The use of steam, electricity, wind, water and other involuntary forces in nature is dependent on the intelligence of an engineer. Our subconscious power cannot function without its own engineer-our conscious technique. It is only when an actor feels that his inner and outer life on the stage is flowing naturally and normally, in the circumstances that surround him, that the deeper sources of his subconscious gently open and from them come feelings we cannot always analyze. For a shorter or longer space of time they take possession of us whenever some inner instinct bids them. Since we do not understand this governing power and cannot study it, we actors call it simply nature. 16
