Remedios and Dusek have provided a useful contextualization of Steve Fuller’s recent work in social epistemology. While they have provided some good criticisms of some of Fuller’s new ideas, they fail to provide a systematic critique of Fuller’s retreat from a naturalistic and materialist social epistemology for one embracing transhumanism, intelligent design, and the proactionary imperative. An alternative approach is developed, drawing on Fuller’s early work and incorporating recent work on our biological and cultural evolution as a species.

How promising is Bitcoin as a currency? This paper discusses four claims on the advantages of Bitcoin: a more stable currency than state-backed ones; a secure and efficient payment system; a credible alternative to the central management of money; and a better protection of transaction privacy. We discuss these arguments by relating them to their philosophical roots in libertarian and neoliberal theories, and assess whether Bitcoin can effectively meet these expectations. We conclude that despite its advocates’ enthusiasm, there are good (...) reasons to doubt that Bitcoin can fulfill its promises and act as a functioning currency, rather than as a mere speculative asset.

There is a theorem that shows that it is impossible for an algorithm to jointly satisfy the statistical fairness criteria of Calibration and Equalised Odds non-trivially. But what about the recently advocated alternative to Calibration, Base Rate Tracking? Here, we show that Base Rate Tracking is strictly weaker than Calibration, and then take up the question of whether it is possible to jointly satisfy Base Rate Tracking and Equalised Odds in non-trivial scenarios. We show that it is not, thereby establishing (...) an even more general impossibility theorem. (shrink)

I provide a characterization of weakly pseudo-rationalizable choice functions---that is, choice functions rationalizable by a set of acyclic relations---in terms of hyper-relations satisfying certain properties. For those hyper-relations Nehring calls extended preference relations, the central characterizing condition is weaker than (hyper-relation) transitivity but stronger than (hyper-relation) acyclicity. Furthermore, the relevant type of hyper-relation can be represented as the intersection of a certain class of its extensions. These results generalize known, analogous results for path independent choice functions.

For much of its history, philosophy was not merely a theoretical discipline but a way of life, an "art of living." This practical aspect of philosophy has been much less dominant in modernity than it was in ancient Greece and Rome, when philosophers of all stripes kept returning to Socrates as a model for living. The idea of philosophy as an art of living has survived in the works of such major modern authors as Montaigne, Nietzsche, and Foucault. Each of (...) these writers has used philosophical discussion as a means of establishing what a person is and how a worthwhile life is to be lived. In this wide-ranging, brilliantly written account, Alexander Nehamas provides an incisive reevaluation of Socrates' place in the Western philosophical tradition and shows the importance of Socrates for Montaigne, Nietzsche, and Foucault. Why does each of these philosophers—each fundamentally concerned with his own originality—return to Socrates as a model? The answer lies in the irony that characterizes the Socrates we know from the Platonic dialogues. Socratic irony creates a mask that prevents a view of what lies behind. How Socrates led the life he did, what enabled or inspired him, is never made evident. No tenets are proposed. Socrates remains a silent and ambiguous character, forcing readers to come to their own conclusions about the art of life. This, Nehamas shows, is what allowed Montaigne, Nietzsche, and Foucault to return to Socrates as a model without thereby compelling them to imitate him. This highly readable, erudite study argues for the importance of the tradition within Western philosophy that is best described as "the art of living" and casts Montaigne, Nietzsche, and Foucault as the three major modern representatives of this tradition. Full of original ideas and challenging associations, this work will offer new ways of thinking about the philosophers Nehamas discusses and about the discipline of philosophy itself. (shrink)

Rush Rhees (1905-1989) was a philosopher, and a pupil and close friend of Ludwig Wittgenstein. While some of Rhees's own published papers became classics, most of his work remained unpublished during his lifetime. After his death, his papers were found to comprise sixteen thousand pages of manuscript on every aspect of philosophy, from philosophical logic to Simone Weil. This collection of unpublished papers, edited by D. Z. Phillips, includes Rhees's outstanding work on philosophy and religion. Written over an academic (...) lifetime, some of the papers are sympathetic to religion while others are not. It is Rhees's ability to interweave the personal and philosophical, and his integrity and intellectual honesty, which make this one of the most impressive books in twentieth-century philosophy of religion.

