Look everywhere. There are miracles and curiosities to fascinate and intrigue for many lifetimes:the intricacies of nature and everything in the world and universe around us from the miniscule to the infinite; physical, chemical and biological functionality; consciousness, intelligence and the ability to learn; evolution, and the imperative for life; beauty and other abstract interpretations; language and other forms of communication; how we make our way here and develop social patterns of culture and meaningfulness;how we organise ourselves and others; moral imperatives; the practicalities of survival and all the embellishments we pile on top; thought, beliefs, logic, intuition, ideas; inventing, creating, information, knowledge; emotions, sensations, experience, behaviour.We are each unique individuals arising from a combination of genetic, inherited, and learned information, all of which can be extremely fallible.Things taught to us when we are young are quite deeply ingrained. Obviously some of it (like don’t stick your finger in a wall socket) is very useful,but some of it is only opinion – an amalgamation of views from people you just happen to have had contact with.A bit later on we have access to lots of other information via books, media, internet etc, but it is important to remember that most of this is still just opinion, and often biased.Even subjects such as history are presented according to the presenter’s or author’s viewpoint, and science is continually changing. Newspapers and TV tend to cover news in the way that is most useful to them (and their funders/advisors), Research is also subject to the decisions of funders and can be distorted by business interests. Pretty much anyone can say what they want on the internet, so our powers of discernment need to be used to a great degree there too.Not one of us can have a completely objective view as we cannot possibly have access to, and filter, all knowledge available, so we must accept that our views are bound to be subjective. Our understanding and responses are all very personal, and our views extremely varied. We tend to make each new thing fit in with the picture we have already started in our heads, but we often have to go back and adjust the picture if we want to be honest about our view of reality as we continually expand it. We are taking in vast amounts of information from others all the time, so need to ensure we are processing that to develop our own true reflection of who we are.

Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all 'faith' is grounded. In the words of Pope John Paul II: 'By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.' It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this. 'Faith' is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. 'Faith' is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence.But of course we never apply these lax standards of evidence to the claims made in the other fellow’s holy scriptures: when it comes to religions other than one’s own, religious people are as rational as everyone else. Only our own religion, whatever it may be, seems to merit some special dispensation from the general standards of evidence.And here, it seems to me, is the crux of the conflict between religion and science. Not the religious rejection of specific scientific theories (be it heliocentrism in the 17th century or evolutionary biology today); over time most religions do find some way to make peace with well-established science. Rather, the scientific worldview and the religious worldview come into conflict over a far more fundamental question: namely, what constitutes evidence.Science relies on publicly reproducible sense experience (that is, experiments and observations) combined with rational reflection on those empirical observations. Religious people acknowledge the validity of that method, but then claim to be in the possession of additional methods for obtaining reliable knowledge of factual matters — methods that go beyond the mere assessment of empirical evidence — such as intuition, revelation, or the reliance on sacred texts. But the trouble is this: What good reason do we have to believe that such methods work, in the sense of steering us systematically (even if not invariably) towards true beliefs rather than towards false ones? At least in the domains where we have been able to test these methods — astronomy, geology and history, for instance — they have not proven terribly reliable. Why should we expect them to work any better when we apply them to problems that are even more difficult, such as the fundamental nature of the universe?Last but not least, these non-empirical methods suffer from an insuperable logical problem: What should we do when different people’s intuitions or revelations conflict? How can we know which of the many purportedly sacred texts — whose assertions frequently contradict one another — are in fact sacred?
