|Robert, I'm not sure what angst-ridden people you're talking about.|
The way I see it, lying leads to these epistemological consequences. If you try to maintain the lie, and keep the truth hidden, you either have to work at it very hard, or you have to believe the lie. The article points out the same is true for beliefs in the arbitrary. Those who think they can keep their faith separate from their reason are either doing all the hard work to keep them entirely separate, which is an error-prone project at best, or they're mixing them all up.
Of course there are also people who just don't bother keeping the truth hidden. That sounds like the people you're talking about. Those that lie and get caught all the time, but just don't care. They don't feel guilty or stressed because they aren't afraid of consequences.
I've met all three. I've met people who struggled to maintain their lies, stressing out completely and wasting a huge amount of time and energy. I've met people who simply believed their own lives. And I've met people who just lied all the time without worry or care. None of these people could be described as happy.
I can't be sure, but you seem to think that a liar who doesn't feel guilt is somehow happy. Your post 35 describes what you mean by happy, and it's one which I disagree. They might find some fleeting pleasure in their actions, but the actual consequences to their lives are quite negative. I've known people who lie and cheat and steal, and they certainly can't be described as happy in the wider sense. A lack of guilt does not make someone happy.
Of course, there are always conditions where justice is thoroughly perverted and these kind of people get away with far more without incurring the negative costs. I still wouldn't view them as happy, but certainly they have a better opportunity to live an irrational life without paying for it.
