How critical it is! Why is it even called? What does its location in an utterance (before an article and name of thing) have to do with its function (identifying the relationship between a thing and the universe)? Does the reference to position detract from the importance of the relationship between place and function? Or does it serve to ignore function ab initio. Form vs. function suggests an antagonistic stance. And form is clearly preferred by those who depend on superficial optics to define reality. Is it a given that those who fixate on what a thing is have little or no interest in what it does?
Why are appearances deceptive? They are not. Our perception varies as a result of differences in illumination. How do we perceive motion? At the speed of light? Which is too fast for the brain to register?
