"I have collected and juxtaposed thousands of quotes and images from every branch of knowledge and art, thinking of the book as if it were built like a brain. Just as there are synaptic gaps between neurons, there are blank spaces in the book between the quotes and images. The reader’s interpretation traverses the gap, just as the neurotransmitter fires an electric signal across the gap between nerve cells. The synaptic gap does not close, and in fact, must remain open for the next transmission. Communication and learning require a gap." jts
