Human Development and the Extended Mind: Review of _Becoming Human: The Ontogenesis, Metaphysics, and Expression of Human Emotionality_ by Jennifer Greenwood

Jennifer Greenwood's Becoming Human: The Ontogenesis, Metaphysics, and Expression of Human Emotionality is an innovative exploration of the empirical literature on human development and its implications for the extended mind debate. Greenwood argues that an examination of the emotional and linguistic development of children, especially the unique relationship between mothers and infants, supports transcranialism. I summarize her argument and then point to some of the strengths and weaknesses of her position.
