The sovereigns demanded of Clement XIV that the expulsion of the Jesuits from their territories should be approved, and the society entirely suppressed and abolished. Upon the other hand, the Jesuits insisted, with their accustomed superciliousness, that it was necessary to the Church and the cause of Christianity that they should be restored to public favor by his pontifical indorsement. This issue confronted him at the beginning. At first he somewhat excited the hopes of the Jesuits by the course he took against the French philosophers, and the bulls of excommunication he issued against Diderot, d'Alembert, Voltaire, Helvetius, Rousseau, Marmontel, and Holbach. This stimulated them afresh, and by their machinations created a party in France, headed by Louis XV, which demanded their return to that country. But the pope was not driven from the plain line of his duty, which required of him that the investigation already entered upon should be completed, and that the questions involved should be decided according to right and justice. This was due to the sovereigns, to the public, and especially to the Church. Cormenin says he was suspicious of being dealt with like his predecessor, and that he took the necessary precautions to guard against it, by substituting a faithful monk for the cook of the Quirinal, so as to guard against the possibility of poison. Howsoever this may have been, he persevered in his course with the courage of a man who fears no evil when in the faithful discharge of duty. Resolved, however, not to act with undue haste, but to have all the matters brought fully before him, together with the evidence bearing upon them, he continued the investigation for the period of four years, so that when his final decision was made the world should be convinced that it was the result of calm deliberation and honest conviction. He says of himself that he "omitted no care, no pains, in order to arrive at a thorough knowledge of the origin, the progress, and the actual state of that regular order commonly called the Company of Jesus;" and Ranke, the great historian, says he "applied himself with the utmost attention to the affairs of the Jesuits;" and adds that "a commission of cardinals was formed, the arguments of both sides were deliberately considered," before his conclusion was announced.[136] No greater deliberation and no more serious reflection could have been bestowed upon any question. The evidence was carefully inspected and everything duly considered. The scales were held at equipoise until the preponderance of proof caused the beam to turn against the Jesuits, when he was constrained by a sense of duty to the Church, to Christianity, to the public, and to his own conscience, to announce the result which gave peace and quiet to the nations and joy to the great body of Christians throughout Europe. This he did July 21, 1773, by issuing his celebrated bull, "_Dominus ac
