative-contract version promoted in continental European political philosophy by J;urgen Habermas, and in the idealized social contract version of the theory of political justice promoted in the Anglo-American context by John Rawls. Against such tendencies, Rescher's (...) pluralist approach takes a more realistic and pragmatic line, eschewing the convenient recourse of idealization in cognitive and practical matters. Instead of a utopianism that looks to a uniquely perfect order that would prevail under ideal conditions, he advocates incremental improvements within the framework of arrangements that none of us will deem perfect but that all of us "can live with." Such an approach replaces the yearning for an unattainable consensus with the institution of pragmatic arrangements in which the community will acquiesce--not through agreeing on their optimality, but through a shared recognition among the dissonant parties that the available options are even worse.

Nietzsche's Ecce Homo was published posthumously in 1908, eight years after his death, and has been variously described ever since as useless, mad, or merely inscrutable. Against this backdrop, Nicholas D. More provides the first complete and compelling analysis of the work, and argues that this so-called autobiography is instead a satire. This form enables Nietzsche to belittle bad philosophy by comic means, attempt reconciliation with his painful past, review and unify his disparate works, insulate himself with humor from (...) the danger of 'looking into abysses', and establish wisdom as a special kind of 'good taste'. After showing how to read this much-maligned book, More argues that Ecce Homo presents the best example of Nietzsche making sense of his own intellectual life, and that its unique and complex parody of traditional philosophy makes a powerful case for reading Nietzsche as a philosophical satirist across his corpus.

"A complete and unified account of Plato's epistemology... scholarly, historically sensitive, and philosophically sophisticated. Above all it is sensible.... White's strength is that he places Plato's preoccupation in careful historical perspective, without belittling the intrinsic difficulties of the problems he tackled.... White's project is to find a continuous argument running through Plato's various attacks on epistemological problems. No summary can do justice to his remarkable success." --Ronald B. De Sousa, University of Toronto, in Phoenix.

A step by step, passage by passage analysis of the complete Republic. White shows how the argument of the book is articulated, the important interconnections among its elements, and the coherent and carefully developed train of though which motivates its complex philosophical reasoning. In his extensive introduction, White describes Plato's aims, introduces the argument, and discusses the major philosophical and ethical theories embodied in the Republic. He then summarizes each of its ten books and provides substantial explanatory and interpretive notes.

The Comprehensibility of the Universe puts forward a radically new conception of science. According to the orthodox conception, scientific theories are accepted and rejected impartially with respect to evidence, no permanent assumption being made about the world independently of the evidence. Nicholas Maxwell argues that this orthodox view is untenable. He urges that in its place a new orthodoxy is needed, which sees science as making a hierarchy of metaphysical assumptions about the comprehensibility and knowability of the universe, these (...) assumptions asserting less and less as one ascends the hierarchy. This view has significant implications: that it is part of scientific knowledge that the universe is physically comprehensible; that metaphysics and philosophy are central to scientific knowledge; that science possesses a rational, if fallible, method of discovery; that a new understanding of scientific method and rationality is required. Maxwell argues that this new conception makes possible a natural resolution of long-standing philosophical problems about science, regarding simplicity, induction, and progress. His goal is the reform not just of the philosophy of science but of science itself, and the healing of the rift between the two. (shrink)

This paper presents a new solution to the problems for orthodox decision theory posed by the Pasadena game and its relatives. I argue that a key question raised by consideration of these gambles is whether evaluative compositionality (as I term it) is a requirement of rationality: is the value that an ideally rational agent places on a gamble determined by the values that she places on its possible outcomes, together with their mode of composition into the gamble (i.e. the probabilities (...) assigned to them)? The paper first outlines a certain simple response to the Pasadena game and identifies two problems with this response, the second of which is that it leads to a wholesale violation of evaluative compositionality. I then argue that rationality does not require decision makers to factor in outcomes of arbitrarily low probability. A method for making decisions which flows from this basic idea is then developed, and it is shown that this decision method (Truncation) leads to a limited — as opposed to wholesale — violation of evaluative compositionality. The paper then argues that the truncation method yields solutions to the problems posed by the Pasadena game and its relatives that are both attractive in themselves and superior to those yielded by alternative proposals in the literature.

