""A Theory of Sight: Or How We See, and What We See"" is a book written by H. F. Goblet and first published in 1869. The book explores the science behind human vision and perception, delving into the anatomy and physiology of the eye, the mechanics of light and color, and the psychology of visual perception. Goblet draws on the latest scientific research of his time to offer a comprehensive explanation of how the human eye works and how our brains interpret visual information. He also discusses the various optical illusions and perceptual distortions that can occur, and how our understanding of these phenomena can help us better understand the workings of the human mind. This book is an important contribution to the field of vision science and remains relevant today for anyone interested in the science behind how we see and perceive the world around us.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
