It is widely believed that such old-fashioned questions have been rendered absurd by the materialism of modern empirical science, but some seemingly 'magical' properties of quantum mechanics have brought them back into serious discussion in some circles. I will examine the possibility of making miracles using well-established principles of quantum mechanics--in particular, the possibility that quantum theory allows for the most desirable ' miracle ' of all: immortality.

A survey of Kant's views on space, time, geometry and the synthetic nature of mathematics. I concentrate mostly on geometry, but comment briefly on the syntheticity of logic and arithmetic as well. I believe the view of many that Kant's system denied the possibility of non-Euclidean geometries is clearly mistaken, as Kant himself used a non-Euclidean geometry (spherical geometry, used in his day for navigational purposes) in order to explain his idea, which amounts to an anticipation of the later discovery (...) of the general concept of non- Euclidean geometries. Kant's view of geometry and arithmetic as synthetic was, I believe, essentially correct, in that geometry and arithmetic are both synthetic a priori if considered as branches of mathematics independent of the rest of mathematics. However, the view that somehow logic is analytic, while mathematics is synthetic for Kantian reasons, is mistaken. All three disciplines—logic, arithmetic and geometry—are synthetic as disciplines independent from one another. However, they have a common basis, recursion theory, which I prefer to identify with mathematics as a whole. As a result, I do not say, as is often considered to be the Kantian view, that mathematics is synthetic while logic is analytic. Rather, I prefer to say that mathematics is analytic, while logic is synthetic. This is perfectly consistent with Kant's system, since it was arithmetic and geometry individually that he argued were synthetic. What Kant called the analytic is recursion theory, which could be considered as a basic formulation of mathematics or logic—or better, both mathematics and logic could be recognized as essentially the same discipline. However, if "logic" is taken to mean "predicate logic", as is often the case in modern times, then it is mathematics that is closer to Kant's analytic, not logic. Such ambiguities, of course, can be avoided by simply associating Kant's analytic with recursion theory, and avoiding the controversies as to what counts as mathematics or logic.. (shrink)

While the essays on this web site, taken together, explain most of the essentials of my metaphysical system, some material is not covered, and the different essays take quite different approaches. The essays were mostly written for undergraduate and graduate courses in philosophy at the University of Toronto and York University. Thus, each essay is slanted to the issues that were addressed in whatever course it was written for. However, I hope soon to pull all this material together into a (...) cohesive, single work that will explain my system more fully and with more focus, which will serve as my Ph.D. dissertation. In the meantime this brief overview gives the broad picture of what my philosophical system is, and how the various essays on these pages are inter-related. For those who do not wish to read through this entire page, the Quantum Phenomenology essay is probably the one you should read if you only have time to read one, as it is the closest to being comprehensive.

Plato's theory of forms is developed and compared to the modern theory of recursion. I show how Plato's theory, as it applies to mathematical objects, is essentially a primitve version of modern recursion theory, which has all the essential elements of the ancient theory. However, Plato himself thought there was more than mathematics to his forms. He believed that form had a noncomposite, unanalyzable component. So, while recursion theory provides an adequate formalization of Plato's theory, it cannot be considered identical (...) to it. I argue--drawing from material in the "Meno," "Phaedo," and "Republic"--that Plato's arguments for noncomposite form are largely fallacious. Plato would, I believe, have taken the computational version developed here seriously, since mathematics was his primary source for clear examples of forms (one could argue that it was his only source short of dipping into mysticism). In fact, there is a long-standing oral tradition that Plato developed a more formal version of his theory in lecture notes for courses he taught at the Academy (the university he founded in Athens). Any such notes, if they existed at all, have been lost. But if such a formal version did exist, it is tantalizing to wonder to what extent Plato may have anticipated modern theoretical computer science and metamathematics. (shrink)

