In this paper I introduce a sequent system for the propositional modal logic S5. Derivations of valid sequents in the system are shown to correspond to proofs in a novel natural deduction system of circuit proofs (reminiscient of proofnets in linear logic, or multiple-conclusion calculi for classical logic). -/- The sequent derivations and proofnets are both simple extensions of sequents and proofnets for classical propositional logic, in which the new machinery—to take account of the modal vocabulary—is directly motivated in terms (...) of the simple, universal Kripke semantics for S5. The sequent system is cut-free and the circuit proofs are normalising. (shrink)

The idea that fictions may educate us is an old one, as is the view that they distort the truth and mislead us. While there is a long tradition of passionate assertion in this debate, systematic arguments are a recent development, and the idea of empirically testing is particularly novel. Our aim in this chapter is to provide clarity about what is at stake in this debate, what the options are, and how empirical work does or might bear on its (...) resolution. We distinguish between merely influencing people’s opinions and providing genuine learning, where the latter requires that the source of the change in opinion should be reliable. Other important ideas here are the extent to which authors of fiction may be considered to provide testimony, or something like it, and the possibility of recognizing an unstated purpose in the project of the fictional work. We ask whether fictions can furnish us not merely with ideas but with reasons for believing them, perhaps by constituting thought experiments. We consider whether the focus should be on understanding rather than on knowledge, and whether fictions can inform us about the qualities of another’s experiences. We briefly describe some experimental work of recent decades and suggest that the evidence for learning from fiction is currently meagre. (shrink)

The language of rights pervades modern social and political discourse and yet there is deep disagreement amongst citizens, politicians and philosophers about just what they mean. Who has them? Who should have them? Who can claim them? What are the grounds upon which they can be claimed? How are they related to other important moral and political values such as community, virtue, autonomy, democracy and social justice? In this book, Duncan Ivison offers a unique and accessible integration of, and (...) introduction to, the history and philosophy of rights. He focuses especially on the politics of rights: the fact that rights have always been, and will remain, deeply contested. He discusses not only the historical contexts in which some of the leading philosophers of rights formed their arguments, but also the moral and logical issues they raise for thinking about the nature of rights more generally. At each step, Ivison also considers various deep criticisms of rights, including those made by communitarian, feminist, Marxist and postmodern critics. The book is aimed at students and readers coming to these issues for the first time, but also at more knowledgeable readers looking for a distinctive integration of history and theory as applied to questions about the nature of rights today.

In an attempt to determine the epistemic status of computer simulation results, philosophers of science have recently explored the similarities and differences between computer simulations and experiments. One question that arises is whether and, if so, when, simulation results constitute novel empirical data. It is often supposed that computer simulation results could never be empirical or novel because simulations never interact with their targets, and cannot go beyond their programming. This paper argues against this position by examining whether, and under (...) what conditions, the features of empiricality and novelty could be displayed by computer simulation data. I show that, to the extent that certain familiar measurement results have these features, so can some computer simulation results. (shrink)

We present a new frame semantics for positive relevant and substructural propositional logics. This frame semantics is both a generalisation of Routley–Meyer ternary frames and a simplification of them. The key innovation of this semantics is the use of a single accessibility relation to relate collections of points to points. Different logics are modeled by varying the kinds of collections used: they can be sets, multisets, lists or trees. We show that collection frames on trees are sound and complete for (...) the basic positive distributive substructural logic $\mathsf {B}^+$, that collection frames on multisets are sound and complete for $\mathsf {RW}^+$ (the relevant logic $\mathsf {R}^+$, without contraction, or equivalently, positive multiplicative and additive linear logic with distribution for the additive connectives), and that collection frames on sets are sound for the positive relevant logic $\mathsf {R}^+$. The completeness of set frames for $\mathsf {R}^+$ is, currently, an open question. (shrink)

This paper defends Flatland—the view that there exist neither determination nor dependence relations, and that everything is therefore fundamental—from the objection from explanatory inefficacy. According to that objection, Flatland is unattractive because it is unable to explain either the appearance as of there being determination relations, or the appearance as of there being dependence relations. We show how the Flatlander can meet the first challenge by offering four strategies—reducing, eliminating, untangling and omnizing—which, jointly, explain the appearance as of there being (...) determination relations where no such relations obtain. Since, plausibly, dependence relations just are asymmetric determination relations, we argue that once we come mistakenly to believe that there exist determination relations, the existence of other asymmetries (conceptual and temporal) explains why it appears that there are dependence relations.

