    I think you lapse into dataSpeak or systemSpeak when you say “Thus, every proposition has a truth-value.” According to the Merriam-Webster definition you quote, every proposition “… *is* either true or false”. (If a proposition is true, it’s a fact.) The semantics of “is” vs. “has” of course are distinct.
    Nice piece. My comment is from the perspective of SBVR, which is a linguistic standard. What would be really interesting is a piece on data vs. information vs. knowledge.

      Perhaps. It was a setup for the next sentence, which says that “propositional logic . . . studies the truth-value of propositions.”
      Knowledge is a deep subject, but I could give it a try in a future blog.
