Realists about possible worlds typically identify possible worlds with abstract objects, such as propositions or properties. However, they face a significant objection due to Lewis (1986), to the effect that there is no way to explain how possible worlds-as-abstract objects represent possibilities. In this paper, I describe a response to this objection on behalf of realists. The response is to identify possible worlds with propositions, but to deny that propositions are abstract objects, or indeed objects at all. Instead, I argue (...) that realists should follow Prior (1971) and others in treating higher-order quantification (e.g. quantification into predicate or sentence position) as a genuine form of quantification in its own right, and so in particular, not to be analysed in terms of first-order quantification over abstract objects. I argue that from this ‘higher-orderist’ perspective, there is a relatively straightforward answer to the question of how possible worlds-as-propositions succeed in representing possibilities.

What is commonly referred to as the Adoption Problem is a challenge to the idea that the principles of logic can be rationally revised. The argument is based on a reconstruction of unpublished work by Saul Kripke. As the reconstruction has it, Kripke extends the scope of Willard van Orman Quine's regress argument against conventionalism to the possibility of adopting new logical principles. In this paper we want to discuss the scope of this challenge. Are all revisions of logic subject (...) to the Adoption Problem? If not, are there significant cases of logical revision that are subject to the Adoption Problem? We will argue that both questions should be answered negatively. (shrink)

Wie ist es wohl, eine Fledermaus zu sein? Wäre ein rein physikalisches Duplikat von mir nur ein empfindungsloser Zombie? Muss man sich seinem Schicksal ergeben, wenn man sich unfreiwillig als lebensnotwendige Blutwaschanlage eines weltberühmten Violinisten wieder findet? Kann man sich wünschen, der König von China zu sein? Bin ich vielleicht nur ein Gehirn in einem Tank mit Nährflüssigkeit, das die Welt von einer Computersimulation vorgegaukelt bekommt? Worauf beziehen sich die Menschen auf der Zwillingserde mit ihrem Wort 'Wasser', wenn es bei (...) ihnen gar kein H2O gibt? -/- Diese und weitere seltsame Fragen sind das tägliche Brot vieler professioneller Philosophen. Die abstrusen Umstände, die dabei geschildert werden, nennt man "Gedankenexperimente". -/- Was soll die Erörterung dieser Szenarien, die sich so weit von unserem alltäglichen Leben, z.T. außerhalb der Grenzen unserer Wirklichkeit abspielen? Welche Rolle spielen diese "Gedankenexperimente" in der philosophischen Methodologie? Ist diese Rolle überhaupt berechtigt? -/- Das vorliegende Buch gibt Antworten auf diese Fragen. Es stellt sich heraus, dass diese seltsamen Gedankenexperimente nicht nur berechtigte, sondern überaus wichtige Instrumente philosophischen Forschens darstellen. (shrink)

We should not be creating conscious, humanoid agents but an entirely new sort of entity, rather like oracles, with no conscience, no fear of death, no distracting loves and hates.

Say that the Moving Spotlight Theory (MST) combines the following three theses: A-THEORY : There is an absolute distinction between present and non-present time.

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

Berkeley argues that claims about divine predication (e.g., God is wise or exists) should be understood literally rather than analogically, because like all spirits (i.e., causes), God is intelligible only in terms of the extent of his effects. By focusing on the harmony and order of nature, Berkeley thus unites his view of God with his doctrines of mind, force, grace, and power, and avoids challenges to religious claims that are raised by appeals to analogy. The essay concludes by showing (...) how a letter, supposedly by Berkeley, to Peter Browne ("discovered" in 1969 by Berman and Pittion) is, in fact, by John Jackson (1686-1763), controversial theologian and friend of Samuel Clarke.

According to many accounts of faith—where faith is thought of as something psychological, e.g., an attitude, state, or trait—one cannot have faith without belief of the relevant propositions. According to other accounts of faith, one can have faith without belief of the relevant propositions. Call the first sort of account doxasticism since it insists that faith requires belief; call the second nondoxasticism since it allows faith without belief. The New Testament may seem to favor doxasticism over nondoxasticism. For it may (...) seem that, according to the NT authors, one can have faith in God, as providential, or faith that Jesus is the Messiah, or be a person of Christian faith, and the like only if one believes the relevant propositions. In this essay, I propose to assess this tension, as it pertains to the Gospel of Mark. The upshot of my assessment is that, while it may well appear that, according to Mark, one can have faith only if one believes the relevant propositions, appearances are deceiving. Mark said no such thing. Rather, what Mark said—by way of story—about faith fits nondoxasticism at least as well as doxasticism, arguably better. More importantly, the account of faith that emerges from Mark is that faith consists in resilience in the face of challenges to living in light of the overall positive stance to the object of faith, where that stance consists in certain conative, cognitive, and behavioral-dispositional elements.

