I remember John Major, (who could well turn out to be the last Conservative Prime Minister of Britain in more senses than one), when he was the minister in charge of things to do with Law and Order ("Home Secretary"), made a speech in which he declared that what was needed was "To understand less and to condemn more".

I think most people agree that it wasn't really a very useful thing to say. If you don't understand why someone does something undesirable, your chances of anticipating what they are likely to try to do next is greatly diminished. I don't think many of us would want to put our lives in the hands of a doctor who said that kind of thing about an illness.
