    Ethnobiology has become increasingly concerned with applied and normative questions about biocultural diversity and the livelihoods of local communities. While this development has created new opportunities for connecting ethnobiological research with ecological and social sciences, it also raises questions about the role of cognitive perspectives in current ethnobiology. In fact, there are clear signs of institutional separation as research on folkbiological cognition has increasingly found its home in the cognitive science community, weakening its ties to institutionalized ethnobiology. Rather than accepting this separation as inevitable disciplinary specialization, this short perspective article argues for a systemic perspective that addresses mutual influences and causal entanglement of cognitive and non-cognitive factors in socio-ecological dynamics. Such an integrative perspective requires a new conversation about cognition in ethnobiology beyond traditional polarization around issues of cognitive universals and cultural relativity.

    Interior–boundary conditions (IBCs) are boundary conditions on wave functions for Schrodinger equations that allow that probability can flow into (and thus be lost at) a boundary of configuration space while getting added in another part of configuration space. IBCs are of particular interest because they allow defining Hamiltonians involving particle creation and annihilation (as used in quantum field theories) without the need for renormalization or ultraviolet cut-off. For those Hamiltonians, the relevant boundary has codimension 3. In this paper, we develop (what we conjecture is) the general form of IBCs for the Laplacian operator (or Schrodinger operators), but we focus on the simpler case of boundaries with codimension 1.

    Evolutionary psychology is one of many biologically informed approaches to the study of human behavior. Along with cognitive psychologists, evolutionary psychologists propose that much, if not all, of our behavior can be explained by appeal to internal psychological mechanisms. What distinguishes evolutionary psychologists from many cognitive psychologists is the proposal that the relevant internal mechanisms are adaptations—products of natural selection—that helped our ancestors get around the world, survive and reproduce. To understand the central claims of evolutionary psychology we require an understanding of some key concepts in evolutionary biology, cognitive psychology, philosophy of science and philosophy of mind.

    In a recent paper, Werndl and Frigg discuss the relationship between the Boltzmannian and Gibbsian framework of statistical mechanics, addressing in particular the question when equilibrium values calculated in both frameworks coincide. In this comment, I point out serious flaws in their work and try to put their results into proper context. I also clarify the concept of Boltzmann equilibrium, the status of the “Khinchin condition” and their connection to the law of large numbers.

    To introduce what a philosopher could understand by identity and mutual recognition, we could first say that it make much of difference depending whether we focus on willing as much as the knowing self, in line with a Spinozist tradition keen in aligning rational grounds for ethics, or with Leibniz, Kant and Hegel to open the field of a subjective world of experience of the relation of ethical values, as given through our original trust in the world. In order to assess the importance of fine nuances in the overall sentiment of gratitude, we would like to present Spinoza’s careful use of the term in his Ethics, in an optic different from Descartes’ unconditional apology of the same. But, why to choose the early modern XVIIth Century Cartesian philosopher Baruch Spinoza to focus on moral sentiment ethics of mutual recognition?

    Walter Sinnott-Armstrong argues that ‘ought’ does not entail ‘can’, but instead conversationally implicates it. I argue that Sinnott-Armstrong is actually committed to a hybrid view about the relation between ‘ought’ and ‘can’. I then give a tensed formulation of the view that ‘ought’ entails ‘can’ that deals with Sinnott-Armstrong’s argument and that is more unified than Sinnott-Armstrong’s view.

    A.J. Ayer (1910–1989) was only 24 when he wrote the book that made his philosophical name, Language, Truth, and Logic (hereafter LTL), published in 1936. In it he put forward what were understood to be the major theses of logical positivism, and so established himself as the leading English representative of the movement, Viennese in origin. In endorsing these views Ayer saw himself as continuing in the line of British empiricism established by John Locke and David Hume, an empiricism whose most recent representative was Bertrand Russell. Throughout his subsequent career he remained true to this tradition’s rejection of the possibility of synthetic a priori knowledge, and so he saw the method of philosophy to be the analysis of the meaning of key terms, such as ‘causality’, ‘truth’, ‘knowledge’, ‘freedom’, and so on.

