In our analysis of Star Trek II: The Wrath of Khan, we join Admiral James T. Kirk and his Starfleet friends as they are once again pulled into a risky adventure. Since his infamous attempted coup on the Enterprise 15 years ago, Khan Noonien Singh is noticeably more emotional, ragged from years of hard survivorship on an inhospitable planet, but he's also deeply preoccupied with revenge. But as both the film and science can attest, achieving revenge is rarely as satisfying or as personally rewarding as we hope it will be.

When the survival of the whole planet is at stake, how much do purpose, logic, wisdom, and emotion matter? Do we rely on gut instincts or unfiltered logic to make critical decisions? The original cast of Star Trek reunite to represent the voyages of the Starship Enterprise in their first film, Star Trek: The Motion Picture (1979). Dr. Drea especially observes the internal struggle building within Spock, who is recently rejected by his Vulcan community due to his inability to suppress emotions to an extreme degree as his culture dictates; his elders chastise him for allowing feelings like yearning, friendship, and exhilaration to distract or break his mental discipline.
