An interview with Ed Casey where we discuss the intersections of his philosophical work with current political issues, including the Israel-Palestine conflict.

Perceptual experience is often said to be transparent; that is, when we have a perceptual experience we seem to be aware of properties of the objects around us, and never seem to be aware of properties of the experience itself. This is a introspective fact. It is also often said that we can infer a metaphysical fact from this introspective fact, e.g. a fact about the nature of perceptual experience. A transparency theory fills in the details for these two facts, (...) and bridges the gap between them. We have three aims: to scrutinize Michael Tye’s transparency theory :137–151, 2002; Consciousness revisited: materialism without phenomenal concepts, MIT Press, Cambridge, 2009; Philos Stud 170:39–57, 2014a), introduce a new transparency theory, and advance a meta-theoretical hypothesis about the interest, and import, of transparency theories.

[The version of this paper published by Oxford online in 2019 was not copy-edited and has some sense-obscuring typos. I have posted a corrected (but not the final published) version on this site. The version published in print in 2020 has these corrections.] Which is more fundamental, assertion or testimony? Should we understand assertion as basic, treating testimony as what you get when you add an interpersonal addressee? Or should we understand testimony as basic, treating mere assertion -- assertion without (...) testimony -- as what you get when you subtract that interpersonal relation? In this chapter, I’ll argue for the subtractive approach and for the more general thesis that its treatment of the interpersonal element in assertion makes understanding that interpersonal element the key to understanding how assertion expresses belief. My theory of belief-expression in assertion treats it as internalizing the transmission of belief in testimony. How we understand that internalizing move depends on how we conceptualize the interpersonal element in testimony. Since what I’ll call the Command Model does not give us the conceptual resources to make this move, we should adopt an alternative that I’ll call the Custodial Model, on which a testifier aims not to convince her addressee but to reason with him – to give him reasons to believe what she tells him grounded in her trustworthiness in thus attempting to influence him. The subtractive approach to assertion thus rests on a key distinction between the aims of reasoning and persuasion. (shrink)

An assurance theory of trust begins from the act of assurance – whether testimonial, advisorial or promissory – and explains trust as a cognate stance of resting assured. My version emphasizes the risks and rewards of trust. On trust’s rewards, I show how an assurance can give a reason to the addressee through a twofold exercise of ‘normative powers’: (i) the speaker thereby incurs an obligation to be sincere; (ii) if the speaker is trustworthy, she thereby gives her addressee the (...) reason. Each claim is controversial; my contribution lies in how I defend them together, linking the sincerity obligation to the provision of reasons. On trust’s risks, I defend a popular thesis about the nature of trust – that trust differs from mere reliance in how it risks betrayal – against the objection that the thesis ‘moralizes’ trust. Such betrayal need not be moral, I argue, because it may derive entirely from how the assurance purports to provide a reason. (shrink)

According to comparativism, degrees of belief are reducible to a system of purely ordinal comparisons of relative confidence. (For example, being more confident that P than that Q, or being equally confident that P and that Q.) In this paper, I raise several general challenges for comparativism, relating to (i) its capacity to illuminate apparently meaningful claims regarding intervals and ratios of strengths of belief, (ii) its capacity to draw enough intuitively meaningful and theoretically relevant distinctions between doxastic states, and (...) (iii) its capacity to handle common instances of irrationality. (shrink)

This essay comments on the complexity of the task of accommodating Leibniz’s account of relational motion with his dynamics, as evident in Anja Jauernig’s (2008) Leibniz Review article, and suggests some possible strategies for overcoming these obstacles.

Can a reason to believe testimony derive from the addressee’s trust itself or only from reliability in the speaker that the trust perhaps causes? I aim to cast suspicion on the former view, defended by Faulkner, in favor of the latter – despite agreeing with Faulkner’s emphasis on the second-personal normativity of testimonial assurance. Beyond my narrow disagreement with Faulkner lie two broader issues. I argue that Faulkner misappropriates Bernard Williams’s genealogy of testimony when he makes use of Williams’s genealogical (...) argument in his own preferred assurance view of testimony. Though Williams doesn’t clearly articulate it, there is a deep reason why Williams’s genealogy cannot underwrite an argument for trust-based testimonial reasons. Can a genealogical argument underwrite any version of the assurance view? I sketch an assurance view of testimonial reasons that rejects Faulkner’s thesis that such reasons could be grounded in trust. Then I examine what it would take for that assurance view to receive genealogical vindication. (shrink)

