 Closely related to these philosophical concerns about responsibility are issues involving the personality disorders, which, due to their long-recognized relationship to more normal character weaknesses, and their evidently dimensional nature, sit uneasily within psychiatric classifications (Sinnott-Armstrong 2008; Radden 2011; Pickard 2011). Among one DSM grouping (cluster B personality disorders, including borderline, narcissistic and antisocial), additional distinguishing features have been observed: their symptoms are described using moralistic language. Rather than medical entities, susceptible to medical treatments, they are better approached using persuasion, and methods reminiscent of the “moral treatment” of earlier times, Louis Charland argues (Charland 2004).
