There can be but one law; the unity of law results from the unity of essence: Nature and Art are the two slopes of the same fact. And in principle, saving the restriction which we shall indicate very shortly, the law of one is the law of the other. The angle of reflection equals the angle of incidence. All being equity in the moral order, and equilibrium in the material order, all is equation in the intellectual order. The binomial, that marvel adjustable to everything, is included in poetry no less than in algebra. Nature plus humanity, raised to the second power, give Art. Such is the intellectual binomial.
William Shakespeare by Victor Hugo
