Marsilio Ficino (1433-1499) was one of the luminaries of the Florentine Renaissance and the scholar responsible for the revival of Platonism. The translator and interpreter of the works of both Plato and Plotinus as well as of various Hermetic and Neoplatonic texts, Ficino was also a musician, priest, magus and psychotherapist, an original philosopher and the author of a vast and important correspondence with the intellectual figures of his day including Lorenzo the Magnificent. Professor Allen has become the foremost interpreter (...) of Ficino's metaphysics and mythology, and the ancient sources they draw upon; and this collection of essays assembles his work on Ficino's complex interrogation of Platonic 'theology' as not only a preparation for Christianity but as an enduring medium for intellectuals to explore and to express Christian truths.

We answer some problems set by Priest in [11] and [12], in particular refuting Priest's Conjecture that all LP-models of Th(N) essentially arise via congruence relations on classical models of Th(N). We also show that the analogue of Priest's Conjecture for I δ₀ + Exp implies the existence of truth definitions for intervals [0,a] ⊂ₑ M ⊨ I δ₀ + Exp in any cut [0,a] ⊂e K ⊆ M closed under successor and multiplication.

Postnatally, heart muscle cells almost completely lose their ability to divide, which makes their loss after trauma irreversible. Potential repair by cell grafting or mobilizing endogenous cells is of particular interest for possible treatments for heart disease, where the poor capacity for cardiomyocyte proliferation probably contributes to the irreversibility of heart failure. Knowledge of the molecular mechanisms that underly formation of heart muscle cells might provide opportunities to repair the diseased heart by induction of (trans) differentiation of endogenous or exogenous (...) cells into heart muscle cells. We briefly review the molecular mechanisms involved in early development of the linear heart tube by differentiation of mesodermal cells into heart muscle cells. Because the initial heart tube does not comprise all the cardiac compartments present in the adult heart, heart muscle cells are added to the distal borders of the tube and within the tube. At both distal borders, mesodermal cell are recruited into the cardiac lineage and, within the heart tube, muscular septa are formed. In this review, the relative late additions of heart muscle cells to the linear heart tube are described and the potential underlying molecular mechanisms are discussed. BioEssays 26:248–261, 2004.

In Pure Inductive Logic, the rational principle of Predicate Exchangeability states that permuting the predicates in a given language L and replacing each occurrence of a predicate in an L-sentence phi according to this permutation should not change our belief in the truth of phi. In this paper we study when a prior probability function w on a purely unary language L satisfying Predicate Exchangeability also satisfies the principle of Unary Language Invariance.

In this article, I develop the point that whereas talent is the basis for desert, talent itself is not meritocratically deserved. It is produced by three processes, none of which are meritocratic: talent is unequally distributed by the rigged lottery of birth, talent is defined in ways that favor some traits over others, and the market for talent is manipulated to maximally extract advantages by those who have more of it. To see how, we require a sociological perspective on economic (...) rent. I argue that talent is a major means through which people seek rent in modern-day capitalism. Talent today is what inherited land was to feudal societies; an unchallenged source of symbolic and economic rewards. Whereas God sanctified the aristocracy’s wealth, contemporary privilege is legitimated by meritocracy. Drawing on the work of Gary Becker, Pierre Bourdieu, and Jerome Karabel, I show how rent-seeking in modern societies has come to rely principally on rent-definition and creation. Inequality is produced by the ways in which talent is defined, institutionalized, and sustained by the moral deservingness we attribute to the accomplishments of talents. Consequently, today’s inequalities are as striking as ever, yet harder to challenge than ever before. (shrink)

‘Now that all parts and members of the mortal creature had been fashioned into one, seeing that it must be the creature's lot for reasons of necessity to spend its life in the domain of fire and air and that it was like to waste away being continually melted and emptied by their onslaught, the gods contrived reinforcement for it. Blending a being kindred to man's being but with different shapes and senses, they brought it into life, a second kind (...) of living creature. Trees, plants, and seeds are these, and those among them which are cultivated types to-day have arrived at their mild benevolence to man only because they have been civilized by his husbandry; formerly only the wild kinds existed, for these are older than the cultivated. Now everything that is alive, whatever it be, may perfectly correctly and of right be termed ‘a living creature’. The creature now in question has at any rate the third kind of soul which our discourse told us is situated between the midriff and the navel. This kind of soul has nothing of opining or of reasoning mind, but it has sensation of pleasant and painful with attendant desires. For continually it is subject to every impression. Its manner of birth has not granted it the power to revolve by itself in itself upon itself rejecting outside motion and asserting its own and thus by beholding all things by native endowment of soull to reason out aught of its own concerns. So it has life and is not some second being other than a living creature, but it stays fixed, rooted, motionless, for it has never been granted movement of its own initiation.’. (shrink)

