Thoughts on the misrepresentation of Carl Sagan

My parents were not scientists. They knew almost nothing about science. But in introducing me simultaneously to scepticism and to wonder, they taught me the two uneasily cohabiting modes of thought that are central to the scientific method.
Carl Sagan - THE DEMON-HAUNTED WORLD [1997, p.3]



Sagan could be called a Pantheistic Spinozean where God is nature, the sum total of the physical laws which describe our universe,,,(similar to Einstein), ",,,madness to deny the existence of physical laws." [Broca's Brain, p 330]

Also know for (re) coining the phrase, "Extraordinary claims require extraordinary evidence"

His wife Ann Druyan sums it up best,,,

When my husband died, because he was so famous and known for not being a believer, many people would come up to me-it still sometimes happens-and ask me if Carl changed at the end and converted to a belief in an afterlife. They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don't ever expect to be reunited with Carl. But, the great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief and precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting. Every single moment that we were alive and we were together was miraculous-not miraculous in the sense of inexplicable or supernatural. We knew we were beneficiaries of chance. . . . That pure chance could be so generous and so kind. . . . That we could find each other, as Carl wrote so beautifully in Cosmos, you know, in the vastness of space and the immensity of time. . . . That we could be together for twenty years. That is something which sustains me and it’s much more meaningful. . . . The way he treated me and the way I treated him, the way we took care of each other and our family, while he lived. That is so much more important than the idea I will see him someday. I don't think I'll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful.

So was Carl Sagan a believer? In science yes,,,to represent his views in any other light is a disservice to him, his work and his memory. You either accept science or you don't. You can not cherry-pick the parts of science that fit a preconceived hypothesis whilst ignoring the rest.

One final thought,,,

One prominent American religion confidently predicted that the world would end in 1914. Well, 1914 has come and gone, and - whole the events of that year were certainly of some importance - the world did not, at least so far as I can see, seem to have ended. There are at least three responses that an organized religion can make in the face of such a failed and fundamental prophecy. They could have said, Oh, did we say '1914'? So sorry, we meant '2014'. A slight error in calculation. Hope you weren't inconvenienced in any way. But they did not. They could have said, Well, the world would have ended, except we prayed very hard and interceded with God so He spared the Earth. But they did not. Instead, the did something much more ingenious. They announced that the world had in fact ended in 1914, and if the rest of us hadn't noticed, that was our lookout. It is astonishing in the fact of such transparent evasions that this religion has any adherents at all. But religions are tough. Either they make no contentions which are subject to disproof or they quickly redesign doctrine after disproof. The fact that religions can be so shamelessly dishonest, so contemptuous of the intelligence of their adherents, and still flourish does not speak very well for the tough- mindedness of the believers. But it does indicate, if a demonstration was needed, that near the core of the religious experience is something remarkably resistant to rational inquiry. [Broca's Brain, p. 332]


I worry that, especially as the Millennium edges nearer, pseudoscience and superstition will seem year by year more tempting, the siren song of unreason more sonorous and attractive. Where have we heard it before? Whenever our ethnic or national prejudices are aroused, in times of scarcity, during challenges to national self-esteem or nerve, when we agonize about our diminished cosmic place and purpose, or when fanaticism is bubbling up around us-then, habits of thought familiar from ages past reach for the controls.

The candle flame gutters. Its little pool of light trembles. Darkness gathers. The demons begin to stir. [Demon Haunted World, p. 29]

Parallel Universes & Quantum Mechanics | LifesLittleMysteries.com

In my parallel universe I didn't have to read this 3 times,,,

One derivation of parallel universes comes from the kookiness of quantum mechanics. At subatomic scales, particles do not act in a concrete, there-or-not-there manner that we are accustomed to in our spatial environments. Instead, and bizarrely, particles possess various physical properties and occupy multiple positions. None of these characteristics can be known beyond a certain probability range until the particle is observed. [The Mysterious Physics of 7 Everyday Things]


Accordingly, particles exist in a fuzzy "wavefunction" of probable states. Although a measurement nails down one of these multiple possible states, it is thought that other possible values "branch off" into their own universes.


"Through quantum mechanics, there is an idea that there are many possible outcomes and those are represented in the wavefunction," Albrecht said. Some scientists regard those different outcomes as different parallel universes.

Very curious

An interesting article, would love to find more information especially about the three Christs; I may have to look for the book. The alone in the dark bit also is intriguing.

Wondering were this fits into the bigger picture of thing

Altho I'm a deistic agnostic who does not believe in creationism, stories like this one make me shake my head in confusion. Must learn more ,,,

Darwin anyone??

Yes I did say Darwin, as in Charles Darwin. I'm not sure how I came across this gem of a site but if you want to delve into the father of evolutionary theory this is the site to do it. What's even better is they have many of his works available as audio downloads.


Online since 2002, The Complete Work of Charles Darwin Online (or Darwin Online) is the largest and most widely consulted edition of the writings of Darwin ever published. More copies of Darwin's works have been downloaded from Darwin Online than have been printed by all publishers of the past 180 years combined.

This website contains over 98,000 pages of searchable text and 213,000 electronic images, at least one exemplar of all known Darwin publications, reproduced to the highest scholarly standards, both as searchable text and electronic images of the originals. The majority of these have been edited and annotated here for the first time with thousands of original editorial notes.

Isn't this a no brainer?

"Religious viewpoints need not conflict with science. Several prominent religious biologists, including my friends Ken Miller at Brown University in Providence, Rhode Island, and Francis Collins at the US National Institutes of Health, make it quite clear that one doesn't have to be an atheist to accept the scientific fact of evolution. Incorrect interpretations of empirical data to fit in with religious beliefs should not be legally protected."

Parallel universes or as Paul Eno so often says,,,the multiverse

A Physicist Explains Why Parallel Universes May Exist

"Our universe might be really, really big — but finite. Or it might be infinitely big.

Both cases, says physicist Brian Greene, are possibilities, but if the latter is true, so is another posit: There are only so many ways matter can arrange itself within that infinite universe. Eventually, matter has to repeat itself and arrange itself in similar ways. So if the universe is infinitely large, it is also home to infinite parallel universes.

Does that sound confusing? Try this,,,"