This article argues that introductory ethics classes can unwittingly create or confirm skeptical views toward morality. Introductory courses frequently include critical discussion of skeptical positions such as moral relativism and psychological egoism as a way to head off this unintended outcome. But this method of forestalling skepticism can have a residual (and unintended) skeptical effect. The problem calls for deeper pedagogical-cum-philosophical engagement with the underlying sources of skepticism. The paper provides examples of how to do this and explains the additional (...) benefits of teaching moral skepticism. (shrink)

Since nothing about God is passive, and the perception of pain is inherently passive, then it seems that God does not know what it is like to experience pain. Nor would he be able to cause us to experience pain, for his experience would then be a sensation (which would require God to have senses, which he does not). My suggestion is that Berkeley avoids this situation by describing how God knows about pain “among other things” (i.e. as something whose (...) identity is intelligible in terms of the integrated network of things). This avoids having to assume that God has ideas (including pain) apart from his willing that there be perceivers who have specific ideas that are in harmony or not in harmony with one another.

Although thought experiments were first discovered as a sui generis methodological tool by philosophers of science (most prominently by Ernst Mach), the tool can also be found – even more frequently – in contemporary philosophy. Thought experiments in philosophy and science have a lot in common. However, in this chapter we will concentrate on thought experiments in philosophy only. Their use has been the centre of attention of metaphilosophical discussion in the past decade, and this chapter will provide an overview (...) of the results this discussion has achieved and point out which issues are still open.

For Berkeley, minds are not Cartesian spiritual substances because they cannot be said to exist (even if only conceptually) abstracted from their activities. Similarly, Berkeley's notion of mind differs from Locke's in that, for Berkeley, minds are not abstract substrata in which ideas inhere. Instead, Berkeley redefines what it means for the mind to be a substance in a way consistent with the Stoic logic of 17th century Ramists on which Leibniz and Jonathan Edwards draw. This view of mind, I (...) conclude, is definitely not the bundle theory that some critics have portrayed it as being. (shrink)

When reasons are given for compositionality, the arguments usually purport to establish compositionality in an almost a priori manner. I will rehearse these arguments why one could think that compositionality is a priori true, or almost a priori true, and will find all of them inconclusive. This, in itself, is no reason against compositionality, but a reason to try to establish or defend the principle on other than quasi-a priori grounds.

What is consciousness and why is it so philosophically and scientifically puzzling? For many years philosophers approached this question assuming a standard physicalist framework on which consciousness can be explained by contemporary physics, biology, neuroscience, and cognitive science. This book is a debate between two philosophers who are united in their rejection of this kind of "standard" physicalism - but who differ sharply in what lesson to draw from this. Amy Kind defends dualism 2.0, a thoroughly modern version of dualism (...) (the theory that there are two fundamentally different kinds of things in the world: those that are physical and those that are mental) decoupled from any religious or non-scientific connotations. Daniel Stoljar defends non-standard physicalism, a kind of physicalism different from both the standard version and dualism 2.0. The book presents a cutting-edge assessment of the philosophy of consciousness and provides a glimpse at what the future study of this area might bring. (shrink)

Octavio Paz conceives of authentic philosophical reflection as ‘thinking a la intemperie’. This conception involves his idea that our contemporary historical and philosophical situation is one of intemperie espiritual. Based on the dual sense of the term intemperie for Paz, I propose that ‘thinking a la intemperie’ means: (i) Exposing our beliefs to the weathering effects of our vital, concrete experience; and (ii) apprehending reality in communion with others through poetic experience of the ever-flowing present. That is, authentic philosophical reflection (...) means making our home thinking and living without rigid, stifling ideological systems, in communion with our neighbors and with our places, here and now, in the unity of present place and present time that we create together. This mode of reflection belongs within a broad American tradition of philosophizing and, for Paz, responds to concerns compatible with those of the pragmatists. (shrink)

