It is true that this doctrine, which is the only basis for establishing harmony in our nature, had been, as I before remarked, instinctively accepted by theological systems. But it was one of the fatalities of society in its preliminary phase, that the doctrine was coupled with an error which, after a time, destroyed all its value. In acknowledging the superiority of the heart the intellect was reduced to abject submission. Its only chance of growth lay in resistance to the established system. This course it followed with increasing effect, till after twenty centuries of insurrection, the system collapsed. The natural result of the process was to stimulate metaphysical and scientific pride, and to promote views subversive of all social order. But Positivism, while systematically adopting the principle here spoken of as the foundation of individual and social discipline, interprets that principle in a different way. It teaches that while it is for the heart to suggest our problems, it is for the intellect to solve them. Now the intellect was at first quite inadequate to this task, for which a long and laborious training was needed. The heart, therefore, had to take its place, and in default of objective truth, to give free play to its subjective inspirations. But for these inspirations, all progress, as I showed in my _System of Positive Philosophy_, would have been totally impossible. For a long time it was necessary that they should be believed absolutely; but as soon as our reason began to mould its conceptions upon observations, more or less accurate, of the external world, these supernatural dogmas became inevitably an obstacle to its growth. Here lies the chief source of the important modifications which theological belief has successively undergone. No further modifications are now possible without violating its essential principles; and since, meantime, Positive science is assuming every day larger proportions, the conflict between them is advancing with increasing vehemence and danger. The tendency on the one side is becoming more retrograde, on the other more revolutionary; because the impossibility of reconciling the two opposing forces is felt more and more strongly. Never was this position of affairs more manifest than now. The restoration of theology to its original power, supposing such a thing were possible, would have the most degrading influence on the intellect, and, consequently, on the character also; since it would involve the admission that our views of scientific truth were to be strained into accordance with our wishes and our wants. Therefore no important step in the progress of Humanity can now be made without totally abandoning the theological principle. The only service of any real value which it still renders, is that of forcing the attention of Western Europe, by the very fact of its reactionary tendencies, upon the greatest of all social questions.
