In addition to suggesting a systematic method to the discovery of the structure of commonsense knowledge, the method we propose seems to also provide an explanation for a number of phenomena in natural language, such as metaphor, intensionality, and the semantics of nominal compounds. Admittedly, our ultimate goal is quite ambitious, and it is no less than the systematic ?discovery? of a well-typed ontology of commonsense knowledge, and the subsequent formulation of the longawaited goal of a meaning algebra.
