““Thomas Edison said in all seriousness: "There is no expedient to which a man will not resort to avoid the labour of thinking"-if we bother with facts at all, we hunt like bird dogs after the facts that bolster up what we already think-and ignore all the others! We want only the facts that justify our acts-the facts that fit in conveniently with our wishful thinking and justify our preconceived prejudices! As Andre Maurois put it: "Everything that is in agreement with our personal desires seems true. Everything that is not puts us into a rage." Is it any wonder, then, that we find it so hard to get at the answers to our problems? Wouldn't we have the same trouble trying to solve a second-grade arithmetic problem, if we went ahead on the assumption that two plus two equals five? Yet there are a lot of people in this world who make life a hell for themselves and others by insisting that two plus two equals five-or maybe five hundred!””
