o (2000), 243). In particular, the idea is that binding interactions between the relevant expressions and natural lan- guage quantifiers are best explained by the hypothesis that those expressions harbor hidden but bindable variables. Recently, however, Herman Cappelen and Ernie Lepore have rejected such binding arguments for the presence of hid- den variables on the grounds that they overgeneralize — that, if sound, such arguments would establish the presence of hidden variables in all sorts of ex- pressions where (...) it is implausible that they exist (Cappelen and Lepore (2005), Cappelen and Lepore (2002)).1 In what follows we respond to Cappelen’s and Lepore’s attempted reductio by bringing out crucial disanalogies between cases where the bindingargument is successful and cases where it is not. But we have a deeper purpose than merely to respond to Cappelen and Lepore: we think the attempted reductio goes wrong by not taking sufficiently seriously the nature of the binding relation that holds between quantifiers and arguments/variables, and that our criticism will serve to highlight the nature and importance of this relation.

What is the proper way to draw the semantics-pragmatics distinction, and is what is said by a speaker ever enriched by pragmatics? An influential but controversial answer to the latter question is that the inputs to semantic interpretation contains representations of every contribution from context that is relevant to determining what is said, and that pragmatics never enriches the output of semantic interpretation. The proposal is bolstered by a controversial argument from syntactic binding designed to detect hidden syntactic (...) structure. The following contains an exposition and consideration of the argument. (shrink)
The correct locus (or loci) of binding theory has been a matter of much discussion. Theories can be seen as varying along at least two dimensions. The rst is whether binding theory is con gurationally determined (that is, the theory exploits the geometry of a phrase marker, appealing to such purely structural notions as c-command and government) or whether the theory depends rather on examining the relations between items selected by a predicate (where by selection I am intending (...) to cover everything from semantic dependencies to syntactic subcategorization). The second is the level of grammar on which binding is de ned. Attempting to roughly equate levels across di erent theories, suggestions have included the semantics/lexical conceptual structure (Jackendo 1992), thematic structure (Jackendo 1972, Wilkins 1988), argument structure/D-structure/initial grammatical relations (Manning 1994, Belletti and Rizzi 1988, Perlmutter 1984), surface syntax/grammatical relations, logical form, linear order, pragmatics (Levinson 1991), and discourse (Iida 1992). The data is su ciently varied and complex that many theories end up as mixtures, variously employing a combination of elements along both dimensions (for instance, Chomsky (1986) relies purely on con gurational notions for the relationship between an anaphor and its antecedent, but uses concepts from selection in the de nition of the binding domain of an anaphor). LFG has always rejected a con gurational account of binding.

Relative to an ordinary context, an utterance of the sentence ‘Everything is in the car’ communicates a proposition about a restricted domain. But how does this work? One possibility is that quantifier expressions like 'everything' are context sensitive and range over different domains in different contexts. Another possibility is that quantifier expressions are not context sensitive, but have a fixed, absolutely general meaning, and ordinary utterances communicate a restricted content via Gricean mechanisms. I argue that, contrary to received opinion, the (...) latter view has both a number of methodological and also intuitive advantages over the former. I then reply to three objections to the latter view: the bindingargument (due to Stanley and Szabo), the availability-based attack (due to Recanati), and an argument based on Recanati’s scope principle.

Most theories of binding in most syntactic frameworks assume that the same notion of surface obliqueness that identi es the subject of a clause is also used for obliqueness conditions on re exive binding For instance in GB Chomsky binding theory is standardly de ned on S structure so that in Nancy can bind herself due to the c commanding con guration that also makes Nancy the subject of the sentence..
This paper discusses several case studies that illustrate the relationship between the philosophy of language and three branches of linguistics: syntax, semantics, and pragmatics. Among other things, I identify binding arguments in the linguistics literature preceding (Stanley 2000), and I invent binding arguments to evaluate various semantic and pragmatic theories of belief ascriptions.
A generally ignored feature of Aristotle’s famous function argument is its reliance on the claim that practitioners of the crafts (technai) have functions: but this claim does important work. Aristotle is pointing to the fact that we judge everyday rational agency and agents by norms which are independent of their contingent desires: a good doctor is not just one who happens to achieve his personal goals through his work. But, Aristotle argues, such norms can only be binding on (...) individuals if human rational agency as such is governed by objective teleological norms. . (shrink)
Since Kaplan’s "Demonstratives", it has become a common-place to distinguish between the character and content of an expression, where the content of an expression is what it contributes to "what is said" by sentences containing that expression, and the character gives a rule for determining, in a context, the content of an expression. A tacit assumption of theories of character has been that character is autonomous from content – that semantic evaluation starts with character, adds context, and then derives content. (...) One consequence of this autonomy thesis is that the rules for character can contain no variables bound by content-level operators elsewhere in the sentence. Tacit appeal to this consequence features essentially both in Jason Stanley’s recent argument that all contextual ambiguity must be linked to "elements in the actual syntactic structure of the sentence uttered" in his "Context and Logical Form" and in my arguments against character-based theories of complex demonstratives in my "Complex Demonstratives". However, I argue here that the autonomy thesis is unmotivated, and show that we can separate Kaplan’s notion of character into two independent components: an aspect of meaning which is context-sensitive, and an aspect of meaning that is exempted from scopal interactions with other operators. The resulting semantic framework allows constructions similar to Kaplan’s rejected notion of "monsters begat by elegance", but which are both more empirically adequate and more theoretically versatile. Having made the distinction between context-sensitivity and autonomy from scopal interaction, I show how it allows binding into the character of expressions and hence undermines the immediate success of both Stanley’s argument and my former argument against character-based theories of complex demonstratives, and discuss briefly the prospects for reinstating modified versions of those arguments. Finally, I show how that same distinction allows a defusing of Kripke’s modal argument against a descriptive theory of names. Once autonomy from semantic interaction is separated from context-sensitivity, the first of those two alone can be used to capture the modal rigidity of proper names.. (shrink)
Our perception of external features comprises, among others, functional and phenomenological levels. At the functional level, the perceiver’s mind processes external features according to its own causal- functional organization. At the phenomenological level, the perceiver has consciousness of external features. The question of this paper is: How do the functional and the phenomenological levels of perception relate to each other? The answer I propose is that functional states of specifically perceptual attention constitute the necessary basis for the arising of consciousness (...) in a perceiver. -/- Widely studied within cognitive psychology, perceptual attention is still awaiting a thoroughgoing philosophical treatment. The paper presents and draws upon Anne Treisman’s feature-integration theory of attention (cf. A. Treisman & G. Gelade, “A Feature-Integration Theory of Attention,” Cognitive Psychology, 12, 1980. Pp. 97-136). According to this theory, attentional mechanisms are responsible for the binding of perceptual features into coherent and stable objects of perception. By itself, I will claim, the theory of feature integration does not allow a straightforward reduction of consciousness to the functional processing underlying it. However, on the basis of Treisman’s theory we can produce a methodological argument for endorsing the non-reductivist thesis that attentional states constitute the necessary basis for the arising of consciousness in a perceiver. The paper closes by presenting this argument, according to which the thesis is implied by a unified account of the common representational natures of attentional and conscious states. (shrink)
It is necessary to distinguish among representations caused directly by perception, representations of past perceptions in long-term memory, the representations underlying linguis- tic utterances, and the surface phonological and grammatical structures of sentences. The target article dealt essentially with predicate-argument structure at the first of these levels of representation. Discussion of the commentaries mainly involves distinguishing among various applications of the term “predicate”; clarifying the assumed relationship between classical FOPL and language; clarifying the status of unique individuals as conceived (...) by humans; and addressing the issues of motion-perception, binding between object-percepts and predicate-percepts, and target-driven versus stimulus-driven attention.

