Fourier, as we see, uses the dialectic method in the same masterly way as his contemporary Hegel. Using these same dialectics, he argues, against the talk about illimitable human perfectibility that every historical phase has its period of ascent and also its period of descent, and he applies this observation to the future of the whole human race. As Kant introduced into natural science the idea of the ultimate destruction of the earth, Fourier introduced into historical science that of the ultimate destruction of the human race. Whilst in France the hurricane of the Revolution swept over the land, in England a quieter, but not on that account less tremendous, revolution was going on. Steam and the new tool-making machinery were transforming manufacture into modern industry, and thus revolutionizing the whole foundation of bourgeois society. The sluggish march of development of the manufacturing period changed into a veritable storm and stress period of production. With constantly increasing swiftness the splitting-up of society into large capitalists and non-possessing proletarians went on. Between these, instead of the former stable middle-class, an unstable mass of artisans and small shopkeepers, the most fluctuating portion of the population, now led a precarious existence. The new mode of production was, as yet, only at the beginning of its period of ascent; as yet it was the normal, regular method of production--the only one possible under existing conditions. Nevertheless, even then it was producing crying social abuses--the herding together of a homeless population in the worst quarters of the large towns; the loosening of all traditional moral bonds, of patriarchal subordination, of family relations; overwork, especially of women and children, to a frightful extent; complete demoralization of the working-class, suddenly flung into altogether new conditions, from the country into the town, from agriculture into modern industry, from stable conditions of existence into insecure ones that changed from day to day.
