Descartes' Meditations is one of the most thoroughly analyzed of all philosophical texts. Nevertheless, central issues in Descartes' thought remain unresolved, particularly the problem of the Cartesian Circle. Most attempts to deal with that problem have weakened the force of Descartes' own doubts or weakened the goals he was seeking. In this book, Stephen I. Wagner gives Descartes' doubts their strongest force and shows how he overcomes those doubts, establishing with metaphysical certainty the existence of a non-deceiving God and (...) the truth of his clear and distinct perceptions. Wagner's innovative and thorough reading of the text clarifies a wide range of other issues that have been left unclear by previous commentaries, including the nature of the cogito discovery and the relationship between Descartes' proofs of God's existence. His book will be of great interest to scholars and upper-level students of Descartes, early modern philosophy and theology. (shrink)

This paper spells out the implications, for Descartes's theory of ideas, of my earlier paper, "Descartes's Wax: Discovering the Nature of Mind." I show that my reading of the wax investigation provides a number of clarifications of Descartes's Meditation III discussion of ideas. My reading of Meditation III provides a ground, internal to the Meditations for Descartes's claims about objective reality, the causal laws, material falsity and the idea of God. I show that Descartes's claims and conclusions regarding these issues (...) is strengthened by the perspective I have provided. (shrink)

THIS PAPER PROVIDES A READING OF DESCARTES' COGITO WHICH RESOLVES THE PROBLEMS ENCOUNTERED BY THE OTHER PREVALENT ANALYSES OF HIS THOUGHT. I FIRST INDICATE THE WAYS IN WHICH THE INFERENTIAL AND PERFORMATIVE VIEWS FAIL TO ADEQUATELY EXPLICATE DESCARTES' OWN STATEMENTS REGARDING THE COGITO. I THEN SET OUT MY "GENERATIVE VIEW" AND SHOW THAT IT PROVIDES A FULLY CONSISTENT READING OF THESE SAME STATEMENTS. I CONCLUDE THAT THE GENERATIVE VIEW MORE ADEQUATELY REPRESENTS DESCARTES' INTENTIONS.

Descartes' procedure in "Meditation II" must be brought into line with his claim that "we must never ask about the existence of anything until we first understand its essence." And Descartes' "Meditation III" claim that he is aware of his mind's power to cause ideas must be grounded in a prior discovery of this power. Both demands are met by reading "Meditation II" as a progressive clarification of the nature of mind, with the investigation of the wax providing the discovery (...) of the mind's generative power. This process of discovery also provides the meanings of "thinking" and "existing" -- as "causing ideas" and "exercising causal power", respectively. Thus the discovery of the mind's nature also grounds the cogito. I provide a close reading of the wax investigation which supports this view. (shrink)

This chapter discusses a re-emerging topic in Cartesian scholarship—mind and body interaction. A number of thinkers, from his contemporaries onward, have maintained that Descartes' account of his two substances rules out the possibility of the interaction that he attempted to defend. Often, however, the ground for asserting this impossibility has been left less than explicit. Recent discussion has attempted to clarify the issue by asking whether there can be specified grounds within Descartes' philosophy which are sufficient to rule out mind–body (...) interaction. There are three elements of Descartes' thinking which might seem to create problems for mind–body interaction—his insistence that mind and body are absolutely distinct substances, his own restrictions on possible causal relations, and his views on the freedom of the will. Recent work has focused on the first two of these issues. The chapter's goal is to suggest that an essential element of Descartes' worldview has been overlooked in this recent discussion, and to show that once it is taken into account many of the apparent difficulties about Cartesian interaction can be resolved.

