The Trouble With Memory Distinctions

People have an enormous variety of knowledge: for example, there is phonemic, prosodic, syntactic, lexical, semantic, and pragmatic knowledge; there is knowledge about sights, sounds, smells, tastes, feelings, motions, and emotions; there is causal, inferential, procedural, experiential, heuristic, and social knowledge, etc. Between these different forms of knowledge some make one set of distinctions, others make another set of distinctions, and there doesn't seem to be any good way to decide who is right.
