All poetry is of the nature of soliloquy. It may be said that poetry which is printed on hot-pressed paper and sold at a bookseller’s shop, is a soliloquy in full dress, and on the stage. It is so; but there is nothing absurd in the idea of such a mode of soliloquizing. What we have said to ourselves, we may tell to others afterwards; what we have said or done in solitude, we may voluntarily reproduce when we know that other eyes are upon us. But no trace of consciousness that any eyes are upon us must be visible in the work itself. The actor knows that there is an audience present; but if he acts as though he knew it, he acts ill.2
