In an earlier essay
I proposed a moral principle, namely, that the interests of memes (or ideas) can form a rational basis for morality whose results coincide well with our intuitions. In this essay, in response to some welcome prodding from occasional Ramblings contributor Don Geddis, I want to explore and expand on this idea.
Let me start by restating the problem I am trying to address: humans have a moral intuition
produced by Darwinian evolution in response to the fact that life is a game in the game-theoretical sense. Evolution optimizes for the survival of replicators. Humans are hosts for two kinds of replicators: genes, which are encoded in DNA, and memes, which were encoded originally in human brains and then in various artifacts: clay tablets, papyrus scrolls, and now digital media. Our genes and our memes have a mostly symbiotic relationship: our genes build brains capable of hosting memes, and our memes in turn invent things like agriculture and antibiotics, which in turn help to propagate our genes. But occasionally the interests of genes and memes are in conflict, such as when our memes invent birth control or weapons of mass destruction.
One particularly interesting side-effect of the invention of brains capable of hosting memes is the development of self-awareness and consciousness. Because we are conscious, we tend to assign a great deal of importance to consciousness, even going so far as to postulate that the fact that we are conscious is evidence of some sort of transcendent connection with the divine
. Even non-religious people put a lot of stock in consciousness. For example, the comment that Don made that inspired this essay was:
[M]y genes want my body to die, but I choose not to adopt those same goals, on my individual level. My intuition suggests that there should be similar conflicts with memes. Things that memes "want", which I may choose (on an individual level), not to adopt as my own personal goals.
Note the phraseology: "my individual level" and "my own personal goals" as distinct from the goals of both one's genes and memes. This assumes that there is an entity that is distinct
from one's genes and
memes but is nonetheless an actor
in the drama of life. This hypothetical entity is often called the soul, but the modern fashion is to eschew dualism and call it the mind
or the self
Much ink has been spilled on the question of whether or not this entity exists, and if it does, whether it is actually a player on the universal stage
. But to talk about morality at all
make this assumption. The questions of moral behavior are, by definition
, the questions of how to resolve conflicts between the desires of the self and the (possible) interests of other entities in the universe. Moreover, in order to have even the prospect of resolving such a conflict one must assume that there is some sort of moral agency
at work. If we don't have free will then there is nothing to decide and hence nothing to discuss. I am not taking a position over whether or not free will is actually metaphysically real. All I'm saying is that in order to talk about morality at all you have to take free will as a working assumption, even if it turns out that the ultimate truth is that free will is an illusion.
The problem, then, is this: there is a part of our brain that produces the sensation of consciousness, rationality, and moral agency, and we wish to elucidate a principle by which the activities of this part of ourselves ought to be conducted. Furthermore, we wish this principle to have the following properties: first and foremost, we want it to be useful
, by which I simply mean that it should not be vacuous, not that it should score highly according to some quality metric. Indeed, that would simply beg the question. The whole point of this exercise is to describe a quality metric by which to measure moral decisions. Second, the principle should be consistent with what is known about the nature of the universe. And third, to the extent possible it should be consistent with our moral intuition. Note that this property can never be fully met because there is a great deal of variation among people's moral intuitions (which is to be expected given that it is the product of Darwinian evolution). Indeed, much of what I am proposing here hangs on the meaning of the word "our" in the phrase "our moral intuition."
All the moral systems that I know of fail to exhibit one or more of these properties. For example, the ethical culture movement
is based on the idea that one should live according to "ethical principles". But this is vacuous, and hence not useful: it simply replaces the word "moral" with the word "ethical", which gets us exactly nowhere. Moral relativism is, likewise, vacuous and hence unacceptable. Religions based on divine revelation are not vacuous, but they fail on the second count: they are not consistent with what we know about how the universe really is. Humanism is neither vacuous nor inconsistent with science, but it fails because it is not consistent with intuition. It is species-ist, placing the interests of humans axiomatically above the interests of all non-human entities, which most people find unacceptable once they actually pause to reflect on what this actually entails
It is worth digressing for a bit to talk about Sam Harris's moral premise as described in his book The Moral Landscape
. Sam's position is that, "morality is that which advances the interests of conscious beings," a premise that I actually do accept (but as a constraint, not a definition). The problem is that Sam's elucidation shows that what he really means by "conscious beings" is "Western liberal intellectual members of academia who think like Sam Harris." In particular, religious people somehow abdicate their claim to being conscious merely by virtue of being religious. This is the fundamental problem with any humanistic premise: like it or not, religious people, even religious fundamentalists, are still human, still conscious beings. There is no principled way to start with "the interests of conscious beings" as your premise and not accept the possibility that standing on the street corner screaming "God hates fags" might be moral.
