 Appeals to authenticity also face problems related to our ability to distinguish truly inauthentic values from new but still authentic ones. Not all new values are inauthentic, for it is possible for a person to autonomously change her mind. Moreover, sometimes illness gives us experiences that seem highly relevant to our choices. Having once experienced illness we may be inclined to make decisions we would never have expected ourselves to make before we were ill. The decisions are not caused by our illness, but rather reflect what we have learned from illness. As such they should not count against capacity. But to ensure this doesn’t happen we need reliable ways of distinguishing cases that can, in fact, be very hard to distinguish from the outside. [Also, insofar as we are looking for suspicious changes in values as signs of inauthenticity, this will not help in many cases of anorexia nervosa, where the patients in question typically acquire the illness at a very young age before they have developed characteristic values distinguishable from the values of the illness.]
