A few instances may serve to show what difficulties the student of religion has to contend with, before he can hope firmly to grasp the facts on which his theories are to be based. Roman Catholic missionaries who had spent their lives in China, who had every opportunity, while staying at the court of Pekin, of studying in the original the canonical works of Confucius and their commentaries, who could consult the greatest theologians then living, and converse with the crowds that thronged the temples of the capital, differed diametrically in their opinions as to the most vital points in the state religion of China. Lecomte, Fouquet, Prémare, and Bouvet thought it undeniable that Confucius, his predecessors and his disciples, had entertained the noblest ideas on the constitution of the universe, and had sacrificed to the true God in the most ancient temple of the earth. According to Maigrot, Navarette, on the contrary, and even according to the Jesuit Longobardi, the adoration of the Chinese was addressed to inanimate tablets, meaningless inscriptions, or, in the best case, to coarse ancestral spirits and beings without intelligence.[2] If we believe the former, the ancient deism of China approached the purity of the Christian religion; if we listen to the latter, the absurd fetichism of the multitude degenerated amongst the educated, into systematic materialism and atheism. In answer to the peremptory texts quoted by one party, the other adduced the glosses of accredited interpreters, and the dispute of the missionaries who had lived in China and knew Chinese, had to be settled in the last instance by a decision of the see of Rome.
