Absolutely brilliant.
This class was everything that I've wanted out of Columbia. Professor Margalit is incredibly engaging. His classroom is dynamic-- you will never get bored. He constantly challenges you to clarify your thinking in ways that most professors wouldn't. Furthermore, you will learn a ton.
Professor Margalit really cares about his students. He goes out of his way to construct a syllabus that will encourage critical thinking and allow you to gain valuable skills. That said, he can be a little cold about deadlines. Also, he is pretty unresponsive to e-mails. Nonetheless, he gives far more of a shit than almost any professor I've had at Columbia. He obviously loves to teach, and it shows in the classroom.
This class was really great. Everyone in the class seemed to agree that they had enjoyed the ride.
A few random notes: If you are skeptical about taking this class because you are afraid of Yotam being a hard-line Zionist or something, leave your fears--and stereotypes-- at the door. Also, I will say this: a lot of the texts in this class do argue against conservatism; nonetheless, this may be the only political science class that assigns Hayek. Finally, this class focuses heavily American examples, so don't expect to be talking about Left and Right in Europe (or in any developing countries for that matter) very extensively.
