Object permanence is a myth. What we mistakenly think of as object permanence is actually a (sometimes useful) illusion generated by a mind-virus that evolved symbiotically with human cognition - in other words, a story.
Recognizing the narrative DNA of such things doesn't necessarily mean it's useful or even desirable to deconstruct them, though.
@mykola All that we experience is narrative. We are our minds, drawing conclusions from the sense data without and state within. We fill in gaps without notice all the time, and we all fill in different gaps in different proportion. We are all narratives, sets of beliefs about the world that we insufficiently validate or explore, because to do would be to invite the madness of never being capable of knowing who we are.
