Think about it. As you look at someone, particles of light energy are being absorbed by your eyes’ receptor cells, converted into neural signals that activate neighboring cells, which down the line transmit a million electrochemical messages per moment up to your brain. There, separate parts of your brain process information about color, form, motion, and depth, and then – in some still mysterious way – combine this information to form a consciously perceived image that is instantly compared with previously stored images and recognized as, say, your grandmother. The whole process is as complex as taking a house apart, splinter by splinter, transporting it to a different location, and then through the efforts of millions of specialized workers, putting it back together. Voila! The material brain gives rise to consciousness. That all of this happens instantly, effortlessly, and continuously is better than cool; it is truly bewildering. In explaining such phenomena I empathize with Job: ‘I have uttered what I did not understand, things too wonderful for me’ (Job 42:3 NRSV).
