This quote from Thornton Wilder tells us that our hearts know and have their own consciousness. It seems that our hearts and not our brain are really the ones that know about our true self. Even St. Exupery talked about seeing with the heart and now Wilder talks about being conscious with the heart.
By the way, Thornton Wilder is an American play write who won three Pulitzer Prizes for a novel and two plays.
