“There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.”

In the fullness of time, educated people will believe there is no soul independent of the body, and hence no life after death.

It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.

My own prejudices are exactly the opposite of the functionalists’: “If you want to understand function, study structure”.

An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.

It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less secure than our other deductions about the general nature of the genetic code.

It is notoriously difficult to define the word living.

You’re nothing but a pack of neurons.

One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.

I also suspect that many workers in this field [molecular biology] and related fields have been strongly motivated by the desire, rarely actually expressed, to refute vitalism.

Christianity may be OK between consenting adults in private but should not be taught to young children.

Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.

There is no form of prose more difficult to understand and more tedious to read than the average scientific paper.

A knowledge of the true age of the Earth and of the fossil record makes it impossible for any balanced intellect to believe in the literal truth of every part of the Bible in the way that fundamentalists do.

A comparison between the triplets tentatively deduced by these methods with the changes in amino acid sequence produced by mutation shows a fair measure of agreement.

A busy life is a wasted life.

Exploratory research is really like working in a fog. You don’t know where you’re going. You’re just groping. Then people learn about it afterwards and think how straightforward it was.

A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber room of his library, where he can get it if he wants it.

Let’s be open-minded, but not so open-minded that our brains drop out.

Talking to a drunk person was like talking to an extremely happy, severely brain-damaged three-year-old.

If you’re willing to suffer, and I mean suffer, your brain and body once connected together, can do anything.

The most important part of the body is the brain. Of my face, I like the eyebrows and eyes.

The tradition of all dead generations weighs like a nightmare on the brains of the living.

Perhaps consciousness arises when the brain’s simulation of the world becomes so complex that it must include a model of itself.

There is nothing like chess to keep the brain smart, and give it a workout.
