"[...] reality is a metaphysical concept — it lies beyond the grasp of science. When we adopt specific beliefs about reality, what we are actually doing is adopting a specific philosophical position
There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.
This ‘working model’ of science acknowledges that reality-in-itself is metaphysical, that the objects of scientific study are the shadows, the things-as-they-appear or things-as-they-are-measured. It accepts that the facts that scientists work with are not theory-neutral — they do not come completely free from contamination by theoretical concepts. It accepts that theories are in their turn populated by metaphysical concepts and mathematical abstractions and are derived by any method that works, from induction to the most extreme speculation. It acknowledges that theories can never be accepted as the ultimate truth. Instead, they are accepted as possessing a high truth-likeness or verisimilitude — they correspond to the facts. In this way they become part of the authorized version of empirical reality. Finally, the model acknowledges the important role played by the Copernican attitude. Science works best when we resist the temptation to see ourselves as the primary objective or purpose of reality" -- Jim Baggott, Farewell to Reality
