But as a German - and I am German-born - we Germans are condemned once again to be radical revisionists.

We must make a radical turn, at 360 degrees.

I am a radical.

Radical Chic, after all, is only radical in Style; in its heart it is part of Society and its traditions.

If a radical devolution of powers was possible, it would have been done before. The assumption of states' rights is gone. There's no support for it in the Supreme Court and there's no support for it in public opinion.

To be truly radical is to make hope possible rather than despair convincing.

Yesterday NPR fired me for telling the truth. The truth is that I worry when I am getting on an airplane and see people dressed in garb that identifies them first and foremost as Muslims. This is not a bigoted statement. It is a statement of my feelings, my fears after the terrorist attacks of 9/11 by radical Muslims.

At some point we must realize that actively defending against radical Islamic teachings is not a matter of cultural relativity. It is a matter of universally recognized human rights.

Radical Islamic fundamentalists harbor contempt for our democratic way of life and, given the opportunity, will stop at nothing to accomplish their goal of bringing our country to its knees.

But the threat posed by the radical Islamists represents an unusual conflict, unlike any experienced by our nation before: we face an enemy that is not a state.

Radical constructivism, thus, is radical because it breaks with convention and develops a theory of knowledge in which knowledge does not reflect an 'objective' ontological reality.

The gift of loneliness is sometimes a radical vision of society or one's people that has not previously been taken into account.

I remain optimistic. What we've seen in Europe and the rest of the world is that freedom has a much stronger attraction than radical fundamentalism.

Despite a few really bad days we had quite a lot of fun making Low, especially when all the radical ideas were making sense and things were starting to click.

Another symptom of progress toward the Singularity: ideas themselves should spread ever faster, and even the most radical will quickly become commonplace.
