Old Samuel seems to think that if we all just knew that we don't have free will, things would be so much better. We'd all live in a state of reasoned and logical harmony, sharing kindness, charity and forgiveness as we realize that our enemies and irritants cannot help themselves.
Why Sammy thinks we'd end up with Christian ethics rather than Caligulan ethics is never fully explored. That's probably because Sam doesn't want to to be thrown to the lions in the arena and so he pretends that Christian ethics would somehow win out in a Darwinian sense. LOL! That's not the only area in which Sam has a rich fantasy life. When you start thinking about the world he proposes, it gets even better.
Imagine raising your children to believe that they do not have free will. Imagine the parents of your kids' classmates doing the same. Discipline would last, oh, I don't know, about 15 minutes or so. A pack of 8-year-old boys who have been convinced that they do not have free will would become completely unmanageable by anything short of fire hoses and dogs.
And dogs they would be, too. Without any sense of free will, you'd have to fall back on pure stimulus-response training to keep them in line while they constantly tried to push things to the limits. After all, why not?
And what happens when they realize that you don't really love them? You don't, you know. Love is meaningless when there is no free will behind it. "I love you" would engender the reply, "So what? You had to. You have no free will!"
Finally, imagine how awesome classrooms would be. Kind of like an ongoing MMA brawl.
Hmm. Some classrooms are may already be there.
