“…[an] imaginative, engaging book… directed primarily to the layperson and the beginning student. There is an abundance of examples.  But this (almost) excess of application turns out to be one of the book’s strengths: through it emerges an author/teacher whose vibrant determination compels the reader/student to want to understand. Another, related strength is likewise rare; the book attends closely to ‘ordinary’ life without compromise of analytical depth and rigor.”
