君子之于禽兽也，见其生，不忍见其死，闻其声，不忍食其肉，是以君子远包厨也。
When you've seen how birds and animals live, you cannot bear to see them killed; when you've heard how birds chirp and animals cry, you cannot bear to eat their meat. Therefore, a man of honor has his kitchen placed out of sight and hearing (or keeps away from his kitchen).
