" The foolish and the dead alone never change their opinion. The course of a great statesman resembles that of navigable rivers, avoiding immovable obstacles with noble bends of concession, seeking the broad levels of opinion on which men soonest settle and longest dwell, following and marking the almost imperceptible slopes of national tendency, yet always aiming at direct advances, always recruited from sources nearer heaven, and sometimes bursting open paths of progress and fruitful human commerce through what seem the eternal barriers of both. "

― James Russell Lowell , Abraham Lincoln
