 A third problem is that, in some cases in which an individual’s states do seem contentful, the ideal environment strategy, as stated above, seems to yield the wrong content. In the most obvious sense, I am better suited to worlds that do not contain a homicidal maniac who wants to kill me than I am to worlds that do contain such a maniac, even if I believe that such a maniac exists. So it seems that the ideal environment strategy will not correctly include the content of this belief among those it attributes to me. (Related examples are offered by Stalnaker 1989, White 1991, and Chalmers 2002.) As Stalnaker notes (1999: 182–183), Dennett is better understood to mean, not that the worlds I am best suited to are those in which I would do best, but rather that they are those with which I am best prepared to cope. But refining this account is a challenging task. (For instance, martial arts training might prepare me to cope with dangers that I do not believe to exist, raising the worry that the ideal environment strategy on this interpretation will attribute to me beliefs I do not in fact have.)
