“The Exclusion Principle is laid down purely for the benefit of the electrons themselves, who might be corrupted (and become dragons or demons) if allowed to associate too freely.”

Instead of trying to produce a programme to simulate the adult mind, why not rather try to produce one which simulates the child’s? If this were then subjected to an appropriate course of education one would obtain the adult brain.

I’m afraid that the following syllogism may be used by some in the future. Turing believes machines think Turing lies with men Therefore machines do not think Yours in distress, Alan.

My little computer said such a funny thing this morning.

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.

Do you know why people like violence? It is because it feels good. Humans find violence deeply satisfying. But remove the satisfaction, and the act becomes hollow.

We are not interested in the fact that the brain has the consistency of cold porridge.

These disturbing phenomena [Extra Sensory Perception] seem to deny all our scientific ideas. How we should like to discredit them! Unfortunately the statistical evidence, at least for telepathy, is overwhelming.

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”.

Machines take me by surprise with great frequency.

A very large part of space-time must be investigated, if reliable results are to be obtained.

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

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

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

No, I’m not interested in developing a powerful brain.

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

Each of us deserves the freedom to pursue our own version of happiness. No one deserves to be bullied.

There are only two kinds of freedom in the world; the freedom of the rich and powerful, and the freedom of the artist and the monk who renounces possessions.

They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.

Freedom is difficult things.

Whoever would overthrow the liberty of a nation must begin by subduing the freeness of speech.

Blind belief in authority is the greatest enemy of truth.

I freely chose the kind of life I led because I was convinced that a woman has as much right as a man to live the way she does if she does no actual harm to society.

Every day brings a chance to live free of regret and with as much joy, fun, and laughter as you can stand.
