As more criminals are imprisoned, other individuals change their behavior to replace them, as predicted by the theory of strategic behavior. The physiological correlates of sociopathy suggest that research in cognitive neuroscience can lead toward a solution. Promising pathways include building upon current knowledge of self-deceit, the independence of positive and negative emotions, the lateralization of risk and caution, and the conditions promoting prosocial behavior.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. The first volume covers the beginnings of a career that is ground-breaking from the outset. Inspired by courses given by Dirac and Bondi, much of the early (...) published work involves linking general relativity with tensor systems. Among his early works is the seminal 1955 paper, 'A Generalized Inverse for Matrices', his previously unpublished PhD and St John's College Fellowship theses, and from 1967, his Adam's Prize-winning essay on the structure of space-time. Add to this his 1965 paper, 'Gravitational collapse and space-time singularities', and the 1967 paper that introduced a remarkable new theory, 'Twistor algebra', and this becomes a truly stellar procession of works on mathematics and cosmology.

Professor Sir Roger Penrose is one of the truly original thinkers of our time. He has made several remarkable contributions to science, from quantum physics and theories of human consciousness to relativity theory and observations on the structure of the universe. Unusually for a scientist, some of his ideas have crossed over into the public arena. Now his work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for (...) the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. (shrink)
Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Many important realizations concerning twistor theory occurred during the short period of this third volume, providing a new perspective on the way that mathematical features of the (...) complex geometry of twistor theory relate to actual physical fields. Following on from the nonlinear graviton construction, a twistor construction was found for (anti-)self-dual electromagnetism allowing the general (anti-)self-dual Yang-Mills field to be obtained. It became clear that some features of twistor contour integrals could be understood in terms of holomorphic sheaf cohomology. During this period, the Oxford research group founded the informal publication, Twistor Newsletter. This volume also contains the influential Weyl curvature hypothesis and new forms of Penrose tiles.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Among the new developments that occurred during this period was the introduction of a particular notion of 'quasi-local mass-momentum and angular momentum', the topic of Penrose's Royal (...) Society paper. Many encouraging results were initially obtained but, later, difficulties began to emerge and remain today. Also, an extensive paper (with Eastwood and Wells) gives a thorough account of the relation between twistor cohomology and massless fields. This volume witnesses Penrose's increasing conviction that the puzzling issue of quantum measurement could only be resolved by the appropriate unification of quantum mechanics with general relativity, where that union must involve an actual change in the rules of quantum mechanics as well as in space-time structure. Penrose's first incursions into a possible relation between consciousness and quantum state reduction are also covered here. (shrink)
Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Publication of The Emperor's New Mind (OUP 1989) had caused considerable debate and Penrose's responses are included in this volume. Arising from this came the idea that (...) large-scale quantum coherence might exist within the conscious brain, and actual conscious experience would be associated with a reduction of the quantum state. Within this collection, Penrose also proposes that a twistor might usefully be regarded as a source (or 'charge') for a massless field of spin 3/2, suggesting that the twistor space for a Ricci-flat space-time might actually be the space of such possible sources. Towards the end of the volume, Penrose begins to develop a quite different approach to incorporating full general relativity into twistor theory. This period also sees the origin of the Diósi-Penrose proposal. (shrink)
Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. This sixth volume describes an actual experiment to measure the length of time that a quantum superposition might last (developing the Diósi-Penrose proposal). It also discusses the (...) significant progress made in relation to incorporating the 'googly' information for a gravitational field into the structure of a curved twistor space. Penrose also covers such things as the geometry of light rays in relation to twistor-space structures, the utility of complex numbers in drawing three-dimensional shapes, and the geometrical representation of different types of musical scales. The turn of the millennium was also an opportunity to reflect on progress in many areas up until that point. (shrink)
Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Developing ideas sketched in the first volume, twistor theory is now applied to genuine issues of physics, and there are the beginnings of twistor diagram theory (an (...) analogue of Feynman Diagrams). This collection includes joint papers with Stephen Hawking, and uncovers certain properties of black holes. The idea of cosmic censorship is also first proposed. Along completely different lines, the first methods of aperiodic tiling for the Euclidean plane that come to be known as Penrose tiles are described. This volume also contains Penrose's three prize-winning essays for the Gravity Foundation (two second places with both Ezra Newman and Steven Hawking, and a solo first place for 'The Non-linear graviton').

Roger North's The Musicall Grammarian 1728 is a treatise on musical eloquence in all its branches. Of its five parts, I and II, on the orthoepy, orthography and syntax of music, constitute a grammar; III and IV, on the arts of invention and communication, form a rhetoric; and V, on etymology, consists of a history. Two substantial chapters of commentary introduce the text, which is edited here for the first time in its entirety: Jamie Kassler places his treatise within (...) the broader context not only of North's musical and non-musical writings but also their relation to the intellectual ferment of the seventeenth and eighteenth centuries and Mary Chan describes physical and textual aspects of the treatise as evidence for North's processes of thinking about musical thinking.

