Undergraduates today can select from a swathe of identity studies.... The shortcoming of all these para-academic programs is not that they concentrate on a given ethnic or geographical minority; it is that they encourage members of that minority to study themselves - thereby simultaneously negating the goals of a liberal education and reinforcing the sectarian and ghetto mentalities they purport to undermine.

Love, it seems to me, is that condition in which one is most contentedly oneself.

The different American experience of the 20th Century is crucial because the lesson of the century for Europe, which essentially is that the human condition is tragic, led it to have a build a welfare system and a set of laws and social arrangements that are more prophylactic than idealistic. It's not about building perfect futures; it's about preventing terrible pasts. I think that is something that Europeans in the second half of the 20th century knew in their bones and Americans never did, and it's one of the big differences between the two Western cultures.

The American financial and military commitment really only kicks in with Korea. Not that Korea was the real game for the Americans; their real fear was that this was just the prelude to a second Korea in Germany. We now know from the Soviet archives that the last thing Stalin was going to do was start a war in Central Europe. The Americans didn't know that, and it was the fear that he might which transformed NATO from a sort of shell game into a real military alliance. That total commitment basically transformed the Marshal Plan into military aid.

Yugoslavia served as a reminder that the lessons of World War Two were only partially learned. There's a great line someone wrote in the middle of the 1990s, at the time when Clinton was agonizing about whether or not to go into Bosnia: "Everyone says, 'Never again. Never again.' But all they really mean is never again will Germans kill Jews in the streets of Warsaw".

We are not merely historians but also and always citizens.

History can show you that it was one pile of bad stuff after another. It can also show you that there's been tremendous progress in knowledge, behaviour, laws, civilisation. It cannot show you that there was a meaning behind it.
