Argumentation and Fallacies in Creationist Writings Against Evolutionary Theory Petteri Nieminen1,2* and Anne-Mari Mustonen1
Nieminen and Mustonen Evolution: Education and Outreach 2014, 7:11 http://www.evolution-outreach.com/content/7/1/11 RESEARCH ARTICLE Open Access Argumentation and fallacies in creationist writings against evolutionary theory Petteri Nieminen1,2* and Anne-Mari Mustonen1 Abstract Background: The creationist–evolutionist conflict is perhaps the most significant example of a debate about a well-supported scientific theory not readily accepted by the public. Methods: We analyzed creationist texts according to type (young earth creationism, old earth creationism or intelligent design) and context (with or without discussion of “scientific” data). Results: The analysis revealed numerous fallacies including the direct ad hominem—portraying evolutionists as racists, unreliable or gullible—and the indirect ad hominem, where evolutionists are accused of breaking the rules of debate that they themselves have dictated. Poisoning the well fallacy stated that evolutionists would not consider supernatural explanations in any situation due to their pre-existing refusal of theism. Appeals to consequences and guilt by association linked evolutionary theory to atrocities, and slippery slopes to abortion, euthanasia and genocide. False dilemmas, hasty generalizations and straw man fallacies were also common. The prevalence of these fallacies was equal in young earth creationism and intelligent design/old earth creationism. The direct and indirect ad hominem were also prevalent in pro-evolutionary texts. Conclusions: While the fallacious arguments are irrelevant when discussing evolutionary theory from the scientific point of view, they can be effective for the reception of creationist claims, especially if the audience has biases. Thus, the recognition of these fallacies and their dismissal as irrelevant should be accompanied by attempts to avoid counter-fallacies and by the recognition of the context, in which the fallacies are presented. -

Western Logic - Formal & Informal Fallacy: Types of 6 Fallacies (Philosophy) Fallacy When an argument fails to support its conclusion, that argument is termed as fallacious in nature. A fallacious argument is hence an erroneous argument. In other words, any error or mistake in an argument leads to a fallacy. So, the definition of fallacy is any argument which although seems correct but has an error committed in its reasoning. Hence, a fallacy is an error; a fallacious argument is an argument which has erroneous reasoning. In the words of Frege, the analytical philosopher, “it is a logician՚s task to identify the pitfalls in language.” Hence, logicians are concerned with the task of identifying fallacious arguments in logic which are also called as incorrect or invalid arguments. There are numerous fallacies but they are classified under two main heads; Formal Fallacies Informal Fallacies Formal Fallacies Formal fallacies are those mistakes or errors which occur in the form of the argument. In other words, formal fallacies concern themselves with the form or the structure of the argument. Formal fallacies are present when there is a structural error in a deductive argument. It is important to note that formal fallacies always occur in a deductive argument. There are of six types; Fallacy of four terms: A valid syllogism must contain three terms, each of which should be used in the same sense throughout; else it is a fallacy of four terms. -

CHAPTER XXX. Of Fallacies. Section 827. After examining the conditions on which correct thoughts depend, it is expedient to classify some of the most familiar forms of error. It is by the treatment of the Fallacies that logic chiefly vindicates its claim to be considered a practical rather than a speculative science. To explain and give a name to fallacies is like setting up so many sign-posts on the various turns which it is possible to take off the road of truth. Section 828. By a fallacy is meant a piece of reasoning which appears to establish a conclusion without really doing so. The term applies both to the legitimate deduction of a conclusion from false premisses and to the illegitimate deduction of a conclusion from any premisses. There are errors incidental to conception and judgement, which might well be brought under the name; but the fallacies with which we shall concern ourselves are confined to errors connected with inference. Section 829. When any inference leads to a false conclusion, the error may have arisen either in the thought itself or in the signs by which the thought is conveyed. The main sources of fallacy then are confined to two-- (1) thought, (2) language. Section 830. This is the basis of Aristotle's division of fallacies, which has not yet been superseded. Fallacies, according to him, are either in the language or outside of it. Outside of language there is no source of error but thought. For things themselves do not deceive us, but error arises owing to a misinterpretation of things by the mind. -
Proving Propositional Tautologies in a Natural Dialogue
Fundamenta Informaticae xxx (2013) 1–16 1 DOI 10.3233/FI-2013-xx IOS Press Proving Propositional Tautologies in a Natural Dialogue Olena Yaskorska Institute of Philosophy and Sociology, Polish Academy of Sciences, Warsaw, Poland Katarzyna Budzynska Institute of Philosophy and Sociology, Polish Academy of Sciences, Warsaw, Poland Magdalena Kacprzak Department of Computer Science, Bialystok University of Technology, Bialystok, Poland Abstract. The paper proposes a dialogue system LND which brings together and unifies two tradi- tions in studying dialogue as a game: the dialogical logic introduced by Lorenzen; and persuasion dialogue games as specified by Prakken. The first approach allows the representation of formal di- alogues in which the validity of argument is the topic discussed. The second tradition has focused on natural dialogues examining, e.g., informal fallacies typical in real-life communication. Our goal is to unite these two approaches in order to allow communicating agents to benefit from the advan- tages of both, i.e., to equip them with the ability not only to persuade each other about facts, but also to prove that a formula used in an argument is a classical propositional tautology. To this end, we propose a new description of the dialogical logic which meets the requirements of Prakken’s generic specification for natural dialogues, and we introduce rules allowing to embed a formal dialogue in a natural one. We also show the correspondence result between the original and the new version of the dialogical logic, i.e., we show that a winning strategy for a proponent in the original version of the dialogical logic means a winning strategy for a proponent in the new version, and conversely. -

