10. Argument in the Alternative

Originating in the legal profession, argument in the alternative is a strategy in which a lawyer advances several competing (and possibly mutually exclusive) arguments in order to pre-empt objections by his adversary, with the goal of showing that regardless of interpretation there is no reasonable conclusion other than the advocate's.

Bart Simpson's classic "I didn't do it, no one saw me do it, you can't prove anything!" could be considered a somewhat humorous example. In a more serious example, a lawyer might argue, not only that his client was elsewhere when a murder or other crime took place, but also that even if he had been on the scene, he would have had no way of accessing the alleged murder weapon. In this way, the lawyer attacks several premises of the prosecution's argument at once. The secondary line of reasoning might be presented to persuade a sub-audience who would not otherwise agree with the primary argument.
