Not sure I completely understand, but I guess he's saying young people have ideas, not actions (experiences) and we cannot reduce politics or the discuss of morals into absolutes, for there is no absolute answer. It's not only the inability to accept vaugenes and ambiguity but also the inability to keep communal good or the good of the state above one's individual good, which hedonist individual lacks. And therefore, not all are ready to study or discuss this.

Hope I'm getting it right :p
