Freeman Dyson

It has become part of the accepted wisdom to say that the twentieth century was the century of physics and the twenty-first century will be the century of biology.

Lucky individuals in each generation find technology appropriate to their needs.

The world of science and the world of literature have much in common. Each is an international club, helping to tie mankind together across barriers of nationality, race and language. I have been doubly lucky, being accepted as a member of both.

Unfortunately things are different in climate science because the arguments have become heavily politicised. To say that the dogmas are wrong has become politically incorrect.

Biology is now bigger than physics, as measured by the size of budgets, by the size of the workforce, or by the output of major discoveries and biology is likely to remain the biggest part of science through the twenty-first century.

Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science.

The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.

It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment.

What the world needs is a small, compact, flexible fusion technology that could make electricity where and when it is needed. The existing fusion program is leading to a huge source of centralized power, at a price that nobody except a government can afford.

Technology is a gift of God. After the gift of life it is perhaps the greatest of God's gifts. It is the mother of civilizations, of arts and of sciences.

I see a bright future for the biotechnology industry when it follows the path of the computer industry, the path that von Neumann failed to foresee, becoming small and domesticated rather than big and centralized.

The purpose of thinking about the future is not to predict it but to raise people's hopes.

I have the freedom to do what I want... bright people to talk to every day.

It's better to get mugged than to live a life of fear.

A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.

We have no reason to think that climate change is harmful if you look at the world as a whole. Most places, in fact, are better off being warmer than being colder. And historically, the really bad times for the environment and for people have been the cold periods rather than the warm periods.