Speaking is so closely associated with making noises that such descriptions as ‘silent soliloquy’ and ‘soundless monologue’ have an air of paradox. Yet people frequently say things to themselves in such a way that not even a close observer has any reason to think they have done so. It is therefore tempting to suppose that on such occasions a sequence of surrogate speech sounds is produced in the person's head which he alone hears or introaudits, as if what distinguishes silent (...) inner speech from normal speech is that the word substitutes are conveniently hidden from all save their producer.

A compelling defense of the sacred by one of today's leading philosophers In The Soul of the World, renowned philosopher Roger Scruton defends the experience of the sacred against today's fashionable forms of atheism. He argues that our personal relationships, moral intuitions, and aesthetic judgments hint at a transcendent dimension that cannot be understood through the lens of science alone. To be fully alive—and to understand what we are—is to acknowledge the reality of sacred things. Rather than an argument (...) for the existence of God, or a defense of the truth of religion, the book is an extended reflection on why a sense of the sacred is essential to human life—and what the final loss of the sacred would mean. In short, the book addresses the most important question of modernity: what is left of our aspirations after science has delivered its verdict about what we are? Drawing on art, architecture, music, and literature, Scruton suggests that the highest forms of human experience and expression tell the story of our religious need, and of our quest for the being who might answer it, and that this search for the sacred endows the world with a soul. Evolution cannot explain our conception of the sacred; neuroscience is irrelevant to our interpersonal relationships, which provide a model for our posture toward God; and scientific understanding has nothing to say about the experience of beauty, which provides a God’s-eye perspective on reality. Ultimately, a world without the sacred would be a completely different world—one in which we humans are not truly at home. Yet despite the shrinking place for the sacred in today’s world, Scruton says, the paths to transcendence remain open. (shrink)
The categories of reason and faith are often contrasted. When reason gives out, we are told that we have to rely on faith. Such exhortations are made particularly in the context of religion. When for instance, we face some personal tragedy which may well seem inexplicable, we are told that faith can help us through it. Very often faith is referred to in a vacuum. Presumably faith in God is usually meant, but all too often God drops out of the (...) picture, and it seems that all we need is faith, not faith in anything or anyone, but just faith. We are thus encouraged to add what seems to be a magic ingredient to our lives, which can transform everything. Perhaps at the back of such thinking lies some Calvinist notion of the corrupt character of human reason. As a result it may seem that we cannot rely on our judgment, which is the product of the fallen and sinful nature of humanity. Instead we must depend on ‘faith’ which may, or may not, be given us by the grace of God. (shrink)
Katherin A. Rogers presents a new theory of free will, based on the thought of Anselm of Canterbury. We did not originally produce ourselves. Yet, according to Anselm, we can engage in self-creation, freely and responsibly forming our characters by choosing 'from ourselves' between open options. Anselm introduces a new, agent-causal libertarianism which is parsimonious in that, unlike other agent-causal theories, it does not appeal to any unique and mysterious powers to explain how the free agent chooses. After setting out (...) Anselm's original theory, Rogers defends and develops it by addressing a series of standard problems levelled against libertarianism. Finally, as a theory about self-creation, Anselmian Libertarianism must defend the tracing thesis, the claim that an agent can be responsible for character-determined choices, if he, himself, formed his character through earlier a se choices. Throughout, Rogers defends and exemplifies a new methodological suggestion: someone debating free will ought to make his background world view explicit. In the on-going debate over the possibility of human freedom and responsibility, Anselmian Libertarianism constitutes a new and plausible approach. (shrink)
There is a certain attitude which makes freedom the main business of political thought and civil liberty the aim of government. I shall use the word ‘liberalism’ to refer to this attitude, in the hope that established usage will condone my description. And I shall explore and criticize two aspects of liberal thought: first, the concept of freedom in which it is based; secondly, the attack upon what Mill called the ‘despotism of custom’. My conclusions will be tentative; but I (...) should like to suggest that, properly understood, freedom and custom may require each other. Moreover to describe them as opposites is to make it impossible to see how either could be valued by a rational being, or why any politician should concern himself with their support or propagation.

He who has seen everything empty itself is close to knowing what everything is filled with. Emptiness is probably the most important philosophical and religious concept of Mahayana Buddhism. Its precise meaning has been explained differently by different schools and in different Buddhist cultures, but almost all Mahāyāna Buddhists would agree with the following characterization: Philosophically , emptiness is the term that describes the ultimate mode of existence of all phenomena, namely, as naturally ‘empty’ of enduring substance, or self-existence : (...) rather than being independently self-originated, phenomena are dependently originated from causes and conditions. Emptiness, thus, explains how it is that phenomena change and interact as they do, how it is that the world goes on as it does. Religiously , emptiness is the single principle whose direct comprehension is the basis of liberation from samsāra, and ignorance of which, embodied in self-gasping is the basis of continued rebirth – hence suffering – in samsāra.