Wittgenstein's philosophies, from both the Tractatus and the Philosophical Investigations, are explained and developed. Wittgenstein uses a primitive version of recursion theory to develop his attempt at a purely logical metaphysics in the Tractatus. However, due to his implicit materialist assumptions, he could not make the system completely logical, and built in a mystical division of possible worlds into the true and the false. This incoherence eventually lead him to reject logic as a method for doing metaphysics, and indeed to (...) reject metaphysics entirely. I argue that his move from the Tractatus to the Investigations was valid, but only given his materialist assumptions. If he had been willing to drop this unnecessary baggage, recursion would have played a very different role in his system, since he would then have had no need to separate static objects from processes, which he saw as purely mental. F.H. Bradley developed such a nonmaterialist metaphysics in the nineteenth century, but was crippled by a mentalism that Wittgenstein was free of. The anti-mentalism and anti-materialism that Wittgenstein considered as given were not so obvious to his predecessor, Russell, who revolted against Bradley's idealism in much the same way Wittgenstein ended up revolting against Russell's logical atomism. In my view, none of these positions was the right approach, which would require nonmentalism and nonmaterialism. But for some reason, these things (which seem to go together quite naturally to me) have been widely considered to be incompatible. Bradley was appropriately a non-materialist, but suffered from mentalism. Russell and the early Wittgenstein were appropriately nonmentalists, but suffered from materialism. The later Wittgenstein was, I would argue, still an ardent materialist and anti-mentalist, in spite of the fact that he had long since realized the contradictions to which materialism leads; he just had not recognized that it was his materialist assumptions that had lead him there, since these assumptions were so firmly engrained in his thinking as to be invisible..

A goal-oriented analysis of argument is presented based on Taylor's layered protocols, a theory of communication based on Powers' hierarchical perceptual control theory. Goals and beliefs are hierarchical, related in a precise way to sensory inputs an d motor outputs. This model is combined with Gilbert's theory of coalescent argumentation. Participants sketch out their own and their partner's goal diagrams as an aid to resolving the argument. For this to work, the argument must be viewed, not in pu rely linguistic (...) or logical terms, but in terms of the entire system of goals in which it is embedded. (shrink)

The many worlds anthropic principle is explored here from the a priori perspective of rationalist metaphysics, within the framework of modal logic. It is shown how the apparent contradictions of quantum superposition can be thought of in terms of different levels of world models. The framework of modal logic is used, but given the rationalist assumption that all possible worlds exist. There is thus no absolute distinction between possibility and necessity. To take the point of view of a conscious being (...) in a world, however, is to adopt some such distinction--something we must do in order to do physics. This paper is intended to lay the groundwork for future attempts to develop theories of what is necessarily true in a world with conscious entities. It also contains some tentative speculations on the difficult issue of death and quantum mechanics. (shrink)

The following is my interpretation of the philosophy of Parmenides of Elea , the Greek father of metaphysics. His only work, On Nature , is written in rather obscure verse, and so his thesis can be viewed from a variety of perspectives, of which mine is only one (although a fairly standard one). Parmenides' most important principle, hereafter called "Parmenides' Principle", was that anything rationally conceivable must exist. Nonbeing is not a thing and can neither be thought of nor spoken (...) about in any meaningful or coherent way. Parmenides forbade talking as if there are possible things that nonetheless do not exist. He illustrated this principle by showing us three possible methods of inquiry, of which only one is valid. The following chart summarizes them. (shrink)

Starting with the Descartes' cogito, "I think, therefore I am"--and taking an uncompromisingly rational, rigorously phenomenological approach--I attempt to derive the basic principles of recursion theory (the backbone of all mathematics and logic), and from that the principles of feedback control theory (the backbone of all biology), leading to the basic ideas of quantum mechanics (the backbone of all physics). What is derived is not the full quantum theory, but a basic framework--derived from a priori principles along with common everyday (...) experience--of how the universe of everyday experience should work if it operates according to rational principles. We find, to our surprise, that the resulting system has all the most puzzling features of quantum physics that make physicists scratch their heads. Far from being "bizarre" and "weird", as is usually thought, the strangest paradoxes of quantum theory turn out to be just what one ought to expect of a rational universe. It is the classical, pre-quantum universe of the nineteenth century that has irrational, mystical components. The quantum-mechanics-like theory that is developed is, furthermore, most compatible with the strictest, most uncompromisingly rationalist of the standard interpretations of quantum mechanics, those which add no ad hoc elements to the theory, and which generally trace their history to the relative state formulation of Everett (also called the "many worlds" interpretation). These interpretations take the universe to be quite literally describable as a quantum wavefunction. As with any project this far-reaching in scope, I confess I have had to make some working assumptions along the way. I have attempted to isolate these, and clearly label them as points of possible future revision--they are marked in the text with an asterisk (*). (shrink)

Those who interpret quantum mechanics literally are forced to follow some variant of Everett's relative state formulation (or "many worlds" interpretation). It is generally assumed that this is a rather bizarre result that many physicists (especially cosmologists) have been forced into because of the evidence. I look at the history of philosophy, however, reveals that rationalism has always flirted with this very idea, from Parmenides to Leibniz to modern times. I will survey some of the philosophical history, and show how (...) the so-called paradox of quantum superposition can be considered a consequence of basic rationalist assumptions such as the principle of sufficient reason and the identity of indiscernibles.

