“Probably it is true enough that the great majority are rarely capable of thinking independently, that on most questions they accept views which they find ready-made, and that they will be equally content if born or coaxed into one set of beliefs or another. In any society freedom of thought will probably be of direct significance only for a small minority. But this does not mean that anyone is competent, or ought to have power, to select those to whom this freedom is to be reserved. It certainly does not justify the presumption of any group of people to claim the right to determine what people ought to think or believe.”
