  • Circular Reasoning
    Cognitive Science 26 (2002) 767–795 Circular reasoning Lance J. Rips∗ Department of Psychology, Northwestern University, 2029 Sheridan Road, Evanston, IL 60208, USA Received 31 October 2001; received in revised form 2 April 2002; accepted 10 July 2002 Abstract Good informal arguments offer justification for their conclusions. They go wrong if the justifications double back, rendering the arguments circular. Circularity, however, is not necessarily a single property of an argument, but may depend on (a) whether the argument repeats an earlier claim, (b) whether the repetition occurs within the same line of justification, and (c) whether the claim is properly grounded in agreed-upon information. The experiments reported here examine whether people take these factors into account in their judgments of whether arguments are circular and whether they are reasonable. The results suggest that direct judgments of circularity depend heavily on repetition and structural role of claims, but only minimally on grounding. Judgments of reasonableness take repetition and grounding into account, but are relatively insensitive to structural role. © 2002 Cognitive Science Society, Inc. All rights reserved. Keywords: Reasoning; Argumentation 1. Introduction A common criticism directed at informal arguments is that the arguer has engaged in circular reasoning. In one form of this fallacy, the arguer illicitly uses the conclusion itself (or a closely related proposition) as a crucial piece of support, instead of justifying the conclusion on the basis of agreed-upon facts and reasonable inferences. A convincing argument for conclusion c can’t rest on the prior assumption that c, so something has gone seriously wrong with such an argument.

  • Fallacies in Reasoning
    FALLACIES IN REASONING FALLACIES IN REASONING OR WHAT SHOULD I AVOID? The strength of your arguments is determined by the use of reliable evidence, sound reasoning and adaptation to the audience. In the process of argumentation, mistakes sometimes occur. Some are deliberate in order to deceive the audience. That brings us to fallacies. I. Definition: errors in reasoning, appeal, or language use that renders a conclusion invalid. II. Fallacies In Reasoning: A. Hasty Generalization-jumping to conclusions based on too few instances or on atypical instances of particular phenomena. This happens by trying to squeeze too much from an argument than is actually warranted. B. Transfer- extend reasoning beyond what is logically possible. There are three different types of transfer: 1.) Fallacy of composition- occur when a claim asserts that what is true of a part is true of the whole. 2.) Fallacy of division- error from arguing that what is true of the whole will be true of the parts. 3.) Fallacy of refutation- also known as the Straw Man. It occurs when an arguer attempts to direct attention to the successful refutation of an argument that was never raised or to restate a strong argument in a way that makes it appear weaker. Called a Straw Man because it focuses on an issue that is easy to overturn. A form of deception. C. Irrelevant Arguments- (Non Sequiturs) an argument that is irrelevant to the issue or in which the claim does not follow from the proof offered. It does not follow. D. Circular Reasoning- (Begging the Question) supports claims with reasons identical to the claims themselves.

  • The P–T Probability Framework for Semantic Communication, Falsification, Confirmation, and Bayesian Reasoning
    philosophies Article The P–T Probability Framework for Semantic Communication, Falsification, Confirmation, and Bayesian Reasoning Chenguang Lu School of Computer Engineering and Applied Mathematics, Changsha University, Changsha 410003, China; [email protected] Received: 8 July 2020; Accepted: 16 September 2020; Published: 2 October 2020 Abstract: Many researchers want to unify probability and logic by defining logical probability or probabilistic logic reasonably. This paper tries to unify statistics and logic so that we can use both statistical probability and logical probability at the same time. For this purpose, this paper proposes the P–T probability framework, which is assembled with Shannon’s statistical probability framework for communication, Kolmogorov’s probability axioms for logical probability, and Zadeh’s membership functions used as truth functions. Two kinds of probabilities are connected by an extended Bayes’ theorem, with which we can convert a likelihood function and a truth function from one to another. Hence, we can train truth functions (in logic) by sampling distributions (in statistics). This probability framework was developed in the author’s long-term studies on semantic information, statistical learning, and color vision. This paper first proposes the P–T probability framework and explains different probabilities in it by its applications to semantic information theory. Then, this framework and the semantic information methods are applied to statistical learning, statistical mechanics, hypothesis evaluation (including falsification), confirmation, and Bayesian reasoning. Theoretical applications illustrate the reasonability and practicability of this framework. This framework is helpful for interpretable AI. To interpret neural networks, we need further study. Keywords: statistical probability; logical probability; semantic information; rate-distortion; Boltzmann distribution; falsification; verisimilitude; confirmation measure; Raven Paradox; Bayesian reasoning 1.

