Oh, for a pin that would puncture pretension!
I have never, in all my life, not for one moment, been tempted toward religion of any kind. The fact is that I feel no spiritual void. I have my philosophy of life, which does not include any aspect of the supernatural and which I find totally satisfying. I am, in short, a rationalist and believe only that which reason tells me is so.
Now remember, kids, the internet is serious business.
A myth or legend is simply not made up out of a vacuum. Nothing is--or can be. Somehow there is a kernel of truth behind it, however distorted that might be.

Speech, originally, was the device whereby Man learned, imperfectly, to transmit the thoughts and emotions of his mind. By setting up arbitrary sounds and combinations of sounds to represent certain mental nuances, he developed a method of communication--but one which in its clumsiness and thick-thumbed inadequacy degenerated all the delicacy of the mind into gross and guttural signaling.
Why ... did so many people spend their lives not trying to find answers to questions -- not even thinking of questions to begin with? Was there anything more exciting in life than seeking answers?

The final end of Eternity, and the beginning of Infinity
If you suspect that my interest in the Bible is going to inspire me with sudden enthusiasm for Judaism and make me a convert of mountain-moving fervor and that I shall suddenly grow long earlocks and learn Hebrew and go about denouncing the heathen - you little know the effect of the Bible on me. Properly read, it is the most potent force for atheism ever conceived.
The further a device is removed from human control, the more authentically mechanical it seems, and the whole trend in technology has been to devise machines that are less and less under direct human control and more and more under their own apparent will.
It's the writing that teaches you.

All the hundreds of millions of people who, in their time, believed the Earth was flat never succeeded in unrounding it by an inch.
Naturally, since [the Sumerians] didn't know what caused the flood anymore than we do, they blamed the gods. (That's the advantage of religion. You're never short an explanation for anything.)

If I had felt then as I feel now, or as I felt a few years after I had married her, nothing could possibly have persuaded me to marry a woman who smoked. Dates, yes. Sexual adventures, yes. But to pin myself permanently inside closed quarters with a smoker? Never. Never. Never. Beauty wouldn't count, sweetness wouldn't count, suitability in every other respect wouldn't count.
People are entirely too disbelieving of coincidence.
Scientists derive satisfaction from figuring out the puzzle. It's about the quest, not the grail.
Dreams may be impossible, yet still be dreamed.
Korell is that frequent phenomenon in history : the republic whose ruler has every attribute of the absolute monarch but the name. It therefore enjoyed the usual despotism unrestrained even by those two moderating influences in the legitimate monarchies: regal "honor" and court etiquette.
The world in general disapproves of creativity, and to be creative in public is particularly bad. Even to speculate in public is rather worrisome.
There are so many benefits to be derived from space exploration and exploitation; why not take what seems to me the only chance of escaping what is otherwise the sure destruction of all that humanity has struggled to achieve for 50,000 years?

The cure for advanced gullibility is to go to sleep and consider matters again the next day.
However much the creationist leaders might hammer away at their scientific and philosophical points, they would be helpless and a laughing-stock if that were all they had. It is religion that recruits their squadrons. Tens of millions of Americans, who neither know nor understand the actual arguments for - of even against - evolution, march in the army of the night, their Bibles held high. And they are a strong and frightening force, impervious to, and immunized against, the feeble lance of mere reason.
The Earth faces environmental problems right now that threaten the imminent destruction of civilization and the end of the planet as a livable world. Humanity cannot afford to waste its financial and emotional resources on endless, meaningless quarrels between each group and all others. there must be a sense of globalism in which the world unites to solve the real problems that face all groups alike.
A scientist is as weak and human as any man, but the pursuit of science may ennoble him even against his will.
Computerization eliminates the middleman
I stand four-square for reason, and object to what seems to me to be irrationality, whatever the source. If you are on my side in this, I must warn you that the army of the night has the advantage of overwhelming numbers, and, by its very nature, is immune to reason, so that it is entirely unlikely that you and I can win out. We will always remain a tiny and probably hopeless minority, but let us never tire of presenting our view, and of fighting the good fight for the right.
Writing is my only interest. Even speaking is an interruption.
There is nothing frightening about an eternal dreamless sleep. Surely it is better than eternal torment in Hell and eternal boredom in Heaven.

It's not so much what you have to learn if you accept weird theories, it's what you have to UNlearn.

The law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.
One might suppose that reality must be held to at all costs. However, though that may be the moral thing to do, it is not necessarily the most useful thing to do. The Greeks themselves chose the ideal over the real in their geometry and demonstrated very well that far more could be achieved by consideration of abstract line and form than by a study of the real lines and forms of the world; the greater understanding achieved through abstraction could be applied most usefully to the very reality that was ignored in the process of gaining knowledge.
Writing is a lonely job. Even if a writer socializes regularly, when he gets down to the real business of his life, it is he and his type writer or word processor. No one else is or can be involved in the matter.
The energy requirements for interstellar travel are so great that it is inconceivable to me that any creatures piloting their ships across the vast depths of space would do so only in order to play games with us over a period of decades. If they want to make contact, they would make contact; if not, they would save their energy and go elsewhere.
The lucky few who can be involved in creative work of any sort will be the true elite of mankind, for they alone will do more than serve a machine.
I prefer rationalism to atheism. The question of God and other objects-of-faith are outside reason and play no part in rationalism, thus you don't have to waste your time in either attacking or defending.
To those who are trained in science, creationism seems a bad dream, a sudden coming back to life of a nightmare, a renewed march of an Army of the Night risen to challenge free thought and enlightenment.
A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
