" 1. The world is everything that is the case.
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.
5. A proposition is a truth-function of elementary propositions. (An elementary proposition is a truth-function of itself.)
6. The general form of a proposition is the general form of a truth function, which is: [p, E, N(E)]. This is the general form of a proposition.
7. Whereof one cannot speak, thereof one must be silent. "
― Ludwig Wittgenstein , Tractatus Logico-Philosophicus
