The classical response to Zeno’s paradoxes goes like this: ‘Motion cannot properly be defined within an instant. Only over a period’ (Vlastos.) I show that this ob-jection is exactly what it takes for Zeno to be right. If motion cannot be defined at an instant, even though the object is always moving at that instant, motion cannot be defined at all, for any longer period of time identical in content to that instant. The nonclassical response introduces discontinuity, to evade the (...) paradox of infinite proximity of any point of a distance with any ‘next’. But it introduces the wrong sort of discontinuity because, rather than assuming the discontinuity of motion, as Quantum Theory does, it assumes the discontinuity of space. Due then to the resulting spacetime disorder, though all else is certainly lost, the Tortoise now turns up at least as fast as Achilles and hence not even this much is rescued. Zeno rejects motion because he shows that a moving object must be where it is not. Hence motion, if to occur, must violate the Law of Contradiction (LNC). Applying the concept of quantum discontinuity, I produce an alternative. If an object is to move discontinuously between two boundary points, A and B, what actually obtains is, rather, that it is nowhere at all in-between A and B. And cannot therefore be at two places in-between A and B. And cannot therefore be where it is not. Thus, LNC is conserved. However, in these conditions, the Law of the Excluded Middle (LEM) fails. To mitigate the undesirability of this effect, I show that LEM fails because LNC holds. Thus, the resulting nonbivalent logic, which is also appropriate for quantized transitions of all kinds, will always turn up nonbivalent, because consistent. And this is not too bad, considering.

The paper has two parts: First, I describe a relatively popular thesis in the philosophy of propositional attitudes, worthy of the name ‘taking tense seriously’; and I distinguish it from a family of views in the metaphysics of time, namely, the A-theories (or what are sometimes called ‘tensed theories of time’). Once the distinction is in focus, a skeptical worry arises. Some A-theorists maintain that the difference between past, present, and future, is to be drawn in terms of what exists: (...) growing-block theorists eschew ontological commitment to future entities; presentists, to future and past entities. Others think of themselves as A-theorists but exclude no past or future things from their ontology. The metaphysical skeptic suspects that their attempt to articulate an ‘eternalist’ version of the A-theory collapses into merely ‘taking tense seriously’– a thesis that does not imply the A-theory. The second half of the paper is the search for a stable eternalist A-theory. It includes discussion of temporary intrinsics, temporal parts, and truth. (shrink)

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require an adverbial construal (if they (...) are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.

It is fairly well known that Wittgenstein's criticisms of Russell's multiple‐relation theory of judgement had a devastating effect on the latter's philosophical enterprise. The exact nature of those criticisms however, and the explanation for the severity of their consequences, has been a source of confusion and disagreement amongst both Russell and Wittgenstein scholars. In this paper, I offer an interpretation of those criticisms which shows them to be consonant with Wittgenstein's general critique of Russell's conception of logic and which serves (...) to elucidate some of the notoriously enigmatic passages of the Tractatus. In particular, I seek to show the continuity of Wittgenstein's criticisms of the theory of judgement with his remarks on Russell's paradox and the theory of types. In addition, I place these issues in the context of Russell's own philosophical ambitions in order to reveal the deep divisions between the two over the nature of logical form and the analysis of propositional content.

ABSTRACT What have natural aesthetics and environmentalism in common? Not much if the former deals with nature as if it were an artwork or a gallery of art objects, or if the latter grounds the protection of nature in consequentialist terms. Suppose, however, one adopts a non-consequentialist environmentalism which, further, stakes out a primary view of nature as terrain rather than as habitat; i.e., a view which is not biocentric (life-centred), let alone anthropocentric. This environmentalism is rooted in the belief (...) that we are prima facie bound not to interfere in any of the world undefined by culture whether or not it supports life. There is a reason forbidding us from strip-mining the far side of the moon, say, even though no habitat is thereby destroyed, nor is there any blight creating visual offence to those immediately affected. To furnish the reason for such an ‘acentric’environmentalism, one needs a natural aesthetic. Why? By elimination, because the stock appeals grounding any moral stance—to rights or interests or happiness or autonomy—are unavailable. The ‘subject’of an acentric environmentalism is insensate. But an ‘acentric’aesthetic seems even more curious than its environmentalist dependent. It would entail an aesthetic viewpoint indifferent to human scale and perspective, the very factors which underwrite any cultural aesthetic. So, is such an aesthetic possible? The barest glimpse of how it might look concludes this paper. (shrink)

