A Basic Review of Desirism

type="html">

I base my posts in this blog on a moral theory called desirism.

Desirism holds that malleable desires are the ultimate object of moral evaluation.

A malleable desire is good to the degree it tends to fulfill other desires and bad to the degree that it thwarts other desires.

The degree that a malleable desire tends to fulfill other desires is the degree to which people generally have a reason to use social forces such as praise, condemnation, reward, and punishment to promote that desire.

The degree that a malleable desire tends to thwart other desires is the degree to which others have reason to use these same social forces to inhibit that desire.

A right act is the act that a person with good desires would perform. A wrong act is the act that a person with good desires would not perform. A permissible act is one that a person with good desires may or may not perform depending on other considerations.

Perhaps the most useful account of how desirism works can be found in the post The Hateful Craig Problem, which looks at the problem of trying to make sure that Hateful Craig will not do harm even when there is a chance he can get away with it. That post demonstrates how the principles of desirism would be put to use.

A commenter, Drake Shelton, is providing me as an opportunity to use his comments about desire utilitarianism as a foil for explaining some of the details of the theory. I tend to find these useful because it allows me to answer the claims of a real person rather than an imagined critic.

I want to start with this:

This falls prey to the problems with Utilitarianism. On your own admission then, the execution and torture of the inferior race gives pleasure to the superior race therefore it is the right thing to do. This theory also caters to totalitarians systems. In utilitarianism, the individual must sacrifice his own interests for the interests of the whole or the state.

No.

This criticism applies to a related theory that can be properly called "desire fulfillment act utilitarianism". That theory says that the right act is the act that would fulfill the most and strongest desires. That theory requires the conclusion that if the torture of a young child fulfills more and stronger desires than it thwarts (by fulfilling the desires of 1000 sadists while thwarting the desires of 1 child) it would be the right thing to do.

However, desirism evaluates desires - and evaluates actions only in a derivative sense. A desire is good to the degree that it tends to fulfill other desires.

The sadist's desire is a desire that tends to thwart other desires. In fact, it inevitably does so. Therefore, the sadist's desire gets counted as a bad desire. It is a desire that people generally have many and strong reasons to inhibit through social forces such as condemnation and punishment. We have many and strong reasons not to want this desire around - and reasons to use our social forces to fight it, and to raise kindness and consideration in its place. Even sadists have many and strong reason to bring these social forces to bear to prevent sadism in others and to promote kindness in its place.

It doesn't matter how many sadists there are, it is still the fact that sadistic desires are desires that tend to thwart other desires. In fact, the more sadists there are, the more desire-twarting we can expect.

I go into this objection in greater detail in The 1000 Sadists Problem

Here's another objection:

Sounds much like psychological hedonism.

Well, it's not much of an objection, but I would like to use it to explain the difference between desirism and psycholoogical hedonism - a theory that was largely discredited 150 years ago but which is still popoular among many atheists.

Psychological hedonism holds that each of us only seeks two things - our own pleasure, and our own freedom from pain. Nothing else matters. Pretty sunsets, the health and well-being of our children, are all valued for no reason other than those are the means by which we can activate the pleasure centers in our own brain - or save ourselves from pain. We give to charity, we risk our lives to save others, we cry at funerals, because these are the tools we have for triggering the pleasure centers of our own brain.

Before I consider objections to this theory I would like to broaden the scope a bit for the sake of efficiency.

Psychological hedonism is an internal state theory. It holds that the only thing in the world that matters to an individual is having its brain in a particular brain state. Other internal state theories hold that happiness is the only thing that matters - or desire satisfaction.

Note: Desire satisfaction is not the same as desire fulfillment. Desire satisfaction is a feeling - much like pleasure or contentment - that one gets when one (thinks that) the world is going the way one wants it to go. Desire fulfillment, on the other hand, takes into consideration that a desire is a propositional attitude - it takes as its object a proposition P. (Thus, desires can be expressed in the form "agent desires that P") A "desire that P" is fulfilled in any state of affairs in which P is true. A desire that I am saving children from disease is fulfilled in any state of affairs in which the proposition "I am saving children from disease" is true.

I discuss internal state theories in detail in the post Internal State Theories.

Briefly, one of the major objections is that no internal state theory can handle the issue of the experience machine.

An experience machine is a machine that feeds electrical impulses into your brain that puts your brain in the state that the internal state theorist claims to be only thing that matters. Your brain is put in a jar, electrodes are hooked up into it, the electrodes produce the brain state of value and keeps it in that state.

Faced with this possibility, many people - most people - will claim that this is not what they want.

Desire fulfillment avoids the problem with the experience machine by holding that what matters to a person who desires that P is that P is made true. The desire to help protect children from disease can't be fulfilled by an experience machine. It can only be fulfilled by creating a state of affairs in which one is actually protecting children from disease.

