Belief and understanding work together in the human mind. Like many
such thing it needs to be managed, not worshipped.
I'd agree that there are matters where 'belief' really isn't a matter to be
subject to attempts to apply the scientific method. For me the concerns
just tend to be when either someone (religious or anti-) tries to shove
their views on others who have no interest. Or where, as in the examples
you give below, someone tries to dictate as a matter of their personal
interpretation something about how the observable universe works that
simply clashes with the observational evidence.
FWIW so far as I am concerned, beliefs like creationism are a problem best
left to Christians to resolve as it tends to have a negative impact on how
Christianity in a more general and thoughtful sense is perceived. My
impression is that many Christians don't accept creationism and find it an
embarassing or annoying distraction from what they actually believe.
So far as I can see, it is quite possible for someone to believe in a
deity, and accept a religion like 'Christianity' without having to also
accept 'add on' ideas that clash with observational reality
It is inherently anti-scientific to hold onto certain beliefs too
strongly. People are kind enough to show their true colors whenever I
say" "Evolution is just a theory". The usual believists who rail
against other's beliefs turn themselves upside down and angrily tell me
how it is an immutable fact.
Again, afraid I don't know who has said what to you on that.
However "Evolution is just a theory" isn't really adequate as a
description. The point is that Evolution as a scientific theory is
consistent with a load of experimental evidence and has not been refuted by
the scientific method. (i.e. by many experiments that gave opportunities to
give outcomes that would have conflcited with the idea.)
So "Evolution" isn't "just" a theory if "just" means "nothing else
involved".
It is also a number of detailed ideas, etc, which fit together as a
coherent explanation consistent with a large body of observatioinal
evidence and experimental results. IIUC The details of what is meant by
"Evolution" have themselves developed as further evidence and analysis has
been done over the years.
Gravity is far more fundamental than evolution and far more easily
observed, but even gravity is not an immutable fact. Gravity is
usually assigned to Newton who appears to have been a born-again
Christian. Einstein the non-obsevant Jew debunked it almost 100 years
ago. But it is still a useful theory.
Again that is rather missing the point due to an over-simplification that
fails to distinguish significant details. "Gravity" can mean either a
theoretical description and/or a proposed physical mechanism or cause
and/or the observation of the consistent patterns of behaviour we ascribe
to it.
So we now use General Relativity as the basis for theoretical study and
explanation of "Gravity" as it has wider scope and higher accuracy than
"Newton's Laws". Both 'theories' are extraordinarily good at explaining and
allowing us to predict/model a great deal in astonishing detail.
"Evolution" also does something similar in biology. But in each case the
details and approach change in response to the standard scientific method
being applied.
So "Evolution" occurs in that we can observe the details of living things
altering in response to environment, etc. And "Gravity" occurs in that we
can see thing fall, planets orbit, etc. In each case the current "theories"
explain a lot, but in science we always look for where we find a puzzle and
then use that to develop and improved 'theory'.
So the key point is that "Evolution" and "Gravity" are based on the
scientific method and being tested and altered in accord with critical
experiment and observation. But since I'm a physicist.engineer my knowledge
of Evolution is pretty limited, so you'd need to talk to an evolutionary
biologist to get a clearer view of that topic! :-)
We can make up all kinds of "theories". But the science part means that we
then use and develop those which stand up to tests against observable
reality. In practice 'Evolution', and both Newton and Einstein versions of
'Gravity' have done quite well on that score I think.
One of the more interesting things to watch is someone trying to
seriously teach something that they don't believe in at all. It is
lying, pure and simple.
No idea what or who you mean, I'm afraid.
One lesson is that we need to understand that the truth can be fluid.
Whose truth? Which truth?
Erm... that does lead to "What is Truth". Not sure you want to be in that
company! :-)
Personally I have no idea what "truth" means in such an unfocussed and
philosphical sense. Afraid I've tended to regard such philosophising as a
waste of time.
My interest tends to focus on what we can establish is consistent with
observable reality, and then use the scientific/rational methods to try and
see if we can form ideas that are useful in helping us understand, model,
or explain that. So far as I am concerned the closest science gets to
"truth" is to find at any time a set of explanations that fit what we can
observe as best as we can, and then seek to find newer ideas that have
wider scope or are more precise or are easier to use. As such all idea are
provisional, but may be very powerful as useful and accurate ways to deal
with reality. The scientific approach is to always look for flaws or
loopholes and when found, use them to try and build a better view that
explains these 'puzzles' as well as what we thought we already understood
well.
So in science "truth" is only "fluid" if your meaning of "truth" just means
"our current model of something" which science tends to expect will be
altered as new evidence crops up to be dealt with. It does not mean
"everyone can form their own view regardless of if it fits the evidence or
not". Hence "truth" isn't a term that in my experience is used much in
serious science. Theories may be "reliable" because they model a load of
observations and have survived many attempts to find flaws in them. That is
a practical and useful reason for choosing to use a theory.
I appreciate that in popular science TV programmes and magazines and
newpapers they talk about scientists "proving" things to be "true". But the
basis of science is actually quite different to that. The aim is to see if
you can show ideas are flawed by repeatedly testing them against observable
reality. When an idea keeps passing such tests it become regarded as a
reliable and useful "theory" rather than a weak or daft one that gets
dumped.
The problem here wiith "truth" is that it tends to lead to the muddle of
people who don't understand science saying things that boil down to
variations on "If we don't know everything then we know nothing" or "my
ideas are as good as yours". Such approaches may be fine in a pollitical
debate or a music circle deciding what to listen to next. But science isn't
like that, nor is engineering. There the ideas are tested against reality
in a way designed to search out and find any errors in the idea in terms of
not agreeing with observational reality.
Personally I'm happy to leave "truth" in an absolute sense to
mathematicians, philosophers, theologians, and lawyers. But I'm not sure I
always take them seriously. :-) Otherwise it is a concept I only use in
situation-limited contexts like digital logic or computer programs.
Slainte,
