Brian Cutter objected to the consequence argument due to its dependence on the principle that miracle workers are metaphysically impossible. A miracle worker is someone who has the ability to act in a way such that the laws of nature would be violated. While there is something to the thought that agents like us do not have this ability, Cutter claims that there is no compelling reason to regard miracle workers as metaphysically impossible. However, the paper contends that miracle (...) workers are indeed impossible according to well-known theories concerning the laws of nature. This result highlights the reliance of the consequence argument on a plausible premise, which is widely accepted by proponents of non-Humean views of laws. The paper also provides a way to explain away the intuition that miracle workers are possible, but this has the upshot that a recent, two-dimensional formulation of the consequence argument is unsound.

Reasoning over our knowledge bases and theories often requires non-deductive inferences, especially – but by no means only – when commonsense reasoning is the case, i.e. when practical agency is called for. This kind of reasoning can be adequately formalized via the notion of supraclassical consequence, a non-deductive consequence tightly associated with default and non-monotonic reasoning and featuring centrally in abductive, inductive, and probabilistic logical systems. In this paper, we analyze core concepts and problems of these systems in (...) the light of supraclassical consequence. (shrink)

It is widely accepted among medical ethicists that competence is a necessary condition for informed consent. In this view, if a patient is incompetent to make a particular treatment decision, the decision must be based on an advance directive or made by a substitute decision-maker on behalf of the patient. We call this the competence model. According to a recent report of the United Nations (UN) High Commissioner for Human Rights, article 12 of the UN Convention on the Rights of (...) Persons with Disabilities (CRPD) presents a wholesale rejection of the competence model. The High Commissioner here adopts the interpretation of article 12 proposed by the Committee on the Rights of Persons with Disabilities. On this interpretation, CRPD article 12 renders it impermissible to deny persons with mental disabilities the right to make treatment decisions on the basis of impaired decision-making capacity and demands the replacement of all regimes of substitute decision-making by supported decision-making. In this paper, we explicate six adverse consequences of CRPD article 12 for persons with mental disabilities and propose an alternative way forward. The proposed model combines the strengths of the competence model and supported decision-making. (shrink)

We tend to think that philosophical progress, to the extent that it exists, is a good thing. I agree. Even so, it has some surprising unfortunate consequences for the rationality of philosophical belief.

ABSTRACT: This 1974 paper builds on our 1969 paper (Corcoran-Weaver [2]). Here we present three (modal, sentential) logics which may be thought of as partial systematizations of the semantic and deductive properties of a sentence operator which expresses certain kinds of necessity. The logical truths [sc. tautologies] of these three logics coincide with one another and with those of standard formalizations of Lewis's S5. These logics, when regarded as logistic systems (cf. Corcoran [1], p. 154), are seen to be equivalent; (...) but, when regarded as consequence systems (ibid., p. 157), one diverges from the others in a fashion which suggests that two standard measures of semantic complexity may not be as closely linked as previously thought. -/- This 1974 paper uses the linear notation for natural deduction presented in [2]: each two-dimensional deduction is represented by a unique one-dimensional string of characters. Thus obviating need for two-dimensional trees, tableaux, lists, and the like—thereby facilitating electronic communication of natural deductions. The 1969 paper presents a (modal, sentential) logic which may be thought of as a partial systematization of the semantic and deductive properties of a sentence operator which expresses certain kinds of necessity. The logical truths [sc. tautologies] of this logic coincides those of standard formalizations of Lewis’s S4. Among the paper's innovations is its treatment of modal logic in the setting of natural deduction systems--as opposed to axiomatic systems. The author’s apologize for the now obsolete terminology. For example, these papers speak of “a proof of a sentence from a set of premises” where today “a deduction of a sentence from a set of premises” would be preferable. 1. Corcoran, John. 1969.