So what I propose instead as a moral premise is: moral behavior is that which advances the interests of memes.
Before I go into a detailed analysis, let me point out that this is still a humanistic worldview. The difference between humanism and meme-ism (actually, I think a better name might be idea-ism) is that idea-ism is humanistic as a consequence
rather than a premise. In the current state of the world, memes can only survive in human brains and artifacts. Accordingly, humans have value, not axiomatically, but because they provide -- and produce -- habitat for memes. Notice that this provides a principled
way to resolve some very thorny dilemmas for the axiomatic humanist. For example, as Bertrand Russell famously lamented:
I cannot see how to refute the arguments for the subjectivity of ethical values, but I find myself incapable of believing that all that is wrong with wanton cruelty is that I don’t like it.
On the idea-istic view, wanton cruelty is wrong because it destroys habitat for memes. Likewise, it is immoral to (say) withhold education from women because education is a prime conduit for the replication of memes. Withholding education is tantamount to forced sterilization with respect to the interests of memes. (So is censorship.)
So let us evaluate this proposal with respect to my three criteria. It's pretty evident that idea-ism is non-vacuous. The mere fact that someone could potentially disagree with it is proof of that. Likewise, it is consistent with science. But is it consistent with intuition?
As mentioned earlier, no moral principle can ever be consistent with everyone's moral intuition. That's actually a feature: any principle consistent with every human's moral intuition would be tantamount to moral relativism and hence vacuous. And most people really do want to be able to distance themselves from the more distasteful behaviors exhibited by members of their own species
. So the consequences of idea-ism are likely to conflict with the moral intuitions of fundamentalists. That is not in and of itself a failure.
Of course, idea-ism is first and foremost consistent with my own moral intuitions, and, I believe, consistent with the moral intuitions of western liberal intellectuals, a group of which I am (not coincidentally) a member. But I think there's an argument to be made that idea-ism is not just a thinly disguised form of bigotry in favor of my own kind. Ideas are special in a way that national identity, skin color, and even species-identity are not. Ideas, and more fundamentally information
, is woven into the fabric of life at the very deepest levels. Life, at root, is the process of replicating information. That this information has been predominantly encoded in DNA is a detail. DNA just happened to be handy given the chemical inventory of this planet. but there's no reason to believe that life based on some other chemistry would be any less worthy. But once you've made this leap and stopped being a DNA-ist, it is not a big leap from there to the realization that there's nothing particularly special about chemistry. We are not that far away from having purely mechanical self-replicating systems
. Artificial intelligence is a bit further off, and artificial self-awareness probably further still, but there's no indication that these things are inherently impossible. If and when it happens why not have a set of future-proof moral principles handy?
But you don't have to delve into the realms of science fiction to find plausible intuitive justification for idea-ism. We are, in our present states, a symbiotic collection of both genes and memes. At the moment, neither can survive without the other. This basic fact of our present existence manifests itself in our yearning to connect with other meme-hosting entities. This desire goes beyond our need to gather in physical groups in order to survive. The exchange of memes is as fundamental to our nature as eating or sex. We tell stories. We engage in chitchat. We write blogs. As children we jump up and down and shout "look at me!" in the unconscious hope that something in our brain will escape and find a home in another.
And when we die, we want to be remembered.
All of these traits are fundamental to human nature. I will go further: these traits are what define
human nature. We are not our bodies, we are our minds. We can lose our arms and legs, our hearts, our lungs, even our ability to biologically reproduce and no one would question that we are still human. But if we lose our minds
we are dead, even our bodies are otherwise healthy.
Idea-ism is not an arbitrary premise. It is a recognition of our true nature. But more than that, it is a choice
to take that nature
and make it (or view it as) a purpose
and hence a guide for making decisions. Beyond being useful, rational, and intuitive, it's also noble
. It is an embrace of life in the broadest possible reading.
I hope you'll help me spread the Word.