We present a model for several early stages of the sensorimotor transformations involved in targeted arm movement. In psychophysical experiments, human subjects pointed to the remembered locations of randomly placed targets in three-dimensional space. They made consistent errors in distance, and from these errors stages in the sensorimotor transformation were deduced. When subjects attempted to move the right index finger to a virtual target they consistently undershot the distance of the more distal targets. Other experiments indicated that the error was (...) in the sensorimotor transformation rather than in the perception of distance. The error was most consistent when evaluated using a spherical coordinate system based at the right shoulder, indicating that the neural representation of target parameters is transformed from a retinocentric representation to a shoulder-centered representation. According to the model, the error in distance results from the neural implementation of a linear approximation in the algorithm to transform shoulder-centered target parameters into a set of arm orientations appropriate for placing the finger on the target. The transformation to final arm orientations places visually derived information into a frame of reference where it can readily be combined with kinesthetically derived information about initial arm orientations. The combination of these representations of initial and final arm orientations could give rise to the representation of movement direction recorded in the motor cortex by Georgopoulos and his colleagues. Later stages, such as the transformation from kinematic to dynamic parameters, or to levels of muscle activation, are beyond the scope of the present model. (shrink)

Many upper limb amputees experience an incessant, post-amputation “phantom limb pain” and report that their missing limbs feel paralyzed in an uncomfortable posture. One hypothesis is that efferent commands no longer generate expected afferent signals, such as proprioceptive feedback from changes in limb configuration, and that the mismatch of motor commands and visual feedback is interpreted as pain. Non-invasive therapeutic techniques for treating phantom limb pain, such as mirror visual feedback (MVF), rely on visualizations of postural changes. Advances in neural (...) interfaces for artificial sensory feedback now make it possible to combine MVF with a high-tech “rubber hand” illusion, in which subjects develop a sense of embodiment with a fake hand when subjected to congruent visual and somatosensory feedback. We discuss clinical benefits that could arise from the confluence of known concepts such as MVF and the rubber hand illusion, and new technologies such as neural interfaces for sensory feedback and highly sensorized robot hand testbeds, such as the “BairClaw” presented here. Our multi-articulating, anthropomorphic robot testbed can be used to study proprioceptive and tactile sensory stimuli during physical finger-object interactions. Conceived for artificial grasp, manipulation, and haptic exploration, the BairClaw could also be used for future studies on the neurorehabilitation of somatosensory disorders due to upper limb impairment or loss. A remote actuation system enables the modular control of tendon-driven hands. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. The provision of multimodal sensory feedback that is spatiotemporally consistent with commanded actions could lead to benefits such as reduced phantom limb pain, and increased prosthesis use due to improved functionality and reduced cognitive burden.

Noam Chomsky's rationalist account of the human mind has won many adherents and attracted many critics. What has been little noticed on either side of the debate is that Chomsky's rationalism is best viewed as a pair of quite distinct doctrines about the mental mechanisms responsible for language acquisition. One of these doctrines, the one I will call rigid rationalism, entails the other, which I call anti-empiricism, but the entailment is not mutual. Rigid rationalism is much the stronger of the (...) two. What is more, the argument Chomsky offers for rigid rationalism is quite distinct from the argument for anti-empiricism. In the first section of this paper I will set out what I take to be the most favourable interpretation of each of these doctrines, along with the argument supporting it. (shrink)

Sufferers of eating disorders often hold false beliefs about their own body size. Such beliefs appear to violate norms of rationality, being neither grounded by nor responsive to appropriate forms of evidence. I defend the rationality of these beliefs. I argue that they are in fact supported by appropriate evidence, emanating from proprioceptive misperception of bodily boundaries. This argument has far‐reaching implications for the explanation and treatment of eating disorders, as well as debates over the relationship between rationality and human (...) psychology. (shrink)

Sosa’s topic is the use of intuitions in philosophy. Much of what I have written on the issue has been critical of appeals to intuition in epistemology, though in recent years I have become increasingly skeptical of the use of intuitions in ethics and in semantic theory as well.

