George Bernard Shaw: Irish playwrite, political activist, and Nobel Prize Laureate:

“This is the true joy in life, having a purpose recognized by yourself as a mighty one. Being a force of nature instead of a feverish, selfish little clot of ailments and grievances, complaining that the world will not devote itself to making you happy.

I am of the opinion that my life belongs to the whole community and as long as I live, it is my privilege to do for it what I can. I want to be thoroughly used up when I die, for the harder I work, the more I live.

I rejoice in life for its own sake. Life is no brief candle to me. It is a sort of splendid torch which I have got hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations.”

Quote by Aung San Suu Kyi

“Within a system which denies the existence of basic human rights, fear tends to be the order of the day. Fear of imprisonment, fear of torture, fear of death, fear of losing friends, family, property or means of livelihood, fear of poverty, fear of isolation, fear of failure. A most insidious form of fear is that which masquerades as common sense or even wisdom, condemning as foolish, reckless, insignificant or futile the small, daily acts of courage which help to preserve man's self-respect and inherent human dignity. It is not easy for a people conditioned by fear under the iron rule of the principle that might is right to free themselves from the enervating miasma of fear. Yet even under the most crushing state machinery courage rises up again and again, for fear is not the natural state of civilized man.”

Wendell Berry, "The Long-Legged House"

“We have lived our lives by the assumption that what was good for us would be good for the world. We have been wrong. We must change our lives so that it will be possible to live by the contrary assumption, that what is good for the world will be good for us. And that requires that we make the effort to know the world and learn what is good for it.”

Paul MacCready quote

“Over billions of years on a unique sphere, chance has painted a thin covering of life - complex, improbable, wonderful and fragile. Suddenly, we humans - a recently arrived species, no longer subject to the checks and balances inherent in nature - have grown in population, technology and intelligence to a position of terrible power. We now wield the paintbrush.”
