FOUR decades ago, when the starship Enterprise first settled into orbit around Planet M-113 on Sept. 8, 1966, I was 2 years old. I could not have known it at the time, but “Star Trek” would literally change my life.

To say that any television show has changed one’s life is to invite both mockery and pity for a poor, shuttered geek who must surely have been denied direct sunlight and the attention of women for the better part of his days. But in lieu of offering documentary proof that I do not, in fact, still reside in my parents’ basement, let me simply tell you how “Star Trek” informed the way I look at the world.

“Star Trek” is often reduced to kitsch: Kirk’s paunch, Spock’s pointy ears, green-skinned alien girls. But it was more than escapism and rubber-suited aliens. It was a morality play, with Capt. James T. Kirk as a futuristic John F. Kennedy piloting a warp-driven PT-109 through the far reaches of the galaxy.

Kirk, for me, embodied an American idea: His mission was to explore the final frontier, not to conquer it. He was moral without moralizing. Week after week, he confronted the specters of intolerance and injustice, and week after week found a way to defeat them without ever becoming them. Jim Kirk may have beat up his share of bad guys, but you could never imagine him torturing them.
