title: Beard's concept of neurasthenia and Freud's concept of the actual neuroses.
abstract: Beard's concept of neurasthenia and Freud's concept of the actual neuroses are described and evaluated critically. Despite differences in the content of their theories, especially in the role of sexual factors and sexual mechanisms, there are important formal and logical similarities. Both Beard and Freud incorrectly identified the causes of the neuroses being studied; both used inadequate methods of assessing the strengths of the causal factors; and the central theoretical concepts of both were equally vacuous. Freud adopted the same method of study as did Beard, but does not seem to have been influenced directly by him.
