The process of recognition or isolation of one or several entities from among many possible entities is termed intellego perception. It is shown that not only are many of our everyday percepts of this type, but perception of microscopic events using the methods of quantum mechanics are also intellego in nature. Information theory seems to be a natural language in which to express perceptual activity of this type. It is argued that the biological organism quantifies its sensations using an information (...) theoretical measure. This, in turn, sets the stage for a mathematical theory of sensory perception.

Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational theories (...) in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)

This edition includes a new introduction by Peter J. Gomes that reflects on the impact of this book in the years since it was written.

With reference to two specific modalities of sensation, the taste of saltiness of chloride salts, and the loudness of steady tones, it is shown that the laws of sensation (logarithmic and power laws) are expressions of the entropy per mole of the stimulus. That is, the laws of sensation are linear functions of molar entropy. In partial verification of this hypothesis, we are able to derive an approximate value for the gas constant, a fundamental physical constant, directly from psychophysical measurements. (...) The significance of our observation lies in the linking of the phenomenon of “sensation” directly to a physical measure. It suggests that if the laws of physics are universal, the laws of sensation and perception are similarly universal. It also connects the sensation of a simple, steady physical signal with the molecular structure of the signal: the greater the number of microstates or complexions of the stimulus signal, the greater the magnitude of the sensation (saltiness or loudness). The hypothesis is currently tested on two sensory modalities. (shrink)

The case is presented for a dilemmatic perspective to the educational provision for pupils and students with difficulties and disabilities. This perspective recognises the links and tensions between social and individual values and models. The paper focuses on the central significance of dilemmas of difference in understanding policy and practice issues in the field. One of the central arguments is that a commitment to inclusion implies a commitment to meeting the needs of a minority and therefore to arrangements which may (...) not be required by the majority. Inclusion is about mainstream schools accommodating a full diversity, and in doing so leads inevitably to adopting dedicated or specialised support systems for some. The paper provides an overview of recent changes in policy and practice as well as looking at possible future trends. An inter-disciplinary model which connects individual and social perspectives is proposed both for explanatory purposes and for designing provision in terms of the interaction between the inclusivity of the system and responding to additional individual needs.

This paper reports on part of an evaluation of teacher support teams as a special education needs support strategy in primary schools. Using a mixture of quantitative and qualitative evaluation methods, it focuses on areas derived from a theoretical framework for understanding schools’ approaches to SENs. TSTs were set up and run in six of the eight schools, with meetings of between 30 and 45 minutes, usually during lunchtime or after school. Most of the referrals were about behaviour problems, though (...) many were about learning difficulties. The support included providing emotional encouragement, specific approaches to managing behaviour, teaching strategies and consulting others. Referring teachers reported that their TST experience led to increased confidence and some improvements in the children, while TST members themselves believed that they had gained much from the TST experience. Overall the study showed the feasibility and benefits of setting up TSTs in primary schools. The findings are discussed in terms of the wider benefits of TSTs and their relevance to special needs policies and the implementation of the SENs code of practice. (shrink)

In this chapter a new problem about rule-following is outlined, one that is distinct both from Kripke’s and Wright’s versions of the problem. This new problem cannot be correctly responsed to, as Kripke’s can, by invoking Wright’s Intentional Account of rule-following. The upshot might be called, following Kant, an antinomy of pure reason: we both must — and cannot — make sense of someone’s following a rule. The chapter explores various ways out of this antinomy without here endorsing any of (...) them. (shrink)

This is a collection in translation of essays by Paul Ricoeur which presents a comprehensive view of his philosophical hermeneutics, its relation to the views of his predecessors in the tradition and its consequences for the social sciences. The volume has three parts. The studies in the first part examine the history of hermeneutics, its central themes and the outstanding issues it has to confront. In Part II, Ricoeur's own current, constructive position is developed. A concept of the text (...) is formulated as the implications of the theory are pursued into the domains of sociology, psychoanalysis and history. Many of the essays appear here in English for the first time; the editor's introduction brings out their background in Ricoeur's thought and the continuity of his concerns. The volume will be of great importance for those interested in hermeneutics and Ricoeur's contribution to it, and will demonstrate how much his approach offers to a number of disciplines. (shrink)

