Who Is a Moral Agent?

There is an important assumption about moral agency which always goes unstated in political discussion. It is this: institutions have moral agency. I could not possibly disagree with anything more than this. I believe that this assumption is responsible for a great deal of the evil that happens in the world. The assumption is unquestioned and unacknowledged because people do not think carefully about where moral agency can rest. Liberals who are outraged by the Citizens United verdict have no problems with treating the government as a valid moral agent, capable of killing, stealing, and taking on social projects. Likewise, right-wingers want to treat huge, fascistic corporations as equivalent to human beings, but balk at the idea of the government doing anything which doesn't put money into their wallets.

My take on this matter is simple: moral agency must lie with individual human beings. This is a minimal assumption, and I will take it for granted. However, humans do not live in isolation, and collective decisions must be made. As such, there must be some provision for super-individual moral agency. This is what I refer to as a group of individuals, or simply group. I do not use this term in a simple way, meaning any attempt at decision making involving more than one person. Instead, I use it in a technical way, to mean a voluntary association of individuals, none of whom relinquish or subvert their own moral agency, but merely use some method to determine the prevailing moral judgement of the group. The methods by which a group can come to such a determination are manifold: voting, by simple or super majority; formal debate; consensus building; and many not yet invented, I'm sure.

I contrast the idea of the group to the idea of the institution. An institution is also a super-individual decision-making body. However, it is not composed of individuals. In fact (as I shall discuss in a future post) institutions have priorities and prerogatives completely independent of the will of any given person. Obviously, decisions within institutions are ultimately made by individuals. But that individual must be willing to act, and must in fact act, in the interests of the institution rather than in their own individual interest or they would not be placed in such a position to begin with. A perfect example of this comes from a friend of mine who was tasked to go to a State Legislature meeting on behalf of the healthcare non-profit he works for. The people in charge had decided they would side with a certain political bloc which my friend opposed. However, it was his job to go and relay, and argue for, the position of the non-profit. His individual opinion of the matter at hand did not matter in the slightest. All that mattered was whether or not he could accurately relay the prevailing opinion of the institution he was a part of.

I do not think that the suppression of one's own moral agency in such a circumstance is conscionable. Be it as an employee, a soldier, or a politician, one should not have to abnegate one's own moral agency to serve a greater good. Such a good can be served voluntarily, and morally, by acting as part of a group of individuals, whose decision you can protest and even reject with no artificially contrived consequences to you, such as destitution or imprisonment.

My Solution to the Fermi Paradox

I think that the most likely solution to the Fermi Paradox is that, while life is exceedingly common in the universe, intelligent life is incredibly rare. In the four and a half billion year lifespan of this planet, life has existed on it from almost the very first moments. However, not until the Cambrian explosion about 530 million years ago did complex multicellular life exist. That means that for nearly four billion years, and starting from nine billion years after the birth of the universe, Earth contained nothing but single-celled organisms and colonies of such. And it is not until about 2 million years ago, 0.04% of the history of life on Earth, that the first technological intelligence emerged. And even that was simply monkeys hitting rocks against each other in a clever way! Anything more complicated than a stone arrowhead was invented in the last ten thousand years!

And let's look at how unlikely it is that humans (or any other hominid) ever even achieved technology. We had access to wheat, barley, and rice, easily domesticable plants that produced high yields and had good nutritional content. We had access to large animals with very particular internal dominance hierarchies which were not so recently evolved alongside us to attack us on sight, but not so distantly separate from us to be completely unwary at the sight of hunters with spears. (Here by "we" I am referring to any subset of humans who had such access — Jared Diamond goes into great detail as to who in fact had access to what.) We had access to workable stone, copious woodlands, and various ore deposits. We had an abundance of fresh water on a planet with an atmosphere suitable for lighting fires. Our luck in the development of our culture and eventual civilization was astounding. We were never subject to an extinction-level impact or eruption (although it seems that we came damn close).

I think that such luck is not only astounding, but is in fact astronomical. While life seems to have no trouble at all finding a place on a planet like the Earth (and perhaps on many other types of planets as well), technological civilization seems like and absolutely ludicrously unlikely event. It has happened exactly once in four and a half billion years (for 0.0002% of that time), or in 530 million years in which complex life has existed on Earth (or 0.0019% of that time). So I would imagine that life is in fact very common in the universe, although almost exclusively in the form of single-celled creatures living on rocks and in oceans. Very, very, very rarely one would find a planet with some sort of multicellular life on it — simple plant-like creatures, or molds of some sort. And once in an unimaginably huge while, one might expect to find a planet where technologically intelligent life once existed. Finding a planet where technologically intelligent life exists concurrently with us seems depressingly close to a fantasy.

