In what is now an annual tradition, Apple has dedicated its homepage at to celebrating Martin Luther King Jr Day. 

Each year, Apple chooses a one-sentence quote, which this year is:

Whatever affects one directly affects all indirectly

It is again take from King’s famous Letter from a Birmingham Jail in which he addressed criticism from other Christians who considered he was an outsider interfering in matters which didn’t affect him- and breaking the law to do so. 

I am in Birmingham because injustice is here (…) I am cognizant of the interrelatedness of all communities and states. I cannot sit idly by Atlanta and not be concerned about what happened in Birmingham. Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny.  Whatever affects one directly, affects all indirectly. Never again can we afford to I’ve with the narrow, provincial “outside agitator” item. Anyone who lives inside the United States can never be considered an outsider anywhere with its bounds. 

He went on to observe that legality or illegality is not necessarily the same as right is wrong. 

We should never forget that everything Adolf Hitler did in Germany was “legal” and everything the Hungarian freedom fighters did Hungary was “illegal.”

Apple CEO Tim Cook also tweeted a sentence from King’s Nobel Peace Prize acceptance speech. 

In that speech, king said that we must favor hope and faith over despair. 

I accept this award today with an abiding faith in America and an audacious faith in the future of mankind. I refuse to accept despair as the final response to the ambiguities of history. I refuse to accept the idea that the “isles” of man’s present nature make him morally incapable of reaching up for the eternal “outness” that forever confronts him. I refuse to accept the idea that man is mere flotsam and jetsam in the river of live, cable to influence the unfolding events which surround him. I refuse to accept the view that mankind is to tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. 

You can watch the full speech below. 

Martin Luther King Jr Day is a federal holiday in the U.S. to mark the birthday of the civil rights leader. The holiday was signed into law in 1983 and first observed in 1986, but opposition in some states meant that it wasn’t until the year 2000 that it was officially observed across the entire country.
