Hardy and Unruh constructed a family of non-maximally entangled states of pairs of particles giving rise to correlations that cannot be accounted for with a local hidden-variable theory. Rather than pointing to violations of some Bell inequality, however, they pointed to apparent clashes with the basic rules of logic. Specifically, they constructed these states and the associated measurement settings in such a way that the outcomes satisfy some conditionals but not an additional one entailed by them. Quantum mechanics avoids the (...) broken ‘if …then …’ arrows in such Hardy–Unruh chains, as we call them, because it cannot simultaneously assign truth values to all conditionals involved. Measurements to determine the truth value of some preclude measurements to determine the truth value of others. Hardy–Unruh chains thus nicely illustrate quantum contextuality: which variables do and do not obtain definite values depends on what measurements we decide to perform. Using a framework inspired by Bub and Pitowsky and developed in our book Understanding Quantum Raffles (co-authored with Michael E. Cuffaro), we construct and analyze Hardy–Unruh chains in terms of fictitious bananas mimicking the behavior of spin-1/2 particles. (shrink)

We use Bub's (2016) correlation arrays and Pitowksy's (1989b) correlation polytopes to analyze an experimental setup due to Mermin (1981) for measurements on the singlet state of a pair of spin-12 particles. The class of correlations allowed by quantum mechanics in this setup is represented by an elliptope inscribed in a non-signaling cube. The class of correlations allowed by local hidden-variable theories is represented by a tetrahedron inscribed in this elliptope. We extend this analysis to pairs of particles of arbitrary (...) spin. The class of correlations allowed by quantum mechanics is still represented by the elliptope; the subclass of those allowed by local hidden-variable theories by polyhedra with increasing numbers of vertices and facets that get closer and closer to the elliptope. We use these results to advocate for an interpretation of quantum mechanics like Bub's. Probabilities and expectation values are primary in this interpretation. They are determined by inner products of vectors in Hilbert space. Such vectors do not themselves represent what is real in the quantum world. They encode families of probability distributions over values of different sets of observables. As in classical theory, these values ultimately represent what is real in the quantum world. Hilbert space puts constraints on possible combinations of such values, just as Minkowski space-time puts constraints on possible spatio-temporal constellations of events. Illustrating how generic such constraints are, the equation for the elliptope derived in this paper is a general constraint on correlation coefficients that can be found in older literature on statistics and probability theory. Yule (1896) already stated the constraint. De Finetti (1937) already gave it a geometrical interpretation. (shrink)

This book offers a thorough technical elaboration and philosophical defense of an objectivist informational interpretation of quantum mechanics according to which its novel content is located in its kinematical framework, that is, in how the theory describes systems independently of the specifics of their dynamics. -/- It will be of interest to researchers and students in the philosophy of physics and in theoretical physics with an interest in the foundations of quantum mechanics. Additionally, parts of the book may be used (...) as the basis for courses introducing non-physics majors to quantum mechanics, or for self-study by those outside of the university with an interest in quantum mechanics.

In this book, Michael Madary examines visual experience, drawing on both phenomenological and empirical methods of investigation. He finds that these two approaches—careful, philosophical description of experience and the science of vision—independently converge on the same result: Visual perception is an ongoing process of anticipation and fulfillment. Madary first makes the case for the descriptive premise, arguing that the phenomenology of vision is best described as on ongoing process of anticipation and fulfillment. He discusses visual experience as being perspectival, temporal, (...) and indeterminate; considers the possibility of surprise when appearances do not change as we expect; and considers the content of visual anticipation. Madary then makes the case for the empirical premise, showing that there are strong empirical reasons to model vision using the general form of anticipation and fulfillment. He presents a range of evidence from perceptual psychology and neuroscience, and reinterprets evidence for the two-visual-systems hypothesis. Finally, he considers the relationship between visual perception and social cognition. An appendix discusses Husserlian phenomenology as it relates to the argument of the book. Madary argues that the fact that there is a convergence of historically distinct methodologies itself is an argument that supports his findings. With Visual Phenomenology, he creates an exchange between the humanities and the sciences that takes both methods of investigation seriously. (shrink)

Science and philosophy study well-being with different but complementary methods. Marry these methods and a new picture emerges: To have well-being is to be "stuck" in a positive cycle of emotions, attitudes, traits and success. This book unites the scientific and philosophical worldviews into a powerful new theory of well-being.

After outlining why the notion of conscious control of action matters to us and after distinguishing different challenges to that notion, the contribution focuses on the challenge posed by the literature on unconscious goal pursuit. Based on a conceptual clarification of the notion of consciousness, I argue that the understanding of consciousness in that literature is too restricted. The hypothesis that the behaviors reported can be accounted for by nonconceptual forms of consciousness, such as emotions and motor experiences, rather than (...) by—conscious or unconscious—conceptual level intentions tends to be disregarded, even though it promises to be empirically fruitful.