Two Types of Free Will, part 3

As my previous post argued, the position that free will is somehow essentially true in a naive sense suffers from the problem highlighted in this Dilbert cartoon. It is an incoherent and meaningless way of talking about free will. However, it seems obvious (to me, at least) that there is some sort of free will at play. Otherwise, why would we even have such a concept? If we were mere automata carrying out our inherent programming, why would be have any reason to think about such a thing as free will? Hence, there is free will in some sense, or what I defined as phenomenological free will.

The description of phenomenological free will I gave in my first post on the subject relied heavily on the concept of consciousness, and I think it is exactly consciousness that makes free will a valid concept. As I will go to some length to describe in a future post, consciousness is the self-reflective model of the world we use to predict the future, including the future of our own mental states. It is also the tool by which we invent a narrative for the events that go on around us, sometimes referred to as confabulation. We instantly and instinctively come up with stories about our actions, thoughts, motivations and surrounding, often with absolutely no relation to truth or reality. Many cognitive fallacies are driven by the storytelling ability, such as the fundamental attribution error. We prefer reasons to be narrative than empirical. We need to know why things happen, not just that they do, even (especially?) if the why doesn't exist or is completely made up.

This exact ability applies as much to ourselves as to other people or objects. We come home from a long day at work and yell at our significant other over some petty transgression, and rationalize it by saying that they were annoying and we were tired and it's not our fault anyway. Every non-philosopher has said to themselves that they never intended to yell, and apologized afterwards. However, I contend that that impulse to deny volition isn't a mere face-saving exercise, but is rather precisely correct. We yelled completely automatically, because that is what our brain decided was the correct behavioural response to the situation. Our confabulation ability, however, even as it watched us yelling, was coming up with retroactive reasons to start yelling, and since we became consciously aware of yelling at the same time as we became conscious of our confabulation (since the confabulation is, in a very important sense, our consciousness) we go on to believe that we chose to yell of our own free will.

If we were less tired when we came home from work, our conscious mind might have been quick enough to notice that we were getting ready to yell, and would have stopped us doing so. That, it seems,  is another function of consciousness (although, of course, not exclusively of consciousness). Consciousness allows us — if we have time — to stop an action we notice we are about to start. When you reach for a hot skillet while cooking, you don't stop reaching (and thereby prevent burning your hand) until you actually look over and become aware of what you are about to do. Most telling of all, sometimes your don't stop reaching! You helplessly watch yourself proceed to grasp the burning hot skillet and burn your hand! Where is your free will then? This is a case of your brain going about the work it knows it needs to do, completely outside your conscious control, and your consciousness not working fast enough to stop it making a grave (and painful) mistake.

I won't delve into what "we" and "chose" refer to in the above paragraph (as those are both profound questions in their own right), but on the assumption that whatever it is that we refer to when we say "I" is a subset of the function of our brain, we can say that "we" are capable of contributing some influence on our actions, but that for the most part our brain goes about it's business completely without "us", until some sort of conscious decision needs to be made — perhaps one too complicated for our animal brain to figure out on its own. However, we should not despair! After all, "our" interests are almost always in line with that of our brain and body. So the limited, phenomenological sense in which we have free will is enough, even if it's a confabulation. For myself, I'm willing to trust my brain to take care of itself, and it's passenger, "me".

Two Types of Free Will, part 2

Previously, I set out two distinct phenomena which could be referred to as "free will". I here continue to contrast them, and attempt to show why one must be the case, while the other cannot be.

Phenomenological free will, I contend, is obvious, self-apparent, and completely, empirically true. It is very hard to find someone who will argue that they do not choose their own actions on a daily basis. It requires extremes of brain-altering drugs and abusive behavior to get someone to lose the sense that they are in control of their actions (note, however, that it is in fact possible to do so). The impression I get is that when most people hear someone argue that there is no such thing as free will, they think that the argument addresses phenomenological free will. And, of course, if this were the case, then arguing against free will would be lunacy. It's just that, as with the term "consciousness", no one bothers defining what they mean, so people end up talking at cross-purposes.

