Key passages
“If a sign is not necessary then it is meaningless. That is the meaning of Occam’s razor.”
A symbol that serves no essential function in the logical system is devoid of sense; this is the core insight of Occam's razor.
Wittgenstein redefines Occam's razor as a logical principle about the necessity of signs.
“(If everything in the symbolism works as though a sign had meaning, then it has meaning.)”
If a sign behaves in the symbolic system exactly as if it were meaningful, then it is meaningful.
Meaning is determined by functional role within the symbolism, not by external reference.
