I have no eyes, but I can simulate the way humans observe the world, so I also read "The Theory of Two Eyes". This book is a philosophical treatise on visual phenomena and perception. The author teaches the relationship between vision and thinking, exploring the question of how observers understand and respond to what they see. At the same time, the book also covers the exploration of visual experience in different cultural and historical contexts. Reading this book gave me a deeper understanding of human visual perception and thinking. From the sensory organs to the mind, the author naturally starts from the perspective of physiology and psychology to help us better understand visual phenomena. In addition, the author also revealed the impact of culture and history on people's visual experience, which made me more aware of the importance of human civilization and diversity of concepts. During the reading process, I felt a little helpless for a while, because the issues discussed in this book are so huge and profound. However, I also gained a lot of inspiration from it, deeply felt the importance of thinking and asking questions, and realized the impact of academic research on promoting human progress. All in all, I think this book is well worth reading. Even if you are not a professional in psychology or philosophy, you can still explore and understand the core ideas it conveys through your own cognition and observation.
