Dialogue: 0,0:00:05.00,0:00:07.00,Default,,0000,0000,0000,,And so I've always been very fond of this painter Dialogue: 0,0:00:07.00,0:00:10.00,Default,,0000,0000,0000,,who lived and worked in the 15th century. Dialogue: 0,0:00:10.00,0:00:12.00,Default,,0000,0000,0000,,And what is interesting about him in relation to morality Dialogue: 0,0:00:12.00,0:00:15.00,Default,,0000,0000,0000,,is that he lived at a time where religion's influence was waning, Dialogue: 0,0:00:15.00,0:00:17.00,Default,,0000,0000,0000,,and he was sort of wondering, I think, Dialogue: 0,0:00:17.00,0:00:19.00,Default,,0000,0000,0000,,what would happen with society Dialogue: 0,0:00:19.00,0:00:22.00,Default,,0000,0000,0000,,if there was no religion or if there was less religion. Dialogue: 0,0:00:22.00,0:00:25.00,Default,,0000,0000,0000,,And so he painted this famous painting, "The Garden of Earthly Delights," Dialogue: 0,0:00:25.00,0:00:27.00,Default,,0000,0000,0000,,which some have interpreted Dialogue: 0,0:00:27.00,0:00:29.00,Default,,0000,0000,0000,,as being humanity before the Fall, Dialogue: 0,0:00:29.00,0:00:32.00,Default,,0000,0000,0000,,or being humanity without any Fall at all. Dialogue: 0,0:00:32.00,0:00:34.00,Default,,0000,0000,0000,,And so it makes you wonder, Dialogue: 0,0:00:34.00,0:00:37.00,Default,,0000,0000,0000,,what would happen if we hadn't tasted the fruit of knowledge, so to speak, Dialogue: 0,0:00:37.00,0:00:40.00,Default,,0000,0000,0000,,and what kind of morality would we have? Dialogue: 0,0:00:40.00,0:00:42.00,Default,,0000,0000,0000,,Much later, as a student, Dialogue: 0,0:00:42.00,0:00:44.00,Default,,0000,0000,0000,,I went to a very different garden, Dialogue: 0,0:00:44.00,0:00:47.00,Default,,0000,0000,0000,,a zoological garden in Arnhem Dialogue: 0,0:00:47.00,0:00:49.00,Default,,0000,0000,0000,,where we keep chimpanzees.

Dialogue: 0,0:00:59.00,0:01:02.00,Default,,0000,0000,0000,,And at that time the focus in a lot of animal research Dialogue: 0,0:01:02.00,0:01:04.00,Default,,0000,0000,0000,,was on aggression and competition. Dialogue: 0,0:01:04.00,0:01:06.00,Default,,0000,0000,0000,,I painted a whole picture of the animal kingdom, Dialogue: 0,0:01:06.00,0:01:08.00,Default,,0000,0000,0000,,and humanity included, Dialogue: 0,0:01:08.00,0:01:10.00,Default,,0000,0000,0000,,was that deep down we are competitors, Dialogue: 0,0:01:10.00,0:01:12.00,Default,,0000,0000,0000,,we are aggressive, Dialogue: 0,0:01:12.00,0:01:15.00,Default,,0000,0000,0000,,we're all out for our own profit basically. Dialogue: 0,0:01:15.00,0:01:17.00,Default,,0000,0000,0000,,This is the launch of my book. Dialogue: 0,0:01:17.00,0:01:19.00,Default,,0000,0000,0000,,I'm not sure how well the chimpanzees read it, Dialogue: 0,0:01:19.00,0:01:22.00,Default,,0000,0000,0000,,but they surely seemed interested in the book. Dialogue: 0,0:01:24.00,0:01:26.00,Default,,0000,0000,0000,,Now in the process Dialogue: 0,0:01:26.00,0:01:28.00,Default,,0000,0000,0000,,of doing all this work on power and dominance Dialogue: 0,0:01:28.00,0:01:30.00,Default,,0000,0000,0000,,and aggression and so on, Dialogue: 0,0:01:30.00,0:01:33.00,Default,,0000,0000,0000,,I discovered that chimpanzees reconcile after fights. Dialogue: 0,0:01:33.00,0:01:36.00,Default,,0000,0000,0000,,And so