Here is the full debate transcript from Stand to Reason.

And here’s an excerpt:

GK: Right. Actually, the big question here, Hugh, is whether it’s possible to be good without God. Now I’m not talking about whether it’s possible to be good without a belief in God. I certainly think that’s possible, but be good without God. And the answer to that question hinges entirely on precisely what you mean by good. And so I was going to give an illustration. So a man drags a young girl into the alley, he sexually abuses her, strangles here, and tosses her into the dustbin. Is that act wrong? Now I think everybody listening is going to admit it is wrong. But here is the real question. What do we mean when we say that that act of rape and abuse and murder is wrong? Are we describing the action itself, the object? Are we saying that the object, the rape, the murder, has a quality of being wrong, and therefore, wherever that rape goes, the wrongness follows it, just like your height, 6’ 2”, or whatever it is, is an objective quality of you. Wherever you go, your height follows you in the same way. Does the wrongness follow the rape? Well, if it’s a quality of the rape, if it’s an objective quality of the rape, then it does. And it doesn’t matter what people think about it, or what cultures decides, or what your evolutionary conditioning is. The rape is still wrong. The other alternative is that you’re not talking about the rape. You’re talking about yourself. You’re talking about your genetic conditioning. You’re talking about your culture’s decision about that kind of thing. And if that’s the case, then the truth of the wrongness of the rape is simply in the individual or the subject. And this is why philosophers distinguish between ethical objectivism and ethical subjectivism. Now there’s lots of different subjectivisms in ethics. But simply put, if you’re an ethical subjectivist, you’re a relativist. And actual ethics don’t exist. Ethics are an illusion. If you conclude that ethics are an illusion, there’s lots of different ways to explain it. Michael’s written a really great book, I think, called The Science Of Good And Evil. I’ve read most of it, and it’s well written, and it’s very compelling. But it’s a description about how the illusion of ethics has taken place. If you want to go that route, you’re welcome to go that route. But what you can’t do is you can’t then talk about morality as if it’s objective when your explanations are subjective. So this is a problem that I think all atheists, including Michael, have to solve. Are ethics objective or relative? And if they’re relative, then how can we make moral judgments that are meaningful on other people?

HH: Michael Shermer?

MS: Wow, let’s just get right into it. Well, I don’t think it’s quite so black and white. That is to say I think there are provisional moral truths that exist whether there’s a God or not. In other words, it’s wrong, morally, absolutely morally wrong to rape and murder. And that would be true whether there was a God or not. In other words, if…is God saying that it’s wrong because it’s really wrong, and He’s instructing us in his Holy Scripture that it’s wrong? Or is it only wrong because He said so? And if it turned out there wasn’t a God, would that make it okay? And my answer is no, it really is wrong, whether God says it’s wrong or not. That is to say I think it really exists, a real, moral standard like that. Why? Well, because first, you could ask the person who is being affected, we should always ask the moral recipient of the act, how do you feel about being raped or murdered or stolen from or lied to. And the moral actor will tell you, it doesn’t matter whether, if I could use a current example, I haven’t any idea if Tiger Woods and his wife are religious or not. But you can just ask his wife whether it was morally right or wrong, and she’ll tell you. It doesn’t matter whether there’s a God or not. It’s wrong. And so that’s the first principle. Just ask. Ask the moral recipient of whether it’s right or wrong. But I think Greg’s after something deeper, that is to say is there something even deeper still behind the moral actor’s feelings about how they’re treated. And the answer is yes, I think so. We’re a social species. We don’t live in isolation. We live as members of a group. And as such, there’s no possible way our group could survive, be cohesive, be a unit of any kind of solidarity against other groups, or against a harsh environment. If there were too much violations of social norms, that is if there were constant lying and cheating and raping and murdering, there’s no way a social group could hang together. And as such, as we all know, we’re very tribal. We’re tribal against other groups, but within our groups, we’re very pro-social, altruistic, cooperative. We have a good and evil in our nature. So to this extent, I find myself interesting often in agreement with my conservative friends on most of the things they consider morally, moral truths. That is, we share the same moral values, even though I come at it from a different perspective.

HH: Greg?

GK: Yeah, I’m actually not after something deeper here, Michael. At least to start out the discussion, I’m trying to be as simple and clear and precise as possible, because it’s very easy to weave together a bunch of things that sound persuasive, but turn out to be different things. Like for example, Darwinian evolution, which is a materialistic process, and here I mean the blind watchmaker thesis, the neo-Darwinian synthesis, natural selection working on mutations, and a kind of a cultural evolution that Michael has just referred to as we work together as a group to survive as a group. Those are two entirely different things. One is materialistic, Darwinian, the other one is intelligent design, quite frankly, where the group gets together and makes some determinations to encourage some behavior and discourage others. What I’m trying to do is to be able to answer the question that came up initially, is God necessary for morality, which Michael denies. It’s to say well, what is it that morality, that we’re trying to describe? It is either objective, and therefore an immaterial obligation that applies to certain behaviors, or it is subjective. The things that Michael described were variously subjective, evolutionary elements, subjective cultural elements, but then he affirmed that we all have good and evil in our nature, or an awareness of that. I agree with that entirely. We all are aware of those things. That’s why even if we don’t believe in God, we can still know morality and follow it. The question is what accounts for real, genuine objective morality?

