“In that case the current orthodoxy happens to be challenged, and so the principle of free speech lapses. Now, when one demands liberty of speech and of the press, one is not demanding absolute liberty. There always must be, or at any rate there always will be, some degree of censorship, so long as organised societies endure. But freedom, as Rosa Luxembourg [sic] said, is ‘freedom for the other fellow’. The same principle is contained in the famous words of Voltaire: ‘I detest what you say; I will defend to the death your right to say it.’ If the intellectual liberty which without a doubt has been one of the distinguishing marks of western civilisation means anything at all, it means that everyone shall have the right to say and to print what he believes to be the truth, provided only that it does not harm the rest of the community in some quite unmistakable way.”
