When confronted with the question of which philosophical conception of religion to consider most adequate, many philosophers appeal to what I call the adequacy-argument: that we should prefer the one that looks most adequate from the perspective of religious believers. In this paper, I provide a critique of the adequacy-argument based on a pragmatic analysis of adequacy-judgments according to which reflective adequacy-judgments are forward-looking, and hence include considerations of the consequences of adopting different judgments (...) as guides for conduct. It is this forward-looking character that is virtually absent within the current adequacy-debate. The major advantage of a pragmatic analysis of adequacy is itself forward-looking: it would enable philosophers of religion to play a more critical and constructive role vis-à-vis religious practices than presently.

In the first part of this paper, two arguments, one by Chomsky, and one by Bar-Hillel and Shamir, are examined in detail and rejected. Both arguments purport to show that the structure of English precludes its having a finite state grammar which correctly enumerates just the well formed sentences of English. In the latter part of the paper I consider the problem of supporting claims about the structure and properties of a natural language when no grammar for the language has (...) yet been accepted.

An institutional Warrant is backed by the rules of some Institution, such as a branch of law or a particular game.

In a priori analogies, the analogue is constructed in imagination, sharing certain properties with the primary subject. The analogue has some further property clearly consequent on those shared properties. Ceteris paribus the primary subject has that property also. The warrant involves non-empirical, e.g., moral intuition but is also defeasible. The argument is thus neither deductive nor inductive, but an additional type. In an inductive analogy, the analogues back the warrant from below. Distinguishing these two types of arguments by analogy (...) gives epistemic evaluative factors primacy over resemblance factors in classifying arguments—a prescient insight on Govier’s part.

Elizabeth Anderson and Debra Satz continue in the tradition of Plato with their work on the role of education in a just society. Both argue that a just society depends on education enabling citizens to realize democratic or civic equality and that this equality depends on sufficiency in the distribution of educational goods. I agree that education is important to preparing democratic citizens, but I disagree about the plausibility of sufficiency here, especially in the educational context. My argument is (...) two‐fold: I first reconsider a generic positional goods objection to educational inequality, I then argue that plausible sufficientarian replies to this objection fail insofar as they are premised on an impoverished conception of class and power that treats all statuses more like socio‐cultural traits when they should instead be referencing the material conditions someone has inside a social structure. One cannot bring an individual X into the halls of power and simultaneously have X represent or compensate those who are presently disadvantaged in the way that X had formerly been disadvantaged. In short, we should worry about the realistic possibility of securing and sustaining a civic‐minded elite because elites have the power and motivation to enrich themselves at the expense of the rest of us. For the sufficientarian story to work, we need more that explains the realistic possibility of a benevolent ruling elite, until then, democratic equality seems to be better realized by aiming for equal educations, adequacy isn't enough.

The ‘death of evidence’ issue in Canada raises the spectre of politicized science, and thus the question of what role social values may have in science and how this meshes with objectivity and evidence. I first criticize philosophical accounts that have to separate different steps of research to restrict the influence of social and other non-epistemic values. A prominent account that social values may play a role even in the context of theory acceptance is the argument from inductive risk. (...) It maintains that the more severe the social consequences of erroneously accepting a theory would be, the more evidence is needed before the theory may be accepted. However, an implication of this position is that increasing evidence makes the impact of social values converge to zero; and I argue for a stronger role for social values. On this position, social values may determine a theory’s conditions of adequacy, which among other things can include co.. (shrink)

In their chapter “Knowledge, Practical Adequacy, and Stakes,” Charity Anderson and John Hawthorne present several challenges to the doctrine of pragmatic encroachment. In this brief reply to their chapter two things are aimed at. First, the chapter argues that there is a sense in which their case against pragmatic encroachment is a bit weaker, and another sense in which that case is much stronger, than Anderson and Hawthorne’s own argument would suggest. Second, the chapter highlights and then builds (...) upon their extremely interesting reflections on one sort of practical matter that has not received proper attention in the literature: the epistemic significance of double-checking. This is done with an eye towards pointing in the direction of further work. (shrink)

Hugh Everett III proposed his relative-state formulation of pure wave mechanics as a solution to the quantum measurement problem. He sought to address the theory’s determinate record and probability problems by showing that, while counterintuitive, pure wave mechanics was nevertheless empirically faithful and hence empirical acceptable. We will consider what Everett meant by empirical faithfulness. The suggestion will be that empirical faithfulness is well understood as a weak variety of empirical adequacy. The thought is that the very idea of (...) empirical adequacy might be renegotiated in the context of a new physical theory given the theory’s other virtues. Everett’s argument for pure wave mechanics provides a concrete example of such a renegotiation. (shrink)

