Ignorance is of a peculiar nature; once dispelled, it is impossible to reestablish it. It is not originally a thing of itself, but is only the absence of knowledge; and though man may be kept ignorant, he cannot be made ignorant.
Thomas PaineThat there are men in all countries who get their living by war, and by keeping up the quarrels of nations, is as shocking as it is true; but when those who are concerned in the government of a country, make it their study to sow discord and cultivate predjudices between nations, it becomes the more unpardonable.
