A Lincoln-Douglas debate case contains five structures of the main sermon, including the introduction, definitions, value, points and conclusion. A Lincoln-Douglas debate revolves around an oration style that flows easily from point to point as evidence supports the speech's thesis and conclusion.
The introduction catches a judge's attention and denotes what stance the debater takes on the given topic. For example, if the topic opposes legalizing marijuana, the introduction may relate a story of someone who died from marijuana usage.
The second part delineates definitions used throughout a person's debate. Definitions keep misinterpretations of words to a minimum and prevent an opponent from misusing a debater's words. For example, a debater may define "illegal drug" according to the schedule of controlled substances published by the U.S. Department of Justice to prevent any misconstruction later in the debate.
The third and most lengthy part of a Lincoln-Douglas debate is the value portion. A value defines the standard or principle on which a debater's argument resolves. Winning this type of debate stems from supporting values that are better than the opponent's values. A value proposition such as, "Marijuana should not be legalized because of its effects on the human brain," must be supported by medical evidence of detrimental effects.
Points are opinions and contentions made to support a particular case that are backed by facts and logic. Points then lead to the conclusion that wraps up a person's argument.
