Something having been done just about everywhere just about always is no kind of justification for doing it now.
Jonathan Safran FoerPerhaps in the back of our minds we already understand, without all the science I've discussed, that something terribly wrong is happening. Our sustenance now comes from misery. We know that if someone offers to show us a film on how our meat is produced, it will be a horror film. We perhaps know more than we care to admit, keeping it down in the dark places of our memory-- disavowed. When we eat factory-farmed meat we live, literally, on tortured flesh. Increasingly, that tortured flesh is becoming our own.
Jonathan Safran FoerThe disgraced Usurer Yankel D took the baby girl home that evening... He made a bed of crumpled newspaper in a deep baking pan and gently tucked it in the oven, so that she wouldn't be disturbed by the noise of the small falls outside... When he pulled her out to feed her or just hold her, her body was tattooed with the newsprint... Sometimes he would rock her to sleep in his arms, and read her left to right, and know everything he needed to know about the world. If it wasn't written on her, it wasn't important to him.
