“Todo hombre debe decidir si caminará a la luz del altruismo creativo o en la oscuridad del egoísmo destructivo. Éste es el juicio. La pregunta más urgente, e ineludible, de la vida es: ¿Qué estás haciendo por los demás?”

“A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will look at thousands of working people displaced from their jobs with reduced incomes as a result of automation while the profits of the employers remain intact, and say: “This is not just.” It will look across the oceans and see individual capitalists of the West investing huge sums of money in Asia, Africa and South America, only to take the profits out with no concern for the social betterment of the countries, and say: “This is not just.” It will look at our alliance with the landed gentry of Latin America and say: “This is not just.” The Western arrogance of feeling that it has everything to teach others and nothing to learn from them is not just. A true revolution of values will lay hands on the world order and say of war: “This way of settling differences is not just.” This business of burning human beings with napalm, of filling our nation’s homes with orphans and widows, of injecting poisonous drugs of hate into the veins of peoples normally humane, of sending men home from dark and bloody battlefields physically handicapped and psychologically deranged cannot be reconciled with wisdom, justice and love. A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death. America, the richest and most powerful nation in the world, can well lead the way in this revolution of values. There is nothing to prevent us from paying adequate wages to schoolteachers, social workers and other servants of the public to insure that we have the best available personnel in these positions which are charged with the responsibility of guiding our future generations. There is nothing but a lack of social vision to prevent us from paying an adequate wage to every American citizen whether he be a hospital worker, laundry worker, maid or day laborer. There is nothing except shortsightedness to prevent us from guaranteeing an annual minimum—and livable—income for every American family. There is nothing, except a tragic death wish, to prevent us from reordering our priorities, so that the pursuit of peace will take precedence over the pursuit of war. There is nothing to keep us from remolding a recalcitrant status quo with bruised hands until we have fashioned it into a brotherhood.”

“I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even the enemy”

“The plain, inexorable fact was that any attempt of the America Negro to overthrow his oppressor with violence would not work...The courageous efforts of our own insurrectionist brothers, such as Denmark Vassey and Nat Turner, should be eternal reminders to us that a violent rebellion is doomed from the start. Anyone leading a violent rebellion must be willing to make an honest assessment regarding the possible casualties to a minority population confronting a well-armed, wealthy majority with a fanatical right wing that would delight in exterminating thousands of black men, women, and children.”

“I have a dream today” 

“In the treatment of poverty nationally, one fact stands out: there are twice as many white poor as Negro poor in the United States. Therefore I will not dwell on the experiences of poverty that derive from racial discrimination, but will discuss the poverty that affects white and Negro alike.”

“There can be no deep disappointment where there is not deep love.”

“Individuals may see the moral light and voluntarily give up their unjust posture; but... groups tend to be more immoral than individuals.”

“I have consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek. I have tried to make clear that it is wrong to use immoral means to attain moral ends. But now I must affirm that it is just as wrong, or perhaps even more so, to use moral means to preserve immoral ends.”

“One has a moral responsibility to disobey unjust laws.”

“He who passively accepts evil is as much involved in it as he who helps to perpetrate it.”

“La oscuridad no puede conducirte fuera de la oscuridad; sólo la luz puede hacer eso. El odio no puede conducirte fuera del odio; sólo el amor puede hacer eso.”

“The time has come for an all-out war against poverty. The rich nations must use their vast resources of wealth to develop the underdeveloped, school the unschooled, and feed the unfed. Ultimately a great nation is a compassionate nation. No individual or nation can be great if it does not have a concern for "the least of these".”

“The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.”

“One has not only a legal but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws. I would agree with St. Augustine that ' an unjust law is no law at all.”
