I know he liked to publicize the exchanges where he got the best of someone, and bury the others, and that he was a far, far cry from a public intellectual. Still, he talked to folks about ideas, and that's something that we should have more of.
That should be something that we strive for, but I fear we'll see it less and less. Who'se going to want to go around and argue with people now?
If you compare it with the more sober, reflectful sort (eg russell vs copleston on the existence of God [0]) you can see how far we've fallen.
Nevertheless, his killing I think will make us slide even further.
