In other words, our aim must be to evolve a social order in which the sense of freedom and the sense of responsibility are both carried to the highest point, and that is impossible by the aid of measures which are only beneficial for the children of Perdition. That there are such beings, incapable alike either of freedom or of responsibility, we have to recognise. It is our business to care for them--until with the help of eugenics we can in some degree extinguish their stocks--in such refuges and reformatories as may be found desirable. But it is not our business to treat the whole world as a refuge and a reformatory. That is fatal to human freedom and fatal to human responsibility. By all means provide the halt and the lame with crutches. But do not insist that the sound and the robust shall never stir abroad without crutches. The result will only be that we shall all become more or less halt and lame. It is only by such a method as this--by segregating the hopelessly feeble members of society and by allowing the others to take all the risks of their freedom and responsibility even though we strongly disapprove--that we can look for the coming of a better world. It is only by such a method as this that we can afford to give scope to all those varying and ever-contradictory activities which go to the making of any world worth living in. For Conflict, even the conflict of ideals, is a part of all vital progress, and each party to the conflict needs free play if that conflict is to yield us any profit. That is why Masculinists have no right to impede the play of Feminism, and Feminists no right to impede the play of Masculinism. The fundamental qualities of Man, equally with the fundamental qualities of Woman, are for ever needed in any harmonious civilisation. There is a place for Masculinism as well as a place for Feminism. From the highest standpoint there is not really any conflict at all. They alike serve the large cause of Humanity, which equally includes them both. [1] "Wuerdelose Weiber," _Die Neue Generation_, Aug.-Sept., 1914.