"Understanding Scientific Progress constitutes a potentially enormous and revolutionary advancement in philosophy of science. It deserves to be read and studied by everyone with any interest in or connection with physics or the theory of science. Maxwell cites the work of Hume, Kant, J.S. Mill, Ludwig Bolzmann, Pierre Duhem, Einstein, Henri Poincaré, C.S. Peirce, Whitehead, Russell, Carnap, A.J. Ayer, Karl Popper, Thomas Kuhn, Imre Lakatos, Paul Feyerabend, Nelson Goodman, Bas van Fraassen, and numerous others. He lauds Popper for advancing beyond (...) verificationism and Hume’s problem of induction, but faults both Kuhn and Popper for being unable to show that and how their work could lead nearer to the truth." —Dr. LLOYD EBY teaches philosophy at The George Washington University and The Catholic University of America, in Washington, DC "Maxwell's aim-oriented empiricism is in my opinion a very significant contribution to the philosophy of science. I hope that it will be widely discussed and debated." – ALAN SOKAL, Professor of Physics, New York University "Maxwell takes up the philosophical challenge of how natural science makes progress and provides a superb treatment of the problem in terms of the contrast between traditional conceptions and his own scientifically-informed theory—aim-oriented empiricism. This clear and rigorously-argued work deserves the attention of scientists and philosophers alike, especially those who believe that it is the accumulation of knowledge and technology that answers the question."—LEEMON McHENRY, California State University, Northridge "Maxwell has distilled the finest essence of the scientific enterprise. Science is about making the world a better place. Sometimes science loses its way. The future depends on scientists doing the right things for the right reasons. Maxwell's Aim-Oriented Empiricism is a map to put science back on the right track."—TIMOTHY McGETTIGAN, Professor of Sociology, Colorado State University - Pueblo "Maxwell has a great deal to offer with these important ideas, and deserves to be much more widely recognised than he is. Readers with a background in philosophy of science will appreciate the rigour and thoroughness of his argument, while more general readers will find his aim-oriented rationality a promising way forward in terms of a future sustainable and wise social order."—David Lorimer, Paradigm Explorer, 2017/2 "This is a book about the very core problems of the philosophy of science. The idea of replacing Standard Empiricism with Aim-Oriented Empiricism is understood by Maxwell as the key to the solution of these central problems. Maxwell handles his main tool masterfully, producing a fascinating and important reading to his colleagues in the field. However, Nicholas Maxwell is much more than just a philosopher of science. In the closing part of the book he lets the reader know about his deep concern and possible solutions of the biggest problems humanity is facing."—Professor PEETER MŰŰREPP, Tallinn University of Technology, Estonia “For many years, Maxwell has been arguing that fundamental philosophical problems about scientific progress, especially the problem of induction, cannot be solved granted standard empiricism (SE), a doctrine which, he thinks, most scientists and philosophers of science take for granted. A key tenet of SE is that no permanent thesis about the world can be accepted as a part of scientific knowledge independent of evidence. For a number of reasons, Maxwell argues, we need to adopt a rather different conception of science which he calls aim-oriented empiricism (AOE). This holds that we need to construe physics as accepting, as a part of theoretical scientific knowledge, a hierarchy of metaphysical theses about the comprehensibility and knowability of the universe, which become increasingly insubstantial as we go up the hierarchy. In his book “Understanding Scientific Progress: Aim-Oriented Empiricism”, Maxwell gives a concise and excellent illustration of this view and the arguments supporting it… Maxwell’s book is a potentially important contribution to our understanding of scientific progress and philosophy of science more generally. Maybe it is the time for scientists and philosophers to acknowledge that science has to make metaphysical assumptions concerning the knowability and comprehensibility of the universe. Fundamental philosophical problems about scientific progress, which cannot be solved granted SE, may be solved granted AOE.” Professor SHAN GAO, Shanxi University, China . (shrink)

