Everything (except subatomic particles) in our tiny solar system moves
so slowly that classical mechanics is extremely accurate.

What does that have to do with celestial mechanics or sustainable
agriculture? Those phenomena are too small to be very relevant.

I see, when you say "other levels" you really mean what people think
about, rather than the system itself. So, if I were to write a poem
about the solar system, that would be a different level than Galileo was
addressing. I can go along with that. I thought you meant something
more profound by "level."

It was up to Newton to complete the picture, for practical purposes.

That's nice, but doing it doesn't affect the operation of the solar
system, so far as anybody can tell.

You are changing vocabulary on me. By using Einsteinian jargon (even
though relativistic conditions clearly do not apply), you try to infuse
respectability into your ambiguous concept of "level". I reject the
notion that reality is parochialized into competing "frames" or
"levels". Reality is one (even if we only know a little). Further, I
reject the proposition that domains of knowledge exist which are
incommensurable.

In a practical sense this means that if LionKuntz sells me a
"biodynamic" formulation that has been blessed by her shaman, I can put
in replicated trials and find out if it works using an F test. Finding
out why it works could be a lot harder, I admit!

See Misha, I think you (and several others on the list) are ontological
relativists. You want to reify your mental constructs rather than
immerse yourself in the simple reality of nature.

I wish that the environmental movement could get past the romantic
relativism (having roots in mind/nature dualism) that sees traditional
agricultural science as unnatural. I don't believe that the competing
viewpoints are incommensurable. I think I understand where you are
coming from.

The academic left has seized on this whole incommensurability
idea(different modes of knowledge) as a tool to drive a wedge between
the scientific community, and farmers trying to be environmentally
responsible. I think this is very unfortunate.

I think you are driving that wedge right now!

I agree!!

I thought I killed the snake! Folks, don't be fooled by the new age
"physicists." Scientific knowledge IS experiential knowledge. That
frame-of-reference stuff is just smoke and mirrors hiding a political
agenda. The political agenda is a worthy debate, but let's try not to
entangle it with the simpler reality of agricultural systems.