For Berkeley, a thing's existence 'esse' is nothing more than its being perceived 'as that thing'. It makes no sense to ask (with Samuel Johnson) about the 'esse' of the mind or the specific act of perception, for that would be like asking what it means for existence to exist. Berkeley's "existere is percipi or percipere" (NB 429) thus carefully adopts the scholastic distinction between 'esse' and 'existere' ignored by Locke and others committed to a substantialist notion of mind. Following (...) the Stoics, Berkeley proposes that, 'as' the existence of ideas, minds "subsist" rather than "exist" and, accordingly, cannot be identified as independently existing things. (shrink)

One of the most basic methods of philosophy is, and has always been, the consideration of counterfactual cases and imaginary scenarios. One purpose of doing so obviously is to test our theories against such counterfactual cases. Although this method is widespread, it is far from being commonly accepted. Especially during the last two decades it has been confronted with criticism ranging from complete dismissal to denying only its critical powers to a cautious defense of the use of thought experiments as (...) counterexamples. One of the strongest criticisms of the method of thought experimentation is "modal skepticism" as explicated and defended by Peter van Inwagen. Van Inwagen argues that the philosopher's notion of logical possibility is confused and that its epistemology is dubious. I argue that van Inwagen's skepticism is unwarranted. There is a sufficiently clear notion of logical possibility and a sufficiently straightforward way of getting to know what is logically possible. In the remainder of the paper I show how that connects with the methodology of thought experimentation in philosophy. (shrink)

There is a widespread assumption that B-theorists (according to whom there is nothing metaphysically special about the present moment in virtue of which it is present) should interpret the standard tense operators (‘it was the case that’, ‘it will be the case that’) as implicit quantifier-restrictors – so that, for example, an utterance at instant t of the sentence ‘It was the case that there are dinosaurs’ is true just in case there are dinosaurs located at some instant t* earlier (...) than t. However, it is easy to show that this interpretation of the tense operators creates serious problems for B-theorists when combined with certain other relatively uncontroversial B-theoretic assumptions. In this paper, I argue that the best way for B-theorists to respond to these problems is to treat the standard tense operators as redundant when the sentences in their scope are qualitative (i.e. not about any particular individuals).

To say that a philosophical dispute is ‘merely verbal’ seems to be an important diagnosis. If that diagnosis is correct for a particular dispute, then the right thing to do would be to declare that dispute to be over. The topic of what the disputing parties were fighting over was just a pseudo-problem (thus not really a problem), or at least – if there is a sense in which also merely verbal disputes indicate some problem, for example, insufficient clarity of (...) terminology – this problem is not substantial, or not as substantial as the disputing parties believed their problem initially to be. In this paper I will try to clarify what it means if we diagnose that two arguing parties are having a merely verbal dispute. (shrink)

Cet article se base sur des résultats d’enquête récents montrant que, chez des adolescents marocains âgés de dix à dix-huit ans, les manifestations de pensée critique dialogique se si-tuent majoritairement dans une « perspective épistémologique » appelée « relativisme » par un modèle développemental élaboré dans les quinze dernières années avec la méthode de la théorie ancrée. Pour comprendre ces résultats de recherche, qui contrastent avec ceux obte-nus auprès d’adolescents québécois et français appartenant aux mêmes groupes d’âge, nous décrivons, dans (...) un premier temps, le modèle développemental dans lequel ils prennent sens. Nous illustrons ensuite les manifestations de « perspective épistémologique relativiste » chez les adolescents marocains à l’aide d’extraits de verbatim. Les élèves ont tendance à se décen-trer de leur vécu personnel, à se représenter le point de vue d’autrui en général et à co-construire des points de vue convergents avec les pairs. Dans un deuxième temps, prenant appui sur une approche de la représentation sociale en tant que « scène », et sur la littérature touchant aux rôles des aînés dans les sociétés africaines, nous éclairons ces résultats de re-cherche par l’analyse d’une représentation sociale fréquemment mobilisée par les jeunes Ma-rocains interviewés : celle de la hiérarchie des âges et du devoir d’écoute envers les plus âgés. L’analyse de cette « scène » met en lumière des attitudes sociales inculquées aux adolescents en contexte culturel marocain, susceptibles de favoriser le développement d’une « perspective épistémologique relativiste » en matière de pensée critique dialogique.

Robert Brandom charakterisiert singuläre Termini durch ihre symmetrische substitutionsinferentielle Rolle. Er entwickelt ein transzendentales Argument, wonach solche Termini notwendig für jede Sprache sind, welche die üblichen logischen Ausdrucksressourcen wie Negation und Konditional besitzt.

