  • Edouard Seguin and the Physiological Method

    "Seguin had come to believe that idiocy was not the result of deficiency or malformation of the brain or nervous system, but was simply an arrest of mental development that occurred either before, at, or after birth due to variety of causes. Moreover, in Seguin’s view, the disability could be overcome by appropriate treatment. That treatment was called the Physiological Method and was propagated in Seguin’s important 1844 text, Traitement Moral, Hygiene, et Education des Idiots." Page 7
