When you do, some things are immediately phenomena in these fields. When you do, some things are immediately obvious. For example, it's immediately obvious that language involves a obvious. For example, it's immediately obvious that language involves a discrete infinity of constructions, that grammar involves iterative rules of discrete infinity of constructions, that grammar involves iterative rules of several types.