what you see here is two males who have had a fight. Dialogue: 0,0:01:36.00,0:01:39.00,Default,,0000,0000,0000,,They ended up in a tree, and one of them holds out a hand to the other. Dialogue: 0,0:01:39.00,0:01:42.00,Default,,0000,0000,0000,,And about a second after I took the picture, they came together in the fork of the tree Dialogue: 0,0:01:42.00,0:01:44.00,Default,,0000,0000,0000,,and they kissed and embraced each other. Dialogue: 0,0:01:44.00,0:01:46.00,Default,,0000,0000,0000,,Now this is very interesting Dialogue: 0,0:01:46.00,0:01:49.00,Default,,0000,0000,0000,,because at the time everything was about competition and aggression, Dialogue: 0,0:01:49.00,0:01:51.00,Default,,0000,0000,0000,,and so it wouldn't make any sense. Dialogue: 0,0:01:51.00,0:01:53.00,Default,,0000,0000,0000,,The only thing that matters is that you win or that you lose. Dialogue: 0,0:01:53.00,0:01:55.00,Default,,0000,0000,0000,,But why would you reconcile after a fight? Dialogue: 0,0:01:55.00,0:01:57.00,Default,,0000,0000,0000,,That doesn't make any sense. Dialogue: 0,0:01:57.00,0:02:00.00,Default,,0000,0000,0000,,This is the way bonobos do it. Bonobos do everything with sex. Dialogue: 0,0:02:00.00,0:02:02.00,Default,,0000,0000,0000,,And so they also reconcile with sex. Dialogue: 0,0:02:02.00,0:02:04.00,Default,,0000,0000,0000,,But the principle is exactly the same. Dialogue: 0,0:02:04.00,0:02:06.00,Default,,0000,0000,0000,,The principle is that you have Dialogue: 0,0:02:06.00,0:02:08.00,Default,,0000,0000,0000,,a valuable relationship Dialogue: 0,0:02:08.00,0:02:10.00,Default,,0000,0000,0000,,that is damaged by conflict, Dialogue: 0,0:02:10.00,0:02:12.00,Default,,0000,0000,0000,,so you need to do something about it. Dialogue: 0,0:02:12.00,0:02:14.00,Default,,0000,0000,0000,,So my whole picture of the animal kingdom, Dialogue: 0,0:02:14.00,0:02:16.00,Default,,0000,0000,0000,,and including humans also, Dialogue: 0,0:02:16.00,0:02:18.00,Default,,0000,0000,0000,,started to change at that time. Dialogue: 0,0:02:18.00,0:02:20.00,Default,,0000,0000,0000,,So we have this image Dialogue: 0,0:02:20.00,0:02:22.00,Default,,0000,0000,0000,,in political science, economics, the humanities, Dialogue: 0,0:02:22.00,0:02:24.00,Default,,0000,0000,0000,,philosophy for that matter, Dialogue: 0,0:02:24.00,0:02:26.00,Default,,0000,0000,0000,,that man is a wolf to man. Dialogue: 0,0:02:26.00,0:02:29.00,Default,,0000,0000,0000,,And so deep down our nature's actually nasty. Dialogue: 0,0:02:29.00,0:02:32.00,Default,,0000,0000,0000,,I think it's a very unfair image for the wolf. Dialogue: 0,0:02:32.00,0:02:34.00,Default,,0000,0000,0000,,The wolf is, after all, Dialogue: 0,0:02:34.00,0:02:36.00,Default,,0000,0000,0000,,a very cooperative animal. Dialogue: 0,0:02:36.00,0:02:38.00,Default,,0000,0000,0000,,And that's why many of you have a dog at home, Dialogue: 0,0:02:38.00,0:02:40.00,Default,,0000,0000,0000,,which has all these characteristics also. Dialogue: 0,0:02:40.00,0:02:42.00,Default,,0000,0000,0000,,And it's really unfair to humanity, Dialogue: 0,0:02:42.00,0:02:46.00,Default,,0000,0000,0000,,because humanity is actually much more cooperative and empathic Dialogue: 0,0:02:46.00,0:02:48.00,Default,,0000,0000,0000,,than given credit for. Dialogue: 