To refuse a hearing to an opinion, because they are sure that it is false, is to assume that their certainty is the same thing as absolute certainty. All silencing of discussion is an assumption of infallibility.

A democratic constitution, not supported by democratic institutions in detail, but confined to the central government, not only is not political freedom, but often creates a spirit precisely the reverse, carrying down to the lowest grade in society the desire and ambition of political domination.

Not only the grounds of the opinion are forgotten in the absence of discussion, but too often the meaning of the opinion itself... Instead of a vivid conception and a living belief, there remain only a few phrases retained by rote; or, if any part, the shell and husk only of the meaning is retained, the finer essence being lost.

Laws and systems of polity always begin by recognizing the relations they find already existing between individuals.
