I couldn't finish this book. I found the book to be mainly ramblings on his observations of aspects of life. I found it to be thoroughly uninteresting and just couldn't finish.

I'm torn on this one, so I'd give it 3.5 but I'm rounding up to 4 stars.

I love Oliver Sacks and the books that I've read by him (The Man Who Mistook His Wife For a Hat and An Anthropologist on Mars are divine). This collection of disparate pieces definitely reflects Sacks' skill at writing about complex topics and making them accessible. I particularly enjoyed the meditations on evolution, memory, and time but, overall, this collection didn't grab my attention in the same way as his other books. I think that many will enjoy this collection, though.

An engrossing collection of Sacks's essays on the subject, the selections in The River of Consciousness are well worth reading -- or rereading, if you're already familiar with Sacks.

Thought-provoking, well-written essays

I enjoyed reading these essays by Oliver Sacks. This is actually the first of his works I’ve read, but now I am hooked. Throughout his essays he gave tangible examples (taken from his other books) to illustrate points he makes. Each time he does this, the subject matter was so interesting that I had to make a mental note to read his other books. I recommend this book for anyone interested in consciousness or just good science writing.
