This book has developed through a variety of classes taught at the University of Montana. I wish to thank my students for pressing me on various issues and "keeping me honest." I wish to especially thank the faculty and students of the Wilderness and Civilization Program of the School of Forestry. The University of Montana has provided continuous support for this project through grants and release time despite an ongoing fiscal crisis.
I wish to thank my colleague, Professor Richard Barrett, for suffering with me through this project despite his doubts and misgivings about the emphasis of the book. His critical review has helped me eliminate some of the confusion and error. He would want to be absolved, however, of any responsibility for the final product.
Becky Hanway suffered patiently through the preparations of the many drafts of this book and kept the production rolling. The staff of Typing/Word Processing Services at the university helped considerably with the final editing (when I would let them) and with the production of the final manuscript.
