Some contextually sensitive expressions are such that their context independent conventional meanings need to be in some way supplemented in context for the expressions to secure semantic values in those contexts. As we’ll see, it is not clear that there is a paradigm here, but ‘he’ used demonstratively is a clear example of such an expression. Call expressions of this sort supplementives in order to highlight the fact that their context independent meanings need to be supplemented in context for them (...) to have semantic values relative to the context. Many philosophers and linguists think that there is a lot of contextual sensitivity in natural language that goes well beyond the pure indexicals and supplementives like ‘he’. Constructions/expressions that are good candidates for being contextually sensitive include: quantifiers, gradable adjectives including “predicates of personal taste”, modals, conditionals, possessives and relational expressions taking implicit arguments. It would appear that in none of these cases does the expression/construction in question have a context independent meaning that when placed in context suffices to secure a semantic value for the expression/construction in the context. In each case, some sort of supplementation is required to do this. Hence, all these expressions are supplementives in my sense. For a given supplementive, the question arises as to what the mechanism is for supplementing its conventional meanings in context so as to secure a semantic value for it in context. That is, what form does the supplementation take? The question also arises as to whether different supplementives require different kinds of supplementation. Let us call an account of what, in addition to its conventional meaning, secures a semantic value for a supplementive in context a metasemantics for that supplementive. So we can put our two questions thus: what is the proper metasemantics for a given supplementive; and do all supplementives have the same metasemantics? In the present work, I sketch the metasemantics I formulated for demonstratives in earlier work. Next, I briefly consider a number of other supplementives that I think the metasemantics I propose plausibly applies to and explain why I think that. Finally, I consider the prospects for extending the account to all supplementives. In so doing, I take up arguments due to Michael Glanzberg to the effect that supplementives are governed by two different metasemantics and attempt to respond to them. (shrink)

In this article I argue that the value of epistemic justification cannot be adequately explained as being instrumental to truth. I intend to show that false belief, which is no means to truth, can nevertheless still be of epistemic value. This in turn will make a good prima facie case that justification is valuable for its own sake. If this is right, we will have also found reason to think that truth value monism is false: assuming that true belief does (...) have value, there is more of final epistemic value than mere true belief.

Intentions are commonly conceived of as discrete mental states that are the direct cause of actions. In the last several decades, neuroscientists have taken up the project of finding the neural implementation of intentions, and a number of areas have been posited as implementing these states. We argue, however, that the processes underlying action initiation and control are considerably more dynamic and context sensitive than the concept of intention can allow for. Therefore, adopting the notion of ‘intention’ in neuroscientific explanations (...) can easily lead to misinterpretation of the data, and can negatively influence investigation into the neural correlates of intentional action.We suggest reinterpreting the mechanisms underlying intentional action, and we will discuss the elements that such a reinterpretation needs to account for.

The standard treatment of conditional probability leaves conditional probability undefined when the conditioning proposition has zero probability. Nonetheless, some find the option of extending the scope of conditional probability to include zero-probability conditions attractive or even compelling. This article reviews some of the pitfalls associated with this move, and concludes that, for the most part, probabilities conditional on zero-probability propositions are more trouble than they are worth.

I argue that the conjunction of perdurantism (the view that objects are temporally extended) and universalism (the thesis that any old class of things has a mereological fusion) gives rise to undesired complications when combined with certain plausible assumptions concerning the semantics of tensed statements.

Literature in epistemology tends to suppose that there are three main types of understanding – propositional, atomistic, and objectual. By showing that all apparent instances of propositional understanding can be more plausibly explained as featuring one of several other epistemic states, this paper argues that talk of propositional understanding is unhelpful and misleading. The upshot is that epistemologists can do without the notion of propositional understanding.

