There has been much recent interest in imprecise probabilities, models of belief that allow unsharp or fuzzy credence. There have also been some influential criticisms of this position. Here we argue, chiefly against Elga (2010), that subjective probabilities need not be sharp. The key question is whether the imprecise probabilist can make reasonable sequences of decisions. We argue that she can. We outline Elga's argument and clarify the assumptions he makes and the principles of rationality he is implicitly committed to. (...) We argue that these assumptions are too strong and that rational imprecise choice is possible in the absence of these overly strong conditions. (shrink)

This paper explores some aspects of the relation between different ways of achieving a consensus on the judgemental values of a group of indviduals; in particular, aggregation and deliberation. We argue firstly that the framing of an aggregation problem itself generates information that individuals are rationally obliged to take into account. And secondly that outputs of the deliberative process that this initiates is in tension with constraints on consensual values typically imposed by aggregation theory, at least when deliberation is modelled (...) as process of learning from others compatible with Bayesian updating principles.

The chapter presents Bergson’s conception of philosophy as a way of life, as a thinking that seeks to make contact with the creativity of life as a whole. This endeavor to alter our vision of the world, and ultimately, our action and sense of being in the world, seeks to operate a “conversion of attention.” For Bergson, such a conversion is tied in with what he calls the “true empiricism” that allows us to experience and think change as that (...) which makes up living reality as a whole. Bergson conceptualizes this move beyond the human in terms of sympathy, a term employed both descriptively, to develop the notion of a sympathetic whole of life in which philosophy as a way of life resituates the self, and prescriptively, as urging us to overcome our estrangement from “the ocean of life” to which we owe our existence. This effort of sympathy takes the form of a spiritual exercise. Not limited to mere contemplation of the world, it transforms the manner in which we perceive the reality of duration and thus opens the path for a different way of living. (shrink)

During the Easter Season Year B of the Revised Common Lectionary invites participating churches to draw on early chapters of the Acts of the Apostles as the guiding reading for the principal Sunday service. This study employs the SIFT approach to biblical hermeneutics to engage a group of 24 Anglican clergy serving in Eastern Newfoundland to reflect on the Easter message within the mysterious case of the Ethiopian eunuch in Acts 8: 26-40. By inviting these clergy to work in type-alike (...) groups this study draws attention to the distinctive voices of sensing types, intuitive types, feeling types, and thinking types, as defined by psychological type theory. Sensing types gave close attention to the details within the text. Intuitive types identified the big themes arising from the text. Feeling types focused on the characters, the relationships and the values within the narrative. Thinking types analysed the issues and problems arising from the narrative. These data supported the hermeneutical theory proposed by the SIFT approach to biblical hermeneutics and illustrated the value of drawing on all four psychological functions in order to enrich the process and content of liturgical preaching.

This book offers a detailed account of Spinoza's influence on various schools of present-day critical thought. That influence extends from Althusserian Marxism to hermeneutics, deconstruction, narrative poetics, new historicism, and the unclassifiable writings of a thinker like Giles Deleuze. The author combines a close exegesis of Spinoza's texts with a series of chapters that trace the evolution of literary theory from its period of high scientific rigour in the mid-1960s to its latest "postmodern", neopragmatist or anti-theoretical phase. He examines the (...) thought of Althusser, Macherey and Deleuze as well as others who have registered the impact of his pioneering work without any overt acknowledgement. On the one hand, theorists like Althusser and Macherey could celebrate Spinoza as the first philosopher before Marx to understand the need for a riorous distinction between science and ideology. On the other, Deleuze makes Spinoza the hero of his crusade against theories of whatever kind - Kantian, Marxist, Freudian, post structuralist - which always end up by imposing some abstract order of concepts and categories on the libidinal flux of "desiring production", or the "body-without-organs" of anarchic instinctual drives.

