Argument is a term sometimes used as synonymous with the subject of a discourse, but more frequently appropriated to any kind of method employed for the purpose of confuting or at least silencing an opponent. Logicians have reduced arguments to a number of distinct heads, such as the argumentum ad judicium, which founds on solid proofs and addresses to the judgment; the argumentum ad verecundiam, which appeals to the modesty or bashfulness of an opponent by reminding him of the great names or authorities by whom the view disputed by him is supported; the argumentum ad ignorantiam, the employment of some logical fallacy towards persons likely to be deceived by it; and the argumentum ad hominem, an argument which presses a man with consequences drawn from his own principles and concessions, or his own conduct.
