In this paper we show that an essential aspect of solving the problem of uncritical acceptance of expert opinions that is at the root of the ad verecundiam fallacy is the need to disentangle argument from expert opinion from another kind of appeal to authority. Formal and computational argumentation systems enable us to analyze the fault in which an error has occurred by virtue of a failure to meet one or more of the requirements of the (...) argumentation scheme from argument from expert opinion. We present a method for enhancing this capability by showing how arguments from expert opinion are related to, but different from, arguments from deontic authority. (shrink)

Reissuing works originally published between 1937 and 1992, this collection of original texts addresses the philosophical realm of metaphysics, not only ontology but the philosophy of science, religion and morals. The theory of values and the theory of absolutes are the subject of more than one volume, while others take a broader spectrum and outlay the history of the philosophical arguments. The nature of objects and questions of being and identity are addressed from very different perspectives. With some volumes (...) by very eminent thinkers, this is a great addition to any collection on philosophy. (shrink)

A new pragmatic approach, based on the latest developments in argumentation theory, analyzing appeal to expert opinion as a form of argument. Reliance on authority has always been a common recourse in argumentation, perhaps never more so than today in our highly technological society when knowledge has become so specialized—as manifested, for instance, in the frequent appearance of "expert witnesses" in courtrooms. When is an appeal to the opinion of an expert a reasonable type of argument to (...) make, and when does it become a fallacy? This book provides a method for the evaluation of these appeals in everyday argumentation. Specialized domains of knowledge such as science, medicine, law, and government policy have gradually taken over as the basis on which many of our rational decisions are made daily. Consequently, appeal to expert opinion in these areas has become a powerful type of argument. Challenging an argument based on expert scientific opinion, for example, has become as difficult as it once was to question religious authority. Walton stresses that even in cases where expert opinion is divided, the effect of it can still be so powerful that it overwhelms an individual's ability to make a decision based on personal deliberation of what is right or wrong in a given situation. The book identifies the requirements that make an appeal to expert opinion a reasonable or unreasonable argument. Walton's new pragmatic approach analyzes that appeal as a distinctive form of argument, with an accompanying set of appropriate critical questions matching the form. Throughout the book, a historical survey of the key developments in the evolution of the argument from authority, dating from the time of the ancients, is given, and new light is shed on current problems of "junk science" and battles between experts in legal argumentation.

Ordinary arguments from authority have the following structure: A says p; A is authoritative on such things; so p. Legal actors use such arguments whenever they ground their decisions on the sheer “say-so” of legislators, judges, scholars, expert witnesses, and so on. This paper focuses on arguments appealing to the authority of scholars, “doctrinal” or “dogmatic” legal scholars in particular. Appeal to doctrinal authority is a puzzling feature of legal argumentation. In what sense are doctrinal scholars (...) “authorities”? Is p, as advanced by a scholar, descriptive or prescriptive? Is scholarly authority grounded on expertise or something different? The paper addresses these questions. (shrink)

Despite increasing interest in studying arguments from deontic authority of the general form “(1) $$\delta$$ δ is a deontic authority in institution $$\varOmega$$ Ω ; (2) according to $$\delta$$ δ, I should do $$\alpha$$ α, C: therefore, (3) I should do $$\alpha$$ α ”, the state of the art models are not capable of grasping their complexity. The existing sets of critical questions assigned to this argumentation scheme seem to conflate two problems: whether a person is subject (...) to an authority of an institution in the first place and whether the command issued within the context of a particular institution is eventually binding. For this reason, we introduce (1) a set of Basic Critical Questions to scrutinize the former issue, and (2) a set of more detailed questions related to specific features, also referred to as “parameters”, of institutional environments (Intra-Institutional Critical Questions). We identify major elements of institutional environments in which authoritative utterances are made and the crucial parameters of arguments from deontic authority. The selected evidence from the decisions of the Polish Supreme Administrative Court helps us show how these parameters may be used to reconstruct subtypes of this argument scheme, with their associated sets of critical questions. In specific institutional contexts, such detailed schemes are capable of grasping the complexity of appeals to deontic authority and thus should be used rather than general schemes. The reconstruction of argumentation schemes with critical questions shows how particular arguments may successfully be attacked. (shrink)

In this paper, I reply to Seidel’s objections against my argument from expert performance to the effect that arguments from expert opinion are weak arguments. I clarify what Seidel takes to be unclear points in my argument and show that it withstands Seidel’s objections.

