“Very roughly, the drama may be called that part of theatrical art which lends itself most readily to intellectual discussion; what is left is theater. Drama is immensely durable; after a thousand critical disputes, it is still there, undiminished, ready for the next wranglers. Theater is magical and evanescent; examine it closely and it turns into tricks of lighting, or the grace of a particular gesture, or the tone of a voice–and these are not its substance, but the rubbish that is left when magic has departed. Theater is the response, the echo, which drama awakens within us when we see it on the stage.”
Robertson Davies, A Voice from the Attic