William Lane Craig’s God over All argues against the kind of “divine conceptualism” about abstract objects which I defend. In this conference presentation I note several points of agreement with and appreciation for Craig’s important work. I then turn to five points of critique and response pertaining to: the sovereignty-aseity intuition, the reality of false propositions, God’s having “inappropriate” thoughts, propositions being purely private and incommunicable, and a consistent view of God’s own ontological commitments. I conclude by summarizing our two (...) key differences, indicating that we may have much more in common than first appears. (shrink)

The two principal models of design in methodological circles in architecture—analysis/synthesis and conjecture/analysis—have their roots in philosophy of science, in different conceptions of scientific method. This paper explores the philosophical origins of these models and the reasons for rejecting analysis/synthesis in favour of conjecture/analysis, the latter being derived from Karl Popper’s view of scientific method. I discuss a fundamental problem with Popper’s view, however, and indicate a framework for conjecture/analysis to avoid this problem.

In the distribution of resources, persons must be respected, or so many philosophers contend. Unfortunately, they often leave it unclear why a certain allocation would respect persons, while another would not. In this paper, we explore what it means to respect persons in the distribution of scarce, life-saving resources. We begin by presenting two kinds of cases. In different age cases, we have a drug that we must use either to save a young person who would live for many more (...) years or an old person who would only live for a few. In different numbers cases, we must save either one person or many persons from certain death. We argue that two familiar accounts of respect for persons―an equal worth account, suggested by Jeff McMahan, and a Kantian account, inspired by the Formula of Humanity―have implausible implications in such cases. We develop a new, “three-tiered” account: one that, we claim, generates results in such cases that accord better with many people’s considered judgments than those produced by its rivals. (shrink)

I am aware of the rain outside, but only in virtue of looking at a weather report. I am aware of my friend, but only because I hear her voice through my phone. Thus, there are some things that I’m aware of, but only indirectly. Many philosophers believe that there are also some things of which I am directly aware. The most plausible candidates are experiences such as pains, tickles, visual sensations, etc. In fact, the philosophical consensus seems to be (...) that experiences are the only plausible candidates for acquaintance. But I will argue that we are also acquainted with ourselves. After outlining what it means to be acquainted with oneself, I will introduce, develop, and defend a commonly used test for acquaintance. Then I will apply this test to us and show that we pass. I will consider various objections to my argument. But ultimately I will conclude that we can be, and often are, acquainted with ourselves.

A powerful argument against the counterfactual comparative account of harm is that it cannot distinguish harming from failing to benefit. In reply to this problem, I suggest a new account of harm. The account is a counterfactual comparative one, but it counts as harms only those events that make a person occupy his level of well-being at the world at which the event occurs. This account distinguishes harming from failing to benefit in a way that accommodates our intuitions about the (...) standard problem cases. In laying the groundwork for this account, I also demonstrate that rival accounts of harm are able to distinguish harming from failing to benefit only if, and because, they also appeal to the distinction between making upshots happen and allowing upshots to happen. One important implication of my discussion is that preserving the moral asymmetry between harming and failing to benefit requires a commitment to the existence of a metaphysical and moral distinction between making and allowing.

