In a low-research day I had the great pleasure of participating in the "Colloquium" (like a research defense) for NYU Gallatin undergraduate Physics Major Daniel Seara, who did his research on philosophy and physics. The conversation was great; Seara understood some pretty damned difficult books, like Kant's Prolegomena and Hume's Treatise, neither of which I ever really grasped. For me the most interesting points included, for one, a discussion of the relationship of subjectivity to "flaws". Is human science subjective because humans are flawed? Or would it be subjective even if they were flawless reasoners? I think the subjectivity is pretty deep. For another, we discussed a bit why materialism (the belief in an external reality) was important to Marx and Lenin. Strange! Thanks and congratulations to Seara!
