Scientia is knowledge. It is only in the popular mind that it is equated with facts.

Instead, in the absence of respect for human rights, science and its offspring technology have been used in this century as brutal instruments for oppression.

The respect for human rights, essential if we are to use technology wisely, is not something alien that must be grafted onto science. On the contrary, it is integral to science, as also to scholarship in general.

I knew, however, that it would cost ten times what I had available in order to build a molecular beam machine. I decided to follow a byway, rather than the highway. It is a procedure I have subsequently recommended to beginning scientists in this country, where research strategy is best modelled on that used by Wolfe at the Plains of Abraham.

Science never gives up searching for truth, since it never claims to have achieved it.

When, as we must often do, we fear science, we really fear ourselves. Human dignity is better served by embracing knowledge.

In education the appetite does indeed grow with eating. I have never known anyone to abandon study because they knew too much.
