The universe is not only strange but stranger than we can imagine


Who to trust?

No statement should be believed because it is made by an authority.


The road to tyranny




“Almost any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so.”


The vital importance of facts


What are the facts? Shun wishful thinking, ignore divine revelation, forget what “the stars foretell,” avoid opinion, care not what the neighbors think, never mind the unguessable “verdict of history”–what are the facts, and to how many decimal places? You pilot always into an unknown future, facts are your single clue.

ROBERT A. HEINLEIN, The Notebooks of Lazarus Long

Wars of religion are the most detestable


“If religions are diseases of the human psyche, as the philosopher Grintholde asserts, then religious wars must be reckoned the resultant sores and cankers infecting the aggregate corpus of the human race. Of all wars, these are the most detestable, since they are waged for no tangible gain, but only to impose a set of arbitrary credos upon another’s mind.”

Jack Vance, The Face

Why anything?

Dying Earth



“Notice this rent in my garment; I am at a loss to explain its presence! I am even more puzzled by the existence of the universe.”

― Jack Vance, Tales of the Dying Earth

And reality again

I hope I shall arrive soon



“Reality is that which, when you stop believing in it, doesn’t go away.”

Philip K. Dick, I Hope I Shall Arrive Soon


Farenheit 451


“Stuff your eyes with wonder, he said, live as if you’d drop dead in ten seconds. See the world. It’s more fantastic than any dream made or paid for in factories.”

Ray Bradbury, Fahrenheit 451

SF Quotes: The futility of Sweetness and Light

Have Space Suit“I’ve heard all the usual Sweetness and Light that kids get pushed at them—how they should always forgive, how there’s some good in the worst of us, etc. But when I see a black widow, I step on it; I don’t plead with it to be a good little spider and please stop poisoning people. A black widow spider can’t help it—but that’s the point.”

Robert Heinlein, Have Space Suit — Will Travel

SF Quotes: the value of an open mind


“I myself have seen strange and terrifying sights. Were they hallucinations? Were they the manipulation of the cosmos by my mind, or by the mind of someone — or something — other than myself?

I do not know. I therefore counsel a flexible attitude towards matters where the truth is still unknown. For this reason: the impact of an inexplicable experience may well destroy a mind which is too brittle.”

Jack Vance, Sail 25

SF Quotes: Knowledge and freedom

wpid-101013_ov_Heinlein_Revolt_in_2100_If_This_Goes_On“When any government, or any church for that matter, undertakes to say to its subjects, ‘This you may not read, this you must not see, this you are forbidden to know,’ the end result is tyranny and oppression, no matter how holy the motives.

Mighty little force is needed to control a man whose mind has been hoodwinked; contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, not anything—you can’t conquer a free man; the most you can do is kill him.”

—Robert A. Heinlein, If This Goes On, 1940
