Let there be no doubt. Alien technology harvested from the infamous saucer crash in Roswell, N.Mex., in July 1947 led directly to the development of the integrated circuit chip, laser and fiber optic technologies, Particle beams, Electromagnetic propulsion systems, Depleted uranium projectiles, Stealth capabilities, and many others! How do I know? I was in charge! A matter of public record I think the kids on this planet are wise to the truth, and I think we ought to give it to them. I think they deserve it.

If the average man thinks at all, he does silly things like generalizing from a single datum. He uses one-valued logics. If he is exceptionally bright, he may use two-valued, 'either-or' logic to arrive at his wrong answers. If he is hungry, hurt, or personally interested in the answer, he can't use any sort of logic and will discard an observed fact as blithely as he will stake his life on a piece of wishful thinking. He uses the technical miracles created by superior men without wonder nor surprise, as a kitten accepts a bowl of milk. Far from aspiring to higher reasoning, he is not even aware that higher reasoning exists. He classes his own mental proccess as being of the same sort as the genius of an Einstein. Man is not a rational animal; he is a rationalizing animal.

Robert A. Heinlein - Friday

My grandparents used to tell me about a time when people were polite and nobody hesitated to be outdoors at night and people often didn't even lock their doors-much less surround their homes with fences and walls and barbed wire and lasers. Maybe so; I'm not old enough to remember it. It seems to me that, all my life, things have grown worse and worse.

Robert A. Heinlein - Revolt in 2100, Postscript

The capacity for the human mind for swalling nonsense and spewing it forth in violent and repressive action has never yet been plumbed.

Robert A. Heinlein - Glory Road

Women and cats will do as they please, and men and dogs should relax and get used to the idea.

Robert A. Heinlein - Friday

It is not written in the stars that I will always understand what is going on — a truism that I often find damnably annoying.

Robert A. Heinlein - Time Enough For Love

Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded — here and there, now and then — are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty.

This is known as "bad luck"...

Being intelligent is not a felony, but most societies evaluate it as at least a misdemeanor.

Robert A. Heinlein - To Sail Beyond the Sunset

But there seems to have been an actual decline in rational thinking. The United States had become a place where entertainers and professional athletes were mistaken for people of importance. They were idolized and treated as leaders; their opinions were sought on everything and they took themselves just as seriously — after all, if an athlete is paid a million or more a year, he knows he is important … so his opinions of foreign affairs and domestic policies must be important, too, even though he proves himself to be both ignorant and subliterate every time he opens his mouth. (Most of his fans were just as ignorant and unlettered; the disease was spreading.)

Socrates

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

F. Frankfort Moore

I think that if a mortal heard the word of God it would be in a garden at the cool of the day.

Albert Camus

The only way to deal with an unfree world is to become so absolutely free that your way of existence is an act of rebellion.

Naguib Mahfouz

Home is not where you were born; home is where all your attempts to escape cease.

Mark Twain

The human race has one really effective weapon, and that is laughter.
