Here is the Pope’s definition of truth, playing on the Greek expression for the Word (of God): “Truth, in fact, is lógos which creates diá-logos, and hence communication and communion.” Truth requires communication with others’ truth. The very next sentence explains what he means by communication, namely if a person is not willing to let go of his personal opinions, he cannot have the truth: “Truth, by enabling men and women to let go of their subjective opinions and impressions, allows them to move beyond cultural and historical limitations and to come together in the assessment of the value and substance of things” (§4). Without such a sharing with others there is no truth, for man is isolated in his “subjective opinions.” (Fr. Scott, "HUMANIST MANIFESTO: A commentary on the encyclical Caritas in veritate")
I have suggested in the past that those who seek to know the origin of Benedict's (and many other bishops', particularly Cardinal Kasper) foreign concept of "dialogue" must look to the writings of hasidic philosopher Martin Buber (and the Bal Shem Tov and other kabbalists Buber's thinking was derived from), who Benedict and Kasper have both plainly said is a major influence.

Walter Kasper's Mentor: Hassidic Philosopher, Martin Buber
The Dialogical Path Towards Disaster
The Gospel tells us Jesus taught as one having authority. The Truths of Jesus' teachings weren't arrived at through 'dialogue' with Pharisees as a means of "moving beyond cultural and historical limitations." Neither do we see such an example in the Apostles or the Church fathers. Benedict is preaching an anti-Gospel. He's claiming a "sacred" mandate to get us seated at the table with the lawyers so that they can defraud us with their word magic. There is no example for "sacred dialogue" in the Church canon. Beware these hasidic teachings of Benedict XVI. They lead to ruin.