Are bacteriophage T4 and the long-nosed elephant fish valuable in their own right? Nicholas Agar defends an affirmative answer to this question by arguing that anything living is intrinsically valuable. This claim challenges received ethical wisdom according to which only human beings are valuable in themselves. The resulting biocentric or life-centered morality forms the platform for an ethic of the environment. -/- Agar builds a bridge between the biological sciences and what he calls "folk" morality to arrive at a (...) workable environmental ethic and a new spectrum--a new hierarchy--of living organisms. The book overturns common-sense moral belief as well as centuries of philosophical speculation on the exclusive moral significance of humans. Spanning several fields, including philosophy of psychology, philosophy of science, and other areas of contemporary analytic philosophy, Agar analyzes and speaks to a wide array of historic and contemporary views, from Aristotle and Kant, to E. O. Wilson, Holmes Rolston II, and Baird Callicot. The result is a challenge to prevailing definitions of value and a call for a scientifically-informed appreciation of nature. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 40.3 (2006) 92-114 [Access article in PDF] A Global Art System: An Exploration of Current Literature on Visual Culture, and a Glimpse at the Universal Promethean Principle—with Unintended Oedipal Consequences Art Education 11-18: Meaning, Purpose And Direction, edited by Richard Hickman; New York, Continuum; 2nd edition, 2004; 176 pp. Global Visual Culture within a Global Art System I have harbored misgivings about the term (...) "visual culture" for several years. Having read Hickman's book with its collection of notable scholars in art and design education, those misgivings turned into qualified acceptance of "visual culture"—so long as it is understood as a global visual culture within a global art system. The ten chapters presented in Hickman's book clearly explore the notion of visual culture in the context of generating an expansive and appropriate canon of art distinctly relevant to our postmodern, multicultural, multidimensional classroom of multiple intelligences.1 And so, art and design education for the twenty-first century must perform three essential functions: one, it must color the classroom with signs of global human pictorial and textual expressions; two, it must attempt to comprehend an immeasurable universe through creative, scaled-down explorations of the phenomenal world all of humanity is subject to; and three, it must open up the Blakeian doors of perception,2 while remaining free of emotional, educational, social, political, or religious ideological bonds. In this light, Hickman's Art Education 11-18 (2004), is a must read for art and design educators currently bogged down in old curriculum, and a must read for educators who incorporate new pedagogical literature easily into their new curriculum. And I say must read because we are on the verge of a revolution in visual art history and education—immersed in it, struggling to make sense of our beloved classical canon of art, and struggling to come to grips with a strangely foreign, beautifully alien, semeiotic reality we call (vaguely) "visual culture." It is a visual culture and history from the north, east, and south. Not just from the west.Key innovative educational issues addressed in these chapters are (respectively) using the dynamic nature of art to expand the curricula (Richard Hickman); the collapse of cultural borders (Lesley Burgess and Nicholas [End Page 92] Addison); a balanced cultural history of the world (Colin Grigg); recognizing art and recognizing visual culture (Howard Hollands); a range of visual cultures and literacy (Darren Newbury); using computer technology as a pathway to a new art and visual culture (Andy Ash); critical study and analysis (Michele Tallack); hand-making as a universal link to nature and art (Rachel Mason); spirituality in the process of art creation (James Hall); and cross-cultural heritage toward a new canon of art (Hickman).I will review each chapter as it pertains to current literature exploring popular pedagogical terms like "visual culture," "postmodernism," "pluralism," and "radicalism" and (more importantly) as it fits into a global system of art and culture. In addition, I suggest another term ("cosmopolitanism"—to identify the viable gay and lesbian aesthetic and culture) not that they are necessarily different, but they are indeed relevant and operate from a fresh literary and historical perspective. Then, I will illustrate how a new, postmodern canon of art must be linked to global visual culture and art in order to expand the concept of visual culture. Thus, I see two tasks before me: the first task is to inventory the philosophy, pedagogy, and meanings within each of the ten chapters in Hickman's Art Education 11-18; and the second task is to integrate key pedagogical ideas highlighted in each chapter as a method of generating a meaningful, holistic, integrated direction for art and design education in the twenty-first century. Integrating Art and Design Education Art is a design process. All subject regimes, D. N. Perkins suggests, are a design process.3 This may seem too obvious now after all these years since the publication of Knowledge... (shrink)

