"The very beginning of Genesis tells us that God created man in order to give him dominion over fish and fowl and all creatures. Of course, Genesis was written by a man, not a horse. There is no certainty that God actually did grant man dominion over other creatures. What seems more likely, in fact, is that man invented God to sanctify the dominion that he had usurped himself over the cow and the horse. Yes, the right to kill a deer or a cow is the only thing that all of mankind can agree upon, even during the bloodiest of wars.
The reason we take that right for granted is that we stand at the top of the hierarchy. But let a third party enter the game– a visitor from another planet, for example, someone to whom God says, “Thou shalt have dominion over the creatures of all other stars”– and all at once taking Genesis for granted becomes problematical. Perhaps a man hitched to the cart of a Martian or roasted on the spit by inhabitants of the Milky Way will recall the veal cutlet he used to slice on his dinner plate and apologize (belatedly!) to the cow."
