The Causal Exclusion Argument

Jaegwon Kim’s causal exclusion argument says that if all physical effects have sufficient physical causes, and no physical effects are caused twice over by distinct physical and mental causes, there cannot be any irreducible mental causes. In addition, Kim has argued that the nonreductive physicalist must give up completeness, and embrace the possibility of downward causation. This paper argues first that this extra argument relies on a principle of property individuation, which the nonreductive physicalist need not accept, and second that once we get clear on overdetermination, there is a way to reject the exclusion principle upon which the causal exclusion argument depends, but third that this should not lead to the belief that mental causation is easily accounted for in terms of counterfactual dependencies.     

The Truthmaking Argument Against Dispositionalism

According to dispositionalism, de re modality is grounded in the intrinsic natures of dispositional properties. Those properties are able to serve as the ground of de re modal truths, it is said, because they bear a special relation to counterfactual conditionals, one of truthmaking. However, because dispositionalism purports to ground de re modality only on the intrinsic natures of dispositional properties, it had better be the case that they do not play that truthmaking role merely in virtue of their being embedded in some particular, extrinsic causal context. This paper examines a recent argument against dispositionalism that purports to show that the intrinsicality of that relation cannot be maintained, due to the ceteris paribus nature of the counterfactuals that dispositions make‐true. When two prominent responses are examined, both are found wanting: at best, they require unjustified special pleading, and at worst, they amount to little more than ad hoc conceptual trickery. 1     

The Empirical Argument Against Virtue

The virtues are under fire. Several decades’ worth of social psychological findings establish a correlation between human behavior and the situation moral agents inhabit, from which a cadre of moral philosophers concludes that most moral agents lack the virtues. Mark Alfano and Christian Miller introduce novel versions of this argument, but they are subject to a fatal dilemma. Alfano and Miller wrongly assume that their requirements for virtue apply universally to moral agents, who vary radically in their psychological, physiological, and personal situations; I call this the ‘content problem.’ More troubling, however, the content problem leads to what I call the ‘structural problem:’ Alfano and Miller each structure their argument against the virtues as a modus tollens argument and, owing to the breadth of the content problem, each must constrain their argument with a ceteris paribus clause. But the ceteris paribus clause precludes each argument’s validity. More important, however, the resulting conception of virtue implicitly endorsed by Alfano and Miller holds that virtues are idealized models; but since idealized models do not even purport accurately to describe (much of) the world, neither novel version of EAV gains any empirical traction against the virtues. The upshot is an old story whose moral has yet, within the empirical study of the virtues, adequately to be internalized: it is imperative that the empirical observation of character traits proceed via longitudinal studies.     

The Coherence Argument Against Conditionalization

I re-examine Coherence Arguments (Dutch Book Arguments, No Arbitrage Arguments) for diachronic constraints on Bayesian reasoning. I suggest to replace the usual game–theoretic coherence condition with a new decision–theoretic condition ('Diachronic Sure Thing Principle'). The new condition meets a large part of the standard objections against the Coherence Argument and frees it, in particular, from a commitment to additive utilities. It also facilitates the proof of the Converse Dutch Book Theorem. I first apply the improved Coherence Argument to van Fraassen's (1984) Reflection principle. I then point out the failure of a Coherence Argument that is intended to support Conditionalization as a naive, universal, update rule. I also point out that Reflection is incompatible with the universal use of Conditionalization thus interpreted. The Coherence Argument therefore defeats the naive view on Bayesian learning that it was originally designed to justify. This revised version was published online in August 2006 with corrections to the Cover Date.     

The Paraphrase Argument Against Collective Actions

This paper is about the status of collective actions. According to one view, collective actions metaphysically reduce to individual actions because sentences about collective actions are merely a shorthand for sentences about individual actions. I reconstruct an argument for this view and show via counterexamples that it is not sound. The argument relies on a paraphrase procedure to unpack alleged shorthand sentences about collective actions into sentences about individual actions. I argue that the best paraphrase procedure that has been put forward so far fails to produce adequate results.     

Living in Harmony: Nominalism and the Explanationist Argument for Realism

According to the indispensability argument, scientific realists ought to believe in the existence of mathematical entities, due to their indispensable role in theorising. Arguably the crucial sense of indispensability can be understood in terms of the contribution that mathematics sometimes makes to the super‐empirical virtues of a theory. Moreover, the way in which the scientific realist values such virtues, in general, and draws on explanatory virtues, in particular, ought to make the realist ontologically committed to abstracta. This paper shows that this version of the indispensability argument glosses over crucial detail about how the scientific realist attempts to generate justificatory commitment to unobservables. The kind of role that the Platonist attributes to mathematics in scientific reasoning is compatible with nominalism, as far as scientific realist arguments are concerned.     

