The metaphor of making a point always reminds me of a caveman sharpening a stick for use. This idea of sharp useage is very important to us. We seem to discard things that dont make points beause we think we cannot gain anything from the blunt metaphor. The fact remains, we live in a world of many more blunt obtuse ideas than sharp reasonable ones. My guess is that there are far more nonsensical sound groupings than there are actual words of which we are familar. The combination of nonsense and gibberish are infinite, while the rest are limited, but get repeated use.
My question is, do we continue to discard the dull blade of thought. Where is it discarded to, the subconscious? You know, you can see the New Jersey landfill from space? Its that big!
