In fact, Kant caught up with modern physics in several regards. Another of his insights is so basic that it is easy to miss. He defended force as the interactive matrix of nature and insisted on the importance of dynamics. The dynamic ontology of the Living Forces was ridiculed in its day, for Newton’s mechanics had digested Kepler’s celestial dynamics and marginalized Leibniz’s physical dynamics. Yet Kant’s stance would mark out the future course of science. We do not regard nature as a collection of particles and forces in empty space anymore, but instead as a system of energy-pulses interacting in fields. Dynamics has turned out to be fundamental.
