In dealing with self-complacency let him discriminate between vanity and pride, between pride and dignity. Let him show that humility and dignity are consistent with one another, yes, that they are complementary aspects of one and the same moral quality.

The moral terms as a rule are loosely used, and this can not but lead to confusion in their application. Precise definitions, based on thorough discussion, are an excellent means of moral training.
