Military commanders like to say that “quantity has a quality all its own.” It’s a shorthand way of saying that greater numbers of inferior weapons or troops often can beat smaller, superior forces. Given that Monday marks the first birthday of the declaration of the Islamic State of Iraq and Greater Syria, it’s also worth noting that the passage of time, too, has a quality all its own. The quantity of time counts, as days turn into weeks, and months have become a year. Time isn’t an inert presence, either on the physical battlefield or in the war of ideas. It’s a measure of will, a magnet to attract followers, and a manifestation of reality. Bottom line: persistence produces power.
