Because there are many possible political spectrums, one should not talk about _the_ political spectrum as if there were only one. At the very least, one should first establish context by defining the axis upon which different positions will be measured. Unfortunately, this is seldom done (see PoLitics, e.g.).
In a modern Islamic country, the political spectrum might be divided along the issue of the clergy's role in government. Those who believe clerics should have the power to enforce Islamic law are on one end of the spectrum, those who support a secular society are on the other.
In modern WesterN? countries, the spectrum is usually defined along an axis of ConservatisM? ("the right") versus SocialisM ("the left", called liberalism in the UnitedStates). There are different opinions about what is actually being measured along this axis. Some people view it as a measure of social equality, some as a measure of the government's role in the economy, some as a measure of religion's place in society, some as a measure of the different weight put on fair outcomes versus fair processes.
This right-left spectrum is so common that many people have a hard time conceptualizing any alternative to it (see PoLitics, e.g.). However, numerous alternatives exist, usually having been developed by people who feel their views are not fairly represented on the traditional right-left spectrum.
Such an alternative, and an example of a two-axes spectrum, has been popularized by the [Advocates for Self-Government]. One axis measures your views on "personal self-government", which pertains to the government's role in the home, church, and between consenting adults in private, while the other axis measures "economic self-government", which pertains to the government's role in economic activities. With two axes, there are four different extremes: Libertarian, which favors personal freedom and economic freedom; Left Liberal, which favors personal freedom but opposes economic freedom; Right Conservative, which favors economic freedom but opposes personal freedom; and Authoritarian, which opposes both personal freedom and economic freedom. There is, of course, plenty of room in the center for people who hold moderate views along either axis.
Another alternative currently popular among certain environmentalists uses a single axis to measure the good of the earth against the good of big business, which is seen as being the force most likely to harm the earth. On this axis, many mainstream politicians normally considered left-wing (such as BillClinton) are considered no different from those normally considered right-wing, because of their allegedly pro-business policies.
In 1998, political author VirginiaPostrel?, in her book TheFutureAndItsEnemies?, offered a new single axis spectrum that measures ones view of the future. On one extreme are those who allegedly fear the future and wish to control it. On the other hand are those who want the future to unfold naturally and without attempts to plan and control.
The other thing is that the particular diagram to which you refer is fairly non-discriminatory. Inasmuchas it can't distinguish between libertarianism and anarchism - one of which has policies much like capitalism, one of which has policies much like socialism - and again between fascism and marxism. In short, they have identified different ideologies by pinching the diagram off into a diamond, which is probably more for the purposes of popularizing libertarianism (something the site obviously tries to do) then accuracy. -- JoshuaGrosse
Economic self-government: the one that showed up as horizontal on the chart, of course. :)
The diagram can be represented like this:
++ +- -+ --
Oh...I see what they're doing. In that case the corners of the graph are grossly mislabeled - a completely totalitarian government is authoritarian whether or not they allow a free market. But all in all, it's the square is suggested, only tilted in a non-standard way. Usually left-right is portrayed as an economic spectrum. I'm very sorry for the confusion. I still say the source is biased, though. -- JoshuaGrosse
Just as libertarian is usually applied in a narrow sense to exclude libertarian socialists (~anarcho-syndicalists), it seems anarchism is usually applied in a narrow sense to exclude anarcho-capitalists (~free market libertarians). It's in this sense that I was using the term. Obviously anarcho-syndicalism has strong ties to socialism and free market libertarianism has strong ties to capitalism, but the two systems aren't distinguished on the diamond. A square or circle would be much better in terms of actually representing ideologies.
Other than those, though, I don't really have any complaints other than perhaps a slight editorial tone (fear the future and wish to control it). And, of course, none of this is meant as negative criticism, my being too uncertain to try writing political articles myself. :) -- JoshuaGrosse
