Grief, a rationalist perspective

This post goes live on the 8th anniversary of my father’s death. Thus it seems an appropriate time to write about grief—indeed, it’s somewhat difficult for me to think about much else.

Far too often, the only perspectives on grief we hear are religious ones. Often, these take the form of consolation: “He’s in a better place now.” “You’ll see him again someday.”

Rationalism doesn’t offer such consolations. Technically one can be an atheist and still believe in an afterlife; but rationalism is stronger than mere atheism. It requires that we believe in scientific facts, and the permanent end of consciousness at death is a scientific fact. We know from direct experiments and observations in neuroscience that a destroyed brain cannot think, feel, see, hear, or remember—when your brain shuts down, whatever you are now will be gone.

It is the Basic Fact of Cognitive Science: There is no soul but the brain.

Moreover, I think, deep down, we all know that death is the end. Even religious people grieve. Their words may say that their loved one is in a better place, but their tears tell a different story.

Maybe it’s an evolutionary instinct, programmed deep into our minds like an ancestral memory, a voice that screams in our minds, insistent on being heard:

“Death is bad!”

If there is one crucial instinct a lifeform needs in order to survive, surely it is something like that one: The preference for life over death. In order to live in a hostile world, you have to want to live.

There are some people who don’t want to live, people who become suicidal. Sometimes even the person we are grieving was someone who chose to take their own life. Generally this is because they believe that their life from then on would be defined only by suffering. Usually, I would say they are wrong about that; but in some cases, maybe they are right, and choosing death is rational. Most of the time, life is worth living, even when we can’t see that.

But aside from such extreme circumstances, most of us feel most of the time that death is one of the worst things that could happen to us or our loved ones. And it makes sense that we feel that way. It is right to feel that way. It is rational to feel that way.

This is why grief hurts so much.

This is why you are not okay.

If the afterlife were real—or even plausible—then grief would not hurt so much. A loved one dying would be like a loved one traveling away to somewhere nice; bittersweet perhaps, maybe even sad—but not devastating the way that grief is. You don’t hold a funeral for someone who just booked a one-way trip to Hawaii, even if you know they aren’t ever coming back.

Religion tries to be consoling, but it typically fails. Because that voice in our heads is still there, repeating endlessly: “Death is bad!” “Death is bad!” “Death is bad!”

But what if religion does give people some comfort in such a difficult time? What if supposing something as nonsensical as Heaven numbs the pain for a little while?

In my view, you’d be better off using drugs. Drugs have side effects and can be addictive, but at least they don’t require you to fundamentally abandon your ontology. Mainstream religion isn’t simply false; it’s absurd. It’s one of the falsest things anyone has ever believed about anything. It’s obviously false. It’s ridiculous. It has never deserved any of the respect and reverence it so often receives.

And in a great many cases, religion is evil. Religion teaches people to be obedient to authoritarians, and to oppress those who are different. Some of the greatest atrocities in history were committed in the name of religion, and some of the worst oppression going on today is done in the name of religion.

Rationalists should give religion no quarter. It is better for someone to find solace in alcohol or cannabis than for them to find solace in religion.

And maybe, in the end, it’s better if they don’t find solace at all.

Grief is good. Grief is healthy. Grief is what we should feel when something as terrible as death happens. That voice screaming “Death is bad!” is right, and we should listen to it.

No, what we need is to not be paralyzed by grief, destroyed by grief. We need to withstand our grief, get through it. We must learn to be strong enough to bear what seems unbearable, not console ourselves with lies.

If you are a responsible adult, then when something terrible happens to you, you don’t pretend it isn’t real. You don’t conjure up a fantasy world in which everything is fine. You face your terrors. You learn to survive them. You make yourself strong enough to carry on. The death of a loved one is a terrible thing; you shouldn’t pretend otherwise. But it doesn’t have to destroy you. You can grow, and heal, and move on.

Moreover, grief has a noble purpose. From our grief we must find motivation to challenge death, to fight death wherever we find it. Those we have already lost are gone; it’s too late for them. But it’s not too late for the rest of us. We can keep fighting.

