unreferenced date December 2008 A fallacy of necessity fellacia necessitas is a logical fallacyfallacy in the logic of a syllogism whereby a degree of unwarranted necessity is placed in the conclusion. Example a Bachelors are necessarily unmarried. b John is a bachelor. Therefore, c John cannot marry. The condition a appears to be a Tautology rhetoric tautology and therefore true. The condition b is a statement of fact about John which makes him subject to a that is, b declares John a bachelor, and a states that all bachelors are unmarried. Because c presumes b will always be the case, it is a fallacy of necessity. John, of course, is always free to stop being a bachelor, simply by getting married if he does so, b is no longer true and thus not subject to the tautology logic tautology a . In this case, c has unwarranted necessity by assuming, incorrectly, that John cannot stop being a bachelor. Formally speaking, this type of argument equivocates between the De dicto and de re Context of modality de dicto necessity of a and the De dicto and de re Context of modality de re necessity of c . The argument is only valid if both a and c are construed de re . This, however, would undermine the argument, as a is only a tautology de dicto indeed, interpreted de re , it is false.

An informal fallacy is an Logical argument argument whose stated premises fail to support their proposed conclusion. ref Kelly, D. 1994 The Art of Reasoning . W W Norton & Company, Inc. ISBN 0 393 96466 3 ref The deviation in an informal fallacy often stems from a flaw in the path of reason ing that links the premises to the conclusion. In contrast to a formal fallacy , the error has to do with issues of inference ratiocination manifest in natural language language used to state the propositions the range of elements that can be symbolized by language is broader than that which the symbolism of Mathematical logic formal logic can represent. Deductive and inductive informal fallacies Informal fallacies of deductive reasoning contain a fundamental disconnect between the premises and the conclusion that renders the argument validity invalid . This disconnect often stems from the presence of a hidden co premise that, if presented, would validate the argument. Inductive reasoning Inductive informal fallacies are slightly different from their deductive counterparts, as their merit rests in the Statistical inference inductive strength of the premise conclusion link rather than in the presence of hidden premises. For instance, the fallacy of hasty generalization , can be roughly stated as A is an X A is also a Y Therefore, all X s are also Y s If the populations X and Y are both too large to sample completely, then the statement is inductive. In such a case, a hasty generalization occurs when the number of X s and Y s is insufficient to represent the respective populations. It is important ..., D. Epstein, R. L. Kernberger, C.

refimprove date September 2011 The logical fallacy of accident also called destroying the exception or a dicto simpliciter ad dictum secundum quid is a deductive reasoning deductive fallacy occurring in statistical syllogisms an argument based on a generalization when an exception to a rule of thumb ref http fallacyfiles.org accident.html ref is ignored. It is one of the thirteen fallacies originally identified by Aristotle . The fallacy occurs when one attempts to apply a general rule to an irrelevant situation. For instance Cutting people with a knife is a crime. Surgeons cut people with knives. Surgeons are criminals. It is easy to construct fallacious arguments by applying general statements to specific incidents that are obviously exceptions. Generalizations that are weak generally have more exceptions the number of exceptions to the generalization need not be a minority of cases and vice versa. This fallacy may occur when we confuse generalizations some for categorical statement s always and everywhere . It may be encouraged when no qualifier qualifying words like some , many , rarely etc. are used to mark the generalization. For example Germans are Nazism Nazis The premise above could be used in an argument concluding that all Germans or current Germans should be held responsible for the actions of the Nazis. Qualifying the major term first term Some Germans are Nazis This premise may make it more obvious that it is making an extremely weak generalization and not a categorical rule. Related Inductive reasoning inductive fallacies include overwhelming exception , hasty generalization . See faulty generalization . The opposing kind of dicto simpliciter fallacy is the converse accident .

