Query: The book isn't quite so clear.

I am a student using this book. I find John Hospers book to be one-sided and narrow minded. It is not a useful source to teach or learn with. I have yet to learn anything from this book. I took this course to further my knowledge in problems of ethics and reasonable solutions to these problems, but haven't gained anything from his writings. It's sad because we have such an intelligent group of students and a knowledgable professor and I feel as though our talents are wasted.
