Wells may see himself as Martin Luther nailing his reforms to the church door, but at the end of the book his call for political action sounds a lot like an attempt to suppress philosophical viewpoints that disagree with his own. He seems to think that science is not adequately spiritual and, as a result, less moral and caring than it should or could be. He is obsessed with the impact of evolutionary thought on man's place in the cosmos and how it spawns a godless, materialistic philosophy. He implies that evolutionary theory was created with that purpose. I was amazed at his efforts to impose political definitions on dead people.
Science is by definition engaged in natural explanations.
It cannot deal with the supernatural. Mixing the two has invariably resulted in bad science and corrupted religion. I think that this is especially true in education. If you want the latter, Wells gives instructions on how to put warning labels on books and get politicians to suppress what you do not like. If you think that evolutionary theory is a threat to civilization, you will enjoy this book in its entirety.
