 The desire-to-desire theory is the last in a sequence of three attempts to provide a foundation for ethics by defining “good” in terms of desire. In the first, “X is good” means “X will satisfy my desires”; in the second, it means “I want X for its own sake”; and in the third it means “X is what I desire to desire” (RoE: chs. 7, 9 &amp; 10/Papers 1: nos. 36, 39 &amp; 15).
