“A good objection helps one forward, a shallow objection, even if it is valid, is wearisome. … The objection does not seize the matter by its root, where the life is, but so far outside that nothing can be rectified even if it is wrong. A good objection helps directly towards a solution, a shallow one must first be overcome and can, from then on, be left to one side. Just as a tree bends at a knot in the trunk in order to grow on.”
