Pope John XXIII
Pacem in Terris §12
Rights Pertaining to Moral and Cultural Values
12 Moreover, man has a natural right to be respected. He has a right to his good name. He has a right to freedom in investigating the truth, and—within the limits of the moral order and the common good—to freedom of speech and publication, and to freedom to pursue whatever profession he may choose. He has the right, also, to be accurately informed about public events.
