5.461 The apparently unimportant fact that logical pseudo-relations like v and [if…then] need brackets – in contrast to real relations – is of great importance [bedeutungsvoll].
The use of brackets with these seemingly primitive signs indicates [deutet] already indeed that these are not real primitive signs. And surely nobody is going to believe that brackets have an independent meaning.
OK, although brackets have a use, so have they as much meaning as anything else in logic? What would an “independent meaning” [eine selbständige Bedeutung] in logic be?