334 CHAPTER 7 INFORMAL FALLACIES a Deductive Fallacy Is
CHAPTER 7 INFORMAL FALLACIES A deductive fallacy is committed whenever it is suggested that the truth of the conclusion of an argument necessarily follows from the truth of the premises given, when in fact that conclusion does not necessarily follow from those premises. An inductive fallacy is committed whenever it is suggested that the truth of the conclusion of an argument is made more probable by its relationship with the premises of the argument, when in fact it is not. We will cover two kinds of fallacies: formal fallacies and informal fallacies. An argument commits a formal fallacy if it has an invalid argument form. An argument commits an informal fallacy when it has a valid argument form but derives from unacceptable premises. A. Fallacies with Invalid Argument Forms Consider the following arguments: (1) All Europeans are racist because most Europeans believe that Africans are inferior to Europeans and all people who believe that Africans are inferior to Europeans are racist. (2) Since no dogs are cats and no cats are rats, it follows that no dogs are rats. (3) If today is Thursday, then I'm a monkey's uncle. But, today is not Thursday. Therefore, I'm not a monkey's uncle. (4) Some rich people are not elitist because some elitists are not rich. 334 These arguments have the following argument forms: (1) Some X are Y All Y are Z All X are Z. (2) No X are Y No Y are Z No X are Z (3) If P then Q not-P not-Q (4) Some E are not R Some R are not E Each of these argument forms is deductively invalid, and any actual argument with such a form would be fallacious. -

Steve Miller and Cherie K. Miller Brilliant People Believe Nonsense [because]... They Fall for Common Fallacies The dull mind, once arriving at an inference that flatters the desire, is rarely able to retain the impression that the notion from which the inference started was purely problematic. ― George Eliot, in Silas Marner In the last chapter we discussed passages where bright individuals with PhDs violated common fallacies. Even the brightest among us fall for them. As a result, we should be ever vigilant to keep our critical guard up, looking for fallacious reasoning in lectures, reading, viewing, and especially in our own writing. None of us are immune to falling for fallacies. -

I am grateful to Prof. Alkalay-Gut for her insightful, inspiring yet challenging comments and questions, time and again forcing me to pause and rethink the relationship between the literary aspects of my research and psychoanalysis. I am grateful to both my supervisors for enabling me to explore a unique, newly blazed path to literary form, and rediscover thus late seventeenth-century drama. I wish to express my gratitude to Prof. Ruth Ronen for allowing me the use of the manuscript of her book Aesthetics of Anxiety before it was published.

Fallacy and argumentational vice ANDREW ABERDEIN Department of Humanities and Communication Florida Institute of Technology 150 West University Boulevard, Melbourne Florida 32901-6975, U.S.A. [email protected] ABSTRACT: If good argument is virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument. Rather, if the normativity of good argumentation is explicable in terms of virtues, we should expect the wrongness of fallacies to be explicable in terms of vices. This approach is defended through case studies of several fallacies, with particular emphasis on the ad hominem. KEYWORDS: ad hominem, argumentational vice, argumentational virtue, fallacy, virtue argumentation 1. A VIRTUE THEORY OF ARGUMENTATION Several authors have recently begun to apply virtue theory to argumentation (for example, Cohen, 2009; Aberdein, 2010; Correia, 2012). This paper explores how this approach copes with the analysis and appraisal of fallacies. -
Inductive Arguments: Fallacies ID1050– Quantitative & Qualitative Reasoning Analyzing an Inductive Argument
Inductive Arguments: Fallacies ID1050– Quantitative & Qualitative Reasoning Analyzing an Inductive Argument • In an inductive argument, the conclusion follows from its premises with some likelihood. • Inductive arguments can be strong, weak, or somewhere between. • Ways to attack an inductive argument: • Introduce additional (contradictory) premises that weaken the argument. • Question the accuracy of the supporting premises. • Identify one (or more) logical fallacies in the argument. What is a Fallacy? • A logical fallacy is an error in reasoning in an argument. • Formal fallacy • A ‘formal fallacy’ is an error in the structure of an argument. • Formal fallacies are used to analyze deductive arguments for validity by means of symbolic logic. • Informal fallacy • An ‘informal fallacy’ is an error in the content of an argument. • This is the type of fallacy that will be discussed in this presentation. • An argument with a fallacy is said to be ‘fallacious’. Formal and Informal Fallacies • Formal fallacy example: • All humans are mammals. All dogs are mammals. So, all humans are dogs. • This argument has a structural flaw. The premises are true, but they do not logically lead to the conclusion. This would be uncovered by the use of symbolic logic. • Informal fallacy example: • All feathers are light. Light is not dark. So, all feathers are not dark. • The structure of this argument is actually correct. The error is in the content (different meanings of the word ‘light’.) It uses a fallacy called ‘Equivocation’. Lists of Fallacies • There are a great number of identified fallacies of the informal type. Following are some good websites that list them and provide definitions and examples.
