"Yet we still don’t seem to have made any breakthroughs on the most perplexing of human problems, especially that of humans living together in robust peace. Secular humanism, however, continues to stake its hopes on science and rational thinking as the key to solve the tough problems."

Given what you say it is somewhat ironic therefore that many of humanities problems with violence are due to religious beliefs. The very book that christians are so devoted reeks of genocidal madness at the direction of god. The morality of the OT god is consistent with that of a bronze age jealous tribal maniac. I believe that only when humanity puts aside these silly notions of invisible beings who are supposedly directing his followers to kill or dispise everyone that doesn't follow the same particular flavour of belief, will mankind finally realize that we are one family and that our survival is dependent on each other.

This earth and all its life was not put here for our benefit as the bible says. We are merely a bit player and rational thought is needed. Time to put aside these juvenile beliefs. Time to grow up. All children eventually stop believing in Santa Claus. There is no need that he be replaced by another imaginary person.