The question of how the probabilistic opinions of different individuals should be aggregated to form a group opinion is controversial. But one assumption seems to be pretty much common ground: for a group of Bayesians, the representation of group opinion should itself be a unique probability distribution, 410–414, [45]; Bordley Management Science, 28, 1137–1148, [5]; Genest et al. The Annals of Statistics, 487–501, [21]; Genest and Zidek Statistical Science, 114–135, [23]; Mongin Journal of Economic Theory, 66, 313–351, [46]; Clemen and (...) Winkler Risk Analysis, 19, 187–203, [7]; Dietrich and List [14]; Herzberg Theory and Decision, 1–19, [28]). We argue that this assumption is not always in order. We show how to extend the canonical mathematical framework for pooling to cover pooling with imprecise probabilities by employing set-valued pooling functions and generalizing common pooling axioms accordingly. As a proof of concept, we then show that one IP construction satisfies a number of central pooling axioms that are not jointly satisfied by any of the standard pooling recipes on pain of triviality. Following Levi, 3–11, [39]), we also argue that IP models admit of a much better philosophical motivation as a model of rational consensus. (shrink)

Recent impossibility theorems for fair risk assessment extend to the domain of epistemic justice. We translate the relevant model, demonstrating that the problems of fair risk assessment and just credibility assessment are structurally the same. We motivate the fairness criteria involved in the theorems as also being appropriate in the setting of testimonial justice. Any account of testimonial justice that implies the fairness/justice criteria must be abandoned, on pain of triviality.

In many assessment problems—aptitude testing, hiring decisions, appraisals of the risk of recidivism, evaluation of the credibility of testimonial sources, and so on—the fair treatment of different groups of individuals is an important goal. But individuals can be legitimately grouped in many different ways. Using a framework and fairness constraints explored in research on algorithmic fairness, I show that eliminating certain forms of bias across groups for one way of classifying individuals can make it impossible to eliminate such bias across (...) groups for another way of dividing people up. And this point generalizes if we require merely that assessments be approximately bias-free. Moreover, even if the fairness constraints are satisfied for some given partitions of the population, the constraints can fail for the coarsest common refinement, that is, the partition generated by taking intersections of the elements of these coarser partitions. This shows that these prominent fairness constraints admit the possibility of forms of intersectional bias. (shrink)

Four years after the publication of Wittgenstein's Investigations, Rush Rhees began writing critical reflections on the masterpiece he had helped to edit. In this edited collection of his previously unpublished writings, Rhees argues, contra Wittgenstein, that although language lacks the unity of a calculus it is not simply a family of language games. The unity of language is found in its dialogical character. It is in this context that we say something, and grow in understanding: notions not captured in (...) Wittgenstein's emphasis on language games, following rules, and using language. Rhees develops Wittgenstein's notion that to imagine a language is to image a form of life, without suggesting that we are all engaged in an all-inclusive conversation. The result is not only a major contribution to Wittgenstein scholarship, but an original discussion of central philosophical questions concerning the possibility of discourse. (shrink)

Our aim here is to present a result that connects some approaches to justifying countable additivity. This result allows us to better understand the force of a recent argument for countable additivity due to Easwaran. We have two main points. First, Easwaran’s argument in favour of countable additivity should have little persuasive force on those permissive probabilists who have already made their peace with violations of conglomerability. As our result shows, Easwaran’s main premiss – the comparative principle – is strictly (...) stronger than conglomerability. Second, with the connections between the comparative principle and other probabilistic concepts clearly in view, we point out that opponents of countable additivity can still make a case that countable additivity is an arbitrary stopping point between finite and full additivity.

In these discussions, Rush Rhees, who was a student and close friend of Wittgenstein, works out what he has learned from Wittgenstein's personal teaching and from study of his published and (at the time) unpublished writings. Some are review articles of books on Wittgenstein, and these are devoted to exposition of Wittgenstein's views. Others are independent discussions of special points in Wittgenstein's philosophy. The longest article, here published for the first time, is an account or record of what Wittgenstein (...) said about continuity in private discussion in 1938. (shrink)

Essays offer a glimpse of the Vienna-born philosopher's personality, character, and life's work.

Merging of opinions results underwrite Bayesian rejoinders to complaints about the subjective nature of personal probability. Such results establish that sufficiently similar priors achieve consensus in the long run when fed the same increasing stream of evidence. Initial subjectivity, the line goes, is of mere transient significance, giving way to intersubjective agreement eventually. Here, we establish a merging result for sets of probability measures that are updated by Jeffrey conditioning. This generalizes a number of different merging results in the literature. (...) We also show that such sets converge to a shared, maximally informed opinion. Convergence to a maximally informed opinion is a (weak) Jeffrey conditioning analogue of Bayesian “convergence to the truth” for conditional probabilities. Finally, we demonstrate the philosophical significance of our study by detailing applications to the topics of dynamic coherence, imprecise probabilities, and probabilistic opinion pooling. (shrink)

This paper generalizes rationalizability of a choice function by a single acyclic binary relation to rationalizability by a set of such relations. Rather than selecting those options in a menu that are maximal with respect to a single binary relation, a weakly pseudo-rationalizable choice function selects those options that are maximal with respect to at least one binary relation in a given set. I characterize the class of weakly pseudo-rationalizable choice functions in terms of simple functional properties. This result also (...) generalizes Aizerman and Malishevski's characterization of pseudo-rationalizable choice functions, that is, choice functions rationalizable by a set of total orders. (shrink)

