The only difference seems to be the restriction "represents intellectual
progress" in the Thesis. So it looks as if the stronger thesis is that
formal methods are applicable where there is no intellectual progress.
So the weaker thesis is just that formal methods are applicable to every
philosophical problem where there is a possibility of intellectual
progress. Or am I missing something?

Apparently, I'm not missing something.

Counterexample 1: John Rawls, /Theories of Justice/
Counterexample 2: Peter Strawson, /Individuals/
Counterexample 3: Willard Van Orman Quine, /Word and Object
/Counterexample 4: Thomas Kuhn, /The Structure of Scientific Revolutions/
Counterexample 5: Saul Kripke, /Wittgenstein on Rules and Private Language/
I can't think of any formal systematization of the insights in these
books that would "fully subsume" them. That is absolutely not to say
that formal work can't be inspired by them, or important to the
assimilation and development of the insights contained in those books.
But it is asking far too much of formal methods to ask them to do all
With that said, I'd even add:
Counterexample 6: Saul Kripke, /Naming and Necessity/
And of course, it would have been even easier to list these:
Counterexample 7: David Hume, /A Treatise of Human Nature/
Counterexample 8: Immanuel Kant, /A Critique of Pure Reason/
Additional counterexamples are easy enough to generate. They don't even
have to be books.
