“Devo confessare, amici miei, che la strada da percorrere non sarà sempre agevole.”

Originale

I must confess, my friends, the road ahead will not always be smooth.

King's often repeated expression that "The arc of the moral universe is long, but it bends towards justice" was his own succinct summation of sentiments echoing those of Theodore Parker, who, in "Of Justice and the Conscience" (1853) asserted: "I do not pretend to understand the moral universe; the arc is a long one, my eye reaches but little ways; I cannot calculate the curve and complete the figure by the experience of sight; I can divine it by conscience. And from what I see I am sure it bends towards justice."
1960s, Where Do We Go from Here: Chaos or Community? (1967)
Contesto: I must confess, my friends, the road ahead will not always be smooth. There will be still rocky places of frustration and meandering points of bewilderment. There will be inevitable setbacks here and there. There will be those moments when the buoyancy of hope will be transformed into the fatigue of despair. Our dreams will sometimes be shattered and our ethereal hopes blasted. We may again with tear-drenched eyes have to stand before the bier of some courageous civil rights worker whose life will be snuffed out by the dastardly acts of bloodthirsty mobs. Difficult and painful as it is, we must walk on in the days ahead with an audacious faith in the future. … When our days become dreary with low-hovering clouds of despair, and when our nights become darker than a thousand midnights, let us remember that there is a creative force in this universe, working to pull down the gigantic mountains of evil, a power that is able to make a way out of no way and transform dark yesterdays into bright tomorrows. Let us realize the arc of the moral universe is long but it bends toward justice.
