Ulysses had himself bound to the mast and the ears of his sailors plugged with wax lest the ravishing strains of the sea nymphs' song reach their ears and cause them to cast themselves into the sea and into their doom.
But what song did the Sirens sing, and in what key? And what about the nymphs themselves? Were their tresses of golden hue? And how long were they? Were the nymphs equipped with special nautical brassieres to protect their tender nipples from rude contact with jelly fish and such?
One cannot sing a song without singing some definite song in some definite key commencing at some definite time and ending at some definite later time.
But you understand the story of Ulysses and the Sirens and you are now thinking about the song they sang. And you are thinking about the nymphs and their ravishing endowments. But what sorts of objects are these? Incomplete objects. Are there then in reality incomplete objects?
