M. H. A. Newman (1928) criticized Russell's structuralist philosophy of science. Demopoulos and Friedman have discussed Newman's critique, showing its relevance to the structuralist positions held by Schlick and Carnap, and to Putnam's argument against "metaphysical realism". I discuss Richard Braithwaite's (1940) appeal to Newman in a critique of Arthur Eddington. Braithwaite believed Newman had shown that "structure depends upon content". Eddington, in his reply, misunderstood the generality of Newman's argument.

Logical Options introduces the extensions and alternatives to classical logic which are most discussed in the philosophical literature: many-sorted logic, second-order logic, modal logics, intuitionistic logic, three-valued logic, fuzzy logic, and free logic. Each logic is introduced with a brief description of some aspect of its philosophical significance, and wherever possible semantic and proof methods are employed to facilitate comparison of the various systems. The book is designed to be useful for philosophy students and professional philosophers who have learned some (...) classical first-order logic and would like to learn about other logics important to their philosophical work.

It is well known that Tarski proved a result which can be stated roughly as: no sufficiently rich, consistent, classical language can contain its own truth definition. Tarski's way around this problem is to deal with two languages at a time, an object language for which we are defining truth and a metalanguage in which the definition occurs. An obvious question then is: under what conditions can we construct a definition of truth for a given object language. Tarski claims that (...) it is necessary and sufficient that the metalanguage be "essentially richer". Our contention, put bluntly, is that this claim deserves more scrutiny from philosophers than it usually gets and in fact is false unless "essentially richer" means nothing else than "sufficient to contain a truth definition for the object language.".

Michael Friedman has recently argued that Carnap'sLogical Syntax of Language is fundamentally flawed in a way that reveals the ultimate failure of logical positivism. Friedman's argument depends crucially on two claims: (1) that Carnap was committed to the view that there is a universal metalanguage and (2) that given what Carnap wanted from a metalanguage, in particular given that he wanted a definition of analytic for an object language, he was in fact committed to a hierarchy of stronger and stronger (...) metalanguages. We argue that neither of these claims need be accepted. We show that there is no textual evidence for (1) and that if metalanguages are to be used for merely descriptive and not also justificatory purposes, Carnap does not need to define analyticity sufficiently for proving consistency, and so could have given a definition that does not entail a hierarchy of metalanguages.

From recent writings of Brent Mundy and Michael Friedman we reconstruct two different representation-theoretic or embedding accounts of space-time relationalism, involving two different conditions on embeddings: respectively, uniqueness up to symmetry and uniqueness up to indistinguishability. We discuss the properties of these two accounts, and, with respect specifically to Friedman's projects, assess their merits and demerits.

