A. N. Wilson

Aasif Mandvi

Abhijit Banerjee
Here is an entirely banal idea that I think has the potential to change the world: Take evidence seriously. Taking evidence seriously does not mean privileging numbers over all other forms of knowledge - theories, narratives, images. Nor does it mean the kind of radical skepticism that questions everything to the point where no action is possible.
You are right, but the weakness does not come from the millions of Muslims in the world. They do not mind being radical, they have no fear to speak out and to protest and to jihad.
Abu Bakar Bashir

Adam Cohen

Adolfo Aguilar Zinser

Agnes Varda
I didn't see myself as a woman doing film but as a radical film-maker who was a woman.
I remember leaving the first 'Matrix' movie feeling completely radicalized, completely changed. I think we all, from our ordinary lives, like to think about putting ourselves into these extraordinary situations and wonder how we'd respond.
Aisha Tyler
I see the first 'Bourne' movie as really kind of a fulcrum in changing the modern action film, where things are really gritty and really character-driven. Think about how the entire Bond franchise was completely radicalized by Bourne.
The Republican agenda is a radical vision in which Medicaid is slashed to the bone - in which we start to balance the budget on the backs of, literally, our most vulnerable citizens.
Al Franken
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.
Alain Aspect
In today's distorted world of 'human rights,' truth takes a back seat to ideology, and false claims - especially those that 'support' radical ideologies - persist even after they have been exposed.
Alan Dershowitz
It's about time we all faced up to the truth. If we accept the radical homosexual agenda, be it in the military or in marriage or in other areas of our lives, we are utterly destroying the concept of family.
Alan Keyes
Right from the outset, the prevailing mindset in British comics fandom was a radical and progressive one. We were all proto-hippies, and we all thought that comics would be greatly improved if everything was a bit psychedelic like Jim Steranko.
Alan Moore
In the sixties, for anybody to suggest that the government didn't have our best interests at heart and policemen sometimes killed people would have automatically made them a radical firebrand lefty. That's not the case anymore.

I am still radical!
I have equal contempt for both left and right radicals.
I feel that Julian Assange came to be both paranoid and self-regarding in ways that ultimately undermined his own mission. And so, the transparency radical became a secret-keeper instead of a secret-leaker. And that, I think, is a big problem.
Being an old radical, I like films like Spartacus. I could relate to the hero.
Wear the badge of environmental radicalism, and you're a citizen automatically under suspicion.

Working-class Americans want a clear champion, and there is nothing radical about moral clarity in 2018.
Syriza is what it is: a radical, left-wing party that feels the pulse of the times, knows what's at stake, and is after a wide consensus and unity for political change in Greece. This is something that departs from the narrow limits of the radical left.
I think it's often assumed that the role of poetry is to comfort, but for me, poetry is the great unsettler. It questions the established order of the mind. It is radical, by which I don't mean that it is either leftwing or rightwing, but that it works at the roots of thinking.
June Jordan, who died of cancer in 2002, was a brilliant, fierce, radical, and frequently furious poet. We were friends for thirty years. Not once in that time did she step back from what was transpiring politically and morally in the world. She spoke up, and led her students, whom she adored, to do the same.

In truth, Wall Street is in for a radical makeover. Fewer people, lower margins, lower risk, lower compensation - and ultimately, fewer talented people. It is likely to change the culture of an industry that for nearly a century has been the money center of the world.
In the first years after the systemic transition, our screens showed American entertainment that had not been available before, or had been available only sporadically.

Radical simply means 'grasping things at the root.'
If Republicans are defeated in 2008, God help us all because Radical Islamic fascists will do anything by any means necessary to rid the world of the 'infidels': the enemy. In their eyes, that is America.
