What other kind of valid interpretation of reality do you accept beyond scientific method and atheism? ... You seems to use science and atheism as the only two kinds of valid and universal knowledge. - John_Mann
Hi John thank you for the question. Let me take the second part first.
Atheism isn't a basis for knowledge in that sense. It is simply a lack of belief in the claims of theism. If somebody is unconvinced that there is a supernatural being who is immanent and involved in the affairs of humans - who cares about our actions and judges us after our physical deaths - then we are atheists.
But that tells us nothing else about the atheist or about reality. I know of atheists who believe in fate or in astrology or homeopathy and all other sorts of irrational woo.
My appeal is for a rational, evidence-based approach; a commitment to discover what is objectively true about our world. The big change in my intellectual life was not when I left the Watchtower in '85 but when I abandoned faith as a valid basis of knowledge in '94. Being rational means that our beliefs should be in proportion to the available evidence.
Claims about supernatural worlds, gods, angels, souls and spirits are irrelevant in the pursuit of knowledge and in the moral debates of our time.
Science is the best method we have for uncovering facts about reality. It's how we try to get past our biases and superstitions and investigate the world objectively. Of course is has its limitations. Science cannot tell me whether I ought to prefer Martin Elliot's "Tennis Girl" poster (£2.99) or Tracey Emin's "Unmade Bed" (£2.2m) However there is a lot it can tell us about human nature that might explain my personal preference.
Science is based on an assumption of methodological naturalism. That doesn't mean that a scientist has to believe there is no supernatural world but that he must leave the supernatural outside the lab. If he is investigating the efficacy of a new cancer drug he can't factor in the effects of intercessory prayer. When he is investigating the possible benefits of human stem-cell research he cannot limit his pursuit of progress in case a frozen blastula might be imbued with an immortal soul.
Similarly when wrestling any moral dilemma the question of what decision will make god happy is inadmissible.
