" The main lesson which the true liberal must learn from the success of the socialists is that it was their courage to be Utopian which gained them the support of the intellectuals and therefore an influence on public opinion which is daily making possible what only recently seemed utterly remote. Those who have concerned themselves exclusively with what seemed practicable in the existing state of opinion have constantly found that even this had rapidly become politically impossible as the result of changes in a public opinion which they have done nothing to guide. "
