I only think along the lines of 'Emotions are evil and wicked.', because they can cloud our logical judgement, as they do to everyone from time to time. Dale Carnegie wrote that we as humans are creatures of emotion, and it's true. While emotion is responsible for a whole hell of a lot of common mistakes humans make, it also makes us unique rather than just robots.

Is spite of all the bad they can to do to civility, I think we're better off with 'em in the long run.
