Modesty has moved from the organ of ambition. Modesty has settled upon the organ of conviction — where it was never meant to be. A man was meant to be doubtful about himself, but undoubting about the truth: this has been exactly reversed. Nowadays the part of a man that a man does assert is exactly the part he ought not to assert — himself. The part he doubts is exactly the part he ought not to doubt — the Divine Reason. Huxley preached a humility content to learn from Nature. But the new sceptic is so humble that he doubts if he can even learn. Thus we should be wrong if we had said hastily that there is no humility typical of our time. The truth is that there is a real humility typical of our time; but it so happens that it is practically a more poisonous humility than the wildest prostrations of the ascetic. The old humility was a spur that prevented a man from stopping: not a nail in his boot that prevented him from going on. For the old humility made a man doubtful about his efforts, which might make him work harder. But the new humility makes a man doubtful about his aims, which will make him stop working altogether.