Many philosophers and game theorists have been struck by the thought that the backward induction argument (BIA) for the finite iterated pris- oner’s dilemma (FIPD) recommends a course of action which is grossly counter-intuitive and certainly contrary to the way in which people behave in real-life FIPD-situations (Luce and Raiffa 1957, Pettit and Sugden 1989, Bovens 1997).1 Yet the backwards induction argument puts itself forward as binding upon rational agents. What are we to conclude from this? Is (...) it that people in real-life FIPD-situations tend to act irrationally and that our own intuitions about what to do in such situations reveal us to be irra- tional? Alternatively, should we abandon game theory and decision theory as a guide to rationality? Or are there other ways in which the apparent disparity between the dictates of rationality and the reality of reasoning can be accommodated? (shrink)
If an argument can be reconstructed in at least two different ways, then which reconstruction is to be preferred? In this paper I address this problem of argument reconstruction in terms of Ryle’s infinite regress argument against the view that knowledge-how requires knowledge-that. First, I demonstrate that Ryle’s initial statement of the argument does not fix its reconstruction as it admits two, structurally different reconstructions. On the basis of this case and infinite regress arguments generally, I (...) defend a revisionary take on argument reconstruction: argument reconstruction is mainly to be ruled by charity (viz. by general criteria which arguments have to fulfil in order to be good arguments) rather than interpretation.

This article examines argument structures and strategies in pro and con argumentation about the possibility of human-level artificial intelligence (AI) in the near term future. It examines renewed controversy about strong AI that originated in a prominent 1999 book and continued at major conferences and in periodicals, media commentary, and Web-based discussions through 2002. It will be argued that the book made use of implicit, anticipatory refutation to reverse prevailing value hierarchies related to AI. Drawing on Perelman and Olbrechts-Tyteca's (...) (1969) study of refutational argument, this study considers points of contact between opposing arguments that emerged in opposing loci, dissociations, and casuistic reasoning. In particular, it shows how perceptions of AI were reframed and rehabilitated through metaphorical language, reversal of the philosophical pair artificial/natural, appeals to the paradigm case, and use of the loci of quantity and essence. Furthermore, examining responses to the book in subsequent arguments indicates the topoi characteristic of the rhetoric of technology advocacy. (shrink)
Where does the necessity that seems to accompany causal inferences come from? “Why [do] we conclude that […] particular causes must necessarily have such particular effects?” (Hume 2002, 1.3.2.15) In 1.3.6 of the Treatise, Hume entertains the possibility that this necessity is a function of reason. However, he eventually dismisses this possibility, where this dismissal consists of Hume’s “negative” argument concerning induction. This argument has received, and continues to receive, a tremendous amount of attention. How could causal inferences (...) be justified if they are not justified by reason? If we believe that p causes q, isn’t it reason that allows us to conclude q when we see p with some assurance, i.e., with some necessity? (shrink)
J. Howard Sobel devotes seventy pages of his wide-ranging analysis of theistic arguments to a critique of the cosmological argument. Although the focus of that critique falls on the Leibnizian argument, he also offers in passing some criticisms of the kalam cosmological argument. Sobel does not challenge the causal premiss insofar as "begins to exist" means "has a first time of its existence." Rather he disputes the arguments and evidence for the fact of the universe's beginning. I (...) show that Sobel's rebuttals of the philosophical arguments against the infinitude of the past are in various ways misconceived or fallacious and that his response to the empirical evidence for the beginning of the universe involves a gratuitous and radical revision of contemporary astrophysical cosmogony.

John Searle's Chinese room argument is perhaps the most influential andwidely cited argument against artificial intelligence (AI). Understood astargeting AI proper â claims that computers can think or do thinkâ Searle's argument, despite its rhetorical flash, is logically andscientifically a dud. Advertised as effective against AI proper, theargument, in its main outlines, is an ignoratio elenchi. It musterspersuasive force fallaciously by indirection fostered by equivocaldeployment of the phrase "strong AI" and reinforced by equivocation on thephrase "causal powers" (...) (at least) equal to those of brains." On a morecarefully crafted understanding â understood just to targetmetaphysical identification of thought with computation ("Functionalism"or "Computationalism") and not AI proper the argument is still unsound,though more interestingly so. It's unsound in ways difficult for high churchâ "someday my prince of an AI program will come" â believersin AI to acknowledge without undermining their high church beliefs. The adhominem bite of Searle's argument against the high church persuasions of somany cognitive scientists, I suggest, largely explains the undeserved reputethis really quite disreputable argument enjoys among them.

