Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Aristotle's doctrine of the four causes--formal, final, efficient and material--is famous. But Posterior Analytics B 11 lists "if certain things hold, it is necessary that this does" in place of a standard expression for the material cause. This cause has been dubbed the grounding cause. It has interested scholars since the Greek commentators, who simply assumed that Aristotle meant the material cause. This traditional thesis has been challenged by two views: first, that the grounding cause is a special type of (...) material cause ; second, that it is no material cause at all . ;I set out two arguments for the traditional thesis and consider nine objections to it. Since most of these objections, which constitute the support for the revisionist thesis, can be answered, I reject the revisionist thesis. But in my treatment of one objection it also becomes clear that the traditional thesis is mistaken. The grounding cause is a necessitating cause, yet in Physics B 9 Aristotle makes it clear that many material causes are not necessitating causes. Thus, some form of the modified traditional thesis is true. ;But which form? D. M. Balme suggests that Aristotle means to include only mathematical causes because hypothetical necessity covers all of the relation between matter and product in things which come to be. But Aristotle seems to accept necessitating material causes in several passages in the biological works. In other passages he seems to adopt the position Balme attributes to him. I argue that he does not actually adopt this position, and that he does accept simple necessity in some things which come to be. Thus, the grounding cause is a necessitating material cause, and such causes are found not only in mathematics, but also among things which come to be. (shrink)

Based on the relevant logic R, the system R# was proposed as a relevant Peano arithmetic. R# has many nice properties: the most conspicuous theorems of classical Peano arithmetic PA are readily provable therein; it is readily and effectively shown to be nontrivial; it incorporates both intuitionist and classical proof methods. But it is shown here that R# is properly weaker than PA, in the sense that there is a strictly positive theorem QRF of PA which is unprovable in R#. (...) The reason is interesting: if PA is slightly weakened to a subtheory P+, it admits the complex ring C as a model; thus QRF is chosen to be a theorem of PA but false in C. Inasmuch as all strictly positive theorems of R# are already theorems of P+, this nonconservativity result shows that QRF is also a nontheorem of R#. As a consequence, Ackermann's rule γ is inadmissible in R#. Accordingly, an extension of R# which retains its good features is desired. The system R##, got by adding an omega-rule, is such an extension. Central question: is there an effectively axiomatizable system intermediate between R# and R##, which does formalize arithmetic on relevant principles, but also admits γ in a natural way? (shrink)

This paper predicts the probability of a profound world climate change that will affect the governance of the world's societies. Carbon dioxide levels in the earth's atmosphere may be doubled in sixty years, warming the earth's climate and altering drastically the patterns of food production, agriculture, forestry and consequently relations between societies.

In Aristotle's biological works, there is an apparent conflict between passages which seem to insist that only hypothetical necessity (anagk ex hypotheses) operates in the sublunary world, and passages in which some biological phenomena are explained as simply (hapls) necessary. Parallel to this textual problem lies the claim that explanations in terms of simple necessity render teleological explanations (in some of which Aristotle puts hypothetical necessity to use) superfluous. I argue that the textual conflict is only apparent, and that Aristotle's (...) notion of coincidental sameness allows him to avoid the superfluity problem. (shrink)

It has already been argued by Frazer and Boland (1983) that, interpreted in an instrumentalist fashion, Milton Friedman’s well known and much criticized 1953 paper on “The Methodology of Positive Economics”1 proved to be convergent with Popper's falsificationist philosophy of science2. I think that this comparison is flawed. For one can assuredly contest this interpretation in view of the fact that Popper always opposed any kind of instrumentalist philosophy of science3. It is not even clear that what Friedman (...) has to say on the intricate question of the status of theories and on the function of tests has anything to do with what Popper criticizes under the general category of “instrumentalism”. What I will do here is not so much to directly challenge the Frazer-Boland interpretation as to replace it with a completely new comparison of both methodologies in order to get a new look at Friedman's methodological stance. Of course, one has to focus only on the arguments that really are comparable and leave aside those that could easily be proved to be fundamentally different, if not plainly incompatible. But, as I will try to show, the exercise is worthwhile, for this new comparison will force us to reinterpret, at least partially, what seem to me to be the two central tenets of Friedman's methodological doctrine. Of course, in order to find convergence between Friedman's and Popper's views on economic methodology, we have to read.. (shrink)

