I'm not sure about the specifics of what iwwr is thinking, but basically I think he means that humans have the ability to create and pass on knowledge (state) from one generation to the next. Because each generation only has to build off of the knowledge of previous ones there is no set limit to how much humans as a whole can know. Technically, this ability isn't unique to humans alone. Other species, such as dolphins and chimpanzees, are also able to create and pass on knowledge. For example, certain dolphins around Florida have developed a strategy of catching fish by first encircling areas of water by kicked up sand: http://www.youtube.com/watch?v=ArsoMcVi5MM&feature=player_embedded http://www.youtube.com/watch?v=ArsoMcVi5MM&feature=playe... This is purely a learned behavior and has to be taught to offspring.
