inherent conditions, stimulated and made to grow like a giant, is the only heritage of past centuries which communism accepts and adopts without reserve. It would not be useful to stop here for the discussion of the so-called antithesis between science and philosophy. If we accept those fashions of philosophizing which are confounded with mysticism and theology, philosophy never means a science or doctrine separate from its appropriate and particular things, but it is simply a degree, a form, a stage of thought with relation to the things which enter into the domain of experience. Philosophy is, then, either a generic anticipation of the problems which science has still to elaborate specifically, or a summary and a conceptual elaboration of the results at which the sciences have already arrived. As for those who, that they may not appear behind the times, talk now of scientific philosophy, if we do not wish to stop over the humorous element that there is in that expression, it will suffice to say that they are simply fools. I said some pages back, in my statement of formulas, that the economic structure determines in the second place the direction, and in great part and indirectly, the objects of imagination and of thought in the production of art, of religion and of science. To express this otherwise, or to go further, would be to put one's self voluntarily on the road toward the absurd. Before all else, in this formula, we are opposing the fantastic opinion, that art, religion and science are subjective developments and historical developments of a pretended artistic, religious or scientific spirit, which would go on manifesting itself successively through its own rhythm of evolution, favored or retarded on this side or that by material conditions. By this formula, it is desired to assert, moreover, the necessary connection, through which every fact of art and of religion is the exponent, sentimental, fantastic and thus derived, of definite social conditions. If I say _in the second place_, it is to distinguish these products from the facts of legal-political order which are a true and proper projection of economic conditions. And if I say _in great part and indirectly the objects_ of these activities, it is to indicate two things: that in artistic or religious production the mediation from the conditions to the products is very complicated, and again that men, while living in society, do not thereby cease to live alone by themselves in nature, and to receive from it occasion and material for curiosity and for imagination.
