Real Reason For Separating Church And State

Politics at its best can't be too pure, since it must account for people at their worst, William Galston, a former Bill Clinton adviser, argues:

While politics is not without norms and standards, it must reflect the nature of the human species as self-interested and passionate as well as reasonable--and as capable of destruction as well as cooperation. Political norms and standards must also take into account the distinctive difficulties of collective action and the means sometimes needed to enforce compliance. If we look at political life from too high an altitude, we can no longer see it as it is.