Software plays an important role in contemporary research. Aside from its use for administering traditional instruments like surveys and in data analysis, the widespread use of mobile and web apps for social, medical and lifestyle engagement has led to software becoming a research intervention in its own right. For example, it is not unusual to find apps being studied for their utility as interventions in health and social life. Since the software may persist in use beyond the life of an (...) investigation, this raises questions as to the extent of ethical duties for researchers involved in its production and/or study towards the participants involved. Key factors identified include the extent of affect created by the software, the effect it has on a participant’s life, the length of investigation, cost of maintenance and participant agency. In this article we discuss the issues raised in such situations, considering them in the context of post-research duties of care and suggesting strategies to balance the burden on researchers with the need for ongoing participant support.

When in May 1930, the Council of Trinity College, Cambridge, had to decide whether to renew Wittgenstein's research grant, it turned to Bertrand Russell for an assessment of the work Wittgenstein had been doing over the past year. His verdict: The theories contained in this new work... are novel, very original and indubitably important. Whether they are true, I do not know. As a logician who like simplicity, I should like to think that they are not, but from what I (...) have read of them I am quite sure that he ought to have the opportunity to work them out, since, when completed, they may easily prove to constitute a whole new philosophy.

It is widely held that a successful theory of the mind will be neuroscientific. In this paper we ask, first, what this claim means, and, secondly, whether it is true. In answer to the first question, we argue that the claim is ambiguous between two views--one plausible but unsubstantive, and one substantive but highly controversial. In answer to the second question, we argue that neither the evidence from neuroscience itself nor from other scientific and philosophical considerations supports the controversial view.

Rush Rhees questions the viability of moral theories and the general claims they make in ethics. He shows how one can both be concerned with knowing what one ought to do while recognizing that one's answer is a personal one. These insights, arrived at in a distinctive style, characteristic of Rhees, are then applied to issues of life and death, human sexuality, and our relations to animals. To recognize why philosophy cannot answer such questions for us is an affirmation, (...) not a denial, of their importance. (shrink)

We explore which types of probabilistic updating commute with convex IP pooling. Positive results are stated for Bayesian conditionalization, imaging, and a certain parameterization of Jeffrey conditioning. This last observation is obtained with the help of a slight generalization of a characterization of externally Bayesian pooling operators due to Wagner :336–345, 2009). These results strengthen the case that pooling should go by imprecise probabilities since no precise pooling method is as versatile.

Kant infamously claimed that all human beings, without exception, are evil by nature. This collection of essays critically examines and elucidates what he must have meant by this indictment. It shows the role which evil plays in his overall philosophical project and analyses its relation to individual autonomy. Furthermore, it explores the relevance of Kant's views for understanding contemporary questions such as crimes against humanity and moral reconstruction. Leading scholars in the field engage a wide range of sources from which (...) a distinctly Kantian theory of evil emerges, both subtle and robust, and capable of shedding light on the complex dynamics of human immorality.

Between 1937 and 1951 Wittgenstein had numerous philosophical conversations with his student and close friend, Rush Rhees. This article is composed of Rhees’s notes of twenty such conversations — namely, all those which have not yet been published — as well as some supplements from Rhees’s correspondence and miscellaneous notes. The principal value of the notes collected here is that they fill some interesting and important gaps in Wittgenstein ’s corpus. Thus, firstly, the notes touch on a wide range (...) of subjects, a number of which are only briefly addressed by Wittgenstein elsewhere, if at all. The subjects discussed include: explanation, ethics, anarchism, contradiction, psychoanalysis, colour, religion, concepts, classification, seeing-as, evolution, the relation between science and philosophy, and free will, amongst others. Secondly, the notes contain references to, and brief remarks about, philosophers of whom Wittgenstein otherwise says very little, if anything — such as Brentano, Heidegger, Aquinas, and Marx, amongst others. And thirdly, the notes provide us with valuable examples of Wittgenstein ’s use of some key ‘Wittgensteinian’ terms of art which are surprisingly rare in his written works, such as ‘surface-’ and ‘depth-grammar’, and ‘centres of variation’.