The Unfair Burdens Argument Against Carbon Pricing

Carbon pricing is one of the most politically important approaches for the mitigation of climate change in the world today. Most political actors who are not committed to climate change denial favor carbon pricing, either as emissions trading or carbon taxation. In this article, I argue that carbon pricing should be considered unfair in most of its forms. I present a line of criticism called the Unfair Burdens Argument. It states that the most politically relevant ways to price carbon needlessly burden the less affluent more than the more affluent. This is unfair because, among other things, the more affluent have on average done more to create the problem of climate change in the first place. Principles for the fair distribution of burdens under climate change mitigation like the Polluter Pays Principle, which were thought to support carbon pricing, turn out to speak against it, when interpreted properly. Although the Unfair Burdens Argument on its own cannot show that carbon pricing is impermissible, it offers important clues for what a morally permissible form of climate change mitigation would look like.     

Against the Vagueness Argument

In this paper I offer a counterexample to the so called vagueness argument against restricted composition. This will be done in the lines of a recent suggestion by Trenton Merricks, namely by challenging the claim that there cannot be a sharp cut-off point in a composition sequence. It will be suggested that causal powers which emerge when composition occurs can serve as an indicator of such sharp cut-off points. The main example will be the case of a heap. It seems that heaps might provide a very plausible counterexample to the vagueness argument if we accept the idea that four grains of sand is the least number required to compose a heap—the case has been supported by W. D. Hart. My purpose here is not to put forward a new theory of composition, I only wish to refute the vagueness argument and point out that we should be wary of arguments of its form.

Closed Causal Loops and the Bilking Argument

The most potentially powerful objection to the possibility oftime travel stems from the fact that it can, under the right conditions, give rise to closedcausal loops, and closed causal loops can be turned into self-defeating causal chains;folks killing their infant selves, setting out to destroy the world before they were born,and the like. It used to be thought that such chains present paradoxes; the receivedwisdom nowadays is that they give rise to physical anomalies in the form of inexplicably correlated events. I argue against the received wisdom. I can find nothing in them that argues against the possibility (even, the probability) of time travel.     

The Anthropic Argument Against the Existence of God

Sophia - If God is morally perfect then He must perform the morally best actions, but creating humans is not the morally best action. If this line of reasoning can be maintained then the mere fact...

A Cantorian Argument Against Infinitesimals

In 1887 Georg Cantor gave an influential but cryptic proof of theimpossibility of infinitesimals. I first give a reconstruction ofCantor's argument which relies mainly on traditional assumptions fromEuclidean geometry, together with elementary results of Cantor's ownset theory. I then apply the reconstructed argument to theinfinitesimals of Abraham Robinson's nonstandard analysis. Thisbrings out the importance for the argument of an assumption I call theChain Thesis. Doubts about the Chain Thesis are seen to render thereconstructed argument inconclusive as an attack on the infinitelysmall.

A Defence Of Connectionism Against The "Syntactic' Argument

In "Representations without Rules, Connectionism and the Syntactic Argument', Kenneth Aizawa argues against the view that connectionist nets can be understood as processing representations without the use of representation-level rules, and he provides a positive characterization of how to interpret connectionist nets as following representation-level rules. He takes Terry Horgan and John Tienson to be the targets of his critique. The present paper marshals functional and methodological considerations, gleaned from the practice of cognitive modelling, to argue against Aizawa's characterization of how connectionist nets may be understood as making use of representation-level rules.     

A Deranged Argument Against Public Languages

Are there really such things as public languages? Are things like English and Urdu mere myths? I urge that, despite an intriguing line of thought which may be extracted from Davidson’s ‘A Nice Derangement of Epitaphs’, philosophers are right to countenance such things in their final ontology. The argument rebutted, which I concede may not have been one which Davidson himself ultimately embraced, is that knowledge of a public language is neither necessary nor sufficient for successful conversational interaction, so that such shared languages are explanatorily otiose. In particular, the ability of interlocutors to communicate in the face of linguistic novelty and error seems to support this conclusion. I respond with two main points. First, initial impressions aside, knowledge of things like English and Urdu is explanatorily necessary. Second, even if successful conversation could be explained without positing such knowledge, we have other reasons to take public languages ontologically seriously. The ultimate result is that what I label a ‘deranged argument against public languages’ is unsound.
