The book begins by exploring the foundational place of habit in human conduct, defining habits not as passive mechanical routines, but as active working adaptations that incorporate both the individual organism and the social environment. Dewey critiques traditional moral theories that separate character from actual conduct or view morality as a set of static rules imposed upon an inherently depraved human nature. Instead, he demonstrates how habits are inherently social functions, arguing that social issues like crime or poverty cannot be blamed solely on individual free will, but must be addressed by modifying the objective conditions and social environments that shape human behavior.
In the second part, the text examines the vital role of impulse in conduct. Dewey shows how native impulses act as the dynamic starting points and pivots for the reorganization of rigid habits, preventing society from stagnating. While uncaught impulses can lead to chaos or pathology, and over-organized customs can suppress human potential, intelligent redirection of native activities enables continuous personal and social growth. He applies this framework to re-examine historical institutions such as war and the modern economic wage-system, showing that they are not immutable products of fixed human instincts like pugnacity or acquisitiveness, but rather complex social patterns capable of being transformed.
The third part focuses on intelligence and deliberation. Dewey redefines deliberation not as a mathematical calculus of future pleasures and pains, but as a dramatic rehearsal in imagination where competing habits and impulses are weighed and unified. Rationality emerges as a harmonious coordination of diverse desires, rather than an abstract faculty opposed to passion. Knowledge and moral judgment are presented as practical tools developed through experience to resolve actual entanglements in conduct, rather than revelations from a separate, transcendental realm.
Finally, Dewey emphasizes that morals are inherently human and social, rejecting the division between an inner private life and the public world of action and politics. True freedom is found not in isolated romantic spontaneity or blind conformity to ancient custom, but in the intelligent, experimental adjustment of habits to a changing environment. By recognizing the continuity between nature, human psychology, and society, individuals can approach recurring difficulties with a growing fund of knowledge, transforming moral struggle into a continuous, creative process of social betterment.
