Teach him a certain refinement in sorting out and selecting his arguments, with an affection for relevance and so for brevity. Above all let him be taught to throw down his arms and surrender to truth as soon as he perceives it, whether the truth is born at his rival's doing or within himself from some change in his ideas.
Michel de MontaigneThe laws keep up their credit, not by being just, but because they are laws; 'tis the mystic foundation of their authority; they have no other, and it well answers their purpose. They are often made by fools; still oftener by men who, out of hatred to equality, fail in equity; but always by men, vain and irresolute authors.
