"OF all the tests by which the good citizen and strong reformer can be distinguished from the vague faddist or the inhuman sceptic, I know no better test than this -- that the unreal reformer sees in front of him one certain future, the future of his fad; while the real reformer sees before him ten or twenty futures among which his country must choose, and may in some dreadful hour choose the wrong one. The true patriot is always doubtful of victory; because he knows that he is dealing with a living thing; a thing with free will. To be certain of free will is to be uncertain of success."
~G.K. Chesterton: Introduction to American Notes by Charles Dickens.
