Our contact with the world is through perception, and therefore the study of the process is of obvious importance and signi?cance. For much of its long history, the study of perception has been con?ned to natural- tic observation. Nonetheless, the phenomena considered worthy of note have not been those that nurture our survival—the veridical features of perception—but the oddities or departures from the common and c- monplace accuracies of perception. With the move from the natural world to the laboratory the oddities of perception multiplied, and they received ever more detailed scrutiny. My general intention is to examine the interpretations of the perc- tual process and its errors throughout history. The emphasis on errors of perception might appear to be a narrow approach, but in fact it enc- passes virtually all perceptual research from the ancients until the present. The constancies of perception have been taken for granted whereas - partures from constancies (errors or illusions) have fostered fascination.

“The uncanny beauty of Van Booy’s prose, and his ability to knife straight to the depths of a character’s heart, fill a reader with wonder.” — San Francisco Chronicle Award-winning author Simon Van Booy tells a harrowing and enchanting story of how one man’s act of mercy during World War II changed the lives of strangers, and how they each discover the astonishing truth of their connection. The characters in Van Booy's The Illusion of Separateness discover at their darkest moments of fear and isolation that they are not alone, that they were never alone, that every human being is a link in a chain we cannot see. This gripping novel—inspired by true events—tells the interwoven stories of a deformed German infantryman; a lonely British film director; a young, blind museum curator; two Jewish American newlyweds separated by war; and a caretaker at a retirement home for actors in Santa Monica. They move through the same world but fail to perceive their connections until, through seemingly random acts of selflessness, a veil is lifted to reveal the vital parts they have played in one another's lives, and the illusion of their separateness.

Most of us believe that we are unique and coherent individuals, but are we? The idea of a "self" has existed ever since humans began to live in groups and become sociable. Those who embrace the self as an individual in the West, or a member of the group in the East, feel fulfilled and purposeful. This experience seems incredibly real but a wealth of recent scientific evidence reveals that this notion of the independent, coherent self is an illusion - it is not what it seems. Reality as we perceive it is not something that objectively exists, but something that our brains construct from moment to moment, interpreting, summarizing, and substituting information along the way. Like a science fiction movie, we are living in a matrix that is our mind. In The Self Illusion, Dr. Bruce Hood reveals how the self emerges during childhood and how the architecture of the developing brain enables us to become social animals dependent on each other. He explains that self is the product of our relationships and interactions with others, and it exists only in our brains. The author argues, however, that though the self is an illusion, it is one that humans cannot live without. But things are changing as our technology develops and shapes society. The social bonds and relationships that used to take time and effort to form are now undergoing a revolution as we start to put our self online. Social networking activities such as blogging, Facebook, Linkedin and Twitter threaten to change the way we behave. Social networking is fast becoming socialization on steroids. The speed and ease at which we can form alliances and relationships is outstripping the same selection processes that shaped our self prior to the internet era. This book ventures into unchartered territory to explain how the idea of the self will never be the same again in the online social world.