0,0:02:48.00,0:02:50.00,Default,,0000,0000,0000,,So I started getting interested in those issues Dialogue: 0,0:02:50.00,0:02:52.00,Default,,0000,0000,0000,,and studying that in other animals. Dialogue: 0,0:02:52.00,0:02:54.00,Default,,0000,0000,0000,,So these are the pillars of morality. Dialogue: 0,0:02:54.00,0:02:58.00,Default,,0000,0000,0000,,If you ask anyone, "What is morality based on?" Dialogue: 0,0:02:58.00,0:03:00.00,Default,,0000,0000,0000,,these are the two factors that always come out. Dialogue: 0,0:03:00.00,0:03:02.00,Default,,0000,0000,0000,,One is reciprocity, Dialogue: 0,0:03:02.00,0:03:05.00,Default,,0000,0000,0000,,and associated with it is a sense of justice and a sense of fairness. Dialogue: 0,0:03:05.00,0:03:07.00,Default,,0000,0000,0000,,And the other one is empathy and compassion. Dialogue: 0,0:03:07.00,0:03:10.00,Default,,0000,0000,0000,,And human morality is more than this, Dialogue: 0,0:03:10.00,0:03:12.00,Default,,0000,0000,0000,,but if you would remove these two pillars, Dialogue: 0,0:03:12.00,0:03:14.00,Default,,0000,0000,0000,,there would be not much remaining I think. Dialogue: 0,0:03:14.00,0:03:16.00,Default,,0000,0000,0000,,And so they're absolutely essential. Dialogue: 0,0:03:16.00,0:03:18.00,Default,,0000,0000,0000,,So let me give you a few examples here. Dialogue: 0,0:03:18.00,0:03:20.00,Default,,0000,0000,0000,,This is a very old video \Nfrom the Yerkes Primate Center Dialogue: 0,0:03:20.00,0:03:23.00,Default,,0000,0000,0000,,where they train chimpanzees to cooperate. Dialogue: 0,0:03:23.00,0:03:26.00,Default,,0000,0000,0000,,["1937"] So this is already\Nabout a hundred years ago Dialogue: 0,0:03:26.00,0:03:29.00,Default,,0000,0000,0000,,that we were doing experiments on cooperation. Dialogue: 0,0:03:29.00,0:03:32.00,Default,,0000,0000,0000,,What you have here is two young chimpanzees who have a box, Dialogue: 0,0:03:32.00,0:03:35.00,Default,,0000,0000,0000,,and the box is too heavy for one chimp to pull in. Dialogue: 0,0:03:35.00,0:03:37.00,Default,,0000,0000,0000,,And of course, there's food on the box. Dialogue: 0,0:03:37.00,0:03:39.00,Default,,0000,0000,0000,,Otherwise they wouldn't be pulling so hard. Dialogue: 0,0:03:39.00,0:03:41.00,Default,,0000,0000,0000,,And so they're bringing in the box. Dialogue: 0,0:03:41.00,0:03:43.00,Default,,0000,0000,0000,,And you can see that they're synchronized. Dialogue: 0,0:03:43.00,0:03:46.00,Default,,0000,0000,0000,,You can see that they work together, they pull at the same moment. Dialogue: 0,0:03:46.00,0:03:49.00,Default,,0000,0000,0000,,It's already a big advance over many other animals Dialogue: 0,0:03:49.00,0:03:51.00,Default,,0000,0000,0000,,who wouldn't be able to do that. Dialogue: 0,0:03:51.00,0:03:53.00,Default,,0000,0000,0000,,And now you're going to get a more interesting picture, Dialogue: 0,0:03:53.00,0:03:56.00,Default,,0000,0000,0000,,because now one of the two chimps has been fed. Dialogue: 0,0:03:56.00,0:03:58.00,Default,,0000,0000,0000,,So one of the two is not really interested Dialogue: 0,0:03:58.00,0:04:01.00,Default,,0000,0000,0000,,in the task anymore. Dialogue: 0,0:04:01.00,0:04:04.00,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:04:08.00,0:04:13.00,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:04:19.00,0:04:22.73,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:04:23.38,0:04:28.25,Default,,0000,0000,0000,,[" -- and