If there is anyone out there who read the comic book 'Beezer' as a kid then you will be familiar with 'The Knumbskulls'. A strip about a guy with little dudes living in him that control what he does. This short uses the same device to make an important, kind of subtle, point to us.
Some guy, starting out as a baby, sometimes follows his emotions and at other times sense. Just like everyone else. He sees a woman he likes on the street and follows his emotions. It ends up a slap in the face, but her common sense reacted, not her emotions, which said 'yes'.
The point of this is that Hitler used emotions to keep the Nazi's brainwashed. None of them used common sense to figure out that he was a lunatic.
But perhaps today we should still use our common sense to not believe rubbish published in tabloids or biased news stations. The logic applies to many things, not just Hitler's Nazi regime.
