Alan Turing

Politics of secrecy hindered progress.

I am optimistic about the future.

Legacy is what we leave behind.

Humor in math: pi is irrational.

Understanding is the goal.

Art inspires innovation.

Peace is my wish.

Endless curiosity.

Computability limits knowledge.

Laughter heals.

Wisdom from failure.

The meaning of life is discovery.

I am fulfilled.

The original question, 'Can machines think?' I believe to be too meaningless to deserve discussion.

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 may hope that machines will eventually compete with men in all purely intellectual fields.

The extent to which we regard something as 'intelligent' depends on the extent to which it can surprise us.

The idea of a digital computer is a mathematical abstraction.

It is possible to invent a single machine which can be used to compute any computable sequence.

The 'logical completeness' of a universal machine is not in question.
