In this freshly updated, comprehensive study, political scientist David Koyzis surveys the key political ideologies of our era, unpacking the worldview issues inherent to each and pointing out essential strengths and weaknesses. Writing with broad international perspective, Koyzis is a sensible guide for Christians working in the public square, culture watchers, and all students of modern political thought.
Visual illusions are compelling phenomena that draw attention to the brain's capacity to construct our perceptual world. The Compendium is a collection of over 100 chapters on visual illusions, written by the illusion creators or by vision scientists who have investigated mechanisms underlying the phenomena. --
Fascinating, profusely illustrated study explores the psychology and physiology of vision, including light and color, motion receptors, the illusion of movement, much more. Over 100 illustrations.
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.
In this volume, originally published in 1978, the authors survey the historical and contemporary research literature pertaining to two-dimensional visual-geometric illusions. They bring together much of the known data, summarising and evaluating theories that have been offered to explain these phenomena. Coren and Girgus provide a new conceptual framework that suggest that visual illusions are not unitary phenomena. Within this framework, illusions do not represent a breakdown in normal perceptual processing. Rather, it is proposed that each illusion is produced by a number of mechanisms operating at different levels in the visual information processing system. The book contains an extensive collection of illusion figures. It will be essential reading for all of those concerned with vision and visual perception, since it integrates the study of illusions into the main body of psychological and perceptual theories at the time.
"Incredible Visual Illusions is the most comprehensive and amazing collection of optical illusions ever assembled, with almost three hundred different artworks. You will be amazed as some images flash and scintillate before your eyes, while others disappear right in front of you. Size and shape can lose their meaning, you'll see motion where there is no motion and the laws of perspective are turned on their heads! You won't believe your eyes!" --
Throughout the book, each image is accompanied by an explanation of how it works, the story behind it – when it was discovered or who invented it first – and the details of exactly why it fools the human brain. The book includes many new and previously unpublished illusions, as well as new adaptations of lesser-known illusions. It also includes works by well-known illusion artists such as Bridget Riley, Salvador Dalí, Giuseppe Arcimboldo, Oscar Reutersvärd, René Magritte, István Orosz and Rob Gonsalves. There are chapters on the following subjects: optical illusions from the real world (mirage, refraction, afterimage), ambiguous figures, impossible figures, color adaptation, moving illusions and paradoxical illusions.
" The Civil War scene in Kentucky, site of few full-scale battles, was one of crossroad skirmishes and guerrilla terror, of quick incursions against specific targets and equally quick withdrawals. Yet Kentucky was crucial to the military strategy of the war. For either side, a Kentucky held secure against the adversary would have meant easing of supply problems and an immeasurably stronger base of operations. The state, along with many of its institutions and many of its families, was hopelessly divided against itself. The fiercest partisans of the South tended to be doubtful about the wisdom of secession, and the staunchest Union men questioned the legality of many government measures. What this division meant militarily is made clear as Lowell H. Harrison traces the movement of troops and the outbreaks of violence. What it meant to the social and economic fabric of Kentucky and to its postwar political stance is another theme of this book. And not forgotten is the life of the ordinary citizen in the midst of such dissension and uncertainty.
While many acknowledge that Friedrich Nietzsche and Michel Foucault have redefined our notions of time and history, few recognize the crucial role that 'the infinite relation' between seeing and saying plays in their work. Shapiro reveals the full extent of Nietzsche and Foucault's concern with the visual.
