The Form of the Phi Kernel
This chapter considers the broader lessons that might be drawn from the current study of person. It draws out the core commonalities between the person and number features that have been proposed: that features are “operations” richer than first-order predicates held together by conjunction; that they are not subject to extrinsic constraints on order of composition or co-occurrence; and that there are semantic and morphological grounds for representing features of both kinds bivalently. The consequences of this study might ramify beyond linguistics by altering our understanding of and means of investigating the language of thought and the nature and evolution of mind. The author asserts, contrary to widespread opinion, minds do leave fossils, but these are to be sought, not by paleoanthropologists sifting through the archeological record, but by cognitive scientists, including linguists, via our theories of the structure of the mind itself.
