I recall coming across a line by the late Charles Tilly when he said, "The conditions for the possibility of social movements have been called into question in the twenty-first century." And I said to myself, my god, a society in history without social movements, for me, is very difficult to live in.

There's simply no philosophizing without a love of wisdom, absolutely.

When ordinary people wake up, elites begin to tremble in their boots.

I know my dear brother, President [Barack] Obama, has a bust of Martin King right there in the Oval Office, but the question is are is he going to be true to who that Martin Luther King, Jr., actually is? King was concerned about what? The poor. He was concerned about working people. He was concerned about quality jobs. He was concerned about quality housing. He was concerned about precious babies in Vietnam, the way we ought to be concerned about precious babies in Afghanistan and precious babies in Tel Aviv and precious babies in Gaza.

Justice is what love looks like in public.

To accept your country without betraying it, you must love it for that which shows what it might become. America -- this monument to the genius of ordinary men and women, this place where hope becomes capacity, this long, halting turn of 'no' into the 'yes' -- needs citizens who love it enough to re-imagine and re-make it.

Martin Luther King was an extremist of love.
