Key passages
“Tautology and contradiction are not pictures of the reality.”
Neither tautologies nor contradictions depict how things are in the world.
They fail to represent any possible state of affairs.
“For the one allows every possible state of affairs, the other none.”
A tautology is compatible with all situations, while a contradiction excludes all.
This highlights their lack of factual content.
