Liberty cannot be sacrificed for the sake of temperance, for the sake of morality, or for the sake of anything. It is of more value than everything. Yet some people would destroy the sun to prevent the growth of weeds. Liberty sustains the same relation to all the virtues that the sun does to life.

— Robert Green Ingersoll
