From Pope St. John Paul II’s encyclical Fides et Ratio (1984):
It should also be borne in mind that the role of philosophy itself has changed in modern culture. From universal wisdom and learning, it has been gradually reduced to one of the many fields of human knowing; indeed in some ways it has been consigned to a wholly marginal role. Other forms of rationality have acquired an ever higher profile, making philosophical learning appear all the more peripheral. These forms of rationality are directed not towards the contemplation of truth and the search for the ultimate goal and meaning of life; but instead, as “instrumental reason”, they are directed—actually or potentially—towards the promotion of utilitarian ends, towards enjoyment or power.
In my first Encyclical Letter I stressed the danger of absolutizing such an approach when I wrote: “The man of today seems ever to be under threat from what he produces, that is to say from the result of the work of his hands and, even more so, of the work of his intellect and the tendencies of his will. All too soon, and often in an unforeseeable way, what this manifold activity of man yields is not only subject to ‘alienation’, in the sense that it is simply taken away from the person who produces it, but rather it turns against man himself, at least in part, through the indirect consequences of its effects returning on himself. It is or can be directed against him. This seems to make up the main chapter of the drama of present-day human existence in its broadest and universal dimension. Man therefore lives increasingly in fear. He is afraid of what he produces—not all of it, of course, or even most of it, but part of it and precisely that part that contains a special share of his genius and initiative—can radically turn against himself”.53
In the wake of these cultural shifts, some philosophers have abandoned the search for truth in itself and made their sole aim the attainment of a subjective certainty or a pragmatic sense of utility. This in turn has obscured the true dignity of reason, which is no longer equipped to know the truth and to seek the absolute.