This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

Incompatibilism about responsibility and determinism is sometimes directly construed as the thesis that if we found out that determinism is true, we would have to give up the reactive attitudes. Call this "the consequence". I argue that this is a mistake: the strict modal thesis does not entail the consequence. First, some incompatibilists (who are also libertarians) may be what we might call *resolute responsibility theorists* (or "flip-floppers"). On this view, if we found out that determinism is true, (...) this would not be to find out that no one is responsible; instead, what this would suggest is that incompatibilism is after all false. Second, some incompatibilists may instead deny the claim that if we found out that no one deserves the reactiveattitudes, we would have to give up the reactive attitudes. Call this position *innocent incompatibilism*. I explore several different reasons why the fact that no one deserves the reactive attitudes likely does not translate into a requirement for us to give up the reactive attitudes. The upshot: incompatibilism may be practically irrelevant, even if true. (shrink)

Environmental activism is expected to improve society’s well-being and environmental sustainability. Nevertheless, some inappropriate ways of activism, like road blockage, art vandalism, assaults, etc., have been recently conducted and risked causing adverse repercussions, including violence escalation. The current study aims to explore which types of environmental activism are more likely to escalate violence between activists, affected citizens, and police. Bayesian Mindsponge Framework (BMF) analytics was employed to analyze a dataset of 89 blockage, vandalism, and harassment cases in 13 countries in (...) this exploratory study. We discovered that rallies and demonstrations, marches, event disruption, and art vandalism were less likely to escalate violence between protestors, other citizens, and the police. In contrast, road blockades and assaults are more likely to lead to violence escalation. Apart from those, sabotage was found to have an ambiguous relationship with the violence escalation. Based on these results, we suggest that climate activists should be more selective in adopting activism approaches to raise public awareness and support and avoid using tactics that might be counterproductive and reduce public backing, such as road blockage and assaults. Despite the negative impact of art vandalism on violence escalation, we also discussed why art vandalism should not be used since it can curb the effectiveness of artivism, showing misuse of artworks (e.g., paintings, music, films) for environmental activism.

What is the connection between valid inference and true conditionals? Many conditional logics require that when A is a logical consequence of B, "if B then A" is true. Taking counterlogical conditionals seriously leads to systems that permit counterexamples to that general rule. However, this leaves those of us who endorse non-trivial accounts of counterpossible conditionals to explain what the connection between conditionals and consequence is. The explanation of the connection also answers a common line of objection to (...) non-trivial counterpossibles, which is based on a transition from valid arguments to the corresponding conditionals. It also contributes to the wider project of illuminating the connections between contexts of utterance, on the one hand, and the truth-conditions of conditionals uttered in those contexts, on the other.

Consequence rleations over sets of "judgments" are defined by using "overdetermined" as well as "underdetermined" valuations. Some of these relations are shown to be categorical. And generalized soundness and completeness results are given for both multiple and single conclusion consequence relations.

Contrastivists view ought-sentences as expressing comparisons among alternatives. Deontic actualists believe that the value of each alternative in such a comparison is determined by what would actually happen if that alternative were to be the case. One of the arguments that motivates actualism is a challenge to the principle of agglomeration over conjunction—the principle according to which if you ought to run and you ought to jump, then you ought to run and jump. I argue that there is no way (...) of developing the actualist insight into a logic that invalidates the agglomeration principle without also invalidating other desirable patterns of inference. After doing this, I extend the analysis to other contrastive views that challenge agglomeration in the way that the actualist does. This motivates skepticism about the actualist’s way of challenging agglomeration. (shrink)

2nd edition. The theory of logical consequence is central in modern logic and its applications. However, it is mostly dispersed in an abundance of often difficultly accessible papers, and rarely treated with applications in mind. This book collects the most fundamental aspects of this theory and offers the reader the basics of its applications in computer science, artificial intelligence, and cognitive science, to name but the most important fields where this notion finds its many applications.

