A contestation between two or more persons, in which they take different sides of a question, and maintain them, respectively, by facts and arguments; or it is a discussion, in writing, of some contested point. 2. The debate should be conducted with fairness, candor and decorum, and supported by facts and arguments founded in reason; when, in addition, it is ornamented by learning, and decorated by the powers of rhetoric, it becomes eloquent and persuasive. It is essential that the power of debate should be free, in order to an energetic discharge of his duty by the debator. 3. The Constitution of the United States, art. 1, s. 6, provides, that for any speech or debate, in either house, the senators and representatives shall not be questioned in any other place. 4.