Supra-Bayesianism is the Bayesian response to learning the opinions of others. Probability pooling constitutes an alternative response. One natural question is whether there are cases where probability pooling gives the supra-Bayesian result. This has been called the problem of Bayes-compatibility for pooling functions. It is known that in a common prior setting, under standard assumptions, linear pooling cannot be nontrivially Bayes-compatible. We show by contrast that geometric pooling can be nontrivially Bayes-compatible. Indeed, we show that, under certain assumptions, geometric and (...) Bayes-compatible pooling are equivalent. Granting supra-Bayesianism its usual normative status, one upshot of our study is thus that, in a certain class of epistemic contexts, geometric pooling enjoys a normative advantage over linear pooling as a social learning mechanism. We discuss the philosophical ramifications of this advantage, which we show to be robust to variations in our statement of the Bayes-compatibility problem. (shrink)

Our challenge begins with America's aversion to science. The problem is, of course, that nonscientists could understand scientific thinking, and would understand it, if they were encouraged and expected to do so. Though Members of Congress and their staff may avoid science, the institution itself cannot. Until the day comes when science is fully integrated into education for all, and even Members of Congress and congressional staff Members can deal with technical subjects, we will need special help for our legislation. (...) Likewise, ensuring that good science informs and infuses good public policy requires scientists engage in the process of self-governance. Science should not only be a tool of public policy, it should be its foundation. With a scientifically literate society and public policy grounded in sound science, America can maintain its leadership in the emerging global knowledge economy. Without these, America will lose the very things that have fueled its greatness. (shrink)

The question of context is fundamental in the debate on “What is art?” What the uses of the term mean colour all debates about life and art.

For two ideally rational agents, does learning a finite amount of shared evidence necessitate agreement? No. But does it at least guard against belief polarization, the case in which their opinions get further apart? No. OK, but are rational agents guaranteed to avoid polarization if they have access to an infinite, increasing stream of shared evidence? No.

An aspect of Peirce’s thought that may still be underappreciated is his resistance to what Levi calls _pedigree epistemology_, to the idea that a central focus in epistemology should be the justification of current beliefs. Somewhat more widely appreciated is his rejection of the subjective view of probability. We argue that Peirce’s criticisms of subjectivism, to the extent they grant such a conception of probability is viable at all, revert back to pedigree epistemology. A thoroughgoing rejection of pedigree in the (...) context of probabilistic epistemology, however, _does_ challenge prominent subjectivist responses to the problem of the priors. (shrink)

Theories of collective intentions must distinguish genuinely collective intentions from coincidentally harmonized ones. Two apparently equally apt ways of doing so are the ‘neo-reductionism’ of Bacharach (2006) and Gold and Sugden (2007a) and the ‘non-reductionism’ of Searle (1990, 1995). Here, we present findings from theoretical linguistics that show that we is not a cognitive primitive, but is composed of notions of I and grouphood. The ramifications of this finding on the structure both of grammatical and lexical systems suggests that (...) an understanding of collective intentionality does not require a primitive we-intention, but the notion of grouphood implicit in team reasoning, coupled with the individual concept I. This, we argue, supports neo-reductionism but poses difficulties for non-reductionism. (shrink)

The primary task confronting an examination of the claimed connection between Kant's general theory of cognition and his account of aesthetic judgment requires clarifying perhaps the most obscure component of that account, the doctrine of the harmony of the faculties. Kant's presentation of this doctrine makes it notoriously difficult to penetrate. Much of what Kant says about the harmony of the faculties – perhaps the very phrase “the harmony of the faculties” – is rather imprecise and metaphorical. Yet, the importance (...) of a correct understanding of the harmony of the faculties to assessing both the merits of Kant's aesthetic theory and his claims for the epistemological significance of reflection is difficult to overstate, for it is precisely this state of harmony that ultimately grounds the validity of judgments of taste and does so in virtue of being a state in which the most general prerequisites to conceptual judgment are present.

The rejection of behaviorism in the 1950s and 1960s led to the view, due mainly to Noam Chomsky, that language must be studied by looking at the mind and not just at behavior. It is an understatement to say that Chomskyan linguistics dominates the field. Despite being the overwhelming majority view, it has not gone unchallenged, and the challenges have focused on different aspects of the theory. What is almost universally accepted, however, is Chomsky’s view that understanding language demands a (...) theory that posits mental states that represent rules of language. Call this claim, following Cowie (1999), Representationalism or (R). According to (R), ‘‘[e]xplaining language mastery and acquisition requires the postulation of contentful mental states and processes involving their manipulation’’ (Cowie, 1999, p. 154). Although (R) is nothing more than the general assumption on which cognitive psychology is founded applied to the case of language, even it has had its detractors. Critics have argued that linguistic competence should not in fact be thought of as based on the possession of a body of linguistic knowledge but should be thought of, rather, as a kind of skill. This is an important challenge because one might be inclined to think that no recognizable form of Chomskyan linguistics could withstand the falsification of (R). In this paper we attempt to show that in fact (R) could be false without doing much damage to Chomskyan linguistics at all. Indeed, it is possible that the Chomskyan position could be made more coherent by adopting the view we will sketch. Our claim, therefore, is that critics of (R) might be right, but that this does not obviously make them serious critics of the Chomskyan program. (shrink)
