"As each event owes some portion of its nature to that which preceded it, so it imparts some of its nature to that which succeeds it, and thus perpetuates the blended good or evil of itself and its predecessors. The single event may thus live on in its influence along the line of all the ages, assuming new shapes, or if clothing itself in the drapery of new events, ever marching onward and upward in the continually growing affairs of time."
