# Negation Elimination

Like the [introduction](/Logic/Proofs/Negation_Introduction.md) rule for
|
|
|
|
|
negation, the elimination rule also works by deriving a contradiction. It is
|
|
|
|
|
basically _Negation Introduction_ in reverse. Instead of starting the sub-proof
|
|
|
|
|
with a true proposition from which you derive a contradiction, you start with
|
|
|
|
|
the negation of a proposition, derive a contradiction and then assert the
|
|
|
|
|
positive of the negated proposition you started out with.
