25 Linus Pauling Quotes on Science, Peace, and the Power of Ideas
Linus Carl Pauling (1901-1994) was an American chemist, biochemist, and peace activist who remains one of only two people to have received two unshared Nobel Prizes — the Nobel Prize in Chemistry in 1954 and the Nobel Peace Prize in 1962. Born in Portland, Oregon, Pauling's intellectual curiosity was evident from childhood, and he went on to become one of the most influential scientists of the twentieth century.
Pauling's work on the nature of the chemical bond, published in his landmark 1939 book of the same name, transformed chemistry by applying quantum mechanics to molecular structure. He introduced the concepts of electronegativity and orbital hybridization, developed rules for predicting molecular geometry, and laid the groundwork for modern structural chemistry.
In biology, Pauling made groundbreaking contributions to understanding protein structure, identifying the alpha helix as a fundamental structural motif. His discovery that sickle-cell anemia is caused by an abnormal hemoglobin molecule established the concept of molecular disease. He narrowly missed discovering the structure of DNA, a race ultimately won by Watson and Crick.
Pauling's activism against nuclear weapons testing in the 1950s and 1960s was courageous and consequential. Despite facing investigation by Senator McCarthy's committees and having his passport revoked, Pauling persisted in his campaign, which contributed directly to the Partial Nuclear Test Ban Treaty of 1963. His Nobel Peace Prize recognized this tireless advocacy.
In later life, Pauling became a controversial advocate for orthomolecular medicine and high-dose vitamin C therapy. While some of these claims remain debated, his underlying conviction — that nutrition and molecular-level interventions could prevent disease — has found increasing support in modern nutritional science. Pauling's breadth of achievement across science, medicine, and peace advocacy is unmatched in modern history.
Here are 25 quotes from Linus Pauling that capture his views on science, creativity, peace, and the responsibility of the intellectual life.

Key Achievements and Episodes
The Only Person to Win Two Unshared Nobel Prizes
Pauling is the only individual to have won two unshared Nobel Prizes. He received the Nobel Prize in Chemistry in 1954 for his research on the nature of the chemical bond, and the Nobel Peace Prize in 1962 for his campaign against nuclear weapons testing. His work on chemical bonding, published in The Nature of the Chemical Bond (1939), is one of the most influential chemistry books ever written and introduced the concepts of orbital hybridization and electronegativity.
The Race for DNA
In 1953, Pauling proposed a triple-helix structure for DNA that turned out to be wrong — one of the few major errors in his career. Watson and Crick, racing to solve the structure at Cambridge, were terrified that Pauling would discover his mistake and beat them to the correct answer. The error partly resulted from Pauling being denied a passport by the U.S. State Department due to his political activism, preventing him from attending a conference where he might have seen Rosalind Franklin's crucial X-ray data.
Campaigning Against the Bomb
After World War II, Pauling became one of the most prominent scientists to speak out against nuclear weapons. He collected signatures from over 11,000 scientists worldwide on a petition calling for an end to nuclear testing, which he presented to the United Nations in 1958. His activism drew accusations of Communist sympathies during the McCarthy era, and his passport was repeatedly confiscated. The Partial Nuclear Test Ban Treaty was signed on the day the Nobel Peace Prize committee announced his award in 1963.
On Science and Discovery
Linus Pauling's contributions to chemistry fundamentally transformed our understanding of the chemical bond and the structure of molecules, earning him the Nobel Prize in Chemistry in 1954 for his research into the nature of the chemical bond and its application to the elucidation of complex substances. His landmark 1931 paper on the nature of the chemical bond introduced the concepts of orbital hybridization and resonance, which explained the geometry of molecules in terms of quantum mechanics and revolutionized both organic and inorganic chemistry. His 1939 textbook "The Nature of the Chemical Bond" became one of the most cited scientific books of the twentieth century, influencing generations of chemists and remaining in print for decades. Pauling's 1951 discovery of the alpha helix and beta sheet structures of proteins, published with Robert Corey, was a crucial step toward understanding protein folding and function. These science and discovery quotes from Pauling reflect the creative boldness of a chemist who believed that generating many ideas — and rigorously testing each one — is the surest path to breakthrough innovation.
