However, I think I would like some clarification on this:
Every society and civilization collapses for the same reason: the people in that society start to place self-interest and partisan interest over the good of the society as a whole.
At first, this sounds like collectivism, but I am not sure after I read the rest:
Political contests become angrier and more contested, and when one group wins, it fells justified in using its new-found power to take revenge on the other.
I'm not so sure that's what we have now. If the Republicans wanted to "take revenge" on the Democrats, then we would not have seen the things passed that have been. Instead, we would have seen investigations into illegal pardons, stolen technology, etc.
I wonder, do you mean "for the good of society" in that we pull our troops out from around the world, forget about those countries, and restore freedom in our country?
Okay what is illogical about Leonard Peikoff's criticism of the pacifist wing of the LP?
