[Phys-l] Postmodernism (Was: From another list)



It has some reasonable ideas.

There are certainly many truths in science in the sense that there are many
different ways of looking at events and at arriving at a conclusion
consonant with events.

We are certainly not engaged in searching for truth, but rather for ways of
describing what we observe so as to form a consistent coherent description
which can predict future experiments correctly. And remember that
observation is trained, so sometimes what one person observes is not what
another might observe.

Passion and conviction does count, but we do use rules to temper it. We do
use interpretation and sometimes it is only because we agree on it. A good
example is QM where at Copenhagen they voted on the interpretation. Bohm
switched sides and came up with a good counter interpretation and theory
which to my knowledge has never been refuted. So interpretation is what the
majority says it is. In other words we do work by concensus.

So some postmodernists have carried the pendulum all the way to the other
side. They have rejected absolute truth without acknowledging that there
are things that are "true" by a more reasonable standard. Scientific
"truth" is always provisional.

The one thing that almost certainly is "true" is the first line. People
often really do think that way. But the opposite conviction that all truth
is absolute is even more prevalent in our society. Witness the
anti-evolution tirades (they are not debates). Science, math, and history
are taught in an absolutist manner in most of our pre-college schools.
Students have discovered that many so called "facts" are not true, so many
of them swing to the other point of view.

So let us take the ying with the yang and consider that there is some
"truth" in the post-modernist tirade.

ABOUT FROM POSTMODERNISM -- FROM ANOTHER LIST.

Today's fashionable intellectualism goes like this:

There is not truth, or there are many truths.
There is no objectivity, or there are many objectivities called
subjectivities.
Reason which pretends to produce truth does not exist.
Scientists who pretend to use reason to produce truth are pretenders.
What is left is passion. Passionate people do not pretend.
It is being passionate that really counts because there is no truth, no
objecitivity, and no scientific method.
So those who are most passionate are most right.
Those who yell the loudest are the most passionate.
So those who yell and scream and are most obnoxious and insulting are
right, even if there is no right or wrong.
Those who yell and scream and are most passionate have the
deeeeeeeepest truths even if there is no truth.

That is pure nonsense, I think.
