Bryan Caplan’s The Myth of the Rational Voter treats several immensely important and understudied topics—public ignorance of economics, political ideology, and their connection to policy error—from an orthodox economic perspective whose applicability to these topics is overwhelmingly disproven by the available evidence. Moreover, Caplan adds to the traditional and largely irrelevant orthodox economic notion of rational public ignorance the claim that when voters favor counterproductive economic policies, they do so deliberately, i.e., knowingly. This leads him to assume (without any evidence) (...) that “emotion or ideology” explain mass economic error. Straightforward, unchosen mass ignorance of economic principles—neither “rational” nor “irrational,” but simply mistaken—is a more coherent explanation for economic error, and it is backed up by the vast body of public‐opinion research.

We study the formalization within sybsystems of second-order arithmetic of theorems concerning periodic points in dynamical systems on the real line. We show that Sharkovsky's theorem is provable in WKL0. We show that, with an additional assumption, Sharkovsky's theorem is provable in RCA0. We show that the existence for all n of n-fold iterates of continuous mappings of the closed unit interval into itself is equivalent to the disjunction of Σ02 induction and weak König's lemma.

Throughout his metaphysical writings, Sellars maintains that current microtheory, with its particulate paradigm, can never depict adequately---even in principle---a universe populated with sentient beings like us. Why not? Experience for us involves the presence of an occurrent perceptual core of ultimately homogeneous secondary qualities. Sellars’ “Grain Argument” demonstrates that physical objects qua clouds of discrete particles cannot instantiate such qualities and that they cannot be assigned to an intrasentient realm construed as clusters of discrete, particulate neurons. Neither, contends Sellars, can (...) they simply be eliminated from the inventory of any theory claiming to be both empirical and conceptually independent of common sense. And since common sense fails to provide an adequate picture of reality, our only course is to abandon the particulate paradigm of current microtheory in favor of a process paradigm. This paper traces and develops, in dialog form, these arguments. (shrink)

The title of this Festschrift to Stephen Brown points to the understanding of medieval philosophy and theology in the longue durée of their traditions and discourses.

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

This paper analyzes the determinants of corporate reputation within a sample of large UK companies drawn from a diverse range of industries. We pay particular attention to the role that philanthropic expenditures and policies may play in shaping the perceptions of companies among their stakeholders. Our findings highlight that companies which make higher levels of philanthropic expenditures have better reputations and that this effect varies significantly across industries. Given that reputational indices tend to reflect the financial performance of organizations above (...) other factors (Fryxell, G. E. and J. Wang: 1994, Journal of Management 20, 1–14) and that elements of the literature emphasise that discretionary aspects of social responsibility, including corporate donations, may not be in the financial interests of organizations (e.g. Friedman, M.: 1970, “The Social Responsibility of Business is to Increase its Profits”, New York Times Magazine, September 13), this is a significant finding. It suggests that philanthropic expenditures may play a significant role in stakeholder management and may, in particular, lead to stakeholders holding more positive impressions of philanthropic corporations.

We show that there is a [Formula: see text]-model of second-order arithmetic in which the choice scheme holds, but the dependent choice scheme fails for a [Formula: see text]-assertion, confirming a conjecture of Stephen Simpson. We obtain as a corollary that the Reflection Principle, stating that every formula reflects to a transitive set, can fail in models of [Formula: see text]. This work is a rediscovery by the first two authors of a result obtained by the third author in (...) [V. G. Kanovei, On descriptive forms of the countable axiom of choice, Investigations on nonclassical logics and set theory, Work Collect., Moscow, 3-136 ]. (shrink)

Modal Platonism utilizes "weak" logical possibility, such that it is logically possible there are abstract entities, and logically possible there are none. Modal Platonism also utilizes a non-indexical actuality operator. Modal Platonism is the EASY WAY, neither reductionist nor eliminativist, but embracing the Platonistic language of abstract entities while eliminating ontological commitment to them.

Any consistent statement B ontologically committed to abstract entities may be replaced by an empirically equivalent modalization, MOD(B), not so ontologically committed. This (...) equivalence is provable using Modal/Actuality Logic S5@. Let MAX be a strong set theory with individuals. Then the following Schematic Bombshell Result (SBR) can be shown: MAX logically yields [T is true if and only if MOD(T) is true], for scientific theories T. The proof utilizes Stephen Neale's clever model-theoretic interpretation of Quantified Lewis S5, which I extend to S5@. (shrink)