The aim of this article is to outline a pragmatist image of science following Rorty’s discussions and critics of epistemology and to develop some consequences of it in the philosophical analysis and its relations to culture. I will deal with some aspects of how scientific practice is construed and understood, and also outline the shift in Philosophy of Science from epistemological to ethical-political concerns that are implied in his proposal. I will contend that this perspective suggests an interesting way of (...) analysing scientific practices, theories, and public policies of it. Furthermore, I will suggest that it successfully connects the most interesting proposals of contemporary scientific views in philosophy. Finally, I will use some examples in physics and biology to illustrate my assertions. (shrink)

The Consequence Argument has elicited various responses, ranging from acceptance as obviously right to rejection as obviously problematic in one way or another. Here we wish to focus on one specific response, according to which the Consequence Argument begs the question. This is a serious accusation that has not yet been adequately rebutted, and we aim to remedy that in what follows. We begin by giving a formulation of the Consequence Argument. We also offer some tentative proposals (...) about the nature of begging the question. Although the charge of begging the question is frequently made in philosophy, it is surprisingly difficult to pin down the precise nature of this dialectical infelicity (or family of such infelicities). Thus we offer some new proposals about the nature of begging the question with an eye to understanding what is going on in central cases in which the charge is legitimately made. We then defend the Consequence Argument against the charge that it begs the question, so construed. We contend that, whatever the other liabilities of the argument may be, it does not beg the question against the compatibilist. (shrink)

Since at least the 1960s, deontic logicians and ethicists have worried about whether there can be normative systems that allow conflicting obligations. Surprisingly, however, little direct attention has been paid to questions about how we may reason with conflicting obligations. In this paper, I present a problem for making sense of reasoning with conflicting obligations and argue that no deontic logic can solve this problem. I then develop an account of reasoning based on the popular idea in ethics that reasons (...) explain obligations and show that it solves this problem. (shrink)

We defend three controversial claims about preference, credence, and choice. First, all agents (not just rational ones) have complete preferences. Second, all agents (again, not just rational ones) have real-valued credences in every proposition in which they are confident to any degree. Third, there is almost always some unique thing we ought to do, want, or believe.

Conditional excluded middle (CEM) is the following principe of counterfactual logic: either, if it were the case that φ, it would be the case that ψ, or, if it were the case that φ, it would be the case that not-ψ. I will first show that CEM entails the identity of indiscernibles, the falsity of physicalism, and the failure of the modal to supervene on the categorical and of the vague to supervene on the precise. I will then argue that (...) we should accept these startling conclusions, since CEM is valid. (shrink)

In “Bayesianism, Infinite Decisions, and Binding”, Arntzenius et al. (Mind 113:251–283, 2004 ) present cases in which agents who cannot bind themselves are driven by standard decision theory to choose sequences of actions with disastrous consequences. They defend standard decision theory by arguing that if a decision rule leads agents to disaster only when they cannot bind themselves, this should not be taken to be a mark against the decision rule. I show that this claim has surprising implications for a (...) number of other debates in decision theory. I then assess the plausibility of this claim, and suggest that it should be rejected.

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

Decisions in medical contexts have immediate and obvious consequences in terms of health and sometimes death or survival. Medical decisions also have less obvious and less immediate consequences, including effects on the long-term physical and mental well-being of patients, their families and of care-givers, as well as on the distribution of scarce medical resources. Some of these consequences are hard to measure and estimate. Even harder, perhaps, is the determination of the relative value of different consequences. How should consequences be (...) evaluated? How do uncertainties and biases affect our evaluations of consequences? What influence should our evaluations of consequences have on our actions? These questions are all philosophical in nature.

