TED:Michael Sandel: What's the right thing to do?

 In these days, I read a book‘Justice’ which is very hard to understand his real intention. The book is based on a course Sandel teaches at Harvard. More than 14,000 students have taken the course, making it one of the most highly attended in Harvard's history. Sandel explains theories of justice based on utilitarianism (minimize social harm), libertarianism (maximize personal freedom) and communitarianism (cultivate civic virtue). When I was a high school student, I learned the theories in ‘윤리’ classes. As a result, I can read easier than friends who didn’t study ‘윤리’. We can read the ideas of Aristotle, Jeremy Bentham, Immanuel Kant, John Stuart Mill, Robert Nozick and John Rawls.