This paper reviews six attempts to give cooperative solutions to Prisoners Dilemmas: symmetry (agents are in identical situations, so should choose the same way, so should both choose cooperation because that’s better for each), mechanism (each agent should delegate the decision to a machine which will choose cooperation for them provided the other does likewise), inducement (the agents should make a side bet which pays off only upon both cooperating), resolution (each agent should resolve to cooperate, then act on the (...) resolution), alternative principle (rationality requires not dominance reasoning and so defecting, but constrained maximization or resolution compliance or “sophisticated” choosing, and so cooperation), and preference revision (each agent should acquire conditional preferences to cooperate, then cooperate provided the other agent has acquired similar preferences). It distinguishes one-stage from two-stage games, as well as endogenously available solutions (ones available to agents in the circumstances of the game merely due to the nature of rationality) from solutions requiring exogenous devices. It contrasts Edward McClennen’s endogenous solution, which is some combination of resolution and alternative principle solution, with David Gauthier’s endogenous alternative principle solution. It argues that all have problems, ones best solved by the endogenous preference revision solution defended by Duncan MacIntosh. (shrink)

Community has been both celebrated and demonized as a fortress that shelters and defends its members from being exposed to difference. Instead of abandoning community as an antiquated model of relationships that is ill suited for our globalized world, this book turns to the writings of Giorgio Agamben, Roberto Esposito, and Jean-Luc Nancy in search for ways to rethink community in an open and inclusive manner. Greg Bird argues that a central piece of this task is found in how (...) each philosopher rearticulates community not as something that is proper to those who belong and improper to those who are excluded or where inclusion is based on one’s share in common property. We must return to the forgotten dimension of sharing, not as a sharing of things that we can contain and own, but as a process that divides us up and shares us out in community with one another. This book traces this problem through a wide array of fields ranging from biopolitics, communitarianism, existentialism, phenomenology, political economy, radical philosophy, and social theory.

The function or intended use of a device such as a fire escape is escape from fire, whether or not it is ever actually used as such or it acquires other uses. Biological function, on the other hand, depends, in one way or another, on actual use. Philosophical attempts to explain artifact function by analogy with biological function or to build a unified theory of function are nonetheless common. What such attempts routinely overlook, however, is the role of forethought in (...) intentional function. I defend the traditional intended use view of function, emphasize the role of forethought and argue that design intentions are rationally grounded in a design brief, for which there is no obvious natural analogue.

I argue that Hobbes isn't really a materialist in the early 1640s (in, e.g., the Third Objections to Descartes's Meditations). That is, he doesn't assert that bodies are the only substances. However, he does think that bodies are the only substances we can think about using imagistic ideas.

The paper is an examination and critique of the philosophy of science fiction horror of seminal American horror, science fiction and fantasy writer H.P. Lovecraft (1890-1937). Lovecraft never directly offers a philosophy of science fiction horror. However, at different points in his essays and letters, he addresses genres he labels “interplanetary fiction”, “horror”, “supernatural horror”, and “weird fiction”, the last being a broad heading covering both supernatural fiction and science fiction. Taken together, a philosophy of science fiction horror emerges. Central (...) to this philosophy is the juxtaposition of the mysterious, unnatural and alien against a realistic background, in order to produce the emotion that Lovecraft calls “cosmic fear”. This background must not only be scientifically accurate, but must accurately portray human psychology, particularly when humans are faced with the weird and alien. It will be argued that Lovecraft’s prescriptions are overly restrictive and would rule out many legitimate works of science fiction horror art. However, he provides useful insights into the genre.

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

Postcolonial Liberalism presents a compelling account of the challenges to liberal political theory by claims to cultural and political autonomy and land rights made by indigenous peoples today. It also confronts the sensitive issue of how liberalism has been used to justify and legitimate colonialism. Ivison argues that there is a pressing need to re-shape liberal thought to become more receptive to indigenous aspirations and modes of being. What is distinctive about the book is the middle way it charts between (...) separatism, on the one hand, and assimilation, on the other. These two options present a false dichotomy as to what might constitute a genuinely postcolonial liberal society. In defending this ideal, the book addresses important recent debates over the nature of public reason, justice in multicultural and multinational societies, collective responsibility for the past, and clashes between individual and group rights.

