What Aphorism Does Nietzsche Explicate in Genealogy of Morals, Essay III ? JOHN T. WILCOX A picture held us captive. Wittgenstein ~ AS EVERYONE KNOWS, the dominant opinion is not always correct. Current scholarship, in all likelihood, makes assumptions which have not yet been questioned; and probably some of them will be seen to be false, once they have been examined. I will argue here that there is a dominant but erroneous assumption concerning the Third Essay in Nietzsche's On (...) the Genealogy of Morals. It will be obvious that correcting this error has some serious implica- tions for almost all current interpretations of the essay. After acknowledging, at the end of his Preface to the Genealogy, that some might find his new book "incomprehensible," Nietzsche warns that "the fault.., is not necessarily mine." He assumes, he says, that readers have already worked hard at his earlier writings, themselves "not easy to pene- trate," and have been "wounded" and "delighted" by his Zarathustra. Then he begins one of several passages we must examine carefully: In other cases, people have difficulty with the aphoristic form: this arises from the fact that today this form is not taken seriously enough. An aphorism, properly stamped and molded, has not been "deciphered" when it has simply been read; rather, one has then to begin its exegesis, for which is required an art of exegesis. I have offered in the third essay of the present book an example of what I.. (shrink)

Despite the fact that six years have passed since 9/11, the Pentagon's recent decision to try six Guantanamo detainees for capital crimes such as terrorism and support of terrorism made national headlines. William Glaberson, "U.S. Charges 6 With Key Roles in 9/11 Attacks", N.Y. Times, Feb. 11, 2008, at A1. In this Debate, Professors Amos N. Guiora, of the University of Utah, and John T. Parry, of Lewis & Clark Law School, attempt to settle the question of what sort (...) of forum is most appropriate to try the thousands of individuals in U.S. custody who are suspected of terrorism. Professor Guiora considers three forum options: treaty-based international terror courts, traditional Article III courts, and a hybrid option he calls domestic terror courts. Ultimately, Professor Guiora argues in favor of domestic terror courts, which he describes as being able to balance the legitimate rights of the individual with the equally legitimate national security rights of the state. He considers this option to be the most practical and expedient policy solution, necessitated by an untenable tension between the understanding that some of the detainees present a genuine threat to American national security, and an awareness that indefinite detention violates constitutional principles and fundamental concepts of morality. Professor Parry agrees that current U.S. policy toward detainees has been misguided, but does not believe that innovations of the sort proposed by Professor Guiora are necessary. Rather, he suggests that policymakers should choose Article III courts rather than hybrid courts for trials of suspected terrorists, with military courts as a fallback option. Professor Parry points to research that shows that the federal government is often able to prosecute suspected terrorists in federal court, and therefore considers alternative proposals to Article III courts to be solution[s] in search of a problem. Professor Parry realizes that trial in federal court will not be possible for every suspected terrorist, and concludes that, [f]or people who pose a risk but whose conduct may not violate federal criminal law, prolonged preventive detention is the best choice.

