There is no belief, however foolish, that will not gather its faithful adherents who will defend it to the death.
Any teacher that can be replaced by a computer should be replaced by a computer.
Tell me why the stars do shine, Tell me why the ivy twines, Tell me what makes skies so blue, And I'll tell you why I love you. Nuclear fusion makes stars to shine, Tropisms make the ivy twine, Raleigh scattering make skies so blue, Testicular hormones are why I love you.
Properly read, the Bible is the most potent force for atheism ever conceived.
The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'
Life is a journey, but don't worry, you'll find a parking spot at the end.
Science is uncertain. Theories are subject to revision; observations are open to a variety of interpretations, and scientists quarrel amongst themselves. This is disillusioning for those untrained in the scientific method, who thus turn to the rigid certainty of the Bible instead. There is something comfortable about a view that allows for no deviation and that spares you the painful necessity of having to think.
My feeling is, quite simply, that if there is a God, He has done such a bad job that he isn't worth discussing.
Man's greatest asset is the unsettled mind.
Increasingly, our leaders must deal with dangers that threaten the entire world, where an understanding of those dangers and the possible solutions depends on a good grasp of science. The ozone layer, the greenhouse effect, acid rain, questions of diet and heredity. All require scientific literacy. Can Americans choose the proper leaders and support the proper programs if they themselves are scientifically illiterate? The whole premise of democracy is that it is safe to leave important questions to the court of public opinion - but is it safe to leave them to the court of public ignorance?
Never let your sense of morals get in the way of doing what's right.
To succeed, planning alone is insufficient. One must improvise as well.
In life, unlike chess, the game continues after checkmate.
Isn't it sad that you can tell people that the ozone layer is being depleted, the forests are being cut down, the deserts are advancing steadily, that the greenhouse effect will raise the sea level 200 feet, that overpopulation is choking us, that pollution is killing us, that nuclear war may destroy us - and they yawn and settle back for a comfortable nap. But tell them that the Martians are landing, and they scream and run.
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."
Democracy cannot survive overpopulation. Human dignity cannot survive it. Convenience and decency cannot survive it. As you put more and more people into the world, the value of life not only declines, but it disappears. It doesn't matter if someone dies.
It is not so much that I have confidence in scientists being right, but that I have so much in nonscientists being wrong.
They won't listen. Do you know why? Because they have certain fixed notions about the past. Any change would be blasphemy in their eyes, even if it were the truth. They don't want the truth; they want their traditions.
Intelligence is an accident of evolution, and not necessarily an advantage.
He always pictured himself a libertarian, which to my way of thinking means "I want the liberty to grow rich and you can have the liberty to starve". It's easy to believe that no one should depend on society for help when you yourself happen not to need such help.
I don't subscribe to the thesis, 'Let the buyer beware,' I prefer the disregarded one that goes, 'Let the seller be honest.'
If I am right, then (religious fundamentalists) will not go to Heaven, because there is no Heaven. If they are right, then they will not go to Heaven, because they are hypocrites.
While he lives, he must think; while he thinks, he must dream.
The intelligent man is never bored.
