Good remarks and a fine prayer yesterday from Pope Francis on "fake news" and our pursuit of truth.  An excerpt:

Freedom from falsehood and the search for relationship: these two ingredients cannot be lacking if our words and gestures are to be true, authentic, and trustworthy. To discern the truth, we need to discern everything that encourages communion and promotes goodness from whatever instead tends to isolate, divide, and oppose. Truth, therefore, is not really grasped when it is imposed from without as something impersonal, but only when it flows from free relationships between persons, from listening to one another. Nor can we ever stop seeking the truth, because falsehood can always creep in, even when we state things that are true. An impeccable argument can indeed rest on undeniable facts, but if it is used to hurt another and to discredit that person in the eyes of others, however correct it may appear, it is not truthful. We can recognize the truth of statements from their fruits: whether they provoke quarrels, foment division, encourage resignation; or, on the other hand, they promote informed and mature reflection leading to constructive dialogue and fruitful results.
