John Muir was a genius of natural understanding, and this book doesn't really explain why. His life is beyond explanation. But he sure can tell a tale! It's a fascinating look at new immigrants to the U.S. in the 1800's. John Muir is such a man apart that every page is mindblowing. He has thoughts and experiences that will appeal to nearly every reader. His schooling was remarkable, his work ethic unrelenting, his desire to learn insatiable, his boldness irrefutable. He relates his thought processes in a way that opens the window to his soul, and you learn to know a man who you really want to know. His instincts, thoughts, motives, and wonderings guide the reader's mind to productive and beneficial thoughts. I loved this book!
