What happens

    Occam's razor is not a pragmatic guideline; it is a logical truth that superfluous symbols are meaningless.

    Wittgenstein redefines Occam's razor as a principle of logical semantics.

  • Signs which serve one purpose are logically equivalent, signs which serve no purpose are logically meaningless.

    Signs that fulfill a function are logically interchangeable; signs without function are logically void.
