Universal obedience is universal stagnation; disobedience is one of the conditions of progress. Select any age of the world and tell me what would have been the effect of implicit obedience. Suppose the church had had absolute control of the human mind at any time, would not the words liberty and progress have been blotted from human speech? In defiance of advice, the world has advanced.
Robert Green Ingersoll – “Individuality” (1873)
