conviction, and of emancipation of understanding as emancipation from the duty of settling whether important propositions are true or false, had not dawned on Voltaire. He had just as little part or lot in the complaisant spirit of the man of the world, who from the depths of his mediocrity and ease presumes to promulgate the law of progress, and as dictator to fix its speed. Who does not know this temper of the man of the world, that worst enemy of the world? His inexhaustible patience of abuses that only torment others; his apologetic word for beliefs that may perhaps not be so precisely true as one might wish, and institutions that are not altogether so useful as some might think possible; his cordiality towards progress and improvement in a general way, and his coldness or antipathy to each progressive proposal in particular; his pygmy hope that life will one day become somewhat better, punily shivering by the side of his gigantic conviction that it might well be infinitely worse. To Voltaire, far different from this, an irrational prejudice was not the object of a polite coldness, but a real evil to be combated and overthrown at every hazard. Cruelty was not to him as a disagreeable dream of the imagination, from thought of which he could save himself by arousing to sense of his own comfort, but a vivid flame burning into his thoughts and destroying peace. Wrong-doing and injustice were not simple words on his lips; they went as knives to the heart; he suffered with the victim, and consumed with an active rage against the oppressor. Nor was the coarse cruelty of the inquisitor or the politician, who wrought iniquity by aid of the arm of flesh, the only kind of injury to the world which stirred his passion. He had imagination enough and intelligence enough to perceive that they are the most pestilent of all the enemies of mankind, the sombre hierarchs of misology, who take away the keys of knowledge, thrusting truth down to the second place, and discrowning sovereign reason to be the serving drudge of superstition or social usage. The system which threw obstacles into the way of publishing an exposition of Newton’s discoveries and ideas was as mischievous and hateful to him, as the darker bigotry which broke Calas on the wheel because he was a Protestant. To check the energetic discovery and wide propagation of scientific truth, he rightly held to be at least as destructive in the long run to the common weal, as the unjust extermination of human life; for it is the possession of ever more and more truth that makes life ever better worth having and better worth preserving. And must we not admit that he was right, and that no age nor school of men nor individual has ever been mortally afraid, as every good man is afraid, of inflicting any wrong on his fellow, and has not also been afraid of extinguishing a single ray from the great sun of knowledge?