Research School of Computer Science, Australian National University, Corner of North and Daley Road, Canberra ACT 0200, Australia ? Author to whom correspondence should be addressed; E-Mail: [email protected]. Received: 20 April 2011; in revised form: 24 May 2011 / Accepted: 27 May 2011 / Published: 3 June 2011 Abstract: Understanding inductive reasoning is a problem that has engaged mankind for thousands of years. This problem is relevant to a wide range of fields and is integral to the philosophy of science. It has been tackled by many great minds ranging from philosophers to scientists to mathematicians, and more recently computer scientists. In this article we argue the case for Solomonoff Induction, a formal inductive framework which combines algorithmic information theory with the Bayesian framework. Although it achieves excellent theoretical results and is based on solid philosophical foundations, the requisite technical knowledge necessary for understanding this framework has caused it to remain largely unknown and unappreciated in the wider scientific community. The main contribution of this article is to convey Solomonoff induction and its related concepts in a generally accessible form with the aim of bridging this current technical gap. In the process we examine the major historical contributions that have led to the formulation of Solomonoff Induction as well as criticisms of Solomonoff and induction in general. In particular we examine how Solomonoff induction addresses many issues that have plagued other inductive systems, such as the black ravens paradox and the confirmation problem, and compare this approach with other recent approaches.

  • Hempel and the Paradoxes of Confirmation
    HEMPEL AND THE PARADOXES OF CONFIRMATION Jan Sprenger 1 TOWARDS A LOGIC OF CONFIRMATION The beginning of modern philosophy of science is generally associated with the label of logical empiricism , in particular with the members of the Vienna Circle. Some of them, as Frank, Hahn and Neurath, were themselves scientists, others, as Carnap and Schlick, were philosophers, but deeply impressed by the scientific revolutions at the beginning of the 20th century. All of them were unified in ad- miration for the systematicity and enduring success of science. This affected their philosophical views and led to a sharp break with the “metaphysical” philosophical tradition and to a re-invention of empiricist epistemology with a strong empha- sis on science, our best source of high-level knowledge. Indeed, the members of the Vienna Circle were scientifically trained and used to the scientific method of test and observation. For them, metaphysical claims were neither verifiable nor falsifiable through empirical methods, and therefore neither true nor false, but meaningless. Proper philosophical analysis had to separate senseless (metaphysi- cal) from meaningful (empirical) claims and to investigate our most reliable source of knowledge: science. 1 The latter task included the development of formal frameworks for discovering the logic of scientific method and progress. Rudolf Carnap, who devoted much of his work to this task, was in fact one of the most influential figures of the Vienna Circle. In 1930, Carnap and the Berlin philosopher Hans Reichenbach took over the journal ‘Annalen der Philosophie’ and renamed it ‘Erkenntnis’. Under that name, it became a major publication organ for the works of the logical empiri- cists.

  • List of Paradoxes 1 List of Paradoxes
    List of paradoxes 1 List of paradoxes This is a list of paradoxes, grouped thematically. The grouping is approximate: Paradoxes may fit into more than one category. Because of varying definitions of the term paradox, some of the following are not considered to be paradoxes by everyone. This list collects only those instances that have been termed paradox by at least one source and which have their own article. Although considered paradoxes, some of these are based on fallacious reasoning, or incomplete/faulty analysis. Logic • Barbershop paradox: The supposition that if one of two simultaneous assumptions leads to a contradiction, the other assumption is also disproved leads to paradoxical consequences. • What the Tortoise Said to Achilles "Whatever Logic is good enough to tell me is worth writing down...," also known as Carroll's paradox, not to be confused with the physical paradox of the same name. • Crocodile Dilemma: If a crocodile steals a child and promises its return if the father can correctly guess what the crocodile will do, how should the crocodile respond in the case that the father guesses that the child will not be returned? • Catch-22 (logic): In need of something which can only be had by not being in need of it. • Drinker paradox: In any pub there is a customer such that, if he or she drinks, everybody in the pub drinks. • Paradox of entailment: Inconsistent premises always make an argument valid. • Horse paradox: All horses are the same color. • Lottery paradox: There is one winning ticket in a large lottery. It is reasonable to believe of a particular lottery ticket that it is not the winning ticket, since the probability that it is the winner is so very small, but it is not reasonable to believe that no lottery ticket will win.

    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.

Jaggar I seek to provide a partial answer to this question: what is epistemically required of us as socially situated moral agents? We are familiar with the idea that each of us, as moral agents, has a set of moral obligations—to be kind, to be fair, to do good, or whatever. We are also familiar with the idea that each of us, as epistemic agents, has a set of epistemic obligations—to believe truly, to follow our evidence, to engage in inquiry, or whatever. But moral agents also have epistemic obligations that arise specifically out of the challenge of figuring out what is morally required. I argue that several commonly held accounts of our epistemic obligations as moral agents are seriously flawed; they get the methodological question wrong, perhaps at the expense of the practical question.
