Social democracy does not represent an ideal future; it does not even represent the ideal past.

We have responsibilities for others, not just across space but across time. We have responsibilities to people who came before us. They left us a world of institutions, ideas or possibilities for which we, in turn, owe them something. One of the things we owe them is not to squander them.

Obviously a primary liberal conviction is that we should be tolerant of other peoples' convictions. But if we believe in something, we had better find ways to say so convincingly.

Social democrats are characteristically modest - a political quality whose virtues are overestimated. We need to apologise a little less for our shortcomings and speak more assertively of achievements. That these were always incomplete should not trouble us.

I just like being on my own on trains, traveling. I spent all my pocket money travelling the London Underground and Southern Railway, what used to be the Western region, and in Europe as much as I could afford it. My parents used to think I was going places, but I wasn't, I was just travelling the trains.

The people whose necks hurt when I write about the Middle East tend to live in Brooklyn or Boca Raton: the kind of Zionist who pays another man to live in Israel for him. I have nothing but contempt for such people.
