Examples and Observations:
- "An argument is any group of propositions where one proposition is claimed to follow from the others, and where the others are treated as furnishing grounds or support for the truth of the one. An argument is not a mere collection of propositions, but a group with a particular, rather formal, structure.
"The conclusion of an argument is the one proposition that is arrived at and affirmed on the basis of the other propositions of the argument.
"The premises of an argument are the other propositions which are assumed or otherwise accepted as providing support or justification for accepting the one proposition which is the conclusion. Thus, in the three propositions that follow in the universal deductive categorical syllogism. the first two are premises and the third the conclusion. All men are mortal.

Socrates is mortal. Premises and conclusions require each other. A proposition standing alone is neither a premise nor a conclusion."

Argument is the core of the debate speech --the superior debater must be superior in the use of argument. The chief means of persuasion in debate is the logical mode."
