  1. That's like asking how many dishes are there in culinary cuisine. Humans will never die (assumed), therefore logic will never die, therefore we will never find the final logical fallacy until people stop using false logic.

    According to wikipedia's list of logical fallacies there are 31 formal fallacies, 34 informal fallacies, 11 faulty generalizations, and 23 red herring fallacies. So in total there are 99 fallacies according to common consensus from the good folks at wikipedia. I hope you read all of this because I took the time to look it up, copy and paste, reformat and delete the pesky "[edit}s" strewn throughout.

    Formal Fallacies

    Formal fallacies are arguments that are fallacious due to an error in their form or technical structure. All formal fallacies are specific types of non sequiturs.

    Appeal to probability: because something could happen, it is inevitable that it will happen. This is the premise on which Murphy's Law is based.

    Argument from fallacy: if an argument for some conclusion is fallacious, then the conclusion must necessarily be false.

    Bare assertion fallacy: premise in an argument is assumed to be true purely because it says that it is true.

    Base rate fallacy: using weak evidence to make a probability judgment without taking into account known empirical statistics about the probability.

    Conjunction fallacy: assumption that specific conditions are more probable than a single general one.

    Correlative based fallacies

    Denying the correlative: where attempts are made at introducing alternatives where there are none

    Suppressed correlative: where a correlative is redefined so that one alternative is made impossible

    Fallacy of necessity: a degree of unwarranted necessity is placed in the conclusion based on the necessity of one or more of its premises

    False dilemma (false dichotomy): where two alternative statements are held to be the only possible options, when in reality there are several

    If-by-whiskey: An answer that takes side of the questioner's suggestive question

    Ignoratio elenchi (irrelevant conclusion or irrelevant thesis)

    Homunculus fallacy: where a "middle-man" is used for explanation, this usually leads to regressive middle-man explanations without actually explaining the real nature of a function or a process

    Masked man fallacy: the substitution of identical designators in a true statement can lead to a false one

    Naturalistic fallacy: a fallacy that claims that if something is natural, then it is "good" or "right"

    Nirvana fallacy: when solutions to problems are said not to be right because they are not perfect

    Negative Proof fallacy: that, because a premise cannot be proven false, the premise must be true; or that, because a premise cannot be proven true, the premise must be false

    Package-deal fallacy: when two or more things have been linked together by tradition or culture are said to stay that way forever

    Propositional fallacies (Formal):

    Affirming a disjunct: concluded that one logical disjunction must be false because the other disjunct is true.

    Affirming the consequent: the antecedent in an indicative conditional is claimed to be true because the consequent is true. Has the form if A, then B; B, therefore A

    Denying the antecedent: the consequent in an indicative conditional is claimed to be false because the antecedent is false; if A, then B; not A, therefore not B

    Quantificational fallacies (Formal):

    Existential fallacy: an argument has two universal premises and a particular conclusion, but the premises do not establish the truth of the conclusion

    Illicit conversion: the invalid conclusion that because a statement is true, the inverse must be as well

    Proof by example: where things are proved by giving an example

    Formal syllogistic fallacies

    Syllogistic fallacies are logical fallacies that occur in syllogisms.

    Affirmative conclusion from a negative premise

    Fallacy of exclusive premises: a categorical syllogism that is invalid because both of its premises are negative

    Fallacy of four terms: a categorical syllogism has four terms

    Illicit major: a categorical syllogism that is invalid because its major term is undistributed in the major premise but distributed in the conclusion

    Illicit minor: a categorical syllogism that is invalid because its minor term is undistributed in the minor premise but distributed in the conclusion.

    Fallacy of the undistributed middle: the middle term in a categorical syllogism is not distributed

    Categorical syllogism: an argument with a positive conclusion, but one or two negative premises :

    Informal fallacies

    Informal fallacies are arguments that are fallacious for reasons other than structural ("formal") flaws.

    Argument from repetition (argumentum ad nauseam)

    Appeal to ridicule: a specific type of appeal to emotion where an argument is made by presenting the opponent's argument in a way that makes it appear ridiculous

    Argument from ignorance ("appeal to ignorance"): The fallacy of assuming that something is true/false because it has not been proven false/true. For example: "The student has failed to prove that he didn't cheat on the test, therefore he must have cheated on the test."