Anticipatory looking on mindreading tasks can indicate our expectation of an agent's action. The challenge is that social situations are often more complex, involving instances where we need to track an agent's false belief to successfully identify the outcome to which an action is directed. If motor processes can guide how action goals are understood, it is conceivable— where that kind of goal ascription occurs in false-belief tasks— for motor representations to account for someone's belief-like state. Testing adults (N = (...) 42) in a real-time interactive helping scenario, we discovered that participants' early mediolateral motor activity (leftwards– rightwards leaning on balance board) foreshadowed the agent's belief-based action preparation. These results suggest fast belief-tracking can modulate motor representations generated in the course of one's interaction with an agent. While adults' leaning, and anticipatory looking, revealed the contribution of fast false-belief tracking, participants did not correct the agent's mistake in their final helping action. These discoveries suggest that adults may not necessarily use another's belief during overt social interaction or find reflecting on another's belief as being normatively relevant to one's own choice of action. Our interactive task design offers a promising way to investigate how motor and mindreading processes may be variously integrated. (shrink)

Pruss uses an example of Lester Dubins to argue against the claim that appealing to hyperreal-valued probabilities saves probabilistic regularity from the objection that in continuum outcome-spaces and with standard probability functions all save countably many possibilities must be assigned probability 0. Dubins’s example seems to show that merely finitely additive standard probability functions allow reasoning to a foregone conclusion, and Pruss argues that hyperreal-valued probability functions are vulnerable to the same charge. However, Pruss’s argument relies on the rule of (...) conditionalisation, but I show that in examples like Dubins’s involving nonconglomerable probabilities, conditionalisation is self-defeating.

This article argues that not only are there serious internal difficulties with both Garber’s and later ‘Garber-style’ solutions of the old-evidence problem, including a recent proposal of Hartmann and Fitelson, but Garber-style approaches in general cannot solve the problem. It also follows the earlier lead of Rosenkrantz in pointing out that, despite the appearance to the contrary which inspired Garber’s nonclassical development of the Bayesian theory, there is a straightforward, classically Bayesian, solution.

This article argues that common intuitions regarding (a) the specialness of ‘use-novel’ data for confirmation and (b) that this specialness implies the ‘no-double-counting rule’, which says that data used in ‘constructing’ (calibrating) a model cannot also play a role in confirming the model’s predictions, are too crude. The intuitions in question are pertinent in all the sciences, but we appeal to a climate science case study to illustrate what is at stake. Our strategy is to analyse the intuitive claims in (...) light of prominent accounts of confirmation of model predictions. We show that on the Bayesian account of confirmation, and also on the standard classical hypothesis-testing account, claims (a) and (b) are not generally true; but for some select cases, it is possible to distinguish data used for calibration from use-novel data, where only the latter confirm. The more specialized classical model-selection methods, on the other hand, uphold a nuanced version of claim (a), but this comes apart from (b), which must be rejected in favour of a more refined account of the relationship between calibration and confirmation. Thus, depending on the framework of confirmation, either the scope or the simplicity of the intuitive position must be revised. 1 Introduction2 A Climate Case Study3 The Bayesian Method vis-à-vis Intuitions4 Classical Tests vis-à-vis Intuitions5 Classical Model-Selection Methods vis-à-vis Intuitions 5.1 Introducing classical model-selection methods 5.2 Two cases6 Re-examining Our Case Study7 Conclusion.

It is sometimes suggested that victims of unjust harm should take priority over victims of other forms of harm. We explore four arguments for this view: that victims of unjust harm experience greater suffering; that prioritizing victims of unjust harm would help prevent unjust harm in the future; that it is good for perpetrators that their victims be prioritized; and that it is impersonally better that victims of unjust harm are prioritized. We argue that the first three arguments fail but (...) that the fourth argument succeeds. Moral agents have a reason to prioritize victims of wrongdoing because this secures the impersonal value of corrective justice. However, this reason can be activated differently for different agents depending on how they are situated relative to the wrongdoing, and it may be outweighed by other factors, such as the extent of the harm that could be alleviated.

