In order to clear things up, the rules of Sentential Logic apply if and only if you are dealing with declarative sentences. If you bothered to read your Logic textbooks, you'd note that they all have very similar caveats when describing the limitations of Logical Grammar:
University of Manchester Department of Linguistics wrote:I shall ignore some more obvious and less fundamental divergencies from logical grammar, such as appear in questions, exclamations, commands, etc., and concentrate on declarative sentences ('statements'). The indicative element, which is essential to every sentence, is explicit here. With regard to statements, the tendency has been to say that, although they do not always exactly conform to logical grammar, they do so "roughly". From Aristotle to the present day, most failures in the exploration of ordinary language and thought appear to be due to this assumption.
Approaching the analysis of language, living language, with that dogmatic assumption, we shall always be left with a huge residue - really the vast majority of linguistic facts -unaccounted for; and ordinary language, instead of disclosing its own system and structure, is made to appear "unsystematic" and "logically imperfect".13 In fact, what is here considered to be an imperfection of language is due to the inadequacy of a preconceived interpretative scheme. Ordinary usage fails to exhibit the kind of system that logical grammar would elicit from it.
Right. If you, even for a second, attempt to apply rules of standard Sentential Logic to a question, such as "Since you are a monk, don't you have Wisdom bonus to AC?", your result is meaningless.
If you, even for a second, attempt to apply the rules of standard Sentential Logic to an exclamation, such as "I want to add my Wisdom Modifier to my AC!", your result is meaningless.
If you, even for a second, attempt to apply the rules of standard Sentential Logic to a command, such as "If you are a monk, add your Wisdom modifier to your AC.", your result is meaningless.
Got it?