In this unique volume, some of today's most eminent political philosophers examine the thought of John Rawls, focusing in particular on his most recent work. These original essays explore diverse issues, including the problem of pluralism, the relationship between constitutive commitment and liberal institutions, just treatment of dissident minorities, the constitutional implications of liberalism, international relations, and the structure of international law. The first comprehensive study of Rawls's recent work, The Idea of Political Liberalism will be indispensable for political philosophers (...) and theorists interested in contemporary political thought.

Peirce's Reality and Berkeley's Blunders LESLEY FRIEDMAN IN A NUMBER OF HIS LATE REMARKS, Peirce makes it clear that he holds Bishop Berkeley in the highest esteem. Hailed as the "father of all modern philoso- phy," Peirce argues that Berkeley, not Kant, "first produced an Erkenntnis- theorie, or 'principles of human knowledge', which was for the most part cor- rect in its positive assertions" ? This is not at all to say that Berkeley escapes rebuke; in spite of several (...) laudatory remarks, ~ Peirce takes him to task for two errors: his view of reality as actual perception, and his neglect of real possibility. Additionally, in some passages we find Berkeley both credited for some insight and admonished for some oversight.

Genealogies in philosophy can be tricky and even a little dangerous. Lines of influence and inheritance run much more linearly on paper than in reality. I am often reminded of Robert Frost's "Mending Walls" and the attention that must be paid to what is being walled in and what is being walled out. In other words, William James and Emmanuel Levinas are not natural conversation partners. I have always read James as a fellow traveler of Edmund Husserl, and placed (...) both in a line of thought that might share Franz Brentano and Wilhelm Dilthey as forebears. In this genealogy, Levinas appears with an asterisk, or after one. Maurice Natanson described Husserlian phenomenology as an elderly grandparent who comes down to dinner just a little bit too early, making everyone uncomfortable. Seating Levinas next to James brings to mind some similar scene. What basic premises or positions do James and Levinas share? Is Levinas a Jamesian pragmatist? Is he a radical empiricist? Does James offer an ethics that parallels or even complements Levinas's rigorous ethical phenomenology? (shrink)

Robert Jervis's System Effects (1997) shares a great deal with game theory, complex-systems theory, and systems theory in international relations, yet it transcends them all by taking account of the role of ideas in human behavior. The ideational element inserts unpredictability into Jervis's understanding of system effects. Each member of a ?system? of interrelated actors interprets her situation to require certain actions based on the effects these will cause among other members of the system, but these other actors' responses (...) to one's action will be based on their own perceptions of their situation and their interpretations of what it requires. These ideas are fallible, but we cannot predict the mistakes people will make if the errors are based on information we do not have or do not interpret in the same way they do. Not only members of a system but social-scientific observers and policy makers are ignorant of others' information and interpretations, and therefore are as likely to err in their behavioral predictions as are members of the system. Thus, Jervis's book raises serious questions about how to evaluate policies directed toward producing positive system effects. The questions are unanswerable at this point, but they might be susceptible to analysis by an ambitious form of political theory. (shrink)

A diverse group of scholars reflect on the scholarship of Robert M. Veatch, the breadth of which is unmatched in modern day bioethics. Essays were written by both philosophers and clinician-philosophers, by contemporaries and mentees. They span the breadth of Bob’s work and include analyses of his ideas about death, dying and organ transplantation, human experimentation and research ethics, disability, equality and justice, the doctor-patient relationship, the history of bioethics, as well as his pedagogical approach to teaching bioethics to (...) clinicians across the health care spectrum. Recognition of Bob’s influence in the modern field of bioethics and the challenges that persist are clearly identified. (shrink)