The examples and concepts that Shoemaker cites are rather heterogeneous. Some distinctions need to be drawn. An optimality thesis involves not just an ordering of options, but a value judgment about them. So let us begin by distinguishing minimality from optimality. And the concept of minimality can play a variety of roles, among which I distinguish between extremum descriptions, statements hypothesizing an optimizing process, and methodological recommendations. Finally, I consider how the three categories relate to Shoemaker’s question that “Who is (...) optimizing: the scientist or nature?” . (shrink)

The most obvious varieties of mental phenomena directed to non- existent objects occur in our experiences of works of art. The task of applying the Meinongian ontology of the non-existent to the working out of a theory of aesthetic phenomena was however carried out not by Meinong by his disciple Stephan Witasek in his Grundzüge der allgemeinen Ästhetik of 1904. Witasek shows in detail how our feelings undergo certain sorts of structural modifications when they are directed towards what does not (...) exist. He draws a distinction between genuine mental phenomena and what he calls `phantasy-material', asserting that `the job of the aesthetic object, whether it is a work of art or a product of nature, is to excite and support the actualisation of phantasy-material in the experiencing subject'. We might think of such phantasy-material as a matter of Ersatz-emotions or emotional `slop'. We could then see Witasek's aesthetics as an elaborate taxonomy of the various different sorts of Ersatz-emotions which the subject allows to be stimulated within himself in his intercourse with works of art, and see works of art themselves as machines for the production of ever more subtle varieties of such phantasy-material in the perceiving subject.

It will be the thesis of this paper that there are among our mental acts some which fall into the category of real material relations. That is: some acts are necessarily such as to involve a plurality of objects as their relata or fundamenta. Suppose Bruno walks into his study and sees a cat. To describe the seeing, here, as a relation, is to affirm that it serves somehow to tie Bruno to the cat. Bruno's act of seeing, unlike his (...) feeling depressed, his putative thinking-about-Santa-Claus or his musing, abstractedly, about the tallest spy, has at least two fundamenta: it is, as a matter of necessity, dependent for its existence upon both Bruno himself and the cat that he sees. This idea will naturally raise echoes of Russell's doctrine of knowledge by acquaintance. 'I am acquainted with an object', Russell tells us, 'when I have a direct cognitive relation to that object, i. e. when I am directly aware of the object itself' (1918, p. 209). And indeed a distinction in many ways like that between acquaintance and description will find a place within the theory here projected, but there are crucial differences. (shrink)

Western society has been diverted from the goal of spiritual freedom and autonomy as expressed in the ancient Pythagorean 'theory of the cosmos'. Indeed, following Heidegger's analysis, it can be seen that modern Western society has arrived at the opposite pole of anthropocentric 'absolute subjectivism' in which the entire non-human world is seen as a material resource to be consumed in the satisfaction of our egoistic passive desires. It is further argued that Spinozism is actually a modern version of the (...) 'theory of the cosmos' which, when supplemented by a vision of man's identity with the ecological world, would provide us with the only adequate portrayal of the God/Nature/Man relationship.

RésuméJohn Searlea récemment soutenu que le cerveau ne peut pas être un ordinateur (non connexionniste). Son argument est que les vrais systèmes physiques comme les cerveaux fonctionnent à la causalité, tandis que les opérations computationnelles ne sont pas causales, mais sont plutôt des séquences formelles qui requièrent un interprète extérieur pour lew existence en tant que systèmes formels. Les vrais systèmes physiques, par contre, ne requièrent aucune interprétation pour lew existence comme systèmes physiques opérationnels.Contrairement à Searle, je soutiens qu'iln'y a (...) pas de démarcation nette entre notre application des formalismes mathématiques standard à des phénomènes physiques comme les oscillations, et notre application des formalismes computationnels aux divers phénomènes physiques qui sont, effectivement ou potentiellement, bien décrits et expliqués pas ces formalismes.

This paper examines the strengths and weaknesses of one of science's most pervasive and flexible metaprinciples;optimalityis used to explain utility maximization in economics, least effort principles in physics, entropy in chemistry, and survival of the fittest in biology. Fermat's principle of least time involves both teleological and causal considerations, two distinct modes of explanation resting on poorly understood psychological primitives. The rationality heuristic in economics provides an example from social science of the potential biases arising from the extreme flexibility of (...) optimality considerations, including selective search for confirming vidence, ex post rationalization, and the confusion of prediction with explanation. Commentators are asked to reflect on the extent to which optimality is an organizing principle of nature, a set of relatively unconnected techniques of science, a normative principle for rational choice and social organization, a metaphysical way of looking at the world, or something else still.

