In the Economist this week:
People have, pace vegetarians, evolved to love meat, which contains many necessary nutrients, and especially protein, in higher concentrations than plants do
I’m used to pace meaning “the speed at which one is moving.” Is there another meaning to this word that makes sense in this context, other than perhaps “Slow down, vegetarians! Don’t be too hasty to rip into us”
It’s Latin for peace. In this context, the writer is indicating that s/he does not want to start an argument with vegetarians.