Richard Whately’s views of arguments involving authority are very different in his Elements of Rhetoric and his Elements of Logic. This essay begins by documenting these differences and wondering why they are. It then proceeds to take a broader and more historical view of Whately’s discussions of authority and finds him occupying an important developmental ground between his predecessor Locke and contemporary views of the argument from authority. In fact, some of the things we now (...) think are important in a good argument from authority are anticipated by Whately. (shrink)

Herein, I consider arguments resting on an appeal to a non-existent authority as a species of argument from authority, and ultimately show them to be reliant on arguments from analogy in their inferential force. Three sub-types of argument are discussed: from authorities as yet unborn, no longer living, or incapable of ever doing so. In each case it is shown that an element of arguing from analogy is required since there can be (...) no direct evidence of any assertions of the source. In conclusion, it is suggested that such steps of analogy are employed frequently in traditional arguments from authority. (shrink)

In this contribution, I will develop a comprehensive tool for the reconstruction and evaluation of argumentation from expert opinion. This is done by analyzing and then combining two dialectical accounts of this type of argumentation. Walton’s account of the ‘appeal to expert opinion’ provides a number of useful, but fairly unsystematic suggestions for critical questions pertaining to argumentation from expert opinion. The pragma-dialectical account of ‘argumentation from authority’ offers a clear and systematic, but fairly general framework (...) for the reconstruction and evaluation of this type of argumentation. The tool is developed by incorporating Walton’s critical questions into a pragma-dialectical framework. (shrink)

In this paper, I argue that arguments from expert opinion, i.e., inferences from “Expert E says that p” to “p,” where the truth value of p is unknown, are weak arguments. A weak argument is an argument in which the premises, even if true, provide weak support—or no support at all—for the conclusion. Such arguments from expert opinion are weak arguments unless the fact that an expert says that p makes p significantly more likely to (...) be true. However, research on expertise shows that expert opinions are only slightly more accurate than chance and much less accurate than decision procedures. If this is correct, then it follows that arguments from expert opinion are weak arguments. (shrink)

In the 60 years since IRAS was founded, and the 50 years since Zygon: Journal of Religion and Science started, science has developed enormously. More important, though less obvious, the character of religion has changed, at least in Western countries. Church membership has gone down considerably. This is not due to arguments, for example, about science and atheism, but reflects a change in sources of authority. Rather than the traditional and communal authority, an individualism that emphasizes “authenticity” characterizes (...) religion and spirituality in our time. Less extensive but similar is the loss of authority with respect to science. As a consequence, “religion and science” might seek to provide attractive constructive proposals for visions that integrate an ethos and a worldview. IRAS might contribute by providing a platform for information and the exchange of proposals for a particular audience, while Zygon serves a global and diverse audience with well-researched articles.

At the heart of this book is the age-old question of how law and morality are related. The legal positivist, insisting on the separation of the two, explicates the concept of law independently of morality. The author challenges this view, arguing that there are, first, conceptually necessary connections between law and morality and, second, normative reasons for including moral elements in the concept of law. While the conceptual argument alone is too limited to establish a sufficiently strong connection between (...) law and morality, and the normative argument alone fails to address the nature of law, the two arguments together support a nonpositivistic concept of law, toppling legal positivism qua comprehensive theory of law.

A number of authors have developed evidential arguments from evil in the past thirty years. Perhaps the best known evidential arguments from evil are those presented in Rowe (1979) and Draper (1989). We shall spend most of this chapter examining these two arguments.

