# Topic: Affirming the consequent

 Logical Fallacy: Affirming the Consequent Affirming the Consequent is a non-validating form of argument in propositional logic; for instance, let "p" be false and "q" be true, then there is no inconsistency in supposing that the first, conditional premiss is true, which makes the premisses true and the conclusion false. So, in general, in an instance of the form Affirming the Consequent, if it is reasonable to consider the converse of the conditional premiss to be a suppressed premiss, then the argument is not fallacious, but a valid enthymeme. Thus, the Counter-Example is a fallacious instance of Affirming the Consequent. www.fallacyfiles.org /afthecon.html   (266 words)

 Affirming the consequent - Wikipedia, the free encyclopedia Affirming the consequent is a logical fallacy in the form of a hypothetical proposition. The fallacy of affirming the consequent occurs when a hypothetical proposition comprising an antecedent and a consequent asserts that the truthhood of the consequent implies the truthhood of the antecedent. If P, then Q. Therefore, P. This logical error is called the fallacy of affirming the consequent because it is mistakenly concluded from the second premise that the affirmation of the consequent entails the truthhood of the antecedent. en.wikipedia.org /wiki/Affirming_the_consequent   (229 words)

 RELATIVITY: THE MADNESS OF 20th CENTURY SCIENCE The process of deification is advancing, mathematicians willingly help him and he does not need to use the outrageous principle of maximum absurdity in the deduction of Lorentz transforms (although he fiercely continues to use this principle in other cases). If a proposition (consequent) follows from another proposition (antecedent), we can affirm the antecedent (as an axiom) and deduce the consequent.

 lifeissues.net | A Brief Introduction to Logic Logicians simply took the first two vowels of Affirmo (I affirm), the A and the I, as well as the first two vowels of Nego, the E and the O, and employed them as codes for these kinds of statements. The A statement is called the universal affirmative, and it takes the form: All S (subject) is P (predicate), for example: All giraffes are animals. However, affirming the consequent (AC) and denying the antecedent (DA) are invalid forms of reasoning. www.lifeissues.net /writers/mcm/ph/ph_01philosophyyouth8.html   (2403 words)

 Fallacies [Internet Encyclopedia of Philosophy] If you have enough evidence to affirm the consequent of a conditional and then suppose that as a result you have sufficient reason for affirming the antecedent, you commit the fallacy of affirming the consequent. A conditional is an if-then statement; the if-part is the antecedent, and the then-part is the consequent. So, she committed the murder." This deductively invalid argument commits the fallacy of affirming the consequent, but it isn't a non sequitur because it has significant inductive strength. www.iep.utm.edu /f/fallacy.htm   (13726 words)

 Ephilosopher :: Logic and Formal Reasoning :: modus ponens or affirming the consequent   (Site not responding. Last check: ) In fact, because it is a tautology, that seems to militate for it's being classified as a (perhaps degenerate) case of modus ponens, and not affirming the consequent. Your original #3 is an exclusive case in which affirming the consequent could be considered valid reasoning. Using this new definition of the affirming the consequent fallacy, argument form #3 would be classified as an affirming the consequent fallacy and would therefore be invalid. www.ephilosopher.com /phpBB_14-action-viewtopic-topic-66-start-0.html   (1989 words)

 The fallacy of racial profiling But it would be "affirming the consequent" to conclude that someone who is a woman is therefore pregnant. Likewise, if criminal justice statistics suggest that criminals are likely to be fl or Latino, it would be affirming the consequent to conclude that fls and Latinos are likely to be criminals.

 Affirming the Consequent Affirming the Consequent is a formal fallacy, meaning that unlike some other fallacies you have seen, the problem with this reasoning has to do with the form or pattern of the argument itself.

 Deduction and Induction If we were to affirm that the premises are true but deny that the conclusion is true, we would be violating the principle of contradiction; we would be affirming and denying the same thing in the same respect at the same time. If we affirm that the premises are true but deny that the conclusion is true, we would not be violating the principle of contradiction since the premises do not require us to affirm that the conclusion is true under penalty of contradicting ourselves if we do otherwise. In fact, the structure of the fallacious argument in deductive logic, the Fallacy of Affirming the Consequent, is at the heart of scientific method. falcon.jmu.edu /~omearawm/deduction.html   (1204 words)

 Conditional Reasoning You can affirm or deny either the antecedent or consequent, which may lead to error. Denying the consequent means going backwards, saying 'If B is false, then A must also be false.' Thus if you say 'If it is raining, I will get wet', then the trap is to assume that if I am not getting wet then it is not raining. The 7 could deny the consequent and hence must be checked. changingminds.org /explanations/decision/conditional_reasoning.htm   (415 words)

 Formal Fallacies   (Site not responding. Last check: ) Most of the arguments that a classical logician would label Affirming the Consequent are really Retroductions in which the causal principle to which the argument appeals is not the best explanation for the observation being explained. The argument follows the pattern labeled Affirming the Consequent, and this argument is undeniably fallacious. However, it is fallacious because it is an Arcane Explanation (appealing to the agency of entities not generally believed to exist), not because it affirms its consequent. www.cuyamaca.net /bruce.thompson/Fallacies/formalfallacies.asp   (476 words)

 MISSION: CRITICAL (Review Exercises) Valid: affirming the antecedent of a chain argument. Even so, the second premise, "You don't do your homework," affirms the consequent (Q), and so the argument is invalid.

 Truth Tables for compound statements and arguments This means that we can an argument in the form of a conditional statement which has as the antacedent the conjunction of the premises (of the argument) and which has as the consequent the conclusion of the argument. Notice that in the final row of the truth table for Modus Ponens, the truth value of the conditional is always true (a tautology if it were a statement), while in the final row of the truth table for Affirming the Consequent, there is one row where the conditional is false. This row represents the combination of truth and falsity of the simple statements which makes it possible for the conjunction of the premises to be true, and the conclusion false. www.mcckc.edu /longview/ctac/ttable2.htm   (695 words)

 Argument from Design... Affirming the Consequent? - IIDB Ok, so the fallacy of affirming the consequent is a result of a misue of the material conditional p -> q.

 Philosophical Dictionary: Aesthetics-Altruism The formal fallacy committed in a categorical syllogism that violates a syllogistic rule by having an affirmative conclusion derived from at least one negative proposition as a premise. The first affirms that every spaniel also belongs to the class of dogs, while the latter affirms that there is at least one member commonly included among both children and people who play word games. The differential roles to which individuals are assigned in a society, he argued, are clearly signified not only by the presence of particular notions in its cultural paradigms, but even more dramatically by the absence of others. www.philosophypages.com /dy/a2.htm   (1575 words)