In lieu of an abstract, here is a brief excerpt of the content:The Background Theory of Delusion and Existential PhenomenologyRichard G. T. Gipps (bio) and John Rhodes (bio)KeywordsPhenomenology, psychological explanation, epistemology, schizophreniaSituating and Clarifying the PaperThe commentaries of Nassir Ghaemi and Giovanni Stanghellini help to sketch out the intellectual landscape of philosophical perspectives in psychiatry, and situate our paper within it. A happy convergence between the analytical philosophy perspective from which we were writing, and the existential–phenomenological paradigm described by (...) both authors, is the result. Stanghellini in particular carefully describes three main theories of existential deformations, tracing delusion formation back to either (i) a disturbance of meaning synthesis conceived as a dysfunction of a Husserlian consciousness, (ii) a disturbance of pre-reflective self-consciousness resulting in a kind of paralyzing hyperreflexivity, and (iii) (Stanghellini’s preferred model) a disturbance of embodiment. This final account views delusion as springing from a failure in the subject’s corporeal and praxical being-in-the-world. As the subject’s practical, pre-reflective grip on the world is loosened, so their minds become unconstrained by that understanding and practical rationality immanent within that grip, and thought, now unconstrained, starts to travel through delusional worlds. Stanghellini accordingly views our model as an example of a disembodiment theory, which allows it to overcome the disadvantages of the first two models, which may both, in their own ways, overvalue the rôle of (disturbances of) reflective consciousness in the formation (and delusional deformation) of everyday understanding.Being situated within a preexisting landscape has both its benefits and its disbenefits, the principle example of the latter being the potential assimilation of anything new to what has already been said. Thus, although we are grateful to our commentators for placing us on the larger historical and conceptual map, it may be helpful to briefly rehearse our motivations for drawing on the philosophical ideas of the Bedrock and Background in our theory of delusion. Our paper was primarily motivated by a concern that current, psychologically mainstream, cognitive models of delusion, although helpfully drawing our attention to common reasoning and perceptual deficits in the person with psychosis, fail to adequately account for what is delusional about delusions. It was, in [End Page 321] particular, to account for the certainty with which the deluded person clings to often quite extraordinary beliefs that we drew on the epistemological notion of the background. And although this epistemological notion fits quite neatly with ontological concerns regarding the embodied and praxical character of human existence, it is the particular epistemic rôle that it played in our theory—to do with the extraratiocinative constraint on judgement provided by the Background—that we wish to stress here.We return to this shortly, but first wish to comment briefly on two specific considerations raised by the commentaries. The first concerns Stanghellini’s claim that, for us, “when studying delusions, the focus should be on providing an adequate framework for understanding, rather than providing empirical hypotheses to be tested” (2008, 311–314). It seems to us, however, that both are equally important. What we wished to stress, however, was that empirical hypothesis testing may be led astray if it is not informed by an adequate framework for understanding. For example, most cognitive psychological experiments on delusions concern themselves with the individual’s ability to make appropriate guesses (e.g., regarding the color of beads in a bag), and their tendency to jump to conclusions; they do not concern themselves with the kinds of extraordinary conviction and certainty met with in delusion. The risk run by empirical researchers of cognitive factors in delusion is that a lack of a prior adequate theorization of delusion makes for accounts that are ultimately only of the formation, not of delusion in particular but rather of false or unusual beliefs more generally. An analytical approach, however, can help to explicate the ways in which the psychiatric concept of delusion fails to be adequately characterized by the quite general ‘external criteria’ of delusion (as Jaspers [1963] called them: falsity, stubbornness, uncommon), and aids in the construction of empirical hypotheses this time constrained by an understanding of the true ‘internal criteria’ of psychotic belief. Such an approach helps to spell out the... (shrink)

Automated reasoning about uncertain knowledge has many applications. One difficulty when developing such systems is the lack of a completely satisfactory integration of logic and probability. We address this problem directly. Expressive languages like higher-order logic are ideally suited for representing and reasoning about structured knowledge. Uncertain knowledge can be modeled by using graded probabilities rather than binary truth-values. The main technical problem studied in this paper is the following: Given a set of sentences, each having some probability of being (...) true, what probability should be ascribed to other (query) sentences? A natural wish-list, among others, is that the probability distribution (i) is consistent with the knowledge base, (ii) allows for a consistent inference procedure and in particular (iii) reduces to deductive logic in the limit of probabilities being 0 and 1, (iv) allows (Bayesian) inductive reasoning and (v) learning in the limit and in particular (vi) allows confirmation of universally quantified hypotheses/sentences. We translate this wish-list into technical requirements for a prior probability and show that probabilities satisfying all our criteria exist. We also give explicit constructions and several general characterizations of probabilities that satisfy some or all of the criteria and various (counter) examples. We also derive necessary and sufficient conditions for extending beliefs about finitely many sentences to suitable probabilities over all sentences, and in particular least dogmatic or least biased ones. We conclude with a brief outlook on how the developed theory might be used and approximated in autonomous reasoning agents. Our theory is a step towards a globally consistent and empirically satisfactory unification of probability and logic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE FAILURE OF HUME'S TREATISE The Treatise is, of course, a failure; Hume tells us so himself. Hume's reservations about the Treatise both in later writings and even within the work itself are well known. What is less clear is exactly why Hume found the Treatise so unsatisfactory. This is a complicated question, for to explain why the Treatise does not live up to Hume's expectations presupposes an understanding (...) of the more fundamental problem of what Hume's expectations were in the first place. In what follows I present a theory about what it was that Hume hoped to accomplish in the Treatise and why this project was ultimately unsuccessful. In the first two sections of this paper I discuss three philosophical positions with which Hume was concerned, and I present three faculties of the understanding which he isolates in the Treatise. In the third section I argue that Hume's goal is to match these three philosophical positions with the three faculties, and by doing so to provide both a critique of unsatisfactory positions and a foundation for his own "science of man." I conclude by showing that this matching project is ultimately unsuccessful, thus dooming the Treatise to at least partial failure. My analysis is based primarily on Treatise I; without argument here I subscribe to Kemp Smith's thesis that Treatise I represents the most advanced stage of thinking in the 2 Treatise. This explains to me how Hume can continue to write Books II and III after the partial failure of the project which he registers in the conclusion of Treatise I. I read the conclusion to Book I as the conclusion of the whole project. Three Philosophical Positions The three philosophical positions which I wish to discuss are described by Hume at one point as that of the vulgar, that of a false philosophy, and that of the true (T222). 58. Let us discuss them in that order: 1.Vulgar Superstition. Hume frequently discusses and criticizes a set of beliefs and ways of thinking which for convenience I call "vulgar superstition." The real enemy here is popular religion, which for Hume is the clearest expression of this mode of thought. In the Treatise Hume is more wary of criticizing popular religion than he sometimes was in later works, but the general target of his remarks is still clear. The kinds of thought Hume has in mind here are bigotry, superstition, credulity, prejudice, and indoctrination. This type of thinking presents a constant barrier to human enlightenment and progress, and for Hume the role of philosophy is to attack superstition and keep it in check. As Hume expressed it a few years later, One considerable advantage that arises from philosophy, consists in the sovereign antidote which it offers to superstition and false religion. All other remedies against that pestilent distemper are vague, or at least uncertain. 2.Dogmatism. Another target which Hume attacks in the Treatise is a dogmatic or rationalistic approach to philosophy, best exemplified by Cambridge Platonism and Cartesianism. This type of philosophy seeks to base ethics upon pure reason, to know things with certainty, and to penetrate the ultimate nature of man, God, and the universe. Hume hopes to show the fallacy of all this philosophy (T 413) by showing that reason can never motivate action, that only fools claim to know things with certainty (T 270), and that we must be content to understand the appearance of things rather than to know their secret causes (T 64). 3.The Science of Man. Hume's own position, the "science of man," is presented as a middle ground-empirical rather than a priori and scientific rather than superstitious. The goal of this true philosophy is to discover the original qualities of human nature (T 562), resulting in a Newtonian analysis of man himself. For Hume true philosophers are characterized by their moderate scepticism (T 224), so Hume's system is to be built on probable judgments rather than certain ones, and it will deal with appearances rather than essences. Here again Hume follows the "constructive scepticism" of Newton. Hume sees considerable danger in following either rationalism or superstition, but he has great... (shrink)

