Democracy is always a beckoning goal, not a safe harbor. For freedom is an unremitting endeavor, never a final achievement.

Ultimately there can be no freedom for self unless it is vouchsafed for others; there can be no security where there is fear, and a democratic society presupposes confidence and candor in the relations of men with one another and eager collaboration for the larger ends of life instead of the pursuit of petty, selfish or vainglorious aims.