Paul Thom's book presents Kilwardby's science of logic as a body of demonstrative knowledge about inferences and their validity, about the semantics of non-modal and modal propositions, and about the logic of genus and species. This science is thoroughly intensional. It grounds the logic of inference on "that in virtue of which" the inference holds. It bases the truth conditions of propositions on relations between conceptual entities. It explains the logic of genus and species through the notion of essence. (...) Thom interprets this science as a formal logic of intensions with its own proof theory and semantics. This comprehensive reconstruction of Kilwardby's logic shows the medieval master to be one of the most interesting logicians of the thirteenth century. (shrink)

De milieuproblematiek staat pas sinds kort op de agenda als een fenomeen dat de mensheid bedreigt. Toch blijkt het negentiende-eeuwse gedachtegoed van Karl Marx verrassende inzichten te bieden om deze actuele problemen te duiden. Marx laat zien dat het menselijk ingrijpen in de natuur leidt tot zelfvervreemding: de mens ondermijnt zijn bestaan als een wezen dat zelf deel uitmaakt van de natuur. Deze zelfvervreemding cumuleert in de kapitalistische samenleving. Marx lezend zien we dat de milieuproblematiek geen historische vergissing is, maar (...) fundamenteel samenhangt met de mens als redelijk wezen. Onze beheersingsrede heeft geleid tot de vervreemding van de natuur. Toch geeft dezelfde rede die de mens de vrijheid biedt zich boven het ecologische evenwicht te verheffen, hem de mogelijkheid zich te verzoenen met de natuur. Marx verwijst naar dit dubbele gezicht van de rede als hij stelt dat het 'rijk van de vrijheid' in de schoot van het kapitalisme wordt geboren. In dit boek onderzoekt Paul Cobben welke aanzetten de huidige samenleving biedt om vorm te geven aan de verzoening met de natuur. Paul Cobben is emeritus hoogleraar geschiedenis van de moderne filosofie aan Tilburg University. Momenteel is hij gastonderzoeker aan de Vrije Universiteit Amsterdam en redacteur van de serie 'Critical Studies in German Idealism'. Van zijn hand verscheen o.a. 'Value in Capitalist Society. Rethinking Marx's Criticism of Capitalism' (2015)."-- Publisher information. (shrink)

The Renaissance was a period of great intellectual change and innovation as philosophers rediscovered the philosophy of classical antiquity and passed it on to the modern age. Renaissance philosophy is distinct both from the medieval scholasticism, based on revelation and authority, and from philosophers of the seventeenth and eighteenth centuries who transformed it into new philosophical systems. Despite the importance of the Renaissance to the development of philosophy over time, it has remained largely understudied by historians of philosophy and professional (...) philosophers. This anthology aims to correct this by providing scholars and students of philosophy with representative translations of the most important philosophers of the Renaissance. Its purpose is to help readers appreciate philosophy in the Renaissance and its importance in the history of philosophy. The anthology includes translations from philosophers from the thirteenth to the seventeenth centuries, and it ranges from works on moral and political philosophy, to metaphysics, epistemology, and natural philosophy, thereby providing historians and students of philosophy with a sense for the nature, breadth, and complexity of philosophy in the Renaissance. Each translation is accompanied by an introduction by a historian of Renaissance philosophy, as well as select secondary sources, in order to encourage further study. (shrink)

Paul Helm investigates what religious faith is and what makes it reasonable.

