The political movement known as Socialism is, perhaps, even less realized by the general public. The great strides it has taken and the portentous front it today exhibits are not comprehended; and, fastened though it is in every land, it is given little space by the capitalistic press. For all its plea and passion and warmth, it wells upward like a great, cold tidal wave, irresistible, inexorable, ingulfing present-day society level by level. By its own preachment it is inexorable. Just as societies have sprung into existence, fulfilled their function, and passed away, it claims, just as surely is present society hastening on to its dissolution. This is a transition period--and destined to be a very short one. Barely a century old, capitalism is ripening so rapidly that it can never live to see a second birthday. There is no hope for it, the Socialists say. It is doomed. The cardinal tenet of Socialism is that forbidding doctrine, the materialistic conception of history. Men are not the masters of their souls. They are the puppets of great, blind forces. The lives they live and the deaths they die are compulsory. All social codes are but the reflexes of existing economic conditions, plus certain survivals of past economic conditions. The institutions men build they are compelled to build. Economic laws determine at any given time what these institutions shall be, how long they shall operate, and by what they shall be replaced. And so, through the economic process, the Socialist preaches the ripening of the capitalistic society and the coming of the new cooperative society. The second great tenet of Socialism, itself a phase of the materialistic conception of history, is the class struggle. In the social struggle for existence, men are forced into classes. "The history of all society thus far is the history of class strife." In existing society the capitalist class exploits the working class, the proletariat. The interests of the exploiter are not the interests of the exploited. "Profits are legitimate," says the one. "Profits are unpaid wages," replies the other, when he has become conscious of his class, "therefore profits are robbery." The capitalist enforces his profits because he is the legal owner of all the means of production. He is the legal owner because he controls the political machinery of society. The Socialist sets to work to capture the political machinery, so that he may make illegal the capitalist's ownership of the means of production, and make legal his own ownership of the means of production. And it is this struggle, between these two classes, upon which the world has at last entered.