Much of the intuitive appeal of evidentialism results from conflating two importantly different conceptions of evidence. This is most clear in the case of perceptual justification, where experience is able to provide evidence in one sense of the term, although not in the sense that the evidentialist requires. I argue this, in part, by relying on a reading of the Sellarsian dilemma that differs from the version standardly encountered in contemporary epistemology, one that is aimed initially at the epistemology of (...) introspection but which generalizes to theories of perceptual justification as well. (shrink)

Outside of philosophy, ‘intuition’ means something like ‘knowing without knowing how you know’. Intuition in this broad sense is an important epistemological category. I distinguish intuition from perception and perception from perceptual experience, in order to discuss the distinctive psychological and epistemological status of evaluative property attributions. Although it is doubtful that we perceptually experience many evaluative properties and also somewhat unlikely that we perceive many evaluative properties, it is highly plausible that we intuit many instances of evaluative properties as (...) such. The resulting epistemological status of evaluative property attributions is very much like it would be if we literally perceived such properties. (shrink)

To what extent are cognitive capacities, especially perceptual capacities, informationally encapsulated and to what extent are they cognitively penetrable? And why does this matter? Two reasons we care about encapsulation/penetrability are: (a) encapsulation is sometimes held to be definitional of modularity, and (b) penetrability has epistemological implications independent of modularity. I argue that modularity does not require encapsulation; that modularity may have epistemological implications independently of encapsulation; and that the epistemological implications of the cognitive penetrability of perception are messier than (...) is sometimes thought. (shrink)

Human cognitive acts are directed towards objects extended in space of a wide range of different types. What follows is a new proposal for bringing order into this typological clutter. The theory of spatially extended objects should make room not only for the objects of physics but also for objects at higher levels, including the objects of geography and of related disciplines. It should leave room for different types of boundaries, including both the bona fide boundaries which we find in (...) the physical world and the fiat (or human-demarcation-induced) boundaries with which much of geography has to deal. Two distinct axiomatic theories of boundaries are accordingly presented, and the need for both is examined in some detail. The resultant dual framework is shown to have application above all for our understanding of issues involving contact, division, and separation, issues which have posed serious difficulties for the ontological theories of boundaries that have been proposed hitherto.

Epistemic internalism, by stressing the indispensability of the subject’s perspective, strikes many as plausible at first blush. However, many people have tended to reject the position because certain kinds of beliefs have been thought to pose special problems for epistemic internalism. For example, internalists tend to hold that so long as a justifier is available to the subject either immediately or upon introspection, it can serve to justify beliefs. Many have thought it obvious that no such view can be correct, (...) as it has been alleged that internalism cannot account for the possibility of the justification of beliefs stored in memory. -/- My aim in this paper is to offer a response that explains how memory justification is possible in a way that is consistent with epistemic internalism and an awareness condition on justification. Specifically, I will explore the plausibility of various options open to internalists, including both foundationalist and non-foundationalist approaches to the structure of justification. I intend to show that despite other difficult challenges that epistemic internalism might face, memory belief poses no special problems that the resources of internalism cannot adequately address.

Many advocate practices of ‘local food’ or ‘locavorism’ as a partial solution to the injustices and unsustainability of contemporary food systems. I think that there is much to be said in favor of local food movements, but these virtues are insufficient to immunize locavorism from criticism. In particular, three duties of international ethics—beneficence, repair and fairness—may provide reasons for constraining the developed world’s permissible pursuit of local food. A complete account of why (and how) the fulfillment of these duties constrains (...) locavorism will require extensive empirical evidence about the relationship between agricultural demand-led industrialization, international trade (rules), and local food practices. In this paper I can only gesture at some of this evidence and, for that reason, my policy prescriptions are merely provisional. Instead, the upshot of this paper is that advocates of locavorism ought to be attentive to the empirical-dependence of the moral permissibility of their projects. As local food ‘scales up’—and comes to be embraced as a goal of political communities—these concerns should receive even greater attention. (shrink)

Many assume that whenever government is entitled to make a law, it is entitled to enforce that law coercively. I argue that the justification of legal authority and the justification of governmental coercion come apart. Both in ideal theory and in actual human societies, governments are sometimes entitled to make laws that they are not entitled to enforce coercively.

