Last week, Martin Luther King, Jr. would have celebrated his 85th birthday in an America that, in myriad ways, is a freer, fairer, and more just nation than the one he knew. Today, we pause to remember the man for daring to dream of equality of personhood and opportunity; for having the courage to transform what he called “the jangling discord of our nation into a beautiful symphony of brotherhood”; and — as President Obama put it so lyrically last year — for giving a “mighty voice to the quiet hopes of millions” and offering a “salvation path for oppressed and oppressors alike.”