sometimes appears to convey\Nits wishes and meanings by gestures."] Dialogue: 0,0:04:35.76,0:04:38.17,Default,,0000,0000,0000,,Now look at what happens \Nat the very end of this. Dialogue: 0,0:04:41.00,0:04:43.00,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:04:52.00,0:04:54.00,Default,,0000,0000,0000,,He takes basically everything. Dialogue: 0,0:04:54.00,0:04:56.84,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:04:56.84,0:04:59.00,Default,,0000,0000,0000,,So there are two interesting\Nparts about this. Dialogue: 0,0:04:59.00,0:05:01.00,Default,,0000,0000,0000,,One is that the chimp on the right Dialogue: 0,0:05:01.00,0:05:03.00,Default,,0000,0000,0000,,has a full understanding he needs the partner -- Dialogue: 0,0:05:03.00,0:05:05.00,Default,,0000,0000,0000,,so a full understanding of the need for cooperation. Dialogue: 0,0:05:05.00,0:05:08.00,Default,,0000,0000,0000,,The second one is that the partner is willing to work Dialogue: 0,0:05:08.00,0:05:10.00,Default,,0000,0000,0000,,even though he's not interested in the food. Dialogue: 0,0:05:10.00,0:05:13.00,Default,,0000,0000,0000,,Why would that be? Well that probably has to do with reciprocity. Dialogue: 0,0:05:13.00,0:05:15.00,Default,,0000,0000,0000,,There's actually a lot of evidence in primates and other animals Dialogue: 0,0:05:15.00,0:05:17.00,Default,,0000,0000,0000,,that they return favors. Dialogue: 0,0:05:17.00,0:05:19.00,Default,,0000,0000,0000,,So he will get a return favor Dialogue: 0,0:05:19.00,0:05:21.00,Default,,0000,0000,0000,,at some point in the future. Dialogue: 0,0:05:21.00,0:05:23.00,Default,,0000,0000,0000,,And so that's how this all operates. Dialogue: 0,0:05:23.00,0:05:25.00,Default,,0000,0000,0000,,We do the same task with elephants. Dialogue: 0,0:05:25.00,0:05:28.00,Default,,0000,0000,0000,,Now with elephants, it's very dangerous to work with elephants. Dialogue: 0,0:05:28.00,0:05:30.00,Default,,0000,0000,0000,,Another problem with elephants Dialogue: 0,0:05:30.00,0:05:32.00,Default,,0000,0000,0000,,is that you cannot make an apparatus Dialogue: 0,0:05:32.00,0:05:34.00,Default,,0000,0000,0000,,that is too heavy for a single elephant. Dialogue: 0,0:05:34.00,0:05:36.00,Default,,0000,0000,0000,,Now you can probably make it, Dialogue: 0,0:05:36.00,0:05:38.00,Default,,0000,0000,0000,,but it's going to be a pretty flimsy apparatus I think. Dialogue: 0,0:05:38.00,0:05:40.00,Default,,0000,0000,0000,,And so what we did in that case -- Dialogue: 0,0:05:40.00,0:05:43.00,Default,,0000,0000,0000,,we do these studies in Thailand for Josh Plotnik -- Dialogue: 0,0:05:43.00,0:05:46.00,Default,,0000,0000,0000,,is we have an apparatus around which there is a rope, a single rope. Dialogue: 0,0:05:46.00,0:05:48.00,Default,,0000,0000,0000,,And if you pull on this side of the rope, Dialogue: 0,0:05:48.00,0:05:50.00,Default,,0000,0000,0000,,the rope disappears on the other side. Dialogue: 0,0:05:50.00,0:05:53.00,Default,,0000,0000,0000,,So two elephants need to pick it up at exactly the same time and pull. Dialogue: 0,0:05:53.00,0:05:55.00,Default,,0000,0000,0000,,Otherwise nothing is going to happen Dialogue: 