" Analysis shows that when activities like playing the piano, writing or even walking are subjected to neurotic inhibitions it is because the physical organs brought into play—the fingers or the legs—have become too strongly erotized. It has been discovered as a general fact that the ego-function of an organ is impaired if its erotogenicity — its sexual significance — is increased. It behaves, if I may be allowed a rather absurd analogy, like a maid-servant who refuses to go on cooking because her master has started a love-affair with her. "