Williamson argues for the contention that substructural logics are ‘ill-suited to acting as background logics for science’. That contention, if true, would be very important, but it is refutable, given what is already known about certain substructural logics. Classical Core Logic is a substructural logic, for it eschews the structural rules of Thinning and Cut and has Reflexivity as its only structural rule. Yet it suffices for classical mathematics, and it furnishes all the proofs and disproofs one needs for the (...) hypothetico-deductive method in science. We explain exactly what Classical Core Logic is, why it is a substructural logic par excellence, and what the basic requirements would be for a logic to be ‘suited to acting as [a] background logic for science’. We also explain how Classical Core Logic meets all these requirements. We end by examining Williamson’s argument in order to expose where its error lies. (shrink)

My main concern in this paper is with Trudy Govier’s acceptability criterion for the adequacy of the premises of an argument considered independently of whether they are “properly connected” to the conclusion. I consider arguments she makes against the view that a good argument must have true premises, and I con-tend that a theory of argument could hold both that for an argument to be a good argument its premises must be true and that (...) for it to be a good argument relative to its audience, the audience must be epistemically justified in accepting its premises as true.

Instrumentalist nominalism responds to the indispensability arguments by rejecting the demand that successful mathematicized scientific theories be nominalized, and instead claiming merely that such theories are nominalistically adequate: the concreta behave ‘as if’ the theory is true. This article examines some definitions of the concept of nominalistic adequacy and concludes with some considerations against instrumentalist nominalism.

In the present paper, I examine how Michael Devitt's proposal as to how to understand the notion of rigidity for general terms fares as regards what I have called the 'criterion of extensional adequacy' for any such notion -namely, the condition according to which any notion of general term rigidity should make the class of rigid terms coincide with that of natural kind terms. I try to show that Devitt's defense of his view from the usual objections raised in (...) the literature fails. In the first place, the proposal seems to overgeneralize, as terms such as 'television set' or 'table', would also be rigid appliers; as I try to show here, the arguments presented by Devitt in order to show that that is not the case are based on some alleged properties of those terms that are also true of some of the expressions he does consider as rigid. In the second place, the proposal also undergeneralizes; even though Devitt himself accepts that this is so, I try to show that his strategy to lessen the disappointment this causes also fails. En este trabajo examino el desempeño de la propuesta acerca de cómo entender la noción de rigidez para términos generales defendida por Michael Devitt respecto de lo que denomino el 'criterio de adecuación extensional' para una noción de rigidez -a saber, la condición según la cual una noción de rigidez para términos generales debería hacer coincidir la clase de términos rígidos con la clase de términos de género natural. Intento mostrar que las estrategias desplegadas por Devitt para defender su postura de las objeciones usuales no son exitosas. En primer lugar, la propuesta parece sobregeneralizar, dado que términos como 'televisor' o 'mesa' también serían aplicadores rígidos; en efecto, según intento defender aquí, los argumentos de Devitt tendientes a mostrar que no lo son se basan en supuestas características de estos términos que son igualmente válidas respecto de las expresiones que él considera rígidas. En segundo lugar, la propuesta también subgeneraliza; si bien Devitt acepta esto, hago notar que su estrategia para quitar dramatismo a este resultado también falla. (shrink)

Internalists about practical reasons maintain that all of an agent’s reasons for action derive their normative force via some relation in which they stand with that agent’s pro-attitudes, or the pro-attitudes that the agent would have in some idealized set of circumstances. One common complaint against internalism is that the view is extensionally inadequate – that it cannot render the correct verdicts about what reasons agents have in a range of important cases. In this paper, I examine that charge of (...) extensional inadequacy, taking as my starting point an argument that Derek Parfit has recently leveled against internalism. Through a close evaluation of that argument and potential replies to it, I attempt to show that internalists cannot accommodate important pre-theoretical intuitions about what reasons we have. However, I also argue that Parfit’s case is importantly overstated; I set out to show that his argument cannot establish, as he thinks it does, that no reasons derive their normative force in the way that internalists believe that all do. In doing so, I draw attention to the possibility of a hybrid position about practical reasons that, surprisingly, receives little attention in the existing literature. If the arguments of the paper succeed, I will have established a modest theoretical advantage for hybridism over internalism – namely, that it is not vulnerable to the charge of extensional inadequacy. My hope is that this goes some way toward establishing hybridism’s credentials as a serious alternative to its “pure” competitors. (shrink)