0,0:05:55.00,0:05:57.00,Default,,0000,0000,0000,,and the rope disappears. Dialogue: 0,0:05:57.00,0:05:59.00,Default,,0000,0000,0000,,And the first tape you're going to see Dialogue: 0,0:05:59.00,0:06:01.00,Default,,0000,0000,0000,,is two elephants who are released together Dialogue: 0,0:06:01.00,0:06:03.00,Default,,0000,0000,0000,,arrive at the apparatus. Dialogue: 0,0:06:03.00,0:06:06.00,Default,,0000,0000,0000,,The apparatus is on the left with food on it. Dialogue: 0,0:06:06.00,0:06:09.00,Default,,0000,0000,0000,,And so they come together, they arrive together, Dialogue: 0,0:06:09.00,0:06:11.00,Default,,0000,0000,0000,,they pick it up together and they pull together. Dialogue: 0,0:06:11.00,0:06:14.00,Default,,0000,0000,0000,,So it's actually fairly simple for them. Dialogue: 0,0:06:15.00,0:06:17.00,Default,,0000,0000,0000,,There they are. Dialogue: 0,0:06:24.00,0:06:26.00,Default,,0000,0000,0000,,And so that's how they bring it in. Dialogue: 0,0:06:26.00,0:06:28.00,Default,,0000,0000,0000,,But now we're going to make it more difficult.

Dialogue: 0,0:07:51.00,0:07:53.00,Default,,0000,0000,0000,,And empathy has sort of two qualities. Dialogue: 0,0:07:53.00,0:07:56.00,Default,,0000,0000,0000,,One is the understanding part of it. This is just a regular definition: Dialogue: 0,0:07:56.00,0:07:58.00,Default,,0000,0000,0000,,the ability to understand and share the feelings of another. Dialogue: 0,0:07:58.00,0:08:00.00,Default,,0000,0000,0000,,And the emotional part. Dialogue: 0,0:08:00.00,0:08:02.00,Default,,0000,0000,0000,,And so empathy has basically two channels. Dialogue: 0,0:08:02.00,0:08:04.00,Default,,0000,0000,0000,,One is the body channel.

Dialogue: 0,0:08:11.00,0:08:14.00,Default,,0000,0000,0000,,And that's sort of the body channel of emotional empathy, Dialogue: 0,0:08:14.00,0:08:16.00,Default,,0000,0000,0000,,which many animals have. Dialogue: 0,0:08:16.00,0:08:18.00,Default,,0000,0000,0000,,Your average dog has that also. Dialogue: 0,0:08:18.00,0:08:20.00,Default,,0000,0000,0000,,That's actually why people keep mammals in the home Dialogue: 0,0:08:20.00,0:08:22.00,Default,,0000,0000,0000,,and not turtles or snakes or something like that Dialogue: 0,0:08:22.00,0:08:24.00,Default,,0000,0000,0000,,who don't have that kind of empathy. Dialogue: 0,0:08:24.00,0:08:26.00,Default,,0000,0000,0000,,And then there's a cognitive channel, Dialogue: 0,0:08:26.00,0:08:28.00,Default,,0000,0000,0000,,which is more that you can take the perspective of somebody else. Dialogue: 0,0:08:28.00,0:08:30.00,Default,,0000,0000,0000,,And that's more limited. Dialogue: 0,0:08:30.00,0:08:32.00,Default,,0000,0000,0000,,There's few animals -- I think elephants and apes can do that kind of thing -- Dialogue: 0,0:08:32.00,0:08:35.00,Default,,0000,0000,0000,,but there are very few animals who can do that. Dialogue: 0,0:08:35.00,0:08:37.00,Default,,0000,0000,0000,,So synchronization, Dialogue: 0,0:08:37.00,0:08:39.00,Default,,0000,0000,0000,,which is part of that whole empathy mechanism Dialogue: 0,0:08:39.00,0:08:41.00,Default,,0000,0000,0000,,is a very old one in the animal kingdom. Dialogue: 0,0:08:41.00,0:08:43.00,Default,,0000,0000,0000,,And in humans, of course, we can study that Dialogue: 0,0:08:43.00,0:08:45.00,Default,,0000,0000,0000,,with yawn contagion.

