[email protected] Abstract: A theory of conceptual development must specify the innate representational primitives, must characterize the ways in which the initial state differs from the adult state, and must characterize the processes through which one is transformed into the other. The Origin of Concepts (henceforth TOOC) defends three theses. With respect to the initial state, the innate stock of primitives is not limited to sensory, perceptual, or sensorimotor representations; rather, there are also innate conceptual representations. With respect to developmental change, conceptual development consists of episodes of qualitative change, resulting in systems of representation that are more powerful than, and sometimes incommensurable with, those from which they are built. With respect to a learning mechanism that achieves conceptual discontinuity, I offer Quinian bootstrapping. TOOC concludes with a discussion of how an understanding of conceptual development constrains a theory of concepts. Keywords: bootstrapping; concept; core cognition; developmental discontinuity; innate primitive 1. Introduction determines the content of any given mental symbol (i.e., what determines which concept it is, what determines The human conceptual repertoire is a unique phenom- the symbol’s meaning). (In the context of theories of enon, posing a formidable challenge to the disciplines of mental or linguistic symbols, I take “content” to be the cognitive sciences. How are we to account for the roughly synonymous with “meaning.”) The theory must human capacity to create concepts such as electron, also specify how it is that concepts may function in cancer, infinity, galaxy, and wisdom? thought, by virtue of what they combine to form prop- A theory of conceptual development must have three ositions and beliefs, and how they function in inferential components.
