Five happy Moon's sang the Macarena. Truth is beauty. There is nothing grammatically wrong with those sentences, there is no way to philosophically disprove them, and they have nothing to do with the physical world around us.
PS: I am not saying philosophy is useless, just it's a search for something other than meaning... perhaps truth. ;)
Disregarding the fact that there actually _was_ something grammatically wrong with that sentence, I think that is a misconception of philosophy. It's not supposed to prove or disprove much (except in certain areas dedicated to logic perhaps). I don't see philosophical arguments as meaningless, and to claim so is to make a very philosophical claim ... What is meaning anyway? I don't think anybody really knows the answer to that. But perhaps you meant to say that these arguments won't lead to any concrete results, and there I'd have to agree with you.
