Debate is contention in argument; dispute, controversy; discussion; esp. the discussion of questions of public interest in Parliament or in any assembly. Debate is a method of interactive and representational argument. Debate is a broader form of argument than deductive reasoning, which only examines whether a conclusion is a consequence of premisses, and factual argument, which only examines what is or isn’t the case, or rhetoric, which is a technique of persuasion.
