“Justice, like liberty and coercion, is a concept which, for the sake of clarity, ought to be confined to the deliberate treatment of men by other men.”

The History of Freedom in Antiquity (1877)
Context: But it may be urged, on the other side, that Liberty is not the sum or substitute for of all things men ought to live for... to be real it must be circumscribed... advancing civilisation invests the state with increased rights and duties, and imposes increased burdens and constraints on the subject... a highly instructed and intelligent community may perceive the benefit of compulsory obligations which, at a lower stage, would be thought unbearable... liberal progress is not vague or indefinite, but aims at a point where the public is subject to no restrictions but those of which it feels the advantage... a free country may be less capable of doing much for the advancement of religion, the prevention of vice, or the relief of suffering, than one that does not shrink from confronting great emergencies by some sacrifice of individual rights, and some concentration of power... the supreme political object ought to be sometimes postponed to still higher moral objects. My argument involves no collision with these qualifying reflections. We are dealing, not with the effects of freedom, but with its causes.... influences which brought arbitrary government under control, either by the diffusion of power, or to an appeal to an authority which transcends all government, and among these influences the greatest philosophers of Greece have no claim to be reckoned.

1963, Address in the Assembly Hall at the Paulskirche in Frankfurt
Context: The mission is to create a new social order, rounded on liberty and justice, in which men are the masters of their fate, in which states are the servants of their citizens, and in which all men and women can share a better life for themselves and their children. That is the object of our common policy. To realize this vision, we must seek a world of peace — a world in which peoples dwell together in mutual respect and work together in mutual regard — a world where peace is not a mere interlude between wars, but an incentive to the creative energies of humanity. We will not find such a peace today, or even tomorrow. The obstacles to hope are large and menacing. Yet the goal of a peaceful world — today and tomorrow-must shape our decisions and inspire our purposes. So we are all idealists. We are all visionaries. Let it not be said of this Atlantic generation that we left ideals and visions to the past, nor purpose and determination to our adversaries. We have come too far, we have sacrificed too much, to disdain the future now. And we shall ever remember what Goethe told us — that the "highest wisdom, the best that mankind ever knew" was the realization that "he only earns his freedom and existence who daily conquers them anew."

Context: What do we mean when we say that first of all we seek liberty? I often wonder whether we do not rest our hopes too much upon constitutions, upon laws and upon courts. These are false hopes; believe me, these are false hopes. Liberty lies in the hearts of men and women; when it dies there, no constitution, no law, no court can save it; no constitution, no law, no court can even do much to help it… What is this liberty that must lie in the hearts of men and women? It is not the ruthless, the unbridled will; it is not the freedom to do as one likes. That is the denial of liberty and leads straight to its overthrow. A society in which men recognize no check on their freedom soon becomes a society where freedom is the possession of only a savage few — as we have learned to our sorrow.
What then is the spirit of liberty? I cannot define it; I can only tell you my own faith. The spirit of liberty is the spirit which is not too sure that it is right; the spirit of liberty is the spirit which seeks to understand the minds of other men and women; the spirit of liberty is the spirit which weighs their interests alongside its own without bias; the spirit of liberty remembers that not even a sparrow falls to earth unheeded; the spirit of liberty is the spirit of Him who, near two thousand years ago, taught mankind that lesson it has never learned, but has never quite forgotten; that there may be a kingdom where the least shall be heard and considered side by side with the greatest.

Original: (fr) La vertu suppose la liberté, comme le transport d’un fardeau suppose la force active. Dans la contrainte point de vertu, et sans vertu point de religion. Rends-moi esclave, je n’en serai pas meilleur. Le souverain même n’a aucun droit d’employer la contrainte pour amener les hommes à la religion, qui suppose essentiellement choix et liberté. Ma pensée n’est pas plus soumise à l’autorité que la maladie ou la santé.
