Originally published in 1928 in the Psyche Miniatures Medical Series, this title was an attempt to bring to the attention of British psychologists and psychiatrists some aspects of the work and thought of French psychologist Charles Blondel. Well known abroad but little known in England at the time, he was professor of Psychology at the University of Strasbourg and founder of a school of 'morbid psychology'.


This book contains two papers, the first concerning the theory of the disordered mind and the second deals with the relation between disordered thought and speech. Today it can be read and enjoyed in its historical context.
