Two great quotes:

All this was part of Rustin’s central understanding: pragmatism and principle intertwine to make progress.

The principles that Rustin held steadfast, though they may seem unexciting in a political culture that loves romantic extremists, are nonetheless time-tested: Work within a coalition as broad as you can make it. Emphasize logistic efficiency. Relish the metaphoric imagination, but don’t let it run away with your judgment. Accept that perseverance is the best friend of freedom. Although utopianism and visionary overreach may be necessary beacons of freedom, they can, left to their own devices, become its betrayers.
