The lack of agency becoming part of the self

This brief commentary on Greenberg's article ‘When the illness speaks’ addresses the problem of agency in mental disorder. Complementing the perspective of the article, it advocates an approach that does not see the causal mechanism of disorder-related behaviour in terms of an exclusive disjunction between the effects of the individual patient's own agency or manifestations of the illness. When reduced agency becomes part of the person's self-conception, passivity no longer means behaviour that is alien to their ‘genuine self’. Relatedly, the requirement that the patient's self-conception be validated raises some questions regarding its therapeutic constraints.