Inferentialism claims that expressions are meaningful by virtue of rules governing their use. In particular, logical expressions are autonomous if given meaning by their introduction-rules, rules specifying the grounds for assertion of propositions containing them. If the elimination-rules do no more, and no less, than is justified by the introduction-rules, the rules satisfy what Prawitz, following Lorenzen, called an inversion principle. This connection between rules leads to a general form of elimination-rule, and when the rules have this form, they may (...) be said to exhibit “general-elimination” harmony. Ge-harmony ensures that the meaning of a logical expression is clearly visible in its I-rule, and that the I- and E-rules are coherent, in encapsulating the same meaning. However, it does not ensure that the resulting logical system is normalizable, nor that it satisfies the conservative extension property, nor that it is consistent. Thus harmony should not be identified with any of these notions. (shrink)

Bell’s theorem has fascinated physicists and philosophers since his 1964 paper, which was written in response to the 1935 paper of Einstein, Podolsky, and Rosen. Bell’s theorem and its many extensions have led to the claim that quantum mechanics and by inference nature herself are nonlocal in the sense that a measurement on a system by an observer at one location has an immediate effect on a distant entangled system. Einstein was repulsed by such “spooky action at a distance” and (...) was led to question whether quantum mechanics could provide a complete description of physical reality. In this paper I argue that quantum mechanics does not require spooky action at a distance of any kind and yet it is entirely reasonable to question the assumption that quantum mechanics can provide a complete description of physical reality. The magic of entangled quantum states has little to do with entanglement and everything to do with superposition, a property of all quantum systems and a foundational tenet of quantum mechanics.

Some intuitive normative principles raise vexing 'detaching problems' by their failure to license modus ponens. I examine three such principles (a self-reliance principle and two different instrumental principles) and recent stategies employed to resolve their detaching problems. I show that solving these problems necessitates postulating an indefinitely large number of senses for 'ought'. The semantics for 'ought' that is standard in linguistics offers a unifying strategy for solving these problems, but I argue that an alternative approach combining an end-relational theory (...) of normativity with a comparative probabilistic semantics for 'ought' provides a more satisfactory solution.

While increasing numbers of philosophers have argued for eliminating the retributivist elements of criminal justice systems, their arguments often fall short due to internal inconsistency. Some of the best known of these arguments — such as those provided by Derk Pereboom and Gregg Caruso — rely on the claim that there are moral grounds for rejecting retributivism. In defending this claim, these philosophers typically provide arguments seeking to undermine the type of agent responsibility that they believe is needed to justify (...) retributivism. This is usually followed by an assertion that since the excessive suffering caused by retributivist punishment cannot be justified, it is therefore immoral to preserve remnants of it in our criminal justice systems. This paper — which opposes the moral case against retributivism provided by Pereboom and Caruso, and favors non-moral reasons that recommend rejecting a retributivist approach — is divided into three parts. In part one, I discuss why Pereboom and Caruso are correct in thinking that free will skepticism undercuts the moral justification for retributivism. Part two sets out to explain why their moral case against retributivism fails insofar as it runs afoul of the folk intuitions that are called upon to defend Pereboom’s account of free will skepticism. In part three, I provide a non-moral case against the retributivism that is founded on considerations of self-interest and empathy. (shrink)

In two celebrated and widely-anthologized articles, as well as several books, the biologist Garrett Hardin claims (a) that the world population problem has a certain structure – it is a tragedy of the commons - and, (b) that, given this structure, the only tenable solutions involve either coercion or immense human suffering. In this paper, I shall argue for two claims. First, Hardin’s arguments are deeply flawed. The population problem as he conceives it does not have the structure of a (...) commons; and even if it did, this would not necessitate the extreme responses he canvasses. Second, nevertheless, much of Hardin’s pessimism is justified. Some environmental problems associated with population do have tragic structures, though these are of a different form than Hardin envisions. For example, the problem of global climate change has an intergenerational aspect that makes it importantly worse than Hardin’s commons, and for this reason (as opposed to Hardin’s) extreme responses may be needed to avert environmental catastrophe.

