I have just come in from Tristan and Isolde .
I had to hurry and be there for the first notes because you—my you—would, I felt, be sitting beside me as you have so often. That, of course, is passion—the passion that makes us unaccountable in our actions.
I found you naturally: but I found, too, something else. It has always a little puzzled me why we return to Tristan. There are passages in that thing as intolerable as anything in any of the Germanic master’s scores. But we are held—simply by the idea of the love-philtre: it’s that alone that interests us. We do not care about the initial amenities of Tristan and the prima donna: we do not believe in Mark’s psychologising: but, from the moment when those two dismal marionettes have drained unconsideringly the impossible cup, they become suddenly alive, and we see two human beings under the grip of a passion—acting as irrationally as I did when I promised my cabman five shillings to get me to the theatre in time for the opening bars.
It is, you see, the love-philtre that performs this miracle. It interests—it is real to us—because every human being knows what it is to act, irrationally, under the stress of some passion or other. We are drawn along irresistibly: we commit the predestined follies or the predestined heroisms: the other side of our being acts in contravention of all our rules of conduct or of intellect. Here, in Tristan, we see such madness justified with a concrete substance, a herb, a root. We see a vision of a state of mind in which morality no longer exists: we are given a respite, a rest: an interval in which no standard of conduct oppresses us. It is an idea of an appeal more universal than any other in which the tired imagination of humanity takes refuge.
