Sayings by Alan Turing

The story of how it all came to be found out is a long and fascinating one, which I shall have to make into a short story one day, but haven't the time to tell you now.

1952 — From a letter to Norman Routledge about his impending legal troubles.

The activity of the intuition consists in making spontaneous judgements which are not the result of conscious trains of reasoning. These judgments are often but by no means invariably correct…

c. 1939 — On mathematical intuition and ingenuity, discussed in his 1939 doctoral thesis.

The idea of a 'thinking machine' has been considered by many, but the time for such a possibility is still far off.

Instead of trying to produce a programme to simulate the adult mind, why not rather try to produce one which simulates the child's?

We can only see a short distance ahead, but we can see plenty there that needs to be done.

Strange & Unusual Confirmed

A computer would deserve to be called intelligent if it could deceive a human into believing that it was human.

Mathematical reasoning may be regarded rather schematically as the exercise of a combination of two facilities, which we may call intuition and ingenuity.

The machine has a definite state at any moment, which is determined by the instructions it has received and by the results of its previous operations.

1936 — On Computable Numbers, with an Application to the Entscheidungsproblem
Strange & Unusual Unverifiable

It seems probable that once the machine thinking method had started, it would not take long to outstrip our feeble powers and would take control.

No, I'm not interested in developing a powerful brain. All I'm interested in is a moderately trained brain. The kind that would be useful in daily life.

The extent to which we regard thinking as a function of the brain rather than the entire body is very much a matter of taste.

The power of the human mind is limited, but the power of the machine is infinite.

Unknown — Attributed, common theme in his discussions on AI.

A computer is a universal machine, capable of carrying out any calculation that can be performed by a human.

The main problem with artificial intelligence is that it is too easy to make a machine that can do what we want it to do, but too hard to make a machine that can do what we don't want it to do.

Unknown — Attributed, often cited in discussions of AI control and ethics.
Strange & Unusual Unverifiable

The true nature of intelligence is not to be found in the ability to solve problems, but in the ability to ask the right questions.

Unknown — Attributed, philosophical musing.

Machines take me by surprise very often.

The computer is a tool, and like any tool, it can be used for good or for evil.

Unknown — Attributed, general statement on technology.

The human brain is a very complex machine, but it is still a machine.
