Physics and Philosophy

Until fairly recently, if you wanted to learn what humankind knew about:
The ultimate building blocks of the universe, you asked a metaphysician, especially one focused on ontology, the study of being. Now you ask a particle physicist.
The origins of the universe, you asked a theologian. Now you ask an astrophysicist.
The limits of human knowledge, you asked an epistemologist. Now you ask a neurologist, or perhaps an extremely specialized psychologist.
I don’t regret have reading Aristotle, Descartes, Hume, and the like, but the relevance of these folks’ thoughts on the summits of human knowledge has taken a significant tumble since they were in their heyday.
