The case for the view that freedom of thought and speech is a good in itself is fairly easy to make. If it is the business of those who exercise authority in the state to satisfy the wants of those over whom they rule, it is plain that they should be informed of those wants; and, obviously, they cannot be truly informed about them unless the mass of men is free to report their experience. No state, for instance, could rightly legislate about the hours of labour if only business men were free to offer their opinion upon industrial conditions. We could not develop an adequate law of divorce if only those happily married were entitled to express an opinion upon its terms. Law must take account of the totality of experience and this can only be known to it as that experience is unfettered in its opportunity of expression. Most people are prepared to agree with this view when it is made as a general statement; most people, also, recoil from it when its implications are made fully known. For it implies not only the right to beatify the present social order, but the right, also, to condemn it with vigour and completeness. A man may say that England or America will never be genuinely democratic unless equality of income is established there; that equality of income may never be established except by force; that, accordingly, the way to a genuine democracy lies through a bloody revolution. Or he may argue that eternal truth is the sole possession of the Roman Catholic Church; that men can only be persuaded to understand this by the methods of the Inquisition; that, therefore, the re-establishment of the Inquisition is in the highest interest of society. To most of us, these views will seem utterly abhorrent. Yet they represent the generalizations of an experience that some one has felt. They point to needs which are seeking satisfaction, and the society gains nothing by prohibiting their expression.
