specs (Nelson Uorrea). i0. We are not skeptical of theory, Just of existing theories. At first blush, it seems unnecessary to conjure up any justification for titis claim. Almost by definition, the proper business of a grammar should be grammaticality. However, it has been notoriously difficult to draw a line between "gram. maticai" sequences and "ungnmunalicai" sequences, for any natural human language. It may even be provably impossi- ble to define precisely rhe notion of grammaticality for any language. Nalural language deals with vague predicatus, and might itself be called a vague predicator. This being tree, it still seems worthwhile to ~ at parsing ALL of the gr,'unmalical strings of a language, but parsing ONLY the grammatical strings becomes a dubious enteq~rise at best. Arguments...
