I think you have it backwards. If I normally pout when I'm upset, I
can ostensively pout in order to communicate to you (I may or may
not be dissembling) that I'm upset. The communication works because
I know you aware of the causal connection "if upset then pout --
pouting is a symptom of being upset". I maintain that "ui" et al,
along with "ouch" and "O fuck"  are exactly like this.

So which position is better: yours or mine and pc's. Mine, because
it (a) follows devices that natlangs find useful, (b) preserves a
useful distinction between "ui" and "mi gleki", and (c) provides
a way of expressing certain emotions without making any truth-conditional
assertions that describe my emotional state.

Your position doesn't seem foolish, but it does seem the less profitable
one.

Fair enough, but do note that some semioticians make use of a distinction
between, inter alia, "symbol" and "index" (as subtypes of sign", and
part of our disagreement is that you take "ui" for a symbol and I take
it for more of an index.

I'm not trying to win an argument by terminological sleight of hand...

I dispute that this is correct, but even if it were there would not
be a direct causal connection. There would be an indirect causal
connection mediated by the rule "speak the truth".

I haven't agreed that UI has a truth value, but if you are happy with
what I said then presumably all we disagree about is what counts as
a truth value. Certainly "real" and "fake" are not to my mind the
same as "true" and "false".

I learn it from exposure to Lojbanistani culture. Even when not
engaging in communication or other interaction with others, my behaviour
is still culturally conditioned.