Grey zone attacks tend to paralyze response for two reasons. First, they present us with choice scenarios of inherently dilemmatic structure, e.g., Prisoners’ Dilemmas and games of chicken, complicated by difficult conditions of choice, such as choice under risk or amid vagueness. Second, they exploit our uncertainty about how much we do or should care about the things under attack¬—each attack is small in effect, but their effects accumulate: how should we decide whether to treat a given attack as something (...) meriting a serious response rather than a mere irritation to be ignored? This chapter brings standard decision theoretic tools to bear on the issues, tools such as the maximization of expected utility principle, and the precautionary principle. But it also develops three innovations. It shows that seeing it as possible to make choices not just of actions given our values, but also choices of values themselves, can extricate us from certain kinds of decision paralysis. It shows how we can rationally regard ourselves as having bright decision lines even when nothing in the circumstance of choice has these lines in its structure. And it shows how certain conflict escalation risks from the former two strategies can be managed by both parties seeing that cooperation can yield a sharable surplus of goods, and that cooperation can be rational upon a rationally defensible change in their values so that each comes to derive utility from the success of both parties. This yields cooperative solutions to what amount to Prisoners’ Dilemmas. The Cold War was prosecuted on the logic of strategic rationality and that part of game theory that is deterrence theory. We need a new logic from decision theorists for the games that constitute grey zone conflict. (shrink)

We present and defend the Australian Plan semantics for negation. This is a comprehensive account, suitable for a variety of different logics. It is based on two ideas. The first is that negation is an exclusion-expressing device: we utter negations to express incompatibilities. The second is that, because incompatibility is modal, negation is a modal operator as well. It can, then, be modelled as a quantifier over points in frames, restricted by accessibility relations representing compatibilities and incompatibilities between such points. (...) We defuse a number of objections to this Plan, raised by supporters of the American Plan for negation, in which negation is handled via a many-valued semantics. We show that the Australian Plan has substantial advantages over the American Plan. (shrink)

Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

Science fiction fandoms tend to contain significant numbers of fans who feel angry and resentful about the handling of the franchise they are fans of, because of the stories the franchises owners have told. The paper addresses the question of when, if ever, such anger and resentment are justified. Special attention will be paid to Star Trek fandom, but other fandoms will be considered, including those for Star Wars and Doctor Who. Various proposed justifications for anger and resentment will be (...) considered, including that franchise owners have misled fans about the stories they would tell, have wasted opportunities to produce good art, have reduced the value of older art, have engaged in a form of cultural appropriation by repurposing old characters, have caused needless offense of a sort akin to the offense of religious sensibilities, have offended against the principle of utility, and have taken advantage of unjust copyright laws. The paper does not champion a conclusion about when, if ever, fan anger and resentment are justified. However, it is concluded that, contrary to what is often assumed, it is not obvious that fan anger and resentment are always unjustified, and so fan anger and resentment cannot always be dismissed out of hand.

As a contribution to a wider discussion on moral discernment in theological anthropology, this paper seeks to answer the question “What is the impact of mental illness on an individual’s ability to make moral decisions?” Written from a clinical psychiatric perspective, it considers recent contributions from psychology, neuropsychology and imaging technology. It notes that the popular conception that mental illness necessarily robs an individual of moral responsibility is largely unfounded. Most people who suffer from mental health problems do not lose (...) the capacity to make moral decisions, and mental illness on its own rarely explains anti-social or criminal behaviour. Moreover, the assumptions of some scientists, that recent developments in neuropsychology and brain imaging suggest biological determinism, must be treated with caution. (shrink)