Maurice Merleau-Ponty is often interpreted as claiming that opportunities for action are directly present in perceptual experience. However, he does not provide much evidence for how or why this would occur, and one can doubt that this is an appropriate interpretation of his phenomenological descriptions. In particular, it could be argued the Merleau-Pontyian descriptions mistakenly attribute pre-perceptual or post-perceptual elements such as allocation of attention or judgment to the perceptual experience itself. This paper argues for the Merleau-Pontyian idea that opportunities (...) for action are present in perceptual experience. It further argues that the phenomenological descriptions can be supported and explained via reference to contemporary research on motor imagery. In particular, it will be argued that non-conscious, covert motor imagery is used to prepare for and regulate skilled actions, and that it is plausible that this imagery combines with perception (likely vision) to create a single experience of the environment as enabling action. The paper will also show that contemporary views on motor imagery are broadly compatible with Merleau-Ponty’s aims. (shrink)

Recent work by Peijnenburg, Atkinson, and Herzberg suggests that infinitists who accept a probabilistic construal of justification can overcome significant challenges to their position by attending to mathematical treatments of infinite probabilistic regresses. In this essay, it is argued that care must be taken when assessing the significance of these formal results. Though valuable lessons can be drawn from these mathematical exercises (many of which are not disputed here), the essay argues that it is entirely unclear that the form of (...) infinitism that results meets a basic requirement: namely, providing an account of infinite chains of propositions qua reasons made available to agents.

Quine’s desert is generally contrasted with Meinong’s jungle, as a sober ontological alternative to the exuberant luxuriance that comes with the latter. Here I focus instead on the desert as a sober metaphysical alternative to the Aristotelian garden, with its tidily organized varieties of flora and fauna neatly governed by fundamental laws that reflect the essence of things and the way they can be, or the way they must be. In the desert there are no “natural joints”; all the boundaries (...) we find are lines we have drawn, artificial fencings that merely reflect of our own demarcations, our classifications, our desperate need to ward off the flux and meet an excusable but ungrounded demand for order and stability. The desert returns a picture of reality that is radically anti-realist. And yet the picture does not amount to a form of irrealism. The desert is out there and is what it is regardless of how we feel. And it is not completely structureless. It’s just that the structure it has is very thin and does not correspond to the sort of structure that so-called metaphysical realists—and scientific realists alike—tend to attribute to it. (shrink)

A graph-theoretic account of fibring of logics is developed, capitalizing on the interleaving characteristics of fibring at the linguistic, semantic and proof levels. Fibring of two signatures is seen as a multi-graph (m-graph) where the nodes and the m-edges include the sorts and the constructors of the signatures at hand. Fibring of two models is a multi-graph (m-graph) where the nodes and the m-edges are the values and the operations in the models, respectively. Fibring of two deductive systems is an (...) m-graph whose nodes are language expressions and the m-edges represent the inference rules of the two original systems. The sobriety of the approach is confirmed by proving that all the fibring notions are universal constructions. This graph-theoretic view is general enough to accommodate very different fibrings of propositional based logics encompassing logics with non-deterministic semantics, logics with an algebraic semantics, logics with partial semantics and substructural logics, among others. Soundness and weak completeness are proved to be preserved under very general conditions. Strong completeness is also shown to be preserved under tighter conditions. In this setting, the collapsing problem appearing in several combinations of logic systems can be avoided. (shrink)

In "Evil and the Justice of God", N.T. Wright presses the point that attempting to solve the philosophical problem of evil is an immature response to the existence of evil--a response that belittles the real problem of evil, which is just the fact that evil is bad and needs to be dealt with. As you might expect, I am not inclined to endorse this sort of sweeping indictment of the entire field of research on the philosophical problem of evil. (I (...) sort of doubt that Wright really meant to either.) But I do think that there is a kernel of truth in what I take to be Wright's fundamental objection to attempts to solve the philosophical problem of evil. In the first section of what follows, I will try briefly to explain why. I will then go on to argue that, despite this fact, certain efforts at solving the problem of evil avoid Wright's objection. Indeed, drawing on recent work by Elenore Stump, I will argue that one perfectly legitimate way to try to solve the philosophical problem of evil is to follow precisely what seems to be the main piece of advice in "Evil and the Justice of God": namely, to look more seriously than we have at the attitudes taken toward evil by human authors of and characters in the Bible, and to attend more carefully to what the Bible says about how God deals with evil.

