It is not only species of animals that die out. But whole species of feelings.

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 animals 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.
