Following an account of the incommensurability argument, an objection, based on assumptions concerning rival theories, is examined and rejected. This rejection leads to an alternative direction of criticism of incommensurability, a direction that involves the articulation of comparative standards of theory evaluation that are independent of meaning invariance.

The contrast typically made between utilitarianism and virtue theory is overdrawn. Utilitarianism is a universal emulator: it implies that we should lie, cheat, steal, even appropriate Aristotle, when that is what brings about the best outcomes. In some cases and in some worlds it is best for us to focus as precisely as possible on individual acts. In other cases and worlds it is best for us to be concerned with character traits. Global environmental change leads to concerns about character (...) because the best results will be produced by generally uncoupling my behavior from that of others. Thus, in this case and in this world, utilitarians should be virtue theorists. (shrink)

Recent studies of naturalistic face‐to‐face communication have demonstrated coordination patterns such as the temporal matching of verbal and non‐verbal behavior, which provides evidence for the proposal that verbal and non‐verbal communicative control derives from one system. In this study, we argue that the observed relationship between verbal and non‐verbal behaviors depends on the level of analysis. In a reanalysis of a corpus of naturalistic multimodal communication (Louwerse, Dale, Bard, & Jeuniaux, ), we focus on measuring the temporal patterns of (...) specific communicative behaviors in terms of their burstiness. We examined burstiness estimates across different roles of the speaker and different communicative modalities. We observed more burstiness for verbal versus non‐verbal channels, and for more versus less informative language subchannels. Using this new method for analyzing temporal patterns in communicative behaviors, we show that there is a complex relationship between verbal and non‐verbal channels. We propose a “temporal heterogeneity” hypothesis to explain how the language system adapts to the demands of dialog. (shrink)

In recent years, many resourceful thinkers have brought a new clarity to the issues surrounding the doctrine of the Trinity. Two incompatible families of Trinitarian doctrine have been clearly distinguished: Social Trinitarianism and Latin Trinitarianism. I argue here that no theory in either camp has yet evaded the triune pitfalls of inconsistency, unintelligibility, and poor fit with the Bible. These two main approaches appear to be hopeless, and I argue that appeals to ‘mystery’ are no way to avoid the difficulties (...) at hand. Thus, the Trinitarian project is as yet unfinished.

In this paper, I present and explore an alternative to a standard prioritarian axiology. Equality-tempered prioritarianism holds that the value of welfare increases should be balanced against the value of equality. However, given that, under prioritarianism, the value of marginal welfare benefits decreases as the welfare of beneficiaries increases, equality-tempered prioritarianism holds that the intrinsic value of equality will be sufficient to alter a prioritarian verdict only in cases in which welfare benefits are granted to the very well-off. I argue (...) that this view, suitably refined, solves a persistent problem for prioritarianism, and is superior to alternatives. (shrink)

The philosophical study of what exists and what it means for something to exist is one of the core concerns of metaphysics. This introduction to ontology provides readers with a comprehensive account of the central ideas of the subject of being. This book is divided into two parts. The first part explores questions of pure philosophical ontology: what is meant by the concept of being, why there exists something rather than nothing, and why there is only one logically contingent actual (...) world. Dale Jacquette shows how logic provides the only possible answers to these fundamental problems. The second part of the book examines issues of applied scientific ontology. Jacquette offers a critical survey of some of the most influential traditional ontologies, such as the distinction between appearance and reality, and the categories of substance and transcendence. The ontology of physical entities - space, time, matter and causation - is examined as well as the ontology of abstract entities such as sets, numbers, properties, relations and propositions. The special problems posed by the subjectivity of mind and of postulating a god are also explored in detail. The final chapter examines the ontology of culture, language and art. (shrink)

After critiquing some earlier attempts (including those of Marcus Singer and Frances Howard–Snyder) to ground objections to actual–consequence act utilitarianism (ACAU) on human cognitive limitations, I present two new objections with this same foundation. Both start with the observation that, because human cognitive abilities are not up to the task of reliably recognizing utility–maximizing actions, any agents who are recognizably human – including the best possible humans, morally speaking – are certain to perform many actions every day that ACAU says (...) are immoral, and to perform some actions over the course of their lives that it says are highly immoral. The first objection is that, if Mill's analysis of what it means to call an action wrong is accurate, then ACAU entails a conclusion that no one will accept, viz., that the morally–best humans possible ought to undergo constant punishment. The second objection is that ACAU entails that even the morally–best humans possible are bad moral agents in some respect. This conclusion, while unpalatable, is not so obviously unacceptable as the first. However, I do briefly consider some ways in which it might be possible to demonstrate that it is false and thereby complete a reductio of ACAU. (shrink)

