If a machine is expected to be infallible, it cannot also be intelligent.

Science is a differential equation. Religion is a boundary condition.

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

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.

Sometimes it is the people no one imagines anything of who do the things that no one can imagine.

One day ladies will take their computers for walks in the park and tell each other, "My little computer said such a funny thing this morning".

A man provided with paper, pencil, and rubber, and subject to strict discipline, is in effect a universal machine.
