„There can be no doubt that the youth of today have to be protected against certain poisonous effects inherent in present-day civilization. Five social diseases surround them, even in early childhood. There is the decline in fitness due to modern methods of locomotion; the decline in initiative due to the widespread disease of spectatoritis; the decline in care and skill due to the weakened tradition of craftsmanship; the decline in self-discipline due to the ever-present availability of tranquilizers and stimulants, and the decline in compassion, which William Temple called "spiritual death."“
