- 0:00Reformed thinking. Welcome to the deep dive.
- 0:03Today, we have a really big task ahead of us.
- 0:06We're tackling a stack of source material that cuts straight to
- 0:09the root of, you know, our whole moral experience as human
- 0:12beings. We aren't really getting into
- 0:14what is right or wrong today, but something much more
- 0:16fundamental. Where does the whole idea of
- 0:19right and wrong even come from? That's right.
- 0:22Our listeners sent in sources that draw heavily on CS Lewis's
- 0:25work, specifically his his very clear, very accessible
- 0:29discussion on what he calls the moral law.
- 0:32He's really focused on setting a foundation here.
- 0:34You have to remember Lewis and his day was dealing with a world
- 0:37that was pretty confident that this whole concept of a natural
- 0:41law, of a real right and wrong could be easily explained away.
- 0:44And it seems like not much has changed.
- 0:46So our mission today is really to solidify that foundation for
- 0:49you, the listener. We're going to do a deep dive
- 0:51into two of the classic objections that honestly, if
- 0:54they hold up, they kind of dismantle any claim to an
- 0:57objective morality. The first one is that morality
- 1:00is nothing but biological instinct.
- 1:02And the second is that it's just a social convention that changes
- 1:05over time. So we need to see how Lewis just
- 1:08systematically with pure logic takes both of these arguments
- 1:12apart. And this isn't just some, you
- 1:14know, academic exercise getting a handle on why the moral law
- 1:17can't be boiled down to biology or just arbitrary social rules.
- 1:22It's the prerequisite for any meaningful conversation about
- 1:25human nature, about accountability, and about
- 1:27whether there's a standard that stands over all of us.
- 1:30If Lewis's arguments hold, it changes the entire ethical
- 1:33playing field for you. OK, let's unpack this, starting
- 1:36with that first and probably most common objection.
- 1:39A lot of people today will suggest that what we call the
- 1:42moral law, this rule of decent behavior, is really just a
- 1:45sophisticated form of herd instinct.
- 1:47It's just a biological Dr. that developed to help the species
- 1:50survive. You know, like a mother's love
- 1:52for her child or the instinct to find food.
- 1:54It's evolution making rules so the group can stick together.
- 1:57It's a very compelling claim in our modern world, isn't it?
- 2:00Because it seems to anchor morality in something real,
- 2:03something tangible or biology. And Linda is quick to
- 2:07acknowledge that yes, of course we have instincts, we have
- 2:09desires that push us to help other people.
- 2:12But he immediately draws this razor sharp distinction between
- 2:15the internal push, the want that we feel, and what he calls the
- 2:19external command, the ought that we recognize.
- 2:23That's really the whole crux of it, isn't it?
- 2:24The difference between want and ought It is if the moral law is
- 2:29just another instinct, it would always speak the language of
- 2:32desire. It would say I want to help.
- 2:34But if it's something different, something else, it speaks the
- 2:37language of obligation. It says I ought to help even if
- 2:40I don't want to. Precisely.
- 2:42And to make this crystal clear, let's use Lewis's classic
- 2:45scenario. It illustrates this crucial
- 2:48difference perfectly. The Drowning Man.
- 2:49The drowning Man. So imagine you're there.
- 2:52You witness a truly dangerous situation.
- 2:55You see someone struggling in rough water and it's clear they
- 2:59are drowning inside you. In that very instant, 2 very
- 3:03powerful, very conflicting instincts just erupt.
- 3:06The first would be that impulse to help right?
- 3:09What we call the herd instinct or sympathy.
- 3:11You feel a pull to jump in, Yes. But the second one, and let's be
- 3:15honest, it's often much much stronger, is the instinct for
- 3:17self preservation. It's that powerful, primal
- 3:21desire to stay safe, to not get yourself killed.
- 3:25So you have two voices screaming at you at the same time.
- 3:27Help and run. Exactly.
- 3:30Just two competing forces, 2 distinct desires pulling you in
- 3:34opposite directions. Now, if morality were only
- 3:37instinct, the story would end right there.
