The first principle of non-violent action is that of non-cooperation with everything humiliating.
- Cesar Chavez
Anger is an acid that can do more harm to the vessel in which it stands than to anything on which it is poured.
Security is mostly a superstition. It does not exist in nature, nor do the children of humans as a whole experience it. Avoiding danger is not safer in the long run than outright exposure. Life is either a daring adventure, or nothing.
- Helen Keller
Difficulties are meant to rouse, not discourage. The human spirit is to grow strong by conflict.
- William Ellery Channing
Don't ever let them pull you down so low as to hate them. (also cited as: I will permit no man to narrow and degrade my soul by making me hate him.)
- Booker T. Washington
The sad truth is that most evil is done by people who never make up their minds to be good or evil.
- Hannah Arendt
Sensitivity to the immense needs of humanity brings with it a spontaneous rejection of the arms race, which is incompatible with the all out struggle against hunger, sickness, under-development and illiteracy.
- Pope John Paul II
Hatred paralyzes life; love releases it. Hatred confuses life; love harmonizes it. Hatred darkens life; love illuminates it.
- Martin Luther King, Jr.
And they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
- Isaiah 2:4
Let all bear in mind that a society is judged not so much by the standards attained by its more affluent and privileged members as by the quality of life which it is able to assure for its weakest members.
- H.E. Javier Perez de Cuellar
All violence consists in some people forcing others, under threat of suffering or death, to do what they do not want to do.
- Leo Tolstoy
Peace is the skillful management of conflict.
- Kenneth Boulding
No one is so foolish as to prefer to peace, war, in which, instead of sons burying their fathers, fathers bury their sons.
Peace is not the product of a victory or a command. It has no finishing line, no final deadline, no fixed definition of achievement. Peace is a never-ending process, the work of many decisions.
- Oscar Arias
If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart.
