As a member of the choir to whom Sagan is preaching, I have found this book wonderful. I am skeptical of its efficacy to persuade those who do not agree with the book a priori. Does it work to use reason to argue for reason, when the audience does not use reason? I have my doubts.

An essential course in critical thinking that should be on every bookshelf, and taught in schools.

Carl Sagan provides indispensable information in order to be a well-informed rational citizen, provided that one wants to live in a sane society, or help create one. I did find it a bit long-winded and repetitive about quackery. All in all it was worth the purchase.

Give this book to your friend who believes some magical super food like kombucha or yak scrotum can cure anything from cancer to aids, all autoimmune diseases, and death.
