For my third pick of the draft, I select in the
Scientific category, The Demon Haunted World: Science as a Candle in the Dark, by Carl Sagan.

1995/1997
The Demon-Haunted World: Science as a Candle in the Dark is a book by astrophysicist Carl Sagan and his wife Ann Druyan, which was first published in 1995.
The book is intended to explain the scientific method to laymen, and to encourage people to learn critical or skeptical thinking. It explains methods to help distinguish between ideas that are considered valid science, and ideas that can be considered pseudoscience. Sagan states that when new ideas are offered for consideration, they should be tested by means of skeptical thinking, and should stand up to rigorous questioning.
In the book, Sagan said that if a new idea continues in existence after an examination of the propositions, it should then be acknowledged as a supposition. Skeptical thinking essentially is a means to construct, understand, reason, and recognize valid and invalid arguments.

This is an essential book for any skeptic, anyone interested in critical thinking and anyone interested in science. Sagan does a great job of explaining what science is and what pseudoscience is. I understood the scientific method much better after reading this book. Like every Sagan book he not only explains everything crystal clear, but he also gives the reader more. He gives reasons why critical thinking and being skeptical is a better outlook than superstition and pseudoscience. This is hands down the best book on critical thinking that I have read. Sagan is definitely one of my favorite science writers.