- 3:40Meaning the stronger one would just win out.
- 3:42You would have to. You'd feel the stronger pull and
- 3:44you do that thing if self preservation one, maybe you'd
- 3:46walk away feeling a bit uncomfortable, but you wouldn't
- 3:48feel a deep sense of moral failure.
- 3:50It would just be biology doing its thing.
- 3:52But Lewis says that's not our actual experience.
- 3:55He says there's a third thing present in that moment.
- 3:58There is absolutely a third thing, and that third thing is
- 4:01this awareness, this feeling that you should suppress the
- 4:05imulse to run away, even if that desire to run is overwhelmingly
- 4:09strong, and that you should follow the imulse to help even
- 4:12if the idea of helping is terrifying.
- 4:14This third thing is the judge. It sits above the instincts.
- 4:18It's not one of them, it's the director.
- 4:20That's the logical step. Then the thing that is judging 2
- 4:22other things, telling you which one to listen to and which one
- 4:25to ignore. It can't logically be one of the
- 4:27things it's judging. It's structurally impossible for
- 4:30it to be, and the analogy Lewis gives here is just it's perfect.
- 4:33The piano and the sheet music are biological instincts, self
- 4:37preservation, herd instinct, hunger, the sexual drive.
- 4:41All of them. Those are the keys on the piano.
- 4:43They're just the raw material. They're the mechanisms that let
- 4:45us act. But the moral law, that's the
- 4:48sheet music. It's the instruction manual.
- 4:50Yes. The sheet music tells you when
- 4:52to play a specific key, how hard you should hit it, and when you
- 4:55should just leave it alone entirely.
- 4:58The sheet music itself is not made of ivory and wood.
- 5:00It's not one of the keys. So if the sheet music says play
- 5:03AC sharp and the C# key itself pipes up and says wait a minute,
- 5:07I am the sheet music, the whole system just collapses into
- 5:10nonsense. It's a category error.
- 5:12The law, the instruction, is external to the biological
- 5:16mechanism. The instinct that it's
- 5:17commanding, The tune we're supposed to play, which is good
- 5:20conduct, is created by the law directing the keys at just the
- 5:24right moment. The very existence of that
- 5:27judging faculty inside you proves the moral law is
- 5:30something separate from the raw material of your desires.
- 5:33OK, so that brings us to a second really critical point
- 5:36that Lewis makes about the strength of these impulses.
- 5:39If morality were simply the stronger instinct winning out
- 5:42the outcome would just be a matter of biological intensity.
- 5:45But what we find is that the moral law often tells us to do
- 5:48the exact opposite. This is an incredibly persuasive
- 5:50point because it uses our own inner experience against that
- 5:54deterministic biological view. How so?
- 5:56Well, think about physics. If two physical forces collide,
- 5:59the stronger one wins. Period.
- 6:01End of story. So if the instinct for your own
- 6:04safety is biologically stronger than the instinct to help a
- 6:06complete stranger. Then safety has to win every
- 6:09time. It must win, and what we call
- 6:12morality would just be the story we tell ourselves afterwards to
- 6:15justify why the strongest impulse won.
- 6:18But our conscience doesn't work like that.
- 6:20It tells us we have to help the drowning person, even though if
- 6:22we're being really honest with ourselves, our raw physical or
- 6:26emotional want for our own safety is probably overwhelming
- 6:29in that moment. You're likely to desire your own
- 6:32safety far, far more strongly than you desire to help that
- 6:35stranger. And that's the absolute
- 6:37contradiction for the instinct theory.
- 6:39The moral law consistently commands us to obey what Lewis
- 6:43calls the weaker impulse. It requires self sacrifice.
- 6:47It requires the suppression of our primal self-interest.
- 6:50Now someone might argue, while maybe over millions of years the
- 6:53herd instinct has actually become the dominant one because
- 6:55communal survival helps individual survival, so maybe
- 6:59the stronger long term instinct is the one that wins out.
- 7:02And that's the more sophisticated evolutionary
- 7:04challenge. You're right, but Lewis's logic
- 7:06still holds up because the moral law isn't acting like a
- 7:10statistician. You know, averaging out what's
- 7:13best for the group over the next 1000.
