So, is your brain really hierarchic? I think it is. Here's the informal proof. Suppose I asked you where to find Q-Tips in your house. Where is the lighter fluid? Your Federal tax return for 1998. If you're like me and many other people, each of these things has a "place" where they belong. Where I live, the Q-Tips are in the medicine cabinet in the bathroom off the master bedroom. The lighter fluid is outside next to the briquettes under the overhang by the patio. The tax returns are in the cabinet under the bookshelves in the den. Now think about your whole house, and how many things there are in it, and for almost every thing in your house there's an equivalent place in your brain where you store knowledge of how to retrieve the object. That's a hierarchy. A house is divided into inside and outside, inside is divided into rooms, rooms into fixtures, and then the fixtures break down into compartments with different names depending on whether it's a refrigerator, book case, medicine cabinet, etc. Now of course there are non-hierarchic links, that accounts for serendipity or daydreaming, but when you want to get a job done, hierarchies do the hard work of organizing for quick retrieval.
