View this quote in the context of "democratic nation building" in Afghanistan. What he's saying is that the polis needs to be self-controlled, educated, and SELF-policed in order to operate as a functioning and thriving society. It is not a comment on a police state. It is a comment in the nature of man and the necessity for sobriety, not mob or emotional rule. This is a particularly scathing rebuke of the American social-media- and cable-news-fed knee-jerking uncritical thinkers rioting in Baltimore, MD or Ferguson, MO and killing people over a cartoon in a Danish newspaper. Such people, the quote says, are quick to act on emotion and not reason. The death or absence of critical thought and self control may well lend to the death of Western civilization as we know it. (I think amoralism will do it too and faster, but that's not what we're talking about right now.)
