## Character check-ins

### Mr. Wittgenstein

Author of the proposition, presenting the view on logical propositions.

## Key lines

> All propositions of logic are of equal rank; there are not some which are essentially primitive and others deduced from there.

No logical proposition is more fundamental than any other; none are primitive or derived.

_Rejects hierarchical views of logical truths._

> Every tautology itself shows that it is a tautology.

Each tautology is self-evidently tautological without needing external proof.

_Tautologies are self-justifying._