Logic brings elementary logic out of the academic darkness into the light of day. Paul Tomassi makes logic fully accessible for anyone trying to come to grips with the complexities of this challenging subject. This book is written in a patient and user-friendly way which makes both the nature and value of formal logic crystal clear. This textbook proceeds from a frank, informal introduction to fundamental logical notions to a system of formal logic rooted in the best of our (...) natural deductive reasoning in daily life. The book includes plenty of exercise to put the students' reading to test, summay boxes of key points, a glossary and many illustrations. This book will be useful to any student who needs a patient and comprehensible introduction to what otherwise can be a daunting subject. (shrink)

We sometimes strive to achieve difficult goals when our evidence suggests that success is unlikely – not just because it will require strength of will, but because we are targets of prejudice and discrimination or because success will require unusual ability. Optimism about one’s prospects can be useful for persevering in these cases. That said, excessive optimism can be dangerous; when our evidence is unfavourable, we should be at most agnostic about whether we will succeed. This paper explores the nature (...) and rational significance of agnostic practical commitments. Most importantly, the rationality of striving against the odds can depend on investing in a plan for failure: a plan B. I aim to make headway on an account of what backup plans are, how they are related to primary plans, and whether the standard norms of plan rationality apply to our agnostic commitments. (shrink)

We are witnessing increasing use of the Internet, particular social media, to criticize (perceived or actual) moral failings and misdemeanors. This phenomenon of so-called ‘online public shaming’ could provide a powerful tool for reinforcing valuable social norms. But it also threatens unwarranted and severe punishments meted out by online mobs. This paper analyses the dangers associated with the informal enforcement of norms, drawing on Locke, but also highlights its promise, drawing on recent discussions of social norms. We then consider two (...) crucial conditions that online public shaming must meet in order to be justifiable: proportionality and accountability. We argue that these requirements are in fact frequently violated, rendering most cases of online public shaming unjustified. While the use of online public shaming against others’ vices has some apparent virtues, it is currently rarely justified, given its own vices. (shrink)

The relationship between abstract formal procedures and the activities of actual physical systems has proved to be surprisingly subtle and controversial, and there are a number of competing accounts of when a physical system can be properly said to implement a mathematical formalism and hence perform a computation. I defend an account wherein computational descriptions of physical systems are high-level normative interpretations motivated by our pragmatic concerns. Furthermore, the criteria of utility and success vary according to our diverse purposes and (...) pragmatic goals. Hence there is no independent or uniform fact to the matter, and I advance the ‘anti-realist’ conclusion that computational descriptions of physical systems are not founded upon deep ontological distinctions, but rather upon interest-relative human conventions. Hence physical computation is a ‘conventional’ rather than a ‘natural’ kind. (shrink)

This paper introduces constitutivism about practical reason, which is the view that we can justify certain normative claims by showing that agents become committed to these claims simply in virtue of acting. According to this view, action has a certain structural feature – a constitutive aim, principle, or standard – that both constitutes events as actions and generates a standard of assessment for action. We can use this standard of assessment to derive normative claims. In short, the authority of certain (...) normative claims arises from the bare fact that we are agents. This essay explains the constitutivst strategy, surveys the extant attempts to generate constitutivist theories, and considers the problems and prospects for the theory. (shrink)

In this book, Russell examines Hume's notion of free will and moral responsibility. It is widely held that Hume presents us with a classic statement of a compatibilist position--that freedom and responsibility can be reconciled with causation and, indeed, actually require it. Russell argues that this is a distortion of Hume's view, because it overlooks the crucial role of moral sentiment in Hume's picture of human nature. Hume was concerned to describe the regular mechanisms which generate moral sentiments such as (...) responsibility, and Russell argues that his conception of free will must be interprted within this naturalistic framework. He goes on to discuss Hume's views about the nature and character of moral sentiment; the extent to which we have control over our moral character; and the justification of punishment. Throughout, Russell argues that the naturalistic avenue of interpretation of Hume's thought, far from draining it of its contemporary interest and significance, reveals it to be of great relevance to the ongoing contemporary debate - particuarly in relation to the views of P.F. Strawson and his influential paper "Freedom and Resentment". (shrink)

Reasons and reasoning were central to the work of Paul Grice, one of the most influential and admired philosophers of the late twentieth century. In the John Locke Lectures that Grice delivered in Oxford at the end of the 1970s, he set out his fundamental thoughts about these topics; Aspects of Reason is the long-awaited publication of those lectures. This immensely rich work, powerfully evocative of the mind of its author, will refresh and illuminate discussions in many areas of (...) contemporary philosophy. (shrink)

The Oxford Handbook of Epistemology contains 19 previously unpublished chapters by today's leading figures in the field. These chapters function not only as a survey of key areas, but as original scholarship on a range of vital topics. Written accessibly for advanced undergraduates, graduate students, and professional philosophers, the Handbook explains the main ideas and problems of contemporary epistemology while avoiding overly technical detail.

