Pickering & Garrod (P&G) consider the possibility that inner speech might be a product of forward production models. Here I consider the idea of inner speech as a forward model in light of empirical work from the past few decades, concluding that, while forward models could contribute to it, inner speech nonetheless requires activity from the implementers.

To be a philosopher of science means, among other things, to have an account of what scientific explanation is, or, at the very least, to have a response to various accounts of scientific explanation on offer from other philosophies of science while earnestly working toward what one hopes will be one’s own, original account. One presumption clearly and often lying behind such work is that science provides two kinds of knowledge. There is propositional knowledge, “knowledge that” or “knowledge what,” and (...) there is some other kind of knowledge, something beyond propositional knowledge, usually called “knowing why.” We can know that the moon will have such a phase at this or that time, that home sales will always slump following a rise in interest rates, or that probably no two snowflakes are the same shape, without knowing why the moon will have that phase, home sales will fall as interest rates rise, or no two snowflakes have the same shape. But science, so the common contemporary presumption continues, fills in the missing knowledge — it tells us why. How science does this, when it can’t, and what the nature of this sort of knowledge is are precisely the issues that separate theorists of explanation. There are, of course, deflationary views of explanation, which reduce explanation to other properties or eliminate explanation altogether , but these are a decided minority. The vast majority of the work on scientific explanation takes itself to be addressing a certain, distinct, kind of knowledge. This is, moreover, a familiar and introductory point made in philosophical discussions of explanation. I rehearse it here because it has a role to play later, in my discussion of Carl Hempel and Paul Oppenheim’s 1948 article, “Studies in the Logic of Explanation”. (shrink)

The first part of the essay explores the relations between the will and practical reason or judgement. The second part takes up decision in the realm of belief, i.e. deciding that such and such is so. This phenomenon raises two questions. Since we decide that as well as to, should we speak of a doxastic will? Secondly, should we regard ourselves as active in the formation of our judgements as in the formation of our intentions? The author's answer to these (...) two further questions is ‘no’ and ‘yes’, respectively: the boundaries between the active and the passive are not marked by the will. (shrink)

L’Homme presents what has been termed Descartes’ “physiological psychology”. It envisions and seeks to explain how the brain and nerves might yield situationally appropriate behavior through mechanical means. On occasion in the past 150 years, this aim has been recognized, described, and praised. Still, acknowledgement of this aspect of Descartes’ writing has been spotty in histories of neuroscience and histories of psychology. In recent years, there has been something of a resurgence. This chapter argues that, in seeking to explain psychological (...) functions such as sense perception, attention, memory, and emotional response, Descartes ascribed a range of active functions to the brain acting on its own (independently of mind).

The authors investigated the ontological argument computationally. The premises and conclusion of the argument are represented in the syntax understood by the automated reasoning engine PROVER9. Using the logic of definite descriptions, the authors developed a valid representation of the argument that required three non-logical premises. PROVER9, however, discovered a simpler valid argument for God's existence from a single non-logical premise. Reducing the argument to one non-logical premise brings the investigation of the soundness of the argument into better focus. Also, (...) the simpler representation of the argument brings out clearly how the ontological argument constitutes an early example of a ?diagonal argument? and, moreover, one used to establish a positive conclusion rather than a paradox.

In the subsequent pages, I want to develop a distinction between wanting and valuing which will enable the familiar view of freedom to make sense of the notion of an unfree action. The contention will be that, in the case of actions that are unfree, the agent is unable to get what he most wants, or values, and this inability is due to his own "motivational system." In this case the obstruction to the action that he most wants to do (...) is his own will. It is in this respect that the action is unfree: the agent is obstructed in and by the very performance of the action. (shrink)

Though Frege was interested primarily in reducing mathematics to logic, he succeeded in reducing an important part of logic to mathematics by defining relations in terms of functions. By contrast, Whitehead & Russell reduced an important part of mathematics to logic by defining functions in terms of relations (using the definite description operator). We argue that there is a reason to prefer Whitehead & Russell's reduction of functions to relations over Frege's reduction of relations to functions. There is an interesting (...) system having a logic that can be properly characterized in relational but not in functional type theory. This shows that relational type theory is more general than functional type theory. The simplification offered by Church in his functional type theory is an over-simplification: one can't assimilate predication to functional application.<br>. (shrink)

My concern in this paper will be to explore and develop a version of nonsocratic skepticism about weakness of will. In my view, socratism is incorrect, but like Socrates, I think that the common understanding of weakness of will raises serious problems. Contrary to socratism, it is possible for a person knowingly to act contrary to his or her better judgment. But this description does not exhaust the common view of weakness. Also implicit in this view is the belief that (...) actions which are contrary to one's better judgment are free in the sense that the agent could have done otherwise. To take seriously the possibility of acting contrary to one's better judgment is at the same time to raise problems about the distinction between weakness and compulsion. I argue that the common view, according to which the differentiating feature is that the weak are able to conform their behavior to their practical judgments, is unjustified. Instead, I have proposed that weakness of will involves the failure to develop certain normal capacities of self-control, whereas compulsion involves desires which even the possession of such capacities would not enable one to resist.