This essay considers the nature of conceptual frameworks in science, and suggests a reconsideration of the role played by philosophy in radical conceptual change. On Kuhn's view of conceptual conflict, the scientist's appeal to philosophical principles is an obvious symptom of incommensurability; philosophical preferences are merely “subjective factors” that play a part in the “necessarily circular” arguments that scientists offer for their own conceptual commitments. Recent work by Friedman has persuasively challenged this view, revealing the roles that philosophical concerns (...) have played in preparing the way for conceptual change, creating an enlarged conceptual space in which alternatives to the prevailing framework become intelligible and can be rationally discussed. If we shift our focus from philosophical themes or preferences to the process of philosophical analysis, however, we can see philosophy in a different and much more significant historic role: not merely as an external source of general heuristic principles and new conceptual possibilities, but, at least in the most important revolutionary developments, as an objective tool of scientific inquiry. I suggest that this approach offers some insight into the philosophical significance of Newton's and Einstein's revolutionary work in physics, and of the interpretation of their work by (respectively) Kant and the logical positivists. It also offers insight into the connections between modern philosophy of science and some traditional philosophical concerns about the nature of a priori knowledge. (shrink)

Thomas Schelling, who wrote the foreword for this book, won the Nobel Prize in economics for "having enhanced our understanding of conflict and cooperation through game-theory analysis." This came after he had taught a course in game theory and rational choice to advanced students and government officials for 45 years. In this book, Robert Dodge provides in language for a broad audience, the concepts that Schelling taught. Armed with Schelling's understanding of game theory methods and his approaches to problems, (...) the general reader can improve daily decision making. Mathematics often make game theory challenging but was not a major part of Schelling's course and is even less of a factor in this book. Along with a summary of the material Schelling presented, included are problems from the course and similar less challenging questions. While considerable analysis is done with the basic game theory tool--the two-by-two matrix--much of the book is descriptive and rational decision-making is explained with stories. Chapter supplements are added to illuminate points presented by Schelling, including writings by Paul Krugman, Thomas Friedman, Steven Levitt, and others. (shrink)

Taber and Lodge's 2006 paper provides powerful evidence that one's prior beliefs shape one's reception of new evidence in a manner that can best be described as “inadvertently dogmatic.” This is especially true for people who are well informed, which dovetails with findings going back to Converse (1964) showing political beliefs to be ideologically constrained (rigid) among the relatively well informed. What may explain the coincidence of dogmatism and knowledgeability is the very process of learning about politics, which must use (...) theories, schemas, ideologies, or Lippmannesque “stereotypes” to target certain political information as germane by putting it into an interpretive framework. This interpretive process is likely to create for each of us a growing database of information that is congruent with our extant convictions but that excludes incongruent information: in light of the data we have already processed, incongruent information seems increasingly implausible (if not incomprehensible), and is therefore rationally ignored or dismissed. But this does not necessarily mean, as Taber and Lodge follow Robert Abelson in suggesting, that people are “motivated” to be dogmatic rather than being unintentionally closed minded as a result of the plausibility they involuntarily accord to their priors. Recognizing the inadvertent (unmotivated) nature of dogmatism is essential if political science is to take seriously political actors' beliefs—and to assess the gravity of the problem posed by dogmatism.

ABSTRACT While Jeffrey Friedman’s Power Without Knowledge offers a welcome corrective to the technocratic statism that dominates modern politics, Wittgenstein’s view of language suggests that the problem of ideational heterogeneity is less worrisome than Friedman maintains. In addition, Friedman’s “exitocracy” is as epistemically demanding as ordinary technocracy and thus cannot provide an alternative to it. Anarchism, however, might provide a more consistent alternative to technocracy.

