This is another of Kennedy's attacks against the psychoanalyst who 'divorces soma and psyche and who seems to see like Polyphemus with but a single eye'. Neurology and internal medicine must be the basis of psychiatry, and a pathology of neuroses and psychoses must be developed through medicine. The author mentions various disorders which were in earlier days considered as neuroses, and whose organic etiology has been discovered later. 'We have', says Kennedy, 'in shock therapy an attack on mental illness which means to the treatment of disorders of the "mind" what the appearance of Lister's carbolic spray meant to surgery.'
