The Stability of Three

One of the things I've always respected about Neal Stephenson is his attitude (or rather, the lack thereof) regarding politics:
Politics - These I avoid for the simple reason that artists often make fools of themselves, and begin to produce bad art, when they decide to get political. A novelist needs to be able to see the world through the eyes of just about anyone, including people who have this or that set of views on religion, politics, etc. By espousing one strong political view a novelist loses the power to do this. Anyone who has convinced himself, based on reading my work, that I hold this or that political view, is probably wrong. What is much more likely is that, for a while, I managed to get inside the head of a fictional character who held that view.
Having read and enjoyed several of his books, I think this attitude has served him well. In a recent interview in Reason magazine, Stephenson makes several interesting observations. The whole thing is great, and many people are interested in his comments regarding an American technology and science, but I found one other tidbit very interesting. Strictly speaking, it doesn't break with his attitude about politics, but it is somewhat political:
Speaking as an observer who has many friends with libertarian instincts, I would point out that terrorism is a much more formidable opponent of political liberty than government. Government acts almost as a recruiting station for libertarians. Anyone who pays taxes or has to fill out government paperwork develops libertarian impulses almost as a knee-jerk reaction. But terrorism acts as a recruiting station for statists. So it looks to me as though we are headed for a triangular system in which libertarians and statists and terrorists interact with each other in a way that I’m afraid might turn out to be quite stable.
I took particular note of what he describes as a "triangular system" because it's something I've seen before...

One of the primary goals of the American Constitutional Convention was to devise a system that would be resistant to tyranny. The founders were clearly aware of the damage that an unrestrained government could do, so they tried to design the new system in such a way that it wouldn't become tyrannical. Democratic institions like mandatory periodic voting and direct accountability to the people played a large part in this, but the founders also did some interesting structural work as well.

Taking their cue from the English Parliament's relationship with the King of England, the founders decided to create a legislative branch separate from the executive. This, in turn, placed the two governing bodies in competition. However, this isn't a very robust system. If one of the governing bodies becomes more powerful than the other, they can leverage their advantage to accrue more power, thus increasing the imbalance.

A two-way balance of power is unstable, but a three-way balance turns out to be very stable. If any one body becomes more powerful than the other two, the two usually can and will temporarily unite, and their combined power will still exceed the third. So the founders added a third governing body, an independent judiciary.

The result was a bizarre sort of stable oscillation of power between the three major branches of the federal government. Major shifts in power (such as wars) disturbed the system, but it always fell back to a preferred state of flux. This stable oscillation turns out to be one of the key elements of Chaos theory, and is referred to as a strange attractor. These "triangular systems" are particularly good at this, and there are many other examples...

Some argue that the Cold War stabilized considerably when China split from the Soviet Union. Once it became a three-way conflict, there was much less of a chance of unbalance (and as unbalance would have lead to nuclear war, this was obviously a good thing).

Steven Den Beste once noted this stabilizing power of three in the interim Iraqi constitution, where the Iraqis instituted a Presidency Council of 3 Presidents representing each of the 3 major factions in Iraq:
...those writing the Iraqi constitution also had to create a system acceptable to the three primary factions inside of Iraq. If they did not, the system would shake itself to pieces and there was a risk of Iraqi civil war.

The divisions within Iraq are very real. But this constitution takes advantage of the fact that there are three competing factions none of which really trusts the other. This constitution leverages that weakness, and makes it into a strength.
It should be interesting to see if that structure will be maintained in the new Iraqi constitution.

As for Stephenson's speculation that a triangular system consisting of libertarians, statists, and terrorists may develop, I'm not sure. They certainly seem to feed off one another in a way that would facilitate such a system, but I'm not positive it would work out that way, nor do I think it is particularly a desirable state to be in, all the more because it could be a very stable system due to its triangular structure. In any case, I thought it was an interesting observation and well worth considering...