Critics of Hans-Georg Gadamer maintain that his philosophical hermeneutics is unduly conservative: supposedly, Gadamer too readily accepts tradition and too quickly assumes that a text has a unified and understandable meaning. Critics of Jacques Derrida, meanwhile, declare that deconstruction leads to nihilism: if the meaning of every text is undecidable, then a text can mean anything at all - no one meaning is better or worse than any other. And if there is no ground to stand upon, these critics add, (...) then how can we normatively evaluate others? In this essay, I respond to the critics of both Gadamer and Derrida by arguing that philosophical hermeneutics and deconstruction should be understood as complementary postmodern philosophies, as mutually supportive descriptions of the hermeneutic situation. As such, deconstruction counters the charge that philosophical hermeneutics is conservative: instead, a Derridean view uncovers the radical political potential that resides within Gadamer's philosophical hermeneutics. Meanwhile, philosophical hermeneutics counters the charge that deconstruction is nihilistic and cannot support ethical or political critique. A Gadamerian view explains how deconstruction assumes the possibility of understanding meaning and maintaining values that can engender critique. Key Words: deconstruction • Derrida • Gadamer • hermeneutics • justice • philosophical hermeneutics • postmodernism. (shrink)

Recently in these pages it has been argued that a relatively straightforward version of an old argument based on evolutionary biology and psychology can be employed to support the view that innate ideas are a naturalistic source of metaphysical knowledge. While sympathetic to the view that the “evolutionary argument” is pregnant with philosophical implications, I show in this paper how it needs to be developed and deployed in order to avoid serious philosophical difficulties and unnecessary complications. I sketch a revised (...) version of the evolutionary argument, place it in a new context, and show that this version in this context is not vulnerable to the standard criticisms levelled against arguments of this general type. The philosophical import of this version of the argument lies not in any metaphysical conclusions it sanctions directly, but in the support it lends to the metaphilosophy of commonsense. (shrink)

….it [is] wholly irrational to regard as doubtful matters that are perceived clearly and distinctly by the understanding in its purity, on account of mere prejudices of the senses and hypotheses in which there is an element of the unknown.Descartes, Geometrical Exposition of the MeditationsSubstance dualism, once a main preoccupation of Western metaphysics, has fallen strangely out of view; today’s mental/physical dualisms are dualisms of fact, property, or event. So if someone claims to find a difference between minds and bodies (...) per se, it is not initially clear what he is maintaining. Maybe this is because one no longer recognizes ‘minds’ as entities in their own right, or ‘substances.’ However, selves - the things we refer to by use of ‘I’ - are surely substances, and it does little violence to the intention behind mind/body dualism to interpret it as a dualism of bodies and selves. If the substance dualist’s meaning remains obscure, that is because it can mean several different things to say that selves are not bodies. (shrink)

Some philosophers contend that the past must be finite in duration, because otherwise reaching the present would have involved the sequential occurrence of an actual infinity of events, which they regard as impossible. I recently developed a new objection to this finitist argument, to which Andrew Ter Ern Loke and Travis Dumsday have replied. Here I respond to the three main points raised in their replies.

This article argues that inquirers should adopt an active orientation to the limits of their knowledge, an approach referred to as “Transformational Fallibilism”. Drawing on the Popperian tradition, this approach treats the fallibility of knowledge as more than a philosophical nicety, rather seeing the questioning of claims, including those that have been successful, as a key way to improve the understandings of inquirers. This is illustrated with reference to the example of Newtonian and Einsteinian understandings of gravity and time in (...) the natural sciences, and debates about the role of fathers in child-rearing in the social sciences. I compare this approach to that found within critical realism, arguing that while defenders of the latter acknowledge fallibility to some extent, certain of their arguments also place problematic limits on it. Examining Sayer’s work, I argue that his view that practically successful understandings reveal something about the structure of the world involves an overconfidence in these understandings. I suggest that Elder-Vass’s use of the idea of approximate truth involves a similar difficulty. By contrast, I argue for the importance of treating all elements of the understanding, including those bound up with practical successes, as potentially in need of reconstruction at any point.

