Full Idea
In logic a drive rules, first of falsifying, and then of implementing a single viewpoint: logic does not originate in the will to truth.
Gist of Idea
Logic is not driven by truth, but desire for a simple single viewpoint

A Reaction
Presumably logic derives from a will to simplify rather than a will for truth. Ockham's Razor describes the essence of human thinking. Even if Nietzsche is right, there is still a desire that the simplified view should be true.