This essay explores Kant’s concept of absolute space in the Metaphysical Foundations from the perspective of the development of the relationist interpretation of bodily interactions in the center-of-mass reference frame, a strategy that Huygens had originally pioneered and which Mach also endorsed. In contrast to the interpretations of Kant that stress a non-relationist, Newton-inspired orientation in his critical period work, it will be argued that the content and function of Kant’s utilization of this reference frame strategy places him much closer (...) to Huygens’ relationism than the absolute notions of space and motion favored by Newton and Euler.

In his Edifying Discourses, Soren Kierkegaard published a sermon entitled ‘The Unchangeableness of God’ in which he reiterated the dogma which dominated Catholic, Protestant and even Jewish expressions of classical supernaturalist theology from the first century A.D. until the advent of process theology in the twentieth century. The dogma that as a perfect being, God must be totally unchanging in every conceivable respect was expressed by Kierkegaard in such ways as: He changes all, Himself unchanged. When everything seems stable and (...) in the overturn of all things, He remains equally unchanged; no change touches Him, not even the shadow of a change; in unaltered clearness He, the father of lights, remained eternally unchanged. 1.

This paper identifies three positions on the relationship between language and experience, the third of which I was not acquainted with before from my reading. It seems absurd.

If by “demon” one understands an evil occult being, then its equivalent in the Islamic narrative is the intersection of the category jinn with that of the shayātīn: a demon is a shaytān from among the jinn. The literature in the Islamic tradition on these subjects is vast. In what follows, we will select some key elements from it to provide a brief summary: first on the nature of the jinn, their nature, and their relationship to God and human beings; (...) second, on the origin, nature, and role of Shaytān (Satan himself) and the shayātīn in the moral drama of Islam. Then, we will take a closer look at the relationship between jinn and humankind, according to Islam, and the phenomena of the demonic as it manifests itself in that relation. In the process, I will entertain, tentatively, some philosophical speculation as to the nature of that ultimately mysterious relation and phenomena, drawn from what we find in the religious sources.

How must you think about time when you form an intention? Obviously, you must think about the time of action. Must you frame the action in any broader prospect or retrospect? In this essay I argue that you must: you thereby commit yourself to a specific prospect of a future retrospect – a retrospect, indeed, on that very prospect. In forming an intention you project a future from which you will not ask regretfully, referring back to your follow-through on that (...) intention, “What on earth was I thinking?” I argue that this broader attitude expresses the self-accountability necessary for practical commitment.

This paper examines Descartes' problematic relational theory of motion, especially when viewed within the context of his dynamics, the Cartesian natural laws. The work of various commentators on Cartesian motion is also surveyed, with particular emphasis placed upon the recent important texts of Garber and Des Chene. In contrast to the methodology of most previous interpretations, however, this essay employs a modern "spacetime" approach to the problem. By this means, the role of dynamics in Descartes' theory, which has often been (...) neglected in favor of kinematic factors, is shown to be central to finding a solution to the puzzle of Cartesian motion.

This paper treats two questions about the relation between trust and the will. One question, about trust, is whether you can trust ‘at will.’ Can you trust despite acknowledging that you lack evidence of the trustee’s worthiness of your trust? Another question, about the will, is whether you can exercise your will at all without trust – at least, in yourself. I treat the second question as a guide to the first, arguing that the role of trust in the will (...) reveals how you can trust at will. The key lies in distinguishing two ways of being responsive to evidence. On the one hand, you cannot trust someone – whether another person or your own earlier self – whom you judge unworthy of your trust. On the other hand, trust does not require a positive assessment of trustworthiness. I thus take issue with Pamela Hieronymi’s analysis of trust as a “commitment-constituted attitude.” Your trust is indeed constrained by your responsiveness to evidence of untrustworthiness, but you need undertake no commitment akin to or involving a judgment that the trustee is trustworthy. We can see why trust is not a commitment-constituted attitude by seeing how trust itself plays a role in forming a commitment. (shrink)

This essay explores the possibility of constructing a structural realist interpretation of spacetime theories that can resolve the ontological debate between substantivalists and relationists. Drawing on various structuralist approaches in the philosophy of mathematics, as well as on the theoretical complexities of general relativity, our investigation will reveal that a structuralist approach can be beneficial to the spacetime theorist as a means of deflating some of the ontological disputes regarding similarly structured spacetimes.

