Key passages
“What signifies in the symbol is what is common to all those symbols by which it can be replaced according to the rules of logical syntax.”
The meaning of a symbol is determined by the invariant core shared by all symbols that can substitute for it under the laws of logical grammar.
Wittgenstein emphasizes that a symbol's significance lies not in its specific form but in the common feature preserved through permissible replacements.
