I don't know if it's a hundred years, but it seems to me if history continues-that's not at all obvious, that it will-but if society continues to develop without catastrophe on something like the course that you can sort of see over time, I wouldn't be in the least surprised if it moves toward vegetarianism and protection of animal rights. In fact, what we've seen over the years-and it's hard to be optimistic in the twentieth century, which is one of the worst centuries in human history in terms of atrocities and terror and so on-but still, over the years, including the twentieth century, there is a widening of the moral realm, bringing in broader and broader domains of individuals who are regarded as moral agents.
