Nice poem! I have almost forgotten it! I thought a lot about this one when I first read it. And William Blake asks the just question: one and the same Power caused the appearence of a lamb and of a tiger on the Earth - Is that OK? Of course we all speak about the eco-balance: Too much game is bad for the earth, that is why there should be hunters to hunt the game! But now Tigers are disappearing - hunting people killed almost all of them. They are strong animals, but a bit tricky and not so nobel as lions and cheetahs are. But you - our nice Tiger - are much-much-much-much better than all those nobel animals are! And cleverer, as a matter of fact!