Schanz never edited either the Parmenides or the Philebus. For the former we have minute collations of B and T in Waddell's edition, but the readings of W are still unknown. As, however, Wilamowitz has no suggestions to make about the text of the Parmenides, this does not matter for our present purpose. It seems that this dialogue was transcribed with special care just because of its difficulty. At any rate, its text is remarkably good. For the Philebus I published (...) the readings of T for the first time, and I have now procured a photograph of W in this dialogue from Vienna. Mr. R. G. Bury's edition was an anachronism. Though he published it in 1897, he had apparently never heard of the manuscript T. In his note entitled The Text of the Philebus he attributes to Schanz a view of the relation between the MSS. which that editor had recanted just twenty years earlier. Except for a few corrections regarding the readings of B , Mr. Bury's own apparatus criticus is merely a reprint of Bekker's, which was published in 1823. For the Symposium we have Schoene's collation of W, which I was able to use in my second edition, and I have now a photograph of that MS. in the Phaedrus too. (shrink)

I try in this essay to accomplish two things. First I offer some first thoughts toward a clarification of the ethical foundations of private property rights that avoids pitfalls common to more strictly Lockean theories, and is thus better prepared to address arguments posed by critics of standard private property arrangements. Second, I'll address one critical argument that has become pretty common over the years. While versions of the argument can be traced back at least to Pierre Joseph Proudhon, I'll (...) focus on a formulation given it by Jeremy Waldron. The basic idea is that the only sound arguments for private property rights lead to the conclusion that society has an obligation to insure that every citizen possess private property. In Waldron's formulation, what is justifiable is a general, rather than a special, right to private property. I shall try to suggest that this conclusion is unwarranted. (shrink)

