ABSTRACT
Many national policies are founded upon fear, as has been clearly shown forth during the aftermath of the World War. The secretion of the thyroid gland is an essential for rapid functioning of the living cell; and this is highly stimulated by fear. Fear stimulates the secretion of the adrenal gland, which constricts the blood supply to the vegetative organs in the abdomen, while it dilates blood vessels which go to the voluntary muscles and the nervous system as well as to the lungs and heart. The aforementioned burning up of waste products preventing fatigue is the explanation of the strength fear brings. Fear is the foundation of respect for others, without which there can be no social life. The fear of what threatened primitive man aroused him to circumvent it and hence developed his intelligence by provoking intellectual interests.
