Of one man in especial, beyond anyone else, the citizens of a republic should beware, and that is of the man who appeals to them to support him on the ground that he is hostile to other citizens of the republic, that he will secure for those who elect him, in one shape or another, profit at the expense of other citizens of the republic. It makes no difference whether he appeals to class hatred or class interest, to religious or anti-religious prejudice. The man who makes such an appeal should always be presumed to make it for the sake of furthering his own interest.
