On the impossibility to find a consistent and unambiguous model of reality

The impossibility for us to find a consistent and unambiguous model of reality, such as the ideas of "a single true tree of life" (cladistics) and of "a single Grand Unifying Theory" (particle physics), is obviously not due to reality, but to our conceptualization itself (see Russell's paradox), although reality itself obviously has the same problem, since it can't stop. It means that a search for such ideas actually mimics reality instead of modeling it. Ironic, isn't it?
