However, further reflection grounded on what is still anecdotal clinical evidence, easily leads to unwarranted speculation. For the moment, it seems sufficient to have found a bridge toward another field of inquiry and to have identified a promising point for future research on anosognosia. The last issue to be considered concerns a particular type of self-related beliefs: the belief that a certain activity performed by the organism is an activity willed by the subject himself.
