In introducing the reactive attitudes “of people directly involved in transactions with each other,” P.F. Strawson lists “gratitude, resentment, forgiveness, love, and hurt feelings." Because he decided to illustrate his larger points about responsibility by focusing on resentment (via an investigation into its standard excusing and exempting conditions), nearly everyone writing about responsibility in Strawson’s wake has done so as well. But what of the remaining reactive attitudes?
In this paper I contrast two conceptions of the structure of lives: the “stream of behavior” framework (which I call “flat”) and the “concurrent strand” framework (which I call “deep”). The stream of behavior approach goes back at least to William James.