Alternative splicing allows for the production of many gene products from a single coding sequence. I introduce the concept of alternative splicing via some examples. I then discuss some current hypotheses about the explanatory role of alternative splicing, including the claim that splicing is a significant contributor to the difference in complexity between the human genome and proteosome. Hypotheses such as these bring into question our working concepts of the gene. I examine several gene concepts introduced to cope with processes (...) such as alternative splicing. Next I introduce some hypotheses about the evolution of mechanisms alternative splicing in higher organisms. I conclude that attention to alternative splicing reveals that we adopt an attitude that developmental theorizing must inform evolutionary theorizing and vice versa. (shrink)

Prominent views about representation share a premise: that mathematical communication theory is blind to representational content. Here I challenge that premise by rejecting two common misconceptions: that Claude Shannon said that the meanings of signals are irrelevant for communication theory (he didn't and they aren't), and that since correlational measures can't distinguish representations from natural signs, communication theory can't distinguish them either (the premise is true but the conclusion is false; no valid argument can link them).

When S.C. Dodd concocted the empty formulae for which he is now remembered--as the butt of Sorokin's ridicule--he imagined that he was making a first pass at formulating the laws of social science. Dodd was as serious as Jasso and perhaps a bit more sophisticated and consistent in his choice of philosophical authorities. So one might suppose that Jasso's formulae (1988), which resemble them in certain respects, are subject to the same criticisms. I will argue that Jasso’s formulae are not (...) empty, but that they are also not what Jasso represents them to be. (shrink)

One of Ian C. Jarvie’s most interesting contributions is his discussion of the thinking of Karl Popper and Michael Polanyi on the nature and workings of the scientific community and their relation to politics : 545–564, 2001). The self-image these thinkers contributed to still lingers, but their accounts capture a historical moment that has passed and was idealized even when they were written. In this chapter, I examine this tradition and identify the central themes which dominated this literature and ask (...) the question of how this history is relevant today. The answer will perhaps be surprising: despite the fact that the Left of the past held positions that are the opposites of the positions of the present participatory Left, the considerations that motivated the older Left remain.

This paper publishes a gold ring until recently in private hands in the United States. The former owners, private persons with no scholarly background, brought the ring to the present writer's attention upon learning that he had some knowledge of Greek inscriptions. The one deplorable fact is that this ring was removed from its context, so that much of its scientific value is forever lost to us. Nonetheless, the damage was done by others years ago, and its owners deserve praise (...) for making the ring available for study. The dedicatory inscription on it is an invaluable example of early Argive script. The details of acquisition are unclear. I have been able to ascertain only that the ring was acquired in ancient Mycenae from some Greeks who claimed to have dug it up in the area. As will be seen, in all probability it comes from the Argive Heraion. (shrink)

