"What man has joined, nature is powerless to put asunder."

his phrase, spoken by the Director, plays on the common phrase during a marriage ceremony - "What God has joined, let no man put asunder." In the marriage ceremony, the phrase evokes God's foreknowledge of bringing two persons together in love. In this quote, the Director claims the supremacy of science and progress. Man, not a god or nature, has put together the human body and mind, essentially conquering nature.