RésuméCet article discute diverses confusions, actueles ou potentielles, liées á la bivalence et au tiers exclu. Il s'agit, en particulier, 1) d'examiner divers cas illustrant les rapports entre la bivalence et le tiers exclu ; 2) de discuter la thése selon laquelle le tiers exclu et le schéma-T de Tarskipour la vérité entraînent la bivalence; 3) de proposer quelques remarques sur les rapports entre la bivalence, le tiers exclu et la preuve par l'absurde; 4) de scruter un argument répandu selon (...) lequel le tiers exclu vaut pour les termes «précis» et 5) de commenter l'histoire de la terminologie. L'objectif ici est d'attirer l'attention des philosophes sur une distinction importante qui ne reçoit pas souvent le traitement minutieux qu'elle mérite. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXVI, Number 1, April 2000, pp. 129-142 Hume on ''Greatness of Soul" GRAHAM SOLOMON The "great-souled man" was first described in detail in Book iv of Aristotle's Nicomachean Ethics. Simon Blackburn concisely summarizes Aristotle's portrait of this "lofty character": "The great-souled man is of a distinguished situation, worthy of great things, 'an extreme in respect of the greatness of his claims, but a mean in respect (...) of the Tightness of them', perfectly virtuous, good at conferring benefits but ashamed of receiving them, neither humble nor vain. The combination involves proper pride or magnanimity." Such men will enter politics with the aim of preserving justice and working for the good of society, or they will exhibit great personal courage in battle, or, more generally, they will aim at virtuous action at all times, even when faced with painful choices and life-threatening circumstances. Historians disagree about whether Aristotle held that the great-souled man is motivated in part by a desire to be admired by others, but certainly he held that the great-souled man was capable of performing great and virtuous actions that would be admired.1 By the mid-eighteenth century, greatness of soul could be found in much less distinguished situations. Consider, for example, Laurence Sterne's Tristram Shandy. Tristram attributes greatness of soul to his mother for wanting to give birth to him under the care of a midwife rather than a doctor. His father thinks that turning down a large purse of money offered in exchange for naming one's son Judas is an act of greatness of mind. And Tristram says his friend Jenny exhibited greatness of soul by purchasing a much less expensive piece of silk than the one she initially wanted, deferring to Tristram's unvoiced but Graham Solomon is at the Philosophy Department,Wilfrid Laurier University,Waterloo, Ontario, Canada N2L 3C5. e-mail: [email protected] 130 Graham Solomon obvious judgment.2 For an example from the nineteenth century, consider the following passage from the novel The Wrecker (1891) by Robert Louis Stevenson and Lloyd Osbourne. The narrator, a wealthy young American, is slumming as a bohemian art student in the Latin Quarter of Paris: "I always looked with awful envy... on a certain countryman of my own, who had a studio in the Rue Monsieur Ie Prince, wore boots, and long hair in a net, and could be seen tramping off, in this guise, to the worst eating-house of the quarter, followed by a Corsican model, his mistress, in the conspicuous costume of her race and calling. It takes some greatness of soul to carry even folly to such heights as these."3 There the character's greatness of soul seems to involve an ability to ignore or overlook or misinterpret the opinions others might have of him. While the phrase "greatness of soul" or "greatness of mind" is not commonly used nowadays,4 the Latin form "magnanimity" is still in use in ordinary, everyday, reasonably educated discourse. And occasionally "highmindedness " is used. The capacity to make magnanimous gestures is still widely felt to be a virtue. "Magnanimity" nowadays refers to a mix of unselfishness, generosity, the capacity to rise above petty feelings of resentment and revenge, and more generally and vaguely to a kind of nobility of heart and mind. These are features that Aristotle would recognize. But, it seems to me, we are prepared to apply the term to a far wider class of people than Aristotle would. Magnanimity is nowadays thought to be a virtue that can be exhibited by almost anyone. The first extended discussion in English-language philosophy of the concept of greatness of soul or mind is in David Hume's Treatise III iii 2, a section titled "Of greatness of mind." Hume's discussion contributed to a domesticated and democratized understanding of the concept, a more serious ancestor of the concept found in Tristram Shandy5 and The Wrecker. Donald Siebert argues in the chapter "In Search of the Hero of Feeling" in The Moral Animus of David Hume6 that after the initial exploration of the concept in the Treatise, Hume eventually settled in The History...

We discuss in this paper the question of the scope of the principle of tolerance about languages promoted in Carnap's The Logical Syntax of Language and the nature of the analogy between it and the rudimentary conventionalism purportedly exhibited in the work of Poincaré and Hilbert. We take it more or less for granted that Poincaré and Hilbert do argue for conventionalism. We begin by sketching Coffa's historical account, which suggests that tolerance be interpreted as a conventionalism that allows us (...) complete freedom to select whatever language we wish—an interpretation that generalizes the conventionalism promoted by Poincaré and Hilbert which allows us complete freedom to select whatever axiom system we wish for geometry. We argue that such an interpretation saddles Carnap with a theory of meaning that has unhappy consequences, a theory we believe he did not hold. We suggest that the principle of linguistic tolerance in fact has a more limited scope; but within that scope the analogy between tolerance and geometric conventionalism is quite tight. (shrink)

We show that four central aspects of Hume's account of cause were contained and available to him in the translation of Sextus Empiricus' "Outlines of Pyrrhonism" contained in Thomas Stanley's 1687 _History of Philosophy.

