If some men attempt to survive by means of brute force or fraud, by looting,
robbing, cheating or enslaving the men who produce, it still remains true that
their survival is made possible only by their victims, only by the men who
choose to think and to produce the goods which they, the looters, are seizing.
Such looters are parasites incapable of survival, who exist by destroying those
who are capable, those who are pursuing a course of action proper to man.
The men who attempt to survive, not by means of reason, but by means of force,
are attempting to survive by the method of animals. But just as animals would
not be able to survive by attempting the method of plants, by rejecting
locomotion and waiting for the soil to feed them—so men cannot survive by
attempting the method of animals, by rejecting reason and counting on
productive men to serve as their prey. Such looters may achieve their goals
for the range of a moment, at the price of destruction: the destruction of
their victims and their own. As evidence, I offer you any criminal or any
dictatorship.
