Abstract
In this article ego states are seen to have their place in the current exciting convergence of views on the way the mind structures itself through the repetitive processing of incoming perceptions. As the receptors in the mind assimilate the similar and filter out the dissimilar, generalized representations of experience are built up and stored. It appears that this fundamental neural process builds up coherent networks of representations that function as wholes, interlinking with each other in increasing mental complexity. Ego states appear to be an evolved example of this impressively powerful process of structuration.
