Some cases of implicit knowledge involve representations of
(implicitly) known propositions, but this is not the only important
type of implicit knowledge. Chomskian linguistics suggests another model
of how humans can know more than is accessible to consciousness. Innate
capacities to focus on a small range of possibilities, thereby ignoring
many others, need not be grounded by inner representations of any
possibilities ignored. This model may apply to many domains where human
cognition “fills a gap” between stimuli and judgment.
