Moreover, the natural development of economic antagonisms, the waking consciousness of an important fraction of the proletariat, the constantly increasing number of unemployed, the blind resistance of the ruling classes, in short contemporary evolution as a whole, is conducting us inevitably towards the outbreak of a great revolution, which will overthrow everything by its violence, and the fore-running signs of which are already visible. This revolution will happen, with us or without us; and the existence of a revolutionary party, conscious of the end to be attained, will serve to give a useful direction to the violence, and to moderate its excesses by the influence of a lofty ideal.
