Atheists are able to adhere to the view and practice of “do unto others.” They just don’t have any (known) recourse for their mistakes, which can make them throw up their hands in despair. Many times they find their values in the discoveries of Science — and science eventually confirms what the Bible said all along, since the Bible is the Truth, for instance in regard to the permanent effects of oxytocin (released during sex) on the brain: it has now been confirmed scientifically through studies of the brain that we only truly can bond with one individual, after that, the adhesive or velcro of intimacy starts to wear off. I am seeing a psychologist who is an atheist, and it works for me. He is more honest and empathetic than a lot of Christians. We do however deal only in the “here and now”. It is more a life coaching kind of thing than “tell me about your mother,” which is why it works for me, I think. Also, I did let him know up front that I would like to get through the course of therapy with my Faith intact, so he tip toes around that topic and my values with respect and gives it a lot of space.
