>> i stumbled on this from david foster wallace no less. >> rose: one of the favorites on this program. >> i know those interviews well because i'm such a student of david foster wallace as an individual as well as writer. he wrote a very interesting article about the first john mccain presidential campaign back in the rolling stone and rips very wallace-like on leadership and writes this, "real leaders are individuals who help us overcome the limitations of our own weaknesses and laziness and selfishness and fears and get us to do harder and better things than we can get ourselves to do on our own." >> rose: boy, i like that. aren't we longing as a citizenry for leaders that can do that for us? >> rose: i think that's a big question in this moment our history. where are our leaders and what are we expecting out of them? >> we're not seeing enough of what most of us want and need when we think of courageous leaders. >> rose: i think a great leader how in present times or in past, they have to have some sense of the ability to define the moment so that it becomes a paramount concern. >>
