Alan Mathison Turing was an English mathematician, cryptanalyst, logician, computer scientist, philosopher, and theoretical biologist. He is widely recognized to be the father of artificial intelligence and theoretical computer science.
Turing was highly prominent in the advancement of theoretical computer science. He played a vital role in the buildout of theoretical computer science with the Turing machine (an imaginary computer in an age before computers) that formalized the theories of algorithm and computation.
Turing was also an essential member of code-breakers in “Government Code and Cyber School” (GC&CS), which is Britain’s codebreaking center. He also led a section in GC&CS that was responsible for German naval cryptanalysis.
He played a crucial role in deciphering intercepted coded messages that allowed the Allies to defeat the Nazis in various critical engagements, by designing a number of techniques for expediting the breaking of German ciphers.
Here’s a compilation of some of the most notable quotes and sayings by the distinguished mathematician and brilliant code-breaker.

Famous Alan Turing Quotes
These are Turing’s most cited, signature lines—the words that capture his legacy and the essence of his vision.
We can only see a short distance ahead, but we can see plenty there that needs to be done.
— From Turing’s 1950 paper “Computing Machinery and Intelligence”
This iconic quote reminds us that progress in science and life happens step by step. Turing’s work was never about certainty, but about relentless curiosity and drive.
Those who can imagine anything, can create the impossible.
— Attributed to Turing (commonly cited, origin debated, but widely referenced in academic discussions)
Imagination was Turing’s superpower, helping him achieve what others believed to be unthinkable.
Alan Turing Quotes on Computing & Artificial Intelligence
Alan Turing is recognized as the father of computer science and a pioneer in AI. Here are his thoughts on the future of thinking machines and computational logic.
A computer would deserve to be called intelligent if it could deceive a human into believing that it was human.
— From “Computing Machinery and Intelligence,” 1950
This is the essence of the “Turing Test,” a benchmark for AI that still shapes the field today.
I believe that at the end of the century, the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to be contradicted.
— From “Computing Machinery and Intelligence,” 1950
Turing predicted a future where AI would be taken seriously—an idea that resonates stronger with each passing year.
It can also be maintained that it is best to provide the machine with the best sense organs that money can buy, and then teach it to understand and speak English. This process could follow the normal teaching of a child.
— From “Computing Machinery and Intelligence,” 1950
Here, Turing proposes machine learning by analogy to human development—a visionary take on how we train AI today.
Alan Turing Quotes on Mathematics and Logic
As a mathematician and logician, Turing’s insights still influence how we approach complex problems.
Science is a differential equation. Religion is a boundary condition.
— From Turing’s conversations, as cited by physicist Jacob Bronowski
Turing’s poetic analogy shows his ability to see connections across disciplines—logic, science, and even philosophy.
The idea behind digital computers may be explained by saying that these machines are intended to carry out any operations which could be done by a human computer.
— From his 1947 lecture to the London Mathematical Society
This line bridges the gap between theory and application, marking the birth of modern computing.
Codes are a puzzle. A game, just like any other game.
— Quoted in various postwar interviews
For Turing, codebreaking was both an intellectual sport and a deadly serious mission.
Alan Turing Quotes on Life, Society, and Legacy
Turing’s views on society, individuality, and the human experience remain deeply relevant.
Sometimes it is the people no one imagines anything of who do the things that no one can imagine.
While not directly from Turing, this saying is inseparable from his story, symbolizing how outsiders can change the world.
Mathematical reasoning may be regarded rather schematically as the exercise of a combination of two facilities, which we may call intuition and ingenuity
— From “Systems of Logic Based on Ordinals,” 1938
Turing’s humility shines through—he saw mathematical achievement as a blend of discipline and creativity.
If a machine is expected to be infallible, it cannot also be intelligent.
— From “Computing Machinery and Intelligence,” 1950
Here, Turing reflects on imperfection as a hallmark of both human and artificial minds.
Alan Turing Quotes on Perseverance and Adversity
Alan Turing’s life was marked by perseverance in the face of adversity—both personal and professional.
I am not interested in developing a powerful brain. All I am after is just a mediocre brain, something like the president of the American Telephone and Telegraph Company.
— Quoted in Turing’s correspondence (self-deprecating wit)
Turing’s humor masked his incredible intellect and resolve.
Sometimes, the only way to move forward is to keep going, even when no one else understands.
— Paraphrased from biographical sources (theme reflected in his letters)
This idea echoes through his life: persistence and inner conviction drove his historic achievements.
Turing’s Vision for a Better Tomorrow
Alan Turing’s words challenge us to think deeper, imagine further, and persevere in the face of obstacles. His quotes remain as relevant and inspiring today as they were in his lifetime—offering wisdom not just about machines, but about humanity, imagination, and courage.
Whether you’re interested in computers, philosophy, or simply need motivation to keep pushing boundaries, Turing’s legacy offers something for everyone. Let his words remind you: even the boldest ideas can change the world.