Thomas Friedman’s best-selling The World is Flat has exerted much influence in the west by providing both an accessible analysis of globalisation and its economic and social effects, and a powerful cultural metaphor for globalisation. In this review, we more closely examine Friedman’s notion of the social contract, the moral centre of his hopeful vision of a globalised world. While Friedman’s social contract holds a more generous view of social and state obligation than his neoliberal economic analysis (...) might otherwise allow, his fallacious assumptions about education rest on poorly argued claims about the nature of human beings, the proper aims of schooling, and meanings of justice in a globalised world.

Robert Frost read "The Gift Outright" to the Phi Beta Kappa Society at William & Mary College almost one hundred years after Emerson delivered his famous lecture "The American Scholar" before the Society's Harvard chapter. In his talk, Emerson proclaims, "Our day of dependence, our long apprenticeship to the learning of other lands, draws to a close" (Essays and Poems 53). It is no accident that Frost's poem brings to mind Emerson.1 The possession of the American imagination by other (...) lands and its "withholding from our land of living" declare the same distractions. The distance between ourselves and our own possibilities represents for Emerson the misdirection backwards toward Europe, and not forward to the land .. (shrink)

The genetic testing and screening of children has been fraught with controversy since Robert Guthrie developed the bacterial inhibition assay to test for phenylketonuria and advocated for rapid uptake of universal newborn screening in the early 1960s. Today with fast and affordable mass screening of the whole genome on the horizon, the debate about when and in what scenarios children should undergo genetic testing and screening has gained renewed attention. United States professional guidelines — both the American College of (...) Medical Genetics /American Society of Human Genetics statement and the American Academy of Pediatrics Statement on the genetic testing of children and the new AAP and ACMG joint policy statement and technical report — as well as the old UK guidelines by the Working Part of the Clinical Genetics Society and the new United Kingdom guidelines by the British Society of Human Genetics all give the same answer: genetic testing and screening should only be done if it is in the child’s best interest.

Recent scholarship (by mainly Michael Friedman, but also by Thomas Uebel) on the philosophy of Rudolf Carnap covering the period from the publication of Carnap’s’ 1928 book Der Logische Aufbau der Welt through to the mid to late 1930’s has tended to view Carnap as espousing a form of conventionalism (epitomized by his adoption of the principle of tolerance) and not a form of empirical foundationalism. On this view, it follows that Carnap’s 1934 The Logical Syntax of Language is (...) the pinnacle of his work during this era, this book having developed in its most complete form the conventionalist approach to dissolving the pseudoproblems that often attend philosophical investigation. My task in this paper, in opposition to this trend, is to resuscitate the empiricist interpretation of Carnap’s work during this time period. The crux of my argument is that Carnap’s 1934 book, by eschewing for the most part the empiricism he espouses in the Aufbau and in his 1932 The Unity of Science, is led to a form of conventionalism that faces the serious hazard of collapsing into epistemological relativism. My speculation is that Carnap came to recognize this deficiency in his 1934 book, and in subsequent work (“Testability and Meaning”, published in 1936/37) felt the need to re-instate his empiricist agenda. This subsequent work provides a much improved empiricist epistemology from Carnap’s previous efforts and, ashistory informs us, sets the standard for future research in the theory of confirmation.

Should we implement epistemically paternalistic measures outside of the narrow range of cases, like legal trials, in which their benefits and justifiability seem clear-cut? In this chapter I draw on theories of student-led pedagogy, and Jane Friedman’s work on norms of inquiry, to argue against this prospect. The key contention in the chapter is that facts about an inquirer’s interests and temperament have a bearing on whether it is better for her to, at any given moment, pursue epistemic goods (...) via outward-facing evidence-acquisition, or in a more introspective, ratiocinative fashion. This makes problems for any non-consultative approach to assisting people in inquiry, and speaks in favor of approaches which, as with student-led pedagogy, aim to ‘tap into’ the inquirer’s interests and temperament in helping them to learn.

