Where in the brain are the neural correlates of perceptual consciousness?  Some leading theories of consciousness, including global workspace and higher-order thought theories, hold that these correlates centrally involve prefrontal cortex.  Other leading theories, including first-order and integrated information theories, hold that these correlates centrally involve sensory cortices, with prefrontal cortex playing at most a secondary role.  In recent years much experimental evidence has been brought to bear on both sides of the question.

In this debate, Hakwan Lau (UCLA) and Biyu Jade He (NYU) will defend the view that neural activity in prefrontal cortex is important for conscious perception, while Victor Lamme (Amsterdam) and Johannes Fahrenfort (Amsterdam) will argue that prefrontal activity is not important for conscious perception.

In Sanskrit epistemology, philosophers are preoccupied with the notion of pramā. A pramā, roughly, is a mental event of learning or knowledge-acquisition. Call any such mental event a knowledge-event. In A Confection of Refutation (Khaṇḍanakhaṇḍakhādya), the 12th century philosopher and poet Śrīharṣa argued that knowledge-events are indefinable. Any satisfactory (and therefore non-circular) definition of knowledge-events will have to include an anti-luck condition that doesn’t appeal back to the notion of learning or knowledge-acquisition itself. But there is no such anti-luck condition. What is novel about Śrīharṣa’s argument is that it is motivated by his commitment to a certain “knowledge first” approach to epistemology: the view that knowledge-events are epistemically prior to other non-factive mental states and events. On this view, when we are trying to determine whether an agent has undergone a knowledge-event, we don’t initially ascribe to them some other non-factive mental event, and then check if that event meets some further conditions (like truth or reliability) necessary for it to count as a knowledge-event; rather, we treat certain mental events by default as knowledge-events until a defeater comes along.  Surprisingly, Śrīharṣa argues that this kind of “knowledge first” epistemology should give us reason to doubt whether our ordinary attributions of knowledge-events are reliably tracking any sui generis psychological kind. In this talk, I reconstruct Śrīharṣa’s position.

The speaker will be Prof. Lewis Gordon of the University of Connecticut, on “From Harlem to the World: Philosophy from a Center of the Black World with Questions for the 21st Century.” Gordon will talk about worldliness and public aspects of philosophy, placing them in the context of Harlem both at City College and the public world of Africana philosophy from Du Bois to Malcolm X to contemporaries such as Nathalie Etoke. He will conclude with a set of questions for 21st century philosophy to consider.

Lewis R. Gordon is Professor and Head of the Department of Philosophy at UCONN-Storrs; Honorary President of the Global Center for Advanced Studies; Honorary Professor in the Unit for the Humanities at Rhodes University, South Africa; and Distinguished Scholar at The Most Honourable PJ Patterson Centre for Africa-Caribbean Advocacy at The University of the West Indies, Mona. He co-edits the journal Philosophy and Global Affairs, the Rowman & Littlefield book series Global Critical Caribbean Thought, and the Routledge-India book series Academics, Politics and Society in the Post-Covid World. He is the author of many books, including, most recently, Freedom, Justice, and Decolonization (Routledge, 2021) and Fear of Black Consciousness (hardcover, NY: Farrar, Straus and Giroux, 2022; in the UK, London: Penguin Books, 2022), Picador paperback 2023. He is the 2022 recipient of the Eminent Scholar Award from the Global Development Studies division of the International Studies Association.
