"The truth is a desire of the human person, the search for which always supposes the exercise of authentic freedom. Many, however, prefer shortcuts, trying to avoid this task. Some, like Pontius Pilate, ironically question the possibility of even knowing what truth is (cf. Jn 18:38), proclaiming that man is incapable of knowing it or denying that there exists a truth valid for all. This attitude, as in the case of scepticism and relativism, changes hearts, making them cold, wavering, distant from others and closed. They, like the Roman governor, wash their hands and let the water of history drain away without taking a stand.Special note for me is the parallel that he draws between Pontius Pilate and the refusal to find the truth by declaring that it's impossible to know. His criticism is directed towards giving up the search itself. Truth might not be easy to find or easy to accept but it should not be left alone.
On the other hand, there are those who wrongly interpret this search for the truth, leading them to irrationality and fanaticism; they close themselves up in “their truth”, and try to impose it on others. These are like the blind scribes who, upon seeing Jesus beaten and bloody, cry out furiously, “Crucify him!” (cf. Jn 19:6). Anyone who acts irrationally cannot become a disciple of Jesus. Faith and reason are necessary and complementary in the pursuit of truth. God created man with an innate vocation to the truth and he gave him reason for this purpose. Certainly, it is not irrationality but rather the yearning for truth which the Christian faith promotes. Each human being has to seek the truth and to choose it when he or she finds it, even at the risk of embracing sacrifices.
Furthermore, the truth which stands above humanity is an unavoidable condition for attaining freedom, since in it we discover the foundation of an ethics on which all can converge and which contains clear and precise indications concerning life and death, duties and rights, marriage, family and society, in short, regarding the inviolable dignity of the human person. This ethical patrimony can bring together different cultures, peoples and religions, authorities and citizens, citizens among themselves, and believers in Christ and non-believers.
Christianity, in highlighting those values which sustain ethics, does not impose, but rather proposes Christ’s invitation to know the truth which sets us free. The believer is called to offer that truth to his contemporaries, as did the Lord, even before the dark omen of rejection and the Cross. The personal encounter with the one who is Truth in person compels us to share this treasure with others, especially by our witness."

How faith and reason are required for truth
This is a long quote from another page. It's worth reading the whole thing, though. If you don't have time, just read this part.
