“Justice is primarily a possible, but not a necessary, quality of a social order regulating the mutual relations of men. Only secondarily it is a virtue of man, since a man is just, if his behavior conforms to the norms of a social order supposed to be just. But what does it really mean to say that a social order is just? It means that this order regulates the behavior of men in a way satisfactory to all men, that is to say, so that all men find their happiness in it. The longing for justice is men's eternal longing for happiness. It is happiness that men cannot find alone, as an isolated individual, and hence seeks in society. Justice is social happiness. It is happiness guaranteed by a social order.”

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: Every system which endeavours, either, by extraordinary encouragements, to draw towards a particular species of industry a greater share of the capital of the society than what would naturally go to it; or, by extraordinary restraints, to force from a particular species of industry some share of the capital which would otherwise be employed in it; is in reality subversive of the great purpose which it means to promote. It retards, instead of accelerating, the progress of the society towards real wealth and greatness; and diminishes, instead of increasing, the real value of the annual produce of its land and labour.
All systems either of preference or of restraint, therefore, being thus completely taken away, the obvious and simple system of natural liberty establishes itself of its own accord. Every man, as long as he does not violate the laws of justice, is left perfectly free to pursue his own interest his own way, and to bring both his industry and capital into competition with those of any other man, or order of men. The sovereign is completely discharged from a duty, in the attempting to perform which he must always be exposed to innumerable delusions, and for the proper performance of which no human wisdom or knowledge could ever be sufficient; the duty of superintending the industry of private people, and of directing it towards the employments most suitable to the interest of the society. According to the system of natural liberty, the sovereign has only three duties to attend to; three duties of great importance, indeed, but plain and intelligible to common understandings: first, the duty of protecting the society from the violence and invasion of other independent societies; secondly, the duty of protecting, as far as possible, every member of the society from the injustice or oppression of every other member of it, or the duty of establishing an exact administration of justice; and, thirdly, the duty of erecting and maintaining certain public works and certain public institutions, which it can never be for the interest of any individual, or small number of individuals, to erect and maintain; because the profit could never repay the expence to any individual, or small number of individuals, though it may frequently do much more than repay it to a great society.
The proper performance of those several duties of the sovereign necessarily supposes a certain expence; and this expence again necessarily requires a certain revenue to support it.

Ten Sermons of Religion (1853), III : Of Justice and the Conscience https://en.wikisource.org/wiki/Ten_Sermons_of_Religion/Of_Justice_and_the_Conscience
Context: Justice is moral temperance in the world of men. It keeps just relations between men; one man, however little, must not be sacrificed to another, however great, to a majority, or to all men. It holds the balance betwixt nation and nation, for a nation is but a larger man; betwixt a man and his family, tribe, nation, race; between mankind and God. It is the universal regulator which coordinates man with man, each with all, — me with the ten hundred millions of men, so that my absolute rights and theirs do not interfere, nor our ultimate interests ever clash, nor my eternal welfare prove antagonistic to the blessedness of all or any one. I am to do justice, and demand that of all, — a universal human debt, a universal human claim.