Drawing heavily on recent empirical research to update R.M. Hare's two-level utilitarianism and expand Hare's treatment of "intuitive level rules," Gary Varner considers in detail the theory's application to animals while arguing that Hare should have recognized a hierarchy of persons, near-persons, & the merely sentient.

This book offers a powerful response to what Varner calls the "two dogmas of environmental ethics"--the assumptions that animal rights philosophies and anthropocentric views are each antithetical to sound environmental policy. Allowing that every living organism has interests which ought, other things being equal, to be protected, Varner contends that some interests take priority over others. He defends both a sentientist principle giving priority to the lives of organisms with conscious desires and an anthropocentric principle giving priority to certain very (...) inclusive interests which only humans have. He then shows that these principles not only comport with but provide significant support for environmental goals. (shrink)

The conundrum of the unconstitutional constitution -- The quest for a compelling unity -- The permeability of constitutional borders -- The sounds of silence : militant and acquiescent constitutionalism -- "The first page of the constitution" : family, state, and identity.

With its unique combination of depth, clarity, and humor that has enchanted millions, this beloved classic by bestselling author Gary Zukav opens the fascinating world of quantum physics to readers with no mathematical or technical background. "Wu Li" is the Chinese phrase for physics. It means "patterns of organic energy," but it also means "nonsense," "my way," "I clutch my ideas," and "enlightenment." These captivating ideas frame Zukav's evocative exploration of quantum mechanics and relativity theory. Delightfully easy to read, (...) The Dancing Wu Li Masters illuminates the compelling powers at the core of all we know. (shrink)

Human beings have to ask how faith is possible, in this mixed world of trouble and joy. A safe universe with no scope for adversity would be a mechanical toy, not a creation. A glorious universe will be a place where troubles have eventually been overcome. Christians believe in one God, who is three Persons. God the heavenly Father took the risk of making a real world, full of living people capable of happiness. Jesus Christ, God the Son, came as (...) a human being to take responsibility for creation. He suffered and died; and he rose from death to vindicate the whole enterprise and show that creation can and will be made good. People are not left to work out their own faith but are invited to belong to the church, in order to keep in touch with God the Spirit. They are to behave as God's children, not by rule-bound conformity but by grateful response to the glory of God the Holy Trinity. (shrink)

Resolution is the most widely studied approach to propositional theorem proving. In developing efficient resolution-based algorithms, dozens of variants and refinements of resolution have been studied from both the empirical and analytic sides. The most prominent of these refinements are: DP (ordered). DLL (tree), semantic, negative, linear and regular resolution. In this paper, we characterize and study these six refinements of resolution. We give a nearly complete characterization of the relative complexities of all six refinements. While many of the important (...) separations and simulations were already known, many new ones are presented in this paper: in particular, we give the first separation of semantic resolution from general resolution. As a special case, we obtain the first exponential separation of negative resolution from general resolution. We also attempt to present a unifying framework for studying all of these refinements.

In _Animals and the Limits of Postmodernism_, Gary Steiner illuminates postmodernism's inability to produce viable ethical and political principles. Ethics requires notions of self, agency, and value that are not available to postmodernists. Thus, much of what is published under the rubric of postmodernist theory lacks a proper basis for a systematic engagement with ethics. Steiner demonstrates this through a provocative critique of postmodernist approaches to the moral status of animals, set against the background of a broader indictment of (...) postmodernism's failure to establish clear principles for action. He revisits the ideas of Derrida, Foucault, Nietzsche, and Heidegger, together with recent work by their American interpreters, and shows that the basic terms of postmodern thought are incompatible with definitive claims about the moral status of animals--as well as humans. Steiner also identifies the failures of liberal humanist thought in regards to this same moral dilemma, and he encourages a rethinking of humanist ideas in a way that avoids the anthropocentric limitations of traditional humanist thought. Drawing on the achievements of the Stoics and Kant, he builds on his earlier ideas of cosmic holism and non-anthropocentric cosmopolitanism to arrive at a more concrete foundation for animal rights.

