If you were given a two-year sabbatical to go off and study any subject of your choice, which one would you choose? Assume that you cannot pick a foreign language.
Once a language is removed, I'm not certain. Both psychology and philosophy are appealing. Although I've studied a lot of history, there is still so much more to learn. Narrower subjects, such as the French Revolution and the American Civil War, are very attractive.
Which way would you lean?