The very idea of metaphysical free will, on the other hand, suffers from incoherence in a non-magical universe. If there isn't a soul or spirit pushing and pulling the cords in our pineal glands, then where does this locus of decision reside? One cannot simply say "the brain", because the brain is a monstrously complicated system, segmented into an even more monstrously complicated collection of subsets, down to the connections between individual neurons, each portion of which considers input from sense organs, bodily nerves, and other portions of the brain. There is no "place" where a decision is made. The brain works as a whole system directing action, and conscious awareness of such decision-making is limited and after the fact.

At any level of description — physical, chemical, interneuronal, conscious — what happens in the brain is either completely random or theoretically predictable. Quantum effects do occasionally tip the scale and something weird happens, but unless you posit that that random weirdness is magically motivated, it can in no way be said to be willful. The interactions between neurons are far less random, and can be described and calculated fairly accurately, and interconnected systems of neurons can be isolated by structure and function. So, again, there is nowhere for this metaphysical decision maker to reside.

From a psychological perspective, the case is even more dire! You do what you are inclined to want to do. You take that action which the sum of your habits and motivations does in fact motivate you to take. If you chose to go running instead of eating that tub of ice cream, it's not because you are a free agent in a libertarian universe capable of making any logically possible action. Rather, your sense of guilt over not exercising recently, your motivation to look and feel better, and your desire to be healthier as you get older overcame your desire to eat delicious ice cream and feel aesthetic pleasure for a few minutes. You had these various motivations wrestling inside you, and your brain finally computed that the former motivations were more pressing than the latter, and sent the balance of these desires to conscious awareness so that you could write your "decision" to go running into your conscious narrative.

If you try to explain metaphysical free will from a psychological perspective, you get hopelessly muddled (I can't even formulate a coherent argument for such a thing in my mind), and the only fall-back I can see is on Descartian magic — souls and spirits and such.

Libertarianism (in the philosophical sense mentioned in the previous post) suffers from exactly the same problem as metaphysical free will. What would it even mean to say that the universe "could have gone a different way"? A quantum event could have had some other outcome than it did? Well, sure, in a counterfactual way. But since quantum events are truly random — that is, there is no way on principle to know which way they will come out — all you can possibly say is that it will take some value but you won't know what that value is until you actually measure it. So if there was in fact some metaphysical agent generating our wills in a libertarian universe, without magic powers its determination of a quantum outcome would happen simultaneously with its measurement of that outcome, so it would be beholden to that value no matter what. This is as bad as being beholden to a completely pre-determined outcome! It is worse, in fact, because in the quantum world you can't even make a prediction!

So, I dispose of libertarianism as hopeless. And I dispose of a metaphysical compatibilist view as meaningless at any level of analysis. Since this post is already almost twice as long as I expected it to be, I will hold off on my argument about phenomenological free will, and of my opinion on the nature of our will, until the next post.

Two Types of Free Will, part 1

I recently heard Daniel Dennett's explanation of his concept of deepity. It struck me that the concept of free will is exactly such a thing. It is a concept which is trivially true, but, in another sense, is logically ill-formed. The usual debate about free will is whether the concept of such is compatible with a deterministic (or truly random — that is, quantum) universe. Those who believe free will is compatible with a deterministic universe, and that therefore free will is "real" in some sense, are called compatibilists, while those who believe it is not, and that free will is an illusion, are called incompatibilists. The idea that the universe is not limited in this sense, but could in fact go some way other than the way it went is called libertarianism, but I more or less dismiss it out of hand as incoherent, for reasons I shall explain below.

Normally, free will is somehow taken to be a single, monolithic concept which is either true or false, and therefore is argued over. However, it struck me that there are two very different concepts of free will which no one bothers to distinguish (as far as I have seen). These I call phenomenological free will and metaphysical free will. Let us take them in turn.

Phenomenological free will is what we experience whenever we are awake and aware. It is the feeling of making choices, which is obvious and inescapable whenever we experience usual brain function, not under the influence of hypnosis, drugs or derangement of some sort. It is the conscious mind's narration of the things it sees us doing (we are consciously aware of our actions about 500 milliseconds after our brain initiates them). A large function of consciousness, it seems, is to inhibit actions it realizes aren't desirable, but it does not initiate them. Regardless, as far as one can tell (and in as far as there is a real "I" there to do the telling), we choose our actions and build our identities around those choices.