"The best way to have a good idea is to have lots of ideas."

On Peace and Responsibility
Pauling's commitment to peace and nuclear disarmament earned him the Nobel Peace Prize in 1962, making him one of only two individuals — alongside Marie Curie — to receive Nobel Prizes in two different categories without sharing either award. His activism began after the atomic bombings of Hiroshima and Nagasaki in August 1945, and he became one of the most prominent scientific voices against nuclear weapons testing, circulating a petition signed by over 11,000 scientists worldwide calling for an end to atmospheric nuclear tests. This campaign contributed directly to the Partial Nuclear Test Ban Treaty signed in 1963, the same year the Nobel Committee awarded him the Peace Prize. Pauling's anti-nuclear activism drew fierce opposition during the McCarthy era, and the US State Department revoked his passport in 1952, preventing him from attending scientific conferences abroad — including a 1952 Royal Society meeting where he might have seen Rosalind Franklin's DNA X-ray data before Watson and Crick. These peace and responsibility quotes from Pauling embody the conviction that scientists have a moral obligation to prevent the destructive misuse of their discoveries.
"I believe that there will never again be a great world war — a war in which the terrible weapons involving nuclear fission and nuclear fusion would be used."
From his Nobel Peace Prize lecture (1963)
"Every human being should work for the elimination of war and the development of world peace."
From "No More War!" (1958)
"The scientist has a responsibility not only to discover new truths but also to consider the consequences of those discoveries."
Widely attributed to Linus Pauling
"I believe that every person in the world has a duty to work to prevent the outbreak of a devastating nuclear war."
From his peace activism
"The world progresses, year by year, century by century, as the members of the younger generation find out what was wrong among the things that their elders said."
Widely attributed to Linus Pauling
"Do unto others twenty percent better than you would expect them to do unto you, to correct for subjective error."
Widely attributed to Linus Pauling
On Creativity and Thinking
Pauling's approach to scientific problems was characterized by a remarkable ability to visualize molecular structures in three dimensions and to apply quantum mechanical principles to chemical bonding with intuitive clarity. At the California Institute of Technology, where he joined the faculty in 1922 and remained for over four decades, he trained a generation of chemists and molecular biologists who went on to transform their fields. His 1953 proposal of a triple-helix structure for DNA, though ultimately incorrect, demonstrated his willingness to take risks and publish bold hypotheses that could be tested and refined by the scientific community. Pauling's concept of molecular disease, introduced in his 1949 paper identifying sickle cell anemia as caused by a single amino acid change in hemoglobin, was the first demonstration that a human disease could be traced to a specific molecular defect. These creativity and thinking quotes from Pauling capture the intellectual fearlessness of a scientist who understood that wrong ideas, rapidly tested and discarded, are the stepping stones to correct ones.
"I recognized that I had the ability to think about scientific problems in terms of models."
From an interview about his scientific method
"The first thing is to acquire knowledge. Then you have to use your imagination."
Widely attributed to Linus Pauling
"Do not let either the medical authorities or the politicians mislead you. Find out what the facts are, and make your own decisions about how to live a happy life."
Widely attributed to Linus Pauling
"I think that to fully enjoy life you need to be willing to think about things in new ways."
Widely attributed to Linus Pauling
On Health and Life
Pauling's later years were devoted to the controversial promotion of orthomolecular medicine, particularly the use of high-dose vitamin C for preventing and treating cancer and the common cold. His 1970 book "Vitamin C and the Common Cold" became a bestseller and popularized the concept of megavitamin therapy, though many of his specific claims about vitamin C were not supported by subsequent controlled clinical trials. He founded the Linus Pauling Institute at Stanford in 1973, later relocated to Oregon State University, to research the role of micronutrients in health and disease — an institution that continues to conduct important research on nutrition and healthy aging. Pauling died on August 19, 1994, at the age of ninety-three at his ranch in Big Sur, California, having remained scientifically active and publicly outspoken until the end. These health and life quotes from Pauling reflect the same passionate conviction that characterized all his work — the belief that scientific knowledge, applied with courage and good faith, holds the key to human well-being.
