Thinking otherwise than is customary - that is by no means so much the activity of a better intellect, as the activity of strong wicked inclinations - severing, isolating, refractory, mischief-loving, malicious inclinations. Heresy is the counterpart of witchcraft, and certainly just as little a merely harmless affair, or a thing worthy of honour in itself. Heretics and sorcerers are two kinds of bad men; they have it in common that they also feel themselves wicked; their unconquerable delight is to attack and injure whatever rules -whether it be men or opinions. The Reformation, a kind of duplication of the spirit of the Middle Ages at a time when it had no longer a good conscience, produced both of these kinds of people in the greatest profusion.
