Media of social communication

20. Among the major changes of our times, we do not wish to forget to emphasize the growing role being assumed by the media of social communication and their influence on the transformation of mentalities of knowledge, of organizations and of society itself. Certainly they have many positive aspects. Thanks to them news from the entire world reaches us practically in an instant, establishing contacts which supersede distances and creating elements of unity among all men. A greater spread of education and culture is becoming possible. Nevertheless, by their very action the media of social communication are reaching the point of representing as it were a new power. One cannot but ask about those who really hold this power, the aims that they pursue and the means they use, and finally, about the effect of their activity on the exercise of individual liberty, both in the political and ideological spheres and in social, economic and cultural life. The men who hold this power have a grave moral responsibility with respect to the truth of the information that they spread, the needs and the reactions that they generate and the values which they put forward. In the case of television, moreover, what is coming into being is an original mode of knowledge
and a new civilization: that of the image.

Naturally, the public authorities cannot ignore the growing power and influence of the media of social communication and the advantages and risks which their use involves for the civic community and for its development and real perfecting.

Consequently they are called upon to perform their own positive function for the common good by encouraging every constructive expression, by supporting individual citizens and groups in defending the fundamental values of the person and of human society, and also by taking suitable steps to prevent the spread of what would harm the common heritage of values on which orderly civil progress is based ¹⁵.
