I think it would look exactly like it does, since there is no god.
But I suppose you mean how would people act in society without fear of punishment or hope of reward? I think we would be more advanced, at least in a few areas. Scientifically speaking, things would be more advanced. Religion keeps people from experimenting and trying new things. Stem cell research? We would have created cures for tons more things by now! There would be no more children dying because parents refused medical treatment in favor of prayers.
If there were still wars, they would be created by a need for power, not because of religion. Women and men would be equal in all countries, because there would be no scriptures stating otherwise. Morals and ethics would be made using common sense! Perhaps there would be less local crime, but not sure I would go that far.
Yes. Two answers for this question:
1. A world without the supernatural God ( to which I agree with Moria )
2. A world without the idea of God
It's an interesting question and one at which we can only conjecture an answer. I believe it would look remarkably like what we have now. There would still be social inequality, there would still be war. We would have just one less reason for those things but that isn't to say that they would disappear completely.
This is difficult to answer because as religion/god belief withers away, there’s no similar broad discussion of what to replace it with. And why should it be replaced with something? Well, in many ways, religion fills a sort of empty void in people’s lives. It provides a social cohesion in many communities, while at the same time blinding people of so many other factors about life. So yeah, as religion withers away, I think we could possibly see a resurgence of enlightenment where people free themselves from social biases and political strife that has been largely influenced by various religions. Where education would help people to start thinking more critically, using scientific methodology. Where we could be more open and accepting about our sexual desires and different sexual orientations. Where we build a world that is not divided by race and nationalism. But again, I think it’s hard to tell, because we’re still so far way from a god-less society or world.
fills a sort of empty void in people’s lives
Off the top of my head:
- the fear of death
- the infinite amount of needs and wants
- social recognition
- magic, and the power to move mountains with faith
- hell & heaven
Unfortunately, I think there is also a good chance that it would be an easy "search & replace" of religion with an alternative dogma such as blind patriotism. Or some political, economic, or other philosophical viewpoint (communism, capitalism, libertarianism, green, etc).
The world would look a LOT different. Remember that the Dark Ages held us back significantly. There was a period of around 800 years where science and progress were considered heresy. During that time, a lot of the scientific progress that had been made by many human cultures was lost. The steam engine comes to mind, which was invented in the 1st century by a Greek scientist living in Egypt. We didn't rediscover that for almost 2,000 years! There were also things like mechanical doors, Da Vinci's famous designs for an airplane, etc.
Without religion, I believe we would've had the Internet, cars, cell phones, etc. sometime around the year 1200. There's no way to imagine just where we'd be by now, if not for religion holding us back and even dragging us backwards!
