The feasibility of reversing human aging within a matter of decades has traditionally been dismissed by all professional biogerontologists, on the grounds that not only is aging still poorly understood, but also many of those aspects that we do understand are not reversible by any current or foreseeable therapeutic regimen. This broad consensus has recently been challenged by the publication, by five respected experimentalists in diverse subfields of biogerontology together with three of the present authors, of an article (Ann NY (...) Acad Sci 959, 452–462) whose conclusion was that all the key components of mammalian aging are indeed amenable to substantial reversal (not merely retardation) in mice, with technology that has a reasonable prospect of being developed within about a decade. Translation of that panel of interventions to humans who are already alive, within a few decades thereafter, was deemed potentially feasible (though it was not claimed to be likely). If the prospect of controlling human aging within the foreseeable future cannot be categorically rejected, then it becomes a matter of personal significance to most people presently alive. Consequently, we suggest that serious public debate on this subject is now warranted, and we survey here several of the biological, social and political issues relating to it.

Is logic normative for reasoning? In the wake of work by Gilbert Harman and John MacFarlane, this question has been reduced to: are there any adequate bridge principles which link logical facts to normative constraints on reasoning? Hitherto, defenders of the normativity of logic have exclusively focussed on identifying adequate validity bridge principles: principles linking validity facts—facts of the form 'gamma entails phi'—to normative constraints on reasoning. This paper argues for two claims. First, for the time being at least, Harman’s (...) challenge cannot be surmounted by articulating validity bridge principles. Second, Harman’s challenge can be met by articulating invalidity bridge principles: principles linking invalidity facts of the form 'gamma does not entail phi' to normative constraints on reasoning. In doing so, I provide a novel defence of the normativity of logic. (shrink)

Sense of agency refers to the sense of initiating and controlling actions in order to influence events in the outside world. Recently, a distinction between implicit and explicit aspects of sense of agency has been proposed, analogous to distinctions found in other areas of cognition, notably learning. However, there is yet no strong evidence supporting separable implicit and explicit components of sense of agency. The so-called ‘Perruchet paradigm’ offers one of the few convincing demonstrations of separable implicit and explicit learning (...) systems. We adopted this approach to evaluate the implicit–explicit distinction in the context of a simple task in which outcomes were probabilistically caused by actions. In line with our initial predictions, we found evidence of a dissociation. We discuss the implications of this result for theories of sense of agency. (shrink)

In his book The Retreat to Commitment Professor Bartley raised an important problem: can rationalism can rationalism be held in a rational way, that is, in a way that complies with its own requirements? Or is there bound to be something irrational in the rationalist's position? Briefly, Hartley's answer was that an element of irrationalism is involved in extant versions of rationalism; however, Bartley proposed a new version of rationalism that can, he claimed, be held in a way that is (...) rational according to its own account of rationality. Bartley called this ‘Comprehensively Critical Rationalism’. (shrink)

"Contemporary Mind - Some Modern Answers" is a fantastic collection of essays by English science writer John W. Sullivan. They deal with a range of subjects, ranging from mysticism and immortality to the relationship between science and art. John William Navin Sullivan (1886 - 1937) was a literary journalist and popular science writer most famous for his study of Beethoven. He is also responsible for having written some of the earliest non-technical accounts of Einstein's General Theory of Relativity, and he (...) was acquainted with many important writers in London in the 1920s, including John Middleton Murry, Aldous Huxley, Wyndham Lewis, Aleister Crowley and T. S. Eliot. Other notable works by this author include "Aspects of Science" (1923), "Aspects of Science: Second Series" (1926), and An Outline of Modern Knowledge (1931). Contents include: "The Balanced Life," "The Problem of Suffering," "The Necessity of Mysticism," "Human Immortality," "A Dissertation on Beethoven," "The Scientific Outlook," "A Dissertation on Maxwell," "New Principles," "A Dissertation on Newton," "Science and Art," "Mathematics and Culture," "Sir Josiah Stamp," "Mr. Aldous Huxley," etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork. (shrink)

One of the most serious pre-occupations of post-medieval philosophy has been to distinguish those kinds of assertion which are either true or false from those which are neither true nor false. A solution to this problem would be of the highest importance. It would indicate in what areas rational inquiry has some hope of success and in what areas it is doomed to frustration. It would tell us, for example, whether it is worth trying to think about the possible mistakenness (...) of our moral principles, or whether such thinking is bound to be ineffective since no truth or falsity attaches to them.

