Here are three questions drawn from my work. Rather than try to figure them out, I'm going to ask you to consider for a moment the intuitions and the gut instincts that are going through your head and your heart as you look at them. For example, the calculation: can you feel where on the number line the solution is likely to fall? Or look at the foreign word and the sounds: can you get a sense of the range of meanings that it's pointing you towards? And in terms of the line of poetry, why does the poet use the word hare rather than rabbit? I'm asking you to do this because I believe our personal perceptions, you see, are at the heart of how we acquire knowledge. Aesthetic judgments, rather than abstract reasoning, guide and shape the process by which we all come to know what we know. I'm an extreme example of this.
