The world is the totality of facts, not of things.
What is the case, the fact, is the existence of atomic facts.
The logical picture of the facts is the thought.
The thought is the significant proposition.
The object of philosophy is the logical clarification of thoughts. Philosophy is not a theory but an activity.
Propositions are truth-functions of elementary propositions.
The limits of my language mean the limits of my world.
Not how the world is, is the mystical, but that it is.
There is indeed the inexpressible. This shows itself; it is the mystical.
My propositions are elucidatory in this way: he who understands me finally recognizes them as senseless, when he has climbed out through them, on them, over them.
He must so to speak throw away the ladder, after he has climbed up on it.
He must surmount these propositions; then he sees the world rightly.
Wovon man nicht sprechen kann, darüber muss man schweigen.
Whereof one cannot speak, thereof one must be silent.
