 It is also important to understand whether we can be regarded as morally responsible for our actions if we engage in morally problematic behaviour or commit acts of violence or other crimes that are motivated by our delusions. As a consequence of the failures of rationality and self knowledge that characterize some delusions, we may appear as if we are ‘in two minds’, and we may not always present ourselves as unified agents with a coherent set of beliefs and preferences (e.g., Kennett and Matthews 2009). As a result, we may be judged to be (locally or temporally) unable to exercise our capacity for autonomous thought and action.