- 7:14Years. No, it's immediate.
- 7:16It's an immediate commander making a singular binding demand
- 7:20in a moment of peril. In that instant when those two
- 7:24instincts are really colliding head on, the moral law sides
- 7:27with the one that feels weaker, less urgent, and frankly, more
- 7:30dangerous to you personally. So it can't be the sum of our
- 7:33instincts or even the average of them.
- 7:35It has to be an independent rule, some kind of standard that
- 7:38we use to weigh the competing instincts against each other.
- 7:41Yes. If it were just the sum, it
- 7:43would reflect the loudest voice in the room, the most dominant
- 7:46feeling. It would be the loudest note on
- 7:48the piano, but instead it's that quiet external voice that says,
- 7:52look, despite your fear, despite the intensity of your survival
- 7:56impulse. The rule here requires this
- 7:58specific, difficult action, and that shows that the moral law is
- 8:04prescriptive. It prescribes behavior based on
- 8:06a rule, not descriptive, which would just describe whatever
- 8:09action came from the strongest biological drive.
- 8:11It gives us a little glimpse of something that's outside the
- 8:13biological system entirely. So let's look at a third way.
- 8:16Lewis pulls the law and instinct apart.
- 8:18This one focuses on those times when we feel a moral duty to,
- 8:22well, to kind of manufacture a feeling that we don't actually
- 8:25have. I mean, if the moral law was
- 8:27really just an instinct, why would we ever feel like we have
- 8:30a duty to strengthen it? This really gets at what you
- 8:33might call the coldness of duty. There's so many times when we
- 8:36know what we ought to do, but we check our emotional gas tank and
- 8:39it's empty. Our pity, our compassion, our
- 8:41willingness to help. It's just not there and yet we
- 8:45feel this internal mandate. You need to wake up your herd
- 8:49instinct. You need to get it going.
- 8:51We have to actively generate the emotional steam, as Lewis calls
- 8:55it, just to get ourselves to do the right thing.
- 8:58I feel this sometimes when I have to deal with, say, a
- 9:01difficult neighbor or a frustrating family situation.
- 9:04My natural goodwill is just gone, but I know I should feel
- 9:08pity or patience, so I have to almost force myself to conjure
- 9:11it up. And that intentional act of
- 9:13conjuring is the key piece of evidence.
- 9:15How can the thing that needs to be awakened be the very same
- 9:18thing that's giving the command to wake up?
- 9:20Can't be. The command is the moral law.
- 9:22The thing being commanded is the instinct.
- 9:24The sheet music can tell the pianist you need more volume on
- 9:27this part, but the sheet music is not the volume knob.
- 9:30The 2 are separate. So if I feel an obligation to
- 9:32really focus my mind on what a suffering person is going
- 9:35through, specifically so I can generate a feeling of pity that
- 9:39isn't there, naturally, that proves the obligation itself
- 9:43came from a standard that's higher than my current dormant
- 9:46feeling of pity. It shows the legislative quality
- 9:49of the moral law. It's like a law giver.
- 9:52It isn't satisfied with the strength of the instinct as it
- 9:55finds it. It demands a level of emotional
- 9:58input, a level of action that goes beyond our current natural
- 10:02state. This separates the moral law not
- 10:04just from our strong instincts, but also from our weak ones.
- 10:07And it really demonstrates its supervisory role over the whole
- 10:11array of our internal drives. Right, because if morality were
- 10:13just biological, we just do whatever action corresponds to
- 10:16the feelings we happen to have at the moment.
- 10:18And we wouldn't feel bad about it.
- 10:20The fact that we feel guilty for not having the right feelings
- 10:23and then feel duty bound to try and cultivate them demonstrates
- 10:26the independence of law from the feelings it governs.
- 10:29OK, this leads right into a common misunderstanding that
- 10:31comes out of the instinct theory.
- 10:34And that's the idea that some of our impulses are just inherently
- 10:37good, like mother love or patriotism, and others are
- 10:40inherently bad, like sex or aggression.