In this paper I question the claim that the increasingly popular position known as ‘free-will theism’ or ‘the open view of God’ supports a rich religious life. To do this I advance a notion of ‘religious adequacy’, and then argue that free-will theism fails to be religiously adequate with respect to one of the principal practices of the religious life – petitionary prayer. Drawing on current work in libertarian free-will theory, I consider what are likely the only two lines (...) of defence free-will theists might use in response to my argument. I argue that these defences either fail or have features that make them unacceptable to free-will theists. I then suggest that this failure with petitionary prayer is an instance of a larger problem for free-will theism, that the position's distinctive views often differ more dramatically from the common beliefs and practices of most believers than is usually recognized or acknowledged. I conclude that free-will theism can support a rich religious life only for those who make the requisite changes in belief and practice, including changing their expectations about petitionary prayer.

The aim of the presented article is to provide an in-depth analysis of the adequacy of designating Penrose as a complex Pythagorean in view of his much more common designation as a Platonist. Firstly, the original doctrine of the Pythagoreans will be briefly surveyed with the special emphasis on the relation between the doctrine of this school and the teachings of the late Platonic School as well as its further modifications. These modifications serve as the prototype of the contemporary (...) claims of the mathematicity of the Universe. Secondly, two lines of Penrose’s arguments in support of his unique position on the ontology of the mathematical structures will be presented: their existence independent of the physical world in the atemporal Platonic realm of pure mathematics and the mathematical structures as the patterns governing the workings of the physical Universe. In the third step, a separate line of arguments will be surveyed that Penrose advances in support of the thesis that the complex numbers seem to suit these patterns with exceptional adequacy. Finally, the appropriateness of designation Penrose as a complex Pythagorean will be assessed with the special emphasis on the suddle threshold between his unique position and that of the adherents of the mathematicity of the Universe.

All definitions of mental disorder are backed up by arguments that rely on general criteria (e.g., that a definition should be consistent with ordinary language). These desiderata are rarely explicitly stated, and there has been no systematic discussion of how different definitions should be assessed. To arrive at a well-founded list of desiderata, we need to know the purpose of a definition. I argue that this purpose must be practical; it should, for example, help us determine who is entitled to (...) publicly funded health care. I then propose eight conditions of adequacy that can be used to assess competing definitions (e.g., the ordinary language condition, the coherence condition, and the condition of normative adequacy). These conditions pull in different directions, however, and we must decide which are most important. I also suggest that there is no single definition that can help us deal with all the relevant practical issues. (shrink)

The aim of the paper is to develop general criteria of argumentative validity and adequacy for probabilistic arguments on the basis of the epistemological approach to argumentation. In this approach, as in most other approaches to argumentation, proabilistic arguments have been neglected somewhat. Nonetheless, criteria for several special types of probabilistic arguments have been developed, in particular by Richard Feldman and Christoph Lumer. In the first part (sects. 2-5) the epistemological basis of probabilistic arguments is discussed. With regard to (...) the philosophical interpretation of probabilities a new subjectivist, epistemic interpretation is proposed, which identifies probabilities with tendencies of evidence (sect. 2). After drawing the conclusions of this interpretation with respect to the syntactic features of the probability concept, e.g. one variable referring to the data base (sect. 3), the justification of basic probabilities (priors) by judgements of relative frequency (sect. 4) and the justification of derivative probabilities by means of the probability calculus are explained (sect. 5). The core of the paper is the definition of '(argumentatively) valid derivative probabilistic arguments', which provides exact conditions for epistemically good probabilistic arguments, together with conditions for the adequate use of such arguments for the aim of rationally convincing an addressee (sect. 6). Finally, some measures for improving the applicability of probabilistic reasoning are proposed (sect. 7). (shrink)

It is a common complaint that antireductionist arguments are primarily negative. Here I describe an alternative nonreductionist epistemology based on considerations taken from multidisciplinary research in biology. The core of this framework consists in seeing investigation as coordinated around sets of problems (problem agendas) that have associated criteria of explanatory adequacy. These ideas are developed in a case study, the explanation of evolutionary innovations and novelties, which demonstrates the applicability and fruitfulness of this nonreductionist epistemological perspective. This account also (...) bears on questions of conceptual change and theory structure in philosophy of science. †To contact the author, please write to: Department of Philosophy, University of Minnesota, 831 Heller Hall, 271 19th Ave. S., Minneapolis, MN 55455; e‐mail: [email protected].

