“The most striking quality that humans and animals have in common is the capacity to experience suffering. Why do we still blind ourselves, now at the beginning of the twenty-first century, to the immeasurable suffering that we inflict on animals, knowing that a great part of the pain that we cause them is neither necessary nor unavoidable? Certainly we should know that there is no moral justification for inflicting needless pain and death on any being.”

Context: There slowly grew up in me an unshakable conviction that we have no right to inflict suffering and death on another living creature unless there is some unavoidable necessity for it, and that we ought all of us to feel what a horrible thing it is to cause suffering and death out of mere thoughtlessness. And this conviction has influenced me only more and more strongly with time. I have grown more and more certain that at the bottom of our heart we all think this, and that we fail to acknowledge it because we are afraid of being laughed at by other people as sentimentalists, though partly also because we allow our best feelings to get blunted. But I vowed that I would never let my feelings get blunted, and that I would never be afraid of the reproach of sentimentalism.