Political exclusion on grounds of incapacity is the primary remaining source of exclusion from the franchise. It is appealed to by states and theorists alike to justify excluding young people and many people with cognitive disability from the franchise. Defenders of this exclusion claim that no wrong is done by this exclusion and that states gain some significant benefits from this restricting of the franchise. I have argued elsewhere that political exclusion as currently practiced in modern liberal democratic states in (...) fact causes significant harms, as it excludes some people who have the relevant capacity for political participation. Here, I argue that the exclusion of incapable actors prevents no significant harms to democratic outcomes, and that it confers no significant democratic benefits on the states practising this exclusion. As such, I argue that we ought to heavily modify and perhaps even abandon the capacity standard for political inclusion. (shrink)

Nicholas Rescher presents an original pragmatic defense of the issue of objectivity. Rescher employs reasoned argumentation in restoring objectivity to its place of prominence and utility within social and philosophical discourse. By tracing the source of objectivity back to the very core of rationality itself, Rescher locates objectivity's reason for being deep in our nature as rational animals. His project rehabilitates the case for objectivity by subjecting relativistic and negativistic thinking to close critical scrutiny, revealing the flaws and fallacies (...) at work in the deliberations of those who dismiss objectivity as obsolete and untenable. Rescher takes to task the cultural relativism of contemporary social science and social theory, as well as that of liberalistic political correctness and the postmodern aversion to the normative. In holding such relativistic thinking up to the light of rational argument, he demonstrates that a rejection of objectivity is in fact unreasonable. Rescher further reveals that a relativistic apathy to truth and rightness actually destroys, in effect, the very conception it presumably elucidates. (shrink)

The rapid developments in technologies -- especially computing and the advent of many 'smart' devices, as well as rapid and perpetual communication via the Internet -- has led to a frequently voiced view which Nicholas Agar describes as 'radical optimism'. Radical optimists claim that accelerating technical progress will soon end poverty, disease, and ignorance, and improve our happiness and well-being. Agar disputes the claim that technological progress will automatically produce great improvements in subjective well-being. He argues that radical optimism (...) 'assigns to technological progress an undeserved pre-eminence among all the goals pursued by our civilization'. Instead, Agar uses the most recent psychological studies about human perceptions of well-being to create a realistic model of the impact technology will have. Although he accepts that technological advance does produce benefits, he insists that these are significantly less than those proposed by the radical optimists, and aspects of such progress can also pose a threat to values such as social justice and our relationship with nature, while problems such as poverty cannot be understood in technological terms. He concludes by arguing that a more realistic assessment of the benefits that technological advance can bring will allow us to better manage its risks in future. (shrink)

The experience of having to suffer debilitating pain is far too common in the United States, and many patients continue to be inadequately treated by their doctors. Although many physicians freely admit that their pain management practices may have been somewhat lacking, many more express concern that the prescribing of heightened levels of opioid analgesics may result in closer regulatory scrutiny, criminal investigation, or even criminal prosecution.Although several researchers have examined the regulatory environment and the threat of sanction or harm (...) it poses to physicians and patients, few have examined the likelihood of investigation or prosecution stemming from the aggressive use of opioids in physician-directed pain management. Accordingly, in an effort to assess whether the fear of prosecution is realistic and, if so, what factors contribute to its likelihood, we surveyed chief prosecutors in four states about their knowledge, opinions, and attitudes concerning opioids and the prosecution of physicians stemming from the treatment of patients who were either terminally ill or suffering from chronic noncancer pain.

