I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide mere continuum idealizations (...) and by reason of this circumstance conceal the information-theoretic source from which they derive. (4) No element in the description of physics shows itself as closer to primordial than the elementary quantum phenomenon, that is, the elementary device-intermediated act of posing a yes-no physical question and eliciting an answer or, in brief, the elementary act of observer-participancy. Otherwise stated, every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit. (shrink)

Epistemic reasons are mental states. They are not propositions or non-mental facts. The discussion proceeds as follows. Section 1 introduces the topic. Section 2 gives two concrete examples of how our topic directly affects the internalism/externalism debate in normative epistemology. Section 3 responds to an argument against the view that reasons are mental states. Section 4 presents two problems for the view that reasons are propositions. Section 5 presents two problems for the view that reasons are non-mental facts. Section 6 (...) argues that reasons are mental states. Section 7 responds to objections. (shrink)

In this essay I show how to reconcile epistemic invariantism with the knowledge account of assertion. My basic proposal is that we can comfortably combine invariantism with the knowledge account of assertion by endorsing contextualism about speech acts. My demonstration takes place against the backdrop of recent contextualist attempts to usurp the knowledge account of assertion, most notably Keith DeRose's influential argument that the knowledge account of assertion spells doom for invariantism and enables contextualism's ascendancy.

Conceptualism is the thesis that, for any perceptual experience E, (i) E has a Fregean proposition as its content and (ii) a subject of E must possess a concept for each item represented by E. We advance a framework within which conceptualism may be defended against its most serious objections (e.g., Richard Heck's argument from nonveridical experience). The framework is of independent interest for the philosophy of mind and epistemology given its implications for debates regarding transparency, relationalism and representationalism, demonstrative (...) thought, phenomenal character, and the speckled hen objection to modest foundationalism.

One fairly common view about practical reason has it that whether you have a reason to act is not determined by what you know, or believe, or are justified in believing. Your reasons are determined by the facts. Perhaps there are two kinds of reasons, and however it goes with motivating reasons, normative reasons are determined by the facts, not your take on the facts. One fairly common version of this view has it that what's reasonable for you to do (...) is determined by what you know or believe. Any view that drives this kind of wedge between reasons and rationality is inherently unstable. I argue against this view, criticize the arguments typically presented in its favor, and sketch an alternative. (shrink)

This article accomplishes two closely connected things. First, it refutes an influential view about the relationship between perception and knowledge. In particular, it demonstrates that perceiving does not entail knowing. Second, it leverages that refutation to demonstrate that knowledge is not the most general factive propositional attitude.

I argue that you can have a priori knowledge of propositions that neither are nor appear necessarily true. You can know a priori contingent propositions that you recognize as such. This overturns a standard view in contemporary epistemology and the traditional view of the a priori, which restrict a priori knowledge to necessary truths, or at least to truths that appear necessary.

Argumentations are at the heart of the deductive and the hypothetico-deductive methods, which are involved in attempts to reduce currently open problems to problems already solved. These two methods span the entire spectrum of problem-oriented reasoning from the simplest and most practical to the most complex and most theoretical, thereby uniting all objective thought whether ancient or contemporary, whether humanistic or scientific, whether normative or descriptive, whether concrete or abstract. Analysis, synthesis, evaluation, and function of argumentations are described. Perennial philosophic (...) problems, epistemic and ontic, related to argumentations are put in perspective. So much of what has been regarded as logic is seen to be involved in the study of argumentations that logic may be usefully defined as the systematic study of argumentations, which is virtually identical to the quest of objective understanding of objectivity.

