The Hamlet Project

The ghost is all he, him, his – a person, Hamlet’s father in all his fatherly power and terror. And then suddenly – he is an it stealing away. I’m very curious about this transition from subject to object – from personhood to an “it” and an “it” that steals away, no less.
I assume that when Hamlet calls the Ghost “it” he is thinking of it as “ghost,” as the thing he is and when he calls him “he” or “my father,” he is thinking of him that way. Perhaps it functions as a kind of reminder to himself that the ghost is the ghost of his father and not his actual father. Maybe. I’m just curious about it.
From he to it. That’s our journey, huh?