When philosophers put forward claims for or against 'property', it is often unclear whether they are talking about the same thing that lawyers mean by 'property'. Likewise, when lawyers appeal to 'justice' in interpreting or criticizing legal rules we do not know if they have in mind something that philosophers would recognize as 'justice'. J. W. Harris here examines the legal and philosophical underpinnings of the concept of property and offers a new analytical framework for understanding property and justice.

The purpose of this brief introduction is to describe the origin of the papers here presented and to acknowledge the help of some of the many individuals who were involved in the preparation of this volume. Of the eighteen papers, nine stem from the annual fall colloquium of the Depart ment of Philosophy at the University of Western Ontario held in London, Ontario from November 10 to November 12, 1967. The colloquium was entitled 'Philosophical Logic'. After some discussion, the editors (...) decided to retain that title for this volume. Von Wright's paper 'On the Logic and Ontology of Norms' is printed here after some revision. A. R. Anderson commented on the paper at the colloquium, but his comments here are based upon the revised version of the von Wright paper. The chairman of the session at which von Wright's paper was read and discussed was T. A. Goudge. Aqvist's paper 'Scattered Topics in Interrogative Logic', and Belnap's comments, 'Aqvist's Cor rections-Accumulating Question-Sequences', are printed as delivered. The chairman of the Aqvist-Belnap session was R. E. Butts. Wilfrid Sellars' paper 'Some Problems about Belief' is printed as delivered at the col loquium, but 'Quantifiers, Beliefs, and Sellars' by Ernest Sosa is a revision of his comments at the colloquium. That session was chaired by G. D. W. Berry. Ackermann's paper 'Some Problems oflnductive Logic', as well as Skyrms' comments, are printed as delivered. (shrink)

This paper studies the use of hypotheses schemes in generatinginductive predictions. After discussing Carnap–Hintikka inductive logic,hypotheses schemes are defined and illustrated with two partitions. Onepartition results in the Carnapian continuum of inductive methods, the otherresults in predictions typical for hasty generalization. Following theseexamples I argue that choosing a partition comes down to making inductiveassumptions on patterns in the data, and that by choosing appropriately anyinductive assumption can be made. Further considerations on partitions makeclear that they do not suggest any solution (...) to the problem of induction.Hypotheses schemes provide the tools for making inductive assumptions, but theyalso reveal the need for such assumptions.

To what extent is time similar to space? in this paper it is shown that the claim, Made by richard taylor among others, That time and space are "radically alike" is unfounded. This claim can be supported only by employing the notion of temporal parts. It is shown that if objects are regarded as having temporal parts as well as spatial parts, Then serious disanalogies exist between time and space. Furthermore, If objects are said to have temporal parts, Then it (...) must also be held that time is in a very important sense "prior" to space and this that time and space are not only unlike in certain respects but indeed are radically dissimilar. Moreover, The so-Called "manifold theory of time" necessarily makes use of the notion of temporal parts and therefore should hold that time and space are quite unlike. But since an important part of the manifold theory of time is the claim that time and space are very much alike, This theory is to that extent not satisfactory. (shrink)

