I feel like my 50 years at Harvard were an interlude. I'm really a New Yorker.

The struggle for morality never stays won. It's always in process.

The very concept of an Iranian university is an oxymoron. There are no free and open places of learning in that repressive theocracy. Dissenters are not given tenure; they are murdered, after first being tortured. Blasphemy, which is broadly defined, is punished. Gays are not only excluded from Iranian universities, but are imprisoned and killed.

I read in the newspaper that the Catholic Church finally decided that it had been theologically improper to try to convert the Jews. Whoops! Sorry for all those inquisitions, crusades, and autos-da-fe. Previous popes were wrong - infallible, perhaps, but wrong.

Good character consists of recognizing the selfishness that inheres in each of us and trying to balance it against the altruism to which we should all aspire. It is a difficult balance to strike, but no definition of goodness can be complete without it.

Foolish liberals who are trying to read the Second Amendment out of the constitution by claiming it's not an individual right or that it's too much of a safety hazard don't see the danger of the big picture. They're courting disaster by encouraging others to use this same means to eliminate portions of the Constitution they don't like.

Scientists search for truth. Philosophers search for morality. A criminal trial searches for only one result: proof beyond a reasonable doubt.
