 abstract={This paper notes that the evolution of civilizations according to AJ. Toynbee can be explained by a simple feedback model that may be used as a stimulating "tool for thought". Even if the forward path simply consists of an integrator and the feedback path of a pure delay element, the model gives rise to a variety of responses, thus demonstrating clearly the counterintuitive behavior of closed-loop systems. The relation of the model with those used in control system design is pointed out.},
