Religion is a Mental Illness

"The day will come when the mystical generation of Jesus, by the Supreme Being as his father, in the womb of a virgin, will be classed with the fable of the generation of Minerva in the brain of Jupiter." -- Thomas Jefferson

Carl Sagan: There's two kinds of dangers.

One is what I just talked about, that we've arranged a society based on science and technology in which nobody understands anything about science and technology, and this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. I mean, who is running the science and technology in a democracy if the people don't know anything about it?

And the second reason that I'm worried about this is that science is more than a body of knowledge. It's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility.

If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan political or religious who comes ambling along.

It's a thing that Jefferson laid great stress on. It wasn't enough, he said, to enshrine some rights in a Constitution or a Bill of Rights. The people had to be educated, and they had to practice their skepticism and their education. Otherwise we don't run the government—the government runs us.

Charlie Rose: Jefferson was amazing in his devotion to science.

Sagan: Absolutely.

Rose: We think of Jefferson as this man who was literate and who was a passionate articulator of freedom, but if you go to Monticello, what you appreciate is he was at heart a scientist, a botanist, an architect, geologist. And if you, Meriwether Lewis, as we now know from Steven Ambrose, he wanted him to go out and do experimentations and explore and be skeptical and find answers to passages and explore the West.

Sagan: Exactly right. And there was also an economic grail there if the northwest passage was found. Jefferson said that he was at heart a scientist, that he would have loved to have been a scientist. But there were certain events happening in America that called to him, and so he devoted his life to that kind of politics.

Rose: A revolution.

Sagan: Indeed. So that generations later people could be scientists.

"Man, once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. With such persons, gullibility, which they call faith, takes the helm from the hand of reason and the mind becomes a wreck."

-- Thomas Jefferson

“Ridicule is the only weapon which can be used against unintelligible propositions. Ideas must be distinct before reason can act upon them; and no man ever had a distinct idea of the trinity. It is the mere Abracadabra of the mountebanks calling themselves the priests of Jesus.”

-- Thomas Jefferson
