Captain’s Log: Stardate 201704.11. The City on the Edge of Forever is easily one of the most compelling episodes of the original series, and we watch and analyze it in my class. According to Sara O’Hare, Nietzsche would describe Kirk as a Tragic Hero, whose private relationship, not to mention his happiness, must be sacrificed for the public good (to save humanity), whereas Spock is the Apollonian figure who represents logic and rational thinking, and McCoy is the chaotic, emotional Dionysian figure who must be stopped from saving Edith Keeler to prevent a chain reaction that will cause the Nazis to win World War II. A fan favourite and one of mine too. Below is a public domain photo of William Shatner as Kirk, although it is not from this episode.