This paper aims to contribute a design-focused perspective on the ‘alternative paradigm research’ discussion. To clarify the aspect of ‘design-focus’ that we wish to refer to, we will use the term ‘areas of design practice’ to cover those activities that focus on the conception and production of artefacts, in contrast to the activities of theorizing and writing histories. The literature on academic research in areas of design practice encompasses a board range of subjects and terminology -- it refers to the (...) creative and performing arts, the arts, design, etc., however what we take to be common in the literature is an interest in research involving the creation of original artefacts. In this paper, we cluster together the currently academicized, previously vocational areas. -/- We claim that researchers in different disciplines operate in different research paradigms owing to different worldviews. A worldview is determined by a set of foundational beliefs that are taken on faith, and a research paradigm is defined by axioms and assumptions that are a consequence of that worldview. For example, the scientific view of the world is that it exists independently from the individual and the individual’s thoughts about it; and it is possible to find out objective facts about the world by following certain procedures. This worldview conditions a research paradigm with an ontology of a real external world; that methodologically the data that is collected in procedurally appropriate ways will yield objective facts about that world; and that epistemologically the researcher stands in a disengaged relation to the world that is being investigated. The procedures that are regarded as appropriate within a particular research paradigm form the research models that are acceptable in that paradigm, and these research models determine what one should do in order to extend knowledge in a particular subject. Of course, the scientific worldview is not the only one, and this paper will contrast it to the design worldview as indicating the emergence of a unique research paradigm. -/- The relationship between a community’s worldview and the academic models that it adopts may be functional or dysfunctional. We claim that the relationship in the areas of design practice is often dysfunctional. This is because the academic model has not developed authentically in relation to its fundamental beliefs, but has done so in response to external forces for academicization. When pushed into the academy, areas of design practice did not possess their own academic models that were effectively linked to its worldview. We claim that, as a result, these areas simply co-opted research models from other disciplines. -/- The paper proposes a rationalistic approach for investigating the relationship between worldview and research paradigm -- between fundamental beliefs, theoretical concepts and methodology in research models. The rationalistic approach enables a critique, which reveals that there are indeed problematic issues with adopting academic models from other research paradigms in an uncritical way, and concludes that areas of design practice should be investigated as an example of a distinct worldview.

Drawing on a passage from Ramsey's Truth and Probability, we formulate a simple, plausible constraint on evaluating the accuracy of credences: the Calibration Test. We show that any additive, continuous accuracy measure that passes the Calibration Test will be strictly proper. Strictly proper accuracy measures are known to support the touchstone results of accuracy-first epistemology, for example vindications of probabilism and conditionalization. We show that our use of Calibration is an improvement on previous such appeals by showing how it answers (...) or sidesteps problems that have been raised for previous work in this area. (shrink)

This chapter examines a common objection to sex robots: the symbolic-consequences argument. According to this argument sex robots are problematic because they symbolise something disturbing about our attitude to sex-related norms such as consent and the status of our sex partners, and because of the potential consequences of this symbolism. After formalising this objection and considering several real-world uses of it, the chapter subjects it to critical scrutiny. It argues that while there are grounds for thinking that sex robots could (...) symbolically represent a troubling attitude toward women (and maybe children) and the norms of interpersonal sexual relationships, the troubling symbolism is going to be removable in many instances and reformable in others. What will ultimately matter are the consequences of the symbolism but these consequences are likely to be difficult to ascertain. This may warrant an explicitly experimental approach to the development of this technology. (shrink)

As a moral foundation for vegetarianism and other consumer choices, act consequentialism can be appealing. When we justify our consumer and dietary choices this way, however, we face the problem that our individual actions rarely actually precipitate more just agricultural and economic practices. This threshold or individual impotence problem engaged by consequentialist vegetarians and their critics extends to morally motivated consumer decision-making more generally, anywhere a lag persists between individual moral actions taken and systemic moral progress made. Regan and others (...) press just this point against Singer's utilitarian basis for vegetarianism; recently Chartier criticizes act-consequentialist vegetarianism by identifying many factors weakening the connection between individual meat purchases and changes in animal production. While such factors are relevant to act-consequentialist moral reasoning, I argue, they need not defeat the act-consequentialist case for vegetarianism and consumer ethics. This is shown by offering a probabilistic account of the threshold issue and discussing the positive and negative role-modelling effects of our morally motivated dietary and consumer choices.

