William Shatner

Last year, at the age of 90, I had a life-changing experience. I went to space, after decades of playing a science-fiction character who was exploring the universe and building connections with many diverse life forms and cultures. I thought I would experience a similar feeling: a feeling of deep connection with the immensity around us, a deep call for endless exploration. A call to indeed boldly go where no one had gone before.

I was absolutely wrong. As I explained in my latest book, what I felt was totally different. I knew that many before me had experienced a greater sense of care while contemplating our planet from above, because they were struck by the apparent fragility of this suspended blue marble. I felt that too. But the strongest feeling, dominating everything else by far, was the deepest grief that I had ever experienced.

While I was looking away from Earth, and turned towards the rest of the universe, I didn’t feel connection; I didn’t feel attraction. What I understood, in the clearest possible way, was that we were living on a tiny oasis of life, surrounded by an immensity of death. I didn’t see infinite possibilities of worlds to explore, of adventures to have, or living creatures to connect with. I saw the deepest darkness I could have ever imagined, contrasting starkly with the welcoming warmth of our nurturing home planet.

This was an immensely powerful awakening for me. It filled me with sadness. I realised that we had spent decades, if not centuries, being obsessed with looking away, with looking outside. I played my part in popularising the idea that space was the final frontier. But I had to get to space to understand that Earth is, and will remain, our only home. And that we have been ravaging it, relentlessly, making it uninhabitable.

Albert Einstein

The unleashed power of the atom has changed everything except our thinking. Thus, we are drifting toward catastrophe beyond conception. We shall require a substantially new manner of thinking if mankind is to survive.

Neil deGrasse Tyson

I don’t have an issue with what you do in the church, but I’m gonna be up in your face if you’re gonna knock on my science classroom and tell me they’ve got to teach what you’re teaching in your Sunday school. Because that’s when we’re gonna fight!

Happy 16th imgur!! It all circles back

Penn Jillette

If every trace of any single religion were wiped out and nothing were passed on, it would never be created exactly that way again. There might be some other nonsese in its place, but not that exact nonsense. If all of science were wiped out, it would still be true and someone would find a way to figure it all out again.

Robert A. Heinlein - Lost Legacy

When I was a young student, I thought modern psychology could tell me the answers, but I soon found out that the best psychologists didn’t know a damn thing about the real core of the matter. Oh, I am not disparaging the work that has been done; it was badly needed and had been very useful in its way. None of ’em know what life is, what thought is, whether free will is a reality or an illusion, or whether that last question means anything. The best of ’em admit their ignorance; the worst of them make dogmatic assertions that are obvious absurdities.

A dozen Heinlein quotations for sci fi day

Socrates

To believe without evidence and demonstration is an act of ignorance and folly.

Albert Einstein

Since the real purpose of socialism is precisely to overcome and advance beyond the predatory phase of human development, economic science in its present state can throw little light on the socialist society of the future.

Carl Sagan, Pale Blue Dot

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.

Isaac Asimov, The Roving Mind

Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes. I personally resent it bitterly.

Carol Tavris

I see science in general as a form of arrogance control, in the sense that it's one of the most organized methods we have for forcing us to put our beliefs to the test, and forcing us to face dissonance if the test does not confirm what we believe.

Well said ...

Carl Sagan

Extraordinary claims require extraordinary evidence.

Isaac Asimov

I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.

"Extraordinary claims require extraordinary evidence." ~ Carl Sagan

Erich Fromm

What is it that distinguishes man from animals? It is not his upright posture. That was present in the apes long before the brain began to develop. Nor is it the use of tools. It is something altogether new, a previously unknown quality: self-awareness. Animals, too, have awareness. They are aware of objects; they know this is one thing and that another. But when the human being as such was born he had a new and different consciousness, a consciousness of himself; he knew that he existed and that he was something different, something apart from nature, apart from other people, too. He experienced himself. He was aware that he thought and felt. As far as we know, there is nothing analogous to this anywhere in the animal kingdom. That is the specific quality that makes human beings human.

Alan Perlis

The only constructive theory connecting neuroscience and psychology will arise from the study of software.

Thomas Paine

To argue with a person who has renounced the use of reason is like administering medicine to the dead.

I just assume cultists are allergic to facts.

Carl Sagan

Scientists can routinely predict a solar eclipse, to the minute, a millennium in advance. You can go to the witch doctor to lift the spell that causes your pernicious anaemia, or you can take Vitamin B12. If you want to save your child from polio, you can pray or you can inoculate. If you're interested in the sex of your unborn child, you can consult plumb-bob danglers all you want… but they'll be right, on average, only one time in two. If you want real accuracy… try amniocentesis and sonograms. Try science.

Isaac Asimov

There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that ‘my ignorance is just as good as your knowledge.’

Carl Sagan

Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.

Claudius Ptolemaeus

I know that I am mortal by nature and ephemeral, but when I trace at my pleasure the windings to and fro of the heavenly bodies, I no longer touch earth with my feet. I stand in the presence of Zeus himself and take my fill of ambrosia.

Nikola Tesla

If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.
