RONRI.NET 論理 — the architecture of reason.
β

All valid arguments preserve truth from premises to conclusion.

∧

The structure of an argument, not its content, determines its validity.

γ
¬

To negate is not to destroy, but to reveal the boundary of a proposition. Every statement carries within it the shadow of its own contradiction — the unsaid that gives the said its shape. In formal logic, negation is the mirror: it shows us what a world without a given truth would look like.

δ

If the premises are true...

→

...and the argument form is valid...

→

...then the conclusion must be true.

∴ Reason endures.