In this paper I present a new argument against internalist theories of practical reason. My argument is inpired by Frank Jackson's celebrated Knowledge Argument. I ask what will happen when an agent experiences pain for the first time. Such an agent, I argue, will gain new normative knowledge that internalism cannot explain. This argument presents a similar difficulty for other subjectivist and constructivist theories of practical reason and value. I end by suggesting that some debates in (...) meta-ethics and in the philosophy of mind might be more closely intertwined than philosophers in either area would like to believe. (shrink)
One of Kripke's fundamental objections to descriptivism was that the theory misclassifies certain _a posteriori_ propositions expressed by sentences involving names as _a priori_. Though nowadays very few philosophers would endorse a descriptivism of the sort that Kripke criticized, many find two-dimensional semantics attractive as a kind of successor theory. Because two-dimensionalism needn't be a form of descriptivism, it is not open to the epistemic argument as formulated by Kripke; but the most promising versions of two-dimensionalism are open to (...) a close relative of that argument.

In this paper, I argue that Kant's famous critique of the Ontological Argument largely begs the question against that argument, and is no better when supplemented by the modern quantificational analysis of "exists." In particular, I argue that the claim, common to Hume and Kant, that conceptual truths can never entail substantive existential claims is false,and thus no ground for rejecting the Ontological Argument.
The Chomskian holds that the grammars that linguists produce are about human psycholinguistic structures, i.e. our mastery of a grammar, our linguistic competence. But if we encountered Martians whose psycholinguistic processes differed from ours, but who nevertheless produced sentences that are extensionally equivalent to the set of sentences in our English and shared our judgements on the grammaticality of various English sentences, then we would count them as being competent in English. A grammar of English is about what the Martians (...) and we share. In this note, I argue that a recent attack on the Martian Argument by Laurence fail to mitigate its force. (shrink)
Marginal humans are not rational yet we still think they are morally considerable. This is inconsistent with denying animals moral status on the basis of their irrationality. Therefore, either marginal humans and animals are both morally considerable or neither are. In this paper I consider a major objection to this argument: that species is a relevant difference between humans animals.
Derk Pereboom's Four-Case Argument is among the most famous and resilient manipulation arguments against compatibilism. I contend that its resilience is not a function of the argument's soundness but, rather, the ill-gotten gain from an ambiguity in the description of the causal relations found in the argument's foundational case. I expose this crucial ambiguity and suggest that a dilemma faces anyone hoping to resolve it. After a thorough search for an interpretation which avoids both horns of this (...) dilemma, I conclude that none is available. Rather, every metaphysically coherent interpretation invites either a hard- or soft-line reply to Pereboom's argument. I then consider a recharacterization of the dilemma which seems to clear the way for the defence of a revised Four-Case Argument. I address this rejoinder by identifying a still more fundamental problem shared by all viable interpretations of the manipulation cases, showing that each involves a type of manipulation which undermines the victim's agency. Because this diagnosis supports a soft-line reply to every viable interpretation of the argument and can be endorsed by any compatibilist, I consider it the final piece of the Soft-line Solution to the Four-Case Argument. Finally, I suggest a new taxonomy of manipulation arguments, arguing that none that employs the suppressive variety of manipulation found in Pereboom's argument offers a threat to compatibilism.

One argument for reductive physicalism, the explanatory argument, rests on its ability to explain the vast and growing body of acknowledged psychophysical correlations. Jaegwon Kim has recently levelled four objections against the explanatory argument. I assess all of Kim's objections, showing that none is successful. The result is a defence of the explanatory argument for physicalism.
Rationality (or something similar) is usually given as the relevant difference between all humans and animals; the reason humans do but animals do not deserve moral consideration. But according to the Argument from Marginal Cases not all humans are rational, yet if such (marginal) humans are morally considerable despite lacking rationality it would be arbitrary to deny animals with similar capacities a similar level of moral consideration. The slippery slope objection has it that although marginal humans are not strictly (...) speaking morally considerable, we should give them moral consideration because if we do not we will slide down a slippery slope where we end up by not giving normal humans due consideration. I argue that this objection fails to show that marginal humans have the kind of direct moral status proponents of the slippery slope argument have in mind. (shrink)
The recent debate surrounding scientific realism has largely focused on the “no miracles” argument (NMA). Indeed, it seems that most contemporary realists and anti-realists have tied the case for realism to the adequacy of this argument. I argue that it is mistake for realists to let the debate be framed in this way. Realists would be well advised to abandon the NMA altogether and pursue an alternative strategy, which I call the “local strategy”.
It is argued that the explanatory gap argument, according to which it is fundamentally impossible to explain qualitative mental states in a physicalist theory of mind, is unsound. The main argument in favour of the explanatory gap is presented, which argues that an identity statement of mind and brain has no explanatory force, in contrast to "normal" scientific identity statements. Then it is shown that "normal" scientific identity statements also do not conform to the demands set by the (...) proponent of the explanatory gap. Rather than accept all such gaps, it is argued that we should deny the explanatory gap in a physicalist theory of mind. (shrink)
The luck argument raises a serious challenge for libertarianism about free will. In broad outline, if an action is undetermined, then it appears to be a matter of luck whether or not one performs it. And if it is a matter of luck whether or not one performs an action, then it seems that the action is not performed with free will. This argument is most effective against event-causal accounts of libertarianism. Recently, Christopher Franklin (2011) has defended event-causal (...) libertarianism against four formulations of the luck argument. I will argue that three of Franklin’s responses are unsuccessful and that there are important versions of the luck challenge that his defense has left unaddressed. (shrink)
Proponents of the argument from regress maintain that the existence of Instrumental Value is sufficient to establish the existence of Intrinsic Value. It is argued that the chain of instrumentally valuable things has to end somewhere. Namely with intrinsic value. In this paper, I shall argue something a little more modest than this. I do not want to argue that the regress argument proves that there is intrinsic value but rather that it proves that the idea of intrinsic (...) value is a necessary part of our thinking about moral value.

