The Government are very keen on amassing statistics.  They collect them, add them, raise them to the nth power; take the cube root and prepare wonderful diagrams.  But you must never forget that every one of these figures comes in the first instance from the village watchman who puts down what he damn well pleases.

Those that can make you believe absurdities can make you commit atrocities.

Writing is like prostitution. 
First you do it for the love of it,
Then you do it for a few friends,
And finally you do it for money.

The fact that stares one in the face is that people of the greatest sincerity and of all levels of intelligence differ and have always differed in their religious beliefs.  Since at most one faith can be true, it follows that human beings are extremely liable to believe firmly and honestly in something untrue in the field of revealed religion.  One would have expected this obvious fact to lead to some humility, to some thought that however deep one's faith, one may conceivably be mistaken.  Nothing is further from the believer, any believer, than this elementary humility.  All in his power ... must have his faith rammed down their throats.  In many cases children are indeed indoctrinated with the disgraceful thought that they belong to the one group with superior knowledge who alone have a private wire to the office of the Almighty, all others being less forturnate than they themselves.

Intuition is the result of twenty years of experience.

The trouble with doing something right the first time is that nobody appreciates how difficult it was!

I myself have not learned big things in my own research.  I'm not a Watson or a Crick or a Weinberg, for that matter.  I've learned small things.  But to learn something one day that nobody ever knew before is something that, I think, everyone should have a chance to do.

In any experiment, regardless of the result, you can never know what really happened.

"I symbol process, therefore I think" is putting Descartes before the horse.

In the 15th Century,
   the Question was
"How many angels can dance
   on the head of a pin?"

In the 20th Century,
   the question was
"Can a machine really think?"

The question had not changed,
only the wording was altered
to confuse the innocent.

I never saw a person's id
I hope to never see one.
But I can tell you if I did
I'd clamp on ego as a lid
Upon the id to keep it hid.
Which is, I gather, what God did
When he first saw a free one.

When nothing can go wrong, it will.

Nothing is ever as simple as it seems.

Everything always costs more money than you have, and takes longer.

If you fool around with a thing long enough, it will eventually break.

If you try to please everybody, somebody is not going to like it.

It is fundamental law of nature that nothing ever quite works out.

It is easier to get into a thing than to get out of it.

If you explain something so clearly that no one can misunderstand it, someone will.

Whatever you want to do, you have to do something else first.

I know that you believe you understand what you think I said, but I am not sure you realize that what you heard is not what I meant.

Your mainstream runs through my left field.

We trained hard ... but it seemed that every time we were beginning to form up into teams we would be reorganized ... I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.

In contrast to learning as selective induction, the central component of the constructivist model is that it does not involve a search through an a priori defined hypothesis space, and so is not an instance of model-based estimation, or parametric regression.  Instead, the constructivist learner builds this hypothesis as a process of activity-dependent construction of the representations that underlie mature skills.

Statistics is formalized pattern recognition.

Mind is what brain does.

Beware the salesman in the guise of a scientist

One person's noise is another person's signal.