In Knowing and Seeing, Michael Ayers presents a view of what he calls primary knowledge according to which one who knows in that way both knows perspicuously and knows how they know. Here, I use some general considerations about seeing, knowing, and knowing how one knows in order to raise some questions about this view. More specifically, I consider some putative limits on one’s capacity to know how one knows. The main question I pursue concerns whether perspicuity should be thought (...) of either (i) as a condition of sensory experience, (ii) as a condition of sense-based cognition, or (iii) as an interface condition, involving interrelations between sensory experience and sense-based cognition.

Our motor system can generate representations which carry information about the goals of another agent's actions. However, it is not known whether motor representations play a deeper role in social understanding, and, in particular, whether they enable tracking others' beliefs. Here we show that, for adult observers, reliably manifesting an ability to track another's false belief critically depends on representing the agent's potential actions motorically. One signature of motor representations is that they can be disrupted by constraints on an observed (...) agent's action capacities. We therefore used a `mummification' technique to manipulate whether the agent in a visual ball-detection task was free to act or whether he was visibly constrained from acting. Adults' reaction times reliably reflected the agent's beliefs only when the agent was free to act on the ball and not when the agent was visibly constrained from acting. Furthermore, it was the agent's constrained action capabilities, rather than any perceptual novelty, that determined whether adult observers' reaction times reliably reflected the agent's beliefs. These findings signal that our motor system may underpin more of social cognition than previously imagined, and, in particular, that motor representations may underpin automatic false-belief tracking.

William Lynch has provided an informed and probing critique of my embrace of the post-truth condition, which he understands correctly as an extension of the normative project of social epistemology. This article roughly tracks the order of Lynch’s paper, beginning with the vexed role of the ‘normative’ in Science and Technology Studies, which originally triggered my version of social epistemology 35 years ago and has been guided by the field’s ‘symmetry principle’. Here the pejorative use of ‘populism’ to mean democracy (...) is highlighted as a failure of symmetry. Finally, after rejecting Lynch’s appeal to a hybrid Marxian–Darwinism, Carl Schmitt and Thomas Hobbes are contrasted en route to what I have called ‘quantum epistemology’. (shrink)

Recent Work on Intrinsic Value brings together for the first time many of the most important and influential writings on the topic of intrinsic value to have appeared in the last half-century. During this period, inquiry into the nature of intrinsic value has intensified to such an extent that at the moment it is one of the hottest topics in the field of theoretical ethics. The contributions to this volume have been selected in such a way that all of the (...) fundamental questions concerning the nature of intrinsic value are treated in depth and from a variety of viewpoints. These questions include how to understand the concept of intrinsic value, what sorts of things can have intrinsic value, and how to compute intrinsic value. The editors have added an introduction that ties these questions together and places the contributions in context, and they have also provided an extensive bibliography. The result is a comprehensive, balanced, and detailed picture of current thinking about intrinsic value, one that provides an indispensable backdrop against which future writings on the topic may be assessed.

This note argues that quantum observables can include not just self-adjoint operators, but any member of the class of normal operators, including those with non-real eigenvalues. Concrete experiments, statistics, and symmetries are all expressed in this more general context. However, this more general class of observables also introduces a new restriction on which sets of operators can be interpreted as observables at once. These sets are referred to here as 'sharp sets.

