In Newcomb’s paradox you can choose to receive either the contents of a particular closed box, or the contents of both that closed box and another one. Before you choose though, an antagonist uses a prediction algorithm to accurately deduce your choice, and uses that deduction to fill the two boxes. The way they do this guarantees that you made the wrong choice. Newcomb’s paradox is that game theory’s expected utility and dominance principles appear to provide conflicting recommendations for what (...) you should choose. Here we show that the conflicting recommendations assume different probabilistic structures relating your choice and the algorithm’s prediction. This resolves the paradox: the reason there appears to be two conflicting recommendations is that the probabilistic structure relating the problem’s random variables is open to two, conflicting interpretations. We then show that the accuracy of the prediction algorithm in Newcomb’s paradox, the focus of much previous work, is irrelevant. We end by showing that Newcomb’s paradox is time-reversal invariant; both the paradox and its resolution are unchanged if the algorithm makes its ‘prediction’ after you make your choice rather than before.

W. V. Quine was the most important naturalistic philosopher of the twentieth century and a major impetus for the recent resurgence of the view that empirical science is our best avenue to knowledge. His views, however, have not been well understood. Critics charge that Quine’s naturalized epistemology is circular and that it cannot be normative. Yet, such criticisms stem from a cluster of fundamental traditional assumptions regarding language, theory, and the knowing subject – the very presuppositions that Quine is at (...) pains to reject. Through investigation of Quine’s views regarding language, knowledge, and reality, the author offers a new interpretation of Quine’s naturalism. The naturalism/antinaturalism debate can be advanced only by acknowledging and critiquing the substantial theoretical commitments implicit in the traditional view. Gregory argues that the responses to the circularity and non-normativity objections do just that. His analysis further reveals that Quine’s departure from the tradition penetrates the conception of the knowing subject, and he thus offers a new and engaging defence of Quine’s naturalism. (shrink)

Much liberal-democratic thought has concerned itself primarily – even exclusively – with coercive interference in citizens’ lives. But political actors do things – they engage in influential speech, they offer incentives, they mislead other actors, they disrupt the expected functioning of decision-making mechanisms etc. – that fall short of coercion, yet may nonetheless call for normative evaluation and public justification, precisely because they serve to purposively alter citizens’ beliefs, intentions and behaviour. With this article, I explicate a conception of political (...) manipulation to capture this sort of interference, and to distinguish individual manipulation from the manipulation of nonindividual agents like committees, institutions and states. The account, beyond being necessary for further work on the ethics of political manipulation, should prove useful to both normative thinkers interested in power, justice and the ethics of democratic decision-making, and empirical scholars in search of a conceptual apparatus to sharpen their investigations into the exercise of subtle forms of political power.

Carnap famously argued that metaphysics unavoidably involves a confusion between science and poetry. Unlike the lyric poet, who does not attempt to make an argument, the metaphysician attempts to make an argument while simultaneously lacking in musical talent. Carnap’s objection that metaphysics unavoidably involves a blend of philosophy and poetry is not a 20th century insight. Plato, in his beautifully crafted Phaedo, presents us with the imprisoned Socrates, who having been condemned to death for practicing philosophy in the Apology, has (...) a dream in which he realizes that he ought to make music. In this dialogue, however, Plato indicates no hint of the scorn that Carnap has for metaphysics—rather Socrates’ friends find him setting Aesop’s fables to verse. In the modern era, Nietzsche re-introduced the ‘music making Socrates’ in his Birth of Tragedy. But Nietzsche is not the first to revive the concept in modern philosophy. Before Nietzsche’s call for a new music-making Socrates, the early German Romantics, in particular Schlegel, explicitly called for the identification of poetry and science in the concept of Poesie. As Schlegel writes: ‘Alle Kunst soll Wissenschaft werden, und alle Wissenschaft Kunst werden; Poesie und Philosophie sollen vereinigt sein.’ On the one hand, in Ion Socrates is not wrong to critique Ion for not knowing the significance of his own work. On the other hand, Socrates himself recognizes in Phaedo that he is guilty of failing to heed the call to make music. Long misunderstood, the Romantic concept of Poesie is not mere irrationalism, for it offers an aesthetic metaphysics of the Absolute. Romanticism is indeed a philosophy of the Absolute, but one which cannot conceive of any solution to the profound impasses that confront philosophical knowing except by learning to make music.

So much has been written on this vexed issue, that one hesitates to reopen it. Yet one has no other choice when one finds scholars accepting as generally agreed a view which rests on altogether insufficient evidence. I propose, therefore, to examine the main grounds on which recent authorities interpret the disorderly motion of Tm 30a, 52d–53b, and 69b as a mythical symbol. They are four: I. That the Timaios is a myth; II. The testimony of the Academy; III. That (...) motion could not antecede the creation of time; IV. That motion could not antecede the creation of soul. (shrink)

"TAKE A LINE cut in two unequal sections, one for the kind that is seen, the other for the kind that is thought, and go on and cut each section in the same ratio". In order to follow this request, not only must one know geometry, which treats linear magnitudes; one must also know the relations between geometry and the art which treats kinds. The problem of the first cut in the line is the problem of determining what ratio of (...) two parts of a line is the same as the ratio of the two kinds: visible and thinkable. In order to solve this problem, a procedure seems to be needed for deciding when a ratio of magnitudes, a geometric ratio, is the same as a ratio of kinds, or at least what ratio of magnitudes is the same as the ratio of visible to thinkable.

