On the Success of Scientific Theories

[Ben Davis]

I'm not quite getting it. Can you say again how you would rephrase the question?

You're right, I do need to rephrase. I also need to get rid of the word 'true':

P1) Our best scientific theories are successful. (note: a theory is successful when the predictions it makes are demonstrable).
P2) The best explanation for the demonstrability of science is that our best scientific theories are accurate.
C) Our best scientific theories are representative of reality.

That seems robust as it's logically consistent, experimentally justifiable and categorically complete (i.e. it includes scientific concepts such as mechanism, observability, repeatability/reproducability, measurement, data etc.)

We'd just need to agree upon definitions of 'demonstrable', 'accurate' & 'reality'. Now THAT's the can of worms
