I think it's way too early to suggest that a "Humanist" approach to society would do societies or cultures any good. Mankind appeared around 200,000 years ago, and radio waves were discovered around 1870 (maybe order a plate of E = mc2). There are many examples today of scientists and academia making the "unseen" seen. I think we are far from understanding ourselves, our planet, or our universe. There are simply too many things as yet "unseen" and "unknown" about how things work. So, I believe a blend of science, faith, and the humanities as a global awareness facing forward to the future is our best endeavor. What don't know what we don't know until we know it - type thing. We humans do feel spiritual at times, and connected to something larger than ourselves. That doesn't mean (s)he/it is an almighty God anymore than it means it was an energy process and chemicals.
I say combine our sense of awe, reverence, love, beauty, desire and curiosity to abound into the boundless - let's find out what we don't know and who or what "did it!"
