Jack - Our last conversation helped me to add the next step to my attempt to elucidate the form of living standards of judgment. . . . The progression currently runs as follows (using my best Tractatus-esque mode of linear reasoning): * We cannot say what a standard of judgment is. * We cannot describe standards of judgment using propositional forms of language and logic. * Within a dialogical and inclusional conversation with another, we know when we have agreed a standard of judgment and applied it to the matter on hand: it enables each of us to say "I now know that you understand what I mean". * We co-generate living standards of judgment as we enquire into our forms of life and share them within educational action enquiries. * Collaborators within an action enquiry agree standards of judgment in order to progrees their enquiry. * There are certain positive personal attributes and certain appropriate modes of enquiry that dispose people to being able to collaborate within an action enquiry and to co-generate the standards of judgment required to confirm that current aspect of the enquiry as being educational. * It is possible to describe/depict/represent those attributes and modes of enquiry that encourage the co-generation of standards of judgment. * What we cannot speak about, we must pass over in silence (but that, dear Ludwig, does not mean we can't try to SHOW each other what we mean by using webcams, Facebook and other such e-delights not available to you in 1917). - Pete