As I walk into a restaurant to meet up with a friend, I look around and see all sorts of things in my immediate environment—tables, chairs, people, colors, shapes, etc. As a result, I know of these things. But what is the nature of this knowledge? Nowadays, the standard practice among philosophers is to treat all knowledge, aside maybe from “know-how”, as propositional. But in this paper I will argue that this is a mistake. I’ll argue that some knowledge is (...) constituted, not by beliefs toward propositions, but by awareness of properties and objects. Seeing isn’t believing, but it is knowing. After further characterizing this type of knowledge, I will make the case for it. Then I will consider a variety of objections. Finally, I will indicate how our recognition of this knowledge may answer other questions, and solve other problems, in philosophy. (shrink)

This paper discusses the materialist views of Margaret Cavendish, focusing on the relationships between her views and those of two of her contemporaries, Thomas Hobbes and Henry More. It argues for two main claims. First, Cavendish's views sit, often rather neatly, between those of Hobbes and More. She agreed with Hobbes on some issues and More on others, while carving out a distinctive alternative view. Secondly, the exchange between Hobbes, More, and Cavendish illustrates a more general puzzle about just what (...) divided materialists from their opponents. Seemingly straightforward disagreements about whether incorporeal substances exist turn out to be more complex ones in which the nature of those things is disputed at the same time as their existence.

David Gauthier thinks agents facing a prisoner's dilemma ('pd') should find it rational to dispose themselves to co-operate with those inclined to reciprocate (i.e., to acquire a constrained maximizer--'cm'--disposition), and to co-operate with other 'cmers'. Richmond Campbell argues that since dominance reasoning shows it remains to the agent's advantage to defect, his co-operation is only rational if cm "determines" him to co-operate, forcing him not to cheat. I argue that if cm "forces" the agent to co-operate, he is not acting (...) at all, never mind rationally. Thus, neither author has shown that co-operation is rational action in a pd. (shrink)

It is argued that standard accounts of the epistemology of religious commitmentfail to be properly sensitive to certain important features of the nature of religious conviction. Once one takes these features of religious conviction seriously, then it becomes clear that we are not to conceive of the epistemology of religious conviction along completely rational lines.But the moral to extract from this is not fideism, or even a more moderate proposal that casts the epistemic standing of basic religious beliefs along nonrational (...) lines. Rather, one needs to recognise that in an important sense religious convictions are not beliefs at all, but that this is compatible with the idea that many other religious commitments are beliefs. This picture of the nature of religious commitment is shown to fit snugly with the Wittgensteinian account of hinge commitments, such that all rational belief essentially presupposes certain basic arational hinge commitments, along lines originally suggested by John Henry Newman. We are thus able to marshal a parity-style argument in defence of religious commitment. Although religious belief presupposes basic arational religious convictions, it is not on this score epistemically amiss since all belief presupposes basic arational convictions, or hinge commitments. The resulting view of the epistemology of religious commitment is a position I call quasi-fideism. (shrink)

If one can get the targets of one's current wants only by acquiring new wants (as in the Prisoner's Dilemma), is it rational to do so? Arguably not. For this could justify adopting unsatisfiable wants, violating the rational duty to maximize one's utility. Further, why cause a want's target if one will not then want it? And people "are" their wants. So if these change, people will not survive to enjoy their wants' targets. I reply that one rationally need not (...) advance one's future wants, only current ones. Furthermore, rational choice seeks not utility (the co-obtaining of a want and its target), but satisfaction (the eventual obtaining of what is now wanted) -- otherwise, it would be irrational to care now about what happens after one dies. Finally, persons survive "rational" changes of values. Thus reflection on the rational revision of values illuminates the conditions on personal identity and the bases and aims of rational choice.

I can be aware of myself, and thereby come to know things about myself, in a variety of different ways. But is there some special way in which I—and only I—can learn about myself?

They deny that the self shows up in experience. However, in this paper I appeal to research on schizophrenia—on thought insertion, (...) in particular—to argue that Hume and his follows are wrong: The self does, in fact, show up in experience.