This book treats ancient logic: the logic that originated in Greece by Aristotle and the Stoics, mainly in the hundred year period beginning about 350 BCE. Ancient logic was never completely ignored by modern logic from its Boolean origin in the middle 1800s: it was prominent in Boole’s writings and it was mentioned by Frege and by Hilbert. Nevertheless, the first century of mathematical logic did not take it seriously enough to study the ancient logic texts. A renaissance in ancient (...) logic studies occurred in the early 1950s with the publication of the landmark Aristotle’s Syllogistic by Jan Łukasiewicz, Oxford UP 1951, 2nd ed. 1957. Despite its title, it treats the logic of the Stoics as well as that of Aristotle. Łukasiewicz was a distinguished mathematical logician. He had created many-valued logic and the parenthesis-free prefix notation known as Polish notation. He co-authored with Alfred Tarski’s an important paper on metatheory of propositional logic and he was one of Tarski’s the three main teachers at the University of Warsaw. Łukasiewicz’s stature was just short of that of the giants: Aristotle, Boole, Frege, Tarski and Gödel. No mathematical logician of his caliber had ever before quoted the actual teachings of ancient logicians. -/- Not only did Łukasiewicz inject fresh hypotheses, new concepts, and imaginative modern perspectives into the field, his enormous prestige and that of the Warsaw School of Logic reflected on the whole field of ancient logic studies. Suddenly, this previously somewhat dormant and obscure field became active and gained in respectability and importance in the eyes of logicians, mathematicians, linguists, analytic philosophers, and historians. Next to Aristotle himself and perhaps the Stoic logician Chrysippus, Łukasiewicz is the most prominent figure in ancient logic studies. A huge literature traces its origins to Łukasiewicz. -/- This Ancient Logic and Its Modern Interpretations, is based on the 1973 Buffalo Symposium on Modernist Interpretations of Ancient Logic, the first conference devoted entirely to critical assessment of the state of ancient logic studies.

Plato is associated with the idea that the body holds us back from knowing ultimate reality and so we should try to distance ourselves from its influence. This sentiment appears is several of his dialogues including Theaetetus where the flight from the physical world is compared to becoming like God. In some major dialogues of Plato's later career such as Philebus and Laws, however, the idea of becoming like God takes a different turn. God is an intelligent force that tries (...) to create order in the physical world. I argue that likeness to God in these dialogues involves imitating God's effort by trying to order our bodies, souls, and societies as intelligence directs. Becoming like Plato's God is not to abandon the world. It is to improve it. (shrink)

Thirteen meanings of 'implication' are described and compared. Among them are relations that have been called: logical implication, material implication,deductive implication, formal implication, enthymemic implication, and factual implication. In a given context, implication is the homogeneous two-place relation expressed by the relation verb 'implies'. For heuristic and expository reasons this article skirts many crucial issues including use-mention, the nature of the entities that imply and are implied, and the processes by which knowledge of these relations are achieved. This paper is (...) better thought of as an early stage of a dialogue than as a definitive treatise. (shrink)

In this essay, we suggest practical ways to shift the framing of crisis standards of care toward disability justice. We elaborate on the vision statement provided in the 2010 Institute of Medicine (National Academy of Medicine) “Summary of Guidance for Establishing Crisis Standards of Care for Use in Disaster Situations,” which emphasizes fairness; equitable processes; community and provider engagement, education, and communication; and the rule of law. We argue that interpreting these elements through disability justice entails a commitment to both (...) distributive and recognitive justice. The disability rights movement's demand “Nothing about us, without us” requires substantive inclusion of disabled people in decision‐making related to their interests, including in crisis planning before, during, and after a pandemic like Covid‐19.

What is the relation between works of fiction and the acquisition of knowledge?

Infinitists argue that their view outshines foundationalism because infinitism can, whereas foundationalism cannot, explain two of epistemic justification’s crucial features: it comes in degrees and it can be complete. I present four different ways that foundationalists could make sense of those two features of justification, thereby undermining the case for infinitism.

Worrall argued that structural realism provides a ‘synthesis’ of the main pro-realist argument – the ‘No Miracles Argument’, and the main anti-realist argument – the ‘Pessimistic Induction’. More recently, however, it has been claimed that each of these arguments is an instance of the same probabilistic fallacy – sometimes called the ‘base-rate fallacy’. If correct, this clearly seems to undermine structural realism and Magnus and Callender have indeed claimed that both arguments are fallacious and ‘without [them] we lose the rationale (...) for … structural realism ’. I here argue that what have been shown to be fallacious are simply misguided formalisations of ‘the’ arguments and that when they are properly construed they continue to provide powerful motivation for favouring structural realism.

