Context: This country of ours has been the birthplace and the home of some of the greatest movements that have yet arisen for human freedom and human progress, and the strength of our race is not yet exhausted. We have confused ourselves in Great Britain of recent years by a curious diffidence, and by a fear of relying upon ourselves. The result has been that many of those who have been eager for the progress of our country have only succeeded in befogging themselves and their fellow-countrymen, by filling their bellies with the east wind of German Socialism and Russian Communism and French Syndicalism. Rather should they have looked deep into the hearts of their own people, relying on that common sense and political sense that has never failed our race.... [That] far from following at the tail of exploded Continental theorists, is ready once more to lead the way of the world as she was destined to do from the beginning of time, and to show other peoples, many peoples who have not yet learned what real political freedom is, that the mother of political freedom is still capable of guiding the way to her children and her children's children.
