This is the real secret of the terror inspired by an original thinker. In repudiating convention he is repudiating that on which his neighbors are relying for their sense of security. But he is usually also doing something even more unpopular. He is proposing new obligations to add to the already heavy burden of duty. When the boy Shelley elaborately and solemnly cursed his father for the entertainment of his friends, he only shocked us. But when the man Shelley told us that we should feed, clothe and educate all the children in the country as carefully as if they were our immediate own, we lost our tempers with him and deprived him of the custody of his own children. It is useless to complain that the conventional masses are unintelligent. To begin with, they are not unintelligent except in the sense in which all men are unintelligent in matters in which they are not experts. I object to be called unintelligent merely because I do not know enough about mechanical construction to be able to judge whether a motor car of new design is an improvement or not, and therefore prefer to buy one of the old type to which I am accustomed. The brave bourgeois whom Brieux scandalizes must not be dismissed with ridicule by the man of letters because, not being an expert in morals, he prefers the old ways and mistrusts the new. His position is a very reasonable one. He says, in effect, ‘If I am to enjoy any sense of security, I must be able to reckon on other people behaving in a certain ascertained way. Never mind whether it is the ideally right way or the ideally wrong way: it will suit me well enough if only it is convenient and, above all, unmistakeable. Lay it down if you like that people are not to pay debts and are to murder one another whenever they get a chance. In that case I can refuse to give credit and can carry weapons and learn to use them to defend myself. On the other hand, if you settle that debts are to be enforced and the peace kept by the police, I will give credit and renounce the practice of arms. But the one thing that I cannot stand is not knowing what the social contract is.’ The Justification of Conventionality.
