 The kernel of truth in this statement is that some of the most valuable components of our lives are not available by following a rule. We do not fall in love with people by applying a general principle, standard, or criterion about whom we ought to fall in love with. We do not develop a passion for mathematics, or history, or tennis, by seeing these pursuits as specific instances of something more general that we care about. Some of the most valuable components of our lives are available to us only if they arise spontaneously from feelings that respond to the lovable features of the world or the people in it.
