L. T. Hobhouse 
Social Development (Routledge Revivals) 
Its Nature and Conditions

Originally published in 1924, Professor Hobhouse»s theories and commentaries upon social development are an important milestone in the history of sociological thought. Of particular interest to the modern sociologist is his delineation of the struggle of the human mind towards rationality in thought and action and his insistence on the principle that in all social investigations it is necessary to distinguish between questions of fact and questions of value.
