Affect may be predominantly ego generated and centred or somatic in origin and unfolding. As far as the ego is concerned, although negative affect may be unboundedly intense, positive affect, although very much socially promoted is bounded and relatively weak. Its limits are the limits of the ego's reversion into itself and these are surprisingly narrow, much more so than how they present themselves - but isn't that the very nature of the ego. Somatic negative affect can be extremely intense but is bounded in that beyond a certain point one loses consciousness. Somatic positive affect is however unbounded, but rarely encountered in its extreme forms - and these tend to be feared more than desired, with a fear that can be easily overcome.
