Nature smiles at the union of freedom and equality in our utopias. For freedom and equality are sworn and everlasting enemies, and when on prevails the other dies. Leave men free, and their natural inequalities will multiply almost geometrically. To check the growth of inequality, liberty must be sacrificed, as in Russia after 1917. Even when repressed, inequality grows; only the man who is below the average in economic ability desires equality; those who are conscious of superior ability desire freedom; and in the end superior ability has its way.
So the conservative who resists change is as valuable as the radical who proposes it – perhaps as much more valuable as roots are more vital than the grafts. It is good that new ideas should be heard, for the sake of the few that can be used; but it is also good that new ideas should be compelled to go through the mill of objection, opposition, and contumely; this is the trial heat which innovations must survive before being allowed to enter the human race. It is good that the old should resist the young, and that the young should prod the old; out of this tension, as out of the strife of the sexes and the classes, comes a creative tensile strength, a stimulated development, a secret and basic unity and movement of the whole.
