If a chimpanzee could talk and other reflections on language acquisition

"In this book, a philosopher combines famous cases with a lifetime of study to examine the threshold of language--that point "between speech and not quite speech." He provides fascinating accounts of the deaf and blind Helen Keller, of chimpanzees like Washoe, and of feral children such as Victor, the "wild child of Aveyron," putting a new spin on their stories. When does it start, he asks, that miracle most of us take for granted? Where does it come from, that uniquely human power to transform perception and action into thought and the singular activity we call speech?"--Back cover.