Polarization is a generalized feature of intellectual life. Few authors however have studied polarities as they actually occur in every day life and discourse. This paper proposes two hypotheses to account for the pervasiveness of polarities. The first relates to uncertainty. Almost everything that touches our lives is filled with irreducible uncertainty. As a rhetoric, polarization uses arguments from (future) consequences in order to manage the future. The second hypothesis relates to phenomenology: body and behavior incorporate tensions or dualistic (...) properties which are easily reproduced in language and thinking. Polarized thinking helps people to imagine extremes so that they may better anticipate the spectrum of possibilities available for action. The article concludes with remarks on the dangers of (over)generalizing and universalizing particulars (or extremes) in polarity based argumentation. (shrink)

The author puts forward and defends a new argument for indirect realism called the argument from pain. The argument is akin to a well-known traditional argument to the same end, the argument from hallucination. Like the latter, it contains one premise stating an analogy between veridical perceptions and certain other states and one premise stating that those states are states of acquaintance with sense-data. The crucial difference is that the states that are said (...) to be analogous to veridical perceptions are pain-states instead of hallucinations. This difference makes the argument from pain immune to the standard objections against the argument from hallucination. (shrink)

There is a familiar argument for the falsity of determinism, an argument that proceeds from the claim that agents are morally responsible. A number of authors have challenged the soundness of this argument. I pose a different challenge, one that grants its soundness. The challenge is that, given certain plausible assumptions, one cannot know the conclusion of this argument on the basis of knowing its premises. That is, one cannot know that determinism is false on (...) the basis of this argument even if agents are in fact morally responsible and moral responsibility is in fact incompatible with determinism. A slightly different version of the challenge tells also against the claim that one can be justified in believing that determinism is false on the basis of the argument, so that the challenge cannot be evaded by a retreat to an epistemic position weaker than knowledge. I compare my challenge to the challenge posed by the external world sceptic, and argue that there are asymmetries between these challenges that make it reasonable to accept the former and reject the latter. I close by considering the prospects for developing an epistemology of moral responsibility that is adequate to answer the challenge. (shrink)

This article explores the relationship between epistemic relativism and Pyrrhonian scepticism. It is argued that a fundamental argument for contemporary epistemic relativism derives from the Pyrrhonian problem of the criterion. Pyrrhonian scepticism is compared and contrasted with Cartesian scepticism about the external world and Humean scepticism about induction. Epistemic relativism is characterized as relativism due to the variation of epistemic norms, and is contrasted with other forms of cognitive relativism, such as truth relativism, conceptual relativism and ontological relativism. (...) An argument from the Pyrrhonian problem of the criterion to epistemic relativism is presented, and is contrasted with three other arguments for epistemic relativism. It is argued that the argument from the criterion is the most fundamental argument for epistemic relativism. Finally, it is noted how the argument of the present paper fits with the author’s previous suggestion that a particularist response to the Pyrrhonian sceptic may be combined with a naturalistic view of epistemic warrant to meet the challenge of epistemic relativism.

Conventionalism about logic is the view that logical principles hold in virtue of some linguistic conventions. According to explicit conventionalism, these conventions have to be stipulated explicitly. Explicit conventionalism is subject to a famous criticism by Quine, who accused it of leading to an infinite regress. In response to the criticism, several authors have suggested reconstructing conventionalism as implicit in our linguistic behaviour. In this paper, drawing on a distinction from proof theory between derivable and admissible rules, I argue (...) that implicit conventionalism has not been stated in a sufficiently precise way, as it leaves open what one needs to say about admissible yet underivable rules. Moreover, it turns out that this challenge cannot be easily met, and that any attempt to meet the challenge makes conventionalism much less attractive a thesis. (shrink)

Critics of the ideal of value‐free science often assume that they must reject the distinction between epistemic and nonepistemic values. I argue that this assumption is mistaken and that the distinction can be used to clarify and defend the argument from inductive risk, which challenges the value‐free ideal. I develop the idea that the characteristic feature of epistemic values is that they promote, either intrinsically or extrinsically, the attainment of truths. This proposal is shown to answer common objections (...) to the distinction and provide a principled basis for separating legitimate from illegitimate influences of nonepistemic values in scientific inference. *Received June 2009; revised September 2009. †To contact the author, please write to: 503 S.

In the paper it is argued that the conceptual resources of Christianity topple the hiddenness argument. According to the author, the variability of the divine love cast doubt on the soundness of Schellenberg’s reasoning. If we understood a perfect love as a maximal and equal concern and identification with all and for all, then a divine love would entail divine impartiality, but because of conflicts of interest between human beings the perfect, divine love cannot be maximal.

