I've some sympathy for the idea that the limit of one's language is the limit of 'one's world', if by that we mean worldview or belief system. However,
Banno proudly conflates word and world, by not drawing and maintaining the actual distinction between belief statements that are about language use and belief statements that are about mice and trees. Part of that comes as a result of overstating the strength of the case that the belief that approach makes. Another part comes from the idea that truth is unanalyzable. Another from his preference for a redundancy approach. Another from a conflation between truth as coherence and truth as correspondence.
Truth - as correspondence - is presupposed in all belief statements. That's how/why "is true" becomes a redundant use of language. However, "is true" is not equivalent to truth. "Is true" marks belief(assuming sincerity), and belief while it is necessary, is also insufficient for truth. <-----
Banno would object to the necessary part, but the objection is based upon a misunderstanding. Belief is necessary for correspondence between belief and fact(what's happened) because when and where there has never been meaningful belief, there could never have been a meaningful correspondence between belief and what's happened. It's insufficient because some belief is false.
Human thought, human belief, meaning, and truth are all things that exist in their entirety prior to our talking about them. Those sorts of things are peculiar in that it requires language to become aware of them and their role in our lives, and we can most certainly get them wrong.
Since all belief is meaningful, being meaningful requires meaning, and language-less creatures can form, have, and/or hold belief, it only follows that meaning is prior to language.
The question then is what does such meaningful belief consist of? Hence, this debate.
Not propositions.
