We are lucky in the United States to have our liberal arts system. In most countries, if you go to university, you have to decide for all English literature or no literature, all philosophy or no philosophy. But we have a system that is one part general education and one part specialization. If your parents say you've got to major in computer science, you can do that. But you can also take general education courses in the humanities, and usually you have to.

With the rise of capitalism, it became more obvious that people pursue individual self-interest. The great nationalist in Italy, Giuseppe Mazzini, a wonderful philosopher, said that we need the nation. We need something that people can lean on, from which they can then reach out to the whole world. The idea of all humanity is too vague. It can't motivate human aspiration in a reliable way.

Life is about more than earning a living, and if you're not in the habit of thinking about it, you can end up middle-aged or even older and shocked to realize that your life seems empty.

The humanities prepare students to be good citizens and help them understand a complicated, interlocking world. The humanities teach us critical thinking, how to analyze arguments, and how to imagine life from the point of view of someone unlike yourself.

The great philosophers of the past who wrote so beautifully - Rousseau, John Stuart Mill - had to write beautifully because they had to sell their work to journals. They had to sell books to the general public because they could not hold positions in universities. Mill was an atheist, and, therefore, could not hold a position in a university.

There was a time, before I was in graduate school, when political philosophy pretty much ceased to exist. The positivists thought there were only two things you could do: conceptual analysis or empirical investigation. Any kind of political theory or even ethical theory was nonsense.