Recent literature in epistemology has focused on the following argument for skepticism (SA): I know that I have two hands only if I know that I am not a handless brain in a vat. But I don't know I am not a handless brain in a vat. Therefore, I don't know that I have two hands. Part I of this article reviews two responses to skepticism that emerged in the 1980s and 1990s: sensitivity theories and attributor contextualism. Part II considers (...) the more recent ‘neo-Moorean’ response to skepticism and its development in ‘safety’ theories of knowledge. Part III argues that the skeptical argument set out in SA is not of central importance. Specifically, SA is parasitic on skeptical reasoning that is more powerful and more fundamental than that displayed by SA itself. Finally, Part IV reviews a Pyrrhonian argument for skepticism that is not well captured by SA, and considers a promising strategy for responding to it. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUME, MOTIVATION AND MORALITY Hume remarks, in the Abstract, that his account of the passions in Book II of the Treatise has 'laid the foundation' (A 7 Ì1 for his theory of morals. Pall Ardal has shown how Hume's theory of certain indirect passions (pride, humility, love, hatred) underpins his theory of the evaluation of character. I propose to explore the links between Hume's account of motivation and his (...) treatment of an agent 'ß moral assessment of prospective action. Where Ardal stresses the moral spectator, my focus is on the agent. Hume himself attends primarily to the moral spectator, but the agent's perspective is central in two of his chief arguments concerning morals, that for the thesis that moral distinctions are derived from a moral sense, and that for the artificiality of justice. I shall take it that the argument of Treatise II, iii, 3 ("Of the influencing motives of the will") provides the framework for analysis: acting for moral reasons is like acting for any other reason; citing his moral principles to explain a man's actions is like citing his desire to preserve his health as an explanation of his taking exercise; deliberating about moral matters is like pondering the purchase of a pair of shoes. Of course there are differences; I shall look to them shortly. It is essential, however, to begin with the similarities. To a first approximation, the central doctrine is that the reasons that explain actions are rational causes of those actions. Reasons for actions are constituted by suitably related desires and beliefs; volitions are somehow implicated in intentional actions. Reasons are causes: the desires and beliefs that constitute reasons cause volitions, and thus actions. They are rational causes: there are links of special kinds between the contents of the desires and beliefs that constitute an agent's reasons for what he does, and the content of the volitions implicated in the actions done. Hume is at pains to deny that "reason [here: belief] alone can... be a motive to any action of the will" (T 413). But he insists there are "two principal parts [of human nature], which are requisite in all its actions, the affections and understanding' (T 493). I suggest that by "affections" he here means specifically (if broadly) desires, and so both the "direct passions" of desire and aversion and such "indirect passions" as benevolence, anger, pity, compassion and malice. Hume's official doctrines both of desires and of volitions are unsatisfactory as they stand; he treats each as simple impressions. To be sure, these simple impressions are said always to be accompanied by thoughts of (in Hume's phrase) their objects. Even such complex states, however, can play no satisfactory role in psychological theory. The insights that Hume's official doctrines mishandle can, I suggest, be incorporated into more defensible, and more-or-less Humean, analyses of the internal structure of desire and volition. Having made efforts along these lines elsewhere, however, I shall here concentrate on other features of desire and volition that are germane to Hume's moral psychology. Desires and volitions are alike in two linked respects, among others: neither takes a truth value (and so each differs from belief); each is a conative, not a cognitive, psychological state (and so, again, each differs from belief). Because desires and volitions are not capable of "an agreement or disagreement either to the real relations of ideas, or to real existence and matter of fact" it is "impossible... they can be pronounced either true or false" (T 458). Their general functional role is that of "propense and averse motions of the mind" (T 574). To be sure, there are differences. The principal difference is that of specific functional location: desires are constituents in reasons for acting: volitions are constituents of (or otherwise implicated in) actions done for such reasons. This functional difference is tied to differences of content. To grasp the many relations among belief, desire and volition, when the first two serve as 4 reason for (and so cause of) the third, it is useful to plot their causal relations onto the elements in an Aristotelian practical syllogism. Desires function as causally salient major premises... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:F. H. Bradley and the Working-out of Absolute Idealism* JOHN HERMAN RANDALL, JR. FRANCIS HERBERTBRADLEY (1846-1924) 1 agreed with the other English idealists that the real world is the experienced world. But he started with the fundamental conviction that "experience" is more than "thought," as Green had maintained. Bradley's basic drive is the refusal to abolish "feeling" in favor of knowledge and intelligibility. "Feeling" is a fundamental and (...) ineradicable aspect of "reality"m more fundamental, in fact, than thinking. In the immediately experienced world, all intelligible distinctions and relations are merged in a "whole of feeling" which is the ultimate subject-matter of philosophy. "Thought" arises out of feeling, out of "immediacy," as an interpretation of immediate experience by distinguishing relations and aspects in it. "Knowledge " is only one aspect of the experienced world; it needs blending with "feeling" and will to include all the experienced aspects. "Feeling" starts for Bradley, in his Principles of Logic (1883), in pretty much the empiricist sense, as isolated sensations, and as subjective (in flavor at least). It then becomes neutral: "feeling" is identified with "the felt"; and it grows richer, attempting to include the whole wealth of immediate experience. Thus Bradley gets very close to Dewey's conception of "direct experience," "non-reflective experience," without, however, Dewey's biological analysis. It is through this conception of experience that Bradley approaches the naturalism to which his thinking almost arrived at the end. Thought, that is, has a setting in experience " it is relational, and by its analysis it breaks up experienced and felt wholes. There is a double insistence in Bradley. On the one hand, reality is experienced, but is not adequately expressed in thought. On the other, reality/s accessible to knowledge. What has often been called Bradley's "skepticism" is really an objective relativism. Thought, logical structure, is not ultimate. In Appearance and *This study of F. It. Bradley is based on one of five chapters on post-ttegehan philosophical Ideahsm in Britain and America to be included in my forthcoming Career oJ Philosophy in Modem Times, Vol.III: The Hundred Years Since Darwin. ISee Bradley ed. of Mind, XXXIV (1925); A. E. Taylor, "F. H. Bradley"; J. H. Muirhead, "Bradley's Place in Philosophy." See also T. M. Forsyth, English Philosophy (London: 1910), chap. VII, 2rid part; Rudolf Kagey, F. H. Bradley's Logic (New York: 1931). The best philosophical analyses of Bradley are Robert D. Mack, The Appeal to Immediate Experience (New York: 1945),and Richard Wollheim,F. H. Bradley (Pelican Books, 1959). [245] 246 HISTORY OF PHILOSOPHY Reality, he insists it is really self-contradictory; then later he emphasizes rather that it is always relative to its particular subiect-matter. The real, experienced world is never identical with the intelligible world, yet it is also never "extraneous " to it. The relation of the two can be said to be, in Aristotelian terms, that of substance to form, that of what is to its intelligible aspect. The intelligible world, the system of science and knowledge, thus fundamentally needs criticism in the light of its setting in the experienced world. This is not only the entire drive of Dewey's Experience and Nature; it is the expression of that whole current of thought on the Continent which began with the criticism of Hegel's "panlogism" in the 1840's and is today called "Existentialism." Bradley is the British counterpart of all those who have criticized philosophies of logical structure like T. H. Green's, or like the other contemporary forms of Neo-Kantianism in Germany and France. The "known world" is a world of relations distingflished in the richer "real world." These distinctions are ultimately relative to their particular setting, but in that setting they are valid enough. Bradley's celebrated doctrine of the "degrees of truth and reality" means that practically knowledge is "true"; any idea which fulfills its purpose of rendering some portion or aspect of experience intelligible and significant and meaningful, and which is not ousted by a better idea, Bradley is willing to say is "so far true." It is valid, in its own sphere and purpose, despite its ultimate inconsistency; the wave-theory... (shrink)