One question about the role of the mental in the determination of practical reason concerns the pro-attitudes: can any set of beliefs, without the help of a desire, rationalize or make reasonable a desire, intention, attempt, or intentional action? After criticizing Michael Smith’s argument for a negative answer to this question, I present two arguments in favor of a positive answer. Another question about the role of the mental in the determination of practical reason concerns belief: what gives you a (...) reason to go to the store, the fact that you’re out of milk or the belief that you’re out of milk? The two questions about the mental are connected. I argue that if we give a positive answer to the first question and reject the Humean Theory of Motivation, we cannot accept the currently favored conception of normative reasons as determined by the facts. For the anti-Humean, normative reasons must be determined by the agent’s perspective. (shrink)

An encyclopedic article on epistemic supervenience in Blackwell companion to epistemology, 2 ed.

This paper clarifies and evaluates a premise of William Alston’s argument in Perceiving God. The premise in question: if it is practically rational to engage in a doxastic practice, then it is epistemically rational to suppose that said practice is reliable. I first provide the background needed to understand how this premise fits into Alston’s main argument. I then present Alston’s main argument, and proceed to clarify, criticize, modify, and ultimately reject Alston’s argument for the premise in question. Without this (...) premise, Alston’s main argument fails. (shrink)

1. The restless mind[1] Like us, early modern philosophers, both natural and moral, didn’t always understand the springs of their own actions. They didn’t want to feel everything they felt, and couldn’t trace the sources of all their thoughts and imaginings. Events from past experience come to mind again unwilled: abstract thought is interrupted by fantastical images, like the ‘winged horses, fiery dragons, and monstrous giants’ by which Hume exemplified ‘the liberty of the imagination’[2]. Then, as now, a failure to (...) keep a train of thought on track could be blamed for both personal and social ills, for wasted lives and erratic policies. The ongoing struggle to distinguish the deliverances of reason from what Hume called ‘the loose and indolent reveries of a castle-builder’ (1739/ 1978, p.624) thus required scrutiny of daydream and fancy as much as belief and knowledge (see also Tierney- Hynes 2007 on the ‘castle-builder’). The mind’s tendencies to float and to roam were of great interest to early modern philosophers as well as to others concerned with medicine, mental health, morals, education, and taste. This paper sketches one local line of thinking and theorizing about ‘mind-wandering’ and its bodily causes in British philosophy over the first decades of the 18th century, as a small exemplar of a form of cognitive history intended to illuminate independent historical and contemporary concerns about our understanding of mental life. The dual aim is to see problems in our historical material that we might otherwise miss, and to use history to explore phenomena more or less marginalized by modern psychology[3]. (shrink)

In Anarchy, State and Utopia, Robert Nozick argues, first, that free-market anarchism is unstable -that it will inevitably lead back to the state; and, second, that without a certain "redistributive" proviso, the model is unjust. If either of these things is the case, the model defeats itself, for its justification purports to be that it provides a morally acceptable alternative to government (and therefore to the state). I argue, against Nozick's contention, that his "dominant protection agency" neither meets his monopoly (...) condition for statehood nor need run afowl of his redistributive requirement. This being the case, his argument against free market anarchism fails. (shrink)

There is a problem regarding God and perception right at the heart of Berkeley ’s metaphysics. With respect to this problem, I will argue for : It is intractable. Berkeley has no solution to this problem, and neither can we hope to offer one on his behalf.

Draft version of essay. ABSTRACT: Benjamin Whichcote developed a distinctive account of human nature centered on our moral psychology. He believed that this view of human nature, which forms the foundation of “Cambridge Platonism,” showed that the demands of reason and faith are not merely compatible but dynamically supportive of one another. I develop an interpretation of this oft-neglected and widely misunderstood account of human nature and defend its viability against a key objection.