Skeptical theism is a leading response to the evidential argument from evil against the existence of God. Skeptical theists attempt to block the inference from the existence of inscrutable evils to gratuitous evils by insisting that given our cognitive limitations, it wouldn’t be surprising if there were God-justifying reasons we can’t think of. A well-known objection to skeptical theism is that it opens up a skeptical Pandora’s box, generating implausibly wide-ranging forms of skepticism, including skepticism about the external world and (...) past. This paper looks at several responses to this Pandora’s box objection, including a popular response devised by Beaudoin and Bergmann. I find that all of the examined responses fail. It appears the Pandora’s box objection to skeptical theism still stands. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE DIVINE ATTRIBUTES IN AQUINAS IN THIS PAPER I discuss principally the claim of Aquinas that the divine attribute which is the formal constituent of the divine nature is es.'!e. I also discuss the consequent attribute of simplicity, with some reflections on this relation of consequence. I conclude with some remarks on philosophical realism in general, which I take to be the necessary background to this theory or, as (...) I argue, discovery. * * * In St. Thomas's Summa Theologiae we are confronted first, not with a study of the attributes of God, but with Five Ways of knowing that God exists. Strictly consequent upon this, there are then two basic movements of thought upon which, to mix the metaphor, the next structure after the Five Ways, that of the attributes, is laid. The first step is to find just one attribute which can be put forward as the formal constituent of the divine natura, its essentia (this will be the so-called metaphysical essence, since the real divine essence is one with the simple and hence constituentless divine nature). This is come upon through an immanent logic arising strictly out of conclusions reached through the Five Ways, and is in fact subsisting existence, ipsum esse subsistens, often called Being, confusingly, since this translates ens as well as esse. If it were not this there would be unexplained composition in God, at least between His nature and His act of existing. The second step is then to derive whatever attributes can be strictly deduced from this conception of God as subsistent esse, while a subsidiary step is to divide these into what commentators later called entitative and operative attributes. The first step identifies the nature of God with His aot of existing, 37 38 liTEPHEN THERON actus essendi, stressing that as pure ad He is not in any genus, not to be grasped in an abstract idea, even though the theory of the attributes must go on to say He is truth, is goodness and so on. The saving grace of these attributions, however, is that they do not imply limitation, even though it is a general principle of the Thomistic interpretation of things that form is what places a limitation on being, so that in being a man I cannot be an elephant. Of course the necessary infinity of these absolutely simple perfections entails that each of them is really identical with the divine nature, itself identical with His esse, His actus essendi. There can only be one reality in God, understood as the infinite. But my intention here is not to run through all the well-known arguments yet again. Thus that God, any God, must be subsisting Existence, I take to be well established. We can't have a divine essence capable of receiving existence, and for God to be love, say, He has first to be. I can make no sense of saying that this is merely chosen as appropriate to our way of thinking. I would rather say it thinks itself, once we 'let being be' (Heidegger's inspired definition of thinking). Of course God is not being identified with ens in commune, that almost cynical error of pantheism. God is identified with His own act of existing, proper to Him alone. Since this is, as divine, an act without limitation, we then go on to say that this cannot be an existence shared with any other existing, that God must exist in a uniquely eminent way, that that act of existing which He himself is, is transcendent. In the sense in which God exists, nothing else does, as the doctrine of analogy should bring out rather than obscure.1 Nonetheless, we need to enquire into the significance and implications of it being just existence which is the formal attribute 1 Cf. Leo J. Elders, Die Metaphysik de Thomas von Aquin, I, Salzburg 1985, p. 133: 'Das ens commune ist das geschaffene Seiende...

This paper offers and analysis of Ernest Sosa's Virtue Perspectivism. Although Sosa has been credited with fathering the influential contemporary movement known as Virtue Epistemology, I argue that Sosa imprudently abandons the reliabilist-based insights of Virtue Epistemology in favor of a reflection-based, "perspectival"' view. Sosa's mixed allegiance to reliabilist-based and reflection-based views of knowledge, in fact, leads to an unwelcome tension in his thought which can be relieved by recognizing that his reflection-based view is in fact an account of the (...) cognitive state of understanding, rather than an account of knowledge. Sosa makes matters difficult for himself because he expects too much, as it were, from the concept of knowledge, and in the process burdens his view with elements of reflection it does not require. To solve the problem, I suggest that Sosa needs to develop a two-tiered epistemology which recognizes that knowledge, on the one hand, and understanding, on the other, both have necessary and sufficient conditions unique to themselves.

On one hand people are, by and large, responsible for what they believe , and yet, it seems clear that we have no immediate voluntary control over belief. I argue that it is only psychologically impossible for us to believe things at will. We do, however, have indirect voluntary influence over belief which is sufficient to ground our responsibility for what we believe. Moreover, while we cannot analyze epistemic justification in terms of deontological notions, these notions do underlie our practice (...) of juatifying beliefs to one another. ;In order to further explicate my account I lay out a doxastic practice approach to belief-formation, further exploring this approach through specific areas of believing: perception, trust, interpersonal knowledge. I also explore the connections between belief-formation, power, desire, teleology, value systems, and the emotions. In this discussion I draw especially on the writings of William P. Alston, Alan Millar, Michel Foucault, Friedrich Nietzsche, Harry Frankfurt, Michael Stocker and Robert C. Roberts. ;We can conclude from the discussion that not only are we responsible, by and large, for what we believe, but also that some traditional epistemological traditions are open to question. Particularly we can question criticisms of foundationalism, the unity of the concept of justification, and the separability of ethical realism/anti-realism from realism/anti-realism regarding knowledge.