HH: One minute to the break, Michael Shermer.

MS: I’m not arguing for cultural evolution. I’m actually arguing as part of our, what you described as materialistic, natural selection, Darwinian evolution, that it’s not enough to just pretend or fake being a good group member. You actually have to believe it, feel it, and live it. So what I’m arguing is that natural selected certain moral sentiments, as Adam Smith called them, moral feelings, an actual empathy, Adam Smith talked about, we actually empathize with somebody else, we can put ourselves into their shoes and feel their pain, I’m arguing that’s very real. It’s every bit as real a part of our evolutionary heritage as our eyes and our hands.

– – – –

HH: Michael Shermer, when we went to break, you were saying that evolutionary biology has produced a real morality.

MS: Yeah, I think really, Adam Smith had it right in his very first book, The Theory Of Moral Sentiments, long before Darwin, that we actually have in our biological nature, our human nature, the capacity to feel other people’s pain. He called it empathy, we think of it often either as empathy or sympathy. That is, we really do connect to other people. A lot of good research on this now, brain scans, you can show somebody a little video of somebody they know, or have feelings for, getting pricked with a pin, and the same areas of their brain light up, the pain receptors, as in the person getting the pin prick. In other words, we have an evolved tendency to really be deeply, emotionally connected to our fellow group members. And that’s why I say groups like World Vision, where you want to adopt a child, it doesn’t help to show a picture of 10,000 starving African kids. What does affect us is one child, a picture of one child with a little biography. That’s how you get people to adopt a child to donate. The reason for that is because essentially they’re tricking the brain, our brains into making that stranger an honorary family member, an honorary within group member, which is why I argue that free trade is one of the best ways of defusing normal tribal tensions between people. It makes them honorary friends, honorary members. Well, what’s going on there is we’re tricking the brain into sort of this evolutionary rule of thumb – be nice to people that are like you and that are related to you, and that you know, and that are fellow group members, and don’t do what our natural tendency is, is to be tribal and xenophobic against those other guys. And free trade is one of the best things you can do for that. So I’m arguing that’s actually tapping something deep within us.

HH: Greg Koukl?

GK: Yeah, basically, I agree with Mike completely here. We do have this tendency, and it seems to be universal among humankind. The question is, what is that tendency, actually? And what is the best way to explain it? And I see like a handful of significant problems with using evolution to explain morality. The first one is that evolution is a materialistic process. And here, I’m going back to an original point, and I don’t want people to lose it. There is no way that you can take molecules, and reorganize them in any fashion, over any length of time, and have pop out of the mixture an objective moral principle that’s immaterial, and that applies to human beings. All you’re going to get is a reorganization of the molecules. And what they can produce, and this is what Mike has done in his book, and he mentioned just s few moments ago, they can produce sentiments. They can produce feelings. They can produce behavior. But this leads us to the second problem of using evolution to explain morality, is that morality is more than sentiments, feelings and behavior. Morality entails things like motive and intention. I mean, you could have a guy walk into a garage, walk out with a hose, and is that wrong? Well, it depends. Is it his hose or somebody else’s hose? Did he intend to take the other person’s hose? Is he borrowing the hose? So we can see here are elements that are part of the moral thing that needs to be explained, that are immaterial, and therefore the Darwinian explanation can’t even in principle go there. It can’t do that job. But here’s the worst problem. Regardless of what our sentiments happen to be regarding moral actions, we can feel good or feel bad or whatever, the problem is that morality is prescriptive, not merely descriptive. That is it tells us not just what we did, but what we ought to have done in the past, and what we ought to do in the future. That is not something that any Darwinian mechanism can describe, because nothing about my biology can inveigh upon me to act a certain way for moral reasons in the future. It doesn’t tell me why I should be good tomorrow. This is a huge difference between these two views, the descriptive and the prescriptive. Prescriptive is part of morality, and can’t even, in principle, be explained by an evolutionary materialistic system.

HH: Michael Shermer, I’ll give you a start on that. We have about 45 seconds to the break, so you may want to…we’ll come back after the break and pick up. But what’s your start to that?

MS: Well, the start would be that again, let’s not think of evolution just as nature red and tooth and claw, and it’s nasty, brutish and short, but that in fact, we have this whole other social evolution. And I’m not talking about cultural evolution where we consciously make decisions, but subconsciously, because it’s in part of our nature to actually, seriously, deeply feel for other people and their actions, and the consequences of our actions, so that we actually have a sense of right and wrong that we’re born with, but then culture taps into and tweaks, one way or the other.

– – – –

HH: Michael Shermer, when we went to break, Greg had made the argument that the Darwinian model simply cannot explain immaterial concepts like morality, that there’s just no way you can rearrange the molecules to get there. You’re saying well, yes you can.

