Characters to notice

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.
