What do you discover when you look into your own mind? William James was conﬁ dent: ‘Every one agrees that we there discover states of consciousness’, he said. But a hundred years later we might be inclined to raise a few awkward questions. What does looking mean? Who is looking into what? Does the looking itself change what is seen? Does reporting destroy what we are trying to describe? Can everything be reported when some experiences are supposed to be ineffable? What are states of consciousness anyway?