Er kann auch mit der asymmetrischen inferentiellen Rolle bestimmter singulärer Termini umgehen, sofern diese nicht systematisch ist. Aber er kann der Möglichkeit nicht gerecht werden, singuläre Termini einzuführen, die nicht durch (...) eine symmetrische substitutionsinferentielle Rolle konstituiert sind. Ungeachtet der Einführung solcher Termini bleiben normale logische Ausdrucksressourcen erhalten. (shrink)

Many philosophers are very sanguine about the cognitive contributions of fiction to science and philosophy. I focus on a case study: Ichikawa and Jarvis’s account of thought experiments in terms of everyday fictional stories. As far as the contribution of fiction is not sui generis, processing fiction often will be parasitic on cognitive capacities which may replace it; as far as it is sui generis, nothing guarantees that fiction is sufficiently well-behaved to abide by the constraints of scientific and philosophical (...) discourse, not even by the minimum requirements of conceptual and logical coherence.

By focusing on the exchange between Descartes and Hobbes on how the self is related to its activities, Berkeley draws attention to how he and Hobbes explain the forensic constitution of human subjectivity and moral/political responsibility in terms of passive obedience and conscientious submission to the laws of the sovereign. Formulated as the language of nature or as pronouncements of the supreme political power, those laws identify moral obligations by locating political subjects within those networks of sensible signs. When thus (...) juxtaposed with Hobbes, Berkeley can be understood as endorsing a theologically inflected version of deontological ethics in which moral laws are linked directly to the constitution of the self.

This paper offers a novel interpretation of Descartes's conception of freedom that resolves an important tension at the heart of his view. It does so by appealing to the important but overlooked distinction between possessing a power, exercising a power, and being in a position to exercise a power.

I argue that Goodman’s philosophy should not be characterised in opposition to the philosophy of the logical empiricists, but is more fruitfully interpreted as a continuation of their philosophical programme. In particular, understanding Goodman’s philosophy as a continuation of the ideal language tradition makes explicable how a radical ontological relativist could be such a staunch nominalist at the same time.

In several essays I have argued that Berkeley maintains the same basic notion of spiritual substance throughout his life. Because that notion is not the traditional (Aristotelian, Cartesian, or Lockean) doctrine of substance, critics (e.g., John Roberts, Tom Stoneham, Talia Mae Bettcher, Margaret Atherton, Walter Ott, Marc Hight) claim that on my reading Berkeley either endorses a Humean notion of substance or has no recognizable theory of substance at all. In this essay I point out how my interpretation does not (...) assume that Berkeley adopts a bundle theory of mind, but instead redefines what it means for a simple substance to be the principle by which ideas are perceived.

In Book I of his Nicomachean Ethics (NE), Aristotle defines happiness, or eudaimonia, in accordance with an argument he makes regarding the distinctive function of human beings. In this paper, I argue that, despite this argument, there are moments in the NE where Aristotle appeals to elements of happiness that don’t follow from the function argument itself. The place of these elements in Aristotle’s account of happiness should, therefore, be a matter of perplexity. For, how can Aristotle appeal to elements (...) of happiness not entailed by his argument for what happiness involves? I will examine two instances that exemplify the sort of appeal to outside elements that I have in mind. The first deals with Aristotle’s reference, in NE, I, 8, to certain goods—ancestry, children, beauty—goods unrelated to man’s function or his fulfillment of it, but nevertheless required for his happiness. The second instance involves pleasure. Aristotle makes various arguments, both in Books I and X of the NE, that tie pleasure to the activity of the soul, and the function argument in turn. However, none of these arguments succeeds in demonstrating that pleasure would necessarily follow from this activity. Taken together then, these two examples demonstrate the extent to which Aristotle’s definition of happiness is more inclusive than his function argument permits. (shrink)

I outline Hume’s views about conceivability evidence. Then I critically scrutinize two threats to conceivability-based modal epistemology. Both arise from Hume’s criticism of claims to knowing necessary causal relationships: Firstly, a sceptical stance towards causal necessity may carry over to necessity claims in general. Secondly, since – according to a sceptical realist reading – Hume grants the eventuality of causal powers grounded in essential features of objects, conceivability-based claims to comprehensive metaphysical possibilities seem endangered. I argue that although normal conceivability-based (...) claims are defeasible, they are prima facie vindicated. (shrink)

