Quote

New ideas pass through three periods: 1) It can't be done. 2) It probably can be done, but it's not worth doing. 3) I knew it was a good idea all along!

There were some things that only time could cure. Evil men could be destroyed, but nothing could be done with good men who were deluded.
Arthur C. Clarke
Image
I can never look now at the Milky Way without wondering from which of those banked clouds of stars the emissaries are coming. If you will pardon so commonplace a simile, we have set off the fire alarm and have nothing to do but to wait. I do not think we will have to wait for long.
Arthur C. Clarke
Image
Whether we are based on carbon or on silicon makes no fundamental difference we should each be treated with appropriate respect.
Arthur C. Clarke
Image
Don't mess up the environment until you're quite sure what you're doing.
Arthur C. Clarke
Image
I have great faith in optimism as a guiding principle, if only because it offers us the opportunity of creating a self-fulfilling prophecy.
Arthur C. Clarke
Image
People go through four stages before any revolutionary development: 1. It's nonsense, don't waste my time. 2. It's interesting, but not important. 3. I always said it was a good idea. 4. I thought of it first.

What was more, they had taken the first step toward genuine friendship. They had exchanged vulnerabilities.
Arthur C. Clarke
Image
. . . Moon-Watcher felt the first faint twinges of a new and potent emotion. It was a vague and diffuse sense of envy--of dissatisfaction with his life. He had no idea of its cause, still less of its cure but discontent had come into his soul, and he had taken one small step toward humanity.
Arthur C. Clarke
Image
Perhaps no other year before or since 1984 has been awaited with such eager anticipation.
Arthur C. Clarke
Image
Before the current decade ends, fee-paying passengers will be experiencing suborbital flights aboard privately funded vehicles. . . . It won't be too long before bright young men and women set their eyes on careers in Earth orbit and say: I want to work 200 kilometers from home-straight up!
Arthur C. Clarke
Image
The Earth would only have to move a few million kilometers sunward-or starward-for the delicate balance of climate to be destroyed. The Antarctic icecap would melt and flood all low-lying land or the oceans would freeze and the whole world would be locked in eternal winter. Just a nudge in either direction would be enough.
Arthur C. Clarke
Image
I sometimes think that the universe is a machine designed for the perpetual astonishment of astronomers.
Arthur C. Clarke
Image
Utopia was here at last: its novelty had not yet been assailed by the supreme enemy of a ll Utopias - boredom.
Arthur C. Clarke
Image
I'm surprised at some technological development, and the realization that any sufficiently advanced technology is indistinguishable from magic. I think the CD-ROM is the best example of that. The idea of having a whole symphony, or opera, or novel in a little piece of plastic is pretty amazing.
Arthur C. Clarke
Image
It is not easy to see how the more extreme forms of nationalism can long survive when men have seen the Earth in its true perspective as a single small globe against the stars.
Arthur C. Clarke
Image
Attempting to define science fiction is an undertaking almost as difficult, though not so popular, as trying to define pornography... In both pornography and SF, the problem lies in knowing exactly where to draw the line.
Arthur C. Clarke

Science is the only religion of mankind.

Image
The space elevator will be built about 50 years after everyone stops laughing.

Image
We have to abandon the idea that schooling is something restricted to youth. How can it be, in a world where half the things a man knows at 20 are no longer true at 40 - and half the things he knows at 40 hadn't been discovered when he was 20?

I would defend the liberty of consenting adult creationists to practice whatever intellectual perversions they like in the privacy of their own homes but it is also necessary to protect the young and innocent.
