“Tis hard if all is false that I advance,
A fool must now and then be right by chance.”

Speaking on right-to-work laws in 1961, as quoted in Now Is the Time. Dr. Martin Luther King Jr. on Labor in the South: The Case for a Coalition (January 1986)
1960s
Context: In our glorious fight for civil rights, we must guard against being fooled by false slogans, such as 'right to work.' It is a law to rob us of our civil rights and job rights. It is supported by Southern segregationists who are trying to keep us from achieving our civil rights and our right of equal job opportunity. Its purpose is to destroy labor unions and the freedom of collective bargaining by which unions have improved wages and working conditions of everyone…Wherever these laws have been passed, wages are lower, job opportunities are fewer and there are no civil rights. We do not intend to let them do this to us. We demand this fraud be stopped. Our weapon is our vote.

On the Mindless Menace of Violence (1968)
Context: Yet we know what we must do. It is to achieve true justice among our fellow citizens. The question is not what programs we should seek to enact. The question is whether we can find in our own midst and in our own hearts that leadership of humane purpose that will recognize the terrible truths of our existence. We must admit the vanity of our false distinctions among men and learn to find our own advancement in the search for the advancement of others. We must admit in ourselves that our own children's future cannot be built on the misfortunes of others. We must recognize that this short life can neither be ennobled or enriched by hatred or revenge.

Variant: It is better to be silent and be thought a fool than to speak and remove all doubt.

"I am a parcel of vain strivings tied" http://rpo.library.utoronto.ca/poem/3247.html, st. 1 (1841)
Context: I am a parcel of vain strivings tied
By a chance bond together,
Dangling this way and that, their links
Were made so loose and wide,
Methinks,
For milder weather.
