In my books I have called it "unlearning". If you say, "This is a very nice person," and another person comes and says, "This is not a nice person, you are quite wrong," the general tendency is to stick to that idea. But the greater evolution is to see from his point-of-view also. He has a reason for it; maybe he is too unevolved to see, or he is more evolved, or less interested in the other person, or something. But by seeing from his point-of-view you do not lose your own; your own point-of-view is there. But the other point-of-view is added to yours. Therefore, your knowledge becomes greater.
