"A psychological consequence of this is the following: when we analyze a mechanism we tend to over estimate its complexity."

“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 in such a way that ultimately the state of the world is a more favorable one.”

“A structure made up of fine threads, so many and so fine that even the strongest magnification of the microscope was hardly sufficient to allow all of them to be seen clearly. Some of the threads ran together in bundles and in layers in specific directions; others lay seemingly randomly distributed every which way through the tissue. Embedded in this felted mass of fibers, it was possible to discern spherical structures, the nuclei of the nerve cells...”

“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.”

“You may regret this, but you will soon notice that is a good idea to give chance a chance in the further creation of new brands of vehicles. This will make available a source of intelligence that is much more powerful than any engineering mind.”

“sketch a few facts about animal brains that have inspired some of the properties of our vehicles, and their behavior will then seem less gratuitous than it may have seemed up to this poin.t”

“It is actually impossible in theory to determine exactly what the hidden mechanism is without opening the box, since there are always many different mechanisms with identical behavior. Quite apart from this, analysis is more difficult than invention in the sense in which, generally, induction takes more time to perform than deduction: in induction one has to search for the way, whereas in deduction one follows a straightforward path.”
