"Why not? It is all the same thing. There is no inequality in the region of art; and I have seen things on the vaudeville stage which were graced with touches of truth so exquisite, so ideally fine, that I might have believed I was getting them at first hand and pure from the street-corner. Of course, the poor fellows who had caught them from life had done their worst to imprison them in false terms, to labor them out of shape, and build them up in acts where anything less precious would have been lost; but they survived all that and gladdened the soul. I realized that I should have been making a mistake if I had required any 'stunt' which embodied them to be altogether composed of touches of truth, of moments of life. We can stand only a very little radium; the captured sunshine burns with the fires that heat the summers of the farthest planets; and we cannot handle the miraculous substance as if it were mere mineral. A touch of truth is perhaps not only all we need, but all we can endure in any one example of art." "You are lucky if you get so much," we said, "even at a vaudeville show." "Or at an opera," he returned, and then the curtain rose on the second act. When it fell again, he resumed, as if he had been interrupted in the middle of a sentence. "What should you say was the supreme moment of this thing, or was the radioactive property, the very soul? Of course, it is there where Nemorino drinks the elixir and finds himself freed from Adina; when he bursts into the joyous song of liberation and gives that delightful caper 'Which signifies indifference, indifference, Which signifies indifference,' and which not uncommonly results from a philter composed entirely of claret. When Adina advances in the midst of his indifference and breaks into the lyrical lament 'Neppur mi guarda!' she expresses the mystery of the sex which can be best provoked to love by the sense of loss, and the vital spark of the opera is kindled. The rest is mere incorporative material. It has to be. In other conditions the soul may be disembodied, and we may have knowledge of it without the interposition of anything material; but if there are spiritual bodies as there are material bodies, still the soul may wrap itself from other souls and emit itself only in gleams. But putting all that aside, I should like to bet that the germ, the vital spark of the opera, felt itself life, felt itself flame, first of all in that exquisite moment of release which Nemorino's caper conveys. Till then it must have been rather blind groping, with nothing better in hand than that old, worn-out notion of a love-philter. What will you bet?" "We never bet," we virtuously replied. "We are principled against it in all cases where we feel sure of losing; though in this case we could never settle it, for both composer and librettist are dead."
