" But even Wagner, with his magnificent music and his rather less worthy pseudo-medieval words, is never wholly successful. Why? Because a work of art must be in some measure coherent; but thought and feeling mingled, as all of us experience them, are surging and incoherent. Thought and feeling trimmed into coherence in a work of art are still far from reality, still far from the agonizing confusion that rises like miasma in what a great poet has called the foul rag-and-bone shop of the heart. "

― Robertson Davies , Murther and Walking Spirits (Toronto Trilogy, #1)