In this paper, I examine Kant’s famous objection to the ontological argument: existence is not a determination. Previous commentators have not adequately explained what this claim means, how it undermines the ontological argument, or how Kant argues for it. I argue that the claim that existence is not a determination means that it is not possible for there to be non-existent objects; necessarily, there are only existent objects. I argue further that Kant’s primary target is not ontological arguments (...) as such but the metaphysical view they presuppose: that God necessarily exists in virtue of his essence being contained in, or logically entailed by, his essence. I show that this view of divine necessity requires the assumption that existence is a determination, and I show that Descartes and Leibniz are implicitly committed to this in their published versions of the ontological argument. I consider the philosophical motivations for the claim that existence is a determination and then I argue that Kant’s argument in the Critique of Pure Reason only undermines some of them. (shrink)
Think of the last thing someone did to you to seriously harm or offend you. And now imagine, so far as you can, becoming fully aware of the fact that his or her action was the causally inevitable result of a plan set into motion before he or she was ever even born, a plan that had no chance of failing. Should you continue to regard him or her as being morally responsible—blameworthy, in this case—for what he or she did? (...) Many have thought that, intuitively, you should not. Recently, Alfred Mele has employed this line of thought to mount what many have taken to be a powerful argument for incompatibilism: the “Zygote Argument”. However, in interesting new papers, John Martin Fischer and Stephen Kearns have each independently argued that the Zygote Argument fails. As I see it, the criticisms of Fischer and Kearns reveal some important questions about how the argument is meant to be—or how it would best be—understood. Once we make a slight (but important) modification to the argument, however, I think we will be able to see that the criticisms of Fischer and Kearns do not detract from its substantial force.

David Chalmers' dancing qualia argument is intended to show that phenomenal experiences, or qualia, are organizational invariants. The dancing qualia argument is a reductio ad absurdum, attempting to demonstrate that holding an alternative position, such as the famous inverted spectrum argument, leads one to an implausible position about the relation between consciousness and cognition. In this paper, we argue that Chalmers' dancing qualia argument fails to establish the plausibility of qualia being organizational invariants. Even stronger, we (...) will argue that the gap in the argument cannot be closed. (shrink)
The consequence argument for the incompatibility of free action and determinism has long been under attack, but two important objections have only recently emerged: Warfield’s modal fallacy objection and Campbell’s no past objection. In this paper, I explain the significance of these objections and defend the consequence argument against them. First, I present a novel formulation of the argument that withstands their force. Next, I argue for the one controversial claim on which this formulation relies: the trans-temporality (...) thesis. This thesis implies that an agent acts freely only if there is one time at which she is able to perform an action and a distinct time at which she actually performs it. I then point out that determinism, too, is a thesis about trans-temporal relations. I conclude that it is precisely because my formulation of the consequence argument emphasizes trans-temporality that it prevails against the modal fallacy and no past objections. (shrink)
The cosmological argument for God’s existence has a long history, but perhaps the most influential version of it has been the argument from contingency. This is the version that Frederick Copleston pressed upon Bertrand Russell in their famous debate about God’s existence in 1948 (printed in Russell’s 1957 Why I am not a Christian). Russell’s lodges three objections to the Thomistic argument.
In this paper, I argue that the ultimate argument for Scientific Realism, also known as the No-Miracles Argument (NMA), ultimately fails as an abductive defence of Epistemic Scientific Realism (ESR), where (ESR) is the thesis that successful theories of mature sciences are approximately true. The NMA is supposed to be an Inference to the Best Explanation (IBE) that purports to explain the success of science. However, the explanation offered as the best explanation for success, namely (ESR), fails to (...) yield independently testable predictions that alternative explanations for success do not yield. If this is correct, then there seems to be no good reason to prefer (ESR) over alternative explanations for success. (shrink)
According to the incentives argument, inequalities in material goods are justifiable if they are to the benefit of the worst off members of society. In this paper, I point out what is easily overlooked, namely that inequalities are justifiable only if they are to the overall benefit of the worst off, that is, in terms of both material and social goods. I then address the question how gains in material goods can be weighed against probable losses in social goods. (...) The ultimate criterion, so my idea, is how these gains and losses affect a person’s ability to reach her goals in life. Based on the idea that goals in life cannot be taken as given, I conclude that the absolute material gains are negligible compared to the losses of social goods and the disadvantage in the relative position caused by material inequalities.

The idea that formal geometry derives from intuitive notions of space has appeared in many guises, most notably in Kant’s argument from geometry. Kant claimed that an a priori knowledge of spatial relationships both allows and constrains formal geometry: it serves as the actual source of our cognition of principles of geometry and as a basis for its further cultural development. The development of non-Euclidean geometries, however, seemed to definitely undermine the idea that there is some privileged relationship between (...) our spatial intuitions and mathematical theory. This paper’s aim is to look at this longstanding philosophical issue through the lens of cognitive science. Drawing on recent evidence from cognitive ethology, developmental psychology, neuroscience and anthropology, I argue for an enhanced, more informed version of the argument from geometry: humans share with other species evolved, innate intuitions of space which serve as a vital precondition for geometry as a formal science.

According to the Argument from Disagreement (AD) widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by moral facts, either because there are no such facts or because there are such facts but they fail to influence our moral opinions. In an innovative paper, Gustafsson and Peterson (Synthese, published online 16 October, 2010) study the argument by means of computer simulation of opinion dynamics, relying on the well-known model of Hegselmann and Krause (...) (J Artif Soc Soc Simul 5(3):1–33, 2002; J Artif Soc Soc Simul 9(3):1–28, 2006). Their simulations indicate that if our moral opinions were influenced at least slightly by moral facts, we would quickly have reached consensus, even if our moral opinions were also affected by additional factors such as false authorities, external political shifts and random processes. Gustafsson and Peterson conclude that since no such consensus has been reached in real life, the simulation gives us increased reason to take seriously the AD. Our main claim in this paper is that these results are not as robust as Gustafsson and Peterson seem to think they are. If we run similar simulations in the alternative Laputa simulation environment developed by Angere and Olsson (Angere, Synthese, forthcoming and Olsson, Episteme 8(2):127–143, 2011) considerably less support for the AD is forthcoming.

It is argued that, contrary to prevailing opinion, Bas van Fraassen nowhere uses the argument from underdetermination in his argument for constructive empiricism. It is explained that van Fraassen’s use of the notion of empirical equivalence in The Scientific Image has been widely misunderstood. A reconstruction of the main arguments for constructive empiricism is offered, showing how the passages that have been taken to be part of an appeal to the argument from underdetermination should actually be interpreted.
I defend a hard-line reply to Derk Pereboom’s four-case manipulation argument. Pereboom accuses compatibilists who take a hard-line reply to his manipulation argument of adopting inappropriate initial attitudes towards the cases central to his argument. If Pereboom is correct he has shown that a hard-line response is inadequate. Fortunately for the compatibilist, Pereboom’s list of appropriate initial attitudes is incomplete and at least one of the initial attitudes he leaves out provides room for a revised hard-line reply (...) to be successfully mounted against the multiple-case argument.

