[The 'positive' philosopher of the present day] offers in the stead of Christianity a specious phase of neo-paganism, by which the nineteenth century after Christ may be assimilated to the golden age of Mencius and Confucius; or, in other words, may consummate its intellectual freedom, and attain the highest pinnacle of human progress, by reverting to a state of childhood and of moral imbecility.
