THEMES FOR DEBATE.

Following are one hundred and fifty topics for debate. The more usual form in their presentation is that of a direct proposition or statement, rather than that of a question. The opponents then debate the "affirmative" and "negative" of the proposition. It is well to be very careful, in adopting a subject for a debate, to so state or explain it that misunderstandings may be mutually avoided, and quibbles on the meaning of words prevented.
