We must face the fact that society is founded on intolerance. [. . .] We may prate of toleration as we will; but society must always draw a line somewhere between allowable conduct and insanity or crime, in spite of the risk of mistaking sages for lunatics and saviours for blasphemers. We must persecute, even to the death; and all we can do to mitigate the danger of persecution is, first, to be very careful what we persecute, and second, to bear in mind that unless there is a large liberty to shock conventional people, and a well informed sense of the value of originality, individuality, and eccentricity, the result will be apparent stagnation covering a repression of evolutionary forces which will eventually explode with extravagant and probably destructive violence.