Although I have little sympathy for Nagel's instrumentalism, his "dictum" on the debates over scientific realism (as Boyd refers to it) is disconcertingly accurate; it does seem as if "the already long controversy...can be prolonged indefinitely." The reason for this, however, is not that realists and instrumentalists are divided by merely terminological differences in their "preferred mode[s] of speech", indeed, this analysis appeals only if you are already convinced that realism of any robust sort is mistaken. The debates persist, instead, (...) because the most sophisticated positions on either side now incorporate self-justifying conceptions of the aim of philosophy and of the standards of adequacy appropriate for judging philosophical theories of science. Realism and anti realism thus confront one another as preferred and essentially incommensurable modes of philosophical practice; it is in this sense that they have "dialectical resources for maintaining [their positions] in face of [virtually any] criticism." In what follows I first give an analysis of the central forms of argument for realism and anti realist responses to them that shows how the locus of debate has shifted to metaphilosophical issues. This is the basis for characterizing and assessing the forms of philosophical practice that are now emerging; my thesis is that there are strong grounds for preferring realism if the competing positions are judged as comprehensive research programs.

The debate on probabilistic measures of coherence flourishes for about 15 years now. Initiated by papers that have been published around the turn of the millennium, many different proposals have since then been put forward. This contribution is partly devoted to a reassessment of extant coherence measures. Focusing on a small number of reasonable adequacy constraints I show that (i) there can be no coherence measure that satisfies all constraints, and that (ii) subsets of these adequacy constraints motivate (...) two different classes of coherence measures. These classes do not coincide with the common distinction between coherence as mutual support and coherence as relative set-theoretic overlap. Finally, I put forward arguments to the effect that for each such class of coherence measures there is an outstanding measure that outperforms all other extant proposals. One of these measures has recently been put forward in the literature, while the other one is based on a novel probabilistic measure of confirmation. (shrink)

Pascal‘s wager is expounded as a paradigm case of a practical,decision-theoretical argument for acting as if a proposition is true when wehave no theoretical reasons to accept or reject it (1.1.–1.2.). Thoughthe paradigm is fallacious in various respects there are valid and adequatearguments for acting as if certain propositions are true: that theoreticalentities exist, that there are material perceptual objects, that the worldis uniform across time (1.3). After this analysis of examples the author‘sgeneral approach for developing criteria for the (...) validity and adequacy oftypes of argument (2.1.) is applied: Having discussed some problems(2.2.–2.3.), a general epistemic principle for such ’pascal arguments‘is developed, which characterizes their premisses and, if introduced as anadditional premiss, can make them deductively valid (2.4).

This paper discusses the epistemological and methodological bases of a scientific theory of meaning and proposes a detailed version of a formal theory of argumentation based on Anscombre and Ducrot's conception. Argumentation is shown to be a concept which is not exclusively pragmatic, as it is usually believed, but has an important semantic body. The bridge between the semantic and pragmatic aspects of argumentation consists in a set of gradual inference rules, called topoi, on which the argumentative movement is based. (...) The content of each topos is determined at the pragmatic level, while the constraints on the forms of the topoi attached to a sentence are determined at the semantic level. Applications and possible applications toartificial intelligence and to cognitive sciences are discussed. In particular, the gradual models used to account for argumentation are shown to be extremely promising for Knowledge management, a discipline which includes knowledge acquisition, knowledge representation, transmission of knowledge (communication, interfaces, etc.), knowledge production (decision help, reasoning, etc.). A first formal model is presented and discussed: it is shown in details how it accounts for most of the argumentative features of sentences containing but, little and a little, and how it can be extended to describe sentences containing other argumentative connectives. However, this model is shown to be too simple and to violate the compositionality principle, which is shown, in the first section, to bean important methodological principle for any scientific theory. After a detailed analysis of the possible reasons for this violation, an improved model is proposed and its adequacy is discussed. (shrink)