I draw attention to how one of Donald Davidson’s arguments against the claim that others have an alternative conceptual scheme does not look compatible with his rejection of analytic truths – how his rejection of the third dogma of empiricism depends on accepting the first. The appendix contests Davidson’s approach to organizing the Pacific Ocean.

In this paper, I present some responses to an argument made by an economist in an online video: that when Britain leaves the European Union, it will be taking many high ranking universities with it, which will lead to an innovation deficit in the union. I present some responses by means of a pastiche of a widely read European fiction writer.

This essay explores the vexed issue of individual corporeal substance in Descartes' natural philosophy. Although Descartes' often referred to individual material objects as separate substances, the constraints on his definitions of matter and substance would seem to favor the opposite view; namely, that there exists only one corporeal substance, the plenum. In contrast to this standard interpretation, however, it will be demonstrated that Descartes' hypotheses make a fairly convincing case for the existence of individual material substances; and the key to (...) this new found individuation is a long neglected set of passages in the Principles of Philosophy.

This article probes the question of what interpretations of quantum mechanics actually accomplish. In other domains, which are briefly considered, interpretations serve to make alien systematizations intelligible to us. This often involves clarifying the status of their implicit ontology. A survey of interpretations of non-relativistic quantum mechanics supports the evaluation that these interpretations make a contribution to philosophy, but not to physics. Interpretations of quantum field theory are polarized by the divergence between the Lagrangian field theory that led to the (...) Standard Model of Particle physics and the Algebraic quantum field theory, that discounts an ontology of particles. Ruetsche's interpretation, it is argued, offers a potential for loosening the sharp polarization that presently obtains. A brief evaluation focuses on the functional ontology of quantum field theory considered as an effective theory. (shrink)

Is autonomy – governing yourself – compatible with letting yourself be governed by trust? This paper argues that autonomy is not only compatible with appropriate trust but actually requires it. Autonomy requires appropriate trust because it is undermined by inappropriate mistrust. An autonomous agent treats herself as answerable for her action-guiding commitments, where answerability requires openness to the rational influence of external, critical perspectives on those commitments. This openness to correction makes one vulnerable to manipulation and can be exploited in (...) ways that undermine autonomy instead of supporting it. We argue that autonomy is undermined by inappropriate trust, and that the inappropriateness lies in the agent’s failure to manifest appropriate responsiveness to evidence of untrustworthiness in the one trusted. The problem isn’t that autonomy requires dispensing with trust but that trust must itself be governed by appropriate responsiveness to evidence of untrustworthiness. Our view confronts two challenges. One challenge lies in explaining why you shouldn’t treat your vulnerability to manipulation as a general reason to let your trusting disposition lapse into an untrusting one. We argue that there is no such general reason to let your responsiveness to evidence of untrustworthiness be supplanted by a suspicious disposition to seek and require positive evidence of trustworthiness. A second, and deeper, challenge arises from the fact that in some especially sophisticated cases of manipulation there is no evidence of untrustworthiness to which you could respond. We argue that you cannot rationally cope with even this unresolvable risk of exploited trust by trusting only yourself. (shrink)

This paper is a response to Kathleen Stock’s book Material Girls, by way of imitation. I have attempted to write a faux chapter in the book’s style, identifying four moments in overcoming the low-high culture divide in responses to the arts.

The object of this paper is not arguments from contingency in general, but specifically Aquinas’s ‘Third Way’ as it appears in his Summa Theologica. I will raise three objections to this argument. First, the argument depends on the premise, that if everything were contingent, then there would have been a time during which nothing exists, but this is not self-evident and no argument is given for it here. Secondly, Aquinas tells us that a key premise in this argument, that an (...) infinite order of things necessary through one another is impossible, has been proven just previously (in the ‘second way’) with respect to an infinite order of efficient causes. But this argument fallaciously equivocates between two different senses of the term ‘first’, and the fallacy does not disappear when applied to the ‘third way’. Thus, Aquinas not only fails, in this argument, to prove the existence of a thing necessary in itself, but fails to prove that anything is necessary at all. Lastly, this argument suffers from a puzzling ambiguity as to the meaning of the term ‘necessity’, and either way of interpreting the term consistently in the argument raises difficulties. (shrink)

