 An important wrinkle for using this classification scheme in the history of philosophy is that it leaves out discussions of philosophical figures who did not focus their efforts on understanding whether innate knowledge is possible or even fruitful to have. Philosophy in the early modern period, in particular, is a lot richer than this artificial, simplifying distinction makes it sound. There is no clear way of grouping Hobbes with either camp, let alone Elizabeth of Bohemia, Anne Conway, George Berkeley, Émilie du Châtelet, or Mary Shepherd. This distinction, initially applied by Kant, is responsible for giving us a very restrictive philosophical canon, which does not take into account developments in the philosophy of emotions, philosophy of education, and even disputes in areas of philosophy considered more mainstream, like ethics and aesthetics.