Timothy O’Connor presents a novel and powerful version of the cosmological argument from contingency. What distinguishes his argument is that it does not depend on the Principle of Sufficient Reason. This version thus avoids powerful objections facing the Principle. We present and develop the argument, strengthening it in various ways. We fill in big gaps in the argument and answer criticisms. These include the criticisms that O’Connor considers as well as new criticisms. We explain how his (...) replies to a Kantian criticism and to the demand for contrastive explanation fail, and properly answer the criticism and the demand. We develop two new criticisms, the objection from opaqueness and the objection from constitution, and explain how these objections can be answered. (shrink)
In this paper I will examine two responses to the argument from marginal cases; the argument from kinds and the similarity argument. I will argue that these arguments are insufficient to show that all humans have moral status but no animals do. This does not prove that animals have moral status but it does shift the burden of proof onto those who want to maintain that all humans are morally considerable, but no animals are.
Searle's Chinese room argument is analyzed from a cognitive point of view. The analysis is based on a newly developed model of conceptual integration, the many space model proposed by Fauconnier and Turner. The main point of the analysis is that the central inference constructed in the Chinese room scenario is a result of a dynamic, cognitive activity of conceptual blending, with metaphor defining the basic features of the blending. Two important consequences follow: (1) Searle's recent contention that syntax (...) is not intrinsic to physics turns out to be a slightly modified version of the old Chinese room argument; and (2) the argument itself is still open to debate. It is persuasive but not conclusive, and at bottom it is a topological mismatch in the metaphoric conceptual integration that is responsible for the non-conclusive character of the Chinese room argument.

According to the cosmological argument, there must be a self-existent being, because, if every being were a dependent being, we would lack an explanation of the fact that there are any dependent beings at all, rather than nothing. This argument faces an important, but little-noticed objection: If self-existent beings may exist, why may not also self-explanatory facts also exist? And if self-explanatory facts may exist, why may not the fact that there are any dependent beings be a self-explanatory (...) fact? And if that fact is self-explanatory, why make recourse to self-existent beings? This line of questioning is surprisingly hard to answer, but I find resources for an answer in Bertrand Russell's logical atomism. (shrink)
Richard Swinburne (Swinburne and Shoemaker 1984; Swinburne 1986) argues that human beings currently alive have non{bodily immaterial parts called souls. In his main argument in support of this conclusion (modal argument), roughly speaking, from the assumption that it is logically possible that a human being survives the destruction of their body and a few additional premises, he infers the actual existence of souls. After a brief presentation of the argument we describe the main known objection to it, (...) called the substitution objection (SO for short), which is raised by Alston and Smythe (1994), Zimmerman (1991) and Stump and Kretzmann (1996). We then explain Swinburne's response to it (1996). This constitutes a background for the discussion that follows. First, we formalize Swinburne's argument in a quantified propositional modal language so that it is logically valid and contains no tacit assumptions, clearing up some notational issues as we go. Having done that, we explain why we find Swinburne's response unsatisfactory. Next, we indicate that even though SO is quite compelling (albeit for a slightly different reason than the one given previously in the literature), a weakening of one of the premises yields a valid argument for the same conclusion and yet immune to SO. Even this version of the argument, we argue, is epistemically circular. (shrink)
Combinatory logic (Curry and Feys 1958) is a “variable-free” alternative to the lambda calculus. The two have the same expressive power but build their expressions differently. “Variable-free” semantics is, more precisely, “free of variable binding”: it has no operation like abstraction that turns a free variable into a bound one; it uses combinators—operations on functions—instead. For the general linguistic motivation of this approach, see the works of Steedman, Szabolcsi, and Jacobson, among others. The standard view in linguistics is that (...) reflexive and personal pronouns are free variables that get bound by an antecedent through some coindexing mechanism. In variable free semantics the same task is performed by some combinator that identifies two arguments of the function it operates on (a duplicator). This combinator may be built into the lexical semantics of the pronoun, into that of the antecedent, or it may be a free-floating operation applicable to predicates or larger chunks of texts, i.e. a typeshifter. This note is concerned with the case of cross-sentential anaphora. It adopts Hepple’s and Jacobson’s interpretation of pronouns as identity maps and asks how this can be extended to the cross-sentential case, assuming the dynamic semantic view of anaphora. It first outlines the possibility of interpreting indefinites that antecede non-ccommanded pronouns as existential quantifiers enriched with a duplicator. Then it argues that it is preferable to use the duplicator as a type-shifter that applies “on the fly”. The proposal has consequences for two central ingredients of the classical dynamic semantic treatment: it does away with abstraction over assignments and with treating indefinites as inherently existentially quantified. However, cross-sentential anaphora remains a matter of binding, and the idea of propositions as context change potentials is retained. (shrink)
One form of argument from analogy is identified and Stephen Barker's remarks about a second kind of argument from analogy, non-inductive (and non-deductive) argument from analogy, are used as a springboard to identify a second form. That form is then refined, explained, exemplified, and related to the first form. It is argued that there is a spectrum of different forms of argument from analogy, with the two forms identified being end points on the spectrum. Except in (...) terms of form, however, there is no reason to speak of two different kinds of argument from analogy. (shrink)
Anti-realists typically contend that truth is epistemically constrained. Truth, they say, cannot outstrip our capacity to know. Some anti-realists are also willing to make a further claim: if truth is epistemically constrained, classical logic is to be given up in favour of intuitionistic logic. Here we shall be concerned with one argument in support of this thesis - Crispin Wright's Basic Revisionary Argument, first presented in his Truth and Objectivity. We argue that the reasoning involved in the (...) class='Hi'>argument, if correct, validates a parallel argument that leads to conclusions that are unacceptable to classicists and intuitionists alike.

