What is thought? Where does it come from? My suspicion is that it has to do with complicated biological processes involving chemicals and stimuli, but then again, I'm not sure how the garage door opener works.
Spark is a deceptive book... deceptively simple. There seems to be something far deeper beneath the surface, and some very passionate, personally-held ideas by the author, Esty Raskin, though I'm still parsing what exactly they are. At the moment, I can say with certainty that there is this little fellow named Spark. He exists inside of our heads. He speaks through us, but can also be buried beneath too much language. He makes us happy and he makes us sad. He seems to be both us and not us.
