Taking their inspiration from the ancient skill of blacksmithing, the authors of this book take a fresh look at the mental processes involved in the accomplishment of goals. They analyze the way people apply what they know in order to reach a particular end, whether it is material or conceptual, routine or novel. The authors, anthropologists Janet and Charles Keller, provide an account of human accomplishment based on a detailed study of contemporary blacksmiths. The cognitive realm of blacksmithing is of particular interest because it relies on visual imagery and physical virtuosity rather than verbal logic, the conventional yardstick of cognition.
