I spend a lot of time looking at the various primates and cuttlefish thinking very much about what they "think" and whether we could even conceptualize the self-awareness experience they seem to have.

It seems possible that we could eventually gain a better understanding of the intelligences of other species, but at this point most of our consideration of them is a fashioning of mirrors to better examine ourselves. This self-regard was the original purpose of zoos, and it still explains much of their existence.