Realistic uses of Virtual Reality technology closely integrate user training on virtual objects with VR-assisted user interactions with real objects. This paper shows how the Interactive Theory of Perception may be extended to cover such cases. Virtual objects are explained as concrete models that have an inner generation mechanism, and the ITP is used to explain how VR users can both perceive such local CMs, and perceptually represent remote real objects. Also, concepts of modeling and representation are distinguished. The paper (...) concludes with suggestions as to how the ITP methodology developed here could be extended to iconic external representations and models generally. (shrink)

The new philosophy of superdeterminism is a specific approach to answering fundamental questions about existence, knowledge, and morality based on a single scientific fact about the universe, namely that cause and effect in physics are not real. In 2020, Swedish theoretical physicist, Dr. Johan Hansson published a physics proof that our universe is superdeterministic meaning a predetermined static block universe without cause and effect in physics. A new philosophy of superdeterminism based on this scientific discovery that cause and effect are (...) not real has many important implications for human beings, but one especially important implication is a disproof of existentialism. The major tenets of existentialism cannot be true in the absence of cause and effect in physics, such as the existence of free will or freedom of choice, the lack of predetermined human behavior, the absurdity of life in the face of the inevitability of death, and the meaninglessness of existence, life and the universe.

In a recent very interesting and important challenge to tracking theories of knowledge, Williams & Sinhababu claim to have devised a counter-example to tracking theories of knowledge of a sort that escapes the defense of those theories by Adams & Clarke. In this paper we will explain why this is not true. Tracking theories are not undermined by the example of the backward clock, as interesting as the case is.

A counterfactual is a conditional statement in the subjunctive mood. For example: If Suzy hadn’t thrown the rock, then the bottle wouldn’t have shattered. The philosophical importance of counterfactuals stems from the fact that they seem to be closely connected to the concept of causation. Thus it seems that the truth of the above conditional is just what is required for Suzy’s throw to count as a cause of the bottle’s shattering. If philosophers were reluctant to exploit this idea prior (...) to 1970, it was because of a widespread feeling that the truth-conditions of the counterfactual conditional were not sufficiently well understood. The development of a formal semantics for counterfactuals by Robert Stalnaker [1968] and David Lewis [1973b] stands as a major recent achievement in philosophical logic. (shrink)

This paper investigates the meaning of the neo-Confucian concept of 'li'. From early on, it has the sense of a pattern designating how things are and ought to be. But it takes on the appearance of something transcendent to the world only at a certain point in history, when it becomes juxtaposed to 'qi'. Zhu Xi has been criticized for this 'li-qi' dichotomization and the transcendentalization of 'li'. The paper re-examines this putative dualism and transcendentalism, looking into both Zhu's discussions (...) and pre- and post-Zhu discussions of 'li', and concludes it to be an inter-connective threading immanent to the world.

This article further explains and develops a recent, comprehensive semantic naturalization theory, namely the interactive indexing (II) theory as described in my 2008 Minds and Machines article Semantic Naturalization via Interactive Perceptual Causality (Vol. 18, pp. 527–546). Folk views postulate a concrete intentional relation between cognitive states and the worldly states they are about. The II theory eliminates any such concrete intentionality, replacing it with purely causal relations based on the interactive theory of perception. But intentionality is preserved via purely (...) abstract propositions about the world that index, or correlate with, appropriate cognitive states. Further reasons as to why intentionality must be abstract are provided, along with more details of an II-style account of representation, language use and propositional attitudes. All cognitive representation is explained in terms of classification or sorting dispositions indexed by appropriate propositions. The theory is also related to Fodor’s representational theory of mind, with some surprisingly close parallels being found in spite of the purely dispositional basis of the II theory. In particular, Fodor’s insistence that thinking about an item cannot be reduced to sorting dispositions is supported via a novel two-level account of cognition—upper level propositional attitudes involve significant intermediate processing of a broadly normative epistemic kind prior to the formation of sorting dispositions. To conclude, the weak intentional realism of the II theory—which makes intentional descriptions of the world dispensable—is related to Dennett’s ‘intentional stance’ view, and distinguished from strong (indispensable) intentional realist views. II-style dispositions are also defended. (shrink)

