You'll enjoy reading Stefan's post on what he thinks of Five Senses. Here is the introductory tidbit:
How to approach this book on the five senses (that aren't really five after all)? I loved it, but it's so hard to explain why. It's more the ideas it gives birth to than what's in it. But let me try:
Take your index finger and place it on your bottom lip. Do it! You have to do it, or you wont understand this post. Please do it.
Now, without moving, fix your attention on feeling your lip through your finger (do it, take your time, close your eyes if it helps). OK? Now, shift perspective, and feel your finger through your lip. Isn't that amazing?! One moment you are in your finger, feeling your lip - another moment you are in your lip, feeling your finger! Your consciousness, your self-awareness is somehow shifting place, moving from inside your lip and outside your finger to inside your finger and outside your lip. Yet only one event, one touch, is actually happening. So where are you? In this encounter, this relation, this instance of first-hand knowledge, you are both the knowing subject and the known object. You are outside and inside.
