Wittgenstein's Tractatus


1. The World and Facts
The world consists of a collection of logically independent facts. If you know all the facts, you know all there is to know.

3. Propositions express Pictures

5. Truth Functions
2. Logico-Pictorial Models
A state-of-affairs is a combination of simple objects and either exists or not. States of affairs are logically independent of each other and their sum total is the world. A picture models a state of affairs because its elements correspond to the objects in the state of affairs and it has the same logical form.

4. The Content and Form of Propositions

6. From Logic to the Ineffable
Via mathematics, science and value judgements.

7. The Ineffable
About which, 'nuff said.
