5 It is, however, especially necessary that all parties concerned should adopt for themselves a proper moral outlook on the use of these media, especially with respect to certain questions that have been vigorously aired in our day. The first question has to do with "information," as it is called, or the search for and reporting of the news. Now clearly this has become most useful and very often necessary for the progress of contemporary society and for achieving closer links among men. The prompt publication of affairs and events provides every individual with a fuller, continuing acquaintance with them, and thus all can contribute more effectively to the common good and more readily promote and advance the welfare of the entire civil society. Therefore, in society men have a right to information, in accord with the circumstances in each case, about matters concerning individuals or the community. The proper exercise of this right demands, however, that the news itself that is communicated should always be true and complete, within the bounds of justice and charity. In addition, the manner in which the news is communicated should be proper and decent. This means that in both the search for news and in reporting it, there must be full respect for the laws of morality and for the legitimate rights and dignity of the individual. For not all knowledge is helpful, but "it is charity that edifies."