And through economic development and medical science, we do keep fighting.

In fact, little by little, we are winning the war on death.

Death has already lost its hold upon our children. For most of human history, nearly a third of children died before the age of 5. Now less than 1% do, in rich countries, and even in the poorest countries, it’s typically under 10%. With a little more development—development that is already happening in many places—we can soon bring everyone in the world to the high standard of the First World. We have basically won the war on infant and child mortality.

And death is losing its hold on the rest of us, too. Life expectancy at adulthood is also increasing, and more and more people are living into their nineties and even their hundreds.

It’s true, there still aren’t many people living to be 120 (and some researchers believe it will be a long time before this changes). But living to be 85 instead of 65 is already an extra 20 years of life—and these can be happy, healthy years too, not years of pain and suffering. They say that 60 is the new 50; physiologically, we are so much healthier than our ancestors that it’s as if we were ten years younger.

My sincere hope is that our grief for those we have lost and fear of losing those we still have will drive us forward to even greater progress in combating death. I believe that one day we will finally be able to slow, halt, perhaps even reverse aging itself, rendering us effectively immortal.

Religion promises us immortality, but it isn’t real.

Science offers us the possibility of immortality that’s real.

It won’t be easy to get there. It won’t happen any time soon. In all likelihood, we won’t live to see it ourselves. But one day, our descendants may achieve the grandest goal of all: Finally conquering death.

And even long before that glorious day, our lives are already being made longer and healthier by science. We are pushing death back, step by step, day by day. We are fighting, and we are winning.

Moreover, we as individuals are not powerless in this fight: you can fight death a little harder yourself, by becoming an organ donor, or by donating to organizations that fight global poverty or advance medical science. Let your grief drive you to help others, so that they don’t have to grieve as you do.

And if you need consolation from your grief, let it come from this truth: Death is rarer now today than it was yesterday, and will be rarer still tomorrow. We can’t bring back who we have lost, but we can keep ourselves from losing more so soon.

The scissors of supply and demand

In recent posts I talked about demand and then I talked about supply. Now it’s time to talk about both at once–which is where the real magic happens. Alfred Marshall famously compared supply and demand to the lower and upper blades of a pair of scissors:

We might as reasonably dispute whether it is the upper or the under blade of a pair of scissors that cuts a piece of paper, as whether value is governed by utility or cost of production. It is true that when one blade is held still, and the cutting is effected by moving the other, we may say with careless brevity that the cutting is done by the second; but the statement is not strictly accurate, and is to be excused only so long as it claims to be merely a popular and not a strictly scientific account of what happens.

~Alfred Marshall, Principles of Economics

Before Marshall, it was actually rather common to debate whether prices are determined by supply or by demand. Actually there seems to be a certain branch of Marxists today who insist upon the “labor theory of value” that seems to rest upon a similar sort of confusion, basically saying that the real value of something is entirely determined by its cost of supply. If the value of something were strictly determined by the labor put into making it, there would be literally no reason to ever make anything. If the value you get from a good is precisely equal to the labor put into it, there is no net benefit to ever making any goods. At most, embodying labor in a product might allow you to transfer labor from one person to another; but there would be no such thing as real economic growth. In order to have real economic growth, products must end up being worth more than what it cost to make them—that is, their value of demand must exceed their cost of supply.

Toward the other end of the political spectrum, we have “Say’s Law”, which says that “supply creates its own demand”; that is, that there is never any such thing as too much or too little overall demand in an economy, because supplying a good automatically makes that good available to trade for something else. I hate to even call it a “law” because isn’t even like the Pirate Code; it’s not even useful as a guideline, it’s just flat wrong. There is absolutely no reason that making something would make someone else want to buy it from you. You can make all sorts of things that nobody wants to buy; the possibilities are endless, really. Balls of lint dusted with powdered sugar, broken ballpoint pens dipped in motor oil, burnt-out lightbulbs covered in melted Swiss cheese. It’s possible that someone might want to buy such bizarre items (call them “postmodernist found art” or something), but there clearly isn’t a large market for such goods, even if you should decide to manufacture thousands of them. Even in an aggregate sense, there’s also no particular reason to think that we can’t have an economy where millions of products pile up on shelves because no one can afford to buy them; indeed, that’s basically what happens in a recession.

