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

We are sometimes asked what the result would be if we put four +’s in one gene. To answer this my colleagues have recently put together not merely four but six +’s.

Free will is located in or near the anterior cingulate sulcus.

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.

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.

I believe in my gut. Most people intellectualize their instincts away, but when you feel something, you have to go for it. A Fistful of Dollars was a great instinct for me, because here I was, a guy who’s doing Rawhide.

Secularism is not only in our constitution but also in our veins. We worship Mother Nature too. We believe that the world is our family.

Whatever you believe, that you will be. If you believe yourselves to be sages, sages you will be tomorrow. There is nothing to obstruct you.

That which I have set out in Latin is not my words but the words of God and of apostles and prophets, who of course have never lied. He who believes shall be saved, but he who does not believe shall be damned. God has spoken.

I do believe in self-help.

Religion is realization; not talk, nor doctrine, nor theories however beautiful they may be. It is being and becoming, not hearing, or acknowledging; it is the whole soul becoming what it believes.

Whether you like it or not, you’re forced to come to the realisation that death is out there. But I don’t fear death, I’m a fatalist. I believe when it’s your time, that’s it. It’s the hand you’re dealt.

Don’t ever forget two things I’m going to tell you. One, don’t believe everything that’s written about you. Two, don’t pick up too many checks.
