But not only is all friendly communication forbidden to the Jesuit, but he is also placed under constant espionage. He is never permitted to walk about alone, but, whether in the house or out of doors, is always accompanied by _two_ of his brethren.[31] Each one of this party of three acts, in fact, as a spy upon his two companions. Not, indeed, that he has special instructions from his superior to do so, but, knowing that they, as well as himself, have been taught that it is their duty to inform the General of every suspicious or peculiar expression uttered in their hearing, he is under constant fear of punishment, should either of them report anything regarding the other which he omits to report likewise. Hence it is very seldom that a Jesuit refrains from denouncing his companion. If he does not do so at once, his _sinful neglect_ becomes revealed in the confessional, to the _special_ confessor appointed by the superior. Then, in order that these members, so submissive in action to their General, should not differ in opinion among themselves and so occasion scandal in the Catholic world, and to oppose an uniformity of doctrine to that of the free examen of the Protestants, the Constitution decrees as follows:—“Let all think, let all speak, as far as possible, the same thing, according to the apostle. Let no contradictory doctrines, therefore, be allowed, either by word of mouth, or public sermons, or in written books, which last shall not be published without the approbation and the consent of the General; and, indeed, all difference of opinion regarding practical matters should be avoided.”[32] Thus, no one but the General can exercise the right of uttering a single original thought or opinion. It is almost impossible to conceive the power, especially in former times, of a General having at his absolute disposal such an amount of intelligences, wills, and energies.
