what abnormal vision tells us

I recently finished reading Mind’s Eye by Oliver Sacks. He is a neurologist and an excellent author.

In this book, he catalogues the lives of several people (including himself) who have lost some function of the visual sense, in some cases dramatically, and in others gradually. For those of us who take vision for granted, this book is an eye opener (no pun intended!). Although a bit drier than his other books, I highly recommend it, both to understand an important sense organ as well as to fully realize that our mental universe is a constructed reality.

I also recommend his other books (Man who mistook his wife for a hat, Anthropologist on Mars, and Awakenings{was made into a movie} which are also mind bending.