    Over the past decades, political philosophers and applied ethicists have been increasingly interested in the value of personal relationships. The goods they generate—or, perhaps, of which they consist—are obviously important, both instrumentally and non-instrumentally, for how well individuals’ lives go on various accounts of what makes a life good: They are highly desired by most people, can bring a lot of pleasure and joy and, at least some of them—such as friendship or love—have objective value. More recently, these goods have also been said to be relevant to determining individuals’ duties and even rights.

    Intuitionistic logic encompasses the general principles of logical reasoning which have been abstracted by logicians from intuitionistic mathematics, as developed by L. E. J. Brouwer beginning in his [1907] and [1908]. Because these principles also hold for Russian recursive mathematics and the constructive analysis of E. Bishop and his followers, intuitionistic logic may be considered the logical basis of constructive mathematics. Although intuitionistic analysis conflicts with classical analysis, intuitionistic Heyting arithmetic is a subsystem of classical Peano arithmetic. It follows that intuitionistic propositional logic is a proper subsystem of classical propositional logic, and pure intuitionistic predicate logic is a proper subsystem of pure classical predicate logic.

    The term ‘incommensurable’ means ‘to have no common measure’. The idea has its origins in Ancient Greek mathematics, where it meant no common measure between magnitudes. For example, there is no common measure between the lengths of the side and the diagonal of a square. Today, such incommensurable relations are represented by irrational numbers. The metaphorical application of this mathematical notion specifically to the relation between successive scientific theories became controversial in 1962 after it was popularised by two influential philosophers of science: Thomas Kuhn and Paul Feyerabend.

    The paper provides a critical discussion of the Super-Humean view of spacetime (Huggett’s regularity account) and the “minimalist ontology” in terms of Leibnizian relations and primitive matter points, recently developed by Esfeld et al. It investigates, in particular, the empirical adequacy of the proposed metaphysics, arguing that Super-Humeanism cannot provide a plausible account of space and time without committing to bona fide geometric structure in the fundamental relations. Against this backdrop, I propose a moderate version of Super-Humeanism and discuss its possible application to Euclidean space and General Relativity.

    Temporal reasoning with conditionals is more complex than both classical temporal reasoning and reasoning with timeless conditionals, and can lead to some rather counter-intuitive conclusions. For instance, Aristotle’s famous “Sea Battle Tomorrow” puzzle leads to a fatalistic conclusion: whether there will be a sea battle tomorrow or not, but that is necessarily the case now. We propose a branching-time logic LTC to formalise reasoning about temporal conditionals and provide that logic with adequate formal semantics. The logic LTC extends the Nexttime fragment of CTL , with operators for model updates, restricting the domain to only future moments where antecedent is still possible to satisfy. We provide formal semantics for these operators that implements the restrictor interpretation of antecedents of temporalized conditionals, by suitably restricting the domain of discourse. As a motivating example, we demonstrate that a naturally formalised in our logic version of the ‘Sea Battle’ argument renders it unsound, thereby providing a solution to the problem with fatalist conclusion that it entails, because its underlying reasoning per cases argument no longer applies when these cases are treated not as material implications but as temporal conditionals. On the technical side, we analyze the semantics of LTC and provide a series of reductions of LTC-formulae, first recursively eliminating the dynamic update operators and then the path quantifiers in such formulae. Using these reductions we obtain a sound and complete axiomatization for LTC, and reduce its decision problem to that of the modal logic KD.

    Alfred North Whitehead (1861–1947) was a British mathematician and philosopher best known for his work in mathematical logic and the philosophy of science. In collaboration with Bertrand Russell, he co-authored the landmark three-volume Principia Mathematica (1910, 1912, 1913). Later, he was instrumental in pioneering the approach to metaphysics now known as process philosophy. Although there are important continuities throughout his career, Whitehead’s intellectual life is often divided into three main periods. The first corresponds roughly to his time at Cambridge from 1884 to 1910. It was during these years that he worked primarily on issues in mathematics and logic.

