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.

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.

Today, Academies of Science use their influence around the world in support of human rights.

In nation after nation, democracy has taken the place of autocracy.

No one has a monopoly on truth, and science continues to advance. Yesterday's heresies may be tomorrow's conventional wisdom.

All that socialism means to me, to be very frank with you, is democracy with a small 'd.' I believe in democracy, and by democracy, I mean that, to as great an extent as possible, human beings have the right to control their own lives. And that means that you cannot separate the political structure from the economic structure.

It used to be that I was known as 'the longest-serving independent in the history of the United States Congress,' which is true. Now I'm a 'self-professed democratic socialist.' Things change when you run for president.
