下定义原则:1.与辩题有清晰的逻辑关系2.不能理所当然3.不能设定在过去或将来。
purpose:
1.to contextualize the debate
Example:
THW use children in the front line during war times.
For this motion, we can set the debate in a
certain middle-east country so that both sides can have enough room to build their cases.
2.to provide yardsticks
Example:
THBT drone striking is a legitimate foreign policy.
In this motion, "a legitimate foreign policy"should be defined so as to provide criteria/yardsticks comparing the costs and benefits of the policy. "A legitimate foreign policy" should be legitimate in the US legal system and can best serve the national interests of America.
3.to clarify ambiguous terms
Example:
THW disallow workers of essential sectors from1 striking.
In this motion, "disallow" should be defined as"prohibit", while "essential sectors" refers to a body of people in our society who are providing essential services without which the normal order might be compromised, for example, police, doctors and so on,
