You could hold this most wonderful device in one hand, yet we build structures that ascend into the skies. The amount of matter in one automobile must be hundreds of times more atoms than in the brain.

This brain thing is actually rather small and there are a finite number of units, all right there, that can cause an, seemingly, infinite number of interactions that result in you and I.

We need to learn about the activities of this small device in order to explain how the soul does it's thing; produce you now.
