When so much mistreatment of animals continues, when the cries of thirsty beasts from our railway cars die out unheard, when so much brutality prevails in our slaughterhouses, when animals meet a painful death in our kitchens, when animals suffer incredibly from merciless men and are turned over to the cruel play of children, WE ALL BEAR THE GUILT FOR IT. We are afraid of shocking people if we let it be noticed how much we are moved by the suffering man brings to animals. We think that others may have become more 'rational' than we, and may accept as customary and as a matter of course the things we have gotten excited about. Once in a while, however, a word suddenly slips out which shows that even they have not yet become reconciled to this suffering. Now they come very close to us though they were formerly strangers. The masks with which we were deceiving each other fall off. Now we learn from each other that no one is able to escape the grip of the cruelty that flourishes ceaselessly around us.'

But in the world of books are volumes that have seen this happen again and again and yet live on. Still young, still as fresh as the day they were written, still telling men's hearts, of the hearts of men centuries dead.

You young people can lend your bodies now, play with them, give them as we could not. But remember that you have paid a price: that of a world rich in mystery and delicate emotion. It is not only species of animal that die out. But whole species of feelings. And if you are wise, you will never pity the past for what it did not know. But pity yourself for what it did.
