"Power and Love" (1926)
Context: p> Every morning
I shall concern myself anew about the boundary
Between the love-deed-Yes and the power-deed-No
And pressing forward honor reality.We cannot avoid
Using power,
Cannot escape the compulsion
To afflict the world,
So let us, cautious in diction
And mighty in contradiction,
Love powerfully.</p