Francis Hutcheson’s theory of value is often characterized as a precursor to the qualitative hedonism of John Stuart Mill. The interpretation of Mill as a qualitative hedonist has come under fire recently; some have argued that he is, in fact, a hedonist of no variety at all.1 Others have argued that his hedonism is as non-qualitative as Bentham’s.2 The purpose of this essay is not to critically engage the various interpretations of Mill’s value theory. Rather, I hope to show that (...) Hutcheson should not be read as a qualitative hedonist. The evidence for Hutcheson as a qualitative hedonist is strong and striking. The most commonly cited passages are taken from his posthumous opus, A System of Moral .. (shrink)

This essay proposes and defends a general thesis concerning the nature of fallacies of reasoning. These in distinctive ways are all said to be deductively invalid. More importantly, the most accurate, complete and charitable reconstructions of these species and specimens of the informal fallacies are instructive with respect to the individual character of each distinct informal fallacy. Reconstructions of the fallacies as deductive invalidities are possible in every case, if deductivism is true, which means that in every case they should (...) be formalizable in an expressively comprehensive formal symbolic deductive logic. The general thesis is illustrated by a detailed examination of Walter Burleigh's paradox in his c. 1323 work, De Puritate Artis Logicae Tractatus Longior (Longer Treatise on the Purity of Logic), as a challenge to the deductive validity of hypothetical syllogism. The paradox has the form, ‹If I call you a swine, then I call you an animal; if I call you an animal, then I speak truly; therefore, if I call you a swine, then I speak truly'. Several solutions to the problem are considered, and the inference is exposed as an instance of the common deductive fallacy of equivocation. (shrink)

A clear and accessible introduction to the philosophy of mind, ideal for use on undergraduate courses.

Insofar as John Stuart Mill can be accurately described as a socialist, his is a socialism that a classical liberal ought to be able to live with, if not to love. Mill's view is that capitalist economies should at some point undergo a `spontaneous' and incremental process of socialization, involving the formation of worker-controlled `socialistic' enterprises through either the transformation of `capitalistic' enterprises or creation de novo. This process would entail few violations of core libertarian principles. It would proceed by (...) way of a series of voluntary transactions. Capitalists' property rights would be respected throughout. The process would take place within a national system of laws that permits private ownership of productive property and competition, and would not result in that system's overthrow. And, if we accept some basic tenets of Mill's social philosophy, the outcome at which we should expect the process to arrive is a `patchwork' economy in which capitalistic and socialistic enterprises exist side by side. Key Words: Ludwig von Mises • John Stuart Mill • socialism • capitalism • worker control. (shrink)

The liar paradox is standardly supposed to arise from three conditions: classical bivalent truth value semantics, the Tarskian truth schema, and the formal constructability of a sentence that says of itself that it is not true. Standard solutions to the paradox, beginning most notably with Tarski, try to forestall the paradox by rejecting or weakening one or more of these three conditions. It is argued that all efforts to avoid the liar paradox by watering down any of the three assumptions (...) suffers serious disadvantages that are at least as undesirable as the liar paradox itself. Instead, a new solution is proposed that admits that if the liar sentence is true then it is false, in the first paradox dilemma horn, but denies that the liar sentence is true, but asserting instead that it is false, and refuting the second paradox dilemma horn according to which it is supposed to follow that if the liar sentence is false then it is true. The reasoning for the second paradox dilemma horn is flawed, in that is not only not supported by but actually contradicted by the Tarskian truth schema. We could only infer the second dilemma horn if it were to clasically follow from the assumption that the liar sentence is false, and from the three liar paradox conditions, that therefore it is false that the liar sentence is false. This entire sentence can be shown to be false on the basis of the standard truth schema, thus blocking the paradox. Alternative formulations of the liar sentence are discussed, and the formal proofs and counterproofs for the two paradox dilemma horns, are considered along with the further philosophical implications of maintaining a resolute stance that the liar sentence is simply false.

Any enthymeme can be made logically valid by adding as a suppressed premise a conditional that reiterates the argument's stated content and inferential structure in if-then form, We cannot blanketly prohibit reiteration to avoid this sort of trivialization, because some enthymemes legitimately require completion by reiterative conditionals, The solution proposed here is to allow reiterative expansions, but to rank them, other things being equal, as less charitable than nonreiterative expansions. Reiterative expansions can then be chosen as the most charitable only (...) when all nonreiterative expansions have been eliminated for independent reasons. This pluralistic model encourages experimentation with a number of different permissible expansions in evaluating enthymemes, from the least controversial or problematic to the most trivializing and the least charitable.

