Seeing Black And White

Reviews the history of the scientific development of lightness theory and outlines and critiques the theories of lightness, laying out the strengths and weaknesses of each. This work presents author's argument that previous models of lightness perception fail to capture the errors and illusions present in human perception.

Perception is reality in this semi coming to afar piece about a young black man, living in a world of racial and economic inequities. Inspired in part by Gil Scott Heron’s track “B Movie”, the story takes readers on a journey beginning in the mid 90’s into the present day, chronicling many of the real issues faced by young black men, and the role of their white counterparts. Follow our protagonist as he views the world, “in black and white.”

How the human visual system determines the lightness of a surface, that is, its whiteness, blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even been able to create a machine that can determine, through an artificial vision system, whether an object is white, black, or gray. Although the photoreceptors in the eye are driven by light, the light reflected by a surface does not reveal its shade of gray. Depending upon the level of illumination, a surface of any shade of gray can reflect any amount of light. In Seeing Black and White Alan Gilchrist ties together over 30 years of his own research on lightness, and presents the first comprehensive, historical review of empirical work on lightness, covering the past 150 years of research on images ranging from the simple to the complex. He also describes and analyzes the many theories of lightness--including his own--showing what each can and cannot explain. Gilchrist highlights the forgotten-yet-exciting work done in the first third of the twentieth century, describing several crucial experiments and examining the brilliant but nearly unknown work of the Hungarian gestalt theorist, Lajos Kardos. Gilchrists review also includes a survey of the pattern of lightness errors made by humans, many of which result in delightful illusions. He argues that because these errors are not random, but systematic, they are the signature of our visual software, and so provide a powerful tool that can reveal how lightness is computed. Based on this argument and the concepts of anchoring, grouping, and frames of reference, Gilchrist presents a new theoretical framework that explains an unprecedented array of lightness errors. As both the first comprehensive overview of research on lightness and the first unified presentation of Gilchrists new theoretical framework Seeing Black and White will be an invaluable resource for vision scientists, cognitive psychologists, and cognitive neuroscientists.

Everyone agrees that America is polarized, with ever-hardening positions held by people less and less willing to listen to one another. No one agrees on what to do about it. One solution that hasn’t yet been tried, says Adam Hamilton, is for thinking persons of faith to model for the rest of the country a richer, more thoughtful conversation on the political, moral, and religious issues that divide us. Hamilton rejects the easy assumptions and sloppy analysis of black and white thinking, seeking instead the truth that resides on all sides of the issues, and offering a faithful and compassionate way forward. He writes, "I don't expect you to agree with everything I've written. I expect that in the future even I won't agree with everything I've written here. The point is not to get you to agree with me, but to encourage you to think about what you believe. In the end I will be inviting those of you who find this book resonates with what you feel is true, to join the movement to pursue a middle way between the left and the right - to make your voices heard - and to model for our nation and for the church, how we can listen, learn, see truth as multi-sided, and love those with whom we disagree."
