should use it.

The term "debate," in the sense in which students of these subjects
should use it, means _oral argumentation carried on by two opposing
teams under certain prescribed regulations, and with the expectation
of having a decision rendered by judges who are present_. This is
"debate" used, not generally, as you used it in saying, "I debated
with a friend," but technically, as we use it when we refer to the
Yale-Harvard debate or the Northern Debating League. In order to keep
the meaning of this term clearly in mind, use it only when referring
to such contests as these. In speaking of your argumentative
conversation with your friend or of the forensic contests between
Lincoln and Douglas, use the term "discussion" rather than "debate."

It is true that the controversy between Lincoln and Douglas conformed
to our definition of "debate" in being oral; moreover, at least in
sense, two teams (of one man each) competed, but there were no judges,
and no direct decision was rendered.

Since argumentation, then, is the art of producing in the mind of
someone else a belief in the idea or ideas you wish to convey, and
debate is an argumentative contest carried on orally under certain
conditions, it is clear that argumentation is the broader term of the
two and that debate is merely a specialized kind of argumentation.
Football is exercise, but there is exercise in many other forms.
Debate is argumentation, but one can also find argumentation in many
other forms.

The following diagram makes clear the work we have covered thus far.
It shows the relation between argumentation and debate, and shows that