In moral dilemmas, where circumstances prevent two or more equally justified prima facie ethical requirements from being fulfilled, it is often maintained that, since the agent cannot do both, conjoint obligation is overridden by Kant's principle that ought implies can, but that the agent nevertheless has a disjunctive obligation to perform one of the otherwise obligatory actions or the other. Against this commonly received view, it is demonstrated that although Kant's ought-can principle may avoid logical inconsistency, the principle is incompatible (...) with disjunctive obligation in standard deontic logic, and that it entails paradoxically that none of the conflicting dilemma actions will in fact occur. The principle appears to provide the only plausible safeguard against deontic antinomy, but cannot be admitted because of its collision with considered moral judgments. (shrink)

Jan Narveson has suggested that rational egoism might provide a defensible moral perspective that would put animals out of the reach of morality without denying that they are capable of suffering. I argue that rational egoism provides a principled indifference to the fate of animals at high cost: the possibility of principled indifference to the fate of “marginal humans.”.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XX, Number 2, November 1994, pp. 219-240 Infinite Divisibility in Hume's First Enquiry DALE JACQUETTE The Limitations of Reason The arguments against infinite divisibility in the notes to Sections 124 and 125 of David Hume's Enquiry Concerning Human Understanding are presented as "sceptical" results about the limitations of reason. The metaphysics of infinite divisibility is introduced merely as a particular, though especially representative problem, among (...) several that Hume discusses. Hume first writes: The chief objection against all abstract reasonings is derived from the ideas of space and time; ideas, which, in common life and to a careless view, are very clear and intelligible, but when they pass through the scrutiny of the profound sciences (and they are the chief object of these sciences) afford principles, which seem full of absurdity and contradiction.1 There follows an intuitive appeal to the apparent incoherence of the consequences of infinite divisibility in the geometry of space and measurement of time. Hume enlists natural belief against the infinite divisibility thesis in the mathematics of extension: But what renders the matter more extraordinary, is, that these seemingly absurd opinions are supported by a chain of reasoning, the Dale Jacquette is at the Department of Philosophy, The Pennsylvania State University, 246 Sparks Building, University Park PA 16802 USA. e-mail: [email protected] 220 Dale Jacquette clearest and most natural; nor is it possible for us to allow the premises without admitting the consequences. Nothing can be more convincing and satisfactory than all the conclusions concerning the properties of circles and triangles; and yet, when these are once received, how can we deny, that the angle of contact between a circle and its tangent is infinitely less than any rectilinear angle, that as you may increase the diameter of the circle in infinitum, this angle of contact becomes still less, even in infinitum, and that the angle of contact between other curves and their tangents may be infinitely less than those between any circle and its tangent, and so on, in infinitum? The demonstration of these principles seems as unexceptionable as that which proves the three angles of a triangle to be equal to two right ones, though the latter opinion be natural and easy, and the former big with contradiction and absurdity. (EHU 156-157) The implied sense of contradiction is then extended by Hume to the problem of infinite divisibility in time. The absurdity of these bold determinations of the abstract sciences seems to become, if possible, still more palpable with regard to time than extension. An infinite number of real parts of time, passing in succession, and exhausted one after another, appears so evident a contradiction, that no man, one should think, whose judgment is not corrupted, instead of being improved, by the sciences, would ever be able to admit of it. (EHU 157) The contradictions involved in traditional concepts of extension and time demarcate the limits of which reason is capable. But Hume's answer is more complex than merely surrendering to skepticism over the prospects of reason achieving understanding in the metaphysics of space and time. He tries to show that what he calls "Pyrrhonian" skepticism is ultimately self-defeating in its application of reason against reason. In place of a negative conclusion, he offers another solution to the paradoxes of infinite divisibility. What is remarkable about Hume's pronouncements against the infinite divisibility of extension and time, that may signal a change in his methodology if not his overall position on divisibility in the Enquiry from that of A Treatise of Human Nature, is his straightforward claim that natural belief rebels against the concept of infinite divisibility as its consequences apply to the metric of space and time.2 As in the Treatise, Hume pits natural disbelief in infinite divisibility against abstract metaphysical reason. But in the Enquiry, he does not invoke reason merely to correct the excesses of natural belief for the skeptical deflation of natural belief, say, in the necessity of causal connection, or the existence of mind-independent continuants. On the contrary, Hume Studies Infinite Divisibility in Hume's First Enquiry 221 Hume here appears instead to invoke natural disbelief in... (shrink)

In order that a degree-of-belief function be coherent it is necessary and sufficient that it satisfy the axioms of probability theory. This theorem relies heavily for its proof on the two-valued sentential calculus, which emerges as a limiting case of a continuous scale of truth-values. In this "continuum of certainty" a theorem analogous to that instanced above is proved.

