Hence all the paradox in the working-class movement. The modern worker believes, that industrial economy, the economic life itself, will of necessity evolve all that will ultimately give him his rights as man. These rights of man in full are what he is fighting for. And yet, in the heart of the fight something different makes its appearance,--something which never could be an outcome of the economic life alone. It is a significant thing, which speaks most forcibly, that here, right at the centre of the many forms which the social question assumes under the needs of human life to-day, there is something that seems, in men's belief, to proceed out of economic life, which, however, never could proceed from economic life alone,--something, that lies rather in the direct line of evolution; leading up through the old slave system, through the serfdom of the feudal age, to the modern proletariat of labour. The circulation of commodities, of money, the system of capital, property-ownership, the land system, these may have taken no matter what form under modern life; but at the heart of modern life something else has taken place, never distinctly expressed, not consciously felt even by the modern worker, but which is the fundamental force actuating all his social purpose. It is this:--The modern capitalist system of economy recognises, at bottom, nothing but commodities within its own province. It understands the creation of commodity-values as a process in the body economic. And in the capitalistic processes of the modern age something has been turned into a commodity, which the worker feels must not and cannot be a commodity. If it were only recognised what a fundamental force this is in the social movement amongst the modern workers: this loathing that the modern worker feels at being forced to barter his labour-power to the employer, as goods are bartered in the market,--loathing at seeing his personal labour-power play part as a factor in the supply and demand of the labour-market, just as the goods in the market are subject to supply and demand. When once people become aware what this loathing of the "labour-commodity" means for the modern social movement, when once they straightly and honestly recognise, that the thing at work there is not even emphatically and drastically enough expressed in socialist doctrines,--then they will have discovered the second of the two impulses which are making the social question to-day so urgent, one may indeed say so burning,--the first being that spiritual life that is felt as an ideology.