Ecologists typically invoke "law-like" generalizations, ranging over "structural" and/or "functional" kinds, in order to explain generalizations about "historical" kinds (such as biological taxa)rather than vice versa. This practice is justified, since structural and functional kinds tend to correlate better with important ecological phenomena than do historical kinds. I support these contentions with three recent case studies. In one sense, therefore, ecology is, and should be, more nomothetic, or law-oriented, than idiographic, or historically oriented. This conclusion challenges several recent philosophical claims (...) about the nature of ecological science. (shrink)

Among the most interesting of the controversies in the recent history of parapsychology and related studies is the claim made in 1933 by the psychical researcher Harry Price that the medium Rudi Schneider had on one particular occasion produced his psychic effects by fraudulent means. The background to this event, and the controversy which followed it, are described in detail in this article, which draws on many hitherto unpublished materials. The issues involved range from the design of experiments in an (...) unusual area of science, through the relation between fringe and orthodox science, to the role of popularisers of science and the ethics of science.

Logic is a celebrated representation language because of its formal generality. But there are two senses in which a logic may be considered general, one that concerns a technical ability to discriminate between different types of individuals, and another that concerns constitutive norms for reasoning as such. This essay embraces the former, permutation-invariance conception of logic and rejects the latter, Fregean conception of logic. The question of how to apply logic under this pure invariantist view is addressed, and a methodology (...) is given. The pure invariantist view is contrasted with logical pluralism, and a methodology for applied logic is demonstrated in remarks on a variety of issues concerning non-monotonic logic and non-monotonic inference, including Charles Morgan’s impossibility results for non-monotonic logic, David Makinson’s normative constraints for non-monotonic inference, and Igor Douven and Timothy Williamson’s proposed formal constraints on rational acceptance.

There are situations in human life where the failure to perform a certain act can be morally blameworthy and at the same time not constitute the failure of moral duty or obligation. While traditional approaches to ethics have not acknowledged the possibility of these acts, recent contributions to the literature have made a strong and convincing case for their existence. Here I explain the nature of these acts, present some examples of these acts as they might arise in one''s business (...) or professional life, and point out the importance of recognizing and performing these acts for those who wish to practice good ethics in their business or professional lives.

Many philosophers of science have argued that a set of evidence that is "coherent" confirms a hypothesis which explains such coherence. In this paper, we examine the relationships between probabilistic models of all three of these concepts: coherence, confirmation, and explanation. For coherence, we consider Shogenji's measure of association (deviation from independence). For confirmation, we consider several measures in the literature, and for explanation, we turn to Causal Bayes Nets and resort to causal structure and its constraint on probability. All (...) else equal, we show that focused correlation, which is the ratio of the coherence of evidence and the coherence of the evidence conditional on a hypothesis, tracks confirmation. We then show that the causal structure of the evidence and hypothesis can put strong constraints on how coherence in the evidence does or does not translate into confirmation of the hypothesis.

Gregory Vlastos was one of the twentieth century's most influential scholars of ancient philosophy. Over a span of more than fifty years, he published essays and book reviews that established his place as a leading authority on early Greek philosophy. The two volumes that comprise Studies in Greek Philosophy include nearly forty contributions by this acknowledged master of the philosophical essay. Many of these pieces are now considered to be classics in the field. Perhaps more than any other modern (...) scholar, Gregory Vlastos was responsible for raising standards of research, analysis, and exposition in classical philosophy to new levels of excellence. His essays have served as paradigms of scholarship for several generations. Available for the first time in a comprehensive collection, these contributions reveal the author's ability to combine the skills of a philosopher, philologist, and historian of ideas in addressing some of the most difficult problems of ancient philosophy. Volume I collects Vlastos's essays on Presocratic philosophy. Wide-ranging concept studies link Greek science, religion, and politics with philosophy. Individual studies illuminate the thought of major philosophers such as Heraclitus, Parmenides, Anaxagoras, and Democritus. A magisterial series of studies on Zeno of Elea reveals the author's power in source criticism and logical analysis. Volume II contains essays on the thought of Socrates, Plato, and later thinkers and essays dealing with ethical, social, and political issues as well as metaphysics, science, and the foundations of mathematics.

Six experiments investigated variables predicted to influence subjects’ tendency to classify items by a single property instead of overall similarity, following the paradigm of Norenzayan et al., who found that European Americans tended to give more “logical” rule-based responses. However, in five experiments with Mechanical Turk subjects and undergraduates at an American university, we found a consistent preference for similarity-based responding. A sixth experiment with Korean undergraduates revealed an effect of instructions, also reported by Norenzayan et al., in which classification (...) instructions led to majority rule-based responding but similarity instructions led to overall similarity grouping. Our American subjects showed no such difference and used similarity more overall. We conclude that Americans do not have a preference for rule responding in classification and discuss the differences between tasks that reliably show strong rule or unidimensional preferences in contrast to this classification paradigm.