Although the theory of definability had many important antecedents—such as the descriptive set theory initiated by the French semi-intuitionists in the early 1900s—the main ideas were first laid out in precise mathematical terms by Alfred Tarski beginning in 1929. We review here the basic notions of languages, explicit definability, and grammatical complexity, and emphasize common themes in the theories of definability for four important languages underlying, respectively, descriptive set theory, recursive function theory, classical pure logic, and finite-universe logic. We review (...) the history of previous studies of the similarities and differences in the theories of definability of the first three of these four languages. A seminal role leading toward unification of the theories has been played by the separation principles introduced by Nikolai Luzin in 1927. Emphasizing analogies and driving toward further unification embracing finite-universe logic we concentrate on a simple example—the first and second separation principles for existential-universal first-order sentences . Using this as a test case for the fundamental problem of how to “finitize” arguments in classical pure logic to the finite-universe case, we are led to the analogous negative solution by using the theory of certain special graphs: a graph is - special for any positive integers m , n , p , q iff it is bipartite with m red points and n blue points and for every p -tuple of red points there is a blue point to which they are all connected . As an aside we introduce for further study a natural “Ramseyesque” increasing sequence A of positive integers, where A is the least positive integer n for which an -special graph exists. (shrink)

According to tradition, logic is normative for reasoning. According to many contemporary philosophers of logic, there is more than one correct logic. What is the relationship between these two strands of thought? This paper makes two claims. First, logic is doubly normative for reasoning because, in addition to constraining the combinations of beliefs that we may have, logic also constrains the methods by which we may form them. Second, given that logic is doubly normative for reasoning, a wide array of (...) logical pluralisms are inconsistent with the normativity of logic as they entail contradictory claims about how agents ought to reason. Thus, if logic is normative for reasoning, these pluralisms are untenable. (shrink)

My reason for bringing up the familiar matter of phenomenalism is both critical and historical. Almost to a man those who have been interested in arguing for or against phenomenalism have assumed that Berkeley was a phenomenalist. Now if Berkeley's doctrine is appropriately named “phenomenalism,” then it is a phenomenalism of a quite different stripe from the twentieth century variety, though many who have described his doctrine as phenomenalism have not sufficiently stressed the difference.

In France, as in other European countries, especially Britain and Germany, the nineteenth century was a period of great progress and achievement in science. This would still have been true if Claude Bernard and Louis Pasteur had been the only outstanding French scientists of the nineteenth century, whereas there were, of course, many others apart from an impressive number of brilliant French mathematicians. Nevertheless, although it was a great century for French science there was perhaps something rather disappointing about it, (...) and something rather ingrowing about the attitude of French scientists towards scientific developments in other countries. For example, the French took it hard that the creator of the theory of evolution should have been an Englishman, remembering too late Darwin's predecessor Lamarck, and they certainly were very slow in accepting Darwin's theory of evolution.1 Again, the French may have felt that after the important contributions of French scientists such as Coulomb, Poisson, Biot and, above all, Ampère, the theory of electricity and magnetism which is today principally associated with the names of Faraday and Maxwell should have been created by a Frenchman. Once again this new theory was only accepted very slowly and hesitantly, and even unwillingly, in France—one thinks, for example, of the criticisms levelled at the theory by Pierre Duhem in his “The Aim and Structure of Physical Theory”.2 Of course it might be that if one knew how to weigh properly the various achievements of French scientists in different branches of science one would find that, allowing for her rather static population during the nineteenth century, thetotalcontribution of France compared well with those of Britain and Germany. Nevertheless, in one case at least, that of theoretical physics, there seems to have been an unmistakable failure to live up to the promise of the beginning of the century. The purpose of this paper is to advance possible reasons to explain this failure. (shrink)