Virgil, in his description of the establishment of a new city by Aeneas for those Trojans who wished to remain in Sicily, is thinking of the Roman practice of colonial foundation: ‘Meanwhile Aeneas marked out the city with the plough and allocated the houses ’. We may note the personal role of the founder, the ploughing of the ritual first furrow, the organized grants to the settlers and the equality of treatment implied in the use of lot . Virgil was (...) writing at the end of the first century B.C. at a time of great activity in land distribution, but the Romans had been founding colonies from the mid fourth century. Each colony involved the creation of an urban area and the settlement of people on the surrounding agricultural land, and so perpetuated the city state, which was central to ancient life and culture. Indeed a colony was a smaller image of Rome itself. In the early Republic, colonies, either of Latins or of Roman citizens, were established on the periphery of Roman territory, largely for military and strategic reasons. Between 200 and 173 B.C. more than 40,000 may have received plots of land, amounting to about 1,000 square miles of territory. Later, the motives for colonial foundations became more complex, being closely connected with increasing economic and political problems. There can have been few more important aspects in the development of colonies than the need to find land for discharged troops. These in the main were rank and file soldiers who would expect equal shares in land allocations. (shrink)

Sidgwick is usually considered to be a utilitarian, and with good reason. In an autobiographical fragment he tells us that his “first adhesion to a definite Ethical system was to the Utilitarianism of Mill”, and that after a variety of intellectual changes he became “a Utilitarian again, but on an Intuitional basis.” He refers to himself in other works and in letters as a utilitarian, and he was so viewed by his contemporaries. Hence it is understandable that Albee should view (...) The Methods of Ethics as “an independent contribution to the literature of Utilitarianism”, labelling it “the last authoritative utterance of traditional Utilitarianism”, and that almost everyone who discusses the book should agree with this classification of it. Yet Sidgwick did not himself say that the Methods is a defense or a restatement of utilitarianism. On the contrary: he was from the first at pains to disavow any intention of proving a system of morality and to insist that he is presenting only an examination of “the different methods of obtaining reasoned convictions as to what ought to be done which are to be found … in the moral consciousness of mankind generally.” In the “Preface” to the second edition he bemoans the misunderstanding which led critics to suppose that he was “writing as an assailant of two of the methods” he examines. One critic, he complains, thought he was giving “mere hostile criticism” of intuitionism, another “has constructed an article on the supposition that my principal object is ‘the suppression of Egoism’”. Yet a third critic, he remarks dryly, referring to a savage attack by F. H. Bradley, “has gone to the length of a pamphlet under the impression that the ‘main argument’ of my treatise is a demonstration of Universalistic Hedonism. I am concerned”, he comments, “to have caused so much misdirection of criticism”; and he goes on to reiterate his position about the two forms, egoistic and universalistic, of hedonism: “I do not hold the reasonableness of aiming at happiness generally with any stronger conviction than I do that of aiming at one’s own.”.

Preparing to lecture on Aristotle's contribution to Nursing at the International Philosophy of Nursing Conference August 22, 2016, in Quebec City, Quebec, Canada, I came upon the recently published article by my IPONS colleague, Allmark (2016), “Aristotle for Nursing.” Allmark (2016) provides a comprehensive and understandable overview of Aristotle's philosophical system including the substantial nature of being and the four causes of change. Nurses using Aristotle to support practice and theoretical research will benefit from a careful reading of Allmark to (...) enrich their use of the realist understanding of knowledge of nature (epistemology) and the matter–form causal relationships within natural being (ontology and teleology). Allmark carefully displays the distinction between good health and flourishing; a distinction sometimes hard to grasp. Nurses are concerned with the end of health, but cannot achieve for others, the fullness of living which is flourishing.We will limit ourselves to expanding three areas that seem important, first, that nursing is much more than a productive science or craft, second, that Aristotle does provide an important note on the persistence of the soul, and, third, while Aristotle does not address the possibility of a personal creative highest being as Allmark says, his references to the divine are worth considering.

