You have to understand that PTSD has to be an event that you experience, a very traumatic event. And actually, there is evidence that brain chemistry changes during this event in certain individuals where it's imprinted indelibly forever and there's an emotion associated with this which triggers the condition.

I speak to the black experience, but I am always talking about the human condition.

All the suffering and joy we experience depend on conditions.

Yugoslavia is a multinational community and it can survive only under the conditions of full equality for all nations that live in it.

I believe in unconditional love and equality. Jesus Christ exemplified these qualities.

Corporate social responsibility is measured in terms of businesses improving conditions for their employees, shareholders, communities, and environment. But moral responsibility goes further, reflecting the need for corporations to address fundamental ethical issues such as inclusion, dignity, and equality.

Democratic principles are the result of equality of condition.

Gender equality is more than a goal in itself. It is a precondition for meeting the challenge of reducing poverty, promoting sustainable development and building good governance.

When it comes to protecting workers, labour conditions, labour legislation, the rights for collective bargaining, when you look at our environmental standards, when you look at our public disclosure laws and accountability and securities regulations to ensure that companies abide by the law, we don't have a level playing field with China.

There is great potential for investments that are built around improving social, environmental, and economic conditions.

Here on Earth, we've found organisms that thrive in environmental conditions we would have once thought uninhabitable. The presence of these extremophiles suggests that life could potentially take hold on worlds other than our own.

There are environmental threats to health; there are internal threats to health - genetic conditions, viral threats, diseases like cancer and Parkinson's.

When you buy a jacket, you pick the size to ensure it fits. Similarly, we live in a universe in which the amount of dark energy fits our biological make-up. If the amount of dark energy were substantially different from what we've measured, the environmental conditions would be inhospitable to our form of life.

I reflect back 35 years ago, and look how far we have come in America with our environmental policy to improve the conditions of our air and water, and we have had some real successes.

Education is a work of self-organization by which man adapts himself to the conditions of life.

Purity of personal life is the one indispensable condition for building up a sound education.

The greatest stain upon this great Australian nation's character, without any question, is the great gaps that exist between our Aboriginal brothers and sisters in terms of their health, their education, their living conditions, their incarceration rates and life expectancy. It's a great stain.

Education then, beyond all other devices of human origin, is the great equalizer of the conditions of men, the balance-wheel of the social machinery.

My countrymen, I have given proofs that I am one most anxious for liberties for our country, and I am still desirous of them. But I place as a prior condition the education of the people, that by means of instruction and industry our country may have an individuality of its own and make itself worthy of these liberties.

To every people the land is given on condition. Perceived or not, there is a Covenant, beyond the constitution, beyond sovereign guarantee, beyond the nation's sweetest dreams of itself.

Learning essential stuff is as much a discipline as going to the gym or sticking to a diet, and an excellent antidote for the modern condition of being numb and dumb.
