The machinery of the mind by Violet M. Firth is a concise, popular introduction to psychology and psychotherapy written in the early 20th century. It explains how modern psychology conceives the structure and functions of the mind and applies that understanding to everyday behavior, mental distress, and practical self-care.

The work sketches the mind as layered—focus and fringe of consciousness, a foreconscious store of accessible memories, a deeper subconscious, and an automatic level—filtered by “censors” that regulate what reaches awareness. It shows how ideas cluster into emotionally charged complexes, how memory and association work, and how three core instincts—self-preservation, reproduction, and the social (herd) instinct—drive feeling and conduct, including the development and possible disorders of sexuality. Mental trouble is framed as maladaptation: conflicts between instincts, or between person and environment, may lead to repression, dissociation, symbolic substitutions, and the wish-fulfilling logic of phantasies, dreams, and delusions. The book surveys therapies—psychoanalysis (contrasting Freud and Jung), word-association, hypnosis, suggestion, and autosuggestion—while advocating re-education, thought control, and sublimation (redirecting energy into creative outlets) over crude repression. Practical tips address concentration, memory by association, trusting subconscious problem-solving, and guarding against harmful self-suggestion. It concludes by urging integration of our primitive drives with reason and social responsibility, aiming at forward-looking adaptation rather than a nostalgic return to the primitive.
