@wayne,
W can say "objectivity" is relative to context.
We are saying that the word "objectivity"
never arises except in cases of lack of consensus. The artificial context of the philosophy discussion does not count. In normal situations you and I normally agree on what constitutes " an object", because we have coincident physiological and psychological needs.
Look at the
dynamic nuances of consensus and context here:
Croc Dundee's Girlfiend: Watch out Mick, he's got a knife !
Dundee: That's not a knife...(producing his own oversize one)..That's a knife !
Philosophers who argue about "what an object called a knife" IS are playing non-contextual games.
