The episode when broadcast in the United States was viewed by 16.54 million people and received mixed reviews from critics. It is the first episode to feature a 'Previously on Lost' segment, a clip shown at the beginning of each episode summarizing the recent events of the show. The episode receives its name from the philosophical idea of tabula rasa, meaning blank slate, a concept which is brought in one of the episode's final lines, when Jack tells Kate that all of the Flight 815 survivors should be allowed to restart with a new life.
