I think that there is no literal field. Self-organization requires only a capacity to experience and effect change. When a car breaks down, there is no field of organization which is going to appear and fix it - the car is fixed by the sensory-motor capacities of the car's owner and nothing else. Someone discerns that the car is broken, cares that it is broken, and is able to invest that care into electrical changes into their own brain which direct a human body to interact with its world.
If you look at a person fixing their car from the outside, knowing nothing, you might conclude that there is a field which attracts a mechanic to the car being transmitted through the telephone or some such thing, but that is only a model of the situation in which subjectivity is not accounted for. If you believe in a universe where matter lacks the capacity to sense itself, then you have to compensate by imagining that space has magical properties, hence 'force' and 'field'. Voila - a universe of emptiness haunted by unexplained tendencies with scientific sounding names.
