This book was given to my by someone who knew I was a fly fisherman. Although I found the observations of wild summer steelhead interesting, much of the rest of it, focusing on the surrounding flora and fauna, not so much. The author does a good job recording what he observes, and much of it I've experienced myself. Only not to that degree.
I view nature as a creation of God and this author views Mother Nature as god. Nowhere in the narrative, while he described the beauty, the intricacies, the complexities and the order, did he once mention God.
And without God there would be no order, as nature doesn't naturally progress, but instead regresses.
He does a great job recording what he sees, but as to the why of what he observes, I didn't agree with many of his theories.
Because of his biased worldview, and trust me I also have a worldview, he fails to recognize man's superiority over animals. He tries to equate the two and even insinuates that animals are superior.
If fish for example, have superior analytical skills and can decide what they want to do, then why do all of them do exactly the same thing, year after year? Why no rebels saying, "Well, I'm not going to go up that river to spawn, but instead I'm going to hang out here in the ocean.
The one thing Mr Spencer does well, which corresponds to a scripture verse, "Be still and know that I am God." That is the conclusion I would come to if I could slow myself down enough. Mr Spencer never recognizes God's hand in any of it.
He also takes it upon himself to play God by suggesting man should not be allowed near these beautiful creatures, with only him left to observe and enjoy.