According to Karl Popper, the evolution of science, logically, methodologically, and even psychologically, is an involved interplay of acute conjectures and blunt refutations. Like biological evolution, it is an endless round of blind variation and selective retention. But unlike biological evolution, it incorporates, at the stage of selection, the use of reason. Part I of this two-part paper begins by repudiating the common beliefs that Hume’s problem of induction, which compellingly confutes the thesis that science is rational in the way (...) that most people think that it is rational, can be solved by assuming that science is rational, or by assuming that Hume was irrational (that is, by ignoring his argument). The problem of induction can be solved only by a non-authoritarian theory of rationality. It is shown also that because hypotheses cannot be distilled directly from experience, all knowledge is eventually dependent on blind conjecture, and therefore itself conjectural. In particular, the use of rules of inference, or of good or bad rules for generating conjectures, is conjectural. Part II of the paper expounds a form of Popper’s critical rationalism that locates the rationality of science entirely in the deductive processes by which conjectures are criticized and improved. But extreme forms of deductivism are rejected. The paper concludes with a sharp dismissal of the view that work in artificial intelligence, including the JSM method cultivated extensively by Victor Finn, does anything to upset critical rationalism. Machine learning sheds little light on either the problem of induction or on the role that logic plays in the development of scientific knowledge. (shrink)

This paper argues that vice-charging, the practice of charging other persons with epistemic vice, can itself be epistemically vicious. It identifies some potential vices of vice-charging and identifies knowledge of other people as a type of knowledge that is obstructed by epistemically vicious attributions of epistemic vice. The hazards of vice-charging are illustrated by reference to the accusation that parents who hesitate to give their children the MMR triple vaccine are guilty of gullibility and dogmatism. Ethnographic and sociological research is (...) used to make the case that this charge is, in a significant range of cases, epistemically unjust and hinders attempts to make sense of vaccine hesitancy. This epistemic injustice consists in the representation of vaccine hesitant parents as less than full epistemic agents. A case is made for a more tolerant and inclusive approach, not only to vaccine hesitancy but also to other forms of unorthodoxy or non-compliance. The primary objective in these cases should be to achieve Verstehen of seemingly alien outlooks and practices so that policy makers and practitioners in public services can more effectively educate a sceptical public about the risks of vaccine hesitancy.

GRW Theory postulates a stochastic mechanism assuring that every so often the wave function of a quantum system is `hit', which leaves it in a localised state. How are we to interpret the probabilities built into this mechanism? GRW theory is a firmly realist proposal and it is therefore clear that these probabilities are objective probabilities (i.e. chances). A discussion of the major theories of chance leads us to the conclusion that GRW probabilities can be understood only as either single (...) case propensities or Humean objective chances. Although single case propensities have some intuitive appeal in the context of GRW theory, on balance it seems that Humean objective chances are preferable on conceptual grounds because single case propensities suffer from various well know problems such as unlimited frequency tolerance and lack of a rationalisation of the principal principle.

One of the major attempts to avoid this problem is to claim that the subject matter of laws are ascriptions of dispositions, powers, capacities etc., and not the regular behaviour we find in nature. 'Causal capacities can be measured as surely or unsurely as anything else that science deals with. Sometimes we measure capacities in a physics laboratory'. Many philosophers of science think that many laws of nature are so called ceteris paribus laws. Take the following statements for examples: 'All (...) laws are ceteris paribus laws. Although many think that there are ceteris paribus laws not only in the proviso ridden social sciences but even all the way down to fundamental physics the ceteris paribus clause in law statements is problematic. Real objects nearly never display the laws which are supposed to hold for them. If taken as statements about regularities laws are either all false or they are ceteris paribus laws because there are hardly ever regularities. (shrink)

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline (...) to provide a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

Through both an historical and philosophical analysis of the concept of possibility, we show how including both potentiality and actuality as part of the real is both compatible with experience and contributes to solving key problems of fundamental process and emergence. The book is organized into four main sections that incorporate our routes to potentiality: (1) potentiality in modern science [history and philosophy; quantum physics and complexity]; (2) Relational Realism [ontological interpretation of quantum physics; philosophy and logic]; (3) (...) Process Physics [ontological interpretation of relativity theory; physics and philosophy]; (4) on speculative philosophy and physics [limitations and approximations; process philosophy]. We conclude that certain fundamental problems in modern physics require complementary analyses of certain philosophical and metaphysical issues, and that such scholarship reveals intrinsic features and limits of determinism, potentiality and emergence that enable, among others, important progress on the quantum theory of measurement problem and new understandings of emergence.

