An example of a metaphor used is discussing science:
"…a quantum-mechanical description is always relative to the particular user of of quantum mechanics who provides that description. Replacing that user with an apparatus introduces the notoriously ill-defined 'shifty split' of the world into quantum and classical, that John Bell so elegantly and correctly deplored.
Bell's split is shifty in two respects. Its character is not fixed. It can be the Landau-Lifshitz split between 'classical' and 'quantum'. But sometimes it is a split between 'macroscopic and microscopic'. Or between 'irreversible' and 'reversible'. The split is also shifty because its location can freely be moved along the path between whatever poles have been used to characterise it."
