Critical Thinking, Requirement 3 What is a fallacy? (minimum 100 words) A fallacy is a part of an argument that is either flawed in logic or form, and the flaw is bad enough to invalidate an argument in its entirety. Fallacies are generally classified by their source (how they are related or used in the argument), in particular material, verbal, and logical fallacies. They can also be classed as "formal" or "informal", indicating that it has taken an invalid form (formal) or that the flaw is not in the form, but in the reasoning itself (informal). Often, fallacies can attack something unrelated to the argument, as in ad homminim attacks that seek to discredit the speaker, rather than his or her argument.
