The principles of the social doctrine, in their entirety, constitute that primary articulation of the truth of society by which every conscience is challenged and invited to interact with every other conscience in truth, in responsibility shared fully with all people and also regarding all people. In fact, man cannot avoid the question of freedom and of the meaning of life in society, since society is a reality that is neither external nor foreign to his being. These principles have a profoundly moral significance because they refer to the ultimate and organizational foundations of life in society. To understand them completely it is necessary to act in accordance with them, following the path of development that they indicate for a life worthy of man. The ethical requirement inherent in these pre-eminent social principles concerns both the personal behaviour of individuals — in that they are the first and indispensable responsible subjects of social life at every level — and at the same time institutions represented by laws, customary norms and civil constructs, because of their capacity to influence and condition the choices of many people over a long period of time. In fact, these principles remind us that the origins of a society existing in history are found in the interconnectedness of the freedoms of all the persons who interact within it, contributing by means of their choices either to build it up or to impoverish it.
