From Pope St. John Paul II’s encyclical Fides et Ratio (1984):
The importance of metaphysics becomes still more evident if we consider current developments in hermeneutics and the analysis of language. The results of such studies can be very helpful for the understanding of faith, since they bring to light the structure of our thought and speech and the meaning which language bears. However, some scholars working in these fields tend to stop short at the question of how reality is understood and expressed, without going further to see whether reason can discover its essence. How can we fail to see in such a frame of mind the confirmation of our present crisis of confidence in the powers of reason? When, on the basis of preconceived assumptions, these positions tend to obscure the contents of faith or to deny their universal validity, then not only do they abase reason but in so doing they also disqualify themselves. Faith clearly presupposes that human language is capable of expressing divine and transcendent reality in a universal way—analogically, it is true, but no less meaningfully for that.103 Were this not so, the word of God, which is always a divine word in human language, would not be capable of saying anything about God. The interpretation of this word cannot merely keep referring us to one interpretation after another, without ever leading us to a statement which is simply true; otherwise there would be no Revelation of God, but only the expression of human notions about God and about what God presumably thinks of us.
I am well aware that these requirements which the word of God imposes upon philosophy may seem daunting to many people involved in philosophical research today. Yet this is why, taking up what has been taught repeatedly by the Popes for several generations and reaffirmed by the Second Vatican Council itself, I wish to reaffirm strongly the conviction that the human being can come to a unified and organic vision of knowledge. This is one of the tasks which Christian thought will have to take up through the next millennium of the Christian era. The segmentation of knowledge, with its splintered approach to truth and consequent fragmentation of meaning, keeps people today from coming to an interior unity. How could the Church not be concerned by this? It is the Gospel which imposes this sapiential task directly upon her Pastors, and they cannot shrink from their duty to undertake it.
I believe that those philosophers who wish to respond today to the demands which the word of God makes on human thinking should develop their thought on the basis of these postulates and in organic continuity with the great tradition which, beginning with the ancients, passes through the Fathers of the Church and the masters of Scholasticism and includes the fundamental achievements of modern and contemporary thought. If philosophers can take their place within this tradition and draw their inspiration from it, they will certainly not fail to respect philosophy’s demand for autonomy.
In the present situation, therefore, it is most significant that some philosophers are promoting a recovery of the determining role of this tradition for a right approach to knowledge. The appeal to tradition is not a mere remembrance of the past; it involves rather the recognition of a cultural heritage which belongs to all of humanity. Indeed it may be said that it is we who belong to the tradition and that it is not ours to dispose of at will. Precisely by being rooted in the tradition will we be able today to develop for the future an original, new and constructive mode of thinking. This same appeal is all the more valid for theology. Not only because theology has the living Tradition of the Church as its original source,104 but also because, in virtue of this, it must be able to recover both the profound theological tradition of earlier times and the enduring tradition of that philosophy which by dint of its authentic wisdom can transcend the boundaries of space and time.