In recent decades, environmental rights have been increasingly developed at both the national and international level, along with increased adjudication of these rights in both national (constitutional) courts and international human rights courts. These parallel trends raise a question as to whether it is better to develop and adjudicate environmental rights at the national or international level. This article considers the case made by James May and Erin Daly in favor of developing environmental rights at the national constitutional level and (...) adjudicating these rights in domestic courts. I consider the limitations of this case by showing that international environmental human rights can play a role that systematically benefits environmental protection, with adjudication in international human rights courts a key part of that process. This involves drawing on an argument offered by Allen Buchanan to justify a system of international legal human rights, which appeals to a number of benefits that such a system can provide. The argument is developed and applied to adjudication of environmental human rights in international human rights courts. First, it is shown how these benefits are realized in the area of environmental human rights. Second, it is shown how adjudication can enhance these benefits, both by providing a mechanism for their realization and by facilitating a mutually supportive relationship among them. On the basis of these enhanced benefits and the value that they add, it is concluded that there is strong justification for developing and adjudicating environmental human rights at the international level.

Although the differences between Spinoza and Nietzsche are crucial, there are several aspects on which one can trace a relevant set of similarities between the two authors. The refutation of teleology, transcendence and free will, together with the consequent embracement of fatality, the pursuit of joy, and the particular emphasis on affectivity are just a few of the resemblances that can be drawn between Spinoza and Nietzsche. This paper is focused only on the last aspect mentioned above. Both Spinoza and (...) Nietzsche developed an account of immanent pursuit of joy, which can be derived from a particular understanding of affects. The two philosophers tried to create a peculiar bridge between knowledge and affectivity, which meant a significant departure from their previous philosophical tradition, and which gave them an idiosyncratic place in the entire picture of modern thought.

Clues about what Berkeley was planning to say about mind in his now-lost second volume of the Principles seem to abound in his Notebooks. However, commentators have been reluctant to use his unpublished entries to explicate his remarks about spiritual substances in the Principles and Dialogues for three reasons. First, it has proven difficult to reconcile the seemingly Humean bundle theory of the self in the Notebooks with Berkeley's published characterization of spirits as “active beings or principles.” Second, the fact (...) that Berkeley did not publish his Notebooks insights on mind has led some to claim that he later rejected his early views. Third, many of the Notebooks entries on mind have a ‘+’ sign next to them, which has been understood for decades to comprise a Black List of views about which Berkeley had doubts or subsequently rejected. In my dialogue, I describe how Berkeley's “congeries” account of mind (1) differs from Hume's bundle theory in a way that complements Berkeley's published remarks and (2) undercuts the claim that he later rejected his early views. Most importantly, (3) I show how a careful analysis of the British Library manuscript of the Notebooks refutes the Black List hypothesis. (shrink)

Commentators have not said much regarding Berkeley and Stoicism. Even when they do, they generally limit their remarks to Berkeley’s Siris (1744) where he invokes characteristically Stoic themes about the World Soul, “seminal reasons,” and the animating fire of the universe. The Stoic heritage of other Berkeleian doctrines (e.g., about mind or the semiotic character of nature) is seldom recognized, and when it is, little is made of it in explaining his other doctrines (e.g., immaterialism). None of this is surprising, (...) considering how Stoics are considered arch-materialists and determinists. My aim is to suggest that our understanding of Berkeley’s philosophy is improved significantly by acknowledging its underlying Stoic character. I argue that Berkeley proposes not only a semantic ontology based on assumptions of Stoic logic but also a doctrine in which perceptions or ideas are intelligible precisely because they are always embedded in the propositions of a discourse or language.

The model-theoretic argument known as Putnam´s paradox threatens our notion of truth with triviality: Almost any world can satisfy almost any theory. Formal argument and intuition are at odds. David Lewis devised a solution according to which the very stucture of the world fixes how it is to be divided into elite classes which determine the reference of any true theory. Three claims are defended: Firstly, Lewis´ proposal must be completed by an account of successful referential intentions. Secondly, contrary to (...) Catherine Elgin´s criticism of Lewis, natural properties corresponding to elite classes may play a role in sound scientific inquiry. Thirdly, despite Bas van Fraassen´s objection that the sceptic cannot consistently maintain doubts about reference, there is a promising sceptical strategy of exploiting Putnam´s results which is answered by Lewis´ account.