Freud claimed that the concept of drive is "at once the most important and the most obscure element of psychological research." It is hard to think of a better proof of Freud's claim than the work of Nietzsche, which provides ample support for the idea that the drive concept is both tremendously important and terribly obscure. Although Nietzsche's accounts of agency and value everywhere appeal to drives, the concept has not been adequately explicated. I remedy this situation by providing an (...) account of drives. I argue that Nietzschean drives are dispositions that generate evaluative orientations, in part by affecting perceptual saliences. In addition, I show that drive psychology has important implications for contemporary accounts of reflective agency. Contemporary philosophers often endorse a claim that has its origins in Locke and Kant: self-conscious agents are capable of reflecting on and thereby achieving a distance from their motives; therefore, these motives do not determine what the agent will do. Nietzsche's drive psychology shows that the inference in the preceding sentence is illegitimate. The drive psychology articulates a way in which motives can determine the agent's action by influencing the course of the agent's reflective deliberations. An agent who reflects on a motive and decides whether to act on it may, all the while, be surreptitiously guided by the very motive upon which he is reflecting. I show how this point complicates traditional models of the role of reflection in agency. (shrink)

[Significantly updated in Chapter 6 of Awareness and the Substructure of Knowledge] In order for a reason to justify an action or attitude it must be one that is possessed by an agent. Knowledge-centric views of possession ground our possession of reasons, at least partially, either in our knowledge of them or in our being in a position to know them. On virtually all accounts, knowing P is some kind of non-accidental true belief that P. This entails that knowing P (...) is a kind of non-accidental true representation that P. I outline a novel theory of the epistemic requirement on possession in terms of this more general state of non-accidental true representation. It is just as well placed to explain the motivations behind knowledge-centric views of possession, and it is also better placed to explain the extent of the reasons we possess in certain cases of deductive belief-updates and cases involving environmental luck. I conclude with three reflections. First, I indicate how my arguments generate a dilemma for Errol Lord’s view that possessing reasons is just a matter of being in a position to manifest one’s knowledge how to use them. Second, I explain how my view can simultaneously manage cases of environmental luck without falling prey to lottery cases. Finally, I sketch the direction for a further range of counterexamples to knowledge-centric theories of possession. (shrink)

"Evidence of a flight from reason is as old as human record-keeping: the fact of it certainly goes back an even longer way. Flight from science specifically, among the forms of rational inquiry, goes back as far as science itself... But rejection of reason is now a pattern to be found in most branches of scholarship and in all the learned professions."--from the introduction In the widely acclaimed Higher Superstition: The Academic Left and Its Quarrels with Science, Paul R. (...) Gross and Norman Levitt offered a spirited response to the "science bashers," raising serious questions about the growing criticism of scientific practice from humanists and social scientists on the academic left. Now, in The Flight from Science and Reason, Gross and Levitt are joined by Martin W. Lewis to bring together a diverse and distinguished group of scholars, scientists, and experts to engage these questions from a wide variety of perspectives. The authors take on critics of science whose views range from moderate to extreme, from social constructivists to deconstructionists, from creationists and feminists to Afro-centrists. They discuss the rise of "alternative medicine" and radical environmentalism (here skewered as "ecosentimentalism"). They explain why the "uncertainty principle" does not work as a metaphor for ambiguity, and why "chaos theory" cannot be invoked without an understanding of mathematics. Throughout, they grapple with the paradox inherent in arguing with opponents who contend that reason itself, and thus logic, is suspect. Distributed for the New York Academy of Sciences. (shrink)