This book addresses such key ethical issues as euthanasia, the environment, biotechnology, abortion, the family, sexual ethics, and the distribution of health care resources. Michael Banner argues that the task of Christian ethics is to understand the world and humankind in the light of the credal affirmations of the Christian faith, and to explicate this understanding in its significance for human action through a critical engagement with the concerns, claims and problems of other ethics. He illustrates both the distinctiveness of (...) Christian convictions in relation to the above issues and also the critical dialogue with practices based on other convictions which this sense of distinctiveness motivates but does not prevent. The book's importance lies in its attempt to show the crucial difference which Christian belief makes to an understanding of these issues, whilst at the same time demonstrating some of the weaknesses and confusions of certain popular approaches to them.

In his engaging essay, “Deconstructing the Mind” (1996: 3-90), Stephen Stich raises some very good questions and gives some pretty good answers. My aim in this paper is to give some answers of my own, drawing on earlier work, and to compare these answers with Stich’s.

Reinforcement learning approaches to cognitive modeling represent task acquisition as learning to choose the sequence of steps that accomplishes the task while maximizing a reward. However, an apparently unrecognized problem for modelers is choosing when, what, and how much to reward; that is, when (the moment: end of trial, subtask, or some other interval of task performance), what (the objective function: e.g., performance time or performance accuracy), and how much (the magnitude: with binary, categorical, or continuous values). In this article, (...) we explore the problem space of these three parameters in the context of a task whose completion entails some combination of 36 state–action pairs, where all intermediate states (i.e., after the initial state and prior to the end state) represent progressive but partial completion of the task. Different choices produce profoundly different learning paths and outcomes, with the strongest effect for moment. Unfortunately, there is little discussion in the literature of the effect of such choices. This absence is disappointing, as the choice of when, what, and how much needs to be made by a modeler for every learning model. (shrink)

Many Sides is the first full-length study of Protagorean antilogic, an argumentative practice with deep roots in rhetorical history and renewed relevance for contemporary culture. Founded on the philosophical relativism of Protagoras, antilogic is a dynamic rather than a formal approach to argument, focused principally on the dialogical interaction of opposing positions (anti-logoi) in controversy. In ancient Athens, antilogic was the cardinal feature of Sophistic rhetoric. In Rome, Cicero redefined Sophistic argument in a concrete set of dialogical procedures. In turn, (...) Quintilian inherited this dialogical tradition and made it the centrepiece of his own rhetorical practice and pedagogy. Many Sides explores the history, theory, and pedagogy of this neglected rhetorical tradition and, by appeal to recent rhetorical and philosophical theory, reconceives the enduring features of antilogical practice in a dialogical approach to argumentation especially suited to the pluralism of our own age and the diversity of modern classrooms.

Kuyumcuoglu argues that defenders of sweatshop regulations should reject consequentialism and accept an ex ante interpretation of contractualism instead. In this Commentary I show that Kuyumcuoglu’s argument doesn’t succeed. Defenders of sweatshops shouldn’t become ex ante contractualists because its advantages on this issue are more apparent than real.

Creating focal lesions in primary visual cortex (V1) provides an opportunity to study the role of extra-geniculo-striate pathways for activating extrastriate visual cortex. Previous studies have shown that more than 95% of neurons in macaque area V2 and V3 stop firing after reversibly cooling V1 [1,2,3]. However, no studies on long term recovery in areas V2, V3 following permanent V1 lesions have been reported in the macaque. Here we use macaque fMRI to study area V2, V3 activity patterns from 1 (...) to 22 months after lesioning area V1. We find that visually driven BOLD responses persist inside the V1-lesion projection zones (LPZ) of areas V2 and V3, but are reduced in strength by ,70%, on average, compared to prelesion levels. Monitoring the LPZ activity over time starting one month following the V1 lesion did not reveal systematic changes in BOLD signal amplitude. Surprisingly, the retinotopic organization inside the LPZ of areas V2, V3 remained similar to that of the non-lesioned hemisphere, suggesting that LPZ activation in V2, V3 is not the result of input arising from nearby (non-lesioned) V1 cortex. Electrophysiology recordings of multi-unit activity corroborated the BOLD observations: visually driven multi-unit responses could be elicited inside the V2 LPZ, even when the visual stimulus was entirely contained within the scotoma induced by the V1 lesion. Restricting the stimulus to the intact visual hemi-field produced no significant BOLD modulation inside the V2, V3 LPZs. We conclude that the observed activity patterns are largely mediated by parallel, V1-bypassing, subcortical pathways that can activate areas V2 and V3 in the absence of V1 input. Such pathways may contribute to the behavioral phenomenon of blindsight. (shrink)

