>As anarchist organizer (insofar as this is not an oxymoron)
It's not really an oxymoron at all. From the anarchist FAQ <http://www.infoshop.org/faq/secA2.html#seca23>:
A.2.3 Are anarchists in favour of organisation?
Yes. Without association, a truly human life is impossible. Liberty cannot exist without society and organisation. As George Barrett, in Objections to Anarchism, points out:
"[t]o get the full meaning out of life we must co-operate, and to co-operate we must make agreements with our fellow-men. But to suppose that such agreements mean a limitation of freedom is surely an absurdity; on the contrary, they are the exercise of our freedom.
"If we are going to invent a dogma that to make agreements is to damage freedom, then at once freedom becomes tyrannical, for it forbids men to take the most ordinary everyday pleasures. For example, I cannot go for a walk with my friend because it is against the principle of Liberty that I should agree to be at a certain place at a certain time to meet him. I cannot in the least extend my own power beyond myself, because to do so I must co-operate with someone else, and co-operation implies an agreement, and that is against Liberty. It will be seen at once that this argument is absurd. I do not limit my liberty, but simply exercise it, when I agree with my friend to go for a walk."
As far as organisation goes, anarchists think that "far from creating authority, [it] is the only cure for it and the only means whereby each of us will get used to taking an active and conscious part in collective work, and cease being passive instruments in the hands of leaders." [Errico Malatesta, Life and Ideas, p. 86]
The fact that anarchists are in favour of organisation may seem strange at first, but this is because we live in a society in which virtually all forms of organisation are authoritarian, making them appear to be the only kind possible. What is usually not recognised is that this mode of organisation is historically conditioned, arising within a specific kind of society -- one whose motive principles are domination and exploitation. According to archaeologists and anthropologists, this kind of society has only existed for about 5,000 years, having appeared with the first primitive states based on conquest and slavery, in which the labour of slaves created a surplus which supported a ruling class.
Prior to that time, for hundreds of thousands of years, human and proto-human societies were what Murray Bookchin calls "organic," that is, based on co-operative forms of economic activity involving mutual aid, free access to productive resources, and a sharing of the products of communal labour according to need. Although such societies probably had status rankings based on age, there were no hierarchies in the sense of institutionalised dominance-subordination relations enforced by coercive sanctions and resulting in class-stratification involving the economic exploitation of one class by another (see Murray Bookchin, The Ecology of Freedom).
It must be emphasised, however, that anarchists do not advocate going "back to the Stone Age." We merely note that since the hierarchical-authoritarian mode of organisation is a relatively recent development in the course of human social evolution, there is no reason to suppose that it is somehow "fated" to be permanent. We do not think that human beings are genetically "programmed" for authoritarian, competitive, and aggressive behaviour, as there is no credible evidence to support this claim. On the contrary, such behaviour is socially conditioned, or learned, and as such, can be unlearned (see Ashley Montagu, The Nature of Human Aggression). We are not fatalists or genetic determinists, but believe in free will, which means that people can change the way they do things, including the way they organise society.
And there is no doubt that society needs to be better organised, because presently most of its wealth -- which is produced by the majority -- and power gets distributed to a small, elite minority at the top of the social pyramid, causing deprivation and suffering for the rest, particularly for those at the bottom. Yet because this elite controls the means of coercion through its control of the state (see section B.2.3), it is able to suppress the majority and ignore its suffering -- a phenomenon that occurs on a smaller scale within all hierarchies. Little wonder, then, that people within authoritarian and centralised structures come to hate them as a denial of their freedom.