Conservatism about perceptual justification tells us that we cannot have perceptual justification to believe p unless we also have justification to believe that perceptual experiences are reliable. There are many ways to maintain this thesis, ways that have not been sufficiently appreciated. Most of these ways lead to at least one of two problems. The first is an over-intellectualization problem, whereas the second problem concerns the satisfaction of the epistemic basing requirement on justified belief. I argue that there is at (...) least one Conservative view that survives both difficulties, a view which has the further ability to undercut a crucial consideration that has supported Dogmatist views about perceptual justification. The final section explores a tension between Conservatism and the prospects of having a completely general account of propositional justification. Ironically, the problem is that Conservatives seem committed to making the acquisition of propositional justification too easy. My partial defense of Conservatism concludes by suggesting possible solutions to this problem. (shrink)

Vorrangig als der "strengste Methodenfanatiker und Logizist" der Marburger Schule des Neukantianismus bekannt, trat Natorp jedoch genau an diesem Punkt mit der selbständigen Form seines späten Philosophierens hervor: der Überschreitung der Methode in der Idee einer allgemeinen Logik. Unter allgemeiner Logik versteht er die streng einheitliche logische Grundlegung der Gegenstandssetzung, ja aller irgendwie logisch erfaßlichen Setzung. Damit war ein Zugang geschaffen zu der von Natorp angestrebten Erkenntnis des Geistigen in seiner Ureinheit, aus der erst die Besonderungen hervorgehen.

The ethical issues raised by cybersecurity practices and technologies are of critical importance. However, there is disagreement about what is the best ethical framework for understanding those issues. In this paper we seek to address this shortcoming through the introduction of a principlist ethical framework for cybersecurity that builds on existing work in adjacent fields of applied ethics, bioethics, and AI ethics. By redeploying the AI4People framework, we develop a domain-relevant specification of five ethical principles in cybersecurity: beneficence, non-maleficence, autonomy, (...) justice, and explicability. We then illustrate the advantages of this principlist framework by examining the ethical issues raised by four common cybersecurity contexts: penetration testing, distributed denial of service attacks (DDoS), ransomware, and system administration. These case analyses demonstrate the utility of this principlist framework as a basis for understanding cybersecurity ethics and for cultivating the ethical expertise and ethical sensitivity of cybersecurity professionals and other stakeholders.

When we define something as a crime, we generally thereby criminalize the attempt to commit that crime. However, it is a vexing puzzle to specify what must be the case in order for a criminal attempt to have occurred, given that the results element of the crime fails to come about. I argue that the philosophy of action can assist the criminal law in clarifying what kinds of events are properly categorized as criminal attempts. A natural thought is that this (...) project should take the form of specifying what it is in general to attempt or try to perform an action, and then to define criminal attempts as attempts to commit crimes. Focusing on Gideon Yaffe's resourceful work in Attempts (Oxford University Press, 2010) as an example of this strategy, I argue that it results in a view that is overly inclusive: one will count as trying to commit a crime even in the far remote preparatory stages that we in fact have good reason not to criminalize. I offer an alternative proposal to distinguish between mere preparations and genuine attempts that has its basis not in trying, but doing: a criminal attempt is underway once what the agent is doing is a crime. Working out the details of this schema turns out to have important implications for action theory. A recently burgeoning view known as Naive Action Theory holds that all action can be explained by appeal to some further thing that the agent is doing, and that that the same explanatory nexus is at work even when we appeal to what the agent is intending, trying, or preparing to do -- these notions do explanatory work because they too refer to actions that are in progress, albeit in their infancy. If this is right, than the notion of 'doing' will also be too inclusive for the purposes of the criminal law. I argue that we should draw the reverse conclusion: the distinctions between pure intending, trying, preparing, and doing serve an important purpose in the criminal law, and this fact lends support to the view that they are genuine metaphysical and explanatory distinctions.
