Well, this could be explained in a few meta-principles or just principles of a proper (non-abstract) philosophy.

1. A map is not a territory. Weighted connections are not semantic relations.

2. Environment and its laws and constraints comes first.

3. Language is a tool of describing What Is, not a tool of producing what could be.

4. Like untyped lambda calculus, applying anything to anything produce bullshit.

5. A proper use of a language require a type discipline which reflect the laws and constraints of the environment, and reject sentences with is not type-correct.

Everything else will produce a bullshit. Theoretical physics and other abstraction based fields are thus flawed.
