(Courtesy Eric Liu) Division has become an everyday reality for most Americans. Reading or scrolling through the news inevitably leads to some kind of partisan rancor or social conflict. And it can be difficult to think that there is anything other than deeper division in the country's future. Of course, division is nothing new. Political and social strife is woven into the history of American life, a counterweight to the lofty idea of national unity that is central to the national mythology. And, in the midst of a pandemic that has deepened some divisions, that idea of unity — the coming together of the American people toward a singular purpose — appears to be fading as division dominates.