- 10:43If the moral law were just an instinct, we should be able to
- 10:46point to one of them that is always, in every single
- 10:49situation, the right one to follow.
- 10:51And Lewis basically challenges anyone to find such an instinct.
- 10:54He says very firmly that it just doesn't exist.
- 10:58He reclassifies all our impulses as being fundamentally neutral.
- 11:02They're just tools. They're the piano keys.
- 11:04No single key on a piano is inherently a wrong note.
- 11:08Every note is correct at one time and incorrect at another.
- 11:11It all depends on the tune that the sheet music is calling for.
- 11:14Can you walk us through that with an impulse that seems
- 11:16purely good, like a mother's love for her child?
- 11:18How can that become morally wrong if it's not directed by
- 11:21something else? Of course, take mother love in
- 11:24its proper place. It's a beautiful, powerful
- 11:26thing. But if a mother elevates her
- 11:28fierce devotion to her own child above the rule of justice, her
- 11:32love becomes destructive. For example, if she lies to
- 11:34protect your child from consequences he deserves, or if
- 11:37she, say, steals resources meant for other children just to
- 11:41benefit her own, then her impulse, no matter how strong or
- 11:44pure it felt to her, is now directing her toward injustice.
- 11:49The moral law is what commands her to suppress that fierce
- 11:52protective instinct in favor of fairness to everyone.
- 11:55And on the flip side, those impulses that society often
- 11:58labels as bad or dangerous? The fighting instinct, for
- 12:01instance, are sometimes the very thing the moral law commands us
- 12:05to use. Absolutely.
- 12:06The fighting instinct, you could call it aggression or righteous
- 12:09anger, is clearly required when you have to defend someone who's
- 12:12vulnerable. If a soldier is called to defend
- 12:14their people from an invader, or a person has to defend a victim
- 12:17from an assault, the moral law actually commands them to
- 12:20encourage and use that instinct. The point is, the impulse itself
- 12:23has no intrinsic moral value. The moral value is only in the
- 12:27instruction that commands the impulse at the right time and in
- 12:30the right measure. So the moral law isn't just a
- 12:32list of our instincts, it's more like the master Carpenter who
- 12:36knows how to arrange all the different tools.
- 12:38And if you take any single tool and make it the master the whole
- 12:41project, your life, your conduct is going to end up crooked and
- 12:45dangerous. That is the big practical
- 12:48consequence. Lewis warns about the danger of
- 12:50absolutizing any single impulse. If you pick one internal drive,
- 12:56even the one that seems as noble as, say, compassion for the
- 13:00suffering, and you set it up as the one thing to follow at all
- 13:03costs, you very quickly find yourself having to negate other
- 13:07virtues like truth and justice. I think we should pause on this
- 13:10because it's so relevant to modern conversations.
- 13:13If a person decides that love of humanity is their ultimate moral
- 13:16guide, they might start to justify some truly terrible
- 13:19actions. The outcomes are often
- 13:20terrifying. If the overall benefit of
- 13:23humanity is your absolute goal, and you leave out the need for
- 13:25justice or truthfulness, which are also directed by the moral
- 13:28law, you can start to rationalize things like breaking
- 13:32sworn agreements with a minority group, or manipulating public
- 13:35opinion with lies, or even fabricating evidence and trials,
- 13:39all under the banner of serving some greater benevolent cause.
- 13:43By following that one impulse absolutely, you become
- 13:46treacherous and cruel in the pursuit of what you thought was
- 13:49good. And that just proves again that
- 13:51the moral law has to be this balanced director, external to
- 13:54all our internal motivations and supervising them.
- 13:57It does. It firmly establishes the
- 13:59conclusion for this first part of our deep dive.
- 14:01Yeah, The moral law is not a description of our biological
- 14:04urges. It's a prescriptive standard
- 14:06that governs them. We've successfully disconnected
- 14:09the ought from the want. OK, so if the moral law isn't
- 14:12rooted in our biology, the next most obvious objection
- 14:15immediately comes up. It must just be a social
- 14:18convention. It's just something we're
- 14:19taught. It's passed down through
- 14:20education, from our parents, from our society.
