This article proposes a new strategy to dispel the skeptical conclusion put forward by Thomas Szasz that psychiatry is illegitimate. The skeptical conclusion is based on a radical demarcation between mental and somatic disorders. To minimize this demarcation, Jerome Wakefield uses a conceptual analysis stating that both mental and somatic disorders are harmful dysfunctions. Recent reviews, however, have shown that his analysis stumbles over the practical difficulty of distinguishing normal functions from dysfunctions. Because of this problem, Wakefield’s analysis does not rule out the skeptical conclusion. A new strategy that does not require solving the problem recognized by these critics is therefore preferable to rule out the skeptical conclusion.
