Doubtless all knowledge brings up at last against a mystery: such, for instance, as matter and mind, both of which we admit as two unknown essences, upon which all phenomena rest. But this is not to say that mystery is the point of departure of knowledge, or that mysticism is the necessary condition of logic: quite the contrary, the spontaneity of our reason tends to the perpetual rejection of mysticism; it makes an a priori protest against all mystery, because it has no use for mystery except to deny it, and because the negation of mysticism is the only thing for which reason has no need of experience. In short, human facts are the incarnation of human ideas: therefore, to study the laws of social economy is to constitute the theory of the laws of reason and create philosophy. We may now pursue the course of our investigation. At the end of the preceding chapter we left the laborer at loggerheads with the law of division: how will this indefatigable Oedipus manage to solve this enigma? In society the incessant appearance of machinery is the antithesis, the inverse formula, of the division of labor; it is the protest of the industrial genius against parcellaire and homicidal labor. What is a machine, in fact? A method of reuniting divers particles of labor which division had separated. Every machine may be defined as a summary of several operations, a simplification of powers, a condensation of labor, a reduction of costs. In all these respects machinery is the counterpart of division. Therefore through machinery will come a restoration of the parcellaire laborer, a decrease of toil for the workman, a fall in the price of his product, a movement in the relation of values, progress towards new discoveries, advancement of the general welfare. As the discovery of a formula gives a new power to the geometer, so the invention of a machine is an abridgment of manual labor which multiplies the power of the producer, from which it may be inferred that the antinomy of the division of labor, if not entirely destroyed, will be balanced and neutralized. No one should fail to read the lectures of M. Chevalier setting forth the innumerable advantages resulting to society from the intervention of machinery; they make a striking picture to which I take pleasure in referring my reader.