    Conciliationists say that when you meet an epistemic peer who disagrees with you, you should alter your credence towards theirs. While there are counterexamples to conciliationism here is a simple argument that normally something like conciliationism is correct without the assumption of epistemic peerhood: That someone’s credence in a proposition p is significantly below 1/2 is normally evidence against p. Learning evidence against a proposition typically should lower one’s credence. …

    Ramsey famously pronounced that discounting “future enjoyments” would be ethically indefensible. Suppes enunciated an equity criterion implying that all individuals’ welfare should be treated equally. By contrast, Arrow (1999a, b) accepted, perhaps rather reluctantly, the logical force of Koopmans’ argument that no satisfactory preference ordering on a sufficiently unrestricted domain of infinite utility streams satisfies equal treatment. In this paper, we first derive an equitable utilitarian objective based on a version of the Vickrey–Harsanyi original position, extended to allow a variable and uncertain population with no finite bound. Following the work of Chichilnisky and others on sustainability, slightly weakening the conditions of Koopmans and co-authors allows intergenerational equity to be satisfied. In fact, assuming that the expected total number of individuals who ever live is finite, and that each individual’s utility is bounded both above and below, there is a coherent equitable objective based on expected total utility. Moreover, it implies the “extinction discounting rule” advocated by, inter alia, the Stern Review on climate change.

    While there are many ways to define social philosophy as a distinct field of study, I propose to look at it as constituted by a certain perspective on its objects. The ‘society’ in the focus of philosophical inquiry is less a specific object then a set of relations that can appear in different forms and on three different levels. Social philosophy, I argue, is well-advised to account for the different senses or appearances of the social in the form of order, of practices, and of social subjects. And it should account for three respective forms of power that operate at these three levels in rather specific ways. Reflection on these phenomena or figures of power can then lead to reflections on the possibility of transforming given social relations and therefore to the project of a possible politics. I offer a certain constellation or grid of concepts which can guide or frame social-philosophical investigations of such an orientation.

    Jack Spencer argues that we can perform actions that are metaphysically impossible to perform on the basis of cases like (Simple G): Simple G: Suppose that determinism is true. Let h be the complete specification of the initial conditions of the universe. Let l be the complete specification of the deterministic laws of the universe. Let hl be their conjunction. Suppose that G has not, does not, and will not believe that hl. G never finds herself reading a book or listening to a radio programme about the initial conditions or the laws of nature; G was home from school and sick with the flu on the day that her physics teacher covered the initial conditions and the laws of nature in class, and the physics teacher never bothered to go over the material again. We may suppose that it is fairly common knowledge in G’s community that hl, that matriculating high school seniors are expected to know that hl, that many of G’s classmates know that hl, and that G is one of the brightest students in her class.

    According to the kind of open futurist at issue, both of these claims may well fail to be true. According to many, however, the disjunction of these claims can be represented as p ∨ ~p – that is, as an instance of LEM. And if this is so, the open futurist is plainly in a difficult position. She must either deny LEM outright, or instead maintain that a disjunction can be true without either of its disjuncts being true. And whereas open futurists have defended both such options with considerable care and ingenuity, both are also faced with substantial costs.

    The problems of modern physics are man made. The Copenhagen version of quantum mechanics is formulated in a vague prosaic way, inconsistencies and paradoxes are the price. New interpretations try to solve the problem, however a reformulation rather than an interpretation is needed. In this manuscript I will point out, where the Copenhagen formulation of quantum mechanics is flawed and how one can make sense out of it. Then I will show, that it is possible to give a precise formulation of quantum mechanics without losing its compelling ability in describing experiments.

    According to a thesis often called ‘transparency,’ the deliberative question whether I should believe that p must give way to the factual question whether p, since “the only way to answer the question whether to believe that p is to answer the question whether p” (Shah and Velleman 2005: 499). Transparency is widely accepted by philosophers. Indeed, it’s standardly taken as a datum, and it’s so widely accepted that it is hard to find a philosopher who rejects it. But as I show in this note, transparency is false, since it cannot accommodate suspension of judgment. According to a thesis often called ‘transparency,’ the deliberative question whether I should believe that p must give way to the factual question whether p, since “the only way to answer the question whether to believe that p is to answer the question whether p,” as Shah and Velleman put it (2005: 499). Transparency does not say that answering the question whether p is one of multiple ways to answer the question whether I should believe that p. Nor does it say that, in order to answer the question whether I should believe that p, I must do multiple things, including answering the question whether p. It says that answering the question whether p suffices for answering the question whether I should believe that p, and it says that answering the question whether p is the only way to answer the question whether I should believe that p. If I want to know whether I should believe that p, there is only one thing I can do, and only one thing I must do: answer the question whether p. This is what transparency says.
