Cumulative Record. Chapter 22: Compassion and Ethics in the Care of the Retardate. Quote 1

If our feelings do not explain our behavior, some other explanation for right or wrong or good or bad conduct must be found. Ethical and moral principles must then be derived from the reasons why people behave (and only incidentally feel) as they do. The point is important because we can change reasons more directly than feelings, and a reformulation may therefore improve our chances of inducing people to behave ethically. (p. 329)