How to regard the weight we give to a proposition on the grounds of its being endorsed by an authority? I examine this question as it is raised within the epistemology of science, and I argue that “authority-based weight” should receive special handling, for the following reason. Our assessments of other scientists’ competence or authority are nearly always provisional, in the sense that to save time and money, they are not made nearly as carefully as they could be---indeed, they are (...) typically made on the basis of only a small portion of the available evidence. Consequently, we need to represent the authority-based elements of our epistemic attitudes in such a way as to allow the later revision of those elements, in case we decide in the light of new priorities that a more conscientious assessment is warranted. I look to the literature in confirmation theory, statistics, and economics for a semiformal model of this revision process, and make a particular proposal of my own. The discussion also casts some light on the question of why certain aspects of science’s epistemic state are not made public. (shrink)

IN SECTION X OF "AN INQUIRY CONCERNING HUMAN UNDERSTANDING", DAVID HUME RAISES TWO QUESTIONS ABOUT MIRACLES AND THEIR RELATION TO TESTIMONY. FIRST, HE ASKS WHETHER IT COULD EVER BE REASONABLE TO BELIEVE ON THE BASIS OF TESTIMONY THAT NATURE DOES NOT FIT THE IMAGE OF OUR SCIENCE, AND, SECOND, HE ASKS WHETHER IT COULD EVER BE REASONABLE TO BELIEVE ON THE BASIS OF TESTIMONY THAT NATURE IS NOT UNIFORM. HUME’S ANSWER TO THE FIRST QUESTION IS ’YES’ AND HIS ANSWER TO (...) THE SECOND IS ’NO’. HUME THINKS THAT A ’NO’ TO THE SECOND QUESTION SHOWS THAT BELIEF IN THE CHRISTIAN RELIGION IS LESS REASONABLE THAN A BELIEF IN MODERN SCIENCE. HOWEVER, HUME’S ’NO’ SEEMS TO OPPOSE HIS EMPIRICISM AND HIS BELIEF THAT THERE ARE NO NECESSARY TRUTHS ABOUT ANY MATTER OF FACT OR EXPERIENCE. THE POINT OF THIS PAPER IS TO SHOW THAT HUME CAN PROVE THAT THERE CAN BE NO TESTIMONY OF SUCH A QUANTITY OR QUALITY TO MAKE IT REASONABLE TO BELIEVE THAT NATURE IS NOT UNIFORM AND, AS RESULT, NO TESTIMONY TO MAKE IT REASONABLE TO.

Thomas Henry Huxley was one of the most prominent evolutionists of the late nineteenth century. A close companion of Charles Darwin, Huxley developed a reputation as "Darwin's Bulldog" for his relentless defense of evolutionary theory. Huxley was also an ardent supporter of social reform, particularly in his call for quality education at all levels. Evolution and Ethics, widely considered to be his greatest lecture, distilled a lifetime's wisdom and sensitive understanding of the nature and needs of humankind. Arguing that the (...) human psyche is at war with itself, that humans are alienated in the cosmos, and that moral societies are necessarily in conflict with the natural conditions of their existence, Huxley nevertheless saw moral dictates as the key to future human happiness and success. This new edition features an introduction by renowned historian and philosopher of biology Michael Ruse, placing Huxley's lecture in its original context while showing its even deeper relevance for our own time.

Think of a secret that you're keeping from others. It shouldn't take long; behavioral scientist Michael Slepian finds that on average, we are keeping as many as thirteen secrets at any given time. His research involving more than 50,000 participants from around the globe shows that the most common secrets include: lies we've told, addiction or mental health challenges, a hidden relationship, financial struggles, and more. Our secrets can weigh heavily upon us. Yet the burden of secrecy, Slepian argues, rarely (...) stems from the work it takes to keep a secret hidden. Rather, secrets are something we must "carry" because we do so alone, without the support of others. Whether we are motivated to protect our reputation, a relationship, or a loved one's feelings, or are pursuing some personal or professional goal, one thing is clear: holding back some part of our inner world is often lonely and isolating. But it doesn't have to be. Filled with fresh insight into one of the most universal-yet least understood-aspects of human behavior, The Secret Life of Secrets sheds a fascinating new light on questions like: At what age do children develop the cognitive capacity for secrecy? Do all secrets come with the same mental load? How can we reconcile our secrets with the human desire to relate, connect, and be known? When should we confess our secrets? Who makes for the ideal confidant? And can certain types of secrets actually enhance our well-being? (shrink)
