In the course of social evolution there are developed individuals so constituted as not to fit existing conditions, but to be organically adapted to more advanced conditions. These advanced individuals respond in sharp and painful consciousness to existing conditions, and cry out against them according to their lights. The history of religion, of political and social reform, is full of familiar instances of this. The heretic, the reformer, the agitator, these feel what their compeers do not, see what they do not, and, naturally, say what they do not. The mass of the people are invariably displeased by the outcry of these uneasy spirits. In simple primitive periods they were promptly put to death. Progress was slow and difficult in those days. But this severe process of elimination developed the kind of progressive person known as a martyr; and this remarkable sociological law was manifested: that the strength of a current of social force is increased by the sacrifice of individuals who are willing to die in the effort to promote it. “The blood of the martyrs is the seed of the church.” This is so commonly known to-day, though not formulated, that power hesitates to persecute, lest it intensify the undesirable heresy. A policy of “free speech” is found to let pass most of the uneasy pushes and spurts of these stirring forces, and lead to more orderly action. Our great anti-slavery agitation, the heroic efforts of the “women’s rights” supporters, are fresh and recent proofs of these plain facts: that the mass of the people do not notice existing conditions, and that they are not pleased with those who do. This is one strong reason why the sexuo-economic relation passes unobserved among us, and why any statement of it will be so offensive to many.
