   Syn: To Discuss, Examine, Debate. We speak of examining
        a subject when we ponder it with care, in order to
        discover its real state, or the truth respecting it. We
        speak of discussing a topic when we examine it
        thoroughly in its distinct parts. The word is very
        commonly applied to matters of opinion. We may discuss a
        subject without giving in an adhesion to any conclusion.
        We speak of debating a point when we examine it in
        mutual argumentation between opposing parties. In debate
        we contend for or against some conclusion or view.
        [1913 Webster]