In A Theory of Justice, John Rawls argues that self-respect is ‘perhaps the most important’ primary good and that its status as such gives crucial support to controversial ideas like the lexical priority of liberty. Given the importance of these ideas for Rawls, it should be no surprise that they have attracted much critical attention. In response to these critics, I give a defense of self-respect that grounds its importance in Rawls’s moral conception of the person. I show that this (...) understanding of self-respect goes well beyond giving support to the lexical priority of liberty, also supporting Rawls’s still more controversial view of public reason. On my account, taking self-respect seriously requires the coercive enforcement of public reason. This is a novel argument for public reason, in that it grounds the idea in justice as fairness and mandates its coercive enforcement. (shrink)

My thesis is that Albert Camus offers key elements of a viable nonmetaphysical, post-secular ethical and political anthropology and explanation of evil. Idefend my thesis in two parts. First, I explicate and analyze Camus’s remarks on human nature and injustice primarily in his political essay The Rebel. Camus offers a nonmetaphysical picture of human nature, inspired by the Greeks, as that out of which rebellion to oppression springs but also as that which frustrates any final resolution to the problems of (...) history. Secondly, I offer a reading of The Fall. I argue that Camus’s depiction of human nature in this work, contrary to typical readings, highlights his appreciation of the insight and pragmatically desirable consequences of the Christian concept of sin. I show thatCamus depicts the possibility of a “healthy” guilt, a guilt linked to the pursuit of freedom and a responsibility to self and to others. (shrink)

Methodological likelihoodism is the view that it is possible to provide an adequate self-contained methodology for science on the basis of likelihood functions alone. I argue that methodological likelihoodism is false by arguing that an adequate self-contained methodology for science provides good norms of commitment vis-a-vis hypotheses, articulating minimal requirements for a norm of this kind, and proving that no purely likelihood-based norm satisfies those requirements.

It is suggested that, pace Michael Golby, recourse to metaphor has little role to play in enabling governing bodies to come to terms with their new and onerous responsibilities. The better way forward is a clearer appreciation of what is demanded of them by law.

A version of this op-ed appeared in print on May 10, 2015, on page SR9 of the New York edition of The New York Times with the headline : “Rhythms of the Brain”. It is also online here. IN 1890, the American psychologist William James famously likened our conscious experience to the flow of a stream. “A ‘river' or a ‘stream' are the metaphors by which it is most naturally described,” he wrote. “In talking of it hereafter, let's call it (...) the stream of thought, consciousness, or subjective life.” - Biologie – Nouvel article.

The Neoplatonist philosophers who flourished between the third and sixth centuries AD had a profound influence on western philosophy, on both Christian and Islamic literature and the visual arts from the Renaissance to modern times. This extensively revised and updated second edition of Neoplatonists provides a valuable introduction to the thought of four central Neoplatonic philosophers, Plotinus, Porphyry, Proclus and Iamblichus. John Gregory presents new translations of a selection of key passages from Neoplatonist writings, an introduction that puts in (...) context the writings, and an epilogue detailing the legacy and influence of Neoplatonist thought.

Nevin & Grace invoke a behavioral metaphor from the physics of momentum. The idealized assumptions they invoke are argued to translate to behavior only in the limited case of steady-state, constant-probability VI responding. Rather than further refine this limit case, mathematical models should be applied to generalizations of the limit case itself, broadening our understanding of behavioral processes.

In this project, I explore and defend William Alston's claim that God does not have beliefs. Rather, He knows what He knows by direct intuition of facts. This direct intuition is absolute immediate awareness. It is immediate in that God knows what He knows without the mediation of other objects of knowledge. It is absolute in that His knowledge is not mediated by any other factors such as causal links between the object of knowledge and God's consciousness of it. ;My (...) central argument is that if God knows all facts by direct intuitive awareness, He must be atemporal. If God is temporal, He could not have direct intuitive awareness of past or future facts. This is because absolute immediate awareness cannot span time. A knowing subject who is temporal can have direct intuitive awareness only of those facts which are temporally present. ;My argument that direct intuitive awareness cannot span time focusses on God's experience of a temporal now. A temporal God will experience what is happening now in a manner which is different than His experience of the past or the future. I argue that God's cognitive experience of past or future facts must be mediated in some way. If this is the case, it is not absolute immediate awareness. Therefore, a temporal God can have direct intuitive awareness only of present facts. In order to have direct intuitive awareness of all facts, regardless of their temporal locations, God must be atemporal. (shrink)

Evan Fales has argued that divine causation is not possible. His central argument involves an analysis of causation that requires that there has to be a mapping feature to guarantee that the particular effect follows the particular cause. He suggests that being related in space and time will provide the means to map the right effects onto their causes. In this paper, I argue that the spatial relation between cause and effect is not necessary to the causal relation. In cases (...) of volition, it appears that the mapping of particular effects onto volitions is achieved by the intentional content of the volition. Therefore, spatial relations are not necessary to causation and the impossibility of divine causation has not been shown. (shrink)