As befits a French philosopher of the 1960s, Gilles Deleuze (1925-995), was famous for his antihumanism and his anti-essentialism. Humans are fully part of nature with no supernatural supplement; and essences are not the way to individuate things. That doesn’t seem to leave much room for a Deleuzean human nature, but that’s what I want to try to explore. I’ll take my clue from what he says in A Thousand Plateaus about nomads, who “reterritorialize on their power of deterritorialization.” In (...) other words, they are most at home when on the move. But this isn’t just spatial movement; we can also say that the habit of nomads is to break habits. I’ll make sense of this claim by referring to Bruce Wexler’s Brain and Culture (MIT, 2006), in particular, his claim that humans evolved for a lengthy childhood period of socially mediated neuroplasticity. Human nature on this view is such that we are individuated by our singular patterns of social – somatic interaction. And this in turn is “nomadic” in Deleuze’s sense: our nature is to be so open to our nurture that it becomes second nature. That is, we’re at home wherever home is. There’s an anti-essentialist nuance here, however. It’s children who are most “nomadic,” most plastic. Most adults drift away from nomadism and become sedentary: they want more of the same. But even here we must nuance things: what if “more of the same” means “more change”? In other words, are there adult “nomads”? I think there are. But we’ll need to discuss Deleuze’s ontology first in order to make sense of these claims. Deleuze is an interactive process philosopher: we aren't substances but processes and those processes are not individuated by properties but as singular patterns of social and somatic interaction. The embodied and the embedded aspects of our being intersect – we are bodies whose capacities form in social interaction. And it's in this intersection of the social and the somatic that subjectivity and selfhood emerge – and are sometimes attenuated and even bypassed.. (shrink)

In this essay I’d like to help readers prepare to learn from Gilles Deleuze’s Difference and Repetition.1 Such an essay is needed, as truer words were never spoken than when Deleuze said of it in his "Letter to a Harsh Critic": "it's still full of academic elements, it's heavy going"2 Now part of the “academic” aspect of the work comes from Deleuze having submitted Difference and Repetition to his jury as the primary thesis for the doctorat d'Etat in 1968.3 But (...) that doesn’t lessen the need for help when first approaching the book. The context of Deleuze’s remarks in his “Letter” should be noted: he has just been noting that "the history of philosophy plays a patently repressive role in philosophy, it's philosophy's own version of the Oedipus complex."4 Deleuze continues that he tried to subvert this repressive function by various means. First, by writing on authors such as Lucretius, Hume, Spinoza and Nietzsche who contested the rationalist tradition by the "critique of negativity, the cultivation of joy, the hatred of interiority, the externality of forces and relations, the denunciation of power [pouvoir]." Second, and quite notoriously, by “a sort of buggery [enculage] or (it comes to the same thing) immaculate conception.” That is, by making the author say something in their own words that would be “monstrous.”5 These are famous lines, and the last is certainly amusing in an épater les bourgeois sort of way. But what's really important in my view comes next, when Deleuze explains what it means to finally write "in your own name," as he claims he first did in Difference and Repetition. (shrink)

