A galaxy of stars! Dirt is unique, unlike any other book I've read. (Bill Logan tends to write books like that -- his new one, Oak: The Frame of Civilization, is also unlike anything I've read, including Dirt.) The essay format works well. Logan's writing is cogent, witty, at times poignant; his imagination is fantastic. Rousing and satisfying my curiosity, he asks intriguing questions, and in seeking answers follows paths I would not have thought of but am glad to be led down by such a brilliant, quirky, earthy guide. Technicalities of soil science and geology are illuminated by personal experience and reflection on spirituality, childhood dreams Ilike digging to China), and encounters with masters of human achievement. This book may be ten years old but it's still exciting and provocative. I'm pleased to hear it is to be the subject of a documentary film; I hope that will lead to a reprint of this book, which is long overdue.