The paper deals with the possible readings of The Reaper Argument premisses. Some conjectures related to the Stoics’ alleged proof of the argument are discussed.
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 article questions social constructionists' claims to introduce Wittgenstein's philosophy to psychology. The philosophical fiction of a neonate Crusoe is introduced to cast doubt on the interpretations and use of the private language argument to support a new psychology developed by the constructionists. It is argued that a neonate Crusoe's viability in philosophy and apparent absence in psychology offends against the integrity of the philosophical contribution Wittgenstein might make to psychology. The consequences of accepting Crusoe's viability are explored as (...) they appear in both philosophy and psychology. (shrink)
Jerry Fodor argues for individualism and for narrow content by way of rejecting an argument based on the conceptual connections between reason-properties and action-properties. In this paper I show that Fodor’s argument fails. He is right that there is a New Logical Connections Argument to be made, and that it does show that water thoughts and XYZ thoughts are not different causal powers with respect to intentional properties of behaviors. However, the New Logical Connections Argument also (...) shows that they are not causal powers at all with respect to intentional properties ofbehaviors, and so Fodor’s argument to individualism and narrow content is unsound. Along the way I show that Fodor’s version of the New Logical Connections argument has serious problems of overkill. (shrink)
Several proponents of the interventionist theory of causation have recently argued for a neo-Russellian account of causation. The paper discusses two strategies for interventionists to be neo-Russellians. Firstly, I argue that the open systems argument – the main argument for a neo-Russellian account advocated by interventionists – fails. Secondly, I explore and discuss an alternative for interventionists who wish to be neo-Russellians: the statistical mechanical account. Although the latter account is an attractive alternative, it is argued that interventionists (...) are not able to adopt it straightforwardly. Hence, to be neo-Russellians remains a challenge to interventionists. (shrink)
I argue that Kant's and Frege's refutations of the ontological argument are more similar than has generally been acknowledged. As I clarify, for both Kant and Frege, to say that something exists is to assert of a concept that it is instantiated. With such an assertion one expresses that there is a particular relation between the instantiating object and a rational subject - a particular mode of presentation for the object in question. By its very nature such a relation (...) cannot be the property of an object and thus cannot be included in the concept of that object. Thus the ontological argument, which takes existence to be a part of the concept of the supreme being, cannot, according to Kant and Frege, succeed. A secondary goal of the paper is to illuminate what I take to be an important affinity between Kant's and Frege's views more generally: that Frege's fundamental distinction between the sense and the referent of a proposition echoes, in an important way, Kant's distinction between concepts and the formal principles for their application to experience.

J. Richard Gott III (1993) has used the “Copernican principle” to derive a probability density function for the total longevity of any phenomenon, based solely on the phenomenon’s past longevity. John Leslie (1996) and others have used an apparently similar probabilistic argument, the “Doomsday Argument,” to claim that conventional predictions of longevity must be adjusted, based on Bayes’ Theorem, in favor of shorter longevities. Here I show that Gott’s arguments are flawed and contradictory, but that one of his (...) conclusions—his delta t formula—is mathematically equivalent to Laplace’s famous (and notorious) ‘rule of succession’; moreover, Gott’s delta t formula is a plausible worst-case (if one favors greater longevity) bound in some contexts. On the other hand, the Doomsday Argument is fallacious: the argument’s Bayesian formalism is stated in terms of total duration, but all attempted real-life applications of the argument—with one exception, an application by Gott 1994—actually plug in prior probabilities for future duration; moreover, the Self-Sampling Assumption, an essential premise of the Doomsday Argument, is contradicted by the prior information in all known real-life cases. But rejecting the Doomsday Argument does not entail rejecting the possibility of learning about the future from the past. Applying the work of Bruce M. Hill (1968, 1988, 1993) and Frank P.A. Coolen (1998, 2006) in the field of non-parametric predictive inference, I propose and defend an alternative methodology for quantifying how past longevity of any phenomenon does provide evidence for future longevity. In so doing, I identify an objective standard by which to choose among counting time intervals, counting population, or counting any other measure of past longevity in predicting future longevity. This methodology forms the basis of a calculus of induction. (shrink)
There is yet one more proposed solution to the argument from evil which merits attention. Though it does have elements in common with other proposed solutions in that it postulates a justifying end to account for the existence of all evil, it is different in that evil is viewed as nothing more than a polluting by-product of the proper functioning of the laws of nature in their industrious manufacture of the summum bonum. The unimpeded functioning of the laws of (...) nature is seen as necessary for the production and creation of a justifying (indiscernible) end and evil or suffering is merely a foreseen but unfortunate by-product of this natural machinery. The place and function of evil in this solution is what is novel: it is not a greatness-making property, nor is it a punishment or warning from on high, nor is its usefulness an aesthetic or contrasting one, nor is it the result of free will. Evil is admitted as just plain evil; it itself plays no role to serve the valuable end, which is precipitated by the unimpeded operation of natural laws upon the universe. Evil here is seen to play the same role that pollution might: it is a foreseen and unfortunate consequence of the means used to produce the coveted final product. -/- Professor Clement Dore, in his book entitled Theism,[1] introduces this solution in which evil itself plays no role to serve an enormously valuable end, yet is necessitated by this end. However, in order for the theist to be in a position to defend Dore's claim, a viable interpretation of the justifying, indiscernible end, must be proposed. To assess the validity of Dore's schema, four apparently exhaustive interpretations of the justifying end will be presented. It will be argued here that each of these possible interpretations is, in one respect or another, inadequate. The result is that the concept of the justifying, indiscernible end and its relation to Dore's overall schema lacks lucidity. In addition, other problems with this solution will be discussed in order to show that severe flaws exist in the solution as a whole. (shrink)
Nick Bostrom’s ‘Simulation Argument’ purports to show that, unless we are confident that advanced ‘posthuman’ civilizations are either extremely rare or extremely rarely interested in running simulations of their own ancestors, we should assign significant credence to the hypothesis that we are simulated. I argue that Bostrom does not succeed in grounding this constraint on credence. I first show that the Simulation Argument requires a curious form of selective scepticism, for it presupposes that we possess good evidence for (...) claims about the physical limits of computation and yet lack good evidence for claims about our own physical constitution. I then show that two ways of modifying the argument so as to remove the need for this presupposition fail to preserve the original conclusion. Finally, I argue that, while there are unusual circumstances in which Bostrom’s selective scepticism might be reasonable, we do not currently find ourselves in such circumstances. There is no good reason to uphold the selective scepticism the Simulation Argument presupposes. There is thus no good reason to believe its conclusion. (shrink)
There is widespread debate in contemporary philosophy of mind over the place of conscious experiences in the natural world – where the latter is taken to be broadly as described and explained by such sciences as physics, chemistry and biology; while conscious experiences encompass pains, bodily sensations, perceptions, feelings and moods. Many philosophers and scientists, who endorse physicalism or materialism, maintain that these mental states can be completely described and explained in natural terms. Frank Jackson’s knowledge argument is a (...) very influential objection to physicalism and, thus, to such an optimistic view about the scientific treatability of conscious experiences. According to the knowledge argument, we can know facts about our colour experiences that are not physical facts. At the heart of this book lies a response to the knowledge argument that aims to defend a version of physicalism, that the author calls modest reductionism. This reply is based on the endorsement of the phenomenal concept strategy. According to this response, the knowledge argument cannot prove that there are non-physical facts. Instead, it can only show that there are ways of thinking about colour experiences that are based on phenomenal concepts that differ from scientific concepts. The author argues for the superiority of the phenomenal concept strategy over other influential physicalist replies to the knowledge argument. However, he criticises some recent physicalist accounts of phenomenal concepts and develops his own distinctive theory of these concepts. (shrink)
The Regress Argument is supposed to show that the language of thought hypothesis results in an infinite regress in its explanation of such things as learning, meaning, and understanding. Earlier (in Laurence & Margolis 1997) we argued that the Regress Argument doesn’t work and that even the language of thought’s supporters have given the Regress Argument far too much credit. In this paper, we respond to a critique of our earlier discussion.
Philosophical naturalism is a cluster of views and impulses typically taken to include atheism, physicalism, radical empiricism or naturalized epistemology, and some sort of relativism, subjectivism or nihilism about morality. I argue that a problem arises when the naturalist offers the argument from evil for atheism. Since the argument from evil is a moral argument, it cannot be effectively deployed by anyone who holds the denatured ethical theories that the naturalist typically holds. In the context of these (...) naturalistic ethical theories, the argument from evil typically fails to provide good reason for either the naturalist or the theist to disbelieve in the God of theism. This does not prove that naturalism is false, or that the argument from evil is unsound, but rather that certain naturalists’ use of the argument has been misguided. (shrink)
This article claims that one has to distinguish between X° reflexives which do not bear phi-features, such as number, and XP complex reflexive - which do bear such features. The presence/vs absence of features, it is argued, explains the behavior of so called long distance reflexives - first observed, within the generative tradition, in scandinavian languages - but present all over. The observation according to which XP reflexives are clause bound, while X° reflexives in argument position are not, is (...) some times refered to as "Pica's generalization" (see Burzio (1987) which stressed correctly that is was the first time that such a correlatiion betwen reflexives structure, binding domains, and the role of a cycle was observed. The behavioir of reflexives it is argued derives from the properties of abstratc movement at the level of Logical Form. (shrink)
Let us imagine an ideal ethical agent, i.e., an agent who (i) holds a certain ethical theory, (ii) has all factual knowledge needed for determining which action among those open to her is right and which is wrong, according to her theory, and who (iii) is ideally motivated to really do whatever her ethical theory demands her to do. If we grant that the notions of omniscience and ideal motivation both make sense, we may ask: Could there possibly be an (...) ideal utilitarian, that is, an ideal ethical agent whose ethical theory says that our only moral obligation consists in maximizing utility? I claim that an ideal agent cannot be utilitarian. My reasoning against ideal utilitarianism will parallel Putnam's famous argument against the brains in a vat. Putnam argues that an envatted brain cannot describe its own situation because its words do not refer to brains and vats; I argue that an ideal utilitarian cannot entertain or communicate the beliefs necessary to being a utilitarian.

