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.

The tendency of life is not the preservation of the species, but solely the preservation of each individual organism, as long as it is in existence at all, and is able to carry on its life processes.

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

Mental synthesis of psychic content in the unity of a moment-consciousness is a fundamental principle of psychology.

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

If society is to progress on a truly humanistic basis, without being subject to mental epidemics and virulent social diseases to which the subconscious falls an easy victim, the personal consciousness of every individual should be cultivated to the highest degree possible.

The psycho-physiological hypothesis is both inductively and deductively the sine qua non of the science of psychology.
