Lydialyle Gibson in Harvard Magazine:
A specialist in epistemology and the philosophy of mind, Siegel has always been fascinated by perception: what and how we see, and the effect that has on what we can know. Her 2010 book, The Contents of Visual Experience, argued that conscious visual perception includes all kinds of complex properties: not just color, shape, light, and motion, but other, richer attributes, too. For instance, it encompasses what kind of thing we see—a tree, a bicycle, a dog?—and causal characteristics, like the property a knife can have while slicing through a piece of bread. Perception can even involve personal identity, Siegel argued: the property of being John Malkovich. The book’s central claim was that being able to visually recognize things, such as one’s own neighborhood, or pine trees, or John Malkovich, can influence how those things look to the person who sees them.
But as she was finishing that book, another question began to bother her: if being able to recognize your neighborhood influences how it looks to you, then couldn’t beliefs, desires, and fears do the same? And if prior beliefs could influence someone’s visual experience, how might those experiences, in turn, strengthen those very beliefs?
