There Is No Fallacy of Arguing from Authority
There is no Fallacy ofArguing from Authority EDWIN COLEMAN University ofMelbourne Keywords: fallacy, argument, authority, speech act. Abstract: I argue that there is no fallacy of argument from authority. I first show the weakness of the case for there being such a fallacy: text-book presentations are confused, alleged examples are not genuinely exemplary, reasons given for its alleged fallaciousness are not convincing. Then I analyse arguing from authority as a complex speech act. R~iecting the popular but unjustified category of the "part-time fallacy", I show that bad arguments which appeal to authority are defective through breach of some felicity condition on argument as a speech act, not through employing a bad principle of inference. 1. Introduction/Summary There's never been a satisfactory theory of fallacy, as Hamblin pointed out in his book of 1970, in what is still the least unsatisfactory discussion. Things have not much improved in the last 25 years, despite fallacies getting more attention as interest in informal logic has grown. We still lack good answers to simple questions like what is a fallacy?, what fallacies are there? and how should we classifY fallacies? The idea that argument from authority (argumentum ad verecundiam) is a fallacy, is well-established in logical tradition. I argue that it is no such thing. The second main part of the paper is negative: I show the weakness of the case made in the literature for there being such a fallacy as argument from authority. First, text-book presentation of the fallacy is confused, second, the examples given are not genuinely exemplary and third, reasons given for its alleged fallaciousness are not convincing. -

Beck Physics 496 Introduction to Research Lecture 2.0: Tools for the Scientific Skeptic (Lance Cooper, Laura Greene, Tony Liss, Doug Beck) Critical Evaluation Scientific papers and research presentations, when well done, are very convincing. How do you know if they are correct? How do you know if your own research is correct? Answer: Apply logic. Critique the arguments made to arrive at the conclusions. “Science is simply common-sense at its best; that is, rigidly accurate in observation and merciless to fallacy in logic.“ (The Crayfish, 1880). “Darwin’s Bulldog” Thomas Henry Huxley, biologist 1825-1895 Copyright © 2014 Board of Directors of the University of Illinois 1 PHYS 496, Spring 2014 02/14/2014 D.H. Beck Aside: Oxford Evolution Debate Held at the Oxford University Museum seven months after the 1859 publication of The Origin of Species. Bishop Samuel Wilberforce to Huxley: “On which side do you claim your descent from a monkey, your grandmother or your grandfather?” Huxley: “I would not be ashamed to be descended from a monkey. But I would be ashamed to be descended from a man who uses his great gifts to obscure the truth!” The Scientific Method 1. Observe and describe a phenomenon or group of phenomena. 2. Formulate an hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation. 3. Use the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations. 4. Perform experimental tests of the predictions. -

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. -

Critical Thinking, Common Fallacies, and Leadership
Critical Thinking, Common Fallacies, and Leadership Judge Hal Campbell, Ph.D. One of my all-time favorite movies was Tom Clancy’s, Hunt for Red October. Within that movie there is a scene that I found fascinating within my capacity as a university professor teaching logic and statistics. The scene involves a meeting of top level decision makers who are gathered around a table in the basement of the Whitehouse, and after a briefing given by Jack Ryan pertaining to the design, construction, and launch of a new Russian submarine, the National Security Advisor who is chairing the meeting asks Admiral Greer (the character played by James Earl Jones) what conclusions he has made. The Admiral responded, “Sir, the data support no conclusions as of yet”. I thought this statement was one of the more profound expressions that I had ever heard in any movie. What an astonishing and refreshing response I thought to myself. He was exactly right that it was premature, given the limited information available at the time, to base any decision about the Russian’s intent, mission, or objectives. The data simply didn’t support any conclusion, yet there at the conference table, sat a gaggle of top-level executives who were actively engage in supposition and speculation resulting in the fabrication all sorts of boogie-men, end of day’s scenarios, and rationale for a first strike option that needed to be recommended to the President. As I have pointed out in previous articles, critical thinking, logic, and reasoning are not taught as a separate academic discipline within our K-12 school system. -
Checking Your Arguments: 2
Checking Your Arguments: 2 The kind of logic that is used in constructing an essay is not dependent on specialized learning or some esoteric technique. It is the kind of logic that normal people use every day in making decisions and in trying to persuade other people to share their opinions. But every word of a written argument is generally scrutinized very carefully by its readers, so special care is needed to keep logical fallacies from ruining the argument. By getting into the habit of searching the first draft of your papers for logical fallacies, you can not only improve your writing but also refine the logic that you use in everyday discussions and decisions. Here is a check-list of some of the logical "fallacies" (or mistakes) that even good writers may easily fall into. The use of logical fallacies often results in faulty conclusions; it can lead people into terrible difficulties, not just in writing, but in making real-life decisions. A fallacy may, however, appear in an argument for a perfectly correct idea; it may, in that case, discredit even that correct idea--but it will certainly discredit the author. Suppose, for instance, that someone argued that roses, like human beings, are living things, that there is a similarity between plants and people, and that, therefore, because all plants eventually die, we can expect that all people will eventually die, too. Now, it's perfectly true that all people will die; the problem is that the argument that is used to prove this (an argument by analogy) is so fallacious that it could never, in itself, establish the fact of human mortality. -

The Ad Hominem Fallacy
Critical Thinking – Handout 3 – The Ad Hominem Fallacy Testimony is like an arrow shot from a long bow; the force of it depends on the strength of the hand that draws it. Argument is like an arrow from a cross-bow, which is equal force though shot by a child. –Samuel Johnson, A Life At this point, we have several fundamental critical thinking skills (CTSs) at our disposal: CTS #1: the ability to identify passages of text and determine whether or not they are arguments, CTS #2: the ability to determine whether an argument is valid/invalid and strong/weak by using the imagination test. CTS #3: the ability to specify the exact conclusion of the argument. CTS#4: the ability to identify which premises (reasons) are relevant and which are irrelevant to a specific conclusion. CTS#5: the ability to determine how different premises relate to each other in their support of the conclusion (diagramming). The next set of CTSs will focus more on the evaluation of different arguments. CTS#6: the ability to identify different fallacies as they occur in everyday arguments and distinguish these fallacies from similar-looking but non-fallacious arguments. 1. AD HOMINEM ARGUMENTS & AD HOMINEM FALLACIES A fallacy is an error in reasoning. We say that someone’s reasoning or argument is “fallacious” when they argue incorrectly from the premises to the conclusion. A large portion of critical thinking has to do with the description, investigation, and taxonomy of different fallacies. One important kind of fallacy is the ad hominem1 fallacy. To get clear on what an ad hominem fallacy is, we first need to define what an “ad hominem statement” and “ad hominem argument” is: An ad hominem statement is any (positive, negative, or neutral) statement made about an individual.
