The words “belief” and “faith” must not be misunderstood. In the “reorganisation of beliefs” which he undertakes, Comte only concerns himself with beliefs capable of demonstration. He is here faithful to the thought of Saint Simon, who understood “religion” chiefly as a basis of political organisation. At any rate, in the early part of his philosophical career Comte does not bring into “faith” the mystical, sentimental and non-intellectual elements which this word usually implies and which so often oppose it to “reason.” The word signifies for Comte that which man believes concerning _what may be for him a subject of knowledge_. Until now these beliefs have set forth a more or less mythical or metaphysical explanation of the universe and of man, taught by priests and philosophers. But this no longer satisfies the human mind. By degrees positive science, which works on a totally different plan, substitutes a knowledge of the laws of phenomena to those “explanations.” From this moment the problem thus presents itself to Comte: To establish by rational means a system of universally accepted truths concerning man, society and the world. Comte thus takes for granted: 1st, that the “opinions,” the “beliefs” and the “conceptions” relating to these matters, are to-day “anarchical”: 2nd, that their natural and normal condition is to be “organised.” There is no need to prove the first part; a glance at contemporary society is enough. The confused disturbing movements which fill it with trouble and agitation, and which, unless rational harmony be at last established, threaten its destruction are not due merely to political causes. They proceed from moral disorder. And this in turn proceeds from intellectual disorder, that is to say from a lack of principles common to all minds, and from the absence of universally admitted conceptions and beliefs. For in order that a human society may subsist, a certain harmony of sentiment or even common interests among its members will not suffice. Above all things, intellectual concord which finds expression in a body of common beliefs is necessary.