This special issue collects together nine new essays on logical consequence :the relation obtaining between the premises and the conclusion of a logically valid argument. The present paper is a partial, and opinionated,introduction to the contemporary debate on the topic. We focus on two influential accounts of consequence, the model-theoretic and the proof-theoretic, and on the seeming platitude that valid arguments necessarilypreserve truth. We briefly discuss the main objections these accounts face, as well as Hartry Field’s contention that (...) such objections show consequenceto be a primitive, indefinable notion, and that we must reject the claim that valid arguments necessarily preserve truth. We suggest that the accountsin question have the resources to meet the objections standardly thought to herald their demise and make two main claims: (i) that consequence, as opposed to logical consequence, is the epistemologically significant relation philosophers should be mainly interested in; and (ii) that consequence is a paradoxical notion if truth is.

Alex Worsnip argues in favor of what he describes as a particularly robust version of fallibilism: subjects can sometimes know things that are, for them, possibly false (in the epistemic sense of 'possible'). My aim in this paper is to show that Worsnip’s argument is inconclusive for a surprising reason: the existence of possibly false knowledge turns on how we ought to model entailment or consequence relations among sentences in natural language. Since it is an open question how we (...) ought to think about consequence in natural language, it is an open question whether there is possibly false knowledge. I close with some reflections on the relation between possibly false knowledge and fallibilism. I argue that there is no straightforward way to use linguistic data about natural language epistemic modals to either verify or refute the fallibilist thesis. (shrink)

In ‘Measuring the Consequences of Rules’, Holly Smith presents two problems involving the indeterminacy of compliance, which she takes to be fatal for all forms of rule-utilitarianism. In this reply, I attempt to dispel both problems.

The consequence argument is a powerful incompatibilist argument for the conclusion that, if determinism is true, what one does is what one must do. A major point of controversy between classical compatibilists and incompatibilists has been over the use of ‘can’ in the consequence argument. Classical compatibilists, holding that abilities to act are dispositions, have argued that ‘can’ should be analyzed as a conditional. But such an analysis of ‘can’ puts compatibilists in a position to grant the premises (...) of the argument while denying the conclusion. Incompatibilists remain unconvinced, and this corner of the debate over free will has reached a dialectical impasse. The present paper has two aims. First, to offer a new dialectical point of entry into this dispute on behalf of incompatibilists. By making use of Angelika Kratzer's influential semantic work on ‘can’ and ‘must’, I argue that incompatibilists are in a position to offer a plausible, positive treatment of ‘can’ that favors their view. Second, even if one does not think incompatibilism is thereby true (for as we shall see there are places to push back), the Kratzer semantics yields a number of important insights concerning the consequence argument that should be of broad interest.

Are there virtues that constitutively involve using certain concepts? Does it make sense to speak of rights or duties to use certain concepts? And do consequentialist approaches to concepts necessarily have to reproduce the difficulties that plague utilitarianism? These are fundamental orientating questions for the emerging field of conceptual ethics, which invites us to reflect critically about which concepts to use. In this article, I map out and explore the ways in which conceptual ethics might take its cue from virtue-ethical, (...) deontological, and consequentialist traditions of ethical thought, flagging the main difficulties facing each approach. I end by sketching how the various dimensions of evaluation singled out by these three traditions might be combined in a single approach. (shrink)

The theme of this paper is Husserl’s concept of experience, through which I hope to show that and how Husserl’s description points the way toward a more adequate account of experience than traditional ones operating within realist-idealist and rationalist-empiricist frameworks.