This is an introduction to my edited book, the Research Handbook on Liberalism (2024). Some chapters tackle broad, meta-level questions about the coherence and justificatory limits and possibilities of liberalism; others tackle conceptual issues; still others, specific institutional, cultural, historical, and political questions. This introductory chapter is intended to provide a general orientation to these discussions, but also highlight some recurring themes and challenges facing liberalism in an era of rampant inequality, illiberalism, rising autocracies, populism, and massive technological change. I (...) provide a taxonomy of five different kinds of liberalism in play in the field, along with three overarching challenges discussed in the book - the apparent insufficiency, complacency, and self-undermining nature of liberalism. Can contemporary liberalism survive? It can, but not without clearly grasping some of the fundamental challenges it faces today. (shrink)

Gassendi and Hobbes knew each other, and their approaches to philosophy often seem similar. They both criticized the Cartesian epistemology of clear and distinct perception. Gassendi engaged at length with skepticism, and also rejected the Aristotelian notion of scientia, arguing instead for a probabilistic view that shows us how we can move on in the absence of certain and evident knowledge. Hobbes, in contrast, retained the notion of scientia, which is the best sort of knowledge and involves causal explanation. He (...) thought, however, that this sort of knowledge was only available in geometry and political philosophy. (shrink)

What does the 'colonialist' reading of Locke's political theory suggest about the relationship between liberalism and colonialism in general, as well as the pre-history of liberalism in particular?

The two most common accounts of the category of relation are the "toothpick" account of relations and the inherent attribute view of relations. In this essay, I present and defend another traditional account of relations, according to which they are neither real things in their own right nor inherent attributes of things. Instead, they are creatures of reason grounded in objective, non-relational attributes of things. I illustrate this view by reference to the major classes of relations that have some claim (...) to be real or objective - grounded in being. In an appendix, I use this account to discuss what it means to say that the persons of the Trinity are "substantial relations.". (shrink)

For the tradition, an action is rational if maximizing; for Gauthier, if expressive of a disposition it maximized to adopt; for me, if maximizing on rational preferences, ones whose possession maximizes given one's prior preferences. Decision and Game Theory and their recommendations for choice need revamping to reflect this new standard for the rationality of preferences and choices. It would not be rational when facing a Prisoner's Dilemma to adopt or co-operate from Amartya Sen's "Assurance Game" or "Other Regarding" preferences. (...) But there are preferences which it maximizes to adopt and co-operate from. (shrink)

Leibniz's mill argument in 'Monadology' 17 is a well-known but puzzling argument against materialism about the mind. I approach the mill argument by considering other places where Leibniz gave similar arguments, using the same example of the machinery of a mill and reaching the same anti-materialist conclusion. In a 1702 letter to Bayle, Leibniz gave a mill argument that moves from his definition of perception (as the expression of a multitude by a simple) to the anti-materialist conclusion. Soon afterwards, in (...) the Preface to the New Essays, Leibniz gave a different mill argument. That argument depends upon there being no arbitrary and inexplicable connections in nature, because God would not create such things. Later, in the 'Monadology', Leibniz again used the mill example in arguing against materialism. That passage too, I argue, uses an argument from inexplicability rather than from Leibniz's definition of perception. (shrink)

“We are animals.” That’s what animalists say—that’s their slogan. But what animalists mean by their slogan varies. Many animalists are adamant that what they mean—and, indeed, what the true animalist thesis is—is that we are identical to animals (human animals, to be precise). But others say that’s not enough. They say that the animalist thesis has to be something more—perhaps that we are essentially or most fundamentally human animals. This paper argues that, depending on how we understand it, animalism is (...) either false or uninteresting. If animalism is just the claim that we are identical to animals, then it is uninteresting. For it doesn’t provide an answer to the question it’s meant to address. On the other hand, if animalism entails a stronger claim, such as that we are essentially animals, then animalism is false. Either way, we should set animalism aside. (shrink)

