Only as an abstract object, immanent in an actual use. What I think so far. — Srap Tasmaner

I was thinking (surprise). This is about how to ground force "in" the territory of a proposition understood as a set of equivalent truth conditions.
It seems generally comfortable, hereabouts, to conceive of propositions as that which is shared between the expressions _snow is white_ and _schnee ist weiß_. One way of fleshing out what is shared is that both expressions have the same truth conditions. Moreover, that both predicates "is white" and "ist weiß" have the same extensions and that "snow" and "schnee" can be used to denote precisely the same entities and type of entity.
What makes the first paragraph an account of what is shared between the expressions? The account finds that every
relevant facet of one expression would apply to the other, it does this by grasping a facet and comparing it to some idealised use case. When assaying the two expressions for their content, no one cares that plenty of humans exist now who believe snow is white but not that schnee ist weiß, in virtue of not speaking enough German - this is allegedly ephemeral, and so it is abstracted. I think it makes sense to call this discrepancy ephemeral because what one speaker
would do with the expression "snow is white" is (purportedly) exactly what they would do with the expression "schnee ist weiß".
But you can note that they share other things - when someone judges that snow is white, they would also judge that schnee ist weiß. When someone would reject that snow is white, they would also reject that schnee ist weiß.
I need to take a step back into the characterisation I gave of an extensional account.
A) An extensional analysis of rejection regarding a statement p( x ) must rely on the following claim: asserting the statement ¬p( x ) is equivalent to rejecting p( x ).
B) The equivalence in ( A ) requires that an asserter of p( x ) would commit themselves to all and only the same claims that a rejecter of ~p( x ) would.
Asserting and rejection in the above claim are in fact placeholders. A and B can be modified to refer to an arbitrary pair of relations to p(x), R and S. Each of them need a mapping that applies to p( x ) so that being in relation R to s(p( x )) is equivalent to being in relation S to r(p( x )). That criterion takes a predication, and says that being in relation R to it is equivalent to being in some relation S to some mapping of it.
Previously:
R=affirmation
r=identity
S=rejection
s=negation
A) An extensional analysis of R regarding a statement p( x ) must rely on the following claim: being in relation R to statement r(p( x )) is equivalent to being in relation S to s(p( x )).
B) The equivalence in ( A ) requires that being in relation R to s(p( x )) would commit someone to all and only the same claims that being in relation S to r(p( x )) would.
With that generalisation, ( B ) spells out the equivalence in terms of "commitment to the same claims" under some transformation of the judged statement. However, recall this paragraph in this post:
But you can note that they share other things - when someone judges that snow is white, they would also judge that schnee ist weiß. When someone would reject that snow is white, they would also reject that schnee ist weiß.
The normative machinery in ( B ), "commitment to the same claims", also applies to the judgements regarding snow being white and schnee being weiß - acceptance, affirmation, rejection, rebuking... . Ergo, the same machinery that sets up a criterion for extensional equivalence can also be used to set up a criterion of equivalence that assesses whether two expressions would commit you to the same judgements.
NB, the machinery which allowed us to assay the sentences and refine them into their propositional content with the extensional criterion is also allowing us to assay the sentences and refine them into a flavour of content which includes judgements. I think this heterogenous, but still orderly, collection are the forces we're speaking about. They're baked into the expression like the truth condition is alleged to be.
Whereas the illocutionary force concept is not baked into the commonalities between sentences whose factual content is equivalent. It operates on sentences with a given factual content. Forces seem aligned with the conditions that allow us to grasp an expression's content - content as affirmation, content as rejection. Illocutionary forces are means of operating on an expression's content, content as factual, rejection as practical.
Another aspect of this, which I've thought through far less, is the connection to "being" as Kimhi would have it. But I have an inkling of a way in. If propositional content has a privileged relationship with what is the case - that is, what
is - then force would be aligned with
what is using the same machinery as above. There is a duality in the illocutionary force concept - content as factual, act as practical - which the force concept avoids. Nowhere near comfortable enough with the thread's material to make that connection well yet though.
