RE: [asa] Objective vs. Subjective

Hi Mike,

And with science, the ideal situation is to come up with new
measurements that might help resolves different interpretations of the data
(different meanings). That means the reality science shows us is contingent

upon the instruments we have to measure with and the ability of our minds to

interpret the measurements.

Yes, a good example I recently read (from a John Gribbin book) is the
separate claims made by Anaxagoras and Eratosthenes using the exact same
data. Anaxagoras measured the height of the Sun over Syene, Egypt to be
about 4,000 miles with a diameter of about 35 miles. Eratosthenes using the
same data determined that the Earth was 4,000 miles in radius and that the
Sun was very far away. Different meaning was found for the same data based
on different assumptions. Anaxagoras (pre Aristotle) assumed the Earth was
flat, but not Eratosthenes (post Aristotle and his spherical Earth view).

As an aside, consider the manner in which
Dawkins et al. like to argue that science can be used to determine God does
not exist. Even if we accepted their premises, how do they know the
instruments of today's science are sufficient for detecting God's existence?

He can argue all he likes, but if he tries to offer any objective evidence
that can be tested, it will be tested as false.

Actually, it's not that different in these regards, as subjective claims are

likewise open to scrutiny and testing. For example, if I claimed that
George Bush was the worst president in US history, this is a subjective
judgment call. It is open to scrutiny in that someone can ask me to explain

and justify my opinion. You could then "test" my belief in terms of its
accuracy when relying on facts/data and in terms of critical thinking and
intellectual honesty. Of course, this testing is not scientific because it
lacks the type of measurement that science uses (I think you are right in
pinpointing measurement as the divide between the objective and subjective -

there is no measurement for determining who was the worst and best
president). The testing is more subjective and thus cannot generate the
type of consensus that science can generate. Nevertheless, it is not only
better than nothing, but what we must rely on most of the time. Otherwise,
we are left with the notion that those who think Bush is the worst president

have an opinion that is equally valid to those who think he is the best
president.

Yes. Only if measurable parameters are agreed upon can "best" and "worst"
have cooperative meaning. But then others may disagree, and you will see
that either claim remains subjective. Further, even if he is the "worst" or
"best" today, he might prove to be otherwise as history unfolds.
