Peter Singer: I do want to challenge you, the 
conference is subtitled, Cognitive 
disability: A challenge to moral 
philosophy, and I think it goes in both
directions, actually. Moral philosophy 
is a challenge to how we think 
about people with cognitive disability 
and, to some extent, to how we think 
about questions of moral status. So a 
lot of the issues that I was thinking 
about in listening to previous sessions 
like the one we just had now... a 
lot of the issues, I think, people are 
thinking within a certain sphere...
 we're thinking within a certain sphere, 
and I want to broaden the sphere 
so that we are not just looking at 
people with cognitive disabilities but 
we're looking at how our thoughts about 
moral status altogether relate to 
beings who do not have the cognitive 
abilities that normal humans do have. 
That's really what I want to talk about.
