""A Theory of Sight: Or How We See, And What We See"" is a scientific treatise written by H. F. Goblet and published in 1869. The book explores the human sense of sight, delving into the anatomy and physiology of the eye, as well as the psychological and cognitive processes that allow us to perceive and interpret visual information. Goblet discusses the various factors that influence visual perception, including light, color, distance, and motion, and proposes a theoretical framework for understanding how these factors interact to create the visual world we experience. The book is a comprehensive study of vision and remains a valuable resource for researchers and students of neuroscience, psychology, and optics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
