The problem with ID, of course, is that it leaves open the possibility that the intelligence behind nature may have a moral interest in us, having communicated already with humanity in the past, and might try to boss you around in your private affairs.With hypothetical advanced aliens residing at a safely distant address in the hypothetical multiverse, that is - to the relief of folks like Gribbin, Dawkins and the - manifestly not the case.
Since we are not yet fully comfortable with the idea that people from the next village are as human as ourselves, it is presumptuous in the extreme to suppose we could ever look at sociable, tool-making creatures who arose from other evolutionary paths and see not beasts but brothers, not rivals by fellow pilgrims journeying to the shrine of intelligence. Yet that is what I see, or yearn to see. The difference between raman and varelse is not in the creature judged but in the creature judging, and when we declare an alien species to be raman, it does not mean that they have passed a threshold of moral maturity. It means that we have.
