Reactionaries often describe both Marx and Lenin as theorists, without taking into consideration that their utopias inspired Russia and China - the two countries called upon to lead a new world which will allow for human survival if imperialism does not first unleash a criminal, exterminating war.

I was trained as an economic theorist; my job at MIT was as an economic theorist. At some level that's still part of my identity.

Abhijit Banerjee

What's nice about experiments is that they are much more closely tied to what theorists think about the world than normal empirical research. You can design your experiment to exactly ask the question you want to ask. This is not true about normal empirical research.

In 1997, Alain de Botton published his book 'How Proust Can Change Your Life.' I was charmed by it. I remember using it in a course on cultural criticism for a graduate class that had a mix of theorists and creative writers.

Alongside the flat-earthers, 9/11 truthers and Obama birthers, the anti-vaccine conspiracy theorists have always had a special distinction: They can do immediate and specific damage in a way that the others can't.

Anne Applebaum

I was always a data guy, not a theorist. Theorists can maintain total purity. The data are always messy.

Austan Goolsbee

Jose Marti, known as 'the Apostle of Cuban Independence,' was an influential poet, journalist, and political theorist who became a symbol for the Cuban people's bid for independence. The concepts of freedom, liberty, and self-determination feature prominently in his work.

Ben Rhodes

Usually I am not a conspiracy theorist. I don't believe in the Bilderbergers as a conspiracy or the Trilateralists. But I am certain that the Communists killed JFK. There is a super great book called 'Legend' by Edward Jay Epstein that makes it all perfectly clear.

Ben Stein

I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.

Brian Greene

Theorists can create all sorts of theories which go beyond the Standard Model. But there's not one bit of experimental evidence to point out which way you should go.

Burton Richter

Theorists can be wrong; only nature is always right.

David Gross

Theorists have wonderful ideas which take years and years to be verified.

David Gross

The 'conspiracy theorist' is no longer a crazy person with a tinfoil hat, but they are the Edward Snowdens and the WikiLeaks that bring down major institutions and are the catalysts for social change.

Dean Haglund

I'm not a communist, just a media theorist.

Douglas Rushkoff

It was not until I got my first job, at the University of Washington in Seattle, and began playing chess with Don Gordon, a brilliant young theorist, that I learned economic theory.

Douglass North

As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map.

Edward Witten

Holocaust denial, once the preserve of fringe conspiracy theorists, has mutated into Holocaust obfuscation, equivocation, and specious comparison on a larger scale than ever.

Ephraim Mirvis

Much theoretical work, of course, focuses on existing economic institutions. The theorist wants to explain or forecast the economic or social outcomes that these institutions generate.

Eric Maskin

Reactionaries often describe both Marx and Lenin as theorists, without taking into consideration that their utopias inspired Russia and China - the two countries called upon to lead a new world which will allow for human survival if imperialism does not first unleash a criminal, exterminating war.

Fidel Castro

Without a tutor to help me in the study of Marxism-Leninism, I was no more than a theorist and, of course, had total confidence in the Soviet Union.

Fidel Castro

Whether the ice caps melt, or expand - whatever happens - the anthropogenic global warming theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology.