The paper addresses the journal Jahrbücher für speculative Philosophie, published between 1846 and 1848 in Darmstadt. The paper focuses on the forewords of the journal written by the sole editor Ludwig Noack (1819–1885). In these forewords, Noack elaborates the current situation of philosophy. He outlines his vision for the future philosophy. It would be meaningful not only for professional philosophers but also for the general audience. Moreover, it would be closely associated with other sciences. Noack’s vision was (...) inspired by August Cieszkowski’s (1814–1894) so-called “Philosophie der Tat” (the philosophy of action), which resonated with the entire generation of German Hegelians from the late 1830s. Noack realized his journal in co-operation with the “Philosophische Gesellschaft zu Berlin”, founded by Cieszkowski and Georg Wilhelm Friedrich Hegel’s (1770–1831) former student Carl Ludwig Michelet (1801–1893) in 1843.

Even to begin discussing the ethics of animal experimentation we must locate our place in the “ethical three‐ring circus” of the debate among “human welfarists,” “animal rightists” and those in the “troubled middle.” A philosophy of “nature alive,” recognizing that some animals are more equal than others, can inform the troubled middle and ethically justify judicious animal research.

This paper introduces the philosophy of Grace Andrus de Laguna in order to renew interest in it. I show that, in the 1910s and 1920s, she develops ideas and arguments that are also found playing key roles in the development of analytic philosophy decades later. Further, I describe her sympathetic, but acute, criticism of pragmatism and Heideggerian ontology, and situate her work in the tradition of American, speculative philosophy. Before 1920, we will see, de Laguna appeals (...) to multiple realizability to undermine reductionism in science, to support perspectival, scientific realism and, with help from a private language argument, to favour the view that mental states are classified by behavioural, teleological roles over what came to be called ‘type physicalism’. Her view of speech, mostly developed in the 1920s, tells us that its primary role is coordinating group behaviour rather than expressing thoughts. Belief is understood in terms of its causal role, including its causal relations to other kinds of mental states, when coordinating group behaviour. Thought is similarly understood. In developing her theory of mind, de Laguna rejects the pragmatist claims that belief can be reduced to dispositions to behaviour and that thought’s function is to address specific, rather than general, problems. She also favours meaning holism and rejects the analytic–synthetic distinction. In later work, de Laguna argues that individuals’ activity of self-maintenance brings universals, conceived of as irreducible potentialities, into being and makes them increasingly determinate. Further, she identifies the existence of all individuals with forms of self-maintenance and takes the existence of people to include maintenance of the cultural world. Such a unified treatment of existence, she holds, permits making its evolution intelligible. Heidegger’s view of being is rejected for not permitting this. All de Laguna’s work, we will see, fits a vision of philosophy as the systematic, imaginative and naturalistic examination of being as well as a source of criticism of science. (shrink)

Speculative Philosophy, or Pure Metaphysic, stands at the present time in a very interesting position. There is perhaps some degree of slackening in the construction of elaborate systems, though, with the recent examples of McTaggart and Professor Alexander before us, this may be open to some question. But at least we probably realize, more fully than was possible in previous generations, the exact nature of the problems with which pure metaphysic is concerned. Its work has been more and (...) more clearly marked off from that of the empirical sciences, and from that of the mathematical sciences ; and its province can now be definitely confined to the general theory of knowledge and the light that is thrown by this upon the structure of reality. It is my object in this paper to indicate briefly the chief problems that appear to fall within its scope and the chief directions in which we may look for light upon them. It is well to admit, however, that metaphysical problems are difficult, and that any statements that are made about them, unless expressed in language of a somewhat technical character, are very liable to be misunderstood. I must try to avoid both the Scylla of obscurity and the Charybdis of superficiality. (shrink)

