consciência e moralidade

"I remember talking to some people about space travel, and they were interested in making computer-controled devices that went and sat on planets, and if they were really intelligent then they didn't need to send people. But if they're really intelligent maybe they have to be conscious too - they said, 'Yes, yes, well of course they'll be'; but then if they're conscious, well, you've got to bring them back, you've got a moral responsability to them."

Roger Penrose