Desirism is an external state theory. It holds that what a person with a desire that P seeks is (often) an external state - a state of affairs in which P is true - that will make the experience machine entirely unattractive.

There are other considerations to raise as well. For example, it is easier to tell a story of evolution whereby biological entities acquired at least some dispositions to change the world than it is to square evolution with the theory that they only acquire an interest in creating a particular brain state. Evolutionary success - procreation, for example - is an external state. External state changes are necessary for evolution.

Another post in which I draw distinctions between desirism and psychological hedonism (and other internal state theories) can be found in the post Egoism.

Oh, and I was accused in a comment against using a term in its own definition. That, in fact, is not the case. I illustrated a use of the term. Dictionaries, when defining a term, will often give an example of how the term would be used when it meets that definition. It helps to clarify the definition. The way that one might define the word "cow" by pointing to a cow.

Desirism and Neurobiology

type="html">

CNN has an article, Can a Molecule Make Us Moral?" that invites me to consider the relationship between desirism and neurobiology.

Simply put, the article reports that levels of oxytocin affects such things as whether an individual is trustworthy or generous.

Does desirism have a problem with that?

No.

The systems for morality are to be found in the brain. If desirism is correct, neuroscientists will discover that behavior is grounded on beliefs and desires, that desires are propositional attitudes, and that agents will act to fulfill the most and strongest of their current desires given their beliefs. It will discover that some desires are malleable, and that the mechanisms for change include reward and punishment. They will also learn the mechanisms for praise and condemnation and that they have the same effect as reward and punishment. All of these will have to do with electrochemical operations in the brain.

My greatest value from working with Luke Muehlhauser is that, unlike me, he had the time and the skill to look at current neuroscience in detail. We found a lot of correspondence between desirism and what neuroscientists were discovering about the brain.

For example, neurobiologists were able to look at the ways experience change an agent's long-term desires. Experience provides rewards and punishments - which have the affect of strengthening or weakening agents' desires.

We did not find a perfect fit.

I had been saying that rewards and punishments modify desires directly. The research seems to be suggesting that the learning effect springs from a difference between expected outcome and actual outcome. Expected rewards or punishments do not modify behavior. Though some of the later research we looked at suggested that current reward independent of expectation still has some role to play.

In developing desirism, I had claimed that the agent does not have to be the one rewarded or punishment for reward or punishment to have an effect on his moral character. The effect is generated by witnessing the reward or punishment - the praise or condemnation - of another person. This provides a role for public criticism and for public praise such as award ceremonies and other honors.

Neurobiologists tell us that we have mirror neurons. These cause us to experience the rewards and punishments of others as if they are our own - which is one of the mechanisms through which social forces mold our moral character.

Even works of fiction from religious parables to children's stories to Star Wars and Lord of the Rings to World of Warcraft and Grand Theft Auto shape our moral characters by making us a witness to the praise and condemnation - the reward and punishment - of others.

If oxytocin promotes generosity and tolerance, the next question to ask is how social forces such as praise and condemnation affect oxytocin.

I do have one long-standing objection to the way biologists approach the relationship between biology and morality. Biologists identify behavior as moral and look for the biological causes of that behavior. However, they gloss over the question, "What is it that makes this behavior moral?"

Higher oxytocin levels may end up being associated with opposition to capital punishment, for example. Does this answer the question of whether capital punishment is wrong? If so, how? How do you get from premises relating biological facts to attitudes about moral issues such as abortion, gay marriage, capital punishment, whether it is okay for 1% of the people to own 50% of the planet - to conclusions about whether these are, in fact, morally right or wrong?

One of the common links biologists draw is that if we are morally opposed to X, then it is wrong. It then looks for the biological underpinnings to our opposition to X and claims to be studying morality. However, this would imply that if we had a disposition to approve of killing all the Jews, then the Jews deserve to die. If we are disposed to enjoy having sex with our stepchildren, then it is morally permissible to do so. Nothing is right or wrong except insofar as a genetic accident makes it so. Alter our biology so that we can enslave others without moral regret, and slavery becomes morally permissible.

And what is the relationship between morality and social tools such as praise and condemnation about? If morality is grounded on some hard-coded biological fact, why praise or condemn others?

Desirism has an answer to the question of relating biology to morality that answers these questions. For moral virtue, we are looking for malleable desires that people have the most and strongest reasons to promote using social forces such as praise and condemnation. An agent may be biologically constituted such that he can kill the Jews without guilt, but this does not change the fact that people generally have many and strong reasons to promote an aversion to that kind of killing.

What makes aversion to such killings a virtue?

Well, people generally have many and strong reasons to promote an aversion to these types of killings using social tools such as praise and condemnation. And moral claims contain elements of praise and condemnation.

What more do you want?
