Is Philosophy Breeding Descartes and Spinoza Scholars?

ht imean, one great example is nich's genealogical method. He says philosophy should be breeding descartes and spinozas rather than scholars. What do we mean by historicism? We're all familiar with criticisms of the genealogicalmethod. It's like an adhominum fallacy, right? Just because morality is based in risantama doesn't mean that it's not also something that could be true.
