As recently as the 1970s, the idea that the point of life was to get rich and that governments existed to facilitate this would have been ridiculed: not only by capitalism's traditional critics but also by many of its staunchest defenders.

Contrast 1968, when the CEO of General Motors took home, in pay and benefits, about sixty-six times the amount paid to a typical GM worker. Today the CEO of Wal-Mart earns nine hundred times the wages of his average employee. Indeed, the wealth of the Wal-Mart founder's family in 2005 was estimated at about the same ($90 billion) as that of the bottom 40% of the US population: 120 million people.

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.

Words can make the illness a subject I can master, and not one that one simply emotes over.

My generation those who were students in the late 60s was always, in the words of the Who, talking about our generation. That's what we thought of ourselves, as the most important thing since sliced bread. And the "we" that we meant was really the Western Europeans and American generation. And as I think back I suppose I have a sense of guilt on behalf of my generation, a sense that we were terribly provincial and didn't understand the really important stuff that was going on in Eastern Europe.

It might be thought the height of poor taste to ascribe good fortune to a healthy man with a young family struck down at the age of sixty by an incurable degenerative disorder from which he must shortly die. But there is more than one sort of luck. To fall prey to a motor neuron disease is surely to have offended the Gods at some point, and there is nothing more to be said. But if you must suffer thus, better to have a well-stocked head.

I've lost count of the interviews I've done about my illness and its relationship to my ideas and writing.
