We need not go beyond the Positivists themselves for examples and proofs of this persistence of the religious sentiment. Comte, Spencer, and Littre may be called as witnesses. The founder of Positivism, who had predicted the fatal extinction of the disposition to religion in the human soul, crowned his system and ended his career by founding a new religion, clumsily copied from the sacerdotal organisation and the ritual practices of Roman Catholicism. There actually exists a Positivist Church, with a calendar of saints, with relics and anniversaries, with a catechism, and with a high priest not less infallible than the one at Rome. A few disciples, scandalised by this supreme temptation of the master, desired to excuse him by declaring that he had gone mad. It was a mistake. The fact is that, arriving at the construction of a Positive Sociology, Comte comprehended the _role_ of the religious instinct and of religious feeling in the life of peoples, and he believed that he would only be able to cement the edifice of society in the future by religion. It is said that those who have been amputated sometimes feel sharp twitches in the limbs they have lost. Comte and his disciples have experienced something similar. Nature, with her usual irony, has avenged herself on them for the violence they have done to her. Of Herbert Spencer not much need be said; everybody knows that the _Unknowable_ in his system has become a sort of undetermined and unconscious force, eluding every effort of the mind to grasp it, but remaining, none the less, the cause explaining evolution, and the source profound whence all things flow. Under different names, do we not recognise the First Cause of the philosophers, and the image, half-effaced, of the God of believers? Need we be surprised that the English thinker pronounces religion to be eternal? that he finally reduces the mental life of man to these two essential and primordial activities--the scientific activity which pursues the knowledge of phenomena and their transformation, and religious activity delivering itself up to mystical contemplation and to silent adoration of universal being?