An overview of Bradley's metaphysics and epistemology, which had much of the basic structure of quantum mechanics, but was all but ignored in the years following the formal quantum theories discovered by Heisenberg and Schrödinger. Bradley's version of absolute idealism was infected with the mentalism that was generally associated with idealism in the late nineteenth century. I develop his ideas from a standpoint somewhat more friendly to modern formal methods, although this is not much of a stretch, as Bradley had (...) already taken absolute idealism strongly in that direction, if not all the way.

Joel Katzav's survey of the philosophy of Grace Andrus de Laguna's philosophy covers a broad range of ideas, and I have selected three for further development and commentary: (1) the relationship between naturalism and analytic philosophy, (2) the relationship between classical and radical empiricism, and (3) the historical question of where to situate a view such as de Laguna's in the history, the present, and the future of philosophy. I suggest that the view belongs with a group I call the (...) ‘New Naturalists’, including Theodore de Laguna, Susanne Langer, Marjorie Grene, Michael Polanyi, and others who keep philosophy closer to developments in natural and social science than is typical for pragmatists, process philosophers, and analytic philosophers. This is a position somewhere between classical and radical empiricism, but which insists that reductionism is too limiting and unwise, even when restricted to being only a method. (shrink)

There is, I shall assume, such a thing as moral evil (more on which below). My question is whether is also such a thing as non-moral evil, and in particular whether there are such things as aesthetic evil and epistemic evil. More exactly, my question is whether there is such a thing as moral evil but not such a thing as non-moral evil, in some sense that reveals something special about the moral, as opposed to such would-be non-moral domains as (...) the aesthetic and the epistemic. The philosophical issue at stake here is that of the nature of these different normative domains, and the nature and extent of their difference. (shrink)

Can understanding be transmitted by testimony, in the same sense that propositional knowledge can be transmitted by testimony? Some contemporary philosophers – call them testimonial understanding pessimists – say No, and others – call them testimonial understanding optimists – say Yes. In this chapter I will articulate testimonial understanding pessimism (§1) and consider some arguments for it (§2).

More has been said about the Hart-Fuller debate than can be considered healthy or productive even within the precious world of jurisprudential scholarship – too much philosophising about how law has revelled in its own abstractness and narrowness. But the mission of this book is distinctly and determinedly different – it is not to rework these already-rehashed ideas, but to reject them entirely. Rather than add to the massive jurisprudential literature that has been generated by all and sundry, the book (...) criticises and abandons the project that Hart and Fuller set in motion. It contends that the turn that was taken in 1957 has led down a series of cul-de-sacs, blind alleys, and dead-ends to nowhere useful or illuminating. It is more than past time to leave their debate behind and strike out in an entirely new and more promising direction. The book insists that not only law, but also all theorising about law, is political in all its derivations, dimensions, and directions. (shrink)

This book provides the reader with a detailed and captivating account of the story where, for the first time, physicists ventured into proposing a new force of nature beyond the four known ones - the electromagnetic, weak and strong forces, and gravitation - based entirely on the reanalysis of existing experimental data. Back in 1986, Ephraim Fischbach, Sam Aronson, Carrick Talmadge and their collaborators proposed a modification of Newton's Law of universal gravitation. Underlying this proposal were three tantalizing pieces of (...) evidence: 1) an energy dependence of the CP (particle-antiparticle and reflection symmetry) parameters, 2) differences between the measurements of G, the universal gravitational constant, in laboratories and in mineshafts, and 3) a reanalysis of the Eötvos experiment, which had previously been used to show that the gravitational mass of an object and its inertia mass were equal to approximately one part in a billion. The reanalysis revealed that, contrary to Galileo's position, the force of gravity was in fact very slightly different for different substances. The resulting Fifth Force hypothesis included this composition dependence and also added a small distance dependence to the inverse-square gravitational force. Over the next four years numerous experiments were performed to test the hypothesis. By 1990 there was overwhelming evidence that the Fifth Force, as initially proposed, did not exist. This book discusses how the Fifth Force hypothesis came to be proposed and how it went on to become a showcase of discovery, pursuit and justification in modern physics, prior to its demise. In this new and significantly expanded edition, the material from the first edition is complemented by two essays, one containing Fischbach's personal reminiscences of the proposal, and a second on the ongoing history and impact of the Fifth Force hypothesis from 1990 to the present. <.