The subjectivism of the Austrian school of economics is a special case of Dewey's transactional philosophy, also known as pragmatism or pragmatic epistemology. The Austrian economists Carl Friedrich Menger (1840-1921) and Ludwig von Mises (1881-1973) adopted an Aristotelian deductive approach to economic issues such as social behavior and exchange. Like Menger and Mises, Friedrich A. Hayek (1899-1992) viewed scientific knowledge, even in the social sciences, as asserting and aiming for objective certainty. Hayek was particularly critical of attempts to apply the (...) empiricism of the natural sciences in the social sciences. Though Hayek was not a positivist in the sense ascribed to Milton Friedman (1912-), because he accepted the possibility of final, objective certainty, Hayek's view of scientific knowledge was closer to that of the logical positivists of the Vienna circle than to Dewey's pragmatism. Mises' a priorism, asserting and aiming for apodictic certainty, represented a more extreme form of objectivism even than Hayek's. Mises was similar in this regard to non-Austrian axiomatists such as Gerard Debreau (1921-2005), though he joined Hayek in eschewing mathematical formalism. In Dewey's contrasting view, the scientist commends new, alternative ways of knowing to the scientific community, offering more profound insight or more efficacious practical applications. Alternative ways of knowing which do not offer practical or intellectual benefits are to be rejected. Both the radical subjectivism of the Austrian school and Dewey's transactional strategy justify rejection of the mirage of social justice. Dewey's knowledge as ways of knowing suggests a broader and more fundamental critique of the socialist position in the calculation debate. The arguments presented by the Austrian school can be reformulated in terms of Dewey's pragmatic philosophy. (shrink)

Milton Friedman famously stated that the only social responsibility of business is to increase its profits, a position now known as the shareholder model of business. Subsequently, the stakeholder model, associated with Edward Freeman, has been widely seen as a heuristically stronger theory of the responsibilities of the firm to the society in which it is situated. Friedman’s position, nevertheless, has retained currency among many business thinkers. In this article, we argue that Friedman’s economic writings assume an (...) economy in which businesses operate under the protections of limited liability, which allows corporations to privatize their gains while externalizing their losses. By accepting limited liability, Friedman must also accept a view of business as embedded in social interdependency, which serves as the logical and moral foundation for corporate social responsibility (CSR). To achieve consistency with his economic principles, Friedman must either abandon limited liability or modify his doctrine on CSR and his related shareholder model of business. (shrink)

Alexander Moritzi is one of the most obscure figures in the early history of evolutionary thought. Best known for authoring a flora of Switzerland, Moritzi also published Réflexions sur l’espèce en histoire naturelle, a remarkable book about evolution with an overtly materialist viewpoint. In this work, Moritzi argues that the generally accepted line between species and varieties is artificial, that varieties can over time give rise to new species, and that deep time and turnover of species in the fossil record (...) clearly support an evolutionary interpretation of biological diversity. Moritzi was also a gradualist and viewed relationships between taxa as best represented by a ramifying tree. Although Réflexions was the first full book to be written on the topic of evolution following Lamarck’s Philosophie zoologique, Moritzi’s evolutionist contribution was stillborn, read by almost no one in his lifetime and ultimately absent from the many historiographies of evolutionary thought. This is unfortunate since many of the arguments Moritzi marshaled on behalf of an evolutionary explanation of life can be found in subsequent transmutationist writings by Frédéric Gérard, Robert Chambers, Henri Lecoq, Baden Powell, Charles Naudin, Herbert Spencer, Alfred Russel Wallace, and Charles Darwin—none of whom is likely to have ever known of the existence of Réflexions. Finally, Moritzi’s arguments, along with those found in Darwin’s private essay on evolution of the same year, provide an excellent window into the state of evolutionary thought and debate over the nature of species at the beginning of the 1840s.

