Determining the Effectiveness of the Reasons
If a reason is effective (or "good"), it invokes a value we can believe in and agree with. Value judgments, because they are by necessity somewhat subjective, are often the most difficult to make in arguments. It is, therefore, always a good idea to restate the value being invoked as clearly as possible in your own terms. Then you'll be able to evaluate whether or not the value is good in itself or worth pursuing.