A common epistemological assumption in contemporary bioethics held b y both proponents and critics of non-traditional forms of cognitive enhancement is that cognitive enhancement aims at the facilitation of the accumulation of human knowledge. This paper does three central things. First, drawing from recent work in epistemology, a rival account of cognitive enhancement, framed in terms of the notion of cognitive achievement rather than knowledge, is proposed. Second, we outline and respond to an axiological objection to our proposal that draws (...) from recent work by Leon Kass (2004), Michael Sandel (2009), and John Harris (2011) to the effect that ‘enhanced’ cognitive achievements are (by effectively removing obstacles to success) not worthy of pursuit, or are otherwise ‘trivial’. Third, we show how the cognitive achievement account of cognitive enhancement proposed here fits snugly with recent active externalist approaches (e.g., extended cognition) in the philosophy of mind and cognitive science.

Bernard Lonergan has argued for a theory of cognition that is transcendentally secure, that is, one such that any plausible attempt to refute it must presuppose its correctness, and one that also grounds a correct metaphysics and ontology. His proposal combines an identity theory of knowledge with an intentional relation between knower and known. It depends in a crucial way upon an appropriation of one’s own cognitional motives and acts, that is, upon “knowing one’s own knowing.” I argue that because (...) of conflicts between the identity and intentionality components of the theory, rational self-appropriation cannot, as Lonergan claims, be an iteration of just the same acts by which we acquire other sorts of knowledge. I propose an amended theory in which the relation between intending-subject and intended-object of first-level cognition becomes, in RSA, a numerical identity of knower and known and of the epistemic and the ontological.

This note calls attention to the fact that efficient causes – the sort of cause that changes something or makes something happen – can play no constitutive role in the immediate, cognitively conscious relation between cognitive subject and a cognit-ive object. It notes that: (1) it is a necessary condition for an efficient causal relation that it alter its relata; and (2) it is a necessary condition for a conscious cognitive relat-ion that it does not alter its relata. This has (...) important implication for the theories of knowledge and consciousness, the “Hard Problem,” and related puzzles. (shrink)

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of rational action, and rational (...) decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

Opponents of genetic enhancement technologies often argue that the pursuit of these technologies will lead to self-defeating collective outcomes, massive social inequalities, or other forms of collective harm. They assume that these harms will outweigh individual benefits. Defenders of genetic enhancement technologies counter that individual benefits will outweigh collective harms and there will be no conflict between individual and collective interests. The present contribution tries to advance the debate by providing a more detailed discussion of the conditions under which individual (...) and collective interests may conflict.It presents a simple model that clarifies the conditions in which the use of genetic enhancement technologies may lead to self-defeating collective outcomes and social inequalities. It argues that given current inequalities, these conditions might indeed obtain as new genetic knowledge leads to a transition in population health. If they do, then genetic enhancement will steepen the social gradient in health. Thus, regulating access to enhancement technologies should be a matter of social justice. (shrink)

In the early years of the eighteenth century Leibniz had several interactions with John Toland. These included, from 1702 to 1704, discussions of materialism. Those discussions culminated with the consideration of Toland's 1704 Letters to Serena, where Toland argued that matter is necessarily active. In this paper I argue for two main theses about this exchange and its consequences for our wider understanding. The first is that, despite many claims that Toland was at the time of Letters to Serena a (...) Spinozist, we can make better sense of him as a sort of Hobbesian materialist. The second main point concerns reasons for materialism, and in particular a story Locke tells in the Essay about materialists' motives. Toland defends his materialism by arguing that matter is active, and argues that matter is active by using a conceivability argument. But this is not the crude conceivability argument that Locke suggests motivates materialists. This (together with reflecting on some of Hobbes's arguments) suggests that we might well tell a Lockean story about reasons for early modern materialism, but not Locke's story. (shrink)

