Psychology is the science of psychic states both as to content and form, regarded from an objective standpoint, and brought in relation to the living corporeal individual.

Psychology must postulate uniformity of interrelation of physical, physiological, and psychic processes.

The fact that psychology postulates an external material world and studies it in so far as it comes to be reflected in consciousness, points to another postulate which psychology must assume in addition, namely, the existence of an inner world consciousness.

The main source of psychopathic diseases is the fundamental instinct of fear with its manifestations, the feeling of anxiety, anguish, and worry.

Human institutions depend for their existence and stability on the impulse of self-preservation and its close associate, - the fear instinct.

The general tendency of evolution is from structure to function, from bondage to freedom of the individual elements.

Self-preservation is the central aim of all life-activities.
