701 When we want to correct someone usefully and show him he is wrong, we must see from what point of view he is approaching the matter, for it is usually right from that point of view, and we must admit this, but show him the point of view from which it is wrong. This will please him, because he will see that he was not wrong but merely failed to see every aspect of the question. Now, no one is annoyed at not seeing everything, but no one wants to be wrong; the reason for that may be that man is not by nature able to see everything, and by nature cannot be wrong from the point of view he adopts, as sense impressions are always true.
