We shall have done our work but badly so far if we have not made it clear that Erasmus believed in his right to bring all human institutions to judgment at the bar of his own mind and conscience. Nothing which offended his own sense of right could be wholly acceptable to him. In so far he was an individual, and claimed his right as such. As an individual, with a mind and conscience of his own, he had a right, not only to have opinions upon every subject of human interest, but to express them. There was no call upon him, any more than upon a hundred others, to address himself thus to kings, princes, prelates, popes, inquisitors, and instruct them as to their duty in a great public crisis. He did this out of some impelling sense of duty and of right. If we may put any confidence in anything he ever said or did, we may rely upon this: that he felt himself the spokesman of a cause greater than himself,--the cause of a free and sane scholarship. He was an individual, but of the fifteenth, not of the eighteenth century. The great word of deliverance to the modern mind, the "_cogito ergo sum_," had not yet been spoken. Man was still content to think of himself as hemmed in by standards of thought and action not created for him by his own mind, but given to him as a part of his human inheritance from the traditions of the past. No estimate of individual force can be complete without this limitation. If Erasmus had lived in the eighteenth century, he might have been a Voltaire; but he was not living in the eighteenth century. He saw where his time was out of joint, but he did not believe himself called upon to set it right. His function was only to point out the evils and, so far as he could, to appeal to those in authority to remedy them. A man merely timid and nothing more could have found a far easier way to keep himself safe from any danger of persecution. He might simply have kept silent, and no one could have said it was his duty to speak out. It required a very considerable exercise of courage to say even as much as Erasmus was willing to say, in a day when Savonarola had so lately been done to death for merely attempting to set up in Florence a kingdom of Christ without the help of the pope. The arm of the Inquisition was long, its watch was vigilant, and its weapons were subtle. A man who valued merely his own peace of mind would hardly be likely to incur its displeasure. So far we may go in granting to Erasmus the quality of courage. He knew he was making enemies among powerful vested interests. If his principles of sound learning and reasonable criticism were to prevail, then, as he frequently said, the profits of a vast body of place-holders and traders in all sacred things were going to be diminished, and they would not suffer this without making a great demonstration of their power.