Hrushovski originated the study of “flat” stable structures in constructing a new strongly minimal set and a stable 0-categorical pseudoplane. We exhibit a set of axioms which for collections of finite structure with dimension function δ give rise to stable generic models. In addition to the Hrushovski examples, this formalization includes Baldwin's almost strongly minimal non-Desarguesian projective plane and several others. We develop the new case where finite sets may have infinite closures with respect to the dimension function δ. In (...) particular, the generic structure need not be ω-saturated and so the argument for stability is significantly more complicated. We further show that these structures are “flat” and do not interpret a group. (shrink)

We give a general account of the goals of axiomatization, introducing a variant on Detlefsen’s notion of ‘complete descriptive axiomatization’. We describe how distinctions between the Greek and modern view of number, magnitude, and proportion impact the interpretation of Hilbert’s axiomatization of geometry. We argue, as did Hilbert, that Euclid’s propositions concerning polygons, area, and similar triangles are derivable from Hilbert’s first-order axioms. We argue that Hilbert’s axioms including continuity show much more than the geometrical propositions of Euclid’s theorems and (...) thus are an immodest complete descriptive axiomatization of that subject.

We explore Shelah's model‐theoretic dividing line methodology. In particular, we discuss how problems in model theory motivated new techniques in model theory, for example classifying theories by their potential (consistently with Zermelo–Fraenkel set theory with the axiom of choice (ZFC)) spectrum of cardinals in which there is a universal model. Two other examples are the study (with Malliaris) of the Keisler order leading to a new ZFC result on cardinal invariants and attempts to clarify the “main gap” by reducing the (...) dependence of certain versions on (highly independent) cardinal arithmetic.

In this paper we study abstract elementary classes of modules. We give several characterizations of when the class of modules A with is abstract elementary class with respect to the notion that M1 is a strong submodel M2 if the quotient remains in the given class.

We study when classes can have the disjoint amalgamation property for a proper initial segment of cardinals. Theorem A For every natural number k, there is a class $K_k $ defined by a sentence in $L_{\omega 1.\omega } $ that has no models of cardinality greater than $ \supset _{k - 1} $ , but $K_k $ has the disjoint amalgamation property on models of cardinality less than or equal to $\mathfrak{N}_{k - 3} $ and has models of cardinality $\mathfrak{N}_{k (...) - 1} $ . More strongly, we can have disjoint amalgamation up to $\mathfrak{N}_\alpha $ for α > ω, but have a bound on size of models. Theorem B For every countable ordinal a, there is a class $K_\alpha $ defined by a sentence in $L_{\omega 1.\omega } $ that has no models of cardinality greater than $ \supset _{\omega 1} $ , but K does have the disjoint amalgamation property on models of cardinality less than or equal to $\mathfrak{N}_\alpha $ . Finally we show that we can extend the $\mathfrak{N}_\alpha $ to $ \supset _\alpha $ in the second theorem consistently with ZFC and while having $\mathfrak{N}_i \ll \supset _i $ for 0 > i < α. Similar results hold for arbitrary ordinals α with |α|= K and $L_{k + ,\omega } $. (shrink)

We prove two results on the stability spectrum for Lω1,ω. Here [Formula: see text] denotes an appropriate notion of Stone space of m-types over M. Theorem for unstable case: Suppose that for some positive integer m and for every α μ, K is not i-stable in μ. These results provide a new kind of sufficient condition for the unstable case and shed some light on the spectrum of strictly stable theories in this context. The methods avoid the use of compactness (...) in the theory under study. In this paper, we expound the construction of tree indiscernibles for sentences of Lω1,ω. Further we provide some context for a number of variants on the Ehrenfeucht–Mostowski construction. (shrink)

In Part I of this paper we argued that the first-order systems HP5 and EG are modest complete descriptive axiomatization of most of Euclidean geometry. In this paper we discuss two further modest complete descriptive axiomatizations: Tarksi’s for Cartesian geometry and new systems for adding $$\pi$$. In contrast we find Hilbert’s full second-order system immodest for geometrical purposes but appropriate as a foundation for mathematical analysis.

