«However life started, once established, it persisted for over 3.5 billion years and evolved from microbial slime to the sophistication of human civilization.»

David C. Catling

«When the time is ripe for certain things, these things appear in different places in the manner of violets coming to light in early spring.»

Farkas Bolyai

«Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation.»

Richard Dawkins

«Am I right in suggesting that ordinary life is a mean between these extremes, that the noble man devotes his material wealth to lofty ends, the advancement of science, or art, or some such true ideal; and that the base man does the opposite by concentrating all his abilities on the amassing of wealth?'»

Aleister Crowley

«It's cloaked in cultural mumbo jumbo, but I assure you that it is very hard science.»

Jonathan Maberry

«All sciences are vain and full of errors that are not born of Experience, the mother of all Knowledge.»

Leonardo da Vinci

«The truth of our faith becomes a matter of ridicule among the infidels if any Catholic, not gifted with the necessary scientific learning, presents as dogma what scientific scrutiny shows to be false.»

Thomas Aquinas

«The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.»

Carl Sagan

«Human beings, viewed as behaving systems, are quite simple. The apparent complexity of our behavior over time is largely a reflection of the complexity of the environment in which we find ourselves.»

Herbert A. Simon

«Science began to be irrelevant when mankind were protected from nature instead of protecting nature from mankind.»

Kgotso Lebogang Seroka

«...evolution is not a religious tenet, to which one swears allegiance or belief as a matter of faith.. It is a factual reality of the empirical world. Just as one would not say 'I believe in gravity," one should not proclaim 'I believe in evolution.»

Michael Shermer

«And although I have seen nothing but black crows in my life, it doesn't mean that there's no such thing as a white crow. Both for a philosopher and for a scientist it can be important not to reject the possibility of finding a white crow. You might almost say that hunting for 'the white crow' is science's principal task.»

Jostein Gaarder

«Of course you know. You're brilliant. Everyone says so."»

Don DeLillo

«Imagination is cheap as long as you don't have to worry about the details.»

Daniel C. Dennett

«A mathematician believes that describing the speed of Mercury with equations amounts to science.»

Bill Gaede

«Why has not anyone seen that fossils alone gave birth to a theory about the formation of the earth, that without them, no one would have ever dreamed that there were successive epochs in the formation of the globe.»

Georges Cuvier

«An expert is a person who has made all the mistakes that can be made in a very narrow field.»

Niels Bohr

«I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer. And perhaps with better cause, for while a buck pulled down by wolves can be replaced in two or three years, a range pulled down by too many deer may fail for replacement in as many decades»

Aldo Leopond

«Then they wondered if there were men in the stars. Why not? And as creation is harmonious, the inhabitants of Sirius ought to be huge, those of Mars middle-sized, those of Venus very small. Unless it is the same everywhere. There are businessmen, police up there; people trade, fight, dethrone their kings.»

Gustave Flaubert

«We know that energy can not be created nor destroyed but can be changed in it's form. If it can not be formed then it can not exist. We may not exist.»

Mohammed Ali

«We should be cautiously open to the spiritual and non-rational, and skeptical of the more invisible magical thinking—what we might call “magical reason”—pervading secular thought and experience in modern society. Science and technology are for most people a new religion, and their orthodoxies are believed with the same fervor.»

David Watson

«Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter.»

Eric Raymond

«The literature [Nobel] laureate of this year has said that an author can do anything as long as his readers believe him.»

Sune Bergström

«Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy.»

Joseph Fourier

«Science asymptotically approaches reality»

Philip Plait

«It Begins with skepticism. The history of human folly, and our own susceptibility to illusions and fallacies, tell us that men and women are fallible.»

Steven Pinker

«Life is something that no one can teach you,You have to learn it.»

Jerril Thomas Abraham

«We have not been created out of nothing, but from primeval "ur-matter," atoms formed billions of years ago that have for a brief while been gathered into collections that think they are us.»

Frank Close

«He rises a copy of a poster. On the left is a quote from The New York Times dated October 9, 1903. It says,'The flying machine which will really fly might be evolved by the combined and continuous efforts of mathematicians in from one million to ten million years'. On the right is a quote from Orville Wright's diary, dated October 9, 1903. 'We started assembly today' it says.»

Joel Garreau

«Ã‰ claro que não há um único gene, mas há algo infinitamente mais enaltecedor e magnífico: toda uma naturza humana, flexivelmente pré-ordenada em nossos cromossomos e indiossincrática de cada um de nós. Todo mundo tem uma única e distina natureza endógena. Um self.»

Matt Ridley
