When they are aggressive__or even worse, when they panic__both humans and animals demonstrate a subconscious drive only for self-survival. For instance, when a great theater fire disaster occurs and the flames quickly exhaust all the oxygen, people suffocate within two minutes. When the fire is over and many of the human dead are found inside unscorched, their deaths having been caused by suffocation, we discover that the otherwise loving fathers lost personal consciousness and stampeded over their own children and crushed them to death__the children for whom the conscious fathers would gladly have given their lives a hundred times over.
