This is an exaggeration. We have seen that amongst the nature-gods of Mexico there was one, Tezcatlipoca, who was looked upon as the austere guardian of law and morals. If we are to believe Father Sahagun,--and even if we allow for strong suspicions as to the accuracy of his translations of the prayers and exhortations uttered under certain circumstances by parents and priests,--it is evident that the Mexicans were taught to consider a decent and virtuous life as required by the gods. Indeed, they had a system of confession, in which the priest received the statement of the penitent, laid a penance on him, and assured him of the pardon of the gods. Generally the penitents delayed their confession till they were advanced in age, for relapses were regarded as beyond the reach of pardon.[27] It would be nearer the truth to say that the religious ethics of the Mexicans had entered upon that path of dualism[28] by which alone, in almost every case, the normal synthesis or rational reconciliation of the demands of physical nature and the moral life has been ultimately reached. For inasmuch as fidelity to duty often involves a certain amount of suffering, the suffering comes to be regarded as the moral act itself, and artificial sufferings are voluntarily incurred under the idea that they are the appointed price of access to a higher and more perfect life, in closer conformity with the divine will. The cruel rites which entered into the very tissue of the Mexican religion could hardly fail to strengthen the same ascetic tendency, by encouraging the idea that pain itself was pleasant to the eyes of the gods. But the truth is that in this matter we can discern no more than tendencies. There are symptoms of men's minds being busy with the relation of the moral to the religious life, but no fixed or systematic conclusions had been reached. It might, perhaps, have been otherwise in the sequel, and these tendencies might ultimately have taken shape in corresponding theories and doctrines, had not the Spanish conquest intervened to put an end for ever to the evolution of the Mexican religion. I have frequently spoken of the Mexican priests, and the time has now come for dwelling more explicitly on this priesthood.
