The phrase 'mad as a hatter' was coined because hat makers were poisoned by the high levels of mercury used in felt processing; these workers developed a strange, uneven gait as well as strange alterations in their personalities - traits that resembled mental instability.

Frances Beinecke

I think this is really a defining moment for the Arab world. The problem is, it is all going to be about blood, sweat and tears. In certain countries it may be just sweat, and in some countries sweat and tears, and in some countries, as you can see, a lot of blood. I think initial instability is something that we are all extremely nervous of.

Abdullah II of Jordan

I've found that instability from growth comes in waves.

Alan Schaaf

The country is indebted, cloaked by an instability that discards the possibility of development and leaves it hostage to foreign financial markets.

Alberto Fernandez

I do have a sense of displacement as constant instability - the uninterrupted existence of everything that I love and care about is not guaranteed at all. I wait for catastrophes.

Aleksandar Hemon

The Wahhabists are the boogeymen, the guys who will chop the head off any American they catch. And they will destroy Iraq without a second thought if they believe that the instability will benefit them.

Alex Berenson

Previous efforts to eradicate malaria failed for several reasons, including political instability and technical challenges in delivering resources, especially in certain countries in Africa.

Anthony Fauci

When counterterrorist policies are used to suppress peaceful protests and legitimate opposition movements, shut down debate, target human rights defenders, or stigmatize minorities, they fail, and we all lose. Indeed, such responses may cause further resentment and instability and contribute to radicalization.

Antonio Guterres

Torture remains unacceptable and unjustified at all times, including during states of emergency, political instability, or even in a war.

Antonio Guterres

Look at a map of the world: the countries which do not trade much, or which trade only in oil and gas, tend to be in regions which suffer the most social and political instability.

Arancha Gonzalez

In a summer marked by instability in the Middle East and Eastern Europe, I know the world also took notice of the small American city of Ferguson, Missouri - where a young man was killed, and a community was divided. So yes, we have our own racial and ethnic tensions.

Barack Obama

The Mexican debt crisis, Latin American debt crisis, the crises of the 1990s, the Wall Street stock market crash, and other events should have reminded us, and did remind us, that financial instability remains a concern, remains a problem.

Ben Bernanke

It's hard to throw the football when you have some instability at quarterback or if you don't have the weapons around you.

Bill Cowher

I understand how every healthy child, every new road, puts a country on a better path, but instability and war will arise from time to time, and I'm not an expert on how you get out of those things.

Bill Gates

If you look beyond the short term violence and instability, you do see significant activities on the part of the Iraqi people that indicate they understand the commitment necessary to govern themselves. It's not clear how they will do it, but it never is.

Bob Kerrey

We think that Kosovo will continue to serve as a centre of violence and regional instability in future.

Boris Trajkovski

Children in foster care are there through no fault of their own, and they face challenges that would test the resolve of even the most mature adults: frequent moves, early trauma, instability, and in many cases, abuse.

Cathy McMorris Rodgers

Social immobility is driven by family background, instability in childhood and often by parents who don't know how to give children the right start in life.

Chris Grayling

The Black Lives Matter movement can be read as an attempt to keep mourning an open dynamic in our culture because black lives exist in a state of precariousness. Mourning then bears both the vulnerability inherent in black lives and the instability regarding a future for those lives.

Claudia Rankine

In my view - which could be wrong, but it is my field - there is no better formula for social instability than to divide a society between two ascribed characteristics that are seen as opposite.

Daniel Patrick Moynihan

Gordon Brown and Alistair Darling, in hosting the G20 summit and in the budget, must display the same boldness in tackling the instability at home that they do in promoting a worldwide answer to the global meltdown.
