OUT of the scientific acquisitions thus set forth, elaborated by the spirit we have just described, is born a doctrine, seemingly a revelation, and which, under this title, was to claim the government of human affairs. On the approach of 1789 it is generally admitted that man is living in "a century of light," in "the age of Reason;" that, previously, the human species was in its infancy and that now it has attained to its "majority." Truth, finally, is made manifest and, for the first time, its reign on earth is apparent. The right is supreme because it is truth itself. It must direct all things because through its nature it is universal. The philosophy of the eighteenth century, in these two articles of faith, resembles a religion, the Puritanism of the seventeenth century, and Islam in the seventh century. We see the same outburst of faith, hope and enthusiasm, the same spirit of propaganda and of dominion, the same rigidity and intolerance, the same ambition to recast man and to remodel human life according to a preconceived type. The new doctrine is also to have its scholars, its dogmas, its popular catechism, its fanatics, its inquisitors and its martyrs. It is to speak as loudly as those preceding it, as a legitimate authority to which dictatorship belongs by right of birth, and against which rebellion is criminal or insane. It differs, however, from the preceding religions in this respect, that instead of imposing itself in the name of God, it imposes itself in the name of Reason.
