Abstract:
The prevalent view in cognitive science is that we construct our perception of reality in real time. But could we be misinterpreting the content of our perceptual experiences? Does what we perceive with our brain and senses reflect the true nature of reality? Might evolution have shaped our perceptions to guide adaptive behavior, without enabling us to see reality as it actually is? In a discussion moderated by Steve Paulson, cognitive scientist Donald D. Hoffman and neurologist Suzanne O'Sullivan analyze these questions and their profound implications for our understanding of human consciousness.