Commercial lawyers working across borders know that globalization has changed commercial law. To think of commercial law as only the law of states is to have an inadequate understanding of the norms governing commercial transactions. Some have argued for a transnational conception of commercial law, but their grounds of justification have been unpersuasive, often grounded on claims about the common content among national legal systems. Legal positivism is a rich literature on the concept of a legal system and the validity (...) conditions for rules in legal systems, but it has not been used to understand legal order outside or beyond the state. This article aims to use legal positivism to conceptualize a transnational commercial law order. Prevailing positivist accounts at least implicitly condition legal order on state sovereignty. The article offers a cosmopolitan conception of legal positivism, in which the state is no longer an enabling condition for law. The cosmopolitan conception provides the means by which to adequately describe a transnational commercial law order. There are limits to the conceptual analysis this article provides, one of which is that it does not purport to evaluate the justice or morality of transnational legal order. But the cosmopolitan conception of legal positivism elucidated in this article stands on its own as a way of understanding a number of transnational legal orders other than commercial law. The attractiveness of the account is that it describes law as a human social practice even when it is not solely the product of the state, so that we do not have to rely on natural law theories to understand legal rules that states do not maintain.

The collaborative projects described in this e-book have already produced thrilling new danceworks, new technologies, and innovative experimental methods. As the papers collected here show, a further happy outcome is the emergence of intriguing and hybrid kinds of writing. Aesthetic theory, cognitive psychology, and dance criticism merge, as authors are appropriately driven more by the heterogeneous nature of their topics than by any fixed disciplinary affiliation. We can spy here the beginnings of a mixed phenomenology and ethnography of dance practice (...) and choreographic cognition, which is deeply informed and empirically inspired by the best current theory in the sciences of the embodied mind [footnote 1]. These sciences must themselves increasingly deal with culture and cognition all at once: questions about pleasure in movement, habit and skill, and kinaesthetic memory, for example, require neuroscientific, physiological, psychological, sociological, and anthropological investigation simultaneously. These then are essentially collaborative enterprises, and the active interpenetration of the concerns of dance practitioners and academic researchers is one remarkable success of Unspok en Knowledges and Conceiving Connections.

The philosophy of superdeterminism is based on a single scientific fact about the universe, namely that cause and effect in physics are not real. In 2020, accomplished Swedish theoretical physicist, Dr. Johan Hansson published a physics proof using Albert Einstein’s Theory of Special Relativity that our universe is superdeterministic meaning a predetermined static block universe without cause and effect in physics. Some believe that the lack of cause and effect in physics would cripple science, but this is an absurd notion (...) given the fact that science has already been enormously successful in the absence of cause and effect in physics. Because the philosophy of superdeterminism is founded on a single scientific fact, then any of the implications of this philosophy are also rooted in science. The role of science under the philosophy of superdeterminism is the same as it has always been namely to understand the universe and offer technological solutions to the world’s problems. The philosophy of superdeterminism offers a means of harmonizing the belief in God and science for over half the world’s population by supporting the existence of God and the notion of bodily resurrection in the afterlife through inferences based on the science of physics.

Artworks have at least some necessary content properties, as do abstract entities such as propositions. But no concrete item, whether an object, event, process etc., could have any necessary content property. So no artwork could be identical with a concrete item. Hence artworks must be abstract. I also argue that artworks are only contingently connected with concrete items, just as propositions are only contingently linked to their linguistic tokens.

Peter H.

The philosophy of superdeterminism is based on a single scientific fact about the universe, namely that cause and effect in physics are not real. In 2020, accomplished Swedish theoretical physicist, Dr. Johan Hansson published a physics proof using Albert Einstein’s Theory of Special Relativity that our universe is superdeterministic meaning a predetermined static block universe without cause and effect in physics. Consequently, all your future behaviors and thoughts must also be predetermined and already exist in a future portion of the (...) static dimension of time in our block universe. Because consciousness must be an aspect of physical reality, then the physical reality of the brain must be capable of producing your subjective experience of the world. Our conscious subjective experience of ourselves and the world around us is a construct of our own brain’s neural network containing ideas and concepts representing the physical reality of the world and ourselves. Moreover, our conscious minds must exist at all points in our existence within our block universe whether our past, present or future selves, because our block universe always exists because nothing within physics can cause our universe not to exist in the absence of cause and effect in physics. One should be concerned with every moment of your conscious life to guard against conscious experiences you would not want endlessly repeated in our block universe. (shrink)

This sequel to Exploring Maori Values develops the idea that humans can and need to become 'people of the land' in the Maori sense, developing a harmonious interdependence with the environment in which we live rather than continuing to dominate it. Although arising out of Maori concepts, this is a model for human life which is available to any culture.