In lieu of an abstract, here is a brief excerpt of the content:Some Sources for Hume's Opening Remarks to Treatise LIVJII Graham Solomon Hume opens Book I, Part IV, Section III of the Treatise with these remarks: Several moralists have recommended it as an excellent method ofbecoming acquainted with our own hearts, and knowing our progress in virtue, to recollect our dreams in a morning, and examine them with the same rigour, that we wou'd our most serious and deliberate actions. (...) Our character is the same throughout, say they, and appears best where artifice, fear, and policy have no place, and men can neither be hypocrites with themselves nor others. The generosity, or baseness of our temper, our meekness or cruelty, our courage or pusilanimity, influence the fictions of the imagination with the most unbounded liberty, and discover themselves in the mostglaring colours. Who were these moralists? One looks in vain in the work of Malebranche, Locke, Shaftesbury and Hutcheson for such a recommendation. Did anyone make that recommendation? One moralist who did was "John Shadow," in a letter to Joseph Addison published in The Spectator, no. 586, 27 August 1714. Addison introduces Shadow's letter with the remark that it "is built upon a thought that is new, and very well carried on; for which Reasons I shall give it to the Publick without Alteration, Addition, or Amendment." I quote at length, for easy comparison with Hume: Sir, It was a good Piece of Advice which Pythagoras gave to his Scholars. That every Night before they slept they should examine what theyhad been a doing that Day, and so discover what Actions were worthy of Pursuit to Morrow, and what little Vices were to be prevented from slipping unawares into a Habit. If I might second the Philosopher's Advice, it should be mine, That in a morning before my Scholar rose, he should consider what he had been about that Night, and with the Volume XVI Number 1 57 GRAHAM SOLOMON same Strictness, as if the Condition, he has believed himself to be in, was real. Such a Scrutiny into the Actions ofhis Fancy must be of considerable Advantage, for this Reason, Because the Circumstances which a Man imagines himself in during Sleep, are generally such as entirely favour his Inclinations good or bad, and give him imaginary Opportunities of pursuingthem to the utmost; so thathis Temper will lye fairly open to his View, while he considers howitis moved when free from those Constraints which the Accidents ofreal Life put it under. Dreams are certainly the Result of our waking Thoughts, and our daily Hopes and Fears are what give the mind such nimble Relishes of Pleasure, and such severe Touches ofPain, in its Midnight Rambles. AMan that murders his Enemy, or deserts his Friend in a Dream, had need to guard his Temper against Revenge and Ingratitude, and take heed that he be not tempted to do a vile thing in Pursuit of false, or the Neglect of true Honour... I think it has been observed in the Course of your Papers, how much one's Happiness or Misery may depend upon the Imagination: ofwhich Truth those strange Workings ofFancy in Sleep are no inconsiderable Instances; so that not only the Advantage a Man has ofmaking Discoveries ofhimself, but a Regard to his own Ease or Disquiet, may induce him to accept ofmy Advice... Shadow has been identified as the poet John Byrom by various of the later editors of The Spectator? Of these, D. F. Bond footnotes Byrom's reference to Pythagoras, noting the publication in English of André Dacier's The Life ofPythagoras, with his Symbolism and Golden Verses; together with the Life ofHierocles, and his Commentaries upon the Verses. Bond notes Hierodes' comments on the following Verses: Never suffer Sleep to close thy Eye-lids, after thy going to Bed, Till thou hast examin'd by thy Reason all thy Actions of the Day Wherein have I done amiss? What have I done? What have I omitted that I ought to have done? If in this Examination, thou find that thou hast done amiss, reprimand thy self severely for it: And if thou has done any Good, rejoice. Dacier cites Porphyry and Marcus Aurelius... (shrink)
