We know now that the soul is the body, and the body the soul. They tell us they are different because they want to persuade us that we can keep our souls if we let them make slaves of our bodies.
George Bernard ShawWhen you want to put something into your part that is not in the play, you must ask the author-or some other author-to lead up to the interpolation for you. Never forget that the effect of a line may depend not on its delivery, but on something said earlier in the play, either by somebody else or by yourself, and that if you change it, it may be necessary to change the whole first act as well.
George Bernard Shaw