The Kalām cosmological argument deploys the following causal principle: whatever begins to exist has a cause. Yet, under what conditions does something ‘begin to exist’? What does it mean to say that ‘X begins to exist at t’? William Lane Craig has offered and defended various accounts that seek to establish the necessary and sufficient conditions for when something ‘begins to exist.’ I argue that all of the accounts that William Lane Craig has offered fail on the following grounds: (...) either they entail that God has a cause or they render the Kalām argument unsound. Part of the problem is due to Craig’s view of God’s relationship to time: that God exists timelessly without creation and temporarily with creation. The conclusion is that Craig must abandon either the Kalām argument or his view of God’s relationship to time; he cannot consistently hold both. (shrink)
The expression ‘indispensability argument’ denotes a family of arguments for mathematical realism supported among others by Quine and Putnam.

On the basis of three significant differences between Mark Colyvan’s indispensability arguments and Frege’s applicability argument, I deny that Frege presents an indispensability (...) class='Hi'>argument in that very often quoted section of the Grundegesetze.

This is a reply to a paper by Graham Oppy in the July, 1999 issue of this journal, “Koons’ Cosmological Argument.” Recent work in defeasible or nonmonotonic logic means that the cosmological argument can be cast in such a way that it does not presuppose that every contingent situation, without exception, has a cause. Instead, the burden of proof is shifted to the skeptic, who must produce positive reasons for thinking that the cosmos is an exception to the (...) defeasible law of causality. I show how Oppy’s critique can be turned into a plausible rebuttal of my argument. However, this rebuttal can be set aside when the original argument is supplemented by a plausible account of the nature of causal priority. Several independent lines of argument in support of this account are outlined. (shrink)

In this paper, I shall argue that the small-improvement argument, which is the standard objection to completeness, fails since some of the comparisons involved in the argument might be indeterminate. I shall defend this view from two objections due to Ruth Chang, namely the argument from phenomenology and the argument from perplexity. There are some other objections to the small-improvement argument that also hinge on claims about indeterminacy. John Broome argues that alleged cases of value (...) incomparability are merely examples of indeterminacy in the betterness relation. The main premiss of his argument is the much discussed collapsing principle. I shall offer a new counter-example to this principle and argue that Broome’s defence of the principle is not cogent. On the other hand, Nicolas Espinoza argues that the small-improvement argument fails due to the mere possibility of evaluative indeterminacy. I shall argue that his objection is unsuccessful.

The traditional form of the backward induction argument, which concludes that two initially rational agents would always defect, relies on the assumption that they believe they will be rational in later rounds.

