Publisher Description
A Harvard researcher investigates the human eye in this insightful account of what vision reveals about intelligence, learning, and the greatest mysteries of neuroscience.
Spotting a face in a crowd is so easy, you take it for granted. But how you do it is one of science's great mysteries. And vision is involved with so much of everything your brain does. Explaining how it works reveals more than just how you see. In We Know It When We See It, Harvard neuroscientist Richard Masland tackles vital questions about how the brain processes information -- how it perceives, learns, and remembers -- through a careful study of the inner life of the eye.
Covering everything from what happens when light hits your retina, to the increasingly sophisticated nerve nets that turn that light into knowledge, to what a computer algorithm must be able to do before it can be called truly "intelligent," We Know It When We See It is a profound yet approachable investigation into how our bodies make sense of the world.

Masland, a Harvard Medical School neuroscience professor, misses the mark in this attempt to explain vision's neurobiological basis to a general audience. He does a very good job of explaining how perception broadly, including vision, works, and even those without any grounding in the fundamentals of biology will be able to gain an appreciation of how the nervous system interacts with the outside world and conveys information to the brain. What works less well is the complexity that intrudes as Masland moves beyond the basics ("If the axons of the retinal ganglion cells synapse upon the neurons of the lateral geniculate nucleus..."), making it unlikely that his target audience will stay with him. His forays into comparing the ways brains process visual stimuli with the ways in which artificial intelligence attempts to accomplish the same task are intriguing but abbreviated, as is his almost fleeting discussion of the nature of consciousness, in which he concludes, "In the end I fear that consciousness is unknowable." Those looking for a scientific explanation of vision will find a useful primer, but those searching for answers to larger questions, such as the one posed by Masland's subtitle, are likely to be disappointed.
