Meaning of FALLACY in English
in logic, erroneous reasoning that has the appearance of soundness. Among numerous types of logical fallacies that have been noted, some of the better known are: post hoc ergo propter hoc (after this, therefore, because of this), in which something is assumed to be the cause of something else merely because it was antecedent in time; ad hominem (against the man), attacking an individual rather than establishing pertinent facts; and circulus in probando (arguing in a circle; also called petitio principii, begging the question), attempting to demonstrate a conclusion by means of premises that presuppose that conclusion.
