It’s a rich meal, but this is the morsel I liked best:

“Ordering done, I ask Singer if he is surprised or disappointed at how much has changed in the 30 years since he published his groundbreaking Animal Liberation.

” ‘Both, I guess,’ says Singer. ‘When we started people told us you’ll never change this. There have been significant changes, particularly in Europe.’ He pauses. ‘On the other hand, when I was writing Animal Liberation it seemed to me that the arguments were so clear that what we were doing was wrong and indefensible that I hoped people would just read it and say that has got to stop. And it hasn’t.’”