It is a common intuition that I am in a better position to know my own mental states than someone else's. One view that takes this intuition very seriously is Neo-Expressivism, providing a “non-epistemic” account of first-person privilege. But some have denied that we enjoy any principled first-person privilege, as do those who have the Third-Person View, according to which there is no deep difference in our epistemic position with regard to our own and others' mental states. Despite their apparently (...) deep differences, I argue that Neo-Expressivism and the Third-Person View differ in their location of first-person privilege. This difference in the source of first-person privilege allows the key elements of each of these views to be compatible, and can even be combined into a single view about the nature of introspection and self-knowledge. The compatibility of these two views that otherwise appear to be in direct opposition is methodologically significant, highlighting several dialectical lessons that clar.. (shrink)

Russell says that logical constructions are fictions. Does this show that he took them not to be real things?

Russell probes Morgenthau's realist ethics and the underpinnings of the nuclear threat in a technologically evolving modern world with increasingly obsolescent national boundaries.

Despite its internal divisions and the uncertainty surrounding many of its foundations, there is a growing consensus that the on‐going search for an alternative model of the mind finds a minimal theoretical identity in the pursuit of an anti‐Cartesian conception of mental phenomena. Nevertheless, this anti‐Cartesianism remains more or less explicitly committed to the neo‐Brentanian idea that intentionality is an essential feature of the mental—an idea that has prevailed since the advent of modern cognitive science in the 1950s. An issue (...) of compatibility is thereby raised, as neo‐Brentanism arguably sides with cognitive Cartesianism. The main goal of the paper is to put into full light one specific aspect of this largely unperceived problem of compatibility by arguing that the neo‐Brentanian property of intentionality is an essentially representational one that runs counter to the salient anti‐representationalism of anti‐Cartesianism. And, that this representational essence confronts the search for alternative models of the mind of an anti‐Cartesian kind with the following theoretical issue: To what extent is it possible to devise a non‐Brentanian property of intentionality, particularly one that is fully dissociated from the property of representation? This issue is shown to be much deeper and more difficult than it looks once the nature of representation is properly apprehended; it seems to be still waiting for an answer in the current search for an alternative model of the mind, if only because it has not yet be set in fully adequate terms.

Spiritual formation currently lacks a robust epistemology. Christian theology and philosophy often spend more time devoted to an epistemology of propositions rather than an epistemology of knowing persons. This paper is an attempt to move toward a more robust account of knowing persons in general and God in particular. After working through various aspects of the nature of this type of knowledge this theory is applied to specific issues germane to spiritual formation, such as the justification of understanding spiritual growth (...) on an integrative and holistic (heart and mind) model, the reality of hearing God’s voice, and knowing his activity, as well as how such a theory should change the shape of sermons, evangelism, and apologetics.

Bertrand Russell developed a conception of the nature of the visual field, and of other sensory fields, as part of his project of explaining the construction of the external world. Wittgenstein's remarks on the visual field in the Tractatus are in part a response to Russell. Wittgenstein, against Russell, analyses the visual field in terms of facts rather than objects. Further, his conception of the field is, in a distinctive sense, depsychologised.

Ethical reasoning as an action (praxis) as opposed to a knowing (epistemology) strategy is not always effective in guilding ethical, stopping or turning around unethical organizational behavior. In contrast, nonviolent forcing strategies can be very effective, but also destructive. If reasoning is an idealistic thesis and forcing is its pragmatic, material antithesis, then do we need a synthesis action (praxis) strategy such as problem solving negotiating? There are also limitations with negotiating.

For both philosophers and managers, reasoning with ourselves and others can be used both as (1) a way of knowing what is ethical and (2) a way of acting to help ourselves, others and organizations behave ethically. However, for many of us, knowing is frequently not the same as acting. Four areas are addressed: (1) thirteen limitations of ethical reasoning as an action strategy; (2) how a better understanding of these limitations can strengthen ethical reasoning as an action strategy; (3) (...) how an understanding of these limitations can serve as a conceptual foundation for exploring other ethical action strategies; and, (4) implications for experiential learning and teaching.

