What my father meant by this is always going to be ambiguous but I do
believe I know what he meant: He was saying that what is observed is "in the
eye of the beholder" and no two beholders, or observers, are going to see
things the same way. It refers to the idea of surrogacy; or substituting one
observer for another, because if you are using formalisms to represent these
observers, then the obvious difference between two human beings will not be
as apparent. He was musing on the fact that any observation that is recorded
is automatically contaminated by the specific observer who recorded it-- a
inescapable fact that has been the bane of science since the dawn of human
consciousness. The observation is then further contaminated by the person
interpreting it, and so on. He was also musing on the fact that formalisms
leave out crucial information that can completely change the seemingly
obvious result.
Many of the notes near that quote had to do with surrogacy. One discussed
using rats as surrogates for humans in medical experiments and so forth.
Surrogacy is a concept that is so widespread in human life that it becomes
an assumption. People tend to forget that there's a big "IF" at the
beginning of the whole exercise: "IF rats are close enough surrogates for
humans in this capacity, THEN drug A could be a carcinogen..." or whatever
the experiment is about. That can be very misleading with regard to analysis
of the data (where you then have the joy of further complications with
different people interpreting the data!).
With scientists observing some natural phenomenon and trying to understand
it, the "if" would be along the lines of "IF I am seeing this clearly enough
and in its entirety..."
Does that help at all?