This paper examines how new evil demon problems could arise for our access to the internal world of our own minds. I start by arguing that the internalist/externalist debate in epistemology has been widely misconstrued---we need to reconfigure the debate in order to see how it can arise about our access to the internal world. I then argue for the coherence of scenarios of radical deception about our own minds, and I use them to defend a properly formulated internalist view (...) about our access to our minds. The overarching lesson is that general epistemology and the specialized epistemology of introspection need to talk---each has much to learn from each other. (shrink)

Concepts are our tools for thinking. They enable us to engage in explicit reasoning about things in the world. Like physical tools, they can be more or less good, given the ways we use them – more or less dependable for categorisation, learning, induction, action-planning, and so on. Do concept users appreciate, explicitly or implicitly, that concepts vary in dependability? Do they feel that some concepts are in some way defective? If so, we metacognize our concepts. One example that has (...) been studied is a person’s judgement about how well they have learnt a new category. There are many other forms that concept-metacognition could take. This paper offers a preliminary taxonomy of different forms of metacognition directed at concepts. It suggests that concept-metacognition may affect the way one concept from a range of candidates is selected for use, and the way a concept is relied on in reasoning. Concept-metacognition may also play a pivotal role in the social process of constructing concepts, in replacing the old and constructing the new tools for thinking. (shrink)

A step towards a theory of consciousness would be to characterise the effect of consciousness on information processing. One set of results suggests that the effect of consciousness is to interfere with computations that are optimally performed non-consciously. Another set of results suggests that conscious, system 2 processing is the home of norm-compliant computation. This is contrasted with system 1 processing, thought to be typically unconscious, which operates with useful but error-prone heuristics. -/- These results can be reconciled by separating (...) out two different distinctions: between conscious and non-conscious representations, on the one hand, and between automatic and deliberate processes, on the other. This pair of distinctions is used to illuminate some existing experimental results and to resolve the puzzle about whether consciousness helps or hinders accurate information processing. This way of resolving the puzzle shows the importance of another category, which we label ‘type 0 cognition’, characterised by automatic computational processes operating on non-conscious representations.

I have argued for a picture of decision theory centred on the principle of Rationally Negligible Probabilities. Isaacs argues against this picture on the grounds that it has an untenable implication.

I then examine whether the implication is really undesirable and conclude that it is not.

Metaphysical graphical structuralism is the view that at some fundamental level the world is a mathematical graph of nodes and edges. Randall Dipert has advanced a graphical structuralist theory of fundamental particulars and Alexander Bird has advanced a graphical structuralist theory of fundamental properties. David Oderberg has posed a powerful challenge to graphical structuralism: that it entails the absurd inexistence of the world or the absurd cessation of all change. In this paper I defend graphical structuralism. A sharper formulation, some (...) theorems about such structures, and careful attention to the interaction of metaphysical and mathematical features, shows that the absurdities depend on assumptions that are not essential to the view and brings to light a surprising fact about the necessary structure of fundamental properties.

:This paper argues that capitalist social relations do not presuppose wage-labour. The paper defends a functional definition of the capitalist relations of production, in terms of what Marx calls the ’subsumption of labour by capital’. I argue that there are at least four modes of subsumption, one transitional to and one transitional from the capitalist mode of production. Unlike the capitalist mode of production, capitalist relations of production are compatible with the absence of a labour market, and even with the (...) absence of workplace authority relations. The ambit of capitalist domination is therefore broader than typically thought. (shrink)

According to Fumerton in his "How Does Perception Justify Belief?", it is misleading or wrong to say that perception is a source of justification for beliefs about the external world. Moreover, reliability does not have an essential role to play here either. I agree, and I explain why in section 1, using novel considerations about evil demon scenarios in which we are radically deceived. According to Fumerton, when it comes to how sensations or experiences supply justification, they do not do (...) so on their own, and instead only do so only in conjunction with support for background beliefs about how the sensations or experiences are best explained. Here I disagree. In section 2, I first clarify the question of whether sensations or experiences provide justification on their own. I then respond to Fumerton’s arguments that use considerations about concept-possession and about how to close possible gaps between experience and truth. In section 3, I develop my main concern about his positive view, where that concern also brings out some of the merits of the view that experiences do justify beliefs about the external world on their own.
