This essay discusses how, for Hegel, freedom can be realized in nature in a rudimentary fashion in solar systems. This solves a problem in Kant’s account of freedom, namely, the problem that Kant only gives a negative argument for why freedom is not impossible but does not give a positive account of how freedom is real. I give a novel account of Kant’s negative argument. Then, I show how, according to Hegel, solar systems can be considered as exhibiting freedom in (...) a rudimentary fashion. Finally, I lay out how Hegel systematically develops this point about the freedom of solar systems in the ‘Mechanism’-chapter of the Science of Logic. In doing so, he uses Kant’s negative argument in a ‘purified’ form to arrive at an account of an ‘intimate token-type relation’ between the planets in a solar system and the law that governs their motion. The essay as a whole provides a concrete example of how Hegel is an inheritor and radicalizer of Kant, both with respect to freedom’s reality and with respect to philosophical method. (shrink)