In fact, the converse, “demand creates its own supply”, is considerably closer to true. It’s still not strictly true—centuries of searching for the elixir of immortality have failed to produce it, though modern genetic engineering just might finally succeed where all else has failed. (After all, every new technology is impossible… until it isn’t.) But in the long run, this converse law (it doesn’t have a name so far as I know) does contain an important grain of truth: If people want something badly enough, they will spend enormous resources in order to find a way to get it. If you know that a lot of people want something that no one is supplying, it behooves you to find a way to provide it—it might just make you a billionaire. Over centuries of technological advancement, humanity has found ways to provide many goods and services that were previously thought impossible, and one of the central benefits of a capitalist economy is that it provides powerful economic incentives for entrepreneurs to innovate and find ways to provide goods that people have always wanted but never had. Yet, even so, it isn’t true that demand creates its own supply—certainly not in the short run.

Neither supply or demand on its own does much of anything. You can have insatiable demand for something nobody can supply (the aforementioned elixir of immortality), and it still won’t be sold. You can have endless supply of something nobody demands (vacuum?), and it will remain worthless. It’s only when you have both supply and demand that a market becomes possible.

One of the central insights of modern economics is that prices and quantities in a capitalist market are determined simultaneously by supply and demand. In general, both supply and demand are constantly changing in response to events in the world, and thus the prices and quantities of goods shift from one equilibrium to another. In order to predict exactly how they will shift, we would need to know how both supply and demand have changed.

As Marshall alludes to in the above quotation, in some cases we can take either supply or demand as fixed and then the other one is what matters; but these are only special cases. In general, both supply and demand are subject to the winds of changing markets, and we need to keep track of both at once. If that sounds really difficult, that’s because it is—most of what economists do in the real world ultimately amounts to finding ways to distinguish supply effects from demand effects in various situations. Even most statistical methods in econometrics were basically designed as means of separating out demand-related causes from supply-related causes.

A lot of policy questions ultimately depend upon whether supply or demand is the dominant factor: If the business cycle is primarily driven by changes in demand, it makes sense to use monetary and fiscal policy to stabilize the economy (short version: it is, and it does). If it were instead driven by supply (“supply-side economics”), it would instead be better to make structural changes that reduce costs of production. (Why is this obviously wrong? Because there weren’t sudden increases in production costs in 2008—but there was a sudden collapse of consumer buying power. Maybe the 1973 recession can be explained by a sudden increase in oil prices, but there was no such supply shock in 2008.) If the labor market is primarily driven by demand, we need to find ways to get business to hire more people; but if it’s primarily driven by supply, we need to find ways to get people to get off their butts and try to find work. (Again, I think it’s pretty obvious that the former is true, not the latter—since at least 2000 there have never been as many job openings in the US as there were unemployed people.)

In the above policy questions the liberal view is the demand-side and the conservative view is the supply-side, but that need not be the case. Regarding renewable energy, for example, the more liberal view is that lots of people would want to buy electric cars and solar panels, if they were made available, but they aren’t—we are supply-constrained. The more conservative view is that the reason they aren’t selling more is that nobody particularly wants them and trying to force them on us is a fool’s errand—we are demand-constrained. Likewise when it comes to banking, liberals generally think that the reason there isn’t more credit is that banks refuse to supply loans, while conservatives (particularly from the banks themselves) usually argue that it’s because people aren’t willing to take the risk of taking out more loans.

The point, however, is that a lot of policy debates ultimately hinge upon the question of whether demand or supply is more important in driving a particular market—and since sometimes they are both important, sometimes the policy solution requires a combination of different approaches. One of the advantages of quantitative economic analysis is that we can determine exactly how much the costs and benefits of each policy option will be, and thereby choose the one that is most cost-effective.

In this way, “supply or demand?” is a lot like “nature or nurture?”; the answer is always “both”, but there are times when one factor or the other is more important for the policy question at hand.