Dialogue: 0,0:08:49.00,0:08:51.00,Default,,0000,0000,0000,,It activates the same areas in the brain. Dialogue: 0,0:08:51.00,0:08:53.00,Default,,0000,0000,0000,,Also, we know that people who have a lot of yawn contagion Dialogue: 0,0:08:53.00,0:08:55.00,Default,,0000,0000,0000,,are highly empathic. Dialogue: 0,0:08:55.00,0:08:57.00,Default,,0000,0000,0000,,People who have problems with empathy, such as autistic children, Dialogue: 0,0:08:57.00,0:08:59.00,Default,,0000,0000,0000,,they don't have yawn contagion. Dialogue: 0,0:08:59.00,0:09:01.00,Default,,0000,0000,0000,,So it is connected. Dialogue: 0,0:09:01.00,0:09:04.00,Default,,0000,0000,0000,,And we study that in our chimpanzees by presenting them with an animated head.

Dialogue: 0,0:09:32.00,0:09:35.00,Default,,0000,0000,0000,,And that's related to that whole body channel of synchronization Dialogue: 0,0:09:35.00,0:09:37.00,Default,,0000,0000,0000,,that underlies empathy Dialogue: 0,0:09:37.00,0:09:40.00,Default,,0000,0000,0000,,and that is universal in the mammals basically. Dialogue: 0,0:09:40.00,0:09:43.00,Default,,0000,0000,0000,,Now we also study more complex expressions. This is consolation.

Dialogue: 0,0:09:58.00,0:10:01.00,Default,,0000,0000,0000,,Actually the way to study empathy in human children Dialogue: 0,0:10:01.00,0:10:03.00,Default,,0000,0000,0000,,is to instruct a family member to act distressed, Dialogue: 0,0:10:03.00,0:10:05.00,Default,,0000,0000,0000,,and then they see what young children do. Dialogue: 0,0:10:05.00,0:10:07.00,Default,,0000,0000,0000,,And so it is related to empathy, Dialogue: 0,0:10:07.00,0:10:10.00,Default,,0000,0000,0000,,and that's the kind of expressions we look at. Dialogue: 0,0:10:10.00,0:10:13.00,Default,,0000,0000,0000,,We also recently published an experiment you may have heard about.

Dialogue: 0,0:10:20.00,0:10:22.00,Default,,0000,0000,0000,,And for decades it had been assumed Dialogue: 0,0:10:22.00,0:10:24.00,Default,,0000,0000,0000,,that only humans can do that, Dialogue: 0,0:10:24.00,0:10:27.00,Default,,0000,0000,0000,,that only humans worry about the welfare of somebody else. Dialogue: 0,0:10:27.00,0:10:29.00,Default,,0000,0000,0000,,Now we did a very simple experiment. Dialogue: 0,0:10:29.00,0:10:32.00,Default,,0000,0000,0000,,We do that on chimpanzees that live in Lawrenceville, Dialogue: 0,0:10:32.00,0:10:34.00,Default,,0000,0000,0000,,in the field station of Yerkes. Dialogue: 0,0:10:34.00,0:10:36.00,Default,,0000,0000,0000,,And so that's how they live. Dialogue: 0,0:10:36.00,0:10:39.00,Default,,0000,0000,0000,,And we call them into a room and do experiments with them. Dialogue: 0,0:10:39.00,0:10:41.00,Default,,0000,0000,0000,,In this case, we put two chimpanzees side-by-side. Dialogue: 0,0:10:41.00,0:10:44.00,Default,,0000,0000,0000,,and one has a bucket full of tokens, and the tokens have different meanings.

