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.

It’s short. About 50 pages. I don’t agree with everything she says because, despite her interlocutor and friend being homosexual, she makes a few homophobic comments. I chose this book because it’s witty and fun, it raises some fundamental questions about the nature of love, and also it’s a fascinating insight into society at the time.

Frank Henderson Stewart is a very distinguished scholar, now retired, an expert on the ancient Near East, but he thought deeply about honour. He read ancient texts and legal documents because, as you know, honour is a legal concept in German law and you can seek to have your honour protected in various ways – it’s sort of what they have instead of libel. Analysing and thinking deeply about it, he tries to understand how honour developed, and it was he who led me to see the core thought, which is that honour is an entitlement to respect, and that what honour codes do is say how you get to be entitled to respect. I disagree with a lot of what he says – in particular that he wants to give up on honour because it has such negative connotations: I think it needs reform as a concept – but I think it’s a very lovely piece of scholarly analysis.

I often hate-read the Daily Mail. It’s the worst of media and the worst of mankind distilled into one publication and in some ways it feels a moral duty to be familiar with it. Too often we all bolt ourselves into an echo chamber, which I think lacks courage, and can lead to a kind of intellectual conceitedness.
