Hamilton – I disagree with him much more than I agree with him. This book is very much a book about a father and a son. The father is painted as the bad guy, and the son is the good guy, struggling to break free. I don’t accept that interpretation, or that framework of analysis. Nonetheless, Hamilton writes with a verve, an electricity, a passion, that’s rare among academic historians. As a researcher, he’s extraordinary.

This is an odd choice because I disagree with almost all his conclusions. He argues that the reign of Augustus sees the Roman élite finally dealing with the problems of the Greek culture that they love and the nasty Greeks they rule. He’s just wrong. They don’t. They carry on loving the culture and despising Greeks. I don’t agree with his methods. He doesn’t argue things. He just tells you stuff.

That’s where I disagree with her. I don’t actually think happiness is a meaning of life, though lots of people assume that. Still, happiness is something folks care about, and she gives the best discussion I know, of the nature of happiness and the ways that one can practically accomplish it.

I don’t think there is a better journalist than Hitchens writing in English. The power of his arguments – they’re so crisply written, they’re so forceful that, if you are on the other side, they almost strangle you. There’s nobody more compelling to read. Every time I read him, I learn something from him. His arguments are so tight, they’re hermetic. It’s very difficult to take them apart. I certainly don’t agree with him a lot of the time, but you can’t but be in awe of the way he can build an argument.
