It is actually impossible in theory to determine exactly what the hidden mechanism is without opening the box, since there are always many different … - Valentino Braitenberg

The brain is encased in the head, the part of the body which in most walking, flying or swimming animals is the leading end of the moving body (with few exceptions: starfish, cuttlefish, humans, penguins when they are not swimming). The obvious risks which this localization entails are apparently compensated by the advantage of direct short connections with the sense organs localized in or on top of the head (olfaction, taste, vision, audition, vestibular sense), which together with the brain could be seen as something like the cockpit of the animal, or the pilot if one prefers.

Ad Aertsen succeeds in allowing his sense of humour to shine through the deep seriousness of his scientific ethos. He also has a very balanced attitude to the question of "theory or experiment".

Not it is different with type 14 vehicles. They move through their world with consistent determination, always clearly after something that very often we cannot guess at the outset - something that may not even be there when the vehicle reaches the place it wants to get to. But it seems to be a good strategy, this running after a dream. Most of the time the chain of optimistic predicitions that seems to guide the vehicles's behaviour proves to be correct, and Vehicle 14 achieves goals that Vehicle 13 and its predecessors "couldn't not even dream of." The point is that while the vehicle goes through its optimistic predicitions, the succession of internal states implies movements and actions of the vehicle itself. While dreaming and sleepwalking, the vehicle transforms the world (and its own position in the world) in such a way that ultimately the state of the world is a more favorable one.
