World dynamics

In this review of Jay W. Forrester's World Dynamics¹, the first model of the whole world system is described and its potential assessed. The background notion is that the rational revolution, for the first time in mankind's evolution, depends on anticipatory action, not on mere reaction to crises. Computer modelling has a powerful potential of increasing our awareness in areas where human thinking fears to tread ; so that by dealing with a multitude of pressures that may destroy the world systems, world policies might be introduced designed to cope with the pressures simultaneously.
