"Logic" by Georg Wilhelm Friedrich Hegel,1812

..
What is real is rational,and what is rational is real.
.
Logic,which is a systematic creative process,has three stages :
the abstract stage,
the dialectical stage,and
the speculative stage.
.
In the abstract stage terms of thought are considered separately ;
in the dialectical stage one realizes that for something to exist it must be,not separate,but in relation to others ; and
in the speculative stage one understands the unity of opposites in their opposition.
.
There are three subdivisions of logic :
the Doctrine of Being,
the Doctrine of Essence,and
the Doctrine of Idea
-by which being is known not only for itself and for another,but in-and-for itself.
