This is a book worth reading. I have the “real” book, and it is a gem. You have to read it from the viewpoint that it was written in 1862, and so has 1862 values and context. But, that said, it has some very incredible points. One chapter in particular really amazed me: “Men of One Idea.” A quote:
There is no one idea in all God’s universe so great and so nutritious that it can furnish food for an immortal soul.
No matter how good the idea is (such as anti-slavery), you can enslave yourself to the idea if it’s the only one you have. This can happen to anyone in any religion (or science), and it has happened to some in Scientology.
It is, as I said, a book worth reading.
