Science Quotes

Asimov, Jacob Bronowski, Einstein, Arthur Eddington and Carl Sagan lead the page. The most-sourced writer is Henri Poincaré, with several passages from Science and Hypothesis (1901) and The Value of Science (1905), including the one about doubting everything and believing everything being two equally convenient ways to avoid thinking.

Two entries are flagged. “Etymology is a science in which vowels signify nothing at all, and consonants very little” is credited to Voltaire as disputed, and the notes cite two scholarly articles on where the saying comes from. “Mathematics is the key and door to the sciences” is credited to Galileo and flagged misattributed.

Random quote on Science

Most quoted on science:

... it really gets to this idea — how science asks us to learn about organisms, traditional knowledge asks us to learn from them.

Robin Wall Kimmerer Interview on the On Being podcast (2022)

I was an atheist, finding no reason to postulate the existence of any truths outside of mathematics, physics and chemistry. But then I went to medical school, and encountered life and death issues at the bedsides of my patients. Challenged by one of those patients, who asked "What do you believe, doctor?", I began searching for answers.

Francis Collins

A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable. We are all fallible, even leaders. But however clear it is that criticism is necessary for progress, governments tend to resist.

Carl Sagan Billions and Billions: Thoughts on Life and Death at the Brink of the Millenium (1997)

Science, dimly perceiving the truth, may find Bacteria and other infinitesimals in the human body, and see in them but occasional and abnormal visitors to which diseases are attributed. Occultism -- which discerns a life in every atom and molecule, whether in a mineral or human body, in air, fire or water -- affirms that our whole body is built of such lives, the smallest bacteria under the microscope being to them in comparative size like an elephant to the tiniest infusoria.

Helena Blavatsky

Science, by itself, has no moral dimension. The drug which cures when taken in small doses may kill when taken in excess. The nuclear energies that produce cheap electrical power when harnessed in a reactor may kill when abruptly released in a bomb. Thus, it does not make sense to ask a scientist whether his poison or his nuclear energy is “good” or “bad” for mankind.

Wernher von Braun

...when I started doing chemistry, I did it the way I fished – for the excitement, the discovery, the adventure, for going after the most elusive catch imaginable in uncharted seas.

Karl Barry Sharpless

The men in the laboratory [...] cannot be said to observe the actual objects of their curiosity at all.[...] The sense data on which the propositions of modern science rest are, for the most part, little photographic spots and blurs, or inky curved lines on paper.[...] What is directly observable is only a sign of the "physical fact"; it requires interpretation to yield scientific propositions.

Susanne Langer Philosophy in a New Key (1942)

He who is ignorant of Motion, says Aristotle, is necessarily ignorant of all natural things. ...Not only was he entirely in the dark respecting the Laws, he was completely wrong in his conception of the nature of Motion. ...He thought that every body in motion naturally tends to rest.

George Henry Lewes Aristotle: a Chapter from the History of Science (1864)

There was an ape in the days that were earlier,
Centuries passed and his hair became curlier;
Centuries more gave a thumb to his wrist—
Then he was a MAN and a Positivist.

Mortimer Collins

The Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter.

Pope Pius XII

I admonish you not to reject the method of experiment, but according as your power permits, to follow it without prejudice. For every experiment is like a weapon which must be used according to its peculiar power, as a spear to thrust, a club to strike, so also is it with experiments.

Paracelsus

The main object of the work was to present such a survey of the advances already made in physical knowledge, and of the mode in which they have been made, as might serve as a real and firm basis for our speculations concerning the progress of human knowledge, and the processes by which sciences are formed.

William Whewell History of the Inductive Sciences (1837)

Said the little Eohippus,
"I am going to be a horse,
And on my middle fingernails
To run my earthly course!
* * *
I'm going to have a flowing tail!
I'm going to have a mane!
I'm going to stand fourteen hands high
On the Psychozoic plain!"

Charlotte Perkins Gilman

I recognize nothing that is not material. In physics, chemistry and biology I see only mechanics. The Universe is nothing but an infinite and complex mechanism. Its complexity is so great that it borders on randomness, giving the illusion of free will.

Konstantin Tsiolkovsky

The history of science familiarizes us with the ideas of evolution and the continuous transformation of human things... It shows us that if the accomplishments of mankind as a whole are grand, the contributions of each is small.

George Sarton

The notion of "system" has gained central importance in contemporary science, society and life. In many fields of endeavor, the necessity of a "systems approach" or "systems thinking" is emphasized, new professions called "systems engineering," "systems analysis" and the like have come into being, and there can be little doubt that this this concept marks a genuine, necessary, and consequential development in science and world-view.

Ervin László Introduction to Systems Philosophy (1972)

I do not want to discuss evolution in such depth, however, only touch on it from my own perspective: from the moment when I stood on the Serengeti plains holding the fossilized bones of ancient creatures in my hands to the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back. You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.

Jane Goodall Reason for Hope: a Spiritual Journey (2000)

Can all that optics teach, unfold
Thy form to please me so,
As when I dreamt of gems and gold
Hid in thy radiant bow?
When Science from Creation's face
Enchantment's veil withdraws,
What lovely visions yield their place
To cold material laws!
And yet, fair bow, no fabling dreams,
But words of the Most High,
Have told why first thy robe of beams
Was woven in the sky.

Thomas Campbell Theodric: A Domestic Tale; and Other Poems (1825)

Could it be, nevertheless, that Einstein's theory is wrong? Might it be necessary to modify it—to find a new theory of gravity that can explain both the stronger gravity and the apparent antigravity being observed today—rather than simply throwing in invisible things to make the standard model work?

John Moffat Reinventing Gravity (2008)

Scanning the past millennia of human achievement reveals just how much has been achieved during the last three hundred years since Newton set in motion the effective mathematization of Nature. We found that the world is curiously adapted to a simple mathematical description. It is enigma enough that the world is described by mathematics; but by simple mathematics, of the sort that a few years energetic study now produces familiarity with, this is an enigma within an enigma.
