Why "mysterious ways" don't matter.

[pocaracas]

And how did humanity reach such a declaration?
Did it pop into the mind of some enlightened person, one day?
Was there a vote on the matter?
how?

After all the atrocities, wars and injustices committed, not only in WWII but also before it, since the prehistoric period, Man can reach an agreement on our fundamental values. We are talking about a minimum everybody is inclined to defend. Only a small (and I mean REALLY small) minority of people will say torture, murder and slavery are morally correct. And I believe if we take away religion and public opinions influenced by religious thoughts, a bigger number of people would defend human rights and equality.

They didn't show up by magic, after historical and cultural occurrences some values were shown to be more important to support and preserve. Our values have an explanation, they are always a product of sociological, historical, religious (some), political, cultural and other kind of events who have shaped mankind's world view regarding morality.

I hope I helped explaining it

Yep... we like to think that's the culmination of our journey to unveil the ultimate guideline on human behavior.... is it done for good? Can it be amended and become even better?

It is possible that the holy books of old held in them such a culmination, albeit stuck at a time, now, too far away for us to properly identify with. But that's not stopping some people from following such guidelines and living their lives under them... They still work, under some constraints which can be found in most western countries. Why change?

If you believe there's a god and that there are rules bought forth by that god, then you will find that you are easily compelled to follow those rules.
If the rules come from a committee, meh... even if you agree with them.... rules are meant to be broken.

I say... let the deluded folk keep their delusions, they're less harmful under them.

The problem remains: people believe in the existence of some god. Fix this, and you'll have fixed the following of secular morality.