Artificial agents (AAs), particularly but not only those in Cyberspace, extend the class of entities that can be involved in moral situations. For they can be conceived of as moral patients (as entities that can be acted upon for good or evil) and also as moral agents (as entities that can perform actions, again for good or evil). In this paper, we clarify the concept of agent and go on to separate the concerns of morality and responsibility of agents (most (...) interestingly for us, of AAs). We conclude that there is substantial and important scope, particularly in Computer Ethics, for the concept of moral agent not necessarily exhibiting free will, mental states or responsibility. This complements the more traditional approach, common at least since Montaigne and Descartes, which considers whether or not (artificial) agents have mental states, feelings, emotions and so on. By focussing directly on mind-less morality we are able to avoid that question and also many of the concerns of Artificial Intelligence. A vital component in our approach is the Method of Abstraction for analysing the level of abstraction (LoA) at which an agent is considered to act. The LoA is determined by the way in which one chooses to describe, analyse and discuss a system and its context. The Method of Abstraction is explained in terms of an interface or set of features or observables at a given LoA. Agenthood, and in particular moral agenthood, depends on a LoA. Our guidelines for agenthood are: interactivity (response to stimulus by change of state), autonomy (ability to change state without stimulus) and adaptability (ability to change the transition rules by which state is changed) at a given LoA. Morality may be thought of as a threshold defined on the observables in the interface determining the LoA under consideration. An agent is morally good if its actions all respect that threshold; and it is morally evil if some action violates it. That view is particularly informative when the agent constitutes a software or digital system, and the observables are numerical. Finally we review the consequences for Computer Ethics of our approach. In conclusion, this approach facilitates the discussion of the morality of agents not only in Cyberspace but also in the biosphere, where animals can be considered moral agents without their having to display free will, emotions or mental states, and in social contexts, where systems like organizations can play the role of moral agents. The primary cost of this facility is the extension of the class of agents and moral agents to embrace AAs. (shrink)

For pragmatic reasons more attention should be devoted to the serious study of religion. Although religions inspire great achievements of human creativity, it is important to understand them because they also promote violence and warfare. One can understand the unacceptable face of religion when one sees why religions matter to those who belong to them; why they are bound to be conservative, especially in times of stress; and why, therefore, believers become very passionate about defending the boundaries of their particular (...) religious systems. Such understanding provides a realistic basis for working toward the peaceful coexistence of conflicting religious systems. (shrink)

Many books have been written on Greek dance. The fault which bedevils a large number of them is that their authors have tried to recreate the movements of the dances from the artistic evidence without taking into account the conventions of Greek vase-painting and sculpture. Other books, and they are the most useful, set out the literary and the artistic evidence without attempting to reconstruct the dances. Rarely, however, are the wider implications considered, and it is these which I wish (...) to discuss here. More analysis and discussion of the evidence for many of my statements is no doubt required, but the place for that is a book rather than an article which ranges over a comparatively large field.

This paper outlines the qualitative foundations of a “quasiclassical” theory in which particles are pictured as spatially extended periodic excitations of a universal background field, interacting with each other via nonlinearity in the equations of motion for that field, and undergoing collapse to a much smaller volume if and when they are detected. The theory is based as far as possible directly on experiment, rather than on the existing quantum mechanical formalism, and it offers simple physical interpretations of such concepts (...) as mass, 4-momentum, interaction, potentials, and quantization; it may lead directly to the standard equations of quantum theory, such as the multiparticle Schrödinger equation, without going through the conventional process of “quantizing” a classical theory. The theory also provides an alternative framework in which to discuss wave-particle duality and the quantum “measurement problem”; in particular, it is suggested that the unpredictability of quantum phenomena may arise from “deterministic chaos” in the behavior of the background field.

In this paper an attempt is made to interpret inertial mass as a consequence of the invariant periodicity associated with physical de Broglie waves. In the case of a free particle, such waves, observed from an arbitrary reference frame, would exhibit the velocity-dependent wavelength given by de Broglie's relation; and it is conjectured that the inertial and additive properties of mass (or, more precisely, the conservation of momentum and energy) can be related to nonlinear interference effects occurring between the de (...) Broglie waves for different particles. This picture could throw light on the physical meaning of quantization and suggests the possibility of reformulating classical and quantum mechanics in terms of a “quasi-classical” nonlinear field theory in which both inertial and quantization effects result essentially from the periodicity of de Broglie waves. (shrink)

The author has recently proposed a “quasi-classical” theory of particles and interactions in which particles are pictured as extended periodic disturbances in a universal field χ(x, t), interacting with each other via nonlinearity in the equation of motion for χ. The present paper explores the relationship of this theory to nonrelativistic quantum mechanics; as a first step, it is shown how it is possible to construct from χ a configuration-space wave function Ψ(x 1,x 2,t), and that the theory requires that (...) Ψ satisfy the two-particle Schrödinger equation in the case where the two particles are well separated from each other. This suggests that the multiparticle Schrödinger equation can be obtained as a direct consequence of the quasi-classical theory without any use of the usual formalism (Hilbert space, quantization rules, etc.) of conventional quantum theory and in particular without using the classical canonical treatment of a system as a “crutch” theory which has subsequently to be “quantized.” The quasi-classical theory also suggests the existence of a preferred “absolute” gauge for the electromagnetic potentials.

