Violet Mary Firth 
The Machinery of the Mind 

ORIGINALLY given as a popular lecture course, this little book does not pretend to be a contribution to the formidable array of psychological literature. It is intended for those who have neither the time nor the training necessary to assimilate the standard works on the subject, but who want to know its elements and to understand the principles on which our characters are formed and the means by which the process of thought is carried on, not so much from the scholastic point of view, but in relation to the problems of everyday life.
