Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely).. . . I stress that my use of the term 'science' is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, 'science' (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)
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.