The standard representation theorem for expected utility theory tells us that if a subject’s preferences conform to certain axioms, then she can be represented as maximising her expected utility given a particular set of credences and utilities—and, moreover, that having those credences and utilities is the only way that she could be maximising her expected utility. However, the kinds of agents these theorems seem apt to tell us anything about are highly idealised, being always probabilistically coherent with infinitely precise degrees (...) of belief and full knowledge of all a priori truths. Ordinary subjects do not look very rational when compared to the kinds of agents usually talked about in decision theory. In this paper, I will develop an expected utility representation theorem aimed at the representation of those who are neither probabilistically coherent, logically omniscient, nor expected utility maximisers across the board—that is, agents who are frequently irrational. The agents in question may be deductively fallible, have incoherent credences, limited representational capacities, and fail to maximise expected utility for all but a limited class of gambles.

Among the most popular strategies for justifying political obligations are those that appeal to the principle of fairness. These theories face the challenge, canonically articulated by Robert Nozick, of explaining how it is that persons are obligated to schemes when they receive goods that they do not ask for but cannot reject. John Simmons offers one defense of the principle of fairness, arguing that people could be bound by obligations of fairness if they voluntarily accept goods produced by a cooperative (...) scheme. Simmons, however, thinks that such a theory will do little work in justifying political obligations, since virtually no one voluntarily accepts state goods. This paper attempts to advance just such a theory by arguing that states are in fact genuine cooperative schemes and that Simmons is overly pessimistic in his appraisal of whether the majority of citizens accept the goods provided by their states.

This paper engages two debates about trust, deriving from two distinct questions about the nature of trust. The first asks how to define trust. Does trusting B to φ involve anything more than relying on B to φ? The second asks about the normative structure of trust. Does trust most fundamentally embody a two-place or a three-place relation? I’ll defend a new position in the second debate that yields an equally new position in the first. The standard three-place model highlights (...) ‘A trusts B to φ.’ The two-place model prefers ‘A trusts B.’ On my new three-place model, both are less fundamental than ‘A φs through trust in B.’ We do, of course, trust people to do things. But the most fundamental form of trust lies in doing something through trust in a person. I call this the Assurance View of trust because I’ll argue that trusting involves accepting another’s invitation to trust – an assurance, in effect, that the other is relevantly trustworthy. Trust thereby differs from mere reliance by how it makes available a reason to rely on the trusted. In mere reliance, your reason to rely on B is exogenous to the reliance relation, emerging, for example, from B’s track record of relevant reliability. When you trust B, by contrast, you take yourself to have a reason to rely on B that is endogenous to your trust, a reason grounded not merely in B’s reliability, exogenously considered, but in B’s ongoing responsiveness to your relevant needs. The Assurance View’s key insight emerges, I’ll argue, from cases wherein trust is disappointed – the trusted does not do what you trusted her to do – yet not thereby betrayed. (shrink)

This is a sketch of the basis and role of consciousness and the minimally required elements and constraints of any setting that may produce consciousness. It proposes that consciousness (as we know it) is a biologically-mediated product of evolved recursive and hierarchically nested representational systems that obey information theoretic principles and Bayesian (probabilistic) feedback and feedforward predictive modeling processes.

This is a conjecture about the conditions and operating structures that are required for the phenomenality of certain mental states. Specifically, full-blown phenomenality is assumed, as contrasted with constrained examples of phenomenal experience such as sensations of color and pain. Propositional attitudes and content, while not phenomenal per se, are standardly concurrent and may condition phenomenal states (e.g., when tied to false beliefs). It is conjectured that full phenomenality natively arises in coherent processes of situated sensory synthesis and representation (with (...) conceptual content) that are looped, mereologically whole and multi-dimensional. And that phenomenal states are typically phase-states within a parameterized conjoint structure of world and experiencer processes that are causally modulated across Markov blankets (which are conditionally independent and may be nested: cf. M. Kirchoff, et. al., 2017, 2018; and T. Burge, 2010, re: anti-individualism). Though they may, it is not accepted that phenomenally conscious states must be targets of higher-order representations (cf. A. Byrne, 2004). (shrink)

