It had never occurred to me, as a general moral principle, that two educated men were for ever forbidden to talk sense about a particular topic, because a lot of other people had already voted on it. What is the matter with that attitude is the loss of the freedom of the mind. There can be no liberty of thought unless it is ready to unsettle what has recently been settled, as well as what has long been settled. We are perpetually being told in the papers that what is wanted is a strong man who will do things. What is wanted is a strong man who will undo things; and that will be a real test of strength.
