It seems that religion can inspire people to do more than then they thought possible. That is, if someone believes they have the power of God in them, (for example) they will have greater confidence, drive, perseverance to do greater things. Now, I believe this ability to do great things comes from the increased confidence, drive, etc and not from any super natural being. But the religion influences these attitudes and behaviors.

As to whether this is good or bad for society, that is debatable. A person can either be inspired to do great good or wickedly evil things, all in the name of religion. If a society believes in a religion and that religion inspires in people goodness, hard work, honesty, etc. does that make a society more developed. I think it makes a society stronger in may ways. However, this may be your "religion is used to control a society" point of view, and I agree with you. The society is probably less developed in that sense.

Personally I believe that we should seek the truth wherever it may lead us. I think we face illusions every day. Historically, when we can not explain a phenomenon, we are tempted to create some imaginary god, or supernatural force to explain it. We cannot explain conscousness so we say that we must have a mind. We cannot imagine non-existance so we believe there must be a soul that survives death. Most may be illusions, however.

Good topic. I haven't checked out your link to physicsforums yet, but will do so. It will be interesting to see others opinions.
