Indeed, to say that science objectifies is quite a generalization, especially since some sciences are "purer" or more abstract than others. I see the abstraction in theoretical physics and mathematics, though, as a step needed for more ambitious exploitations of nature. Theoretical physicists have resorted to such abstraction because testing their cosmological models has gotten very expensive and perhaps even unfeasible. Many physicists likely think naively that they're just after the ultimate, objective truth, the model that corresponds to reality. But that would be oxymoronic since all models simplify, and if scientists don't work with models, what exactly are they doing? Do scientists have mirrors of nature? Is that what reason or the scientific institution is? I think not.
