Consciousness is not the product of a special network that enables all of our mental events to be conscious. Instead, each mental event is managed by brain modules that possess the capacity to make us conscious of the results of their processing. The results bubble up from various modules like bubbles in a boiling pot of water. Bubble after bubble, each the end result of a module’s or a group of modules’ processing, pops up and bursts forth for a moment, only to be replaced by others in a constant dynamic motion. Those single bursts of processing parade one after another, seamlessly linked by time. (This metaphor is limited to bubbles roiling up at a rate of twelve frames a second or faster; or consider a cartoon flip book, where the faster we snap the pages, the more continuous the movements of the characters appear.)
