On page 1 of the prologue Jeff writes:
I suffer from passion attention deficit disorder (PADD). I am of the same temporal generation as Jeff Hawkins, a child of the space, computer, and nuclear age. I cannot even remember when I first wondered how people can be intelligent and conscious. Such wonder was in the air of the science fictions novels I read as a child. But I have other passions as well. So I have engaged in a variety of pursuits over the decades, only once in a while returning to the contemplation of machine understanding and its related issues of biology, philosophy, and technology.
But I have a second passion that predates my interest in computers, one I view as more important. I am crazy about brains. I want to understand how the brain works, not just from a philosophical perspective, not just in a general way, but in a detailed nuts and bolts engineering way.
Hopefully my interest in literature and writing, history, gardening, politics, and art will bring something to this enterprise. If nothing else, I can chronicle the field's development. And I hope to range into any topic that could be helpful in the endeavor, not just neuroscience and computer technology.