This passage is discussed in AJPb 97 , 252, by D. R. Shackleton Bailey, who rightly draws attention to the ‘absurdity’’ of exilii specie sepositos and observes that ‘Ausonius must be saying that the brothers were banished in fact, though not in name’’. Shackleton Bailey's solution is to replace exilii with bospitii, which gives excellent sense, but, even on the assumption of psychological error by a scribe, which is how Shackleton Bailey explains the corruption, may seem rather hard to credit. (...) An easier solution might be to write auxilii for exilii: in appearance Constantine's brothers were being helped and protected, in reality confined in exile. (shrink)

If one takes a course in philosophy to-day at a British university, a discreet silence is usually observed about existentialism. Often the professors understand little of its methods or its doctrine. If their excuse in part is the inaccessibility in English of standard existentialist texts, it is true also that philosophers trained in the “critical philosophy” now in vogue feel a certain aversion to existentialism or, at all events, to the notion they have formed of it. If Christianity was a (...) scandal to the Greeks and remains a scandal, as Dr. Brunner has recently told us, to contemporary humanists, existentialism is a scandal to the positivists. The latter are aware that the existentialists habitually trespass in the fields of religion, ethics, aesthetics and psychology, fields which, on the positivist view, should be reserved to other disciplines than philosophy, which has its own distinctive subject-matter and approach. They know that certain existentialists, notably Heidegger, provide a happy hunting ground for examples of “metaphysics.” They have heard that existentialism has sought to turn the tables on positivism by accusing it, if not of metaphysics, at all events of a barrenness of significant content, of a preoccupation with mere logistics which removes philosophy completely from men's business and bosoms. If the positivist accuses the existentialist of perpetrating “nonsense” in a technical sense, the latter retorts by accusing the positivist of reducing philosophy to nonsense in a pragmatic sense.

In the paper I offer a brief sketch of one of the sources of utilitarianism. Our biological ancestry is a matter of fact that is not altered by the way we describe ourselves. With philosophical theories it is otherwise. Utilitarianism can be described in ways that make it look as if it is as old as moral philosophy – as J. S. Mill thought it was. For my historical purposes, it is more useful to have an account that brings out (...) what is specific about Benthamism and its descendants. Let us try to make do with the following. First, utilitarianism asserts that the fundamental requirement of morality is that we are to maximize good, for everyone and not just for the agent. This basic principle presupposes that it makes sense to think of aggregating goods to make a total, and of comparing amounts of good thus aggregated. Second, the good to be brought about is located in feelings of pleasure, and the evil to be avoided in feelings of pain. These feelings have inherent value or disvalue regardless of how they are caused to exist and regardless of their own consequences. Third, all moral principles can be derived from the requirement that good be maximized. The principles involved in evaluating agents as well as in giving moral direction to action are nothing but applications of the basic principle. (shrink)

Reasoning under uncertainty, that is, making judgements with only partial knowledge, is a major theme in artificial intelligence. Professor Paris provides here an introduction to the mathematical foundations of the subject. It is suited for readers with some knowledge of undergraduate mathematics but is otherwise self-contained, collecting together the key results on the subject, and formalising within a unified framework the main contemporary approaches and assumptions. The author has concentrated on giving clear mathematical formulations, analyses, justifications and consequences of the (...) main theories about uncertain reasoning, so the book can serve as a textbook for beginners or as a starting point for further basic research into the subject. It will be welcomed by graduate students and research workers in logic, philosophy, and computer science as a textbook for beginners, a starting point for further basic research into the subject, and not least, an account of how mathematics and artificial intelligence can complement and enrich each other.

J. B. Schneewind's "The Invention of Autonomy" has been hailed as a major interpretation of modern moral thought. Schneewind's narrative, however, elides several serious interpretive issues, particularly in the transition from late medieval to early modern thought. This results in potentially distorted accounts of Thomas Aquinas, Hugo Grotius, and G. W. Leibniz. Since these thinkers play a crucial role in Schneewind's argument, uncertainty over their work calls into question at least some of Schneewind's larger agenda for the history of ethics.

One usually identifies a particular collection of geometric objects with the models of general relativity. But within this standard collection lurk ‘physically unreasonable’ models of spacetime. If such models are ruled out, attention can be restricted to some sub-collection of ‘physically reasonable’ models which can be considered a variant theory of general relativity. Since we have yet to identify a privileged sub-collection of ‘physically reasonable’ models, it is helpful to think of ‘general relativity’ in a pluralistic way; we can study (...) a collection of such ‘physically reasonable’ collections of models.