The central thesis of this book is that the argument that probability is insufficient to handle uncertainty in artificial intelligence (AI) is metaphysical in nature. Piscopo calls this argument against probability the non-adequacy claim and provides this summary of it [which first appeared in (Piscopo and Birattari 2008)]:Probability theory is not suitable to handle uncertainty in AI because it has been developed to deal with intrinsically stochastic phenomena, while in AI, uncertainty has an epistemic nature. (Piscopo (3))Piscopo (...) uses the term “metaphysical” in the Popperian sense: the non-adequacy claim is metaphysical (rather than scientific) since it cannot be disproved (much less established) by observation or experiment.In Chapter 2, Piscopo recounts some of the relevant history and issues in philosophy of science. There is little that is controversial here. One problem is that when addressing the question of how a particular probabilistic model is tested, Piscopo limits herself .. (shrink)

I. The argument from design or ‘teleological argument’ purports to be an inductive proof for the existence of God, proceeding from the evidence of the order exhibited by natural phenomena to the probable conclusion of a rational agent responsible for producing that order. The argument was severely criticized by David Hume in his Dialogues Concerning Natural Religion , and it was widely conceded that Hume's objections had cast serious doubt on the adequacy of the teleological (...) class='Hi'>argument, if not destroyed its credibility entirely. However, there has been a recent reappraisal of this claim by R. G. Swinburne, who maintains that none of Hume's criticisms have any validity against a ‘carefully articulated version of the argument’. Using an analogical argument based on temporal regularities rather than on spatial regularities , Swinburne claims to have shown that the teleological argument is a legitimate inference to the best explanation whose force depends only on the strength of the analogy and on the degree to which the resulting theory makes explanation of empirical matters simpler and more coherent. Moreover, he claims to have shown that the argument provides support for the Christian monotheistic hypothesis and not merely for the weak claim that the universe was designed . This is an important claim since it has long been thought that Hume's most devastating blow was dealt when he showed that the teleological argument provides just as much support for the negation of certain propositions considered essential to Christian monotheism as it does for their affirmation.

Trust is often perceived as having great value. For example, there is a strong belief that trust will bring different sorts of public goods and help us preserve common resources. A related concept which is just as important, but perhaps not explicitly discussed to the same extent as “trust”, is “reliance” or “confidence”. To be able to rely on some agent is often seen as a prerequisite for being able to trust this agent. Up to now, the conceptual discussion about (...) the definition of trust and reliance has been rational in the sense that most people involved have offered arguments for their respective views, or against competing views. While these arguments rely on some criterion or other, these criteria are rarely explicitly stated, and to our knowledge, no systematic account of such criteria has been offered. In this paper we give an account of what criteria we should use to assess tentative definitions of “trust” and “reliance”. We will also offer our own well-founded definitions of “trust” and “reliance”. Trust should be regarded as a kind of reliance and we defend what we call “the accountability view” of trust, by appealing to the desiderata we identify in the first parts of the paper. (shrink)

There is currently a significant amount of interest in understanding and developing theories of realization. Naturally arguments have arisen about the adequacy of some theories over others. Many of these arguments have a point. But some can be resolved by seeing that the theories of realization in question are not genuine competitors because they fall under different conceptual traditions with different but compatible goals. I will first describe three different conceptual traditions of realization that are implicated by the arguments (...) under discussion. I will then examine the arguments, from an older complaint by Norman Malcolm against a familiar functional theory to a recent argument by Thomas Polger against an assortment of theories that traffic in inherited causal powers, showing how they can be resolved by situating the theories under their respective conceptual traditions.

The aim of this paper is to defend the claim that arguments are truth-directed, and to discuss the role that truth plays in the evaluation of arguments that are truth-directed. It concludes that the proper place of truth is in the metatheory in terms of which a theory of evaluation is to be worked out, rather than in the theory of evaluation itself as a constraint on premise adequacy.

The miracle argument for scientific realism can be cast in two forms: according to the miraculous theory argument, realism is the only position which does not make the empirical successes of particular theories miraculous. According to the miraculous choice argument, realism is the only position which does not render the fact that empirically successful theories have been chosen a miracle. A vast literature discusses the miraculous theory argument, but the miraculous choice argument has been unjustifiably (...) neglected. I raise two objections to Richard Boyd's defense of the latter: (1) we have no miracle free account of the emergence of take-off theories and (2) the anti-realist can account for the non-miraculous choice of empirically successful theories by attributing mere empirical adequacy to background theory. I argue that the availability of extra-empirical criteria that are arguably truth conductive but not theory-laden suffices to answer (1), and the unavailability of extra-empirical criteria that are conductive to empirical adequacy but not necessarily to truth (and are also not theory-laden) constitutes to reply to (2). The prospects for a realist victory are at least somewhat promising, on a controversial assumption about the rate at which empirically successful theories emerge. (shrink)

