"This guide leads readers systematically through the arguments of Mary Shepherd's two books. Chapters 1-4 cover the arguments in the Essay Upon the Relation of Cause and Effect (1824), where Shepherd argues that causal principles can be known by reason to be necessary truths and that causal inferences can be rationally justified. Shepherd's primary target in this work is Hume, but she also addresses the views of Thomas Brown and William Lawrence. Shepherd considered her second book, Essays on the Perception of an External Universe, and Other Subjects Connected with the Doctrine of Causation (1827), to be an extension of the earlier project on causation; here she appeals to the causal principles established in the first book to argue that we can know through reason that an external world of continually-existing objects must exist independently of us, as the causes of our sensations. Chapter 5 of this Guide addresses Shepherd's accounts of sensation and reasoning; Chapters 6-9 lead the reader through the arguments of the Essays, as well laying out Shepherd's views on skepticism and Berkeleyan idealism, her accounts of mind and body, her philosophy of religion, and the solutions she offers to two puzzles about vision"--

This unique volume attempts to answer one of mankind's oldest puzzles -- why the moon appears to be larger and closer on the horizon than when it is high in the sky. Over the centuries, many viable solutions have been proposed for this psychological phenomenon. The Moon Illusion presents papers by major theorists striving to explain the illusion and providing commentaries on the works of others. Research on the moon illusion has been scattered throughout journals in many disciplines including philosophy, physiology, physics, and psychology. As the first publication to present a comprehensive treatment of the problem, this book is of vital interest to professionals whose major concern is visual perception, experimental psychology, or the neurosciences. Of additional interest to those whose focus is physics or astronomy.

The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world.Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.

This is Volume III of seven in a collection on Philosopher Hegel. Originally published in 1970, this volume looks at Hegel's view on physics.
