I think you and Moose are just talking about the same philosophy, but with different words.
Let's take Newton's laws as an example.
Newton's laws are 'right', and Moose would say that Quantum explanations are 'more right'. All this time though, Moose is still not pursuing any 'absolute truth goal'.
You're saying that Newton's laws are 'not very wrong' and then saying that Quantum explanations are 'less wrong still'. Again, you're focusing on not pursuing any 'absolute truth goal'.
In this context, we can see that 'more right' and 'less wrong' can describe the exact same circumstance.
I agree with Nosy though... that even if the philosophy is the same, it is less confusing to only talk in 'less wrongs' for outsiders to understand what's going on. As soon as the talk of 'more right' comes up, an outsider can easily mistake that for some sort of pusuit for an 'absolute truth goal'. And that is worth a bit of re-wording to try and avoid.
Meh. Semantics.
