Pacem in Terris §34
Pacem in Terris: On Establishing Universal Peace in Truth, Justice, Charity, and Liberty
34 Man's personal dignity requires besides that he enjoy freedom and be able to make up his own mind when he acts. In his association with his fellows, therefore, there is every reason why his recognition of rights, observance of duties, and many-sided collaboration with other men, should be primarily a matter of his own personal decision. Each man should act on his own initiative, conviction, and sense of responsibility, not under the constant pressure of external coercion or enticement. There is nothing human about a society that is welded together by force. Far from encouraging, as it should, the attainment of man's progress and perfection, it is merely an obstacle to his freedom.