According to dispositionalism about modality, a proposition <p> is possible just in case something has, or some things have, a power or disposition for its truth; and <p> is necessary just in case nothing has a power for its falsity. But are there enough powers to go around? In Yates (2015) I argued that in the case of mathematical truths such as <2+2=4>, nothing has the power to bring about their falsity or their truth, which means they come out both (...) necessary and not possible. Combining this with axiom (T), it is easy to derive a contradiction. I suggested that dispositionalists ought to retreat a little and say that <p> is possible just in case either p, or there is a power to bring it about that p, grounding the possibility of mathematical propositions in their truth rather than in powers. Vetter’s (2015) has the resources to provide a response to my argument, and in her (2018) she explicitly addresses it by arguing for a plenitude of powers, based on the idea that dispositions come in degrees, with necessary properties a limiting case of dispositionality. On this view there is a power for <2+2=4>, without there being a power to bring about its truth. In this paper I argue that Vetter’s case for plenitude does not work. However, I suggest, if we are prepared to accept metaphysical causation, a case can be made that there is indeed a power for <2+2=4>. (shrink)

Is truth a condition of premise adequacy? We may distinguish objective and subjective argument correctness. Objective correctness means true premises rendering the conclusion true or probable. Subjective correctness means acceptable pr emises rendering the conclusion acceptable. Acceptability depends on evidence available and so is internalist. Objective and subjective correctness of the premises is ordinarily distinct. For connection adequacy, objective rightness and subjective righ tness coincide. We recognize entailment or rendering probably a priori. Logic is thus internalist. Logic (...) needs an internalist notion of acceptability for premise evaluation to fall within its purview, although it need not deny the objective sens e of rightness. (shrink)

Contributing to the recent debate on whether or not explanations ought to be differentiated from arguments, this article argues that the distinction matters to science education. I articulate the distinction in terms of explanations and arguments having to meet different standards of adequacy. Standards of explanatory adequacy are important because they correspond to what counts as a good explanation in a science classroom, whereas a focus on evidence-based argumentation can obscure such standards of what makes an explanation explanatory. (...) I provide further reasons for the relevance of not conflating explanations with arguments (and having standards of explanatory adequacy in view). First, what guides the adoption of the particular standards of explanatory adequacy that are relevant in a scientific case is the explanatory aim pursued in this context. Apart from explanatory aims being an important aspect of the nature of science, including explanatory aims in classroom instruction also promotes students seeing explanations as more than facts, and engages them in developing explanations as responses to interesting explanatory problems. Second, it is of relevance to science curricula that science aims at intervening in natural processes, not only for technological applications, but also as part of experimental discovery. Not any argument enables intervention in nature, as successful intervention specifically presupposes causal explanations. Students can fruitfully explore in the classroom how an explanatory account suggests different options for intervention. (shrink)

Causal representations are distinguished from non-causal ones by their ability to predict the results of interventions. This widely-accepted view suggests the following adequacy condition for causal models: a causal model is adequate only if it does not contain variables regarding which it makes systematically false predictions about the results of interventions. Here I argue that this condition should be rejected. For a class of equilibrium systems, there will be two incompatible causal models depending on whether one intervenes upon a (...) certain variable to fix its value, or ‘lets go’ of the variable and allows it to vary. The latter model will fail to predict the result of interventions on the let-go-of variable. I argue that there is no basis for preferring one of these models to the other, and thus that models failing to predict interventions on particular variables can be just as adequate as those making no such false predictions. This undermines a key argument (Dash in Caveats for causal reasoning with equilibrium models. University of Pittsburgh. PhD thesis, 2003) against relying upon causal models inferred from equilibrium data. (shrink)

Foundationalist theories of justification for science were undermined by the theory-ladeness thesis, which has affinities with coherentist epistemologies. A challenge for defenders of coherentist theories of scientific justification is to specify coherence relations relevant to science and to show how these relations make the truth of their bearers likely. Coherence relations include characteristics that pick out better explanations in the implementation of abductive arguments. Empiricist philosophers have attacked abductive reasoning by claiming that explanatory virtues are pragmatic, having no implications regarding (...) truth. However, empiricist's basic beliefs are subject to the same challenges facing abduction, both of which can be met by citing causally coherent etiologies, which are commonplace in biological explanations, and by demonstrating the relevance of causal coherence to truth.

History is replete with false and unfulfilled promises, but also with singular acts of courage, resilience, and ingenuity.