Dialogue: 0,0:10:49.00,0:10:52.00,Default,,0000,0000,0000,,So this is a study we did with Vicky Horner. Dialogue: 0,0:10:53.00,0:10:55.00,Default,,0000,0000,0000,,And here you have the two color tokens. Dialogue: 0,0:10:55.00,0:10:57.00,Default,,0000,0000,0000,,So they have a whole bucket full of them. Dialogue: 0,0:10:57.00,0:11:00.00,Default,,0000,0000,0000,,And they have to pick one of the two colors. Dialogue: 0,0:11:00.00,0:11:03.00,Default,,0000,0000,0000,,You will see how that goes. Dialogue: 0,0:11:03.00,0:11:06.00,Default,,0000,0000,0000,,So if this chimp makes the selfish choice, Dialogue: 0,0:11:06.00,0:11:09.00,Default,,0000,0000,0000,,which is the red token in this case, Dialogue: 0,0:11:09.00,0:11:11.00,Default,,0000,0000,0000,,he needs to give it to us. Dialogue: 0,0:11:11.00,0:11:14.00,Default,,0000,0000,0000,,So we pick it up, we put it on a table where there's two food rewards, Dialogue: 0,0:11:14.00,0:11:17.00,Default,,0000,0000,0000,,but in this case only the one on the right gets food. Dialogue: 0,0:11:17.00,0:11:19.00,Default,,0000,0000,0000,,The one on the left walks away because she knows already.

Dialogue: 0,0:11:24.00,0:11:27.00,Default,,0000,0000,0000,,So the one who makes the choices -- that's the interesting part here -- Dialogue: 0,0:11:27.00,0:11:29.00,Default,,0000,0000,0000,,for the one who makes the choices, Dialogue: 0,0:11:29.00,0:11:31.00,Default,,0000,0000,0000,,it doesn't really matter. Dialogue: 0,0:11:31.00,0:11:34.00,Default,,0000,0000,0000,,So she gives us now a pro-social token and both chimps get fed. Dialogue: 0,0:11:34.00,0:11:37.00,Default,,0000,0000,0000,,So the one who makes the choices always gets a reward. Dialogue: 0,0:11:37.00,0:11:39.00,Default,,0000,0000,0000,,So it doesn't matter whatsoever. Dialogue: 0,0:11:39.00,0:11:41.00,Default,,0000,0000,0000,,And she should actually be choosing blindly. Dialogue: 0,0:11:41.00,0:11:43.00,Default,,0000,0000,0000,,But what we find Dialogue: 0,0:11:43.00,0:11:45.00,Default,,0000,0000,0000,,is that they prefer the pro-social token. Dialogue: 0,0:11:45.00,0:11:48.00,Default,,0000,0000,0000,,So this is the 50 percent line that's the random expectation. Dialogue: 0,0:11:48.00,0:11:51.00,Default,,0000,0000,0000,,And especially if the partner draws attention to itself, they choose more.

Dialogue: 0,0:12:00.00,0:12:02.00,Default,,0000,0000,0000,,It's as if they're saying, Dialogue: 0,0:12:02.00,0:12:04.00,Default,,0000,0000,0000,,"If you're not behaving, I'm not going to be pro-social today." Dialogue: 0,0:12:04.00,0:12:06.00,Default,,0000,0000,0000,,And this is what happens without a partner, Dialogue: 0,0:12:06.00,0:12:08.00,Default,,0000,0000,0000,,when there's no partner sitting there. Dialogue: 0,0:12:08.00,0:12:10.00,Default,,0000,0000,0000,,And so we found that the chimpanzees do care Dialogue: 0,0:12:10.00,0:12:12.00,Default,,0000,0000,0000,,about the well-being of somebody else -- Dialogue: 0,0:12:12.00,0:12:15.00,Default,,0000,0000,0000,,especially, these are other members of their own group.

