It is one thing to overthrow the tyranny of ideology, and another thing altogether to forsake all models of how the world works. The radical extreme of deconstructionism is that all ideas are false, or at best, meaningless. The further implication seems to be that all ideas are therefore useless . This is where I draw the line. I am actually quite comfortable with the proposition that no idea is absolutely TRUE, at least as mediated by language.
Language is, in a sense, a system for building models, metaphors of what is going on.
It is very important to realize that all we have to communicate with are models of reality. Some metaphors are incredibly powerful. They can lead us past manifold distractions into rich and rewarding experiences. Others can lead us nowhere, except to waste great amounts of time and energy. What is important here is to balance the usefulness of a presiding model with a degree of flexibility.