The consequence argument of van Inwagen is widely regarded as the best argument for incompatibilism. Lewis’s response is praised by van Inwagen as the best compatibilist’s strategy but Lewis himself acknowledges that his strategy resembles that of Lehrer. A comparison will show that one can speak about Lehrer-Lewis strategy, although I think that Lewis’s variation is dialectically slightly stronger. The paper provides a response to some standard objections of incompatibilists to the Lehrer-Lewis reply.

This paper provides an analysis of the way in which two foundational principles of medical ethics–the trusted doctor and patient autonomy–can be undermined by the use of machine learning (ML) algorithms and addresses its legal significance. This paper can be a guide to both health care providers and other stakeholders about how to anticipate and in some cases mitigate ethical conflicts caused by the use of ML in healthcare. It can also be read as a road map as to what (...) needs to be done to achieve an acceptable level of explainability in an ML algorithm when it is used in a healthcare context. (shrink)

Philosophers sometimes give arguments that presuppose the following principle: two theories can fail to be empirically equivalent on the sole basis that they present different “thick” metaphysical pictures of the world. Recently, a version of this principle has been invoked to respond to the argument that composite objects are dispensable to our best scientific theories. This response claims that our empirical evidence distinguishes between ordinary and composite-free theories, and it empirically favors the ordinary ones. In this paper, I ask whether (...) this response to the dispensability argument is tenable. I claim that it is not. This is because it presupposes an indefensible thesis about when two empirical consequences are distinct or the same. My argument provides some insight into what our empirical consequences are, and I conclude that empirical evidence is radically metaphysically neutral. This gives us some insight into the significant content of our scientific theories—the content that a scientific realist is committed to—and I show how this insight relates to questions about theoretical equivalence more broadly.

In this essay, I argue that neurophysiological materialism - the thesis that all of our mental contents are caused by non-mental, purely physical brain states - is epistemically self-refuting, and ought to be rejected even if it cannot be otherwise disproved.

This dissertation aimed to examine the consequence of health-induced poverty and two policy responses to address this issue among older adults in the United States and China. Specifically, Paper I investigates whether public transfers crowded out private transfers among rural and urban Chinese older families and if this dynamic would change when health care expenses were high. Paper II examines the effect of New Rural Cooperative Medical Insurance, a national health insurance program for rural residents in China, on changing (...) the incidence of health-induced poverty among middle-aged and older beneficiaries. Paper III tests the effects of closing the Medicare Part D donut hole (coverage gap) through the Affordable Care Act (ACA) on changing prescription drug cost-induced poverty. Overall, the findings obtained from these three papers provide empirical evidence that health-induced poverty is prevalent among older adults in both China and the United States and the current public transfers and health policies are either ineffective or insufficient to reduce health-induced poverty as intended.

In this case discussion, Barnhill and Devine collect and present a significant amount of recent research on the various reasons why people struggle to succeed in weight loss programmes. Specifically, the authors focus on what they call ‘behavioural weight loss interventions’, which are ‘research, clinical or public health efforts to promote individual healthy eating and physical activity behaviours’. As defined, this is a very broad category of interventions and presumably includes all kinds of dieting and weight loss programmes or promotion (...) efforts short of private or independently chosen programmes. The authors argue, in a nutshell, that these clinical, research, and public health interventions have low efficacy, and while they may have some health or other benefits, the balance of evidence presented shows that they harm people in multiple ways.

In this contribution an attempt is made to analyze an important mathematical discovery, the theorem of Gödel, and to explore the possible impact on the consistency of metaphysical systems. It is shown that mathematics is a pointer to a reality that is not exclusively subjected to physical laws. As the Gödel theorem deals with pure mathematics, the philosopher as such can not decide on the rightness of this theorem. What he, instead can do, is evaluating the general acceptance of this (...) mathematical finding and reflect on the consistency between consequences of the mathematical theorem with consequences of his metaphysical view. The findings of three mathematicians are involved in the argumentation: first Gödel himself, then the further elaboration by Turing and finally the consequences for the human mind as worked out by Penrose. As a result one is encouraged to distinguish two different types of intellectual activity in mathematics, which both can be carried out by humans. The astonishing thing is not the distinction between a formalized, logic approach on the one side and intuition, mathematical insight and meaning on the other. Philosophically challenging, however, is the claim that principally only one of these intellectual activities can be carried out by objects exclusively bound to the laws of physical reality.