Regarding the state of contemporary metaphysics, as it has been said, “There’s something in the air.” My goal in this essay is to offer some brief reflections on the state of contemporary metaphysics, otherwise called contemporary “ speculative ” philosophy – the “something in the air” – that has resurfaced within the early part of the 21st century. In order to clarify the nature of the new metaphysics in question I proceed by isolating geographically and topically two main (...) tendencies of thought which appear to constitute it: namely continental realism and continental materialism. I argue that clarifying the nature of these tendencies better characterizes what metaphysics means today. With respect to the possible ambiguity of “continental realism” or “continental materialism ” in the 21st century, a consideration of “ speculative realism” seems necessary if only to position my analysis upon a specific conceptual map. From there I offer thoughts as to how contemporary continental realism and materialism may be said to be defined first and foremost by its engagement with a concept identified as “correlationism,” a central feature of the new metaphysics ’ rejection of the sort of philosophy that has come before it.

Although ostensibly defending speculative philosophy, Reck is doubtful that any unprejudiced speculative philosophy can exist: "No matter how much a philosopher may strive for neutrality, his test for the true philosophy is always predicated on the assumptions that his conception of being presents being as it is and that the conceptions of being his rivals uphold are partial or false." In the pursuit of neutrality, Reck attempts a mere chronicle of the distinctive conceptions of being (...) which he feels have animated the various metaphysical traditions: "Realism holds that whatever is in any sense is real; idealism that mind and its content alone are real; materialism that matter and its patterns alone are real; and process philosophy that process and the factors in process are real." The historical development of each of the four types is presented in masterly fashion. This book truly stands head and shoulders over its nearest rival in the Metaphilosophical literature for the depth of historical comprehension, the brilliant but controlled use made of a wealth of scholarship. A graduate student reviewing for comprehensive exams could do worse than to use Reck’s book. Those systems motivated at least in part by the drive-to-synthesis are disqualified a priori of being viable alternatives, motivated by distinctive intuitions. Realism, further, is found to have an inherent difficulty: "The task for the realist is to explain how the different levels or kinds of being can be related in a hierarchically ordered cosmos. The task is nothing short of explicating the bond of being." When Leibniz tries to relate finite particulars through a "Supreme Monad," he is faulted for "veering dangerously" close to Monism. Sympathetic toward Realism, Reck suggests a modification of Leibniz’s theory: not a rendering of the relations between man and God less mechanical, but a reduction of the "first Monad" from being supreme to a finite particular, struggling, like us, to overcome the hindrances posed by his environment. Reck concedes that the cognitive use of speculative philosophy, even when it redefines its project as Metaphilosophy, may be "futile"; however, he underscores the aesthetic value of the various systems, as Santayana would, when we can "bracket" the question of existence or truth and simply contemplate these cultural masterpieces as pure "essences." "Happy are those students who can suspend their critical search for truth sufficiently to savor the aesthetic values the systems of philosophy contain!" Reck refrains from judging between rival theories because such a judgment is always delivered from a view of what one takes to exist; and the impulse to go beyond "essence" to "existence" is, as Santayana teaches, prompted by fear, pain, instinct, or necessity. Rather than being a disinterested wonder at what "is," this passion is an "irrational agency of animal faith." "Needless to add," writes Reck, "animal faith is no more trustworthy than God’s existence to guarantee the truth of knowledge." This view can raise problems for Reck’s "finite" god. The finite god he prefers is perhaps "strong" enough to provide enough interconnection between existing particulars to justify a "Metaphilosophical" science, if not a properly "Philosophical" one, in the traditional sense; Reck could point to his own successful Metaphilosophy as evidence that his "god" is at least this strong. But isn't even this finite god an existential belief which, as the basis for a criticism, compromises one’s neutrality and thus constitutes a flaw in one’s Metaphilosophical theory? Is it possible that a totally adequate Metaphilosophical theory, on Reck’s canons, could not save enough interconnection between particulars to justify even a Metaphilosophy, as well as a Philosophy?—P.
