  When it comes to explaining how individual specious presents combine to form streams of consciousness, a simple and perspicuous solution is available to the Extensional theorist: perhaps a stream of consciousness is nothing more than a succession of specious presents laid end-to-end in the manner of a line of building blocks, or bricks in a wall, in the manner depicted in Figure 7 below. Here just a short stretch of a stream of consciousness is depicted, consisting of just two adjacent specious presents, SP1 and SP2, but the same experiential structure could easily extend over longer periods.