Louis Charland has argued that the Cluster B personality disorders, including borderline personality disorder, are primarily moral rather than clinical conditions. Part of his argument stems from reflections on effective treatment of borderline personality disorder. In the argument from treatment, he claims that successful treatment of all Cluster B personality disorders requires a positive change in a patient’s moral character. Based on this claim, he concludes (1) that these disorders are, at root, deficits in moral character, and (2) that effective (...) treatment of these disorders requires a sort of moral education rather than clinical intervention. In this paper, I evaluate the argument from treatment through a critical analysis of two psychotherapeutic interventions that have shown recent effectiveness against borderline personality disorder. I suggest that both Dialectical Behaviour Therapy and Mentalization-Based Treatment indicate that borderline personality disorder is, at root, a deficit in non-moral cognitive and emotional capacities. I suggest that these non-moral deficits obscure the expression of an otherwise intact moral character. In light of this, I conclude that effective treatment of borderline personality disorder requires primarily clinical intervention rather than moral edification. (shrink)

The notion of signification is an important part of Hobbes's philosophy of language. It also has broader relevance, as Hobbes argues that key terms used by his opponents are insignificant. However Hobbes's talk about names' signification is puzzling, as he appears to have advocated conflicting views. This paper argues that Hobbes endorsed two different views of names' signification in two different contexts. When stating his theoretical views about signification, Hobbes claimed that names signify ideas. Elsewhere he talked as if words (...) signified the things they named. Seeing this does not just resolve a puzzle about Hobbes's statements about signification. It also helps us to understand how Hobbes's arguments about insignificant speech work. With one important exception, they depend on the view that names signify things, not on Hobbes's stated theory that words signify ideas. The paper concludes by discussing whether arguments about insignificant speech can provide independent support for Hobbes's views about other issues, such as materialism. (shrink)

Leibniz frequently uses the notion of expression, but it is not easy to see just how he understood that relation. This paper focuses on the particular case of the expression of God, which is prominent in the 'Discourse on Metaphysics'. The treatment of expression there suggests several questions. Which substances did Leibniz believe expressed God? Why did Leibniz believe those substances expressed God? And did he believe that all substances expressed God in the same way and for the same reasons? (...) In answering those questions the paper distinguishes two views about expression in the 'Discourse', considers Leibniz's reasons for holding that substances express their causes, and argues that Leibniz's views about emanative causation are important for understanding the unity of his apparently distinct views here. The paper concludes by looking briefly at how the 'Discourse' fits into the evolution of Leibniz's views on this issue over time. (shrink)

This chapter conceptually analyzes the post-traumatic stress injuries called moral injury, moral fatigue or exhaustion, and broken spirit. It then identifies two puzzles. First, soldiers sometimes sustain moral injury even from doing right actions. Second, they experience moral exhaustion from making decisions even where the morally right choice is so obvious that it shouldn’t be stressful to make it; and even where rightness of decision is so murky that no decision could be morally faulted. The injuries result of mistaken moral (...) self-evaluation. Methods of preventing and treating these injuries are defended, including training in self-forgiveness, moral off-loading of actions and decisions to persons and devices less likely to feel inappropriate guilt, and the use of drugs to prevent such guilt. The foregoing has been about moral injury erroneously resulting from the non-violation of a correct moral code. But the chapter then introduces the concept of moral pseudo-injury—felt moral injury that has in reality resulted from violation of a false moral code, so that no one has really been morally injured. This can be used as a method in warfighting. And since the injuries it produces are illusory, this would be morally superior to physical violence. For it causes less injury to its victims, and should cause less guilt in those who must inflict it. Historical precedents are considered. Finally, our enemies often use moral pseudo-injury against us, in the form of terrorist violence against civilians. Terrorism causes comparatively few harms, yet we mistakenly see it as more morally horrific than conventional combat that causes much worse loss of life among armed forces members. Here we need the nuancing and clarifying power of philosophy to restore a sense of proportion, thence to prevent or therapize the moral pseudo-injury we may experience from these sorts of attacks. (This is a pre-penultimate version of the published version, available from OUP at the external link, which contains minor variances. The paper was earlier known as "PTSD Weaponized: A Theory of Moral Injury"; that now superseded version is archived under "past conferences" on the Center for Ethics and the Rule of Law website.).
