Key passages

  • The mark of logical propositions is not their general validity. To be general is only to be accidentally valid for all things. An ungeneralized proposition can be tautologous just as well as a generalized one.

    What makes a proposition logical is not that it applies to everything, since that is just a contingent feature; even a specific proposition can be a tautology.

    Clarifies that generality is not the essence of logical truth.