Abstract: Does the evolving influence of humanity on the Earth’s environment call for new virtues? How might such virtues be seen as contributing to human flourishing? In this paper, I develop Aristotle’s discussion of magnificence and magnanimity to provide a framework within which to discuss such claims. I also defend the controversial view that even if genuinely new virtues may be involved, these may be virtues to which we should not aspire (now, or perhaps ever).

Americans are very grateful to veterans. Veterans are celebrated via speeches, statues, memorials, holidays, and affirmative action. They are lavishly praised in public gatherings and private conversations. Contrary to this widespread attitude, I argue that U.S. citizens should not be very grateful to veterans. In evaluating whether the significant gratitude toward veterans is justified, I begin by exploring the nature of gratitude. On my account, one person should be very grateful to a second person just in case the second person (...) reasonably attempted to provide a significant benefit to the first and was primarily motivated by concern for the first’s well-being. I then look at whether veterans typically satisfy these conditions and argue that they do not. (shrink)

An aim of science is to increase our understanding of the natural world. A primary means for doing so is by providing explanations, which often proceed by tracing the causes of phenomena. How can a causal explanation lead to understanding? While explanations can take many forms, I argue that to succeed they must embody a conception of causation shared with their audience. The challenge then, is to describe this conception and detail its role in explanation. While there is good evidence (...) that scientists employ more than one causal concept, I argue that the concept of productive causation (centered on the notion of bringing about change via a connection) has a primary role in natural science explanations. After critiquing other philosophical accounts, I develop a new theory of productive causation and show how it provides an underpinning for successful explanations. The heart of the theory is a network of persisting processes that possess dispositions toward change-producing mutual interactions. I argue that in a good explanation, the scientific entities, properties and activities invoked will correspond to the theory’s depiction of causal structure. One important dimension of the theory describes how repeated patterns of interaction can give rise to a hierarchy of composite processes. This allows the theory to account for stabilized entities at various spatio-temporal scales. In turn, this enables the approach to be applicable throughout the natural sciences. After starting with simple examples, I show how the theory deals with more challenging cases from physics to biology. I conclude that the approach illuminates how explanations of various forms across diverse disciplines can lead to scientific understanding. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Causality of Prayer and the Execution of Predestination in Thomas AquinasStephen L. BrockIntroduction: The Question of the Reasonableness of Petitionary PrayerIn a lucid and witty essay published in 1945, C. S. Lewis addressed a common objection to the practice of petitionary prayer.1 This practice is not confined to Christianity, of course, but at least in relation to the Christian conception of the deity, it can seem to make (...) little sense. The problem is simple. If God is all-wise and all-good, what is the point of asking him for things? He is already perfectly aware of our true needs, and he already wants to provide for them. Many of our requests are ignorant and misguided, and the others, it seems, will be at best superfluous. Nevertheless, as Lewis observes, petitionary prayer is part of the whole Christian tradition. Jesus himself practiced it, urged his followers to do so, and taught them how. Lewis wanted to explain that the real purpose of the practice is not to inform God of our needs or to twist his arm. Rather, petitionary prayer functions as a kind of cause, a way of bringing things about. It does so by divine institution and as a kind of share in God's own causality. And so understood, it makes perfect sense. I think Lewis is right about this.Another matter, however, is Lewis's particular way of conceiving the causality of petitionary prayer, especially as to its relation to God's own causality and care for the world. I grant that his conception is quite [End Page 15] straightforward and clear, and that it even has a strong initial plausibility. Indeed, I suspect that it gives voice to the way in which many thoughtful people who pray for things conceive of what they are doing. This is why, even though it is not the main focus of the present essay, I think that it serves as a good way of entering to the topic. But I do hope to show that it contains some serious problems.In what follows, I shall first set out Lewis's answer to the question of the reasonableness of petitionary prayer. Then I shall raise one of the problems that I think it faces. This has to do with another attribute that has traditionally been ascribed to the Christian God; namely, omniscience, the knowledge of all things, including all temporal events, past, present, and future. In the essay on prayer, Lewis does not address this problem. But from things that he says elsewhere about temporal events and how God knows them, I think we can gather how he would have solved it.Rather than evaluating this solution myself, I shall turn next to another twentieth-century British thinker, the philosopher Peter Geach. Although Geach agrees with Lewis in ascribing a causal function to petitionary prayer, Geach's way of understanding temporal events and God's knowledge of them contrasts sharply with Lewis's. In fact, Geach argues—I think persuasively—that a position like Lewis's actually ends up making petitionary prayer unable to function as a cause, and therefore renders it pointless. At the same time, however, Geach's own account of how petitionary prayer fits into God's overall plan has something very important in common with Lewis's. And in my opinion, what they have in common is very problematic.This will bring me to my main theme, which is Thomas Aquinas's view of the matter. Like Lewis and Geach, Thomas does regard petitionary prayer as a divinely instituted way of causing things. On their temporal status, his position is similar to Geach's. But on how prayer and its effects fall under God's providential plan, Thomas differs greatly from both authors. I find his account far more satisfactory. Unfortunately, it is also considerably more complicated and philosophically challenging, and my presentation of it will have to be correspondingly longer.The distinctive features of Thomas's view mostly pertain to the metaphysics of divine transcendence. My main task will be to show how, in his account, the full determinacy of God's eternal plan, including that part of it called... (shrink)