Human beings talk and co-operate, they build and produce, they work to accumulate and exchange, they form societies, laws and institutions, and, in all these things the phenomenon of reason—as a distinct principle of activity—seems dominant. There are indeed theories of the human which describe this or that activity as central—speech, say, productive labour, or political existence. But we feel that the persuasiveness of such theories depends upon whether the activity in question is an expression of the deeper essence, reason (...) itself, which all human behaviour displays.

Aristotle's Nicomachean Ethics, based on lectures that he gave in Athens in the fourth century BCE, is one of the most significant works in moral philosophy, and has profoundly influenced the whole course of subsequent philosophical endeavour. It is soundly located within a philosophical tradition, but its argument differs markedly from those of Plato and Socrates in its emphasis on the exercise - as opposed to the mere possession - of virtue as the key to human happiness, offering seminal discussions (...) of ethical issues that are practical in their intent. Topics covered include the role of luck in human wellbeing, moral education, responsibility, courage, justice, moral weakness, friendship and pleasure. This accessible new translation by Roger Crisp follows the Greek text closely and also provides a non-Greek-reader with the flavour of the original. The volume also includes a historical and philosophical introduction and notes on further reading. (shrink)
Homeostatic property clusters (HPCs) are offered as a way of understanding natural kinds, especially biological species. I review the HPC approach and then discuss an objection by Ereshefsky and Matthen, to the effect that an HPC qua cluster seems ill-fitted as a description of a polymorphic species. The standard response by champions of the HPC approach is to say that all members of a polymorphic species have things in common, namely dispositions or conditional properties. I argue that this response fails. (...) Instances of an HPC kind need not all be similar in their exhibited properties. Instead, HPCs should instead be understood as unified by the underlying causal mechanism that maintains them. The causal mechanism can both produce and explain some systematic differences between a kind’s members. An HPC kind is best understood not as a single cluster of properties maintained in stasis by causal forces, but as a complex of related property clusters kept in relation by an underlying causal process. This approach requires recognizing that taxonomic systems serve both explanatory and inductive purposes. (shrink)
From Thomas Hobbes to Jeremy Bentham, 'British Moralists' have questioned whether being virtuous makes you happy. Roger Crisp elucidaties their views on happiness and virtue, self-interest and sacrifice, and well-being and morality, and highlights key themes such as psychological egoism, evaluative hedonism, and moral reason in their thought.
A generation of students at the Faculty of Theology of the K.U.Leuven have been introduced by Roger Burggraeve to the thoughts of Emmanuel Levinas. Levinas has been for him a true "master in thinking". For Levinas responsibility is heteronymous because it does not start from the "I" but from the epiphany of the other as the face, appealing to me not "to kill" but to promote him/her. In and through the appeal of the face, the difference between the other (...) and me - expressed in the irreducible alterity of the other - is, ethically speaking, the appeal to the highest "non-indifference": proximity without absorption. As Levinas' thinking carries on obvious Jewish-Talmudic imprint, Burggraeve was interested as to how the concept of responsibility can be connected to a biblically inspired ethic. In which way can the Levinasian view on responsibility enhance a Christian anthropology, and in particular that one articulated by Louvain personalism, and in its turn inspired by a Christian anthropology, so that it benefits from uniquely Christian accents? In this Festschrift for Roger Burggraeve, authors explore the theme of "Responsibility, God and Society" in order to answer two questions. What does Levinas' ethic of responsibility have to offer Christian theology? And vice-versa, what can Christian theology offer to contemporary ethical thought on personal, relational and societal responsibility. (shrink)
Roger Crisp presents a comprehensive study of Henry Sidgwick's The Methods of Ethics, a landmark work first published in 1874. Crisp argues that Sidgwick is largely right about many central issues in moral philosophy: the metaphysics and epistemology of ethics, consequentialism, hedonism about well-being, and the weight to be given to self-interest. He holds that Sidgwick's long discussion of 'common-sense' morality is probably the best discussion of deontology we have. And yet The Methods of Ethics can be hard to (...) understand, and this is perhaps one reason why, though it is a philosophical goldmine, few have ventured deeply into it. What does Sidgwick mean by a 'method'? Why does he discuss only three methods? What are his arguments for hedonism and for utilitarianism? How can we make sense of the idea of moral intuition? What is the role of virtue in Sidgwick's ethics? Crisp addresses these and many other questions, offering a fresh view of Sidgwick's text which will assist any moral philosopher to gain more from it.

Unlike some other reproductions of classic texts We have not used OCR, as this leads to bad quality books with introduced typos. In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