"Optimum nutrition is the medicine of tomorrow."
Widely attributed to Linus Pauling
"I have something that I call my Golden Rule. It goes something like this: 'Do unto others twenty-five percent better than you expect them to do unto you.' The twenty-five percent is for error."
Widely attributed to Linus Pauling
"Everyone should know that most cancer research is largely a fraud."
Widely attributed to Linus Pauling
"I believe that you can, by taking some simple and inexpensive measures, lead a longer life and extend your years of well-being."
From "How to Live Longer and Feel Better" (1986)
"I made my own way, doing with my life what I wanted to do and what interested me."

Frequently Asked Questions about Linus Pauling Quotes
What are Linus Pauling's most famous quotes about science and discovery?
Linus Pauling, the only person to win two unshared Nobel Prizes (Chemistry in 1954 and Peace in 1962), produced some of the most quotable lines in 20th-century science. His most famous statement is "The best way to have a good idea is to have lots of ideas," reflecting his prodigious creativity across chemistry, biology, and peace activism. He also said "Satisfaction of one's curiosity is one of the greatest sources of happiness in life," linking scientific inquiry to personal fulfillment. About the nature of scientific progress, he observed "Science is the search for truth — it is not a game in which one tries to beat his opponent, to do harm to others." Pauling's work on the nature of the chemical bond — his 1939 book of that title is one of the most influential chemistry texts ever written — revolutionized understanding of how atoms join together. He was also a pioneer of molecular biology, correctly predicting the alpha helix structure of proteins and narrowly missing the discovery of DNA's structure (he proposed an incorrect triple-helix model in 1953).
What did Linus Pauling say about peace and nuclear disarmament?
Pauling's peace activism, which earned him the Nobel Peace Prize in 1962, was driven by his understanding of nuclear weapons' destructive potential. He said "Every human being has the right to live in a world that is free from the threat of nuclear war" and led a petition signed by over 11,000 scientists calling for an end to nuclear testing. His activism came at great personal cost — during the McCarthy era, the State Department revoked his passport (nearly preventing him from attending the Nobel ceremony in Stockholm), and he was branded a communist sympathizer. He responded "No one should be compelled to contribute, against his conscience, to the development of nuclear weapons." Pauling's efforts directly contributed to the 1963 Partial Nuclear Test Ban Treaty, which banned atmospheric nuclear testing. He wrote "I believe that there will never be a nuclear war. I believe that the will for peace on the part of the people of the world is so great that the governments will have to accept it." His dual legacy as both a groundbreaking scientist and a peace advocate remains unmatched.
What was Linus Pauling's controversial stance on vitamin C?
In his later years, Pauling became a passionate advocate for high-dose vitamin C as a treatment for the common cold and cancer, publishing "Vitamin C and the Common Cold" in 1970. He said "Do not let either the medical authorities or the politicians mislead you. Find out what the facts are, and make your own decisions about how to live a happy life and how to work for a better world." He took 18,000 milligrams of vitamin C daily — far above the recommended dose — and claimed it could extend life by decades. While some of his specific claims about vitamin C have not been supported by subsequent research, his broader point about the importance of nutrition in health was ahead of its time. Pauling's vitamin C advocacy is often cited as a cautionary tale about how even brilliant scientists can fall prey to confirmation bias in areas outside their core expertise. He said "The best way to have a good idea is to have lots of ideas, and then to discard the bad ones" — advice that some argue he failed to follow regarding his vitamin theories. He died in 1994 at age 93.
