Le premier commentaire en fait. Sans oublier, surtout, la dernière phrase.

When faced with an awkward question, logical positivism asks: what would the answer tell me about the future?

Suppose you had a definitive, 100% guaranteed answer to the "discovered vs invented" question. What would it allow you to do that you couldn't do before? What could you predict? What would you gain?

Nothing, nothing and nothing.

It's meaningless; merely a matter of perception, wordplay and people having too much time on their hands.
Oh, and the correct answer is "discovered".