We provide a general framework for studying the expansion of strongly minimal sets by adding additional relations in the style of Hrushovski. We introduce a notion of separation of quantifiers which is a condition on the class of expansions of finitely generated models for the expanded theory to have a countable ω-saturated model. We apply these results to construct for each sufficiently fast growing finite-to-one function μ from 'primitive extensions' to the natural numbers a theory T μ of an expansion (...) of an algebraically closed field which has Morley rank 2. Finally, we show that if μ is not finite-to-one the theory may not be ω-stable. (shrink)

It is shown (i) that causation exists, since we couldn't even ask whether causation existed unless it did; (ii) that any given case of causation is a case of persistence; and (iii) that spatiotemporal relations supervene on causal relations. (ii) is subject to the qualification that we tend not to become aware of instances of causation as such except when two different causal lines---i.e. two different cases of persistence---intersect, resulting in a breakdown of some other case of persistence, this being (...) why we tend to regard instances of causation as fundamentally disruptive, as opposed to preservative in nature. The meaning of (iii) is that spatiotemporal relations are causal relations considered in abstraction of the various specific differences holding between different kinds of causation. (shrink)

Empiricism is the doctrine that all knowledge has a strictly observational basis. Rationalism is the doctrine that least some knowledge has non-observational, purely conceptual basis. In the present work, empiricism is carefully considered and found to have four dire shortcomings: -/- (1) Empiricism cannot account for our knowledge of what doesn't exist, let alone what cannot exist. -/- (2) Empiricism cannot account for our knowledge of dependence-relations, given (1), coupled with the fact that 'P depends on Q' is equivalent with (...) 'not-Q either necessitates or is dispositive of not-P.' -/- (3) Empiricism cannot account for our knowledge of the past, the future, or the possible, given (2), coupled with the fact knowledge of any of these domains requires knowledge of conditional truths (truths of the form "if P, then Q") and therefore of dependence-relations. -/- (4) Empiricism cannot by itself apprise us of any truths, given (3), coupled with the fact that knowledge of conditional truths is necessary to recognize the truths implicit in any body of sensory data. -/- The arguments of key empiricists are closely examined. Special attention is paid to George Berkeley's arguments for idealism ('to be is to be perceive/conceived'). It is shown that, although Berkeley's arguments fail, profound insights are embedded in the very sophisms that vitiate those same arguments, the three most important ones being: -/- (i) That data-modelling and truth-identification at least sometimes coalesce, -/- (ii) That scientific theories are at least sometimes capable of being represented as interpreted formal calculi, and -/- (iii) That when theoretical terms are defined contextually, as opposed to directly, otherwise unintelligible assertions acquire scientific significance. -/- Further, it is shown that, even though Berkeley's arguments for idealism fall through, he himself deserves credit for identifying the principle in terms of which the fallacies in those arguments are to be understood, namely: -/- (*) It is not sensory experience alone that yields awareness of the outside world, but sensory experience coupled with awareness on the subject's part of relational invariances holding among the objects of those awareness. -/- Thus, perceptual knowledge is knowledge of invariances. And, to make a point hinted at in Berkeley's work, knowledge of laws is meta-perceptual knowledge, given that laws of nature are invariances holding among the invariances holding among the objects of perception.

In the first part of this two-part work, the economics of higher education are explained. It is made clear how a university’s business model differs from that of a company that has to compete on the open market. On this basis, it is explained: -/- (i)Why universities are in no way threatened by low retention-rates and graduation-rates; (ii)Why universities cannot significantly improve or otherwise alter the quality of their educational services without imperiling their very existences; (iii)Why universities do not have (...) to improve the quality of their educational services; (iv)Why universities couldn’t improve the quality of their services even if they wanted to; (v)Why the fact that many universities have low retention- and graduation-rates does not a represent a business opportunity, or opportunity of any other kind, for anyone, whether inside or outside of academia; and (vi)Why principles of Knowledge Management (KM) that are so useful when it comes to helping businesses that compete on the open market are completely useless, and indeed of negative utility, when it comes to helping universities solve their problems. -/- In the second part of this work, it is explained how to construct an online university that is both lucrative and also provides instruction that is faster, better, cheaper, and more useful than the instruction provided by any existing (or possible) brick-and-mortar university. Finally, it is explained how the principles of KM can be used to optimize such a university, once it is up and running. (shrink)

We introduce the notion T does not omit obstructions. If a stable theory does not admit obstructions then it does not have the finite cover property (nfcp). For any theory T, form a new theory by adding a new unary function symbol and axioms asserting it is an automorphism. The main result of the paper asserts the following: If T is a stable theory, T does not admit obstructions if and only if has a model companion. The proof involves some (...) interesting new consequences of the nfcp. (shrink)