Plotinus’ famous treatise against the Gnostics (33), together with contemporary and thematically related treatises on Intelligible Beauty (31), on Number (34), and on Free Will and the Will of the One (39), can be seen as providing the essential components of a Plotinian defense of polytheism against conceptual moves that, while associated for him primarily with Gnostic sectarians overlapping with Platonic philosophical circles, will become typical of monotheism in its era of hegemony. When Plotinus’ Gnostics ‘contract’ divinity into a single (...) God, they not only devalue the cosmos for its multiplicity and diversity, but also multiply intelligible principles unreasonably. This is because they have foreclosed the distinction, which is to become increasingly explicit in the later antique Platonists, between the intelligible and that which is given existentially, the domain belonging to Plotinus’ indeterminate multiplicity of ‘intelligible Gods’, as opposed to the dialectically determinate number of intelligible principles. Plotinus is prescient in recognizing that incipient monotheism threatens to erase the distinction between philosophy and theology, and between both of these and psychology, the final outcome of which can only be solipsism or nihilism. The defense of polytheism is seen in this fashion to be essential to the preservation of the space for philosophical discourse. (shrink)

Influenced by Martha Kuhlman, I am disposed to read Milan Kundera as personally disliking crowds. But I speculate that there is a practical reason for his writing against crowds, if we see him as part of a system of novelists.

It’s a popular idea that memory resembles testimony insofar as each can ‘preserve’ epistemic warrant. But how does such ‘preservation’ do its epistemic work? I have elsewhere developed an assurance theory of testimonial warrant. Here, I develop an assurance theory of preservative memory. How could the ‘preservation’ of warrant through memory work through an assurance? What would even count as an intrapersonal assurance? I explain each form of preservation by contrasting the relation that preserves warrant with a pathological alternative. My (...) assurance theory of testimony theorizes the illocutionary norms governing the speech act of telling by explaining what goes wrong when there’s what Austin calls an ‘abuse.’ But what norms govern an intrapersonal memory relation? There are two sides in a memory relation: the earlier self judges that p, then memory keeps the later self in epistemic touch with that judgment by ‘preserving’ its warrant. But this is not an illocutionary relation. (When you ‘tell yourself that p,’ you are trying to ‘convince yourself’ that p and as such typically do not yet even judge that p.) I argue that the earlier self nonetheless offers an assurance by extending an invitation to trust. Your earlier self judges that p in part by projecting a future in which you will continue to trust yourself on the question whether p when you lose access to the evidence that informed the judgment. That projection of trust in yourself posits a worthiness of trust that ought to lead others to accept your testimony that p. Assurance in memory and assurance in testimony thus ought to work together. This aspect of the parallel emerges vividly when we see how it breaks down in the pathology of gaslighting – more than merely illocutionary abuse! – which targets specifically how testimony and memory work together in inviting trust relations.

George Bernard Shaw did various things to make his essays readable, such as using short sections. In this paper, I raise the worry that they are at risk of being replaced by vocabulary and sayings from folk culture.

The article investigates the treatment of modality in chapters 12 and 13 of De Interpretatione and gives a new interpretation of the puzzling table of modals to be found at the beginning of chapter 13, as well as dealing with some of Aristotle’s puzzles. This is achieved by extending Aristotle’s distinction between two senses of possibility, which (following Ackrill) I call ‘one-sided’ and ‘two-sided’, to the two notions of necessity and impossibility. The conclusion is reached that, while the two notions (...) of necessity and impossibility are logically incompatible when both are taken as one-sided, in their two-sided senses they are in fact equivalent.

I identify two seemingly good reasons for obscure writing, one to do with avoiding plagiarism or near-plagiarism (which I have identified before), and the other to do with avoiding attracting readers who prefer accessible writing but nevertheless have no space for you in the structure of roles they envisage.

Henry Sidgwick raises a problem for the doctrine that all citizens have a right to as much freedom from intervention as possible, which begins with the observation that surely there is no intention to apply it to children. The writings of George Bernard Shaw suggest a solution to this problem, which I believe is now forgotten and which I in turn convey here.