- 14:23Therefore, it's something humans invented, and it can be changed
- 14:27by cultural whim. This is the other major
- 14:29reductionist move. It's an attempt to strip the law
- 14:32of any claim to reality. It wants to suggest that
- 14:35morality is arbitrary, like fashion trends or which side of
- 14:39the road we drive on. But Lewis, right away, he
- 14:43tackles this misunderstanding that's built into the objection.
- 14:46He clarifies the massive difference between learning
- 14:49something and something being a human invention.
- 14:52Right. When we are taught the rule of
- 14:55decent behavior, we are definitely learning it from
- 14:58external sources, from our culture.
- 15:00But learning something doesn't automatically mean it was
- 15:02invented. If I learned that in my country
- 15:04we drive on the right side of the road, that's clearly an
- 15:07invention, a convention. It could have just as easily
- 15:09been the left. Exactly.
- 15:11Driving on the right is a rule, but it's an arbitrary one.
- 15:14It's something we chose as a group, and we could have chosen
- 15:16differently without any problem. But Lewis asked us to consider
- 15:20the other category of things we learn things that are real
- 15:22truths, totally independent of our choice.
- 15:25And the classic parallel he uses here is mathematics.
- 15:28Yes, we all learn the multiplication table at school.
- 15:32It's taught to us entirely through instruction.
- 15:35A child who was raised completely alone on an island
- 15:38would be ignorant of it. So does that mean the
- 15:41multiplication table is just a convention that humans invented
- 15:44it and we could have all just agreed that 2 * 2 = 5?
- 15:47Of course not. It's absurd on its face.
- 15:50The multiplication table describes a real truth about
- 15:53reality. It existed before humans ever
- 15:55formalized it, and it'll continue to be true whether any
- 15:58single society acknowledges it or not.
- 16:00It is discovered not invented. So the essential question for
- 16:04the moral law becomes which of these two categories does it
- 16:07belong in? Is it like the arbitrary rule of
- 16:09the road or is it like the fixed truth of the multiplication
- 16:13table? That's the question.
- 16:14If it's like the rule of the road, then we can change it
- 16:17whenever it's convenient for us, and no version is truer or
- 16:20better than any other. But it's like mathematics.
- 16:22Then we might learn it gradually, we might
- 16:24misunderstand parts of it, we might apply it imperfectly.
- 16:27But the rule itself remains fixed, real and mandatory.
- 16:31And Lewis argues very strongly that it belongs in that second
- 16:34category. So what's the first piece of
- 16:36evidence he brings to the table to put the moral law in the same
- 16:39class as an independent truth like math?
- 16:42He asks us to just look at the evidence, to look at the
- 16:45consistency across different cultures and throughout history.
- 16:48Now, critics love to focus on the differences in moral codes.
- 16:51And yes, of course there are differences.
- 16:53But Lewis asserts that those differences are vastly
- 16:56exaggerated. What people so often overlook is
- 17:00the profound, overwhelming common ground.
- 17:04So if we look at the laws of, say, the ancient Babylonians,
- 17:08the Chinese, the Greeks, and compare them to modern society,
- 17:11we find that while the specific penalties or applications of
- 17:13justice might differ, the core principle of justice that you
- 17:17shouldn't murder, that you should honor agreements, that
- 17:19you should respect property, is universally present.
- 17:21That underlying common law is the key.
- 17:23Think about things that are genuine conventions, like
- 17:26clothing or table manners. Those can differ entirely to any
- 17:30degree you can imagine without any logical contradiction.
- 17:34The way someone eats with chopsticks in China is
- 17:36completely different from the way someone eats with a fork and
- 17:38knife in England. But neither custom contradicts
- 17:41the other. They're just arbitrary.
- 17:43But a moral principle that says it is wrong to torture an
- 17:47innocent person for amusement it you can't just have another
- 17:50culture arbitrarily invert that without fundamentally
- 17:54contradicting the common moral sense of humanity.