A picture provides both configurational content concerning its design features, and recognitional content about its external subject. But how is this possible, since all that a viewer can actually see is the picture's own design? I argue that the most plausible explanation is that a picture's design has a dual function. It both encodes artistically relevant design content, and in turn that design content encodes the subject content of the picture--producing overall a double content structure. Also, it is highly desirable (...) that a resulting double content theory for pictures should be closely integrated with a related double content account of perceptual content generally, so as to avoid suspicions of ad hoc theorizing that would apply only to pictorial content. The resulting theory should also be able to explain the inevitable ambiguities involved in abstracting two levels of visual content from a single visible surface, as well as explaining the systematic relations between the two kinds of content. I provide an orientational theory--based on a recently developed spatial logic of orientational concepts--for this purpose, and show how depictive and perceptual content in general can be usefully explained in these orientational terms. This account of picturing also integrates well with a previously developed, more generic double content theory of art, and it is also plausible in cognitive science terms. (shrink)

The most important voices concerning the changes now occurring in Central and Eastem Europe are those that come from within, for those voices are informed not only by indifferent data and objective reports, but by personal hopes, fears, desires and needs. Without careful consideration of what such voices say, judgment can only be sterile. Furthermore, policy decisions made without the benefit of the intemal perspective are likely to be flawed, and ineffectual. Policies won’t work if they do not take into (...) account the point of view of those who are supposed to be affected by them. There nevertheless remains an important role for outsiders to play in the discussion of the impact of political change on the future of philosophical thought, especially if the outside perspective can serve as a test of the internal view.

Memory is a set of cognitive capacities by which humans and other animals retain information and reconstruct past experiences, usually for present purposes. Philosophical investigation into memory is in part continuous with the development of cognitive scientific theories, but includes related inquiries into metaphysics and personal identity.

While I strongly agree with Patrick Grim that abstract relationships are real, and that it is possible to get them right, the danger that we will get them wrong is just as real. The use of visual representation of abstract phenomena, precisely because of our predilection to see patterns in everything and because we don't have to think so hard about visible representations generally, may lead us to see things that aren't there.

Leo Strauss’ reading of al-Farabi is a meditation on the issue of how philosophers speak beyond their time and place. They must speak in such a way that they can be understood by the enlightened but avoid persecution by the vulgar masses. According to Strauss, al-Farabi recognized that the philosopher can be happy in the imperfect city democratic city because of its freedom of thought, while the masses can be truly happy only in the virtuous city. This leads him to (...) consider the possible role for the philosopher to advise the "enlightened prince" and to participate in the manipulation of the beliefs of the masses toward some enlightened goal – what we are now witnessing in our think-tank politics. But if we consider a truer reading of al-Farabi’s philosophy, it in many ways recognizes the importance of imperfections, ambivalences, and frontiers. Our intellectual and religious ideals are often beyond our reach – Plato’s “city in speech” – but yet these ideals can orient us and give us a sense of place even in our imperfect situations. For al-Farabi, the democratic city is the best of the imperfect cities, because its imperfections and freedoms allow for new possibilities. Today most of us live in this imperfect city, but this is precisely what allows us to maintain our connections with the past, and project many possibilities for the future. And it is what allows this conference to take place. (shrink)

The initial argument presented herein is not significantly original—it is a simple reflection upon a notion of computation originally developed by Putnam and criticised by Chalmers et al. .

If correct the resulting bold philosophical claim is that phenomenal states—such as feelings and visual experiences—can never be understood or explained functionally. (shrink)

Actual situations where folk philosophy might have predicted precognition effects were studied and dealt with experimentally and theoretically. Extremely strong experimental results were obtained but the findings supported not precognition but the Many Bubble Interpretation, which uses at this time dynamical systems theory as applied to the physics of the brain.
