" He does not regard “because I want it” or “because I feel like it” as a sufficient cause and validation of his actions. He chooses and/or identifies his desires by a process of reason, and he does not act to achieve a desire until and unless he is able rationally to validate it in the full context of his knowledge and of his other values and goals. He does not act until he is able to say: “I want it because it is right. "
