Philosophers, notably Popper, have also considered the relation between subjective knowledge (which he calls world 2), objective knowledge (world 1) and the knowledge represented by man-made artifacts (world 3).

and talk about extelligence space. There is a total phase space (intelligence space) for the human race, which consists of everything that can be known and represented. Within this there is a smaller set of what is known at any given time. Cohen and Stewart propose the idea that each individual can access the parts of the extelligence space with which their intelligence is complicit. In other words, there has to be, at some level, an appreciation of what is out there and what it means. Much of this 'appreciation' falls into the category of
