5.47321 Occam’s razor is of course not an arbitrary rule, or one justified by its practical success: it says that unnecessary symbolic units mean nothing [nichts bedeuten].

Signs in logic, and that is where signs live, have bedeutung only so far as they do something. And what they do depends on arbitrary conventions, definitions, etc.