MS: Yeah, I think so, because if we think of morality as another suite of emotions that are involved with other people’s behaviors, the consequences of our actions, how we feel about them, how people feel about us when we do these things, that’s as every bit as important a biological part of our nature as anything else we talk about. So let’s take a real simple emotion. When you’re hungry, nobody does any calculations about the caloric input/output ratios of eating an apple versus an ice cream, although now it’s posted on the walls for us to see. But we just feel hungry, and we feel hungry for certain kinds of foods. The feeling of hunger is a proxy for something else. Evolution’s done the calculating for us. You need food, so we’re going to, your hypothalamus is going to secrete these certain chemicals that causes your stomach to rumble and so on. When you’re attracted to somebody else, a member of the opposite sex, nobody does the calculation by, let’s say, a man finds a woman attractive who has a .67 hip to waist ratio, and an hourglass figure, although that is pretty much universal. Nobody walks about with calipers taking measurements of who they’re going to want to date or ask out. You just look around, and you just go wow, I really find this woman attractive. It’s a feeling you have, okay? So those are kind of simple emotions, but sliding up the scale, the moral emotions are really no different. When I lie to somebody, I’ve violated a social norm, and they respond in a very angry, hostile way. So those emotions that we both share, guilt, shame, anger, disgust, involved a social relationship that whether it was a norm violation, those are the kinds of emotions that are just like hunger and sexual attraction that are built into us by nature, by evolution. Or, if you wish, this is how God created the moral sentiments, just like He created everything else in the universe, through a process of nature. I think that’s equally reasonable to argue. So I don’t see that it has to be an atheistic viewpoint versus a theistic viewpoint to get to our moral sentiments. Why couldn’t God have used evolution to create the moral sentiments as I’ve described them?

GK: Yeah, well, you don’t actually believe that, I know, Mike, so this is kind of like adding God to the soup, you know, if it makes people feel better. But the basic argument is that evolution all by itself can do the trick. And I think if your listeners are listening carefully, what they’re going to hear is Mike has just described, and if I’m being unfair to your assessment here, let me know, Mike, that moral feelings are simply that. They are sophisticated emotions that do some work for us for survival, and even on a group level. Now there’s a name for this. It’s called emotivism. A.J. Ayer, the famous atheist, offered this description of morality. It’s a relativistic scheme of morality. Morality doesn’t actually exist, Ayer argued. There is no objective right or wrong. Rape isn’t wrong itself. What happens is, we have feelings about it, and we express it in moral language, but rape isn’t really wrong. So your listeners are going to have to ask themselves the questions. When they just survey their own moral senses, and we all have access to this, do we want to believe that scientists have figured out that really what we’re doing is feeling sophisticated, complicated emotions, and that the emotions are in us, and we are not seeing anything about the action? Or does it seem like rape is wrong? Look, when I say rape is wrong, I’m talking about the rape. When I say liver is awful, I’m talking about me. I’m talking about my own tastes and preferences. It’s interesting, as Michael has given his explanation, though, that he’s doing, and I don’t know if you are aware of this, Michael, but you’re doing the very thing that I kind of warned against. You give a description of the foundations of morality that turn out to be relativistic, but then there’s a smuggling of a more objectivistic morality in the back door, like when Michael says you don’t have to do what your nature tells you to do, in other words, what you’ve been programmed by evolution to do. You can kind of rise above that. Well, now we’re talking about a morality that isn’t dictated by evolution, but a morality that we can employ through our acts of will, to rise above this kind of brutish evolutionary morality. And that sounds suspiciously like the very thing that I’m talking about here.

MS: But I don’t mean, there’s nothing to rise above by itself. Yes, we have to say rise above our tribal instincts to be xenophobic when we meet somebody who’s a stranger, who’s different from us. We all struggle against that, particularly in a black and white America, where there’s always been this underlying tension. Indeed, so culture helps us do that – education, travel, diversity of exposure to different people. That makes you a little more tolerant. Okay, but I’m not talking about that. What I’m talking about is tapping into the good part of our nature, the fact that in addition to that xenophobic tribalism we have, we also have this other side that almost never gets discussed in evolutionary…even in evolutionary circles, you’ll still hear evolutionary biologists talking about, in a way that Huxley did, and Herbert Spencer did in Darwin’s own time, that we have to somehow struggle mightily against our genes to overcome that nasty tendency we have to want to rape, kill, pillage and destroy. Well no, actually, we have this whole other side that’s just as genetically programmed into our nature. And the point of culture – education, politics, economics and so on, is to tap into the better angels of our nature as Lincoln said.

GK: Okay, here’s the question I have for you, Michael, then. You’ve identified that really, we have good and we have bad. That’s part of, under your terms, that’s part of our genetic nature, and we can choose to tap into what you call the good side. Why ever should we do such a thing if there is not a higher standard that directs our action to the better side, your words, than the bad side, your words, if really, ultimately, they are both the result of a genetic evolution, and from outside terms, neither is better than the other. Why should we do that, Michael?

MS: Yeah, well I don’t see how entering God into the equation changes that problem at all.

GK: Well, that’s the next step. What I’m trying to show is that the should comes from the outside, and if we can demonstrate that, then we can ask…
