This view, that our actors have become more worthy of respect than heretofore, does not imply that I believe them to have become less dangerous.… But who is in any doubt as to what I want,—as to what the three requisitions are concerning which my wrath and my care and love of art, have made me open my mouth on this occasion?

That the stage should not become master of the arts.

That the actor should not become the corrupter of the genuine.

That music should not become an art of lying.

Friedrich Nietzsche.