The importance of addressing the existential threat to humanity, climate change, has grown remarkedly in recent years while conflicting views and interests in societies exist. Therefore, climate change agendas have been weaponized to varying degrees, ranging from the international level between countries to the domestic level among political parties. In such contexts, climate change agendas are predominantly driven by political or economic ambitions, sometimes unconnected to concerns for environmental sustainability. Consequently, it can result in an environment that fosters antagonism and (...) disputes over power and position and increases the risk of prolonged confrontations, hindering the collective global efforts to mitigate and adapt to climate change. Through the current discourse, we aim to provide a preliminary definition of the weaponization of climate change and environmental degradation and examine its risks and consequences on international relations, political dynamics, public perception, and the comprehensive integrity of climate action. We also recommend embracing a globally coordinated, scientifically substantiated approach to circumvent climate change by building an eco-surplus cultural value system. (shrink)

This chapter has three aims. Firstly, it elaborates the so-called pragmatic approach to fictionalism. By evoking some classical pragmatic theories of fictive utterances, it gives an account of pragmatic properties responsible for the difference between serious and fictive utterances. The authors argue for the thesis that the pragmatic approach can be applied plausibly to all kinds of fictionalism, that is from instrumentalism to figuralism. Secondly, the authors investigate some consequences of the suggested account for fictionalist theories in general. They show (...) that some more or less known difficulties of fictionalist theories become more serious if one accepts the pragmatic approach. The chapter discusses two of them, namely the problem of entirely fictional discourses and the apparent contradiction between hermeneutic fictionalism and first person authority. Thirdly, the authors investigate the consequences of the pragmatic approach for mental fictionalism in particular. At the end of the paper, they argue that once the pragmatic approach is applied to mental fictionalism, the well-known problem of cognitive suicide becomes especially nagging. They suggest it is highly questionable that mental fictionalism is worth to endorse in the light of these serious difficulties. (shrink)

The “sign of consequence” is a notation for propositional logic that Peirce invented in 1886 and used at least until 1894. It substituted the “copula of inclusion” which he had been using since 1870.

If an argument is valid, it is impossible for its premises to be true, and its conclusion false. But how should we understand these notions of truth and impossibility? Here, I present the answers given by John Buridan (ca. 1300-60), showing (i) how he understands truth in his anti-realist metaphysics, and (ii) how he understands modality in connection with causal powers. In short: if an argument exists and is valid, there does not exist a power capable of making the premises (...) true and, at the same time, making the conclusion false. (shrink)

Recent work in the truthmakers literature demonstrates that the logic of truthmaking is distinct from classical logic. Since free will is an ontological issue, and not merely a semantic issue, arguments about free will ought to be sensitive to these developments. In Truthmakers and the Direct Argument, Hermes argues that one of the main arguments for incompatibiilsm fails precisely where the truthmakers literature would predict. Here, I argue that similar problems make the Consequence Argument untenable.

Substructural logics and their application to logical and semantic paradoxes have been extensively studied, but non-reflexive systems have been somewhat neglected. Here, we aim to fill this lacuna, at least in part, by presenting a non-reflexive logic and theory of naive consequence (and truth). We also investigate the semantics and the proof-theory of the system. Finally, we develop a compositional theory of truth (and consequence) in our non-reflexive framework.

This elementary 4-page paper is a preliminary survey of some of the most important uses of ‘condition’ and ‘consequence’ in American Philosophy. A more comprehensive treatment is being written. Your suggestions, questions, and objections are welcome. A statement of a conditional need not be a conditional statement and conditional statement need not be a statement of a conditional.
