So Fletcher Reede and Cal Lightman Walk Into a Bar

For the fun of it, plus also as a way of thinking about the importance of honesty by examining its opposite - dishonesty - consider the curious case of Fletcher Reede and Cal Lightman - two fictional characters used to explore the subject of lying. First, Fletcher Reede, Jim Carrey's character from the comedy 'Liar, Liar' - he's a compulsive lawyer - I mean liar. But I repeat myself. Second, Cal Lightman, Tim Roth's detective psychologist from the drama 'Lie to Me' which was cancelled before its time. What if it was impossible for us to lie? And what if we always told the truth in some form or fashion? Suppose with me what it would be like if we were incapable of saying out loud something we knew was untrue, or what it would be like if we always invariably gave it away through facial expressions and body language when we were trying to conceal the truth.
