Definition: the True Language is so named not because it satisfies the concept from antiquity of a language whose expressions were naturally isomorphic to their referents in some essentialistic way, but because each letter in the metaphorical True Alphabet is made up of acts of virtue and grace, the crystallization of sincerity. It might not be real, for all I know, despite humanity's tendency to symbolism and indirect communication. However, for now we will just be asking about a general possibility.
Question: suppose some long-term moral timeline, an ethical metanarrative involving many people in many places at many times. Since per the definition, the True Language can carry any expression, there would be True sentences that were questions because they were bracketed by actions symbolic of ¿ and ?. Or, then, would that be the only way to mark out a True question? In real language, we can use inflection to help gesture at the interrogative mood, and though it is dimly imaginable that there could be dialects of the True Language, perhaps it would simply be easier to have a designated action playing the role of the question mark. Supposing that all good deeds done in this timeline could be construed as spelling out a single massive "sentence," would it be possible for someone to close the given moral timeline by performing the second question-mark act?
