Religion's pretty pervasive in humans. And why it's pervasive in humans is debated a lot. There are indications of things that look like religion in other animals, like chimps doing rain dances, and that sort of thing. Actually, I say that, but there's that and not much else.
Hal WhiteheadConversation with animals could happen, but I think it would be easier for it to happen with creatures we share a bit more with - those that have been bred to interact with us, like dogs or horses, or ones to whom we have a natural evolutionary link, like chimps and other nonhuman apes. I mean, we do communicate with dolphins and whales, but we're not trying to get to the depths of their understandings. I feel that with animals as different from us as the whales and dolphins, it's likely to work better with us just watching them and trying to figure them out.
Hal WhiteheadCulture is not usually one of the criterion for personhood, but it has been argued that culture is sort of a medium for a lot of these criteria, such as empathy, and so on.
Hal WhiteheadIt's kind of ironic that when you look at the evidence of intelligence and so on, a lot of it is anecdotal. A lot of it is, "Well, we saw this dolphin do this extraordinary thing," or, "We screwed up with our apparatus, and then the dolphins did this." And so it seems to me that the more we can actually watch them doing their thing, the better chance we'll have of making some sense of them.
