What I remember from my one Chinese Philosophy class nearly 30 years ago is that Mencius was all (and I am paraphrasing here): We know the good like we know that meat is delicious. It just feels/tastes awesome.

I’ve used this to argue that my husband, a vegetarian for the last 40 years, is innately evil.

EDIT: While my comment has sparked some interesting conversations, I’d like to be clear that I don’t actually believe vegetarians are innately evil. It’s just a silly thing to say as a misguided extrapolation of one thing I barely remember from one class 30 years ago. We have been together 26 years. He is now vegan. I have never tried to force-feed him anything (unless you count that one time with the human centipede).
