    Earlier this month, the University of Glasgow in Scotland launched a course entitled: The Simpsons Introduce Philosophy(哲学). The course's aim is to ease students into the typically heavy topic by relating it to the popular cartoon family.

    “The Simpsons is one of the modem world's greatest cultural products, partly because it is so full of philosophy,” John Donaldson, creator of the course, told the BBC. “Aristotle, Kant, Marx, Camus and many other great thinkers' ideas are represented in what is arguably the purest of philosophical forms — the comic cartoon.”

    While this may seem like an unusual way to attract pupils to a traditionally dull topic, this class isn't the first of its kind. In 2009, Liverpool Hope University in the UK began offering a master's degree on the music of world-famous 60's group The Beatles, which still runs today. The following year, the UK's Durham University gave students the chance to enroll on a Harry Potter-themed module, covering contents such as “Gryffindor and Slytherin: prejudice and intolerance in the classroom,” and “muggles and magic”.

    To some, these courses may seem like a waste of a valuable education, but Donaldson believes that packaging certain topics into something more easy to relate to will enhance the learning experience, without distracting(分离)from the main subject. “Firstly, scholars want to be taken seriously by other scholars and ideas like this can be seen as not serious,” he tells iNews. “There are definitely ways to include popular culture into academic subjects that still remains their nature and doesn't take away from the quality of the ideas,”

    Already booked full, Donaldson's Simpsons class isn't meant to be taken as seriously, however. The lecturer says that his one-day course, which will pose philosophical questions around morality, free will, and religion by relating them to scenarios(情节)from The Simpsons, aims to introduce students to his area of expertise greatly while having a bit of fun.
