I read this book as part of a class assignment. Also, I think it is important to mention that my educational background is in psychology. I believe both of these characteristics that I think affect my impression of this book.
The idea that we operate in paradigms that shape how we interpret the world around us helped explain a lot to me. These points really resonated with me. But I do feel like this book is a little dated in some aspects. In particular, he keeps referring to the environmental movement as the "new" paradigm. When he wrote/published this book, environmentalis was the new movement, but I don't feel like it is today.
The date of the book also has an effect on some of the examples that he uses to explain his concepts. He drops in names/events without a lot of backstory. I feel that someone who was a working adult at the time this book was written/published would probably get a lot of the references, but I was still in high school. So I don't get them all.
But I did really like the chapter where he went through a few different examples of paradigm shifts in more detail. That chapter answered a lot of the lingering questions that I had from the previous chapters.
