We have spoken of the marked individuality in William Penn's character which led him to continue to wear the court costume after he became a Friend, until his own conscience demanded that he should adopt the Quaker garb. The same individuality led him to diverge from the ordinary type of Friend in another and more important matter. They were bent on fighting out the battle of religious liberty by religious, rather than by political weapons. They might, when on trial, quote a statute or plead a precedent as a sort of argumentum ad hominem, but in political and constitutional affairs, as such, they as a class took no delight. Penn was an exception. He felt a keen interest in the political affairs of his country. He saw that it was a mistake to lose the benefit of the old charters and statutes which secured the liberty of the subject, and he appealed to them on all occasions. This appeal served two purposes. It acknowledged the civil duties of Christians, which some Christians are slow to recognise. It also secured the sympathies of many in their struggles to whom the religious aim was incomprehensible. Both these objects seemed to Penn of the highest importance; they influenced his whole career. In the words of W. E. Forster, "the form of his religion, his feelings as a Quaker, did not seem to him to interfere with the fulfilment of his duties as a citizen. Had it done so, that form would have been changed rather than the work left undone, for he was not a man to make one duty an excuse for shirking another; within his conscience there was no conflict between religion and patriotism; he did not fly from the world, but faced it with true words and true deeds."
