"The mere possession of power tends to produce a love of power, which is a very dangerous motive, because the only sure proof of power consists in preventing others from doing what they wish to do. The essential theory of democracy is the diffusion of power among the whole people, so that the evils produced by one man's possession of great power shall be obviated. But the diffusion of power through democracy is only effective when the voters take an interest in the question involved. When the question does not interest them, they do not attempt to control the administration, and all actual power passes into the hands of officials."