From a European perspective the US debate about gun control is puzzling because we have no such debate: It seems obvious to us that dangerous weapons need tight control and that ‘guns’ fall under that category. I suggest that this difference occurs due to different habits that generate different attitudes and support this explanation with an analogy to the habits about knives. I conclude that it is plausible that individual knife-people or gun-people do not want tight regulatory legislation—but tight knife (...) and gun legislation is morally obligatory anyway. We need to give up our habits for the greater good. (shrink)

For any given society, its particular technology of communication has far-reaching consequences, not merely as regards social organization, but on the epistemic level as well. Plato's name-theory of meaning represents the transition from the age of primary orality to that of literacy; Wittgenstein's use-theory of meaning stands for the transition from the age of literacy to that of a second orality (audiovisual communication, electronic information processing). On the basis of a use-theory of meaning the problem of machine consciousness, to which (...) the later Wittgenstein again and again returned, is capable of a non-essentialist solution: appropriate changes in our form of life might well entail a radically different psychological language-game.

Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (shrink)

This article aims to serve as an accessible introduction to the idea of "ontotheology" and to the so-called "ontotheological critique of Western metaphysics" for which the twentieth-century German philosopher Martin Heidegger is especially well known. I begin by distinguishing two uses of "ontotheology" employed respectively by Kant and Heidegger, and go on to develop the Heideggerian interpretation and critique of ontotheology under three main headings: The Onto-theo-logical Constitution of Western Metaphysics; Ontotheology's Problematic Legacy: Anxiety, Calculation, Oblivion; and Ontotheology and God. (...) The article concludes with an annotated bibliography of helpful resources for learning more about ontotheology, the critique of ontotheology, and directions the critique has taken after Heidegger.

This paper defends a new argument for enabling citizen participation in government: individuals must have genuine opportunities to try to change the law in order to be able to satisfy duties of conscience. Without such opportunities, citizens who regard systems of related laws as partially unjust face a moral dilemma. If they comply with these laws willingly without also trying to change them, they commit a pro tanto wrong by willingly participating in injustice . If they disobey, or if they (...) obey only to avoid sanction, they respond inadequately to the morally important purposes that the laws advance despite their injustice. Government should help citizens avoid this dilemma. This argument bolsters the non-instrumentalist view that responsiveness in the political process is desirable even if it does not promote just legislative outcomes. It also helps to explain what governments owe to citizens with minority political views. (shrink)

A defense of the value of studying what Aristotle, in the Politics, refers to as useless things, and thereby a defense of the 'uselessness' of the study of the liberal arts.

Though most children can easily answer the question, "Who's your daddy?", the concept of paternity is complex and multifaceted. Courts have stumbled in answering it. In order to ground paternal rights and obligations in a satisfactory way, we need to disaggregate the various elements of stereotypical paternity. It is not sufficient merely to separate social from biological paternity. The latter concept, itself, is complex. We need to separate the procreative element of paternity from the genetic relationship.

We lay out the fatalist’s argument, making sure to clarify which dialectical moves are available to the libertarian. We then offer a more robust presentation of Ockhamism, responding to obvious objections and teasing out the implications of the view. At this point, we discuss presentism and eternalism in more detail. We then present our argument for the claim that the libertarian cannot take Ockham’s way out of the fatalism argument unless she rejects presentism. Finally, we consider and dispense with objections (...) to our argument. In the end, it ought to be clear that the libertarian must make a choice between Ockham’s way out and presentism. (shrink)

Leibniz said that the universe, if God-created, would exist at a unique, conjoint, physical maximum: Of all possible worlds, it would be richest in phenomena, but its richness would arise from the simplest physical laws and initial conditions. Using concepts of ‘‘variety’’ and algorithmic informational complexity, Leibniz’ claim can be reframed as a testable theory. This theory predicts that the laws and conditions of the actual universe should be simpler, and the universe richer in phenomena, than the presence of observers (...) would require. Tegmark has shown that inhabitants of an infinite multiverse would likely observe simple laws and conditions, but also phenomenal richness just great enough to explain their existence. Empirical observations fit the claim of divine choice better than the claim of an infinite multiverse. The future of the universe, including its future information-processing capacity, is predicted to be endless. -/- . (shrink)

