You can disagree with the premise, but this is the philosophy that underlies most of scientific method today.

Science is a series of propositions that happen to be useful. Gravity is a name: we can model in different ways. In one case it's an ever-present force emanating from a mass, in other cases it's a geodesic in spacetime. These are models to put our observations into simple elegant pictures.

Reality is composed only of instances of observations: not theories (and so, not forces, laws, particles, etc.). Theories are just a net we throw over observations to give them a gestalt overall picture: but it's not real, the same way constellations aren't real. It's a picture connecting dots.
