I don't understand what it is that you want to say, even if we were to accept all of your premises. That other than math and physics we actually know nothing? That knowledge (even if partial) is meaningless unless it is as rigorous as the one we can attain in physics, the simplest of sciences? Obviously we can be less confident of results in the complex/intractable/inexact sciences than we can in the simple/tractable/exact ones. You want to call only the latter group "science" and the former something else? Fine. Does that mean we should completely ignore all results in disciplines which aren't science?
