The public is not, and never can be, identical to the people: this is true in all circumstances, everywhere. Since, on any given question, the public is composed of those self-selected persons interested in the affair, it possesses no legitimate authority whatever, and lacks the structure to enforce any authority that might fall its way. The public has no executive, no law, no jails. It can only express an opinion, in words and in actions—in its own flesh and blood.
