Tractatus Logico-Philosophicus
In short numbered propositions, the Tractatus sets out how language can represent the world: the world is the totality of facts, a proposition is a logical picture of a possible state of affairs, and logic shows the form that language and world share. Ethics, aesthetics and the meaning of life fall outside what can be said, and the book ends by calling its own propositions nonsensical, a ladder to be thrown away once climbed.
Understanding the text
Drafted in notebooks kept during his service in the Austro-Hungarian army from 1914 and completed in 1918, it appeared in German in 1921 and in a bilingual edition in 1922 with an introduction by Bertrand Russell that Wittgenstein felt misread it. It was the only philosophical book he published. Readers still dispute whether its nonsense conveys ineffable insights or is meant to dissolve itself completely.
Key points
- 01
Picture theory
A proposition represents a possible state of affairs by sharing its logical form; it is true when that state of affairs obtains and false when it does not.
- 02
Saying and showing
Logical form cannot be stated by a further proposition; it shows itself in the structure of the meaningful propositions we actually use.
- 03
Limits of language
What lies beyond the limits of sense, including value and the mystical, is not denied but passed over in silence, as the final proposition asks.

Following the arguments
Picture theory : A proposition represents a possible state of affairs by sharing its logical form; it is true when that state of affairs obtains and false when it does not. Saying and showing : Logical form cannot be stated by a further proposition; it shows itself in the structure of the meaningful propositions we actually use. Limits of language : What lies beyond the limits of sense, including value and the mystical, is not denied but passed over in silence, as the final proposition asks.

Questions to carry into your reading
- How does a picture share its form with what it represents?
- Why does the book call its own propositions nonsensical, and what follows for its reader?
A meaningful proposition pictures a possible fact; what makes such picturing possible can only show itself.