A classical quantified modal logic is used to define a "feasible" arithmetic A 1 2 whose provably total functions are exactly the polynomial-time computable functions. Informally, one understands $\Box\alpha$ as "α is feasibly demonstrable". A 1 2 differs from a system A 2 that is as powerful as Peano Arithmetic only by the restriction of induction to ontic (i.e., $\Box$ -free) formulas. Thus, A 1 2 is defined without any reference to bounding terms, and admitting induction over formulas having arbitrarily (...) many alternations of unbounded quantifiers. The system also uses only a very small set of initial functions. To obtain the characterization, one extends the Curry-Howard isomorphism to include modal operations. This leads to a realizability translation based on recent results in higher-type ramified recursion. The fact that induction formulas are not restricted in their logical complexity, allows one to use the Friedman A translation directly. The development also leads us to propose a new Frege rule, the "Modal Extension" rule: if $\vdash \alpha$ then $\vdash A \leftrightarrow \alpha$ a for new symbol A. (shrink)

Part/whole is said in many ways: the leg is part of the table, the subset is part of the set, rectangularity is part of squareness, and so on. Do the various flavors of part/whole have anything in common? They may be partial orders, but so are lots of non-mereological relations. I propose an “upward difference transmission” principle: x is part of y if and only if x cannot change in specified respects while y stays the same in those respects.

My goal in this paper 1 is, first, to collect together a number of themes and observations that have usually been kept apart, locked up in their respective disciplines. When these are brought together, some general and far reaching implications become really rather clear. In particular, I want to make a case for the implicit coherence of these themes in the idea that.

According totransmissiontheories of testimony, a listener's belief in a speaker's testimony can be supported by the speaker's justification for what she says. The most powerful objection to transmission theories is Jennifer Lackey'spersistent believercase. I argue that important features about the epistemology of testimony reveal how transmission theories can account for Lackey's case. Specifically, I argue that transmission theorists should hold that transmission happens only if a listener believes a speaker's testimony based on the presumption that the speaker has justification for (...) what she says. If this does not happen in thepersistent believercase, then the case is no counterexample to transmission. If this does happen in thepersistent believercase, then there is an available framework for rejecting the idea that the listener's belief is in fact justified. (shrink)

According to some theories of testimonial knowledge, testimony can allow you, as a knowing speaker, to transmit your knowledge to me. A question in the epistemology of testimony concerns whether or not the acquisition of testimonial knowledge depends on the speaker's testimony being sincere. In this paper, I outline two notions of sincerity and argue that, construed in a certain way, transmission theorists should endorse the claim that the acquisition of testimonial knowledge requires sincerity.

In a dense and fascinating article of some ten years ago, Toomas Karmo adds his voice to the chorus of philosophers who deny the possibility of soundly deriving ‘ought’ from ‘is.’ According to Karmo, no derivation containing an ethical conclusion and only non-ethical premises can possibly be sound, where ‘sound’ describes a deductively valid derivation all of whose premises are true. He also suggests that the only valid derivations of ‘ought’ from ‘is’ will be trivial ones. His argument has, to (...) my knowledge, gone unrebutted; on the contrary, it has won recent endorsements, some philosophers evidently believing that he has finally put to rest the issue of the logical autonomy of ethics. Against that trend, I intend to rebut his argument, both by falsifying the taxonomy on which his argument relies and by offering a nontrivial and potentially sound ‘is’-‘ought’ derivation of my own.

This paper investigates the degree to which corporate philanthropy is influenced by the extent to which a firm is internationalised and/or whether it hasoperations in one or more controversial countries. Utilising data on a sample of large UK firms, we find evidence of a positive effect not for internationalisation per se, but only for a presence in these controversial countries. More specifically, we find evidence that in this connection the salient feature of a country is a lack of political rights (...) and/or civil liberties, rather than a presence of rampant corruption. Furthermore, this positive impact on charitable giving is restricted to a presence in only those countries that are, according to Freedom House indicators, most lacking (and so controversial) in this respect.