Kurt Gödel criticizes Rudolf Carnap's conventionalism on the grounds that it relies on an empiricist admissibility condition, which, if applied, runs afoul of his second incompleteness theorem. Thomas Ricketts and Michael Friedman respond to Gödel's critique by denying that Carnap is committed to Gödel's admissibility criterion; in effect, they are denying that Carnap is committed to any empirical constraint in the application of his principle of tolerance. I argue in response that Carnap is indeed committed to an empirical requirement (...) vis‐à‐vis tolerance, a fact that becomes clear upon closer scrutiny of Carnap's relevant writings. *Received July 2009; revised January 2010. †To contact the author, please write to: Department of Philosophy, University of Saskatchewan, 9 Campus Drive, Saskatoon, SK S7N 5A5, Canada; e‐mail: [email protected].

A semantics for the lambda-calculus due to Friedman is used to describe a large and natural class of categorical recursion-theoretic notions. It is shown that if e 1 and e 2 are godel numbers for partial recursive functions in two standard ω-URS's 1 which both act like the same closed lambda-term, then there is an isomorphism of the two ω-URS's which carries e 1 to e 2.

Many scholars, including G. A. Cohen, Daniel Attas, and George Brenkert, have denied that a Kantian defense of self-ownership is possible. Kant's ostensible hostility to self-ownership can be resolved, however, upon reexamination of the Groundwork and the Metaphysics of Morals. Moreover, two novel Kantian defenses of self-ownership (narrowly construed) can be devised. The first shows that maxims of exploitation and paternalism that violate self-ownership cannot be universalized, as this leads to contradictions in conception. The second shows that physical coercion against (...) rational agents involves a profound status wrong--namely, their treatment as children or animals--and that this system of differential status and treatment (including self-ownership rights for rational agents) can be morally justified by our capacity for autonomy.

The story of this book of 'materials on Ludwik Fleck' is also the story of the reception of Ludwik Fleck. In this volume, some essential materials which have been produced by that reception have been gathered together.

In the wake of both the semiotic and the psychoanalytic revolutions, how is it possible to describe the object of religious worship in realist terms? Semioticians argue that each object is known only insofar as it gives birth to a series of signs and interpretants (new signs). From the psychoanalytic side, religious beliefs are seen to belong to transference energies and projections that contaminate the religious object with all-too-human complexes. In Nature's Religion, distinguished theologian and philosopher Robert S. Corrington (...) weaves together the concept of infinite semiosis with that of the transference to show that the self does have access to something in nature that is intrinsically religious. Corrington argues that signs and our various transference fields can and do connect us with fully natural religious powers that are not of our own making, thereby opening up a path past the Western monotheisms to a capacious religion of nature. With a foreword by Robert C. Neville, Nature's Religion is essential reading for philosophers of religion, scholars of the psychology of religion, and theologians. (shrink)

Through an analysis of key themes in Heidegger's work, the book challenges the traditional theological appropriation of Heidegger and the usual characterizations of religious thinking in terms of faith or belief in, or experience of, some ultimate reality. Heidegger, it is argued, offers a unique approach to a variety of issues and problems in contemporary religious thought and philosophy of religion that results in understanding religious thinking as a resolute openness to the holiness and meaningfulness of the world.

Contemporary republicanism is characterized by three main ideas: free persons, who are not subject to the arbitrary power of others; free states, which try to protect their citizens from such power without exercising it themselves; and vigilant citizenship, as a means to limit states to their protective role. This book advances an economic model of such republicanism that is ideologically centre-left. It demands an exit-oriented state interventionism, one that would require an activist government to enhance competition and resource exit from (...) dominating relationships within markets of all types, be they marital, labour, or residential. The substantial intervention and redistribution necessitated by such an approach make it leftist, while its tendency to work with rather than against the grain of markets makes it centrist. It is, in short, a contribution to progressive republican political thought, but one that is less social-democratic than market-democratic in character. (shrink)