Merge to Masked man fallacy date April 2011 Orphan date February 2009 In philosophical logic , the intensional fallacy is committed when one makes an illicit use of Leibniz s law in an argument. Leibniz s law states that, if one object has a certain property, while another object does not have the same property, the two objects cannot be identical. For example, if Clark Kent can fly, and Lois Lane cannot fly, they must be different people. The intensional fallacy occurs when this argument is used with properties that are Extensional context intensional , that is, when the property depends on the description of the object used. In this case, although the object may have a given property under one description, and not have that property under a different description, they may nonetheless be the same object. An example of the intensional fallacy would be Lois Lane believes that Superman can fly. Lois Lane does not believe that Clark Kent can fly. Therefore Superman and Clark Kent are not the same person. The conclusion in this case is false, because what Lois Lane believes depends not on the actual object Clark Kent Superman , but rather on the name used. Intensional sentences are extensionally opaque. These sentences are often intentional with a t , that is they involve a property of the mind that is directed at an object. I can coherently hold at the same time I believe that Muhammed Ali was the heavyweight champion and I don t believe that Cassius Clay was heavyweight champion if I don t know that Muhammed Ali and Cassius Clay were the same person. In my belief, Muhhamed Ali and Cassius Clay fail in their extension. This fallacy was cited by authors Jerry Fodor and Massimo Piattelli Palmarini in their book What Darwin Got Wrong . ref http www.salon.com books feature 2010 02 22 what darwin got wrong jerry fodor ref This fallacy is also known as the epistemic fallacy.

distinguish Historical fallacy The historian s fallacy is a logical fallacy that occurs when one assumes that decision makers of the past viewed events from the same perspective and having the same information as those subsequently analyzing the decision. It is not to be confused with Presentism literary and historical analysis presentism , a mode of historical analysis in which present day ideas such as moral standards are projected into the past. The fallacy was outlined in 1970 by David Hackett Fischer , who suggested it was analogous to William James s psychologist s fallacy . Fischer did not suggest that historians should refrain from retrospective analysis in their work, but he reminded historians that their subjects were not able to see into the future. As an example, he cited the well known argument that Japan s surprise attack on Pearl Harbor should have been predictable in the United States because of the many indications that an attack was imminent. What this argument overlooks, says Fischer, citing the work of Roberta Wohlstetter , is that there were innumerable conflicting signs which suggested possibilities other than an attack on Pearl Harbor. Only in retrospect do the warning signs seem obvious signs which pointed in other directions tend to be forgotten. See also hindsight bias . In the field of military history , historians sometimes use what is known as the fog of war technique in hopes of avoiding the historian s fallacy. In this approach, the actions and decisions of the historical subject such as a military commander are evaluated primarily on the basis of what that person knew at the time, and not on future developments that the person could not have known. According to Fischer, this technique was pioneered by the American historian Douglas Southall Freeman in his influential biographies of Robert E. Lee and George Washington .

The genetic fallacy is a ignoratio elenchi fallacy of irrelevance where a conclusion is suggested based solely on something or someone s origin rather than its current meaning or context. This overlooks any difference to be found in the present situation, typically transferring the positive or negative esteem from the earlier context.

The first criterion of a good argument is that the premises must have bearing on the truth or falsity of the claim in question. ref Attacking Faulty Reasoning A Practical Guide to Fallacy Free Arguments Third Edition by T.

The fallacy of composition arises when one infers that something is true of the whole from the fact that it is true of some part of the whole or even of every proper part . For example This fragment of metal cannot be broken with a hammer, therefore the machine of which it is a part cannot be broken with a hammer. This is clearly fallacious, because many machines can be broken into their constituent parts without any of those parts being breakable. This fallacy is often confused with the fallacy of hasty generalization , in which an unwarranted inference is made from a statement about a sample to a statement about the population from which it is drawn.

Refimprove date July 2010 The regression or regressive fallacy is an informal fallacy . It ascribes cause where none exists. The flaw is failing to account for natural fluctuations. It is frequently a special kind of the post hoc fallacy . Explanation Things like stock market prices, golf scores, the earth s temperature, and chronic back pain fluctuate naturally and usually regression toward the mean regress towards the mean . The logical flaw is to make predictions that expect exceptional results to continue as if they were average see Representativeness heuristic . People are most likely to take action when variance is at its peak. Then after results become more normal they believe that their action was the cause of the change when in fact it was not causal. This use of the word regression was coined by Sir Francis Galton in a study from 1885 called Regression Toward Mediocrity in Hereditary Stature . He showed that the height of children from very short or very tall parents would move towards the average. In fact, in any situation where two variables are less than perfectly correlated, an exceptional score on one variable may not be matched by an equally exceptional score on the other variable. The imperfect correlation between parents and children height is not entirely heritable means that the distribution of heights of their children will be centered somewhere between the average of the parents and the average of the population as whole.