Can we understand conscious experience? It can seem that the answer is ‘no’. Even when we have well-supported cognitive accounts of consciousness, such as global workspace theory, experience itself seems to elude our grasp. It is easy to see how a global workspace might be a useful adaptation, much harder to see what role is played by conscious experience. For instance, if I'm looking for a blue notebook, why do I need to experience colours? Why wouldn't it suffice to have (...) an unconscious mechanism that recognized colours, and could make such information available to other systems? Why couldn't the mechanisms of the workspace operate without experience at all? (shrink)

ABSTRACT This essay explores the possibility for a phenomenology of Christian vocational calling through conversation with Jean-Paul Sartre’s existential-ontology. By demonstrating how Sartre’s account of nothingness comports with a Rahnerian understanding of God as absolute mystery and how Sartre’s account of bad faith further opens up an understanding of ontological self-identity as a turn away from God, we can establish a phenomenology of Christian vocation as one’s owning each finite situation in terms of its divinely available possibilities rather than simply (...) its given conditions. Divine call thus occurs where one’s possibilities for boundless becoming are freely recognized in any situation and are further apprehended in light of the character of God to become the possibilities for the freedom and calling of others.

For each regular cardinal κ, we set up three systems of infinitary type logic, in which the length of the types and the length of the typed syntactical constructs are $\Sigma _{}$, the global system $\text{g}\Sigma _{}$ and the τ-system $\tau \Sigma _{}$. A full cut elimination theorem is proved for the local systems, and about the τ-systems we prove that they admit cut-free proofs for sequents in the τ-free language common to the local and global systems. These two results (...) follow from semantic completeness proofs. Thus every sequent provable in a global system has a cut-free proof in the corresponding τ-systems. It is, however, an open question whether the global systems in themselves admit cut elimination. (shrink)

The tradition that Socrates had two wives at once, Xanthippe and Myrto, though an established one among ancient scholars, has met with blank incredulity in modern times. It impugns the character of Socrates, who has been established by Plato's martyrology as the unimpeachable patron saint of Western philosophy. And it appears to cast a slur on Greek marriage—not that the guiding lines of this somewhat ramshackle institution are perfectly known.

When managing their emotions, individuals often recruit the help of others; however, most emotion regulation research has focused on self-regulation. Theories of emotion and aging suggest younger and older adults differ in the emotion regulation strategies they use when regulating their own emotions. If how individuals regulate their own emotions and the emotions of others are related, these theorised age differences may also emerge for interpersonal emotion regulation. In two studies, younger and older adults’ intrapersonal and interpersonal emotion regulation strategy (...) choices were examined via self-report and behavioural assessments of regulating the emotions of another participant (Study 1; N = 80) and of a virtual human (Study 2; N = 100). Across both studies, younger adults reported greater intrapersonal suppression but not greater reappraisal. Younger and older adults were generally similar (supported by Bayesian analyses) for both self-reported and behavioural interpersonal emotion regulation strategies. Behavioural interpersonal emotion regulation was not related to self-reported intra- and interpersonal preferences. These results suggest interpersonal emotion regulation in ageing may show distinct patterns from theorised age differences in intrapersonal emotion regulation. (shrink)

The most promising way to regard thought experiment is as a species of experiment, alongside concrete experiment. Of the authors who take this view, many portray thought experiment as possessing evidential significance intrinsically. In contrast, concrete experiment is nowadays most convincingly portrayed as acquiring evidential significance in a particular area of science at a particular time in consequence of the persuasive efforts of scientists. I argue that the claim that thought experiment possesses evidential significance intrinsically is contradicted by the history (...) of science. Thought experiment, like concrete experiment, has evidential significance only where particular assumptions--such as the Galilean doctrine of phenomena--are taken to hold; under alternative premises, in themselves equally defensible, thought experiment is evidentially inert.

