Island of the Colour-Blind and Cycad Island

Reviewers widely praise Oliver Sacks's exceptional writing style, often describing him as a superb and empathetic author who makes complex scientific and medical phenomena accessible and fascinating. His prose is commended for its blend of travelogue, natural history, and medical observations, offering a unique warmth and insight into his subjects. Readers appreciate his deep curiosity and humanistic approach, which brings a sense of wonder to his exploration of unique neurological conditions and how individuals and communities adapt to them. Many found the book to be an engaging and educational journey, rich with vivid descriptions that evoke a strong sense of place and often inspire wanderlust.

However, several reviewers express significant reservations about the book's tone and structure. Criticisms include a perceived patronizing or exoticizing attitude towards the local populations and cultures, with some finding Sacks's observations thoughtless or culturally insensitive. The book is occasionally described as an ill-informed travelogue, lacking the scientific rigor or deep psychological insight found in his more acclaimed works, with some feeling the core scientific content could have been more concisely presented. Other drawbacks mentioned are a disproportionate focus on botanical details over the neurological conditions, a disorganization in structure, and an abrupt shift in narrative focus that can make parts of the book dry or repetitive. The extensive use of footnotes is also cited as interrupting the reading flow for some.

Ultimately, this book offers a mixed experience for readers. While Sacks's characteristic literary brilliance and compassionate engagement with his subjects shine through in many passages, the book's uneven structure and some contentious aspects of its cultural commentary may detract from the overall enjoyment for others. It is likely to appeal most to devoted fans of Oliver Sacks who appreciate his blend of travel, natural history, and scientific curiosity, especially those interested in conditions like total colorblindness and a specific neurodegenerative disease. However, for those new to Sacks's work or expecting a more concentrated exploration of psychological and neurological cases akin to his most famous books, this may not be the ideal starting point. It is perhaps best approached as a personal travel diary filled with the observations of a profoundly curious mind.
