This blogpost is focused on looking at how Lethe, the sixth episode of Star Trek: Discovery fits into the events and themes of the previously established universe. I’ve written similar blogposts looking at each previous episode (you can read the first here, and the fifth here).
Science, Magic and Spirituality
Arthur C. Clarke famously claimed that “any sufficiently advanced technology is indistinguishable from magic”. The genres of science fiction and fantasy overlap a great deal in practice, with the ‘science’ in scifi being so advanced and unexplained that it may as well be magic. Star Trek has generally been more solidly scientific than Star Wars or Doctor Who, but there are beings like Q and the Squire of Gothos who are so highly evolved that they effectively play the same role the gods did in Greek mythology. On a smaller scale, an important part of series 6 of DS9 is the concept of ‘self-replicating mines’, which realistically would need to draw an enormous amount of energy from the vacuum of space in order to replace themselves. The scientific accuracy in any work of science fiction will be limited by the writers’ scientific knowledge and imagination, and the audience’s ability to understand. The story is more important than getting the jargon right, and that will mean some compromise.
Probably the most magical aspect of Star Trek mythos is the katra – the Vulcan idea of the soul. In The Wrath of Khan Spock incapacitates McCoy and instructs him to “remember” before entering Engineering to perform an operation which he knows will irradiate his body. After Spock ‘dies’ and his body is jettisoned, Kirk and crew learn that Spock’s katra is inside McCoy, prompting them to steal a ship to search for Spock’s body, and reunite it with his soul.
This potentially raises some interesting questions – what happens if Spock had survived the process, but had become separated from McCoy? Does this mean what’s probably the most iconic speech in the franchise (“The needs of the many” and “I have been and always shall be, your friend”) was delivered not by Spock, but by an empty husk, an echo of who he is? The location of Spock’s katra is either a plotpoint that we shouldn’t think about too much (like the self-replicating mines) or an interesting philosophical question.
