George Bernard Shaw Quote
The last word remains with Christ and Handel; and this must stand as the best defence of Tolerance until a better man than I makes a better job of it.
Put shortly and undramatically the case is that a civilization cannot progress without criticism, and must therefore, to save itself from stagnation and putrefaction, declare impunity for criticism. This means impunity not only for propositions which, however novel, seem interesting, statesmanlike, and respectable, but for propositions that shock the uncritical as obscene, seditious, blasphemous, heretical, and revolutionary.
