Why do we like to quote philosophical pearls of wisdom? From Moses to Descartes, from the witty to the humorous, people love to associate themselves with the words of the wise and funny. I've never seen ditchdigger quips or any rice paddy wit & wisdom or garbageman humor make into forum poster verbiage.
It would be nice to see some originality from the membership but what prevents it? Lack of fame, smarts, or are we intimidated by our forum peers? Many people like to quote famous people for instance. Why? I rather see something paraphrased, at least you know the guy isn't googling all over the place in order to get it verbatim. A philosophical quote for any subect is like a notch in a gunslinger's holster for some of us. Showing off or trying to let the world know how smart you are? Doesn't do it for me.
I just find it odd that we resort to such measures in order to enhance a point we're trying to make. How can somebody else's quote make it into a forum signature...isn't it contradictory in a sense because a signature should be yours...no? Christ, I'm guilty of it myself.
