Full Idea
If truth were nothing more than lack of contradiction, one would have to examine first of all, with regard to each concept, whether it does not on its own account, contain an inner contradiction.
Gist of Idea
If truth is just non-contradiction, we must take care that our basic concepts aren't contradictory

A Reaction
This is a very nice thought, which modern analytic philosophers, steeped in logic, should think about. It is always presumed that a contradiction is between a proposition and its negation, not some inner feature.