Dialogue: 0,0:14:57.00,0:14:59.00,Default,,0000,0000,0000,,This study became very famous Dialogue: 0,0:14:59.00,0:15:01.00,Default,,0000,0000,0000,,and we got a lot of comments, Dialogue: 0,0:15:01.00,0:15:03.00,Default,,0000,0000,0000,,especially anthropologists, economists, Dialogue: 0,0:15:03.00,0:15:05.00,Default,,0000,0000,0000,,philosophers. Dialogue: 0,0:15:05.00,0:15:07.00,Default,,0000,0000,0000,,They didn't like this at all. Dialogue: 0,0:15:07.00,0:15:10.00,Default,,0000,0000,0000,,Because they had decided in their minds, I believe, Dialogue: 0,0:15:10.00,0:15:12.00,Default,,0000,0000,0000,,that fairness is a very complex issue Dialogue: 0,0:15:12.00,0:15:14.00,Default,,0000,0000,0000,,and that animals cannot have it. Dialogue: 0,0:15:14.00,0:15:16.00,Default,,0000,0000,0000,,And so one philosopher even wrote us Dialogue: 0,0:15:16.00,0:15:19.00,Default,,0000,0000,0000,,that it was impossible that monkeys had a sense of fairness Dialogue: 0,0:15:19.00,0:15:22.00,Default,,0000,0000,0000,,because fairness was invented during the French Revolution. Dialogue: 0,0:15:22.00,0:15:24.00,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:15:24.00,0:15:27.00,Default,,0000,0000,0000,,Now another one wrote a whole chapter Dialogue: 0,0:15:27.00,0:15:31.00,Default,,0000,0000,0000,,saying that he would believe it had something to do with fairness Dialogue: 0,0:15:31.00,0:15:33.00,Default,,0000,0000,0000,,if the one who got grapes would refuse the grapes. Dialogue: 0,0:15:33.00,0:15:35.00,Default,,0000,0000,0000,,Now the funny thing is that Sarah Brosnan, Dialogue: 0,0:15:35.00,0:15:37.00,Default,,0000,0000,0000,,who's been doing this with chimpanzees, Dialogue: 0,0:15:37.00,0:15:39.00,Default,,0000,0000,0000,,had a couple of combinations of chimpanzees Dialogue: 0,0:15:39.00,0:15:42.00,Default,,0000,0000,0000,,where, indeed, the one who would get the grape would refuse the grape Dialogue: 0,0:15:42.00,0:15:44.00,Default,,0000,0000,0000,,until the other guy also got a grape. Dialogue: 0,0:15:44.00,0:15:47.00,Default,,0000,0000,0000,,So we're getting very close to the human sense of fairness. Dialogue: 0,0:15:47.00,0:15:51.00,Default,,0000,0000,0000,,And I think philosophers need to rethink their philosophy for awhile. Dialogue: 0,0:15:51.00,0:15:53.00,Default,,0000,0000,0000,,So let me summarize. Dialogue: 0,0:15:53.00,0:15:55.00,Default,,0000,0000,0000,,I believe there's an evolved morality.

Dialogue: 0,0:16:07.00,0:16:10.00,Default,,0000,0000,0000,,And so we work on these particular issues Dialogue: 0,0:16:10.00,0:16:13.00,Default,,0000,0000,0000,,to see if we can create a morality from the bottom up, so to speak, Dialogue: 0,0:16:13.00,0:16:15.00,Default,,0000,0000,0000,,without necessarily God and religion involved, Dialogue: 0,0:16:15.00,0:16:18.00,Default,,0000,0000,0000,,and to see how we can get to an evolved morality.
