WHY SHAKESPEARE MATTERS ...

In Shakespeare the birds sing, the bushes are clothed with green, hearts love, souls suffer, the cloud wanders, it is hot, it is cold, night falls, time passes, forests and multitudes speak, the vast eternal dream hovers over all. Sap and blood, all forms of the multiple reality, actions and ideas, man and humanity, the living and the life, solitudes, cities, religions, diamonds and pearls, dung-hills and charnel houses, the ebb and flow of beings, the steps of comers and goers, all, all are on Shakespeare and in Shakespeare.
Victor Hugo

He is as a mountain, whose majesty and multitudinous beauty, meaning, and magnitude and impress, must be gotten by slow processes in journeying about it through many days. Who sits under its pines at noon, lies beside its streams for rest, walks under its lengthening shadows as under a cloud, and has listened to the voices of its water falls, thrilling the night and calling to the spacious firmament as if with intent to be heard "very far off," has thus learned the mountain, vast of girth, kingly in altitude, perpetual in sovereignty. We study a world's circumference by segments; nor let us suppose we can do other by this cosmopolitan Shakespeare. He, so far as touches our earth horizon, is ubiquitous. Looking at him sum-totally, we feel his mass, and say we have looked upon majesty.
William A. Quayle
