Kant was interested in earthquakes not only because of the singular event in Portugal, but also for the reason he wrote on winds, the Theory of Winds (1756), and the West-Wind essay (1757). The most dramatic human encounters with natural forces are fire, storms, and earthquakes. Anyone intrigued by force would want to study these phenomena. Fire is pure energy. Earthquakes are the brutal action of force. And winds are the best examples of force moving through space. Meteorological phenomena in particular were an opportunity to apply the hypothesis of the force-space bond, the idea that active, dynamic forces modify each other and that external modifications of a radiation will affect the internal constitution of them. Air masses can be modeled as these fluctuations, and weather involves a clear instantiation of dynamic interactivity.
