Dear Professor Mihai Panoschi Panoschi,
I apologize for missing an honorific in my first response.
Thanks for replying and your thought provoking comments!
That said, yes I fully agree grammar and syntax play an important part in semantics of sentences and indeed cited Wittgenstein in my own work to advocate my stance, though I by no means claim your level of expertise or depth.
Having said that, in day to day conversation we rely on "informal" systems to communicate.
Unless you propose to reduce everything we have said to a formal system ( which is time consuming) than some degree of leniency on regards to grammar, and syntax is warranted, even in scholarly works.
That said, I am confused you attribute cause/effect to the sentence, "If it rains, the ground gets wet". Implication is not causation, something I remember being from my Discrete mathematics course. Let us attribute false value to the proposition p," it rains", and truth to the proposition ," the ground gets wet", the truth value for p implies q would still be true. However, a causal understanding would tell us a different scenario.
Again, thanks for your detailed critique and replying here!
All the best for this essay contest and researches! And, I suppose apologies for semantic ambiguity and resembling "naive wishful thinking".
Best Wishes,
Raiyan Reza
