Summary

An exception to a generalization is applied to cases where the generalization should apply.

Examples

1. Because we allow terminally ill patients to use heroin, we should allow everyone to use heroin.
2. Because you allowed Jill, who was hit by a truck, to hand in her assignment late, you should allow the entire class to hand in their assignments late.

Proof

Identify the generalization in question and show how the special case was an exception to the generalization.
