Book excerpt: Minds are rhetorical. From the moment we are born others are shaping our capacity for mental agency. As a meditation on the nature of human thought and action, this book starts with the proposition that human thinking is inherently and irreducibly social, and that the long rhetorical tradition in the West has been a neglected source for thinking about cognition. Each chapter reflects on a different dimension of human thought based on the fundamental proposition that our rhetoric thinks and acts with and through others.