- 17:57Right. That relative uniformity of
- 17:59these basic moral principles suggests that we're all dealing
- 18:02with a response to the same objective reality.
- 18:05Even the apparent contradictions, like tribal laws
- 18:08that say you should only be kind to people within your own tribe.
- 18:11That's not actually a rejection of the moral law.
- 18:14It's just an imperfect application of a universal rule.
- 18:16Treat your neighbor justly, but with a mistaken tunary
- 18:19definition of who qualifies as your neighbor.
- 18:22They're affirming the rule even while miss applying its scope.
- 18:25And that underlying rule remains intact and consistent, which is
- 18:29the hallmark of a real truth, not a shifting convention.
- 18:32OK, now let's turn to the second, and I would argue the
- 18:35most potent refutation of this whole convention theory.
- 18:39And that's the logical requirement that's embedded in
- 18:41the very idea of moral progress. We talk about moral progress all
- 18:45the time, but what does that word progress actually require
- 18:49for it to make any sense? Progress is such a powerful
- 18:53word, and it's a logical minefield for the moral
- 18:56relativist. Because progress doesn't just
- 18:59mean change. If I change my shirt from a blue
- 19:011 to a red one, that's just a change.
- 19:04Progress means changing for the better.
- 19:06It means moving toward a more correct state.
- 19:08So if all moral ideas were just conventions, just arbitrary
- 19:11rules made-up by different groups at different times, then
- 19:14one set of ideas couldn't possibly be better or truer than
- 19:17another. They would just be different,
- 19:18like changing your currency from the franc to the euro.
- 19:21If morality is purely conventional, there is no
- 19:24logical basis whatsoever to prefer, say, civilized morality
- 19:29over savage morality, or to argue that the 21st centuries
- 19:32views on human rights are in any way superior to the 16th
- 19:35centuries views. That just be alternative social
- 19:37operating systems. And if we really, truly believe
- 19:41that, we couldn't criticize the moral code of any society, and
- 19:44that includes the worst atrocities in human history.
- 19:47But we absolutely do criticize them.
- 19:49We use words like reformers and pioneers for historical figures,
- 19:52people like the abolitionists or the leaders of the civil rights
- 19:55movement who challenged the accepted morality of their own
- 19:58time. The very act of calling them a
- 20:01reformer implies they saw the truth that their contemporaries
- 20:04were missing. The second you use the language
- 20:06of improvement or reform or getting near to the truth, you
- 20:09have logically admitted that there is an external fixed
- 20:13standard of behavior. That standard is the real
- 20:16morality that has to exist independent of both reformers
- 20:20new ideas and the conventional ideas of his age.
- 20:23So without that external standard, the reformer isn't
- 20:26progressing towards anything. He's just arguing for a new
- 20:29arbitrary convention to replace the old arbitrary convention.
- 20:32The debate wouldn't be about right and wrong, it would just
- 20:35be about which arbitrary system is more convenient or preferable
- 20:39to a certain group. Our ability to criticize past
- 20:42moral systems, or even to feel guilt about our own failures,
- 20:46depends on the assumption of this fixed standard.
- 20:49It does when we judge the past. Let's take the practice of
- 20:53slavery. We aren't judging it by our
- 20:55modern convention. We're judging it by a rule of
- 20:58justice that we believe ought to have applied back then, just as
- 21:01it applies now. This standard is the reference
- 21:04point. It's the reality that makes the
- 21:06very concept of progress logically possible.
- 21:09And this brings us right to Lewis's analogy that connects
- 21:12moral truth to an objective, independent reality.
- 21:16To judge whether any idea is true, there has to be a reality
- 21:19that exists apart from the idea itself.
- 21:21Let's use this example of the city of New York.
- 21:23My mental idea of New York can be judged as being truer or less
- 21:27true than your mental idea of New York for one reason and one
- 21:29reason only. Because New York is a real
- 21:31place. Because New York is a real place
- 21:33that exists outside of both of our minds, we can check our
- 21:36imperfect mental maps against the external reality of the city
- 21:39itself. If New York simply meant the
- 21:41imaginary city that's currently in my head, then there would be
- 21:44no truth or falsehood involved in describing it.
