I haven’t found any interesting modern day philosophers. They might have some good arguments here and there but nothing in impact compared to some of the medieval or classical philosophers. The problems they are dealing with — e.g. science, language, society — are also very resistant to simple resolution. Then again, most of them are operating within the paradigm of materialism, and the dominating majority are influenced by left-wing political ideologies, which has become the war cry for equality, rather than explaining how differentiation emerges and becomes real.
