It’s funny that when you discuss religion, mostly with those that pursue the belief with vigour; I always find the question of morality is thrown into the face of a ‘non believer’. The ‘non believer’ status often being attached to anyone outside of that particular religion and more rightfully (perhaps) to the innocent atheists, who is following their own belief set.
So when I saw this video featured on the Guardian but as part of a series (at the time of writing, yet to be fully published) I thought that I would spread the word. The arguments within are immensely succinct and highlight the certainty that God(s) is/are not needed for morals to exists, in fact religion is more likely in my opinion to warp a persons sense of morality.
More to this here to Epley article.
While we are on the subject of teachings and professional expert opinions (which surely religious leaders are seen as such) it may also interest you that studies (as in scientific, which will mystify the hardcore religious already – how is the internet btw?) show that when listening to a experts voices, we are so addicted to expert opinion, substituting our intellect to the illusion of certainty experts provide, the independent decision making part of the brain switches off. Despite the very real fact that experts are often and I do mean often are wrong. See video.