- 21:46There would only be difference. My idea would be true for me and
- 21:50your idea would be true for you. Now apply that same powerful
- 21:54logic to the moral law. If the rule of decent behavior
- 21:57simply meant whatever each nation happens to approve of at
- 22:01the moment, then there would be no truth involved.
- 22:04We couldn't say that the world could ever grow morally better
- 22:06or morally worse over time. We could only say that it has
- 22:10changed his mind. And since we as a society
- 22:13constantly evaluate the morality of the past and believe that
- 22:15humanity has in fact made genuine moral advances, I mean
- 22:19moving away from things like public torture or summary
- 22:21executions or widespread injustice, that very belief
- 22:25requires an independent standard to measure against.
- 22:28The very concept of moral improvement is the logical
- 22:31guillotine for the convention theory.
- 22:33It just cuts his head clean off. The moral law must be a real
- 22:37natural law, like gravity or like mathematics, something that
- 22:40we may learn about slowly, something we apply
- 22:43inconsistently, and something we misunderstand frequently, but it
- 22:46exists outside of our subjective opinions and our cultural
- 22:49choices. It's the truth about how humans
- 22:51ought to behave, whether we have the courage or the wisdom to
- 22:55fully follow it or not. Yes.
- 22:57So we've now shown that the moral law is neither determined
- 22:59by our internal desires nor is it invented by our social
- 23:03contracts. It stands as an external real
- 23:05standard. Now that we've established the
- 23:07reality and independence of the moral law, let's circle back to
- 23:11really practical issues. First, let's revisit the danger
- 23:14of confusing the law with a single impulse.
- 23:17And 2nd, we need to clarify how differences in moral codes are
- 23:20so often based on errors of fact, not errors of principle.
- 23:24We really do need to reaffirm the practical danger of
- 23:26elevating any single internal impulse, no matter how good it
- 23:29seems, to the status of the absolute moral law.
- 23:33Lewis is very clear that doing this leads to moral ruin.
- 23:36It seems a bit counterintuitive, though.
- 23:38How can you criticize an impulse like generalized compassion?
- 23:42What makes taking that as your guide so destructive?
- 23:45Because the moral law isn't a single virtue.
- 23:48It's a complex tune. It's played with many different
- 23:51keys. Justice, truth, temperance,
- 23:54fairness and compassion all have their part.
- 23:57To take just one of those instruments and make it the sole
- 23:59guiding star is to throw away the rest of the musical score.
- 24:03So if I choose to follow compassion alone, I might have
- 24:06to sacrifice justice. If I choose to follow fairness
- 24:09alone, I might have to sacrifice mercy.
- 24:11Exactly. Let's take the love of humanity
- 24:13again. If that is your absolute guide
- 24:15and you were trying to implement a system that you believe will
- 24:18greatly benefit the majority of people, you might find that to
- 24:21achieve that goal you have to break agreements with certain
- 24:24individuals. Or lie to a specific subset of
- 24:27people, or even imprison people without due process.
- 24:30And you would justify these localized cruelties by saying
- 24:32it's for the sake of the greater good?
- 24:34But in doing so, you're violating the moral laws demand
- 24:37for justice and for truthfulness.
- 24:39Yes, you become treacherous and in the end cruel, all while
- 24:43believing you are being highly moral.
- 24:46That very action proves that the moral law is the impartial
- 24:50director that commands a balance between all these competing
- 24:52duties. It ensures that no single
- 24:55impulse, not even a benevolent 1, is allowed to destroy the
- 24:58whole moral life. The law forces us to see that
- 25:02all our natural desires are just raw material, and none of them
- 25:05on its own has the authority to command the others.
- 25:08OK, finally, let's tackle that appearance of extreme moral
- 25:11differences that relativists love to point to.
- 25:13For instance, the historical practice of executing people who
- 25:16are accused of being witches. People, stop doing that.
- 25:19So hasn't morality just changed drastically?
