Massimo Pigliucci in Footnotes to Plato:
Episode five of the second season of TGP features a sophisticated discussion of the infamous trolley problem, a thought experiment in ethics that has by now generated a cottage industry among both philosophers and neuroscientists. I will not explain for the n-th time what the problem consists of, you can look it up on Wikipedia. Suffice to say that the more I study virtue ethics, the more I become skeptical of the value of much modern moral philosophy, with its indulging in more and more convoluted hypothetical situations that seem to be designed more to show off the cleverness of the people working in the field than to actually help the rest of us live an ethical life. It is no coincidence that the dilemma is always framed in terms of what a deontologist or a utilitarian would do, those two frameworks having gotten further and further away from any relevance to real life, contra to what either Immanuel Kant or John Stuart Mill surely intended.
At any rate, the episode in question features a theoretical lecture on trolleys by the resident philosophical character, Chidi (played by the excellent William Jackson Harper). One of those on the receiving end of the lecture is the demon-turning-good-guy Michael (played by the awesome Ted Danson). During the lecture, Michael becomes impatient with the theory, so he snaps his fingers and transports Chidi, his friend Eleanor (played by Kristen Bell) and himself aboard an actual trolley, about to kill what appear to be real people. Michael then asks Chidi for a real-life demonstration: what is the philosopher going to do when suddenly faced with the dilemma, in the field, so to speak? Hilarity (and mayhem) quickly ensue. The episode is so good that I made my students watch it and comment on it.