The projective plane of Baldwin 695) is model complete in a language with additional constant symbols. The infinite rank bicolored field of Poizat 1339) is not model complete. The finite rank bicolored fields of Baldwin and Holland 371; Notre Dame J. Formal Logic , to appear) are model complete. More generally, the finite rank expansions of a strongly minimal set obtained by adding a ‘random’ unary predicate are almost strongly minimal and model complete provided the strongly minimal set is ‘well-behaved’ (...) and admits ‘exactly rank k formulas’. The last notion is a geometric condition on strongly minimal sets formalized in this paper. (shrink)

This book shows how Plato's "Statesman" and Thucydides' presentation of the moral collapse in Athenian political discourse reveal many points of agreement between Plato and Thucydides. Discussions of other dialogues including "Meno," "Laches," "Charmides," "Symposium," "Phaedo," "Sophist," and "Laws" confirm this agreement. Please see thucydides(dot)org for some editorial errata and corrections. The book was released in paperback in December 2021.

This book defends a comprehensive new vision of what addiction is and how people with addictions should be treated. The author argues that, in addition to physical and intellectual disabilities, there are volitional disabilities – disabilities of the will – and that addiction is best understood as a species of volitional disability. -/- This theory serves to illuminate long-standing philosophical and psychological perplexities about addiction and addictive motivation. It articulates a normative framework within which to understand prohibition, harm reduction, and (...) other strategies that aim to address addiction. The argument of this book is that these should ultimately be evaluated in terms of reasonable accommodations for addicted people and that the priority of addiction policy should be the provision of such accommodations. What makes this book distinctive is that it understands addiction as a fundamentally political problem, an understanding that is suggested by standard legal approaches to addiction, but which has not received a sustained defense in the previous philosophical or psychological literature. -/- This text marks a significant advance in the theory of addiction, one which should reshape our understanding of addiction policy and its proper aims.

New readings of Anselm’s speculative and spiritual writings brought in light of questions and thinkers from Augustine to today.

György Lukacs was a Hungarian Marxist philosopher, writer, and literary critic who shaped mainstream European Communist thought. _Soul and Form_ was his first book, published in 1910, and it established his reputation, treating questions of linguistic expressivity and literary style in the works of Plato, Kierkegaard, Novalis, Sterne, and others. By isolating the formal techniques these thinkers developed, Lukács laid the groundwork for his later work in Marxist aesthetics, a field that introduced the historical and political implications of text. For (...) this centennial edition, John T. Sanders and Katie Terezakis add a dialogue entitled "On Poverty of Spirit," which Lukács wrote at the time of _Soul and Form_, and an introduction by Judith Butler, which compares Lukács's key claims to his later work and subsequent movements in literary theory and criticism. In an afterword, Terezakis continues to trace the Lukácsian system within his writing and other fields. These essays explore problems of alienation and isolation and the curative quality of aesthetic form, which communicates both individuality and a shared human condition. They investigate the elements that give rise to form, the history that form implies, and the historicity that form embodies. Taken together, they showcase the breakdown, in modern times, of an objective aesthetics, and the rise of a new art born from lived experience. (shrink)

In the romantic tradition, music is consistently associated with madness, either as cause or cure. Writers as diverse as Kleist, Hoffmann, and Nietzsche articulated this theme, which in fact reaches back to classical antiquity and continues to resonate in the modern imagination. What John Hamilton investigates in this study is the way literary, philosophical, and psychological treatments of music and madness challenge the limits of representation and thereby create a crisis of language. Special focus is given to the decidedly (...) autobiographical impulse of the late eighteenth and early nineteenth centuries, where musical experience and mental disturbance disrupt the expression of referential thought, illuminating the irreducible aspects of the self before language can work them back into a discursive system. The study begins in the 1750s with Diderot's _Neveu de Rameau_, and situates that text in relation to Rousseau's reflections on the voice and the burgeoning discipline of musical aesthetics. Upon tracing the linkage of music and madness that courses through the work of Herder, Hegel, Wackenroder, and Kleist, Hamilton turns his attention to E. T. A. Hoffmann, whose writings of the first decades of the nineteenth century accumulate and qualify the preceding tradition. Throughout, Hamilton considers the particular representations that link music and madness, investigating the underlying motives, preconceptions, and ideological premises that facilitate the association of these two experiences. The gap between sensation and its verbal representation proved especially problematic for romantic writers concerned with the ineffability of selfhood. The author who chose to represent himself necessarily faced problems of language, which invariably compromised the uniqueness that the author wished to express. Music and madness, therefore, unworked the generalizing functions of language and marked a critical limit to linguistic capabilities. While the various conflicts among music, madness, and language questioned the viability of signification, they also raised the possibility of producing meaning beyond significance. (shrink)
