Here are a few quotations, borrowed from the brainyquote site, from Robert Frost concerning politics (and in one case, law):
A liberal is a man too broadminded to take his own side in a quarrel.
If society fits you comfortably enough, you call it freedom.
Poetry is about the grief. Politics is about the grievance.
The only certain freedom’s in departure.
The strongest and most effective force in guaranteeing the long-term maintenance of power is not violence in all the forms deployed by the dominant to control the dominated, but consent in all the forms in which the dominated acquiesce in their own domination.
Thinking isn’t agreeing or disagreeing. That’s voting.
A jury consists of twelve persons chosen to decide who has the better lawyer.