In this paper I will argue that there is an inductive and a non-inductive argument from position to know, and will characterise the latter as an argument from authority because of providing content-independent reasons. I will also argue that both types of argument should be doubt-preserving: testimony cannot justify a stronger cognitive attitude in the arguer than the expert herself expresses when she testifies. Failure to appreciate this point undercuts Mizrahi’s claim that arguments (...) class='Hi'>from expert opinion are weak. (shrink)

“NATURAL theology” is generally used as the name of a study which seeks to “get at religious truth” by the use of man's reasoning powers, and not to expound revelation. But I want to limit its application to part of this field. By natural theology I mean here a study which seeks to “get at religious truth” by an empirical examination of things, and not by “pure reason.” It is a “scientific” theology. An example of a natural theologian in this (...) sense would be, I suppose, the author of any one of the Bridgewater Treatises, or Paley, or F. R. Tennant. Perhaps I might have called this kind of theology “empirical theology” ; but I do not want to invent new terms more than I have to. (shrink)

Recent authors, emphasizing Newman’s distaste for natural theology—especially William Paley’s design argument—have urged us to follow Newman’s lead and reject design arguments. But I argue that Newman’s own argument for God’s existence (his argument from conscience) fails without a supplementary design argument or similar reason to think our faculties are truth-oriented. In other words, Newman appears to need the kind of argument he explicitly rejects. Finding Newman’s rejection of natural theology to stem primarily (...) class='Hi'>from factors other than worries about cogency, however, I further argue that there is little reason not to pursue design arguments in order to save the argument from conscience.

Using the profiles of dialogue method we identify a species of ad verecundiam fallacy that works by forestalling of questioning in arguments from expert opinion.

The method is applied to a case of cross-examining a software engineer in a legal deposition in a (...) case of intellectual property litigation. (shrink)

No evidence exists that the accidental origin of life is too improbable to have occurred naturally, but there are numerous attempts to argue so. Dizzying statistics are cited to show that a god had to be responsible.

Describes seven general types of error, with examples. Includes a table (...) of forty-seven statistics used by over twenty authors to date. (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.

Descartes’s proof of the existence of God in the third ’Meditation’ can be interpreted as a version of the argument from design. He cannot point to the marvels of nature, since all he has after the second ’Meditation’ is his ideas, but his idea of God serves as the brilliantly designed entity that he claims he cannot have authored on his own. Several passages in his replies to commentators support this interpretation, and when one considers what Descartes believed (...) he had deduced from this idea, it is understandable that he could consider it a wonderful idea.

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.

Jesper Ahlin Marceta published an article in this journal in which he formulated his “argument from testability”, stating that it is impossible, at least practically, to operationalize procedural authenticity. That is, using procedural accounts of authenticity, one cannot reliably differentiate between authentic and inauthentic desires. There are roughly two ways to respond to the argument from testability: top-down and bottom-up. Several authors have endeavored the top-down approach by trying to show that some conceptions of authenticity might (...) be operationalizable after all. At present, however, the bottom-up approach has not been put to the test. That is, no attempt has been made to use a currently existing assessment tool to guide the development of an account of authenticity. In this paper, I will investigate what it means to develop an account of authenticity bottom-up based on measures of concordance. More specifically, I will investigate the following three research questions. First, how do concordance and authenticity relate at a conceptual level? As crucial similarities exist between these concepts, concordance measures seem to offer a good starting point for the bottom-up approach. Second, how do judgements of concordance differ from judgements of authenticity? Both their scope and the way they are justified will turn out to be different. This suggests novel ways to react to Marceta’s argument from testability. Third, should we develop a theory of concordance? The positive answer to this question will point towards a central limitation of the bottom-up approach. (shrink)

The argument from multiple realization is currently considered the argument against intertheoretic reduction. Both Little and Kincaid have applied the argument to the individualism-holism debate in support of the antireductionist holist position. The author shows that the tenability of the argument, as applied to the individualism-holism debate, hinges on the descriptive constraints imposed on the individualist position. On a plausible formulation of the individualist position, the argument does not establish that the intertheoretic reduction of (...) social theories is highly unlikely. Nonetheless, the reductive project may run into other potential obstacles. For this reason, it is concluded that the prospect of intertheoretic reduction is uncertain rather than unlikely. Key Words: argument from multiple realization • intertheoretic reduction • reductionism • individualism • holism. (shrink)
