Vehicles: Experiments in Synthetic Psychology
Braitenberg's thought experiments in which simple sensorimotor machines produce lifelike behavior — a foundational text on emergence from minimal parts.

In a sequence of thought experiments, Braitenberg builds up imaginary “vehicles” from a few sensors, motors, and wires and shows how strikingly lifelike behavior — fear, aggression, love, foresight — emerges from arrangements that contain none of those things. It is a study in synthetic psychology: understanding by constructing, from the simplest coupling of perception to action upward.
The book argues that rich behavior is a property of organization — of coupling and feedback between simple parts — rather than of complex components; and that the way to understand such systems is to build them and watch what they do.
