… Čapek reflected on the origin of one of the play’s characters:
The old inventor, Mr. Rossum (whose name translated into English signifies “Mr. Intellectual” or “Mr. Brain”), is a typical representative of the scientific materialism of the last [nineteenth] century. His desire to create an artificial man — in the chemical and biological, not mechanical sense — is inspired by a foolish and obstinate wish to prove God to be unnecessary and absurd. Young Rossum is the modern scientist, untroubled by metaphysical ideas; scientific experiment is to him the road to industrial production. He is not concerned to prove, but to manufacture.
