Over four decades, the Gavin David Young Lectures in Philosophy at the University of Adelaide have become a very significant series with many distinguished contributors from across the globe..  This year, the speaker was Frank Jackson, Professor of Philosophy at ANU. His subject was ‘Philosophy for Representationalists’: perceptual experiences represent the way things are. For example, visual perceptual experiences typically represent how things are in front of us. We can pass this information on in many ways, but we humans most often pass it on using words and sentences. What do these commonplaces about experiences and language tell us about the contents of our experiences and the contents of our words and sentences?
