Martin Luther King Jr. was shot and killed on April 4, 1968, outside a Tennessee motel room. He was just 39 years old.

The pastor, activist, and humanitarian led an incredibly profound and impactful life. Largely responsible for helping to pass the Civil Rights Act of 1964, King organized, marched, and became accustomed to being inconvenienced and uncomfortable for the greater good.  

King's mission toward peace, black freedom, and equality for all didn't stop when he died.

Though his passing was a painful point in American history, his words continue to live on. A radical and peacemaker, a preacher and a father, an advocate for the poor and a criticizer of the indifferent, King's life and teachings were just as complex as he was.      

To remember his legacy, we have 50 of his quotes that offer insight into his beliefs about race, class, and humanity itself.  

1. "The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy."  

2. "Whatever affects one directly, affects all indirectly. ... I can never be what I ought to be until you are what you ought to be. ... This is the interrelated structure of reality."

3. "I think that we've got to see that a riot is the language of the unheard. And, what is it that America has failed to hear? It has failed to hear that the economic plight of the Negro poor has worsened over the last few years."

4. "An individual has not started living until he can rise above the narrow confines of his individualistic concerns to the broader concerns of all humanity."

6. "A lie cannot live."

7. "Injustice anywhere is a threat to justice everywhere."  

8. "A riot is the language of the unheard."

9. "In the end, we will remember not the words of our enemies, but the silence of our friends."

10. "Let us develop a kind of dangerous unselfishness."

11. "Nonviolence is absolute commitment to the way of love. Love is not emotional bash; it is not empty sentimentalism. It is the active outpouring of one’s whole being into the being of another."

12. "Why is equality so assiduously avoided? Why does white America delude itself, and how does it rationalize the evil it retains?"

13.  "We have deluded ourselves into believing the myth that capitalism grew and prospered out of the Protestant ethic of hard work and sacrifices. The fact is that capitalism was built on the exploitation and suffering of black slaves and continues to thrive on the exploitation of the poor — both black and white, both here and abroad."

14. "If you can’t fly, run. If you can’t run, walk. If you can’t walk, crawl, but by all means, keep moving."

15. "The function of education, therefore, is to teach one to live intensively and to think critically. ... Intelligence plus character — that is the goal of true education."  

16. "Nonviolence is a powerful and just weapon. Indeed, it is a weapon unique in history, which cuts without wounding and ennobles the man who wields it."

17. "First, I must confess that over the past few years I have been gravely disappointed with the white moderate. I have almost reached the regrettable conclusion that the Negro's great stumbling block in his stride toward freedom is not the White Citizen's Counciler or the Ku Klux Klanner, but the white moderate, who is more devoted to 'order' than to justice."

18. "We must accept finite disappointment but never lose infinite hope."

19. "The Negro has no room to make any substantial compromises because his store of advantages is too small. He must press unrelentingly for quality, integrated education or his whole drive for freedom will be undermined by the absence of a most vital and indispensable element — learning."

24. "No, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream."

25. "Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that."

26. "Like anybody, I would like to live a long life — longevity has its place. But I'm not concerned about that now. I just want to do God's will."

36. "The ultimate tragedy ... was not the brutality of the bad people, but the silence of the good people."
