''The Demon-Haunted World: Science as a Candle in the Dark''''' is a 1995 book by astrophysicist Carl Sagan.In the book, Sagan aims to explain the scientific method to laypeople, and to encourage people to learn critical and skeptical thinking. He explains methods to help distinguish between ideas that are considered valid science and those 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.==Themes==Science to Sagan is not just a body of knowledge but a way of thinking. The scientific way of thinking is both imaginative and disciplined, bringing humans to an understanding of how the universe is, rather than how they wish to perceive it. Science works much better than any other system because it has a "built-in error-correcting machine". Superstition and pseudoscience get in the way of many laypersons' ability to appreciate the beauty and benefits of science. Skeptical thinking allows people to construct, understand, reason, and recognize valid and invalid arguments. Wherever possible, there must be independent validation of the concepts whose truth should be proved. He states that reason and logic would succeed once the truth were known. Conclusions emerge from premises, and the acceptability of the premises should not be discounted or accepted because of bias.===Dragon in the garage===As an example of skeptical thinking, Sagan offers a story concerning a fire-breathing dragon that lives in his garage. When he persuades a rational, open-minded visitor to meet the dragon, the visitor remarks that they are unable to see the creature. Sagan replies that he "neglected to mention that she's an invisible dragon". The visitor suggests spreading flour on the floor so that the creature's footprints might be seen, which Sagan says is a good idea, "but this dragon floats in the air". When the visitor considers using an infra-red camera to view the creature's invisible fire, Sagan explains that the fire is heatless. He continues to counter every proposed physical test with a reason why the test will not work.Sagan concludes by asking: "Now what's the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all? If there's no way to disprove my contention, no conceivable experiment that would count against it, what does it mean to say that my dragon exists? Your inability to invalidate my hypothesis is not at all the same thing as proving it true."

Wherever possible, there must be independent validation of the concepts whose truth should be proved. He states that reason and logic would succeed once the truth were known. Conclusions emerge from premises, and the acceptability of the premises should not be discounted or accepted because of bias.===Dragon in the garage===As an example of skeptical thinking, Sagan offers a story concerning a fire-breathing dragon that lives in his garage. When he persuades a rational, open-minded visitor to meet the dragon, the visitor remarks that they are unable to see the creature. Sagan replies that he "neglected to mention that she's an invisible dragon". The visitor suggests spreading flour on the floor so that the creature's footprints might be seen, which Sagan says is a good idea, "but this dragon floats in the air". When the visitor considers using an infra-red camera to view the creature's invisible fire, Sagan explains that the fire is heatless. He continues to counter every proposed physical test with a reason why the test will not work.Sagan concludes by asking: "Now what's the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all? If there's no way to disprove my contention, no conceivable experiment that would count against it, what does it mean to say that my dragon exists? Your inability to invalidate my hypothesis is not at all the same thing as proving it true."」の詳細全文を読む
' is a 1995 book by astrophysicist Carl Sagan.In the book, Sagan aims to explain the scientific method to laypeople, and to encourage people to learn critical and skeptical thinking. He explains methods to help distinguish between ideas that are considered valid science and those 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.==Themes==Science to Sagan is not just a body of knowledge but a way of thinking. The scientific way of thinking is both imaginative and disciplined, bringing humans to an understanding of how the universe is, rather than how they wish to perceive it. Science works much better than any other system because it has a "built-in error-correcting machine". Superstition and pseudoscience get in the way of many laypersons' ability to appreciate the beauty and benefits of science. Skeptical thinking allows people to construct, understand, reason, and recognize valid and invalid arguments.
