Длинная цитата из книги Harry Potter and the Methods of Rationality: “My own approach is usually to identify the different desires, give
them names, conceive of them as separate individuals, and let them argue it out inside my head. So far the main persistent ones are my Hufflepuff, Ravenclaw, Gryffindor, and Slytherin sides, my Inner Critic, and
my simulated copies of you, Neville, Draco, Professor McGonagall, Professor Flitwick, Professor Quirrell, Dad, Mum, Richard Feynman, and
Douglas Hofstadter.”
Hermione considered trying this before her Common Sense warned
that it might be a dangerous sort of thing to pretend. “There’s a copy of
me inside your head?”
“Of course there is!” Harry said. The boy suddenly looked a bit more
vulnerable. “You mean there isn’t a copy of me living in your head?”
There was, she realized; and not only that, it talked in Harry’s exact
voice.
“It’s rather unnerving now that I think about it,” said Hermione. “I do
have a copy of you living in my head. It’s talking to me right now using
your voice, arguing how this is perfectly normal.”
“Good,” Harry said seriously. “I mean, I don’t see how people could be
friends without that.”
