Admittedly, the body of scientists, as a whole, does uphold the authority of science over the lay public. It controls thereby also the process by which young men are trained to become members of the scientific profession.

The first thing to make clear is that scientists, freely making their own choice of problems and pursuing them in the light of their own personal judgment, are in fact co-operating as members of a closely knit organization.

Admittedly, scientific authority is not distributed evenly throughout the body of scientists; some distinguished members of the profession predominate over others of a more junior standing.

Individual scientists like myself - and many more conspicuous - pointed to the dangers of radioactive fallout over Canada if we were to launch nuclear weapons to intercept incoming bombers.

Our assessment of socio-economic worth is largely a sham. We scientists should not lend ourselves to it - though we routinely do. We should, instead, insist on applying the criterion of quality.

Others think it the responsibility of scientists to coerce the rest of society, because they have the power that derives from special knowledge.

Some dreamers demand that scientists only discover things that can be used for good.

Scientists and scholars should constitute themselves as an international NGO of exceptional authority.

Though neglectful of their responsibility to protect science, scientists are increasingly aware of their responsibility to society.

A large fraction of the most interesting scientists have read a lot of SF at one time or another, either early enough that it may have played a part in their becoming scientists or at some later date just because they liked the ideas.

Facts are the air of scientists. Without them you can never fly.

The conception that, instead of this, contemporary society is at or near a turning point is very prominent in the views of a school of social scientists who, though they are still comparatively few, are getting more and more of a hearing.

The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.

As this body of knowledge has evolved, a much more critical job for researchers and scientists has evolved into explaining and educating policy makers and the public to the risks of global warming and the possible consequences of action or of no action.

Although reading the classics in Latin in school may be not as fulfilling as it would be at a more mature age, few scientists can afford the time for such diversion later in life.
