To illustrate the idea of subjective satisfaction, suppose I bought a pair of basketball shoes after watching an ad where someone puts them on and starts dunking. I might feel as though I have more spring in my jump and also might have a sense of being more athletic once I wear the new shoes. This sense of having more spring in my jump and feeling more athletic are cases of subjective satisfaction. In order for my desire of the shoes to be rational, Arrington would insist that there must be more I get from the shoes than mere subjective satisfaction.