Existing institutions do not seem well-designed to address paradigmatically global, intergenerational and ecological problems, such as climate change. 1 In particular, they tend to crowd out intergenerational concern, and thereby facilitate a “tyranny of the contemporary” in which successive generations exploit the future to their own advantage in morally indefensible ways (albeit perhaps unintentionally). Overcoming such a tyranny will require both accepting responsibility for the future and meeting the institutional gap. I propose that we approach the first in terms of (...) a traditional “delegated responsibility” model of the transmission of individual responsibility to collectives, and the second with a call for a global constitutional convention focused on future generations. In this paper, I develop the delegated responsibility model by suggesting how it leads us to understand both past failures and prospective responsibility. I then briefly defend the call for a global constitutional convention. (shrink)

In the second chapter of The descent of man , Charles Darwin interrupted his discussion of the evolutionary origins of language to describe ten ways in which the formation of languages and of biological species were ‘curiously’ similar. I argue that these comparisons served mainly as analogies in which linguistic processes stood for aspects of biological evolution. Darwin used these analogies to recapitulate themes from On the origin of species , including common descent, genealogical classification, the struggle for existence, and (...) natural selection, among others. Skeptical of this interpretation, Gregory Radick sees the naturalistic account of language formation in the Descent comparisons as reinforcing Darwin’s idea that languages and the races of mankind have both undergone progressive development. Yet the details of Darwin’s language–species comparisons, as well as the polemical context in which they appear, show that they were not aimed at so limited a function. Rather, they addressed issues related to species transmutation in general. (shrink)

In their article, Pitron and de Vignemont (2017) provide an insightful and well overdue discussion of the relationship between long-term body representation models and Alice in Wonderland syndrome. Here, I supplement their discussion with a number of observations. First, I present a cautionary note regarding the interpretation of experiential changes in body size as reflective of changes in the content of body representations. Second, I show how their evidence contradicts an alternative model of body representation arising from research into anorexia (...) nervosa—the “LTB” hypothesis. Finally, I highlight a significant issue with their proposed co-construction model. -/- . (shrink)

In my writings on the evidence for postmortem survival. I’ve made no secret of the fact that I consider much of the literature on the subject to be very shabby, usually because the authors are empirically myopic or inferentially-challenged. That is, writers on survival notoriously ignore or treat very superficially relevant areas of research having their own extensive literatures (e.g., on dissociation, savantism, prodigies, gifted under-achievers, and language mastery), and too often they seem unable to formulate valid arguments. In Braude, (...) 2003 I explored these deficiencies in great detail. Here, I’d like simply to comment on a particular class of confusions and a recent eruption of nonsequiturs. (shrink)
