How would you, for example, persuade someone else to believe this morality, and then, once you are satisfied that they have believed it, how would you encourage such a believer to preach this morality to others as if it were really universal? Can this be done without some level of dishonesty?
Be careful of over thinking this. As I said at the top, the vast majority of folks are not philosophers. We aren't designing a system for philosophers, who are of course, already perfect as they are.
I don't feel we need dishonesty. As example, I sincerely believe every human being is born "with certain inalienable rights". I could sell that without any inner conflict.
Yes. I'm trying to get at how you arrive at said 'shared conviction'.
Quite a bit of shared conviction already exists. What I'm suggesting is that fancy talk thinker like us not undermine that shared conviction by trying to replace it with moral relativism.
That sounds like the world as it has always been. Not at all perfect, but the worst of it seems to be the endless bloody conflicts between the followers of the preachers of different and conflicting 'Universal Truths.'
There's a conviction of "rightness" that while not universal, is widely shared. Religious violence is bad.
I agree that violence arising from competing truths are a problem, but we're not going to solve that by discarding all truths.
Neither have I. Have looked at the synopsis though. Looks like it might be saying the same thing you are saying. I'd be interested to read what you think if you get a chance to read it.
Please remind me if I forget.
So who produces the sermon in the first place? Whose version of morality shall we adopt as the 'Universal' one? Who gets to pick, vote, or design from scratch, the successful code?
I do. Next question?
Seriously, I'm less concerned with inventing a new moral system than I am in rejecting relativism. Although there's quite a bit of quarreling over the details, there's actually pretty wide agreement on some important fundamentals. Let's not toss that out in our passion to be intellectually clever.
Would you accept that 'pretending to believe' would suit your purpose of peace and order etc., as long as everybody pretended to believe the same thing?
How about this? We might identify those things that most people sincerely believe to be RIGHT! And then strengthen that agreement, rather than undermine it.
This still leaves the vexatious question of what to do about the actual world, in which lots of different people actually do believe lots of different things.
Recent events in Egypt offer an example.
There's been lots of conflict in the world for the last 500 years between democracy and dictatorships. We might conclude there's a great division.
What events in Egypt reveal is that there really isn't such a big division. We want political freedom for ourselves, and millions of Egyptians do too. Those who disagree are a tiny, if determined, minority.
