 This strategy is proposed by Dennett (1982). The idea is that a (centered) world is included in one’s narrow content if and only if it is a world to which one is ideally suited. Place a subject in some environments, and everything will work out extremely well: the subject’s attempts to satisfy his or her desires will succeed every time. Other environments will be much less friendly; somehow the subject’s actions will never turn out to have quite the desired effects. Dennett’s thought is roughly that we can capture the way the world is from the subject’s point of view by taking the set of centered worlds to which the subject is ideally adapted. One attraction of this strategy is that it does not make narrow content parasitic on broad content; another is that it does not require the subject to be able to answer questions or reflect on the content of the subject’s thoughts, so that it could easily be applied to cats and dogs as well as to humans.