The phrase “Cosmic Purpose” and others akin to it are familiar enough, particularly in the literature of edification. It is the aim of this article to examine the idea the words convey rather more closely than we do in our common use of them; to deflate the expression, so to speak, of those gaseous suggestions of “uplift” which too often hang about it. The question involved is, of course, in what sense, if in any, purpose may be attributed to the (...) Cosmos, to the universe in its totality. And we have to ask, in case the term so used should turn out to be really misused, Is it a sheer error that dissolves away under criticism, or is there some valid core of meaning which may be restated in other terms? If these are well-worn questions, yet the problem is too fundamental for them ever to be altogether trite. (shrink)

Contemplating the catastrophic course of the Nazi Revolution we may well find it all too easy to see nothing in the spectacle but the nether darkness made visible; and if we are advised that it is not merely permissible but highly advisable to learn from the enemy, we may be tempted to think that whatever the Nazi war-machine has to teach the strategist and the technician, the political history of Germany in the last decade, and in particular the political ideology (...) that has imposed itself upon the German mind with such apparent thoroughness, can yield only the negative lesson of a warning, by displaying upon the world-wide stage the doomful consequences of wrong principles ruthlessly pushed to their extreme. But it is certainly an error to deny that nothing of more positive value has emerged out of the revolutionary cauldron: and indeed it would be more than strange, where such whole-hearted energies of mind are being enlisted in the evil cause of Nazism, if none of its votaries had ever stumbled for a time into wisdom.

Since Peter Geach coined the phrase in 1966 there has been much discussion among scholars of the "Socratic fallacy." No consensus presently exists on whether Socrates commits the "Socratic fallacy"; almost all scholars agree, however, that the "Socratic fallacy" is a bad thing and that Socrates has good reason to avoid it. I think that this consensus of scholars is mistaken. I think that what Geach has labeled a fallacy is no fallacy at all, but a perfectly innocent consequence of (...) Platonic epistemology. The "Socratic fallacy" arises from the "Priority of Definition" principle (PD). Plato is committed to (PD) in the Meno. The Meno also contains a famous discussion of the difference between episteme and doxa (97a ff.). If we understand what Plato meant by episteme we can see that he must be committed to (PD); but we can also see that (PD) has none of the harmful consequences Geach attributes to it. Geach's view is indebted to Wittgenstein's philosophy of language. (PD) is implausible on this reading of the verb "to know," but not on Plato's. Plato claims that a demand for an explanation is appropriate wherever a claim to knowledge is made. Plato links the concept of episteme explicitly with the concept of logos; the connection between the terms may have been analytic. It does not follow from the Platonic conception of knowledge, as Geach argues, that it is "no use" using examples to establish general definitions. All that follows is that one cannot know that an alleged example of a term T is a genuine example until one has a general account of what it is to be T. Without the stronger conclusion, Geach cannot establish that the "Socratic fallacy" is a fallacy. (shrink)

This thesis attempts to show that Georg Lukacs' Marxist theory of realism is best understood, not as a self sufficient body of theory, but in the context of his pre- Marxist theory of literature and his,role in the Communist movement, A comparison of the theory expounded in "Die Seele and die Fonaen" and "Die Theorie des Romans" with the main positions of "Geschichte und Kiassenbewusstsein" reveals that it was remarkably easy for Lukacs to accommodate his literary theory within the newly-acquired (...) philosophy. An examination of Lukacs' career shows that his move to Marxism was motivated by a search for the practical instrument to implement the ideal which was the mainspring behind both his own life and, in his theory, all great literature, namely, the classical ideal of harmony. The resulting change in emphasis from aesthetics to political action led, in the thirties, to the attempt to synthesize both in a cultural campaign. Political pressure, combined with the genuine belief that the excesses of Stalinism were the acceptable price of resistance to the overriding threat of fascism, resulted in the employment of a rigid determinism, deplored ill others, which was incompatible with the core of his understanding of literary realism. The creation of realism was, however, for both the pre- Marxist and the Marxist Lukacs, ultimately inexplicable in materialist terms. (shrink)

The Dative or Ablative of this ‘plurale tantum’ was used by one of the earlier Republican writers.

