It's almost as if we need some kind of methodological approach which starts with an appropriation and examination of the concrete and surface level detail as the starting point.
Then moves behind those empirical/phenomenal like surface forms to examine and develop a hypothesis about the deeper roots & conditions which not only give rise to those surface like forms, but point to why those surface forms must appear in the way that they do
And then some kind of bundling together of that essence & appearance, in some kind of 'concept of reality' which in turn can then be validated to see if it's of any analytical worth by an ongoing testing of the results of that concept against the kind of concrete detail that gave us our starting point.
If only some kind of diagram encapsulated this process
Arguments about diagrams aside, I agree with what you say above about the approach, but I think you'll find the Kenny is arguing against such an approach. He thinks an understanding of what your're fighting against is not only not sufficient, not even not necessary, but actually detrimental to effectively fighting against it.
As per Spiney Norman's analogy Kenny (and Jazz) seems to be happy to go around trying to put out fires by trying to make them colder - an understanding of where the hotness of that fire comes from could only get in the way of putting out these fires in his mind.
Which is somewhat Ironic as both Kenny and Jazz display exactly the same approach to this, yet are on opposing sides of the debate talked about in the OP