A comment on Paul Schoemaker's target article in Behavioral and Brain Sciences, 14 (1991), p. 205-215, "The Quest for Optimality: A Positive Heuristic of Science?" (https://doi.org/10.1017/S0140525X00066140). This comment argues that the optimizing model of decision leads to an infinite regress, once internal costs of decision (i.e., information and computation costs) are duly taken into account.

In this paper, I argue that, other things being equal, simpler arguments are better. In other words, I argue that, other things being equal, it is rational to prefer simpler arguments over less simple ones. I sketch three arguments in support of this claim: an argument from mathematical proofs, an argument from scientific theories, and an argument from the conjunction rule.

Between 1896 and 1898 Russell’s philosophy was considerably influenced by Hermann Lotze. Lotze’s influence on Russell was especially pronounced in introducing metaphysical—anthropological, in particular—assumptions in Russell’s logic and ontology. Three steps in his work reflect this influence. (i) The first such step can be discerned in the Principle of Differentiation, which Russell accepted in the Essay (finished in October 1986); according to this Principle, the objects of human cognition are segmented complexes which have diverse parts (individuals). (ii) After Russell reread (...) Lotze in June 1897, he claimed that the solution of the dilemma of pluralism or monism depends on how we see space and time: as relational or as adjectival? (iii) Russell decided for the relational conception only after he attended lectures by McTaggart on Lotze in January to February 1898. The lectures helped Russell to advance (from April to June 1898) a new theory of judgment according to which judgments relate terms (individuals) which are distinct one from another. Space and time moreover are series of moments and places with external relations between themselves. The discussions Russell had with Moore in May to June 1898 took place only after Russell developed this conception; they did not cause his philosophical turn. (shrink)

The idea of evolution functions today as a myth as well as a scientific theory. This use distorts it in some surprising ways. In particular, predictions of the predestined future development of superhumans (Omega Man) are sometimes treated by scientists as if they were an established part of the theory of evolution. Since they rest on the endless–escalator model of evolution, incompatible with Darwinian methods and not separately argued for, they have no standing at all. This phenomenon, and others like (...) it, seem to indicate spiritual needs which are being ignored and thus finding illicit satisfaction. The position is dangerous and needs more attention.

Beginning from an earlier claim of mine that there was really no such area of study as the philosophy of sport, Part One of the paper reconsiders the place previously given to David Best’s distinction between purposive sports and aesthetic sports. In light of a famous cricketing event in the 1977 contest between England and Australia (‘The Ashes’), in which Derek Randall turned a cartwheel after taking the winning catch, the paper clarifies that not all aesthetically-pleasing events taking place in (...) sporting competitions can be understood as the aesthetic in sport. Then, in Part Two, the force of the claim that philosophy is one subject is explored. The conclusion is that a focus just on the philosophy of sport is necessarily inappropriate, since it will present the student with only cases from sport to then apply to sport. Rather, one’s understanding must be informed by (much of) the breadth of philosophy. Charles Travis’s view of occasion-sensitivity provides a clear example of appropriately contextual appeal. Part Three of the paper returns to the need for an institutional account of sport, one recognizing that there is no one occasion on which a particular sport is played; and hence no single set of conditions which can uniquely identify that sport. Thus, soccer played with one’s children typically differs from elite soccer: but both are (genuinely) soccer. When one turns to the appreciation of sport (in the light of Stephen Mumford’s excellent Watching Sport: Aesthetics, Ethics and Emotion [2012a]), one recognizes that, in order to genuinely appreciate sport, one cannot detach oneself from the outcome as completely as Mumford’s extreme purist seems to. But reflection on that case may also return us to contextualism by moving us away from attachments to the complete or the exceptionless in our accounts of spectating as of sport: maybe there is no one thing that occurs in all the relevant cases.

In this article, I argue that an epistemic question about knowledge of our own phenomenal states encourages a certain metaphysical picture of consciousness according to which phenomenal states are reflexive mental representations. Section 1 describes and motivates the thesis that phenomenal self-knowledge is ‘receptive’: that is, the view that a subject has knowledge of their phenomenal states only insofar as they are inwardly affected by those states. In Sections 2 and 3, I argue that this model of phenomenal self-knowledge is (...) unable to accommodate knowledge of our own phenomenology or knowledge of our own awareness. In Section 4, I seek a non-receptive model of phenomenal self-knowledge. I argue that Kriegel’s Self-Representationalist theory of consciousness is uniquely equipped to show how phenomenal self-knowledge is possible. (shrink)