In this discussion, the author asks the question if Oakeshott’s famous depiction of a practice might be understood in relation to contemporary cognitive science, in particular connectionism (the contemporary cognitive science approach concerned with the problem of skills and skilled knowing) and in terms of the now conventional view of "normativity" in Anglo-American philosophy. The author suggests that Oakeshott meant to contrast practices to an alternative "Kantian" model of a shared tacit mental frame or set of rules. If cognitive science, (...) in its connectionist forms, allows us to give a naturalistic though nonreductive sense to his words, Oakeshott, like other philosophers who have employed the concept of tradition, expanded his discussion into a broader reconsideration of the nature of theorizing, a metaphilosophy. And this extension can be understood in relation to such recent thinkers as McDowell and, in particular, to the problem of the acquisition of the normative. Key Words: idealism • Oakeshott • connectionism • normativity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 37.1 (2004) 72-91 [Access article in PDF] Passing Theories through Topical Heuristics: Donald Davidson, Aristotle, and the Conditions of Discursive Competence Stephen R. Yarbrough Department of English The University of North Carolina at Greensboro What are the conditions of discursive competence? In "A Nice Derangement of Epitaphs" Donald Davidson explains how it is possible that in practice we can, with little effort, understand and appropriately (...) respond to linguistic anomalies such as the malapropism—anomalies because, by definition, the "language" cannot account for how we understand them. Such anomalies, Davidson concludes, are the exceptions that do not prove but refute the traditional rule that antecedent linguistic systems govern discursive meaning. If that is so, then meanings are not a property of a linguistic system and are not "governed by learned conventions or regularities" (1986, 436); therefore, learning and sharing such conventions, what we traditionally call "language," is not a necessary condition of successful communication. He shows this by arguing that two conditions must be met for successful interlocution and that meeting these sufficiently allows successful interlocution to take place. A third condition—that the interlocutors share a language, an organized set of learned conventions or regularities "learned in advance of occasions of interpretation" (436) for which phenomena such as malapropisms would be anomalous—is neither a necessary nor sufficient condition of discursive competence.What I hope to show in this paper is that the two conditions Davidson argues interlocution must meet in order to succeed both involve the interlocutor's implicit knowledge of what since Aristotle the rhetorical tradition has called topical heuristics. Although Davidson himself seems unaware of it, his philosophy places invention in a new light, one that allows us to understand that the invention process is not merely a supplement to discourse, useful only for professional speakers and writers, but intrinsic to all intercourse, and that the topics are not merely formal but pragmatic relations that develop from the processes of our interactions with others and with objects of our common concern in a world we can come to share. [End Page 72] Inferential method Davidson argues that the first condition necessary for successful interlocution is that "the interpreter can learn the semantic role of each of a finite number of words or phrases and can learn the semantic consequences of a finite number of modes of expression" (1986, 437). "For this to be possible," says Davidson, "there must be systematic relations between the meanings of utterances" (436). Here he is not talking about grammatical systems but about systematic relations between and among the interlocutors' discursive actions and the world with its objects to which their actions refer. As I'll explain more fully shortly, these are topical relations. What makes these relations possible, Davidson argues, is that the interlocutors share, not a set of learned conventions, but a "recursive characterization of the truth conditions of all possible utterances of the speaker" (437).Such a theory of truth can be something like a Tarski truth definition, the explanation of which can be extremely convoluted (see Davidson 1984), but it boils down to saying that an utterance is true if the anticipations raised by a belief in an interpreted utterance are met by the consequences of believing the utterance; or, to put it another way, if the utterance is an answer to the question that solicited it or a solution to the problem to which it responds. Thus, an example of such a truth definition would be "The grass is green (an utterance made by someone, somewhere, somewhen, under certain conditions) is true if and only if the grass is green (to that person, at that place, at that time, under those conditions)." The force of a Tarski truth definition is that to understand what an utterance means is to understand the conditions that make it true (to the speaker). This, in turn, implies that in order for the interpreter to learn the semantic roles of the speaker's words and phrases and the semantic consequences of her modes of expression, the... (shrink)

or reasons that seem to transcend cultural peculiarities, and may lie deep within the architecture of the human mind, we construct our descriptive taxonomies and tell our explanatory stories as dichotomies, or contrasts between inherently distinct and logically opposite alternatives.

This paper explores the notion of ‘expert’ health care practitioner in the context of critical thinking and health care education where scientific rather than philosophical inquiry has been the dominant mode of thought. A number of factors have forced are appraisal in this respect: the challenge brought about by the identification of complex ethical issues in clinical situations; medicine's `solving' of many of the simple health problems; the recognition that uncertainty is a common and perhaps innate feature of clinical practice; (...) debate about the concepts of illness and disease; plus insights from psychology,sociology and medical anthropology. Together these have prompted alternative ways of thinking which have the aim of identifying the best rather than the right decision (where best equates to good and right equates to correct in the sense of true or approved). It is argued that phronesis adds a necessary corrective dimension to modern Western medicine's over-emphasis on techne and is one of the factors that differentiates novice from expert practitioner. However, this attracts certain conflicts of interest: phronesis can only be gained and assessed from experience of praxis; agencies with legitimate interests in medicine such as government and professional registering bodies require more substantive criteria.

Recently in the pages of The Classical Quarterly Mathias Hanses convincingly demonstrated the existence of a fourth occurrence of the programmatic adjective λεπτός in Aratus, Phaen. 783–7. This new example occurs in the form of a diagonal acrostic alongside the known ‘gamma-acrostic’ and the occurrence of the same form of the adjective in line 784. Jerzy Danielewicz has now proposed yet a fifth instance of λεπτή in the form of an acronym spread over two lines and meant to be read (...) anticlockwise. (shrink)