According to the Principle of Conditional Non-Contradiction (CNC), conditionals of the form “If p, q” and “If p, not q” cannot both be true, unless p is inconsistent. This principle is widely regarded as an adequacy constraint on any semantics that attributes truth conditions to conditionals. Gibbard has presented an example of a pair of conditionals that, in the context he describes, appear to violate CNC. He concluded from this that conditionals lack truth conditions. We argue that this conclusion (...) is rash by proposing a new diagnosis of what is going on in Gibbard’s argument. We also provide empirical evidence in support of our proposal. (shrink)

_Physics_ VIII 1 presents a multi-stage argument concluding that there was not, nor ever will be, a time when there was not nor will not be motion (_Phys_. VIII 1.252b5-6).

My claim will be that _Physics_ VIII 1 is apodeictically conditioned – its structure must be understood in terms of the theory of science in the _Posterior Analytics_ and the methods for establishing principles (...) in the _Topics. Physics_ VIII 1 is not demonstrative in a straightforward deductive way, but is structured with the nature of a scientific _genos_ and requirements for scientific knowledge always in mind. Aristotle begins by asking about the eternality of motion, posing a pair of conceptual opposites that form a mutually exclusive and logically exhaustive dichotomy. But the initial statement of the dichotomy turns out to require substantial unpacking, leading eventually to a single remaining option, that motion in the cosmos is eternal. But the status of this conclusion itself turns out to be problematic. Put in terms of Aristotle’s theory of science, all _phusiologoi_ made motion a posit or hypothesis, whether they regarded motion as eternal or not. Though Aristotle has rejected one option, at a deeper level, he finds all previous accounts lacking. Because motion is fundamental to all coming-to-beand-passing-away, what is at stake is the status and adequacy of a principle governing the whole science of nature (_tên theôrian pasan_; 250b17). In this way, the chapter prepares for the subsequent investigation into the principles of cosmic motion. (shrink)

Various claims have been made, recently, that Darwin's argumentation in the Origin instantiates and so supports some general philosophical proposal about scientific theorizing, for example, the "semantic view". But these claims are grounded in various incorrect analyses of that argumentation. A summary is given here of an analysis defended at greater length in several papers by the present author. The historical and philosophical advantages of this analysis are explained briefly. Darwin's argument comprises three distinct evidential cases on behalf of (...) natural selection, cases, that is, for its existence, its adequacy and its responsibility. Theorizing, today, about evolution by natural selection involves a similar structure of evidential and explanatory concerns. (shrink)

We investigate the philosophical significance of the existence of different semantic systems with respect to which a given deductive system is sound and complete. Our case study will be Corcoran's deductive system D for Aristotelian syllogistic and some of the different semantic systems for syllogistic that have been proposed in the literature. We shall prove that they are not equivalent, in spite of D being sound and complete with respect to each of them. Beyond the specific case of syllogistic, the (...) goal is to offer a general discussion of the relations between informal notions—in this case, an informal notion of deductive validity—and logical apparatuses such as deductive systems and (model-theoretic or other) semantic systems that aim at offering technical, formal accounts of informal notions. Specifically, we will be interested in Kreisel's famous 'squeezing argument'; we shall ask ourselves what a plurality of semantic systems (understood as classes of mathematical structures) may entail for the cogency of specific applications of the squeezing argument. More generally, the analysis brings to the fore the need for criteria of adequacy for semantic systems based on mathematical structures. Without such criteria, the idea that the gap between informal and technical accounts of validity can be bridged is put under pressure. (shrink)

This paper presents a new argument for the likelihood ratio measure of confirmation by showing that one of the adequacy criteria used in another argument can be replaced by a more plausible and better supported criterion which is a special case of the weak likelihood principle. This new argument is also used to show that the likelihood ratio measure is to be preferred to a measure that has recently received support in the literature.

Our typology is based on two ground adequacy factors, one logical and one epistemic. Logically, the step from premises to conclusion may be conclusive or only ceteris paribus. Epistemically, warrants may be backed a priori or a posteriori. Hence there are four types of arguments: conclusive a priori, defeasible a priori, defeasible a posteriori, and prima facie conclusive a posteriori. We shall give an example of each and compare our scheme with other typologies.