In this paper, we defend Socratic studies as a research programme against several recent attacks, including at least one recently published in Polis . Critics have argued that the study of Socrates, based upon evidence mostly or entirely derived from some set of Plato's dialogues, is founded upon faulty and indefensible historical or hermeneutical technique. We begin by identifying what we believe are the foundational principles of Socratic studies, as the field has been pursued in recent years, and we then (...) show how the research programme that derives from accepting these principles is not defeated by any of the most common recent criticisms of it. Specifically, we argue that challenges to sorting Plato's dialogues by date, more general challenges to historicist interpretations of Plato's dialogues, as well as recent literary criticisms of Socratic studies all fail to undermine the research programme. We conclude with some thoughts about how and why Socratic studies has proved itself a valuable and fruitful research programme. (shrink)

We cannot disregard that the neuroscientific research on religious phenomena such as religious experiences and rituals for example, has increased significantly the last years. Neuroscientists claim that neuroscience contributes considerably in the process of understanding religious experiences, because neuroscience is able to measure brain activity during religious experiences by way of brain‐imaging technologies. No doubt, those results of neuroscientific research on religious experiences are an important supplement to the understanding of some types of religious experiences. However, some conclusions drawn from (...) neuroscientific research on religious experiences are arguable. For example, one such conclusion is that religious experiences are actually nothing but neural activity, i.e. there is nothing ‘religious’ to the experiences at all. Another such conclusion is that a person’s religious experiences actually derive from some ultimate reality, meaning that religious experiences are real. It is the latter assertion that will be analyzed in the present paper. The question is asked whether neuroscience alone is able to affirm that religious experiences are real or whether there are, besides neuroscientific issues, also cultural‐religious assumptions that underlie this conclusion.

When the reader turns to a text, he conceives of the narrated events as ordered in time. When the natural philosopher turns to the world, he also conceives of its events as ordered in time—or lately, in space-time. But each has the task of constituting this order on the basis of clues present in what is to be ordered. Interrogating the parallels to be found in their problems and methods, I shall argue that in both cases the definiteness of the (...) relation between the order and what is ordered resides mainly in how the matter is to be conceived, and is underdetermined by the facts.

I defend the thesis that psychological states can be literally ascribed only to living creatures and not to nonliving machines, such as sophisticated robots. Defenders of machine consciousness do not sufficiently appreciate the importance of the biological nature of a subject for the psychological significance of its behavior. Simulations of a computer-controlled, nonliving autonomous robot cannot carry the same psychological meaning as animate behavior. Being a living creature is an essential link between genuinely expressive behavior and justified psychological ascriptions.

Judith Butler’s influential work in feminist theory is significant for its insight that sexist discourse in popular culture affects the agency and consciousness of individuals, but offers an inadequate account of how such discourse might be said to touch, shape, or affect selves. Supplementing Butler’s account of signification with a Deweyan pragmatic account of meaning-making and selective emphasis enables a consistent account of the relationship between discourse and subjectivity with a robust conception of the bodily organism. An analysis of the (...) popular discourse surrounding Hillary Clinton in the 2008 Presidential campaign demonstrates why this hybrid pragmatic/poststructuralist account is necessary. (shrink)

Here is to take a closer look at some of these presuppositions and argue hat they may—when left unguarded—undermine much of Burns’ (...) general account. (shrink)

Certain consequentialists have responded to deontological worries regarding personal projects or options and agent-centered restrictions or constraints by pointing out that it is consistent with consequentialist principles that people develop within themselves, dispositions to act with such things in mind, even if doing so does not lead to the best consequences on every occasion. This paper argues that making this response requires shifting the focus of moral evaluation off of evaluation of individual actions and towards evaluation of whole character traits (...) and patterns of behavior. However, this weds consequentialism to a sort of psychological determinism, with which it is incompatible, because it makes any sort of assessment in terms of right or wrong incoherent. The paper concludes by sketching an ethical theory that abandons right and wrong as its organizing concepts, but nevertheless preserves much of the spirit of consequentialism. Relationships between whole patterns of behavior and the production of good and bad consequences can be studied and analyzed, and this information can be used to improve society and ourselves, without it being required that any individual persons acts or dispositions to behave be evaluated as right or wrong.

This paper argues that the Theaetetus establishes conditions on objects of knowledge which entail that only of Forms can there be knowledge. Plato's arguments for this are valid. The principles needed to make Plato's premises true will turn out to have deep connection with important parts of Plato's over-all theory, and to have consequences which Plato, in the middle dialogues, seems to welcome on other grounds as well.