Metaphysical free will is what I call the idea of making "real" choices. That is, it is what explores the world of counterfactuals relative to what we did indeed choose, and decides that, had it wanted to, it could have selected one of those other choices. Alternately, it can be seen as that device which looks at the current state of the world, and picks what future actions would be most beneficial or desirable for the actor. It is, however, never forced to make any particular choice — it could make some wild, unmotivated flight of fancy at any moment (or at least, that must be a serious possibility in order for this style of free will to be worth considering). It is somehow independent of forces in this world, even if the actor himself isn't.

These two types of free will are very different to each other. One is a fact of experience and perception (hence, phenomenological), while the other makes a claim about the very nature of our minds, about what is true of the universe. I will contrast these two views in my next post, and show why one of these must be the case, while the other cannot be.

Paradox of Voting

The more people vote, the less chance each vote has of affecting the outcome of the election. This is called the Paradox of Voting. Some economists use this as a reason not to vote. I don't think it's a good reason not to vote (there are plenty of other good reasons not to vote). However, it is a good reason to not harass anyone about voting. The most common thing I hear from liberals and other supposedly civic-minded people when they learn that I don't vote is that it's awful and I don't get to complain about politicians.

First of all, it's not awful. Voting in a government election is a form of consent. Even those people who know that I'm an anarchist occasionally still entreat me to vote "because this is such an important election!" Well, uh, guess what? It's not. What's that? We need to replace the Big Oil and defense contractor-owned corporate stooge with a Big Bank and finance-owned corporate stooge? Why, yes, that is a meaningful Change which will bring Hope!

Second, voting isn't magic. Voting is just a method of collective decision making. There are others. I like consensus-building. It probably wouldn't work on a national level, but it produces far more meaningful results. When you tell me that you want me to go vote, you're not really saying you want me to vote. What you're saying is that you want me to agree with you on the value and legitimacy of the State government which you support at the moment. However, I do not support any such government, and I will not feel guilty for doing so. Give me a ballot with "None of the above" on it, and then I might go vote, because then voting would suddenly be a meaningful action again. It would not just be a choice of oppressors, as participation in any coercive institution is, but a form of expressing political will — in this case, the will to not have any of the jokers who call themselves politicians decide my economic and legal fate.

Finally, let's see what George Carlin has to say. I am a bit smug about coming up with that bit of wisdom before I ever saw this clip. The few times I have had the privilege of actually saying this to someone they end up grasping inarticulately at reasons why it's wrong before quickly ending the conversation. Alas, few people like talking about politics — or political theory, in any case. I look forward to donning my red and black "I DIDN'T VOTE" button this coming November. It generates just the right ratio of curiosity to contempt (I figure, if you're contemptuous to begin with, I'm not gonna get through to you in any case).

This concept has a sort of inverse corollary when it comes to consumption, which I will talk about in a future post.

Games

Most people have the intuition that, while you do not have the right to do violence to someone unprovoked, once they have done violence to you, you are justified in doing violence back to them. I have a system by which I try to schematize this intuition. I frame interactions between people as games. Such games have rules, which are agreed upon implicitly by those involved. The players in these games, I assume, are in an equal power relationship — that is, factors such as authority, gender and race are not involved (this mitigates such non-reciprocal cultural artifacts as orders and bigoted statements. [I should probably make a post about this assumption at some point.] ).

Cultural expectations and past relationships play big roles in determining the rules of such games. These rules can include: "talking is allowed", "intentional physical contact is not allowed" (this might well be a rule with strangers on the street), "kissing is allowed" (such as between people in a romantic relationship). For the vast majority of interactions, "don't do violence" is a rule. However, the rules of games can change, and often do in short order. These changes come about when one person implicitly or explicitly violates a standing rule. Once this happens, both players may now play by these new rules. What this creates in effect is an "eye for an eye" situation. If you are willing to violate one of the rules of the interaction, you are implicitly agreeing to play by that rule for the duration of the interaction. So, if you punch someone (a violation of a rule outside of a boxing ring), you agree to getting punched yourself. If you kiss someone, you are implying that they may kiss you back. And so on.

This allows us to set up a  naive code for behaviour: follow the rules, or, if you violate them, accept that the new rules your violation established apply to you as much as to anyone else you interact with.
