I wish to boast that Pygmalion has been an extremely successful play all over Europe and North America as well as at home. It is so intensely and deliberately didactic, and its subject is esteemed so dry, that I delight in throwing it at the heads of the wiseacres who repeat the parrot cry that art should never be didactic. It goes to prove my contention that art should never be anything else.
