Eleanor (Kristen Bell) and her new classmate Jianyu (Manny Jacinto) learn about Utilitarianism in Season 1, episode 5 of “The Good Place.”

In a sneak peek for the episode, titled “Category 55 Emergency Doomsday Crisis,” Chidi (William Jackson Harper) tells Eleanor and Jianyu that Utilitarianism is a theory in normative ethics that posits that “the correct choice is the one that causes the most good or pleasure and the least pain and suffering.”

Although Eleanor finds the theory easy to understand, Chidi points out that the theory also has its loopholes. “If all that matters is the sum total of ‘goodness,’ then you can justify any number of that actions, like torturing one innocent person to save a hundred or preemptive war,” Chidi explains.

Clearly, Chidi is doing his job as a teacher so well, since Jianyu understands the lesson for the day.  The faux Buddhist monk even manages to give a “relevant” example of Utilitarianism during the class. Watch the sneak peek below to find out Jianyu’s funny anecdote which pretty sums up what the theory is all about.

Meanwhile, in another sneak peek for the episode, Janet (D'Arcy Carden) pops out in front of Michael (Ted Danson) and Tahani (Jameela Jamil) to tell them that the neighborhood is facing a category 55 emergency doomsday crisis.

When Tahani asks what a category 55 emergency doomsday crisis is, Michael tries his best to hide his worries. “It’s nothing. It’s a tiny little convenience,” Michael tells Tahani, before adding: “Tahani, could you show us to a private room where no one could see or hear us even if I yell very loudly out of fear?”

Does the category 55 emergency doomsday crisis have something to do with the sinkhole that emerged at the end of last week’s episode? Only time will tell.

“The Good Place” Season 1, episode 5 airs Thursday, Oct. 6, at 8:30 p.m. on NBC.
