... I love it. It made me think. Not too many novels do that.
Sure, The Probability Broach is a little heavy handed at times and the characters could have stepped out of a Heinlein novel. And I don't think that anarchy is the perfect solution for any civilization.
But within those boundaries, Smith has crafted a world similar to ours but with a society whose viewpoint is at right angles to ours (well, maybe 45 degrees, since I tend to agree with Smith on a lot of his points about personal rights and personal liberties.)
We all get a mindset from our parents, our friends, our religion, and, of course, our government. In the extreme that has led to atrocities like the Nazi party and the current terrorist threats. But what if these people had been brought up to learn to 1) think 2) respect others by staying out of their lives 3) depend on themselves to support and defend themselves 4) think that what they earn is theirs 5) let competition flourish?
The world might be just a wee bit different.
Not everyone will like this book. I happen to. It made me examine some of my convictions - and where I got them from. They didn't change, but I'm sure that Smith would argue that that's my right.
So, buy the book. Read it. Don't worry too much about my personal bete noire of limited characterization. This is a thinking Science Fiction book. It may make you angry or it may make you giggle with glee, but it WILL make you think.
By that criterion, this is a very good book. And don't forget that some books discussing or praising a different political or social outlook have turned out to be classics. Ever read Utopia, Gulliver's Travels, or Atlas Shrugged? If not, you should.
So, read The Probability Broach with an open mind. Agree with its philosophy or don't agree with it.
