King's writing on character mostly comes back to one distinction: what a person does under pressure versus what they say when nothing is at stake. His clearest line on it, from Strength to Love (1963), is close to a definition: "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." Character shows up constantly in his other writing too — most famously in "I Have a Dream" (1963), where being judged "by the content of their character" is the specific alternative he wanted to skin color, and in a 1947 college essay on education, where he argued intelligence without character was actually dangerous rather than neutral.
“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.”
This is close to King's working definition of character: not a fixed trait, but something revealed specifically under pressure.
“I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.”
“Intelligence plus character, that is the goal of true education.”
From "The Purpose of Education," an essay King wrote as a Morehouse College student in 1947. He argued a school that produced only intelligence, without character, was training people for harm rather than good.
“The function of education is to teach one to think intensively and to think critically.”
“A man's character is defined by how he engages people who can do nothing for him.”
“The content of a man's character has nothing to do with the color of his skin.”
This line and the fuller "content of their character" passage both come from the I Have a Dream speech, August 28, 1963 — King's clearest statement that character, not race, should be the basis for judgment.
“We must develop and maintain the capacity to forgive.”
“Cowardice asks the question, is it safe? Vanity asks the question, is it popular? But conscience asks the question, is it right?”
“Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness.”
“Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.”
This line is King's warning that good intentions don't excuse a failure to think carefully — sincerity alone isn't character.
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.
Dr. Martin Luther King, Jr.
"Content of Their Character"
The line everyone knows, about children being judged by "the content of their character," comes from the 1963 I Have a Dream speech. But King had been writing about character years earlier, including in a 1947 college essay where he argued that intelligence without character was dangerous, not admirable. Read together, the two show the idea was not a one-time applause line, it was something he'd been working out since he was a student.
