“…all men naturally love freedom, however ignorant they may be of that eternal vigilance and the necessary measures to preserve it, and where their folly has caused them to lose it, always try to return to it.”

Address to the United Nations (1963)
Context: The Charter of the United Nations expresses the noblest aspirations of man: abjugation of force in the settlement of disputes between states; the assurance of human rights and fundamental freedoms for all without distinction as to race, sex, language or religion; the safeguarding of international peace and security.
But these, too, as were the phrases of the Covenant, are only words; their value depends wholly on our will to observe and honour them and give them content and meaning. The preservation of peace and the guaranteeing of man's basic freedoms and rights require courage and eternal vigilance: courage to speak and act — and if necessary, to suffer and die — for truth and justice; eternal vigilance, that the least transgression of international morality shall not go undetected and unremedied.
These lessons must be learned anew by each succeeding generation, and that generation is fortunate indeed which learns from other than its own bitter experience. This Organization and each of its members bear a crushing and awesome responsibility: to absorb the wisdom of history and to apply it to the problems of the present, in order that future generations may be born, and live, and die, in peace.

Variant translation: Trade is the natural enemy of all violent passions. Trade loves moderation, delights in compromise, and is most careful to avoid anger. It is patient, supple, and insinuating, only resorting to extreme measures in cases of absolute necessity. Trade makes men independent of one another and gives them a high idea of their personal importance: it leads them to want to manage their own affairs and teaches them to succeed therein. Hence it makes them inclined to liberty but disinclined to revolution.