In this article, I consider a number of arguments that assume that beings who have immortal souls occupy a special position in the sphere of moral concern. First, I place these arguments in their historical and cultural contexts. Next, I formulate several conditions of adequacy that all such arguments must satisfy. Subsequently, I distinguish two different general kinds of such arguments: Inclusionary arguments attempt to use the immortality of soul as a criterion for either including someone into a sphere (...) of morality while excluding others or, at least, for elevating someone's position within this sphere. Modifying arguments attempt to strengthen or weaken moral considerations that already apply to a being included into the sphere of morality. I argue that, although some modifying arguments may fulfill all conditions of adequacy, they have very little practical importance. (shrink)

I discuss Aristotle’s opening argument against Platonic Forms in _Metaphysics_ A.9, ‘the Razor’, which criticizes the introduction of Forms on the basis of an analogy with a hypothetical case of counting things. I argue for a new interpretation of this argument, and show that it involves two interesting objections against the introduction of Forms as formal causes: one concerns the completeness and the other the adequacy of such an explanatory project.

Abstract: The article presents and critically discusses Walton's (and Reed's and Macagno's) argument scheme approach to a theory of good argumentation. In particular, four characteristics of Walton's approach are presented: 1. It presents normative requirements for argumentation in the form of argument schemes, i.e. relatively concrete type descriptions. 2. These schemata are enthymematic, i.e. they omit some of the premises required by other approaches. 3. The actual argument schemes are usually supplemented by critical questions. 4. The method (...) is inductive, bottom-up, gaining the normative schemata by abstraction from empirically collected groups of similar arguments. These characteristics, among others, are then discussed on the basis of four adequacy conditions: AC1: effectiveness in achieving the epistemic goal of obtaining and communicating justified acceptable opinions; AC2: completeness in capturing the good argument types; AC3: efficiency in achieving the goals; AC4: justification of the argument schemes. The discussion then reveals a number of weaknesses in Walton's argument schemes; among other things, they are neither effective (in the defined sense) nor truly justified. Contributing factors to these problems include the schema approach, i.e. not looking at the form of arguments, and the lack of epistemological foundations in the development of good types of arguments. However, the critical analyses reveal a better alternative: an epistemological approach based on epistemological principles. The article concludes with a detailed analysis of the scheme Practical Inference, which confirms the general criticism in detail. (shrink)

This paper responds to Kauffeld’s 2009 OSSA paper, considering the adequacy of his “commitment-based” approach to “ordinary presumptive practices” to sup-ply an account of presumption fit for general application in normative theories of argument. The central issue here is whether socially-grounded presumptions are defeasible in the right sorts of ways so as to pro-duce “truth-tropic” presumptive inferences.

Part I argues that ontological arguments, like other classical proofs of the existence of God, are parts of larger arguments in which they are embedded. These larger arguments include reasons supporting the proofs’ premises and responses to them, and to the proofs’ claims to validity and non-circularity, since, in the final analysis, our assessment of the proofs will express our best judgment of the cumulative force of all the considerations bearing on their overall adequacy. Part II illustrates these points (...) by examining contemporary defences of, and attacks on, one of the ontological argument’s central premises, namely, that God’s existence is logically possible.

Resumen Este artículo analiza, en discusión con Joaquín García-Huidobro y Alejandro Miranda, la conveniencia de utilizar en moral sexual el argumento de la facultad pervertida, conforme al cual sería inmoral frustrar el fin natural de las facultades reproductivas. Según García-Huidobro y Miranda este argumento sólo puede utilizarse desde el “principio de totalidad”, pues su uso aislado llevaría a los absurdos denunciados por la New Natural Law Theory. Con vistas a una reconsideración de este argumento, se demuestra la importancia de considerar (...) la ética en su carácter tópico o contextual. Así, es en el ámbito de la templanza y de las inclinaciones sexuales donde el AFP cobra un papel normativo; en cambio, el “principio de totalidad” entra en juego cuando se está considerando el problema del límite de las intervenciones médicas.This paper focuses on the adequacy of using the so-called perverted faculty argument within the context of sexual morality. According to this argument, frustrating the reproductive faculty would be immoral. Professors García-Huidobro and Miranda think that this argument can be appropriately used only within the framework of the principle of totality. They argue that an unqualified use of the PFA would lead to the absurdities pointed out by the New Natural Law Theory. In order to see the PFA in a new light we demonstrate the importance of respecting the dialectical or contextual nature of Ethics. Thus, regarding temperance, and especially sexual inclinations, the PFA has a clear normative role. The principle of totality, instead, must be used when considering the problem of the moral limits of medical interventions. (shrink)
