Dennet said that our mind evolution got a big advantage in distributing content outside our hardware, freeing resources in favor to more abstract thinking as opposed to sheer fact recording. I strongly believe it, just look at how I'm clumpsy without intellisense. However, it is true that I need to hold a number of facts in mind at the same time, if I want to consider all the implications and draw the correct conclusions. When I'm in good shape, or the problem is of handy size, the balance between the two approaches is completely automatic: there are times, however, in which following an heuristic yelds to more productive results. Let's try.