A conceptual analysis of the problem of induction suggests that the difficulty of justifying probabilistic reasoning depends on a mistaken comparison between deductive and inductive inference. Inductive reasoning is accordingly thought to stand in need of special justification because it does not measure up to the standard of conditional absolute certainty guaranteed by deductive validity. When comparison is made, however, it appears that deductive reasoning is subject to a counterpart argument that is just as threatening to the justification of deductive (...) as to inductive inference. Trying to explain induction in such a way that it satisfies a special justificatory requirement in contrast with deduction is therefore not the way to justify induction. An alternative approach is sought in a style of justification developed by Aristotle for the law of noncontradiction and by Kant for the conclusions of transcendental reasoning that with variations can be used to justify both deduction and induction. This strategy upholds a principle when the principle must be presupposed even to raise doubts about the principle's justification. (shrink)

Analysis of quantifiers in Wittgenstein's Tractatus. A critical survey In the Tractatus Logico-Philosophicus, Wittgenstein distinguishes between what can and cannot be said in any language by the general form of propositions. I explain Wittgenstein's method and discuss Robert J. Fogelin's criticism of what he takes to be the incompleteness of Wittgenstein's general form of propositions in his exposition of the 'Naive Constructivism of the Tractatus.' I argue that Fogelin's objection is mistaken, and that, contrary to Fogelin's claim, Wittgenstein's method when (...) properly applied produces all of the well-formed formulas with mixed multiple quantification that Fogelin maintains it cannot provide. I conclude by offering a critical comparison of similar solutions proposed, among others, by P.T. Geach, Scott Soames, and Matthias Varga von Kibéd. (shrink)

In a chapter of - so to speak - an intellectual autobiography I sketch the reasons and ways I became a practitioning Meinongian logician. The way is a chain of transgressions, e.g., the transgression of extensionalism or of the law of excluded middle, and a struggle against widespread misinterpretations of Meinong's Gegenstandstheorie. Although the opposition towards Meinong's theory of objects persists in analytic philosophy, its main insights - that thought is intentional and that logic must be ontologically neutral - haven't (...) lost their attraction. Moreover: there is no substantive criticism to show that we cannot refer and truely predicate properties of intended objects regardless of their ontic status. (shrink)

The concept of a dialogue is considered in general terms from the standpoint of its referential presuppositions. The semantics of dialogue implies that dialogue participants must generally have a collective intentionality of agreed-upon references that is minimally sufficient for them to be able to disagree about other things, and ideally for outstanding disagreements to become clearer at successive stages of the dialogue. These points are detailed and illustrated in a fictional dialogue, in which precisely these kinds of referential confusions impede (...) progress in shared understanding. It is only through a continuous exchange of question and answer in this dialogue case study that the meanings of key terms and anaphorical references are disambiguated, and a relevantly complete collective intentionality of shared meaning between dialogue participants is achieved. The importance of a minimally shared referential semantics for the terms entering into reasoning and argument in dialogue contexts broadly construed cannot be over-estimated. Where to draw the line between referential agreement and disagreement within any chosen dialogue, as participants work toward better mutual understanding in clearing up referential incongruities, is sometimes among the dialogue’s main points of dispute.

Marx and Engels argue that capitalism must ultimately destroy itself because it contains an internal contradiction: Capitalism requires wage laborers at first to be in competitive isolation from one another, lest their common interests become transparent and they unite collectively to improve their employment conditions. At a certain later stage of capitalism's historical development, however, competition eventually forces capitalists to bring their workers together in common workplaces , where their shared interests can be immediately perceived and mutual grievances directly communicated. (...) The Communist Manifesto's argument for the inevitable downfall of capitalism is epistemically naïve in several ways, resting as it does on the idea that material interests are perceivable, and that an awareness of common problems translates automatically into a sense of shared interests powerful enough to motivate coordinated action for the sake of achieving economic-political reform.
