Michael G: "". . . I think it's a matter that should be subject to empirical
test." 

I can't remember it exactly, but I think Engels has an interesting comment
in this regard. In reference to some claim as to the unity of the universe,
he argued that only the sum total of the sciences, which would never be
complete, could answer that question. So if we accept Michael's proposition,
we do indeed need to tolerate uncertainty. That is part of what I like in
Rosa Luxemburg's grim recognition that a plunge into ever deeper barbarism
was a real possibility. She cleared Marxist thought of the remnants of
19th-c "Progress" as structured into history.

Herb, Should a physicist have faith that the laws of physics are valid
throughout the universe? Unless that is simply a condition that any
candidate law must obey to be among "THE LAWS", I think it's a matter that
should be subject to empirical test.