The formulation offered concludes that two initially rational agents would decide to always defect, and relies only on the weaker (...) assumption that they do not believe they will not be rational in later rounds. The argument employs the idea that decisions justify revocable presumptions about behaviour. (shrink)
In this essay I propose an interpretative and explanatory structure for the so-called argumentum ex silento, or argument from silence (henceforth referred to as the AFS). To this end, I explore two examples, namely, Sherlock Holmes’s oft-quoted notice of the “curious incident of the dog in the night-time” from Arthur Conan Doyle’s short story “Silver Blaze,” and the historical question of Paul of Tarsus’s silence on biographical details of the historical Jesus. Through these cases, I conclude that the AFS (...) serves as a dialogical topos best evaluated and understood through the perceived authority of the arguer and the willingness of the audience to accept that authority, due to the “curious” nature of the negative evidence that the argument employed.

In his Perception and Reason, Bill Brewer argues that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs. His argument for this idea relies on a premise according to which in order for the relations with perceptual experience to determine the contents of empirical beliefs, these relations must be reason-giving. He offers an argument for this premise, the so-called Switching Argument. In this paper, I show that the Switching Argument (...) does not work, in which case we have no reason to accept the premise the argument is supposed to establish, and hence no reason to accept Brewer’s argument in favour of the idea that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs.

I present a very general and simple argument—based on the no-signalling theorem—showing that within the framework of the unitary Schrödinger equation it is impossible to reproduce the phenomenological description of quantum mechanical measurements (in particular the collapse of the state of the measured system) by assuming a suitable mixed initial state of the apparatus. The thrust of the argument is thus similar to that of the ‘insolubility theorems’ for the measurement problem of quantum mechanics (which, however, focus on (...) the impossibility of reproducing the macroscopic measurement results). Although I believe this form of the argument is new, I argue it is essentially a variant of Einstein’s reasoning in the context of the EPR paradox—which is thereby illuminated from a new angle.

The product/process distinction with regards to “argument” has a longstanding history and foundational role in argumentation theory.

Is evil evidence against the existence of God? Even if God and evil are compatible, it remains hotly contested whether evil renders belief in God unreasonable. The Evidential Argument from Evil presents five classic statements on this issue by eminent philosophers and theologians and places them in dialogue with eleven original essays reflecting new thinking by these and other scholars. The volume focuses on two versions of the argument. The first affirms that there is no reason for God (...) to permit either certain specific horrors or the variety and profusion of undeserved suffering. The second asserts that pleasure and pain, given their biological role, are better explained by hypotheses other than theism. -/- Contributors include William P. Alston, Paul Draper, Richard M.

Argument-forms exist which are valid over finite but not infinite domains. Despite understanding of this by formal logicians, philosophers can be observed treating as valid arguments which are in fact invalid over infinite domains. In support of this claim I will first present an argument against the classical pragmatist theory of truth by Mark Johnston. Then, more ambitiously, I will suggest the fallacy lurks in certain arguments for physicalism taken for granted by many philosophers today.
Recently, an associative learning account of cognitive control has been suggested (Verguts & Notebaert, 2009). In this so-called adaptation by binding theory, Hebbian learning of stimulus–stimulus and stimulus–response associations is assumed to drive the adaptation of human behavior. In this study, we evaluated the validity of the adaptation-by-binding account for the case of implicit learning of regularities within a stimulus set (i.e., the frequency of specific unit digit combinations in a two-digit number magnitude comparison task) and their association (...) with a particular response. Our data indicated that participants indeed learned these regularities and adapted their behavior accordingly. In particular, influences of cognitive control were even able to override the numerical distance effect—one of the most robust effects in numerical cognition research. Thus, the general cognitive processes involved in two-digit number magnitude comparison seem much more complex than previously assumed. Multi-digit number magnitude comparison may not be automatic and inflexible but influenced by processes of cognitive control being highly adaptive to stimulus set properties and task demands on multiple levels.

Alvin Plantinga has argued that evolutionary naturalism (the idea that God does not tinker with evolution) undermines its own rationality. Natural selection is concerned with survival and reproduction, and false beliefs conjoined with complementary motivational drives could serve the same aims as true beliefs. Thus, argues Plantinga, if we believe we evolved naturally, we should not think our beliefs are, on average, likely to be true, including our beliefs in evolution and naturalism. I argue herein that our cognitive faculties are (...) less reliable than we often take them to be, that it is theism which has difficulty explaining the nature of our cognition, that much of our knowledge is not passed through biological evolution but learned and transferred through culture, and that the unreliability of our cognition helps explain the usefulness of science.

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made (...) intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem. (shrink)
We pose and resolve several vexing decision theoretic puzzles. Some are variants of existing puzzles, such as ‘Trumped’ (Arntzenius and McCarthy 1997), ‘Rouble trouble’ (Arntzenius and Barrett 1999), ‘The airtight Dutch book’ (McGee 1999), and ‘The two envelopes puzzle’ (Broome 1999). Others are new. A unified resolution of the puzzles shows that Dutch book arguments have no force in infinite cases. It thereby provides evidence that reasonable utility functions may be unbounded and that reasonable credence functions need not be countably (...) additive. The resolution also shows that when infinitely many decisions are involved, the difference between making the decisions simultaneously and making them sequentially can be the difference between riches and ruin. Finally, the resolution reveals a new way in which the ability to make binding commitments can save perfectly rational agents from sure losses. (shrink)
If we are going to treat other species so very differently from our own — killing, eating and experimenting on pigs and sheep, for example, but never human beings — then it seems we need to come up with some morally relevant difference between us and them that justifies this difference in treatment.

Laurence BonJour observes that critics of foundationalism tend to argue against it by objecting to "relatively idiosyncratic" versions of it, a strategy which has "proven in the main to be superficial and ultimately ineffective" since answers immune to the objections emerge quickly (1985: 17).

This is a bold strategy from which we can learn even (...) if, in the end, as I shall argue, it fails. (shrink)
John Pollock (1940?2009) was an influential American philosopher who made important contributions to various fields, including epistemology and cognitive science. In the last 25 years of his life, he also contributed to the computational study of defeasible reasoning and practical cognition in artificial intelligence. He developed one of the first formal systems for argumentation-based inference and he put many issues on the research agenda that are still relevant for the argumentation community today. This paper presents an appreciation of Pollock's work (...) on defeasible reasoning and its relevance for the computational study of argument. In our opinion, Pollock deserves to be remembered as one of the founding fathers of the field of computational argument, while, moreover, his work contains important lessons for current research in this field, reminding us of the richness of its object of study.
