  2. What is the case (a fact) is the existence of states of affairs.
  3. A logical picture of facts is a thought.
  4. A thought is a proposition with a sense. (An elementary proposition is a truth-function of itself.)
  5. A proposition is a truth-function of elementary propositions.
  6. The general form of a proposition is the general form of a truth function. (formula given) This is the general form of a proposition.
  7. Whereof one cannot speak, thereof one must be silent.