Josiah Royce (1855?-1916) has had a major influence on American intellectual life, both popular movements and cutting-edge thought, but his name often went unmentioned while his ideas marched forward. The leading American proponent of absolute idealism, Royce has come back into fashion in recent years. With several important new books appearing, the formation of a Josiah Royce Society, and the re-organization of the Royce papers at Harvard, the time is ripe for Time, Will, and Purpose. Randall Auxier delves into (...) the primary texts written by Royce. (shrink)

As far back as we know, there have been individuals incapacitated by memories that have filled them with sadness and remorse, fright and horror, or a sense of irreparable loss. Only recently, however, have people tormented with such recollections been diagnosed as suffering from "post-traumatic stress disorder." Here Allan Young traces this malady, particularly as it is suffered by Vietnam veterans, to its beginnings in the emergence of ideas about the unconscious mind and to earlier manifestations of traumatic memory (...) like shell shock or traumatic hysteria. In Young's view, PTSD is not a timeless or universal phenomenon newly discovered. Rather, it is a "harmony of illusions," a cultural product gradually put together by the practices, technologies, and narratives with which it is diagnosed, studied, and treated and by the various interests, institutions, and moral arguments mobilizing these efforts. This book is part history and part ethnography, and it includes a detailed account of everyday life in the treatment of Vietnam veterans with PTSD. To illustrate his points, Young presents a number of fascinating transcripts of the group therapy and diagnostic sessions that he observed firsthand over a period of two years. Through his comments and the transcripts themselves, the reader becomes familiar with the individual hospital personnel and clients and their struggle to make sense of life after a tragic war. One observes that everyone on the unit is heavily invested in the PTSD diagnosis: boundaries between therapist and patient are as unclear as were the distinctions between victim and victimizer in the jungles of Southeast Asia.

Jörn Rüsen is the preeminent German practitioner of "historics," or theory of historiography. Unlike his closest American counterpart, Hayden White, Rüsen places particular emphasis on the historical discipline. The emphasis is embodied in Rüsen's notion of the "disciplinary matrix" of historiography, which embraces five "factors": the cognitive interest of human beings in having an orientation in time; theories or "leading views" concerning the experiences of the past; empirical research methods; forms of representation; and the function of offering orientation to society. (...) Rüsen's account of the disciplinary matrix will remind some readers of the "hermeneutic circle." But Rüsen is far closer to Jürgen Habermas than to Martin Heidegger or Hans-Georg Gadamer, for, like Habermas, he emphasizes the authoritative role of universal rational science.The essay argues that Rüsen's notion of the disciplinary matrix is an important contribution to the understanding of historiography. Combined with his parallel conception of differing "paradigms" of historiography, it helps us to make sense of the history of historiography, and is useful for analyzing and commenting on present-day historiography. The essay also argues for a greater degree of pluralism than seems assumed in Rüsen's view. It suggests that in an age of diversity the rhetorical conception of "topic"--which provides questions to be asked rather than answers--is of special use, and it reinterprets Rüsen's disciplinary matrix in a topical direction. Rüsen rightly suggests that historics has a unifying function. The essay suggests that, given social diversity, only such reflective theory can unite the varied body of historiography. This is one of the reasons why historiographical theory is important now. (shrink)

The Handbook of Philosophy of Education is a comprehensive guide to the most important questions about education that are being addressed by philosophers today. Authored by an international team of distinguished philosophers, its thirty-five chapters address fundamental, timely, and controversial questions about educational aims, justice, policy, and practices. Section I (Fundamental Questions) addresses the aims of education, authority to educate, the roles of values and evidence in guiding educational choices, and fundamental questions about human cognition, learning, well-being, and identity. Section (...) II (Virtues of Mind and Character) is concerned with the educational formation of personal attributes that are often seen as essential to flourishing individuals and societies. This section includes chapters on the cultivation of intellectual and character virtues, the nature and formation of expertise, Stoic virtues, and intellectual vices. Section III (Education and Justice) addresses fundamental and emerging issues of educational justice, from equal educational opportunity, racial domination, and linguistic justice in education, to educational problems of mass migration, global educational justice, the education of working children around the world, and the costs of higher education and upward mobility. Section IV (Educational Practices) addresses controversial aspects of contemporary education - pedagogical, curricular, and managerial practices - that deserve careful examination. These include controversies surrounding free speech and instruction in controversial issues; anti-racist, sustainability, and sex education; and the unfulfilled promises and demoralizing impact of high-stakes accountability schemes. The format and jargon-free writing in this volume ensure that topics are interesting and accessible, helping facilitate the work of advanced students and professionals in Education. (shrink)

