First paragraph: It is a central claim of the Tractatus that a proposition “contains the possibility of the state of affairs it represents” (TLP §2.203). This essay seeks to understand this claim, and so to understand why “we cannot think anything unlogical” (TLP §3.03), why “it is impossible to judge a nonsense” (TLP §5.5422).
