tokens: Based on the principle of the world 's heat death , Oswald Spengler 's model of history postulates that any " culture " is a supraorganism that begins its life cycle as a " low-temperature gas " of loosely interconnected vital & # 8209 ; heat & # 8209 ; rich rural individuals pulled together by self-gravitation , which condenses their vital heat to ever higher temperatures and thus causes its radiative loss , so that the individuals are forced to use their dwindling vital heat ever more synergetically by undergoing a series of phase transitions towards a " civilization " , which is a " high & # 8209 ; temperature crystal " of densely interconnected vital & # 8209 ; heat & # 8209 ; deficient urban individuals .
