Carl Sagan just might be my favorite non-fiction author. As Richard Dawkins said, he was incapable of constructing a bad sentence.

One of my favorite parts of this book was the essay "The Dragon in my Garage". The essay argues that if you can't provide any testable or falsifiable evidence for a dragon's existence, then its existence is no different than the absence of a dragon.

Mentioned it in my blog -

"The promise of an afterlife is a cornerstone of many religions, offering comfort in the face of mortality. However, this promise often hinges on the existence of an all-powerful deity, whose nature and existence remain subjects of debate. Central to many afterlife beliefs is the notion of an invisible, immortal soul or spirit capable of experiencing emotions, enabling the concepts of reward or punishment. Yet, no empirical evidence has been found to confirm the existence of such a soul. Acclaimed science author Carl Sagan illustrated this challenge with his “dragon in the garage” analogy. If someone claims to have a dragon that is invisible, silent, intangible, and undetectable by any means, there is no practical difference between the dragon’s existence and non-existence. Similarly, without verifiable evidence, the existence of an immortal soul remains unproven."

My other favorite books from him are -

1. Pale Blue Dot - That "look again at that dot" might be the most poetic thing I've read.

For the unaware, or for those who want to read it again, here's the full quote -

"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known."

2. Cosmos.

3. BILLIONS AND BILLIONS - the part he described coming to know that he had cancer was beautifully written.

4. Shadows of Forgotten Ancestors: A Search for Who We Are with Ann Druyan.

I never read that fiction book he wrote - Contact.

But, man, I'm going to add one of his books to my To Be Read list again lol.

I read this book many years ago and it made a big impression on me.

His view is that normal, rational, intelligent people... can have fictional stories in their heads about how things work. It takes energy and focus and research to fix these wrong stories, so often we live with them or don't recognize them.

Many times I've been casually talking with someone, say something, then realize that doesn't make any sense. My wrong story made sense in my head, but not when I speak it out loud.

By practicing the scientific method, we can gradually weed out the wrong stories in our heads.

Now I'm going to re-read `The Demon-Haunted World`

I once lent my copy to a friend of a friend prone to conspiratorial thinking, who professed to be open-minded and interested in my viewpoint. A few years later, after many reminders, he returned it to me. I asked him what he thought of it. He said he never read it, but it made for a great paper weight. This was the first of many realizations for me that magical thinking cannot be altered with logic.
