Penn's attainments were already considerable for his years, yet his College course was doomed to be a failure. The most noteworthy occurrences in it were, his again hearing the Quaker preacher, Thomas Loe, and his vigorous opposition to the Ritualistic innovations of the Stuarts. The authorities insisted on the gown being worn by all under-graduates. Penn and others, recognising this as the thin end of the Popish wedge, not only would not wear it themselves, but tore it from the backs of those who did. This led to his expulsion for rioting.[7] His father was most annoyed at the disgrace attending the punishment, until he found that his son's conduct resulted from settled convictions, already firmly rooted. Then the Admiral at once understood the serious issues involved. He must vanquish these conscientious scruples or his ambitious plans would be ruined. He never planned a sea-fight more carefully. In the first moment of anger he had soundly whipped his son, and turned him out of doors; now he tried gentler and more insinuating means. Like a true man of the world, he had full confidence in the power of a gay life to cast out such thoughts, and he sent his son to Paris. The most interesting incident of the trip is his treatment of a French gallant, who insisted on fighting him over some supposed insult. In vain did Penn politely explain that no insult had been offered. They must fight. Penn not only excelled in athletics, but was a skillful fencer. He soon disarmed the man, but instead of then punishing him for his quarrelsomeness, he only returned him his sword with a polite bow. [7] He tells us that his expulsion resulted from his writing a book, which "the priests and masters did not like." Probably both reasons were combined. Sir William Penn, delighted with what he heard of the success of this expedient, determined that his son should finish his education in France, after which he destined him for the army. But in God's providence, the chosen tutor, the learned divine Moses Amyrault, if he did not deepen the gracious impressions already received, grounded him thoroughly in theological studies, which were very useful to him afterwards. Leaving him, Penn travelled for some time, and returned home, says Pepys, "a fine gentleman." He then studied law awhile in Lincoln's Inn, and to good purpose, as we shall see.
