Smart Quotes (33 quotes)

[T]here are some common animal behaviors that seem to favor the development of intelligence, behaviors that might lead to brainy beasts on many worlds. Social interaction is one of them. If you're an animal that hangs out with others, then there's clearly an advantage in being smart enough to work out the intentions of the guy sitting next to you (before he takes your mate or your meal). And if you're clever enough to outwit the other members of your social circle, you'll probably have enhanced opportunity to breed..., thus passing on your superior intelligence. ... Nature—whether on our planet or some alien world—will stumble into increased IQ sooner or later.
Seth Shostak, Alex Barnett, Cosmic Company: the Search for Life in the Universe (2003), 62 & 67.

A person is smart. People are dumb ... Fifteen hundred years ago everybody knew the Earth was the center of the universe. Five hundred years ago, everybody knew the Earth was flat, and fifteen minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow.

Character Agent K in movie Men in Black(1997), screen story and screenplay by Ed Solomon. Quoted in George Aichele, Culture, Entertainment and the Bible (2000), 26. In a footnote, from the post-movie novel by Steve Perry, Men in Black (1997), 66, is added, 'Yeah. A hundred years from now, whoever is here will probably pee themselves laughing at what we believe.'

All the summer long is the swallow a most instructive pattern of unwearied industry and affection; for, from morning to night, while there is a family to be supported, she spends the whole day in skimming close to the ground, and exerting the most sudden turns and quick evolutions. Avenues, and long walks under hedges, and pasture-fields, and mown meadows where cattle graze, are her delight, especially if there are trees interspersed; because in such spots insects most abound. When a fly is taken a smart snap from her bill is heard, resembling the noise at the shutting of a watch case; but the motion of the mandibles are too quick for the eye.
In Letter to Daines Barrington (29 Jan 1774), in In The Natural History and Antiquities of Selborne (1789), 169-170.

Anyone who, as a geologist, has been alone and intimate with nature for many years will find himself increasingly often and more clearly placed in a dialogue, in which the other always turns out to be the smarter one.
From Einfükrung in die Geologie: Ein Lehrbuch der Inneren Dynamik (1936), 2. As auto-translated by Google from the original German, “Wer als Geologe lange Jahre mit der Natur allein und intim verkehrt, findet sich immer häufiger und deutlicher in eine Zwiesprache versetzt, bei welcher sich der andere stets als der Gescheitere herausstellt.” Epigraph in R. W. van Bemmelen, 'The Scientific Character of Geology', The Journal of Geology (Jul 1961), 69, No. 4, 453.

As kids we started smoking because we thought it was smart. Why don't we stop smoking for the same reason?

At about the age of sixteen, I began to feel uneasy. My confidence in adults began to be shaken. They were not smarter than us kids. They just had fixed ideas and stuck to them even if they disagreed among themselves. They were dragging us along a road to an unknown destination; they had no goal, just something to escape from: nature. … It was better to begin to look for a safer, side track. I began to feel like a prisoner calmly preparing to jump off a train that was on a wrong track.
In Ch. 1, 'Farewell to Civilization', Fatu-Hiva (1974), 6.

First you guess. Don’t laugh, this is the most important step. Then you compute the consequences. Compare the consequences to experience. If it disagrees with experience, the guess is wrong. In that simple statement is the key to science. It doesn’t matter how beautiful your guess is or how smart you are or what your name is. If it disagrees with experience, it’s wrong.
As condensed in Florentin Smarandache, V. Christianto, Multi-Valued Logic, Neutrosophy, and Schrodinger Equation? (2006), 73 & 160 (footnote), paraphrasing from Lecture No. 7, 'Seeking New Laws', Messenger Lectures, Cornell (1964). The original verbatim quote, taken from the transcript is elsewhere on the Richard Feynman Quotations webpage, beginning: “In general, we look for a new law…”.

For a smart material to be able to send out a more complex signal it needs to be nonlinear. If you hit a tuning fork twice as hard it will ring twice as loud but still at the same frequency. That’s a linear response. If you hit a person twice as hard they’re unlikely just to shout twice as loud. That property lets you learn more about the person than the tuning fork. - When Things Start to Think, 1999.

I don’t think America can just drill itself out of its current energy situation. We don’t need to destroy the environment to meet our energy needs. We need smart, comprehensive, common-sense approaches that balance the need to increase domestic energy supplies with the need to maximize energy efficiency.
Statement on New Long-Term Energy Solutions (22 Mar 2001). In Bill Adler (ed.), The Wit and Wisdom of Ted Kennedy (2011).

I grew up in love with science, asking the same questions all children ask as they try to codify the world to find out what makes it work. “Who is the smartest person in the world?” and “Where is the tallest mountain in the world?” turned into questions like, “How big is the universe?” and “What is it that makes us alive?”
In Introduction to Isaac Asimov and Jason A. Shulman (eds.), Isaac Asimov’s Book of Science and Nature Quotations (1988), xix.

I recognize that many physicists are smarter than I am—most of them theoretical physicists. A lot of smart people have gone into theoretical physics, therefore the field is extremely competitive. I console myself with the thought that although they may be smarter and may be deeper thinkers than I am, I have broader interests than they have.

I'm not smart. I try to observe. Millions saw the apple fall but Newton was the one who asked 'why.'
Quoted in New York Post (24 Jun 1965). In Alfred J. Kolatch, Great Jewish Quotations (1996), 38-39.

If it [a hypothesis] disagrees with experiment, it’s wrong. In that simple statement, is the key to science: it doesn’t make any difference how beautiful your guess is; it doesn’t make any difference how smart you are, who made the guess, or what his name is—if it disagrees with experiment, it’s wrong; that’s all there is to it.
Verbatim from Lecture No. 7, 'Seeking New Laws', Messenger Lectures, Cornell, (1964) in video and transcript online at caltech.edu website.

It is the responsibility of scientists never to suppress knowledge, no matter how awkward that knowledge is, no matter how it may bother those in power; we are not smart enough to decide which pieces of knowledge are permissible, and which are not. …

Sometimes seen in recent publications attributed to Mark Twain, for example, in Thomas R. Rosebrough and ‎Ralph G. Leverett Transformational Teaching in the Information Age (2011), 71. Also seen as “If teaching were just telling then we’d all be so smart we couldn’t stand up.” Webmaster has tried, but has not yet been able to find a primary source in Twain’s writings, and so believes “Anonymous” is the most likely source.

This is our fifth White House Science Fair. And every year, I walk out smarter than I walked in, because … these young scientists and engineers teach us something beyond the specific topics that they’re exploring. They teach us how to question assumptions; to wonder why something is the way it is, and how we can make it better. And they remind us that there’s always something more to learn, and to try, and to discover, and to imagine—and that it’s never too early, or too late to create or discover something new.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
