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. – Freeman Dyson
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. – Freeman Dyson
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. – Freeman Dyson

And historically, the really bad times for the environment and for people have been the cold periods rather than the warm periods. – Freeman Dyson
