Can i jump in here, because it makes sense to drop all the silly stuff(religion) and concentrate in what is real/factual/testable/re-testable/honest/reliable and the yet to be discovered wonders for the sake of our planet. Faith answers nothing.
Is that why we have had the likes of Pol Pot, Ceaușescu, Stalin and Mao during the 20th century?
To deal with the thread title itself, if we gave up our beliefs, how would we decide how to live? After all, we all have beliefs, be we atheists or theists.
"Is that why we have had the likes of Pol Pot, Ceaușescu, Stalin and Mao during the 20th century"?
What has the question just above got to do with this thread?

Because in terms of 'oughts', that is how we should behave to each other, science based on 'is' answers nothing
Assuming you are saying that Pol Pot ect, were using science based ideologies when they were doing their wicked deeds, well for one thing science is science as far as I know there's nothing more to science than that, it doesn't have an ideology.
Pol Pot etc didn't do their wicked deeds for the cause of science they just happened to be a type of wicked person that wanted to do wicked things because that was their nature and unfortunately people like this gain power from time to time, at he moment we've got yet another bunch of religious nutters out there in Syria and Iraq doing the wicked things this time.

You seem to have read my post as if it was from Hope and was a direct follow on from his earlier one - it isn't. You were suggesting we use only facts to decide what we ought to do. We can't - they don't help unless you make some earlier assumption. If religion answers nothing on this, it at least tries to, Science is unconcerned about it.
You are right in that in relation to science Pol Pot etc have no import. Indeed ideologies are merely in many ways secular faiths. My reading of Hope's post is that we can have such a thing as a secular faith, note this is different from a secular society though that difference is one that posters often try and blur. A secular society is essentially a liberal democratic construction that gives as much freedom to people that it can including religion. An ideology such as fascism can be secular in the sense of not being involved with the sacred but that's a different use of the term. It should also be noted that fascism could be part of a theology as well.
It's the quality I admire most in liberal democracy that it is a leap of faith across the ought is gap but it is the one that gives the biggest spread of allowance for being wrong.
Overall, call me thick if you like, I'm not sure exactly what your point was in that last post of yours.
I can't understand how or why Pol Pot Etc were mentioned, any more than say the price of fish in Halifax this morning.
My kind of secularism is a level playing field for all, the religious, or not, all get a vote and that's for me the beginning and end of any influence religion is due in every day life.
The nearest I get to fascism is buying the Daily Telegraph once a week Saturdays and that's only because it's so right wing it makes me laugh more than it annoys me.
A clarification of your post would be good, my brain isn't what it used to be.
