Bharath Vallabha has a post here about philosophical traditions, cosmopolitanism, and universality.
“The power of philosophy is that, by raising abstract questions about human beings, it generates inquiry to which any person can contribute, irrespective of their local, contingent situation. Universality is intrinsic to philosophy, and most philosophy classes in the Anglo-American tradition are taught with this aim of universality firmly in mind. How can ignorance of non-Western philosophy be compatible with this universal impulse of philosophy? How can Anglo-American philosophers claim to seek universal philosophical truths and concede that they are only aware of the Western philosophical tradition?”
“If most Anglo-American philosophers have “no opinion at all about non-Western philosophy because they are simply ignorant of it,” then in what sense can they speak about philosophy itself, rather than just about Western philosophy?”
“So why are most Anglo-American philosophers content to just continue the debates they inherited from their teachers, who inherited them from their teachers, and so on? Park articulated the urgent need to bring Western and non-Western philosophers into dialogue. Where is the urgency to do that on the part of most Anglo-American philosophers, not for the sake of minorities, but for the sake of their own growth as philosophers and world citizens?”
“According to Leiter, minorities should go beyond their traditions and engage with Western philosophy, but the only thing Western philosophers have to do is to continue on with the internal momentum of Western philosophy. In fact, they must guard it from being corrupted by the “consumer demands” of minorities.”
“It is understandable that Descartes and Kant in the 17th and 18th centuries did not engage with non-Western philosophy; after all, they wrote within a culture of colonialism. But what is the excuse for contemporary Anglo-American philosophers? Especially now that advances in civil rights, immigration, and technology have made our society more open than ever? Enlightenment philosophers stood ahead of their culture, prodding their contemporaries to look beyond their local traditions to a global world.
Contemporary Anglo-American philosophers, however, are lagging behind their culture, even as our global society hungers for new ideas.”
