# Bertrand Russel

* Wittgenstein was his protege
* Co-Founder of analytic philosophy
* theory of descriptions
  * about wheter a sentence like 'the current king of france is gray' is true, false or meaningless
  * he says it means: one king of france exists and he is gray.
  * so there can't be empty identities
    * if no king of france exists, the sentence is simply false

# Early Wittgenstein

* Student and Friend of Russel
* early work named The Tractatus
* a simple statement pictures a state of affairs (Sachlage) about simple objects
* a simple statement is true if state of affairs exists
* complex statements are with *and*, *or* and *not* compound simple statements
* statements which not fit in this are nonsensical
* most philosophical views are nonsensical

      *It ain’t what you say, it’s the way that you say it, and the context in which you say it.
      Words are how you use them.*
