I agree with that. But the conclusion is very interesting. If something cannot be expessed within a language, it also cannot be described used any formal system, or mathematics in general. Which should be very distrurbing to modern naturalists, to whom (to the first approximation) everything is just clouds of particles (whose behavior can be described using mathematics).