- 25:21This is such a crucial area where, you know cultural studies
- 25:24can get it wrong. They often conflate differences
- 25:26in the application of a principle with a difference in
- 25:28the underlying principle itself. Lewis demands we draw off a very
- 25:32sharp line between a difference in moral principle and a
- 25:35difference in factual belief. So in the case of executing a
- 25:38witch, what was the underlying moral principle at play?
- 25:41The principle was that heinous, destructive treason actions that
- 25:44cause severe harm to the community, like killing your
- 25:46neighbors or bringing about sickness, deserves the death
- 25:50penalty. That core principle, that severe
- 25:52crime deserves severe punishment, is consistent across
- 25:55almost all human societies. The moral principle itself
- 25:59didn't change. The factual belief change.
- 26:01Precisely the people in the 16th century genuinely believed, as a
- 26:05matter of cold, hard fact, that certain individuals were selling
- 26:08their souls to malevolent forces, gaining supernatural
- 26:11powers, and then actively using them to ruin crops, murder
- 26:15children, and cause chaos. They view these accused people
- 26:19as, in Lewis's words, filthy quizlings who were literally
- 26:23destroying the community from within through supernatural
- 26:26means. And I suppose if we today
- 26:29factually believed that our next door neighbor had the
- 26:31supernatural ability to kill our child just by wishing it, and
- 26:34that they were actively doing so, we would probably agree they
- 26:37should be removed from society and maybe even executed.
- 26:39That is Lewis's stark assertion. We stopped executing them not
- 26:43because we rejected the moral rule that destructive evil
- 26:46should be punished. We stopped executing them
- 26:48because we stopped believing the fact of their existence or the
- 26:52fact of their alleged powers. That makes the distinction
- 26:54incredibly clear. So moral advance is often just a
- 26:57factual advance or a scientific advance, not a change in the
- 27:01core moral rule. That's it.
- 27:03The man who stopped setting mouse traps because he finally
- 27:05realizes there are no mice in his house isn't a more humane
- 27:09man. His factual premise has simply
- 27:11been updated. There's no moral advance in not
- 27:15punishing something you no longer think is there.
- 27:17And this helps us see the consistency of the moral law.
- 27:19When we look at ancient societies, their moral codes are
- 27:22often just these universal principles, like justice, being
- 27:25applied to their specific and sometimes very inaccurate
- 27:28beliefs about how the world works.
- 27:30The rule stays the same. Do not harm the innocent.
- 27:33The factual question that changes is who counts as
- 27:36innocent and what actions actually cause harm.
- 27:39The core principles of justice, fairness and truth telling
- 27:42remain remarkably consistent, which points us again to a real
- 27:46external standard. So after all this, what does it
- 27:48all mean for us, for the listener thinking this through?
- 27:51It means that the moral law successfully resists being
- 27:54reduced. It isn't some arbitrary rule we
- 27:57invented for our own convenience, nor is it merely A
- 28:00biological feeling that developed to help us survive.
- 28:03It is an independent, fixed standard that applies to
- 28:06humanity everywhere and always. It's a fact about reality that
- 28:09dictates how we ought to behave, regardless of how we want to
- 28:13behave at any given moment. And the necessary conclusion of
- 28:15this deep dive, then, is that if this rule of decent behavior is
- 28:19a real, fixed external truth, like the laws of mathematics are
- 28:23a real truth, then we have to seriously confront the question
- 28:26of its source. If the instincts are the piano
- 28:29keys and our conducts is the tune, and the moral law is the
- 28:32sheet music directing that tune. We are forced to ask who wrote
- 28:36the sheet music, that external prescriptive standard which
- 28:41holds us accountable even when we defy our strongest desires
- 28:45and stands independent of all our collective opinions.
- 28:48It points compellingly toward a law giver, toward a mind or a
- 28:52will that stands behind the very structure of right and wrong
- 28:55and. That's a question that demands
- 28:57an answer that goes far beyond mere instinct or convention.
- 29:00Thank you for guiding us through this foundational logic today.
- 29:02Is my pleasure. Until next time, keep thinking.
