Notes on Hume - A Treatise of Human Nature, I.I.II
An absolutely crucial aspect of Hume’s Treatise is the fact that, again, unlike Descartes and Hegel, the mind is not a “thing”: rather, it is a system. The mind is a an aggregate set consisting of perceptions and relations organized by principles. Thus, the question of process and becoming are absolutely crucial; being is pretty much always secondary. Concepts are best understood in terms of their mutual interrelation: as his criticism of Hume makes clear, this is something Kant was never really able to grasp.
