I find this thread to be thought-provoking. The last unexamined belief I had was that James T. Kirk was an honorable man and honorable men do not abandon their children. So, for a long time, I took it for granted that Carol kept it a secret and Kirk was blamessly off the hook.
Over the years, I’ve modified my beliefs about agency, parenting, and integrity. Honor—as I understood it—is not the simplistic virtue I once held; neither are the choices made by these parents incompatible with integrity. On the contrary, Carol summed it up nicely when she said “You had your world and I had mine. And I wanted him in mine.” Kirk acceded to her wishes and life went on.
I was 13 when I saw TWOK at the theater. Precocious, Roman Catholic, and ripely adolescent, I saw Kirk as I would a father figure, as someone to take as a model. These discussions, as tedious as they might seem, have been tremendously helpful for me. Much of what formed me bears some examination.
ETA: In consequence, I changed my vote. Clever feature, that.