Egal was der heutige Tag auch bringen mag, der 1. April 2063 wird zumindest als der Tag in die Geschichte des Wissenschaftsjournalismus eingehen, der die bisher aufwändigste Berichterstattung erfahren hat. So viele Kamerateams, wie hier vor den Toren der Australian National University in Canberra, hat bisher kein wissenschaftliches Experiment anziehen können. Selbst der Knüller des Vorjahres, als es einer 48jährigen Hausfrau in einem Vorort von London gelang, mit einfachsten Küchenutensilien einen kleinen Kalte-Fusion-Reaktor herzustellen, der den Staubsauger und die Mikrowelle zuverlässig (...) mit sauberer Energie versorgte, hatte bei weitem nicht ein solches Echo in der Wissenschaftspresse erfahren. Es war zwar noch nichts über den Experimentausgang zu erfahren, trotzdem wurde freilich seit drei Tagen ununterbrochen live auf fast allen Kanälen aus Canberra darüber berichtet, dass nun zwar noch nichts zu erfahren sei, dass es aber ja sehr bald soweit sein müsse. Das Experiment, dessen Ausgang man hier so gespannt erwartete, war schon im Vorfeld hitzig diskutiert worden und überhaupt nur durch einen Sonderbeschluss der Vereinten Nationen zustande gekommen. Immerhin läuft die Vorbereitung bereits seit fast 30 Jahren, als sich mehrere Philosophen und Bürgerinitiativen zusammenschlossen, die UNO um eine endgültige Klärung einer der ältesten Fragen der Menschheit zu bitten: Was ist Bewusstsein? Und insbesondere: Ist Bewusstsein etwas anderes als physikalisch beschreibbare Zustände unseres Gehirns, oder sind alle Tatsachen letztlich physikalische Tatsachen? Dass diese Fragen trotz ihres Ehrfurcht einflößenden Alters zunehmend auf den Nägeln brannten, hatte nicht zuletzt die jüngste Entwicklung der Computertechnologie befördert. Nachdem die KI in den letzten Jahrzehnten einen großen Schritt vorwärts gemacht hatte, war man in Sorge, dass ohne endgültige begriffliche Klärung dieser Fragen unser zukünftiger Umgang mit unseren elektronischen Helfern auf moralisch unsicherem Boden stehen könne. Man hatte sich daher nach langer Abwägung der ethischen Aspekte dieses Experiments dazu entschieden, ein gerade neugeborenes Waisenkind in einem völlig schwarz-weiß-grauen Raum groß werden zu lassen, sorgsam darum bemüht, dass die kleine Mary (so hatte man das Mädchen in Anlehnung an die Protagonistin einer fiktiven philosophischen Geschichte genannt) keine Farben zu Gesicht bekommt..

I critically assess Stephen Yablo’s claim that cassinis are ovals is an a posteriori conceptual necessity. One does not know it simply by mastering the relevant concepts but by substantial empirical scrutiny. Yablo represents narrow content by would have turned out -conditionals. An epistemic reading of such conditionals does not bear Yablo’s claim. Two metaphysically laden readings are considered. In one reading, Yablo’s conditionals test under what circumstances concepts remain the same while their extensions diverge. As an alternative, I develop (...) a more literal metaphysical interpretation: Yablo’s conditionals draw on scenarios which are qualitatively identical to some original situation. None of these interpretations sustains Yablo’s core thesis. (shrink)

I criticize Yamada's account of rule-following. Yamada's conditions are not necessary. And he misses the deepest level of the rule-following considerations: how meaning rules come about.

Many authors hold that we cannot have the kind of free will that we seem to have. This article spells out and defends that kind of free will. Most libertarians hold that a free action involves a probabilistic process at some stage. Like the compatibilists, I hold that this is not only not required for free will but even reduces or excludes freedom. But contrary to the compatibilist and contrary to most libertarians, I claim that free will requires that we (...) can bring about events that have no preceding cause. That is what our experience suggests, and there are no beliefs that contradict this and are justified. (shrink)

In a series of articles, David Barnett (2006, 2009, 2010) has developed a general theory of conditionals. The grand aim is to reconcile the two main rivals: a suppositional and a truth-conditional view (Barnett 2006, 521). While I confine my critical discussion to counterfactuals, I will give some hints how they might spell trouble for his suppositional view in general.