In the history of Western thought, Christian theology was once considered to be 'the Queen of Sciences'. Today it has been marginalised by a prevailing scepticism. Randal Rauser confronts the problem of developing a public voice for the theologian as engaged in true theological science while not compromising the commitment to the Christian community of faith. This book posits a viable account of theological rationality, justification, and knowledge that avoids the twin pitfalls of modern rationalism and postmodern irrationalism. Theology is (...) freshly understood as a rigorous and rational truth-seeking discipline that seeks theoretical understanding of divine reality. Throughout the modern era the predominant epistemological position has been classical foundationalism, a position now widely rejected by philosophers and theologians alike. Philosophers recognize that it fails to achieve a plausible account of rationality, justification or knowledge, while theologians recognize the extent to which classical foundationalist strictures have distorted Christian doctrine. In its place many philosophers and theologians alike have adopted a nonfoundationalist epistemology, which is in turn often associated with a problematic alethic and metaphysical antirealism. Engaging with the ideas of key thinkers from Descartes, Locke, and Kant, to Bruce Marshall and Alvin Plantinga, Rauser provides an accessible and provocative survey of the theological terrain of the modern - and postmodern - era, arguing in favour of a return to a moderate foundationalism.

The aim here is to implement intelligence in an engineered processing substrate – a machine mind, as it were. This solution is clearly related to work in artificial intelligence (AI) and shares many of its analytical requirements and synthesis goals, but the objective is unambiguously to make individual human minds independent of a single substrate. Brain–machine interfaces require adaptations for communication to be possible, emphasizing either the machine or the brain. Brain emulation on general‐purpose computers is convenient, because model functions (...) can be modified easily. Ultimately, a mature emulation demands a suitable computing substrate. Theoretical debates occasionally focus on the question of determinism and computation in the Von Neumann sense.

In this chapter, Ayn Rand's new concept of morality is contrasted with familiar concepts according to which morality is an imposition on an individual that demands that he forgo his own interests as a sacrifice, whether to other people or to God. This chapter explores Rand's view that man's life is the standard of value and looks at each value that John Galt describes as supreme and ruling and, then, at the range of other values that Rand thinks man's life. (...) In discussing the supreme and ruling values, the chapter considers the three virtues that correspond to them: rationality, productiveness, and pride. It also looks at the four remaining virtues Rand identifies such as independence, integrity, honesty, and justice. Rand's conception of justice and the facts it recognizes is powerfully illustrated in Atlas Shrugged. Finally, the chapter examines Rand's view of heroism, which is closely connected with her ethics.

520 "Allan Beever lays the foundation for a timely philosophical and empirical study of the nature of law with a detailed examination of the structure of evolving law through declaratory speech acts. This engaging book demonstrates both how law itself is achieved and also its ability to generate rights, duties, obligations, permissions and powers. Structured into three distinct parts - the philosophy of law and jurisprudence, the structure of the social word and the ontology of law, and the reconstruction (...) of the philosophy of law - the author provides insight into law as a human institution and reveals that central debates are often based on misunderstandings of interpretation and intentionality. Inspired by the philosophy of John Searle alongside other well-respected legal theorists, the author also analyses both sides of the mainstream jurisprudential divide in its current state, in particular the theory of legal positivism. Examining all aspects of law and answering the important question of 'What is Law?', this book will be an invaluable resource for academics and advanced students in law schools and philosophy departments.

Aquinas talks about a topic with which fans of Sons of Anarchy are all too familiar: homicide and murder. For Aquinas, murder is the private, intentional homicide of an innocent human being and always wrong. This is called the Murder Principle. Murder is the killing of an innocent. This seems to leave the Sons—a private organization rather than an arm of the state—without the legitimate authority to take a life. Watching Sons of Anarchy makes us increasingly suspicious of the moral (...) authority of the state and its agents, who hardly seem like the competent “doctors” of Aquinas's amputation analogy. Contemporary philosophers have articulated the Doctrine of Double Effect (DDE), the gist of which states that it is sometimes morally permissible to bring about as a foreseen but unintended side‐effect what one would not be permitted to bring about intentionally. Aquinas's Murder Principle condemns much of what the Sons do. (shrink)

A number of scholars have suggested that Milgram’s laboratory studies of obedience offer an incisive analysis of the behavior of the Holocaust perpetrators. The present paper rejects that position. The contrasts between the two events, at every level of analysis, are striking: In Milgram’s research, innocent peers were harmed in the context of science; in the Holocaust, rabidly hated, subhuman enemies were murdered in the context of ‘war’. With regard to underlying psychological mechanisms, the evidence questioning the relevance of Milgram’s (...) research is equally compelling: obedience pressures had little role in the Holocaust. Most of the Nazi perpetrators showed no remorse or moral distress over the murders and perhaps most critically, virtually all of the killers knew that they could choose not to participate in the killings.