This article argues that time-asymmetric processes in spacetime are enantiomorphs. Subsequently, the Kantian puzzle concerning enantiomorphs in space is reviewed to introduce a number of positions concerning enantiomorphy, and to arrive at a dilemma: one must either reject that orientations of enantiomorphs are determinate, or furnish space or objects with orientation. The discussion on space is then used to derive two problems in the debate on the direction of time. First, it is shown that certain kinds of reductionism about the (...) direction of time are at variance with the claim that orientation of enantiomorphic objects is intrinsic. Second, it is argued that reductive explanations of time-asymmetric processes presuppose that enantiomorphic processes do not have determinate orientation. (shrink)

In 1947, Jacques Maritain argued before the UN that “men mutually opposed in their theoretical conceptions can come to a merely practical agreement regarding a list of human rights.” Maritain justified this thesis using a progressive theory of the natural law which rests on a distinction between the natural law as operative in human nature and the natural law as known and articulated.

Discussions on the distinction between philosophy and science are apt to seem rather futile and academic. They would quickly lose that character if they were thought to have any bearing on the question of social survival or decay. That they have such a bearing follows if the following considerations are true, and I think that they are: first, that amongst the conditions of a society’s survival an indispensable one is the prevalence within it of a certain vision of it; secondly, (...) that in its type this vision is akin to philosophy and not to science; and thirdly, that the due cultivation of it necessitates our being careful not to mistake its affiliations.

This present essay represents an effortto discern a direction in which such a collaboration might have deeply and felicitously influenced Polanyi’s interpretation and celebration of his own poignant, yet quite restless, religious sensibilities.

Having remarked that "competing and mutually contradictory philosophies may be formulated in different languages," Landesman concludes that "the generalization that the speaking of a given language by a given philosopher is either a necessary or sufficient condition for the formulation of his explicit philosophy would seem to be false." I do not believe that the conclusion follows. Elsewhere, I have tried to show that what I call the "strong interpretation" of the Sapir-Whorf hypothesis can be assimilated to the notion of (...) "untranslatability" in such a way that it becomes equivalent to the denial of the position held by Roman Jakobson that "All cognitive experience and its classification is conveyable in any existing language." To deny Jakobson's thesis is equivalent to the assertion that there is at least one language for which there is at least one other language such that the first cannot translate the second. Letting "Txy" stand for "x translates y," and "Lx" for "x is a language," Jakobson's thesis goes over in symbols as. (shrink)

Reanimated for the contemporary literature in the writings of Quine, [16]) and Kuhn [7], the conventionalism of Duhem [2] and Poincaré [12] has emerged in the last few years as one of the genuinely interesting topics in the philosophy of science. The theory in question—let us follow Grünbaum [3] in calling it the D-thesis, after its founder, Pierre Duhem—claims three things: a single scientific hypothesis H is never disconfirmable in isolation from its fellow; every single hypothesis H of science presupposes, (...) explicitly or implicitly, the support of a conjunction A = A, • A2 • … • Am of auxiliary assumptions or hypotheses; the failure of an observational consequence of H in face of contradictory evidence disconfirms only the conjunction of H and A, not H alone—i.e. establishes only ∼. The logical picture is as follows. (shrink)

The articles collected in this volume are concerned with the transmission and development of the Greek achievement among Syriac scholars of the Fertile Crescent during the four centuries after 500CE, particularly in the fields of rhetoric and philosophy. Cumulatively they show how many aspects of Greek culture were received and elaborated in Syriac, and contribute to understanding the ways in which that culture exercised a powerful influence on the medieval Near East and the burgeoning Islamic civilisation.
