Participants on both sides of the contemporary debate between reductionism and anti-reductionism about testimony commonly describe testimonial knowledge as knowledge acquired at second hand. I argue that fully appreciating the distinctive sense in which testimonial knowledge is secondhand supports anti-reductionism over reductionism but also that it supports a particular kind of anti-reductionism very different from that typically offered in the literature. Testimonial knowledge is secondhand in the demanding sense of being justified by the authority of a speaker where this requires (...) that epistemic responsibility for meeting challenges to the audience's testimonial knowledge is shared between speaker and audience. The epistemic credentials of testimonial knowledge are in this sense importantly interpersonal. (shrink)

This chapter examines associationist models of cognitive development, focusing on the development of naming in young children — the process by which young children learn of construct the meanings of words and concepts. It presents two early-emerging insights that children possess about the nature of naming. These insights are: essentialism: certain words map onto nonobvious, underlying causal features, and genericity: certain expressions map onto generic kinds as opposed to particular instances. The chapter discusses empirical studies with preschool children to support (...) the contention that essentialism and genericity emerge early in development and that neither insight is directly taught. It also explores the question of whether these insights can be derived wholly from a direct reading of cues that are ‘out there’in the world, and concludes that they cannot. The implications of these findings for innateness are then considered. It is argued that both essentialism and genericity provide cues regarding plausible candidates for innate conceptual knowledge in children. (shrink)