Development of a vaccine for schistosomiasis, a parasitic disease currently affecting over 200 million people worldwide, has been targeted as a priority by the World Health Organisation. Research demonstrating the ability of humans to acquire natural immunity to schistosome infection, together with the successful use of attenuated vaccines in animals both under laboratory and field conditions, suggest that development of a human vaccine is feasible. Attenuated vaccines for schistosomiasis are considered neither safe nor practicable for human use, however, and therefore (...) other approaches must be considered. This review examines progress currently being undertaken in a number of different areas towards achieving the goal of a safe and effective human vaccine for schistosomiasis. (shrink)

Formulations of Anselm’s ontological argument have been the subject of a number of recent studies. We examine these studies in light of Anselm’s text and (a) respond to criticisms that have surfaced in reaction to our earlier representations of the argument, (b) identify and defend a more refined representation of Anselm’s argument on the basis of new research, and (c) compare our representation of the argument, which analyzes that than which none greater can be conceived as a definite description, to (...) a representation that analyzes it as an arbitrary name.

In this paper I discuss two kinds of attempts to qualify incompatibilist and compatibilist conceptions of freedom to avoid what have been thought to be incredible commitments of these rival accounts. One attempt -- which I call soft libertarianism -- is represented by Robert Kane''s work. It hopes to defend an incompatibilist conception of freedom without the apparently difficult metaphysical costs traditionally incurred by these views. On the other hand, in response to what I call the robot objection (that if (...) compatibilism is true, human beings could be the products of design), some compatibilists are tempted to soften their position by placing restrictions on the origins of agency. I argue that both of these attempts are misguided. Hard libertarianism and hard compatibilism are the only theoretical options. (shrink)

The goal of perceptual systems is to allow organisms to adaptively respond to ecologically relevant stimuli. Because all perceptual inputs are ambiguous, perception needs to rely on prior knowledge accumulated over evolutionary and developmental time to turn sensory energy into information useful for guiding behavior. It remains controversial whether the guidance of perception extends to cognitive states or is locked up in a “cognitively impenetrable” part of perception. I argue that expectations, knowledge, and task demands can shape perception at multiple (...) levels, leaving no part untouched. The position advocated here is broadly consistent with the notion that perceptual systems strive to minimize prediction error en route to globally optimal solutions :181–204, 2013). On this view, penetrability should be expected whenever constraining lower-level processes by higher level knowledge is minimizes global prediction error. Just as Fodor feared cognitive penetration of perception threatens theory-neutral observation and the distinction between observation and inference. However, because theories themselves are constrained by the task of minimizing prediction error, theory-laden observation turns out to be superior to theory-free observation in turning sensory energy into useful information.

Theories of language production propose that utterances are constructed by a mechanism that separates linguistic content from linguistic structure, Linguistic content is retrieved from the mental lexicon, and is then inserted into slots in linguistic structures or frames. Support for this kind of model at the phonological level comes from patterns of phonological speech errors. W present an alternative account of these patterns using a connectionist or parallel distributed proceesing (PDP) model that learns to produce sequences of phonological features. The (...) model's errors exhibit some of the properties of human speech errors, specifically, properties that have been attributed to the action of phonological rules, frames, or other structural generalizations.

Josiah Royce, a Johns Hopkins Fellow (1876–1878), polished two manuscripts for publication: "The Spirit of Modern Philosophy" (SMP; 62 pp.), and his dissertation, "The Interdependence of the Principles of Knowledge" (IPK; xi + 332 pp.). Although he penned the texts in blue ink and headers and footnotes in red, he never published either work. SMP—not Royce's 1892 work of the same title—critiqued Francis Bowen's Modern Philosophy from Descartes to Schopenhauer and Hartman, and created a new epistemology. My essay ventures the (...) hypotheses that Royce prudently abstained from publishing SMP to avoid alienating Bowen, a Harvard board-member for faculty admissions, and IPK to avoid advancing an interpretation of Kant he felt unsure of and would later publicly disown. Mainly, however, this paper inquires whether, in drafting SMP, Royce created an outline for IPK. I sketch Royce's life at Hopkins and present context and content of these two MSS. From these I unearth seven philosophical themes running parallel in SMP and IPK. This grounds the paper's major hypothesis that Royce's overriding aim in SMP was less to critique Bowen than to create an outline for the long Introduction and Part One of IPK. (shrink)
