Realism
Physics looks at the world through the eyeglasses of physics. It cannot do more — although sometimes it seems to want more. Which, no doubt, is its right, even its duty. For ultimately it does not matter what theory says, but only what really happens. Nevertheless, to reason from this that there were something like the one objective reality beyond any such visual aid would mean to overshoot the mark. And, above all, sometime precisely this idea may mislead to give up — if not to forbid — the struggle for objectivity and reality or truth.
After all there is nothing to be said against the assumption that every reality is a certain view of reality. Reality is always a reflected, a known. Something else cannot be ascertained, not with the best will in the world — so then, why should it be there? And, actually — what should it be?