Shashi Tharoor criticizes R.K. Narayan in the following way: “Narayan’s prose was like a bullock-cart: a vehicle that can move only in one gear, is unable to turn, accelerate or reverse, and remains yoked to traditional creatures who have long since been overtaken.” I think there is a quick defence, which is that it is very unlikely that one can write the different kinds of works he did without being able to significantly change pace; but there is an objection from (...) Joseph Conrad criticism. (shrink)

This paper tries to formulate the paradox of organic solidarity more precisely and propose a solution.

This paper examines the debate between Marilyn Strathern and I.C. Jarvie. Writing in 1987, Strathern argues that the time is ripe for reincorporating Sir James Frazer. Jarvie thinks Strathern does so in a way that treats revolutions in anthropology as not involving scientific progress. There is a familiar defence against this charge while pursuing the same, or much the same, line of argument.

This paper gives further feedback in response to the evening of presentations about the value of different disciplines to the social sciences, at the University of Manchester.

This paper attempts to provide a clearer formulation of the paradox presented by Annette B. Weiner, in terms of a requirement to keep certain objects within a social group and also a requirement to exchange them with another social group.

The 2004-5 essay competition set by the Federal Reserve Bank of Minneapolis asks, “Why are some countries rich and some countries poor?” It has information which strangely does not feature the name Amartya Sen. But I have conceived of a defence against the charge that this is bad practice, which resembles appealing to the descriptivist theory of names.

I raise the question of whether there is a hidden source of doubt in Descartes’ first meditation, if one adopts the perspective of some people he describes as insane.

Abstract: In Vacco v. Quill, 521 U.S. 793 (1997), the Supreme Court for the first time in American case law explicitly applied the principle of double effect to reject an equal protection claim to physician-assisted suicide. Double effect, traced historically to Thomas Aquinas, proposes that under certain circumstances it is permissible unintentionally to cause foreseen evil effects that would not be permissible to cause intentionally. The court rejected the constitutional claim on the basis of a distinction marked out by the (...) principle, i.e., between directly intending the death of a terminally ill patient as opposed to merely foreseeing that death as a consequence of medical treatment. The Court held that the distinction comports with fundamental legal principles of causation and intent. Id. at 802. -/- Critics allege that the principle itself is intrinsically flawed and that, in any event, its employment in Vacco is without legal precedent. I argue in response to contemporary objections that double effect is a valid principle of ethical reflection (Part II); claims to the contrary notwithstanding, double effect analysis is a pervasive, albeit generally unacknowledged principle employed regularly in American case law (Part III); and drawing on the preceding two sections, Vacco's application of the principle of double effect is appropriate (Part IV). -/- My conclusion is that [o]peration of some form of the principle, by whatever name, is inevitable. In an imperfect world where duties and interests collide, the possibility of choices of action foreseen to have both good and evil consequences cannot be avoided. In rare circumstances, ethics and the law require that a person refrain from acting altogether. More often, however, they provide that a determination of whether an actor may pursue a good effect although knowing it will or may unintentionally cause an harmful effect requires a more complex analysis - a double effect analysis. -/- Keywords: Equal protection, double effect, intention, physician-assisted suicide, Constitutional Law, Bioethics.

Milan Kundera is now perhaps the greatest living philosopher, but he suffers from logical problems. One might propose that since he is a person who works primarily in the medium of fiction, one should not be too harsh on him, rather find ways to make him more logical. The result may be rather chaste.

Inference is a powerful tool; after all, it generally plays a central role in the activity of thinking. But the process of making an inference is not universally correctly applied, nor is it always understood. The rules of inference are capable of misapplication, in the sense that we sometimes infer 'too much', or might infer something which is qualitatively different from the premises we have started with. Certain kinds of inference, or inferences drawn from certain kinds of phenomena or certain (...) kinds of premise, are misleading or incorrect. And not every inference is an inference validly drawn. Invalid inferences are the result of one of two errors: firstly, an error resulting from an incorrect premise, or a premise whose meaning is uncertain or unclear; or secondly, an error which is the consequence of the incorrect application of the rules of inference. The purpose of this short book is to consider a number of these types of error. Much of the book's subject matter comprises the areas of philosophical discussion which the author encountered during a programme of undergraduate study at the University of Oxford. (shrink)
